Mineral fertilizer spreader operating manual. Operation and adjustment of the machine. Calculation of the actual load on the front axle

Fertilizer rate is regulated by changing the size of the gap above the conveyor using a flap on the rear wall of the body. Slot size for different types fertilizer and application rate is taken from the table in the instructions for the machine and placed on a metal plate on the rear side of the spreader body.

The fertilizer application rate is also regulated by changing the gear ratio of the feed conveyor drive mechanism by shifting the drive chain to the corresponding pairs of sprockets.

Uniform distribution of fertilizers the width of the grip is regulated by moving the fertilizer guide along its guides and changing the position of the movable divider walls.

Moving the fertilizer guide forward along the spreader leads to a change in the place of fertilizer supply closer to the periphery of the discs. This causes a decrease in the initial speed of the fertilizer particles coming off the disks, which makes it possible to increase their concentration in the middle part of the sown strip.

The movement of the fertilizer guide in the opposite direction leads to a shift in the place of fertilizer supply closer to the centers of the disks, therefore, to an increase in the initial velocity of the particles, which allows increasing the concentration of fertilizers along the edges of the sown strip.

The same effect can be obtained by turning the movable divider walls towards the centers of the spreading discs, and the opposite effect can be obtained by turning in the opposite direction.

Tension of the web of the feeding conveyor is regulated by moving its driven shaft with the help of special screws. In this case, the conveyor bars must be adjacent to the floor of the body, and at the bottom have a deflection arrow of up to 10 mm. Before adjustment, it is necessary to carefully clean the streams of the floor of the body from fertilizers. When making adjustments, make sure that the tension of the branches is the same. It is especially necessary to carefully monitor the correct adjustment of the conveyor in the first 30 ... 50 hours of operation, when it is intensively drawn out and run in.

The spreader working width is 6-14 m, depending on the applied fertilizers and weather conditions. With a wind protection device, the working width is 6m. The spreader is aggregated with tractors of class 14 kN, equipped with hydraulic hooks and plug connectors for connecting electrical equipment.

When preparing for operation of the tractor with the MVU-5 spreader, a track of 1800 mm is set. Check the pressure in the tires of the spreader wheels and, if necessary, bring it to the nominal value of 0.35 MPa.

Connect the spreader to the hydraulic hook of the tractor, raise the drawbar and fix it in the upper position. Mount safety chains and electrical equipment of the tractor and spreader.

Before testing the machine in motion, the metering gate is raised so that the conveyor passes freely under the gate, the bottom of the body is cleaned of fertilizers. After that, the tension of the conveyor is adjusted by moving the driven shaft with tension screws. The tension is considered normal if its lower branch barely touches the guides. Excessive tension of the conveyor leads to intensive wear. Skewed conveyor and the presence of curved links is not allowed.

For making solid mineral fertilizers, in addition to the MVU-5 spreader, the industry produces machines similar to it in design and technological process 1-RMG-4, MVU-8 and MVU-16 with a carrying capacity of 4, 10 and 6 tons, respectively. They are aggregated with tractors MTZ-80, T-150K these Spreaders differ in design from MVU-5 in that the feed conveyors are driven from running wheels.

Spreader MVU-8

The MVU-8 spreader differs from the MVU-5 spreader by its higher carrying capacity and chassis design. The chassis is single-axle with a pair of right and left wheels connected according to the “tandem” scheme. This design ensures that the spreader runs smoothly on uneven fields.

The feed conveyor of the spreader is driven from the rear right wheel through the cardan shaft and chain drives. When the spreader is operating, the cardan shaft is connected to the axis of the running wheel by a coupling driven by the tractor's hydraulic system. At the ends of the gons, this drive is turned off.

The drive of the spreading discs MVU-8 is carried out from the power take-off shaft (PTO) of the tractor through the cardan shaft, V-belt drives and bevel gears, on the driven shafts of which they are fixed.

The mechanisms for setting a given application rate and adjusting the uniformity of fertilizer distribution over the field surface are fundamentally no different from the design of the corresponding units on the spreader 1-RMG-4, and the procedure for setting them is the same.

In the case of using spreaders of the MVU type for the transportation of bulk materials, the spreading discs are removed, the feed conveyor is driven from the PTO of the tractor, which allows unloading the delivered material when the unit is stopped.

Any person close to the earth knows that high yields cannot be seen without mineral fertilizers. By observing the right proportions of their application, you can get excellent results and good income from the sale of your products. The RUM-5 unit, called a fertilizer spreader, will help you quickly and accurately distribute fertilizer across the field.

This device has been made since 1985 in the city of Neftekamsk, at the Bashselmash enterprise. Its more modern name is MVU-5. Factory designers have developed a unit that is very similar to the popular 1-RMG-4 spreader. The differences of the new machine, attached to the MTZ-80, were the operation of all mechanisms from the tractor power take-off shaft, as well as the running gear, made according to the "tandem" type. The design has become more perfect over time, but has not undergone fundamental changes.

Purpose

With this unit, it is possible to fertilize the soil with solids of various densities in the form of powder, granules or crystals. In particular, it can be ammonium nitrate, superphosphate, potassium salt, dolomite and lime flour, and other fertilizers. They can be introduced into the soil in spring or autumn, as well as carry out summer top dressing of intensively growing cereals.

It can be used in all regions except highlands. With its help, not only fertilizers are scattered and transported, but also sand, lime, and various chemicals that are in a loose state.

Advantages and disadvantages

Advantages:

• Easy setup of the unit, ease of use.
• Regulation of the dose of fertilizer application by changing the height of the seed slot. The instructions for the machine provide these data for each type of fertilizer.
• It is possible to scatter useful substances both over the entire width of the field, and only along the edges or in the middle.
• Existence of the mechanism providing the maximum uniformity of top dressing on all width (to a maximum).

Disadvantages:

• Compared to mounted spreaders equipped with a very precise dosing system, the uniformity of work is somewhat lower.
• The inability to move independently - you need a tractor.

Device

The metal frame is equipped with a drawbar and a loop for attachment to the tractor. A five-ton welded body, where fertilizers are poured, is part of the frame. Inside the body there is a plate-bar type conveyor. It is driven either by a tractor power take-off shaft (if more than six tons of fertilizer is applied per hectare), or (with a smaller amount of fertilizer) by a shaft located inside the axle shaft of the right rear wheel.

The conveyor feeds the bulk mass to the centrifugal seeding discs, each of which is equipped with four fluted blades fixed perpendicular to each other. The movement on them comes from the tractor PTO. Cardan, bevel-type gearboxes, V-belt profiles and satellite shafts participate in the transmission of motion.

To ensure that fertilizers are unloaded more evenly, the body has a bimetallic fertilizer-guide shield mounted on side supports. The dosing gate, moving along the skids in the rear of the body, is controlled by a handwheel mounted on the shaft. Two sprockets mesh with the rails to adjust the damper height.

Chassis - a bogie with balancers, designed as a "tandem" and not having springs. A split-type wheel is attached to the hub with six studs and nuts, on which there is a brake drum. The unit has two types of brakes: mechanical (intended for braking in the parking lot) and pneumatic, single-wire. The latter is controlled from the tractor cabin, by a pedal. You can manually brake using a crane. This stops the front wheels.

There is a plug for connection to the tractor electrical system. Signaling devices are connected with a separate wiring harness. At the rear of the unit are two lights.

On the video, the principle of operation of the RUM-5 fertilizer spreader using the example of the MVU-6 model:

For high income agriculture special equipment is required to reduce the cost of cultivating the soil and its top dressing. Fertilizers saturate a piece of land with various elements that increase soil fertility along with productivity and profit.

And if a small hand-held device is enough to disperse beneficial additives in a small area, then professional equipment is required for large productions.

What are mineral fertilizer spreaders

One of the most important and difficult tasks in the economy is to introduce fertilizers into the soil on time, quickly and in the right amount. It is extremely difficult to do this manually, so any farm owner needs to purchase at least one device for dispersing mineral fertilizers.

Among the large number of offers on the agricultural equipment market, it is easy to get confused not only for a beginner. After all, for specific tasks, equipment with specific technical characteristics is suitable.

Video: IRIS Double Disc Unit

Total exists two principles of dispersion of fertilizers and other mixtures:

• With pendulum tube
• When rotating discs with special blades

The first option is used only in small areas, because due to its technical limitations it is much inferior to the performance characteristics of mineral fertilizer disc spreaders.

According to the type of construction, solid organic fertilizer spreaders are divided into:

• Trailer. They are a container on wheels attached to the rear of the tractor.
• Mounted. Metal frame and hitch with brackets and hopper on top.
• Manual. Made in the form of a trolley with a small bunker, which must be pushed independently.

There are also self-propelled units, consisting of vehicle with attached equipment. This complex can replace several trailed spreaders of mineral fertilizers, but its cost is appropriate.

Advantages

With the help of automation of soil fertilization, you can achieve a more stable result than with manual processing of the field. And since it is necessary to saturate the land twice a year (in spring and autumn), a lot of time is saved in total, and the number of workers for servicing the farm is also reduced.

Precise dosing during spraying allows the fertilizer to be spread economically on the ground over large areas. With the help of a regulating system for the supply of raw materials, it is possible to distribute both several centners of fertilizers and a couple of tons on one piece of land.

The mineral fertilizer spreader copes well with sand, salt and seed. Such versatility makes it an indispensable thing even in the smallest household.

disadvantages

The first and most important disadvantage: great cost. And although this problem is not so urgent with manual diffuser options, automatic models can cost up to tens of thousands of dollars. The payback of such equipment can be delayed for several years. However, a simple version of the device can be assembled independently if dosage accuracy is not a decisive factor.

Moreover, mounted and trailed spreaders require tractors with a certain power, which will depend on the weight of the equipment attached to it and on the volume of fertilizers.

Safety

In no case should you be in the working area of ​​​​the device when it is working. It is necessary to study the operating instructions, as well as to study in detail the rules for using the equipment. All actions with the diffuser must be carried out only with the engine turned off.

Mounted models

Such mineral fertilizer spreaders are a metal or plastic hopper attached to the tractor with a special frame and brackets. They are compatible with tractors of any power, and at a relatively low price they perform their tasks perfectly.

Due to performance limitations, mounted fertilizer spreaders more commonly used for small areas. For large areas, it is worth paying attention to trailers.

Before buying, you need to make sure that the tractor hitch is compatible with the fertilizer spreader. Modern models of tractors should not have problems. However, the old Soviet equipment was developed according to different standards, and it will require the purchase of new attachment components.

Mounted disc spreader

This is a metal hopper with a frame, inside of which mechanical agitators (tedders) are located to evenly distribute the contents. A grate for sifting fertilizers is attached above them.

Under the bunker there is a control for the supply of bulk solids, consisting of a restrictive and shut-off valve. The first regulates the supply of fertilizers, the second - hermetically closes the container for ease of movement around the area. The shutters have locks that do not allow them to move arbitrarily during operation.

The contents of the container, under the influence of the agitator shaft, fall onto the rotating distribution plates, bypassing the shutters. Further, the blades intercept the fertilizers in small portions and, thanks to centrifugal force, scatter them evenly on the ground.

This creates a fertilizer strip behind the tractor. There can be one or more distribution plates, and they can work both together and separately. The blades are adjustable and replaceable for different tasks.

The rotation of all parts ensures the rotation of the power take-off shaft (PTO) of the tractor. Attached to it with brackets.

Pendulum Mounted Spreader

This device differs from the disk device only in a scattering device. Instead of rotating discs, a special oscillating tube made of durable plastic is used, which throws the contents onto the ground with a quick right-left movement.

This type of mineral fertilizer spreaders is much less common than disc type spreaders and is significantly inferior in terms of its characteristics. This is due to a design limitation: the vibration frequency of the tube cannot be increased significantly, which means the contents of the hopper will not be distributed evenly enough.

Moreover, if the oscillation frequency is set incorrectly, the device will fail and all drive components of the mechanism will have to be changed. Also, the device emits a sharp noise that cannot be drowned out by anything.

Due to the low productivity of the tube, the working speed of the tractor, on which the pendulum fertilizer spreader is hung, is reduced. Spreading width reaches up to 8 m, and the maximum performance of such a design is only 2 Ha/hour, which is clearly not enough for large areas.

Trailed spreaders

By and large, the principle of operation of this unit does not differ from mounted organic fertilizer spreaders. The only difference is that the towing devices are made in the form of a trailer on wheels, attached to the frame behind the tractor. However, the possibilities of such devices are wide.

Depending on the cost and specific model, trailed fertilizer spreaders can hold up to several tens of tons of fertilizer, and the working width extends to tens of meters.

And if the trailer has wide wheels, this allows you to work in the spring on damp soil and not depend on weather conditions. Such units significantly save mineral fertilizers, and are also often used as a manure spreader. This saves a lot of time and labor costs.

Manual models

This is the easiest and cheapest option on the market. The name speaks for itself: they have to be pushed in front of you across the field. And although uniformity and speed leave much to be desired, this type of fertilizer spreader is actively used in small areas and summer cottages.

After all, with their help, you can not only scatter fertilizers, but also sow various crops. In winter, such a unit will help scatter sand or salt on the paths.

The mechanism of the manual spreader is very simple: the disc with blades is driven from the wheels by means of a chain drive and cables. The amount of material to be spread is adjusted by a damper, which is adjusted by screws. To sift the contents, you can use the mesh while pouring the mixture into the container.

Homemade manual spreader

Any home craftsman can create a simple do-it-yourself fertilizer spreader. To do this, you need to take a suitable container, attach to it 2 running wheels.

In the bottom of the container, you need to make several holes and close them with homemade spreading plates with two blades each. Now it remains to attach the agitator to the container and make sure that the wheels set the whole mechanism in motion.

If you managed to find a cone, then you can cut off its top and attach it to the wheels down with a narrow part. Under the hole you need to put one disk with blades, which will rotate when moving.

As a damper, you can use a metal strip, which is fixed around the top of the cone and at the same time can change the vertical position between the cone and the disk. In this way, it is possible to adjust the width of the gap through which the contents of the cone will spill onto the disk and then onto the soil.

How to choose

To choose the best option for specific tasks, you must at least superficially know the performance characteristics.

• Capture width. This indicator indicates how wide a coverage strip will be created using a spreader. Directly affects productivity, because the wider the grip, the faster the field will be processed. Measured in meters.
• Bunker volume. The more fertilizer you can put in at once, the less often you have to interrupt work and reload the spreader. In addition, after a reboot, it will not be possible to spray fertilizer with exactly the same concentration as before.
• Weight of equipment with empty hopper.
• The frequency of rotation of disks and their number(if it is a disc spreader). European standard - 540 revolutions. All standard adjustments of modern spreaders are designed for them. Therefore, if it is different for the tractor, you will have to adjust the height rate manually. This will not be necessary if the tractor has the ability to change the PTO speed. Information about this is in passport.
• Tractor power in l. from. which is recommended for normal operation.
• Tractor models of the same brand which are ideal for the spreader. These are recommendations from the manufacturer, but it is not necessary to follow them if the tractor is already available or planned to be purchased from another brand.
• For which type of fertilizer equipment is intended: granules, powder, sand, salt, etc.
• Manufacturer, expiration date and warranty.

All modern models have spreading systems, be it discs or a pendulum tube, made of stainless steel, and the hopper is covered with a special powder paint that does not allow fertilizers to destroy metal.

Spreader control can be manual or automatic. In the first option, during the adjustment, you will have to turn off the engine and change, for example, the position of the dampers. Of course, doing this automatically is much more convenient, but the price is also higher.

Manufacturers

Among foreign manufacturers, German brands are especially valued, where quality and reliability issues are very carefully approached. Belarus also performed well, in particular, due to the low price and at the same time quite good quality.

Amazone

This is a family-owned German company that has existed for 4 generations. Now the company has 6 plants distributed throughout Europe, including Russia. Amazone values ​​​​its reputation very much, therefore it constantly improves its products and carefully monitors the quality of components.

Undoubtedly, the advent of technology in agricultural processes greatly simplifies many activities. The use of machines saves time and sometimes money. Modern industry produces various fertilizer spreaders, which are worth considering in more detail.

Appropriateness of application

During the cultivation of any agricultural product, fertilization is an important but very time-consuming process. Without regular top dressing, you will not be able to get a good harvest.

Fertilizing large areas is even more difficult, it takes a lot of time and effort. To facilitate the task, special fertilizer spreaders have been created. Their purpose is to minimize the participation of a person in this exhausting type of labor activity. These complex units manage to take on the bulk of the work, making life easier for farmers.

Varieties

Fertilizer spreaders are classified according to several parameters. First of all - by the type of elements added to the soil. That is, they can be intended for the introduction of mineral or organic components.

Fertilizer machines are classified according to their functions. They can help:

• mix;
• grind;
• transport fertilizer.

Fertilizer spreaders introduce top dressing into the soil in the following forms:

• dusty;
• in granules;
• manure compositions;
• liquid solutions.

Depending on the attachment features, such machines are:

1. Self-propelled. This technique works autonomously, does not require connection to other machines.
2. Trailed - they are attached to the tractor.
3. Semitrailer vehicles. They can be attached to machines or work independently.
4. Mounted. They hang themselves to other agricultural machines.
5. Manual type. These spreaders are suitable for small areas.

Manual type fertilizer spreaders are often made by farmers on their own. They are based on a cart or a wheelbarrow. And the technique works according to the centrifugal, pneumatic or pendulum type.

Advantages and disadvantages

Every technique has its pros and cons. The advantages of such units include:

• fast pace of delivery of nutritional formulations;
• ability to process vast territories;
• saving time when fertilizing;
• uniform coverage of the site with nutrient mixtures of large volumes;
• the introduction of compounds only during the movement of the unit;
• some models have a fertilizer adjustment function;
• the ability to use for other agricultural purposes - for example, for spreading seeds.

The disadvantages include the high cost of the units. Farmers who have small plots at their disposal prefer to create spreaders with their own hands.

For processing large areas, it is worth purchasing professional equipment in a specialized store. A variety of models allows you to choose the option necessary for the processing of a particular area. The cost of such equipment will pay off in a few years.

Consider the most popular manufacturers.
