Anyone close to Earth knows that without mineral fertilizers do not see high yields. Observing the necessary proportions of their introduction, you can get excellent results and good revenues from the sale of our products. The RM-5 aggregate, called the fertilizer spreader, will help quickly and accurately distribute them along the field.

Make this device since 1985 in the city of Neftekamsk, at the enterprise Bashxelmash. The more modern name is MBU-5. Factory designers have developed an aggregate, very similar to a popular spreader 1-RMG-4. The differences of the new machine sticking to the MTZ-80 were the operation of all mechanisms from the tractor shaft of the power take-off, as well as the chassis made by the Tandem type. The design over time has become more perfect, but no indigenous changes have undergone.

Purpose

With this unit, it is possible to fertilize the land with solids of various densities in the form of powder, granules or crystals. In particular, it can be ammonia nitrate, superphosphate, potash salt, dolomite and lime flour, other fertilizers. They can be made in the soil in spring or autumn, as well as to spend the summer feeding of intensively growing grain.

It is possible in all regions other than the highlands. With it, it is scattered and transported not only fertilizers, but also sand, lime, various chemicals in bulk condition.

Advantages and disadvantages

Advantages:

• Easy adjustment of the unit, easy to use.
• Adjusting the dose of fertilizer making the height of the rapid gap. In the instructions for the machine are given this data for each type of fertilizer.
• It is possible to scatter useful substances both along the entire width of the field, and only on the edges or in the middle.
• The presence of a mechanism that ensures maximum uniformity of feeding along the entire width (up to the maximum).

Disadvantages:

• Compared to mounted spreaders equipped with a very accurate dosage system, the uniformity of work is somewhat lower.
• No ability to move on your own - you need a tractor.

Device

Metal frame is equipped with breathing and loop for attaching to the tractor. The five-ton welded body where fertilizers are falling asleep, is part of the frame. Inside the body is a plate-rod-type conveyor. It leads to a movement either the tractor shaft of the power take-off (if the fertilizer is made more than six tons per hectare), or (with a smaller number of fertilizers) shaft inside the half-axis rear wheelchair.

The conveyor supplies a rash mass on the sowing discs of a centrifugal type, each of which is equipped with four blades with grooves, fixed perpendicular to each other. Movement on them comes from the tractor B. Cardan, conical type gearboxes, clinorem-type profiles and satellite shafts are involved in the transmission.

To fertilizers fade more evenly, there is a bimetallic paculent shield installed on onboard supports. Dosing Sewber, moving around the clamps in the back of the body, is controlled by the helmet installed on the shaft. Two stars engaged with slats allow you to adjust the flap height.

The chassis is a cart with balancing, designed by Tandem type and not having a springs. The wheel of the detachable type is six stiletto and nuts attached to the hub on which there is a drum for braking. The brakes of the unit are two types: mechanical (intended for braking in the parking lot) and pneumatic, single-wire. The latter is controlled from the tractor cabin, pedal. You can manually brake with a crane. The front wheels stop.

To connect to the tractor electrical system there is a plug. Separate wiring harness is connected to alarm device. In the back of the unit there are two lamp.

In the video, the principle of operation of the RM-5 fertilizer spreader on the example of the MBU-6 model:

MBU-5 fertilizer spreader is a semi-trailed unit for making bulk mineral fertilizers. Machine for making the MBU-5 fertilizer has the following design features: the running part of the MBU-5 machine is a lonely balancing trolley of the tandem type, consisting of two balancing connected by the central axis on the sliding bearings, with axes for fastening the wheels. Inside the body there is a device for uniform unloading fertilizers, which is a volumetric screen from a bimetal installed on two supports fixed on the front and side sides.
The dosing valve of an improved design is a Sewber moving in the guides on board the body using the helmet fixed on the shaft together with two asterisks, which are engaged in engaging with the flashers on the flap.
The rod-plate conveyor machine consists of straight rods connected into a closed circuit with a link plates. The drive of the conveyor with doses of making up to 6000 kg / ha is carried out from the move wheels, over 6000 from the tractor B.

Scattering discs have four groove blades installed at an angle of 900 each other. To increase the strength, the discs are equipped with eccentrics and annular corrugations. The drive of the disks is carried out from the tractor B through the drive shaft, intermediate shafts, two clinorem contours and two conical gearboxes.

Fertilization rateadjusted by changing the size of the slot over the conveyor using the flap on the rear wall of the body. The size of the slot for different types of fertilizers and the rate of application is taken from the table in the instructions for the machine and placed on a metal plate on the back board of the spreader body.

The fertilization rate is also regulated by changing the transfer ratio of the feed transport drive mechanism by rearranging the drive chain to the appropriate pairs of spars.

Uniformity of the distribution of fertilizersin the width of the capture is governed by the movement of the punching agent according to its guide and change of the position of moving wall-dividers.

Moving the PECTOR forward in the course of the spreader leads to changing the fertilizer feed location closer to the periphery of the disks. This causes a decrease in the initial velocity of the fertilizer particles from the disks, which makes it possible to increase their concentration in the middle part of the sowing strip.

The movement of the Packover in the opposite direction entails the displacement of the Fertilizer's feed location closer to the disk centers, therefore, to an increase in the initial velocity of the particle waste, which allows to increase the concentration of fertilizers along the edges of the sowing strip.

The same effect can be obtained by turning the moving walls-divisors to the centers of scattering disks, and the opposite direction.

Power conveyor belt tension Regulated by moving its slave shaft using special screws. At the same time, the rods of the conveyor must lay down to the floor of the body, and at the bottom there is an arrow of the deflection to 10 mm. Before adjustment, it is necessary to thoroughly clean the stream of the floor of the body from fertilizers. When performing adjustment, it is necessary to ensure that the tension of the branches is the same. Especially carefully needed to monitor the correct adjustment of the conveyor in the first 30 ... 50 hours of operation, when its intensive extract and the guard occurs

The width of the sprawler capture is 6-14 m, depending on the acclaimed fertilizers and weather conditions. With the windproof device, the width of the capture is 6m. The spreader with class 14-kn tractors, equipped with hydrocruines and plug connectors for connecting electrical equipment, is aggregated.

When preparations for the operation of the tractor with the MBU-5 spreader set 1800 mm. Check the pressure in the tires of the spreader wheels and, if necessary, adjust it to a nominal - 0.35 MPa.

Connect the spreader with a tractor hydrochryuk, lifted and fixed in the upper position. Installation chains and electrical equipment of the tractor and spreader.

Before testing the machine in motion, the dosing flap is raised so that the conveyor freely passed under the flap, the bottom of the body is cleaned of fertilizers. After that, adjust the tension of the conveyor, moving the slave shaft by tensioning screws. The tension is considered normal if its lower branch is barely concerned. Excessive tension of the conveyor leads to intensive wear. Disament of the conveyor and the presence of curved units are not allowed.

For the introduction of solid mineral fertilizers, in addition to the MBU-5 spreader, the industry produces similar to it on the device and technological process of the machine1-RMG-4, MWU-8 and MWU-16 with a carrying capacity, respectively, 4, 10 and 6 tons. They are aggregated with MTZ-80 tractors , T-150K These design spreaders differ from MBU-5 by the fact that the drive of the supply conveyors they produce from the move wheels.

MBU-8 spreader

MBU-8 spreader differs from MBU-5 spreader with a larger lifting capacity and construct of the chassis. The chassis is uniaxial with a compound of a pair of right and left wheels according to the Tandem scheme. Such a design provides a smooth move of the spreader on the irregularities of the field.

The feeder conveyor is activated from the rear right wheel through the cardan shaft and chain gears. The drive shaft during the operation of the spreader is connected to the axis of the chassis with the coupling, driven by the tractor hydraulic system. At the ends of the gons, this drive is turned off.

The MBU-8 spreading disk drive is carried out from the Tractor's power take-off (VOM) shaft through the drive shaft, the clinorem and conical gearboxes, on the slave shafts of which they are fixed.

The mechanisms for the installation of a given norm of making and adjusting the uniform distribution of fertilizers along the surface of the field are not different from the design of the corresponding nodes on the spreader 1 -rmg-4, and the order of their adjustment is the same.

In the case of the use of MBU-type spreaders on the carriage of bulk materials, scattering discs are removed, the feeding conveyor drive is carried out from a tractor in a tractor, which allows you to unload the detailed material when the unit is stopped.

performs surface (solid) introduction of mineral fertilizers, their mixtures and weak limestone materials.

The unit of the unit includes:

• Body;
• Running part;
• Conveyor;
• Drive of the working bodies;
• Dosage damper;
• Sweat;
• Scattering discs;
• Electrical equipment.

All-metal welded body MAV-6 machine, the design of which is a flat bottom and four inclined boards, serves as the basis for the establishment of working bodies and auxiliary elements. The rear side of the unit is equipped with a window designed to feed the loaded material from the body. The dosing flap, mechanically moving up-down, changes the height of the window in order to regulate the dose of material for dispersion. The front side of the body has a window to control the discharge process. The bottom of the body in front of the stubble is the form of a tray that prevents ripple when the small dose conveyor is served. The touchener, which consists of two removable tray and the flow divider, performs the separation of the stream into two uniform parts. When permuting the mounting bolts on the trays into the holes A, B and B, the direction of scattering the feed material is changed and the necessary uniformity is ensured. In the process of making granular fertilizers, the dispersion bandwidth reaches 20 meters, crystalline and weak meliorants - 10 meters. The base base for this unit is class 1.4 and 2 tractors, with the frequency of rotation of the power selection shaft of a thousand revolutions per minute and connectors for connecting the electrical unit.

MAK MAV-6

Designed for transportation and residence on the surface of the soil of mineral fertilizers and weak limestone materials. The machine is a uniaxial semi-trailer, on the frame of which the body 2 is mounted (Fig. III.5, a), dishoning the apparatus 4, tuktonitor 5, mechanisms and transmission.

The all-metal welded body has an inclined side and a flat bottom, which moves the upper branch of the chain-plate conveyor 7. The conveyor will go with chains on the brief and rollers of the slave shaft and drives from the chain drive 3 or from the tractor in the transmission reducer and chain Drive 3. When making fertilizers at a dose

200 ... 2000 kg / hectares use the first drive variant, and when Meliorants are introduced at a dose of 1000 ... 10 000 kg / ha - the second option. Switching transmission from the first version to the second and back is the turn of the gear lever located on the left side of the machine, to "Enabled" or "off". In the back of the body, a window 8 is cut out for feeding the fertilizer from the body to the dyeing machine 4. To change the height of the window and regulate this dose of fertilizer, the valve 9 is shown, which the mechanism 10 is moved up-down.

The PECTOR 5 serves to divide the flow of fertilizer into two equal parts. It consists of a flow divider 11 (Fig. III.5, b) and two removable trays 12. Rearming the mounting bolts in the holes A, B and B, change the slope of the trays and the place of receipt of fertilizer on the discs.

The screaming device is equipped with two discs 14, on the surface of which blades are fixed 13. The discs are fixed on vertical shafts of gearboxes 6 and are rotated from the tractor.

The working process. Fertilizers are loaded in the body with a loader, go to the field and include transfer to the feeder conveyor and discs. When the machine moves along the field, the border conveyor moves out of the body a layer of fertilizer, in thickness equal to the height of the window, and resets them with a continuous stream perintener. Encatarating into two streams, fertilizers come to rotating discs, they are fond of them in rotation and spread through the band by the bandwidth of BP (Fig. III.5, B).

Adjustments. For aggregation with MBU-6, the tractor set the necessary frequency of rotation of the VOM (1000 minutes' "). The table is chosen the position of the flap for a given dose of fertilizer and rotation of the steering wheel 10 (see Fig. III.5, a) combine the edge of the damper with the corresponding The division number of the scale. The uniformity of the distribution of fertilizers in the width of the RVR (see Fig. III.5, B) depends on the tilt of the trays and the location on the zone disks in which fertilizers come in. Rearing trays in the holes A (see Fig. III.5 , B), B and B, change the direction of sieving fertilizers and achieve the necessary uniformity. If the trays are fixed in the hole A, then the concentration of fertilizers in the middle of the rieving band is increasing, if in the opening in its edges.
