Machine MVU-6
It is intended for transportation and sieving of mineral fertilizers and low-dusting calcareous materials on the soil surface. The machine is a single-axle semi-trailer, on the frame of which a body 2 (Fig. III.5, a), a sieving apparatus 4, a fertilizer guide 5, mechanisms and gears are mounted.
The all-metal welded body has sloping sides and a flat bottom, along which the upper branch of the chain-slat conveyor 7 moves. drive 3. When fertilizing in a dose
200...2000 kg/ha, the first drive option is used, and when ameliorants are applied at a dose of 1000...10,000 kg/ha, the second option is used. Gear shifting from the first option to the second and vice versa is carried out by turning the gear lever located on the left on the machine frame to the “On” or “Off” position. A window 8 is cut out in the rear wall of the body for supplying fertilizers from the body to the sieving device 4. To change the height of the window and regulate the dose of fertilizers, a damper 9 is used, which is moved up and down by the mechanism 10.
The fertilizer guide 5 serves to divide the flow of fertilizers into two equal parts. It consists of a flow divider 11 (Fig. III.5, b) and two removable trays 12. By rearranging the mounting bolts in holes A, B and C, the slope of the trays and the place where fertilizers enter the disks are changed.
The sieving device is equipped with two disks 14, on the surface of which the blades 13 are fixed. The disks are fixed on the vertical shafts of the gearboxes 6 and are driven by the tractor PTO.
The working process. Fertilizers are loaded into the body with a loader, go to the field and turn on the transfer to the conveyor-feeder and disks. When the machine moves across the field, the bar conveyor moves a layer of fertilizer from the body, equal in thickness to the height of the window, and dumps them in a continuous stream onto the fertilizer guide divider. Divided into two streams, fertilizers enter the rotating disks, are carried away by them into rotation and are scattered across the field with a strip of width Bp (Fig. III.5, c).
Adjustments. For aggregation with MVU-6 on the tractor, set the required PTO speed (1000 min '"). According to the table, select the position of the damper for a given dose of fertilizer application and rotate the steering wheel 10 (see Fig. III.5, a) align the edge of the damper with the corresponding number of division of the scale Uniform distribution of fertilizers across the sieving width Вр (see Fig. III.5, c) depends on the inclination of the trays and the location on the disks of the zone into which the fertilizers enter. , b), B and C, change the direction of fertilizer sieving and achieve the necessary uniformity.If the trays are fixed in hole A, then the concentration of fertilizers in the middle of the sieving strip increases, if in hole C - along its edges.

Machine for application of mineral fertilizers MVU-6
The MVU-6 machine is designed for transportation and surface continuous application of mineral fertilizers and low-dust calcareous materials into the soil in soil-climatic zones: Russian Federation, Ukraine, Belarus, Baltic States, North Caucasus, Urals, Siberia, Kazakhstan, Moldova.
The machine is aggregated with a tractor of traction classes 1.4 ... 2 (MTZ-80, MTZ-82), equipped with a hydroficated traction hook, a rear power take-off shaft with a rotation speed of 1000 rpm, outlets for connecting electrical equipment, hydraulic and pneumatic brake systems. Serves her tractor driver.
Device
The MVU-6 machine (Fig. 1) is a semi-trailer equipped with a transporting and two dissipating centrifugal-type working bodies.
Rice. 1 The device of the machine MVU-6: 1- body; 2- ladder; 3- lanterns; 4- cardan shaft; 5- coupling device; 6- support; 7- hand brake handle; 8- receiver; 9- running system; 10- drive conveyor-feeder; 11-dispersive discs; 12- bumper; 13-reflectors
The body of the machine is metal, all-welded construction, consists of sides and a frame. To access it, a ladder is used, which in the transport position is installed in brackets on board.
The fertilizer guide includes a flow divider and two trays, which, depending on their installation (three positions), can redistribute the material supply across the width of the sowing strip.
The feeder conveyor and spreading discs are driven from the tractor PTO or separately (feeder conveyor from the running wheel of the machine, spreading discs from the tractor PTO). The tension of the conveyor-feeder is carried out by moving the spring-loaded axis with the help of bolts.
The machine has two brake drives independent of each other: pneumatic, acting from the tractor pneumatic system, and mechanical manual. The pneumatic brake drive serves to brake the machine and the tractor simultaneously in motion and when stopped, and is activated when the tractor brake pedal is pressed. The manual mechanical drive of the brakes serves to brake the machine in the parking lot (parking brake). Braking is done by turning the handle clockwise, releasing - against.
The electrical equipment system includes two front and rear lights, a license plate light and a wiring harness for supplying power from the tractor's mains.
The principle of operation of the machine is as follows: fertilizer (applied material) is fed by a conveyor-feeder from the body of the machine through a dosing gate and a fertilizer guide to disks that disperse it in a fan-shaped flow over the soil surface (Fig. 2)
Operating procedure
Prepared mineral fertilizers (lime, gypsum-containing materials) are loaded into the car body by loading means. Before starting work, the required dose of application is set. Depending on the type and dose of the applied material, the setting is reduced to adjusting the height of the seed slot of the metering gate, installing the fertilizer guide trays and ensuring the drive of the conveyor-feeder from the tractor PTO or the machine wheel.
The opening of the metering gate for a given dose of application is carried out by rotating the handwheel using a rack and pinion mechanism.
The uniformity of the distribution of materials (fertilizers) on the application strip is determined visually and is regulated by the installation of trays. When applying granular and fine-grained mineral fertilizers, adjustable trays are installed on the divider, allowing you to change the place of supply of the mass to the sieving discs. If they are installed along hole 1, then the concentration of applied fertilizers increases in the middle part of the sown strip, if they are installed along hole 3 - along the edges of the sown strip.
Estimated doses of application at the appropriate bulk density, working width of sieving and forward speed of the unit are shown in the tables depending on the drive of the conveyor-feeder.
Maintenance
The reliability of the machine depends on the correct and timely implementation of measures for its maintenance. During operation, the following types of maintenance are carried out:
during running-in, preparation for running-in and its completion;
ETO every 10 hours of work;
TO-1 after 60 hours of work under load;
During inter-shift short-term and long-term storage;
Maintenance before the start of the maintenance season.
When carrying out ETO, it is necessary to clean the machine from dirt and residues of the materials introduced, rinse it with warm water, check the completeness and correctness of its aggregation with the tractor, the tension of the feeder conveyor and the operation of the brakes; you should also make sure that the electrical equipment is working and check the tightness of the connections of the hydraulic and pneumatic brake systems.
During TO-1, all activities for shift maintenance are carried out, and additionally, the reliability of fastening of wheel gearboxes, dispersing disks, housings and bearing caps, body to the axle of the balancing bogie, as well as the pressure in the tires of the wheels are checked.
When installing the machine for long-term storage, it is washed, an external inspection is carried out, it is thoroughly cleaned of rust and the damaged color is restored; unpainted surfaces are coated with anti-corrosion grease; plugs are put on the outlets of the pipelines, the tension bolts of the feeder conveyor are loosened. After that, the machine is installed on the storage platform and lubricated.
Security measures
When running in and operating the machine, before starting work, it is necessary to inspect the fastenings of the main assembly units, check the presence of guards, protective covers and the tension of the feeder conveyor.
Before turning on the drive of the working bodies, the tractor driver must give warning signal and check the position of the levers for engaging the power take-off shaft and the gearbox, which should be in the neutral position.
Changing wheels, adjusting wheel hub bearings, and adjusting brakes should be done with safety stands installed under the balancers. It is forbidden to transport people in the body of the machine, repair and maintenance with the tractor engine running, driving across the field at a speed of more than 24 km/h, the presence of people in the area of the running machine (closer than 25 m), work without personal protective equipment, with a faulty brake system and light signaling.
performs surface (continuous) application of mineral fertilizers, their mixtures and low-dust calcareous materials.
The device of the unit includes:
- Body;
- Chassis;
- Conveyor;
- Drive of working bodies;
- dosing valve;
- straightener;
- Scattering discs;
- Electrical equipment.
The all-metal welded body of the MVU-6 machine, the design of which is a flat bottom and four inclined sides, serves as the basis for the installation of working bodies and auxiliary elements. The back board of the unit is equipped with the window intended for supply of the loaded material from a body. The dosing damper, which moves mechanically up and down, changes the height of the window in order to regulate the dose of material to be dispersed. The front side of the body has a window to control the unloading process. The bottom of the body in front of the fertilizer straightener has the shape of a tray that prevents pulsations when small doses are supplied by the conveyor. The fertilizer guide, which includes two removable trays and a flow divider, divides the flow into two equal parts. When rearranging the fastening bolts on the trays in holes A, B and C, the direction of dispersion of the supplied material changes and the necessary uniformity is ensured. In the process of applying granular fertilizers, the width of the scattering band reaches 20 meters, crystalline and low-dust ameliorants - 10 meters. The basic basis for this unit is tractors of class 1.4 and 2, with a power take-off speed of one thousand revolutions per minute and connectors for connecting electrical equipment.
