Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery. The purpose of the invention is to improve the performance of the loader and reduce material loss. The loader contains a chassis, bunker, conveyor and dispenser. The dispenser is made in the form of a container from telescopically articulated parts 6, 7 fixed in a certain position by clamps 16 and divided into compartments 8, 9. Extreme compartments 8 are below the middle compartments, their walls are connected by plates 17. Material is held in compartments by flaps 10 with clamps 11. The dosing of the material is ensured by the fact that its surplus from the middle compartments is poured over the plates 17 into the extreme compartments, and after they are filled through the bypass windows 15. At this moment the supply of material is stopped. To load the machine, the unloading parts of the compartments are placed above the loadable containers, turning the handle through the cables simultaneously opens all the shutters 10 and all the loaded containers are filled with the necessary amount of material. The initial (closed) position of the shutter 10 is returned by a spring-loaded mechanism 14. 1 h. n. f-ly, 3 ill. (C (L

The invention relates to agricultural machinery, in particular to loading machines for agricultural machines and bulk materials.

The purpose of the invention is to increase the performance of the loader and reduce material loss.

FIG. 1 shows a diagram of the loader of agricultural machines, side view; in fig. 2 - dispenser, front view, section; in fig. 3 - the same, top view.

The proposed loader consists of a chassis 1 with a frame 2 on which a hopper 3 and a conveyor 4 are installed, under the discharge end of which a dispenser 5 is installed. The capacity of the dispenser 5 has a lower fixed 6 and an upper movable 7 part, separated by walls into compartments. The movable part 7 has compartments 8 with through cavities that are telescopically connected to the compartments 9 of the lower part of the dispenser. In the lower part of the compartments 9, the flaps 10 are hinged. and clips 11 valves. The clamps 11 are made in the form of two-arm levers connected by, for example, hinge bars 12 to the handle 13 of the control. The flaps 10 are spring-loaded from below with the aid of the mechanism 14, which serves it for the movable rod and the spring (not indicated). In the walls of the upper movable part of the container of the dispenser 5, there are made bypass windows 15 located at the level of the upper edges of the extreme compartments 8, which are located below the upper edges of the middle compartments 8. The telescopic connection of the compartments 8 and 9 is provided with clamps 16, for example, in the form of locking bolts. The cavities of the adjacent compartments are interconnected by plates 17 arranged at an angle to the horizon.

The loader works as follows.

The chassis 1 in an aggregate with a vehicle, for example a wheeled tractor (not shown), mounted on frame 2 and filled with, for example, granulated mineral fertilizers, bunker 3, leaves the field where cultivators work, for example. At the edge of the floor, the driver stops the vehicle, activates the conveyor 4, for example, by transferring from the tractor's PTO (not shown), which transports mineral fertilizers from the hopper 3, fills the dispenser 5. At the same time, the fertilizer is fed from above to the middle of the upper the movable part 7 of the dispenser tank. After filling the middle compartments, the fertilizers will begin to pour in the guides of the astians 17 into the extreme compartments, the upper edges of which are located below the upper edges of the middle compartments. After filling the extreme compartments, the fertilizer will begin to pour through the overflow ports 15. At this point the driver (the driver) turns off the drive (not shown) of the conveyor and the material supply (fertilizer) stops. Loss of fertilizer spilled through

the bypass ports 15 are excluded because they fall on the pallet (not indicated) of the dispenser 5, from where they are removed as they accumulate, for example, during the filling of the hopper 3 After filling the dispenser 5, regardless of whether the conveyor 4 is on or off, the amount of fertilizer in each compartment is equal to the total volume of the cavities of the upper and lower compartments, adjusted by telescopic connection of compartments fixed in a certain position with the help of clamps 16, in strict accordance with the volume of the loaded container, which is equal, for example measures for cultivator KHU- 4 0.075 m1

The fertilizers are kept in the compartments by means of the flaps 10, which in turn are held in the closed position by locks I. In this position, the loader either waits for the agricultural machine (cultivator) to enter, or approaches it. The cultivator is positioned relative to the loader so that each compartment of the device (metering unit) 5 is located above one of the loaded containers. In this position, the tractor operator turns the handle 13 of the control through the system and the gt 12 rotates the fasteners 11, releasing the shutter 10. Under the weight of the fertilizer, the shutter 10 opens and the fertilizer from the compartments of the dispenser 5 collapses into the container of the loaded cultivator (not shown) almost instantly. At the same time, losses of fertilizers are excluded, because the volume of each compartment does not exceed the volume of the loaded capacity. After emptying the metering device 5 under. the action of the springs of the mechanisms 14 of the valve 10 is returned to its original (closed) position. The cultivator loaded with fertilizers; the car departs and continues to work, and the tractor driver (driver) of the loader rotates the knobs 13 through the hinge system; is.

The proposed loader provides an increase in its performance when loading agricultural machines and allows reducing the loss of the loaded material.
