Description

The utility model relates to the field of agriculture, in particular, to machines for cleaning weed impurities from a pile of grain materials, as well as loading of refined grain into vehicles and other technological equipment for further processing.

The closest in technical essence and technical result to the claimed device is a heap cleaner, a self-moving grain thrower, which contains a frame with driving and steering wheels and a self-moving mechanism, on which an electrically operated feed conveyor, a cleaning unit with a transport chute and the main discharge box for feeding are sequentially installed grain in the rotary trimmer, equipped with an electric drive (UA 115953; "Heap cleaner, self-moving grain thrower", A01F 12/44 ;; 05.05.2017].

The known device is made self-moving using the methods of block-modular construction, and the loading conveyor, grain cleaning unit and shipping trimmer are made in the form of autonomous replaceable modules.

An autonomous grain cleaning module performs grain cleaning and is equipped with a pneumo-separation system that removes light impurities from the dusty air stream.

A disadvantage of the known cleaner is that the pneumo-separation system of an autonomous grain cleaning module does not allow efficient removal of fine particles and dust from the dust-air stream, which are smaller than the grains of the main grain material, and have a larger specific gravity, which leads to clogging of the purified grain with such particles, reduces cleaning efficiency, requires further processing of the material using lattice machines, which limits the range of technological capabilities and that increases t damage the treated grain.

The technical challenge that the utility model is addressing is to increase the efficiency of removing small particles and dust from a dusty air stream and expanding the range of technological capabilities and reducing damage to the processed grain.

The technical problem is solved, and the technical result is achieved by using a self-movable grain thrower in the heap cleaner, which contains a frame with driving and steering wheels and a self-forwarding mechanism, on which an electrically operated feed conveyor has a grain cleaning unit with a transport chute and the main discharge box for feeding grain in the rotary trimmer, equipped with an electric drive according to the utility model, the main discharge box of the transport chute is tion comprises a changeover valve, wherein the conveying chute winnowing unit has an end section comprising an additional discharge duct, and the bottom front of the main discharge duct installed screening surface made in the form of lattice webs and to trash box.

Equipping the main unloading box of the transport chute with a flip valve and equipping the transport chute of the grain cleaning unit with an end section with an additional unloading box, as well as installing the bottom of the main unloading box of the screening surface, allows you to change the technological configuration of the machine and the process depending on the type grain crops, the state of the grain material and the requirements for refined grain and withdrawal from the technological separate chains, as well as allows to reduce the mechanical effect of moving parts of the device on the grain, which, in turn, reduces damage to the processed grain.

The presence of an inclined perforated surface of the transport chute of the grain-cleaning unit provides an increase in time and also the route of the grain over the surface of the sieves, which improves the quality of cleaning and removes more dust and trash that pass through the lattice screening surface under the influence of gravity impurities.

Thus, the proposed design solution allows to increase the efficiency of removing small dust particles from the dust-air flow, expand the range of technological capabilities and change the technological configuration of the machine and the process depending on the grain crops to be cleaned, the state of the grain material and the requirements for the cleaned grain.

In the future, the utility model is illustrated by an example of its implementation with reference to the drawings, which are attached.

FIG. Figure 1 shows a heap cleaner with a self-moving grain thrower with the shuttle valve open (general view).

FIG. Figure 2 shows a heap cleaner with a self-moving grain thrower with the check valve closed (general view).

The heap cleaner of the self-moving grain thrower (Fig. 1, 2) contains a frame 1 with leading 2 and steering 3 wheels, and is equipped with a self-forwarding mechanism 4 for moving and maneuvering.

On the frame there are consistently installed a loading conveyor 5, which is driven by an electric drive 6, a grain cleaning unit 7 with a transport chute 8, equipped with a main discharge box 9 for feeding grain to the rotary trimmer 10, which in turn is equipped with an electric drive 11.

The main discharge duct 9 of the transport chute 8 contains a reversing valve 12, the transport chute 8 of the grain cleaning unit 7 being elongated and having an end section 13 containing an additional discharge duct 14 for feeding grain to a vehicle, or to a storage area with an angular rotation of the trimmer 10 in the horizontal plane.

Bottom in front of the main discharge box 9 installed screening surface 15, made in the form of lattice paintings, and the box 16 for collecting trash.

Works heap cleaner self-moving grain thrower as follows.

The loading conveyor 5, which is driven by electric drive 6, delivers grain material to the grain cleaning unit 7, where with the help of mechanical means the grain is cleaned from large trash, and the air separation system removes light impurities and fine dust from the air-dust flow.

For unloading the cleaned grain from the grain cleaning unit 7 and after-treatment it is equipped with a transport chute 8 with a screening surface 15.

Grain material on an inclined transport chute 8 moves along a perforated screening surface 15, while coarse dust and small heavy impurities, passing through the sieve cells, are removed from the grain flow and fall into the duct 16 and are removed outside.

When the flap valve 12 is open (Fig. 1), the cleaned grain, which is flowed along the inclined chute 8, under the action of its weight, wakes up into the main discharge box 9, and then into the receiving neck of the trimmer 10, which is driven by the electric drive 11. Next, the cleaned grain the trimmer 10 is sent to the vehicle, or to the storage area for further storage.

When the reversing valve 12 is closed (Fig. 2), the grain is transported along the inclined chute 8 and its final section 13, bypassing the trimmer 10 to the additional discharge box 14, from where it is dumped to the working platform of the warehouse or to the means of transport. At the same time, the trimmer 10 is removed from the process, rotates to any of the sides from the axis of the cleaner of the heap of the self-moving zirnometa and does not interfere with the operation of the cleaner in the mode of saving load and energy saving.

Self-movement and maneuverability of the cleaner of the heap of the self-moving zernometatel is provided with the help of the leading and steering wheels 2 and 3, and the self-movement mechanism 4.

Thus, due to the equipment of the cleaner of the self-moving grain thrower with an additional system for cleaning the grain material and shipment of the grain material, it is possible, depending on the type of grain material and technical capabilities and needs of a particular farm, to significantly improve the processability of the cleaner, especially when working with hardly separable impurities, largely eliminate the mechanical effect of moving parts on the grain, which helps to prevent them from Possible injury.

Thus, the implementation of a flexible technological scheme in the design of a heap of a self-moving zernometa of a flexible technological circuit makes it possible to significantly reduce the damage to the grains and improve the sowing properties of seed material.

In addition, the exclusion from the technological chain of individual mechanisms can significantly reduce energy consumption.

The proposed cleaner of the pile of self-moving grain thrower can be widely used in the field of agriculture, in particular, in the production and use of machines for cleaning off trash of heaps of harvested grain materials, has industrial applicability, improves the cleaning efficiency of the grain material and can be implemented industrially on any an enterprise for the manufacture of agricultural machinery using standard technologies, components and components.
