Description

The device is designed to move grain or corn from ground storage areas to cars, conveyors and other receivers in an oblique direction and can be used for work in warehouses and granaries, food production.

A device is known comprising a bucket conveyor mounted obliquely on a self-propelled truck (see _zernopogruzchiki_g1050986)

A known device, such as grain loader R6 KShP 6 M self-propelled bucket auger. The device is designed for loading grain and corn on the cob from ground storage areas into cars, onto conveyors and other receivers, and can also be used to move grain and work inside warehouses. The known device consists of a bucket conveyor with pick-up screws that are installed in a common bucket on both sides of the bucket conveyor, and the common bucket is a feeder for the bucket conveyor. The device is mounted on a self-propelled cart. The device has a complex structure, which does not exclude injury to the grain when it is moved from the pile into vehicles to conveyors and other receivers. At the same time, a ground clearance is inevitably formed between the lower edge of the common feeder bucket, which forms a layer of grain under the device, this layer is injured under the wheels of the device itself and the wheels of the vehicles into which it loads the grain. Loss of grain can be up to 10%.

The aim of the improvement is to eliminate grain losses during the selection of grain from the floor when moving it from the pile with a ladle conveyor.

The aforementioned goal is achieved in that a grain picker comprising a ladle conveyor inclined on a self-propelled truck, characterized in that at least one row of longitudinal panicle brushes is installed on the outside of the ladle conveyor along the free wall between the bottom and the front edge of each bucket.

Effect: the buckets in the lower part of the conveyor during the translational movement of the self-propelled cart into the shoulder with the leading edge scoop up grain, which partially fills their cavity and moves together with the buckets along an inclined path upward. At the same time, panicle brushes at the same time as scooping the grain with buckets sweep it again into the shoulder, which eliminates the loss of grain under the wheels of the cart and vehicles onto which the grain is transported using a conveyor. The grain is gently sweeping with panicle brushes and is not injured, which is important for its viability and subsequent storage. The proposed device directly draws grain from the shoulder, while also returns the grain that has spilled onto the floor from the buckets and returns it to the pile with brushes and panicles, leaving no layer of grain behind.

In an alternative embodiment of the grain picker, the bucket conveyor is designed so that at least two adjacent buckets in the lower part of the bucket conveyor are able to move in parallel along the floor.

Technical result: in the case when the bucket conveyor is made in such a way that at least two adjacent buckets in the lower part of the bucket conveyor are able to move parallel along the floor, a more careful selection or sweeping of the grain from the floor to the pile with brush-whisks, which sequentially, moving one after another, more thoroughly sweep the floor and send the grain back to the pile for reloading into the conveyor buckets. The grain is gently swept sequentially by brushes with panicles and is not injured, which is important for its viability and subsequent storage using grain-sparing technology.

The design of the proposed device is presented in the drawings.

The Fadeev grain picker contains a bucket conveyor 2 mounted obliquely on a self-propelled truck 1, at least one row of longitudinal panicle brushes 4, which are designed to operate the device for sweeping a layer of grain 6 from under the buckets that spilled onto the floor 5 back into the pile, which eliminates the loss of grain 6 when loading it with a ladle conveyor 2.

The bucket conveyor 2 is made frontal and wide, can be tilted relative to the lower part to the horizon at an angle of 45 degrees towards the trolley 1. The horizontal projection of the upper part of the bucket conveyor 2 stands for the horizontal projection of the trolley 1.

In an alternative embodiment of the proposed device, the bucket conveyor 2 is made in such a way that at least two adjacent buckets 3 in the lower part of the bucket conveyor 2 are able to move parallel along the floor 5 so that the brush-panicles 4 on the buckets 3 are able to sweep the floor 5.

The width of the bucket conveyor 2 is 1800 mm.

The height of the discharge of grain 6 is from 4000 mm

The technical productivity of moving grain 6 is from 5 m ³ / hour. The speed of movement of the trolley 1 is from 0.1 m / s.

The speed of movement of the canvas with buckets 3 is up to 0.7 m / s, which ensures complete preservation of grain in contact with the bucket.

All four wheels 7 of the cart 1 of the grain picker 6 are autonomous, that is, they can rotate independently of each other.

Two front wheels 7 are self-rotating and their angle of rotation depends on the movement of two rear wheels 7 (not shown in the drawings).

Two rear wheels 7 are driven and have the ability to simultaneously rotate for the linear movement of the trolley 1 or to alternately rotate each of the two rear wheels 7, which allows the trolley 1 to move along the floor 5 with a left or right rotation by braking one of the two rear wheels 7 and rotating the other.

Each rear wheel 7 is equipped with an electric drive in the form of a gear motor.

The electric drives of the proposed device are controlled remotely from a portable control panel and have the ability to work in automatic or manual control modes by one operator.

The speed of movement of the trolley 1 and the movement of the bucket conveyor 2 can be varied by changing the frequency of the alternating current supply of the corresponding electric drives from the remote portable control panel.

The bucket conveyor 2 is a closed web enveloping the drive and tension drums (sprockets) and buckets 3 attached to the web. At the same time, there is at least one spacer element 8 between the web and the buckets 3, which moves the bucket wall 3 away from the web and This prevents injury to the grain 6 by buckets 3 on the canvas when the web is moving with the grain 6 loaded by buckets 3.

In the case of the execution of the chain traction unit, the buckets 3 are fixed by their side walls to the two traction chains.

In the bucket conveyor 2, a screw or load web tensioner is used.

As the traction unit of the bucket conveyor 2, a rubber conveyor belt or chain can be used.

Bucket conveyor 2 low-speed with 3 buckets with a rounded bottom.

To eliminate deformation during operation of the buckets 3, the longitudinal opposite edges of each bucket 3 are connected by at least one jumper or partition. In a specific example, there are three of them.

The electric drive of the bucket conveyor 2 has an asynchronous three-phase electric motor, gearbox and stop, preventing the reverse movement of the blade.

The proposed device operates as follows.

When moving grain 6 with a bucket conveyor 2 on a self-propelled cart 1 upward in an inclined direction from ground storage areas to cars, onto conveyors and other receivers, then panicle brushes 4, which are installed in one row or more outside along the free wall between the bottom and the leading edge each bucket 3 have the opportunity to sweep again into the pile the grain 6 that has woken up from the buckets 3 onto the floor 5 for reloading it into the buckets 3 and then moving it with the ladle conveyor 2.

The buckets 3 in the lower part of the conveyor 2 during the translational movement of the self-propelled cart 1 into the shoulder, the front edge scoops grain 6, which partially fills their cavity and moves together with the buckets 3 along an inclined path upward. At the same time, panicle brushes 4 simultaneously with scoops scooping 3 grains 6 sweep it from the floor 5 again to the shoulder, which eliminates the loss of grain 6 under the wheels 7 of the truck 1 and vehicles, which move the grain 6 using the conveyor 2. Grain 6 is gently sweeping with floor 5 with 4 panicle brushes and is not injured, which is important for its viability and subsequent storage.

In the case when the bucket conveyor 2 is made in such a way that at least two adjacent buckets 3 in the lower part of the bucket conveyor 2 are able to move in parallel along the floor 5, a more careful selection of grain 6 by brush-panicles 4, which are sequentially one after another they send grain 6 to the shoulder.
