Description

one

The invention relates to the field of Agricultural Machinery, in particular to devices for threshing and separation of agricultural crops.

Known threshing and separating devices, including roller feeder, a series of blade beaters, located above the MOBILE deck, made in the in-pde endless conveyor mites and pneumocharger installed on the output.

In the known devices, the threshed heap is introduced into the H1 non-separator with a high translational velocity randomly, and this creates unfavorable conditions for cleaning the seeds from straw particles and chaff.

In the proposed device, in order to create conditions for better separation of the grain at the exit, the deck is equipped with a 1 m roll installed above the Heii, which is rotated by contact with the deck of the deck.

The drawing schematically shows the proposed threshing device with a separating device, side view (sectional view).

The device contains a receiving tray L vilotpuyu suitable to the roller feeder 2, one of the rollers 3 is spring-loaded, a series of blade beaters 4 located above the movable deck 5, made in the form of an endless conveyor belt tensioned between the rollers 6 and 7. On the output deck fitted over it (above roller 7)

A spring loaded roller 8, rotated by contact with the deck canvas, and between this roller and the final beater 9, there is a reflective shield 10. A non-separator /./, represented by an asniracioppa column, is installed at the output of the decay, and above it is a sloping board 12. For collecting the seeds under the pneumatic separator assembly 13. All components and mechanisms of the device are driven by the electric drive 14 through the transmission system.

Agricultural crops, subject to threshing, are directed along the tray to the roller feeder. The stems, picked up by the movement of the deck, are also under the action of rotating beaters, where threshing occurs (combing, since the tape speed is much better than the speed of the whips). Passing under the rapidly rotating beaters, the stem is pressed against the belt with a roller set at the entrance and retaining the old cKOjjocTb, is fully retracted. The threshed seeds go out under the last beater of the threshing apparatus with a speed

equal to the circumferential speed of rotation of the louiste, hit the Obrezyneppy reflective and current and are guided under the drum set at the exit. The stalk, the exit from the threshing apparatus, along the pitched board is led outside the thresher, a pile coming out of the threshing machine with a small

speed, enters the vertical channel of the pneumatic separator, where it is cleaned by the air flow created by the fan, and the seeds are collected in a container.

Subject invention

Threshing and breeder,

including a roller feeder, a series of paddle beaters positioned on a sliding deck made in the form of an endless conveyor belt and a pneumatic discharge valve installed on the outlet, characterized in that, in order to improve the separation of the grain, the deck on the outlet is equipped with a spring loaded above it roller, driven in rotation from contact with the canvas Dec.
