Description

Aq-sial threshing machines are known, consisting of a cylindrical vertically disposed casing with a drum rotating inside carrying a row of protrusions in a spiral. The strawomist part of the grain mass moves along an annular chamber, and the outer casing is a deck in the form of louvre-like plates.

A distinctive feature of the proposed axial thresher is that the wrap-up, cone-shaped cone (rotor) is made reschetch and faceted, which increases the degree of threshing and improves the conditions for the separation of grain from straw.

The drawing shows the technological scheme of the axial

HAMMERS.

The axial thresher is intended for installation on a grain harvester or a stationary thresher. It consists of a conveyor belt /, a receiver 2, a rotating rotor 3, made in the form of a lattice faceted cone, a stationary ring casing 4 with a grooved surface, a separation grid, fans and motive mechanisms.

The grain mass entered in the receiver 2 is captured by the conical part of the rotor and distributed around the entire working area. At THIS, the grain is partially wiped and separated, which, together with light impurities, is sucked in by the fan through the rotor grid 5 downwards, falls into the second grid 6 and further Mix the discharge screw into the hopper.

The non-threshed heads that hit the grill 6 are ground and the blades 7 move to the periphery and are sucked in with the straw into the annular chamber.

On the output part of the rotating rotor, ring-shaped bats 8 are installed, and on the fixed shell-and-ring brushes 9, between which a controlla adjustable slit is formed, from which the remaining grain is extracted.

When the straw moves in the annular chamber in a spiral upward, the grain is released from it and is withdrawn by the auger into the bunker.

Subject invention

An axial thresher with the use of a vertical rotor and the immobile surrounding it is an annular shape, which serves to remove the straw-like part of the grain mass, characterized in that, in order to better separate the grain from the straw and increase the degree of thresh, the mouth "p made in the form of a lattice faceted cone., the holes in which are designed for the passage of grain and ears.
