Description

(54) MOLOTILNO-SEPARIAN DEVICE

I

The invention relates to the Agricultural Machinery Industry, mainly to the threshing-separating equipment (installed on threshers and combine harvesters.

Known threshing and separating device, containing a drum with a casing, the axis of which is located in the direction of mass supply, lattice deck clasps the drum from the bottom, and also directs the hchchi elements in the form of plates placed on the drum casing.

However, in this device, when threshing, the whole mass, except for fine impurities and grains that had woken up through the deck, moves along the drum, therefore, for complete cracking of the grain from the straw, it is necessary to increase the mass passing time in the threshing chamber, this is increased. the angle between the directions of the plate and the axis of the drum or an increase in the length of the threshing chamber, which leads to additional destruction of the stems and contamination of the grain pile.

The purpose of the invention is to improve the separation process.

This is achieved by the fact that the mass grub elements are made in willow.

rods, cantilever mounted on the skin with the formation of a lattice, (placed between the drums and the upper part: casing

FIG. 1 shows a schematic side view of the device; in fig. 2 the same, top view.

The device consists of a casing 1, a conveyor belt 2, a threshing drum 3, a trellised deck 4, guide elements 5, an upper casing 6, a FAN 7, a conveyor of Pile 8.

The elements 5 are made of arcuate rods, which form a lattice between the drum 3 and the casing 6.

The rods are fixed on the upper casing 6 console and rotated in the direction of the straw.

Works threshing and separating devices in the following way.

The product to be threshed is transported by conveyor 2 to the threshing apparatus, where it is picked up by drum 3, dragged through the slatted bed and fed to the zone of elements 5. The process is repeated several times until complete threshing and separation of the grain from the straw.

When the mass moves through the lattice deck 4, threshing occurs. Minor impurities and grains are requested on the conveyor 8 of the pile. When the mass moves in the area of the guiding elements 5, the straw is pressed against the rods and moves along the axis of the drum along a screw line and to the fan 7, which carries it out of the threshing chamber, and the grain, which did not have time to spill through deck 4, passes between the grid formed rods of guide elements, slides along the concave surface of the casing 6, and. enters the lattice deck again.

To adjust the device's throughput, the rods can be swivel.

The formula of the invention: A threshing-separating device containing a drum with a casing, whose axis is located in the direction of mass supply, the trellised deck, the drum encircling the bottom, as well as control elements, characterized in that, in order to improve the separation process, the directional elements are made the form of rods, cantilever-mounted on the casing, with the formation of a lattice. placed between the drum and the upper part of the casing.
