SU86308A1 - Adaptation to the second cleaning of the combine Stalinets-6 - Google Patents

Description

Existing grain cleaning devices in combines do not provide a sufficiently pure product, since the second cleaning does not provide complete separation of large and light impurities, and allows for the possibility of grain gathering on the straw walker.

In order to capture the large and light impurities released by the second cleaning, an additional skid board, a screw with a casing and an elevator are installed on it, and an empty-plate with an adjustable plate is inserted into the mass distributor along the cleaning slots.

FIG. 1 shows a diagram of the second cleaning of the combine; in fig. .2- view of page board with plates.

Grain from the elevator 1 of the first cleaning enters the upper sieve 2 of the second cleaning.

On the upper sieve 2 of the louvre type, an air stream separates the remaining lightweight litter (wallpaper, chaff) from the product. The efficiency of separating light impurities depends on the operation of the fan, therefore, the lower breakdown sieve 5 is mounted in the mill in such a way that it interferes with the air flow as little as possible. Large heavy impurities are released on the lower sieve pan.

To distribute the mass across the widths of the second cleaning sieves, there are installed screws 6 with blades welded along its entire length between the spirals, a casing with an oblique cut, a guide visor 7 and a slope of the skid board 6 when rotated. In the opening, there is a gap on the pitch of the pitched plank 8. The latter has, over the entire length, hinged plates 9 placed on an edge, which by means of connecting rod 10 can be installed (along the plane of the board) at different angles, ensuring uniform Achu product width sieves.

Thus, a sleeping board strut completes the operation of the distribution auger.

In addition, in the second cleaning, there is a rear tread plate 3 and a screw 4 with a casing designed to catch and reject as part No. 86308

threshing works, which are then fed by an elevator 11 to the mesh to the holder 74 and into the bags.

An additional cylindrical cleaning 15 is installed above the combine bunker for separation of a mass of small heavy impurities from the second cleaning coming through the sleeve 12. The cleaning consists of a blade auger 17, a seeder sieve 16 with a diameter of about 400 mm and a length. 1.000 mm, screw 18, retraction of seeding, and chute 13, along which fine impurities (sub-seed) are also sent to bag holder 14 and then collected in bags together with the litter separated by the second cleaning.

When cleaning the blade auger 17 transports the product and scatters it over the surface of the sieve. The sieve has the opposite screw angle; This ensures an increase in the sieve useful area and an intensive separation process even with a low friable mass.

Subject invention

The adaptation to the second cleaning of the combine with the use of additional cylindrical cleaning and elongated sieves, characterized in that, in order to catch large and light impurities emitted by the second cleaning, an additional ramp, screw with casing and elevator are installed, and the mass distributor on the cleaning sieves An adjustable plate is inserted into a sleeping pad.
