SU1210721A1 - Two-flow separator of grain combine harvester - Google Patents

Description

one

FIELD OF THE INVENTION The invention relates to agricultural machinery industry and can be used in coarse heap separator designs for combine harvesters.

The purpose of the invention is throughput capacity.

Fig. I schematically depicts a combine harvester with a double-flow separator; figure 2 - node 1 in figure 1; on fig.Z - node P on fig

The combine harvester consists of a threshing-separating device 1, a runner-mounted main 2 and auxiliary 3 straw walkers, a divider 4 coarse heap and an threshing device with a threshing drum 5, a feed 6 and a fender beater 7 located between the divider 4 and the auxiliary straw walker catfish-3. On the section with key 8 of the main straw walker 2 located under divider 4, the comb 9 is secured, and the fingers 10 of the divider 4 are placed between these dies at the top position by key 8 (FIG. 2). The latter are made with cantilever sections 11, blocking the gap A between the keys 8 and concave 6 (fig. 3).

Combine with the proposed separator works as follows.

107212

When the combine moves in the field, the grain mass enters the threshing-separating device 1, from where a coarse heap is thrown on

The main straw walker with 2, and a layer of a certain thickness goes to the divider 4, while this free grain is made from a coarse heap. The fingers 10 of the divider 4 capture the coarse

10 heaps and direct it to the threshing drum 5 with concave 6 for repeated threshing, with the fingers 10 of the divider 4 at the upper position — the button 8 goes between the comb 15 9 attached to the section under the divider 4 (FIG. 2). The threshing bug Raban 5 with a concave 6 makes a coarse pile, and the beater 7 throws it onto the auxiliary straw walker from 3. Clearance A (FIG. 3) between concave 6 and the keys 8 of the main straw walker 2 overlaps with cantilever sections 11 of combs 9, which excludes

25 spilling of stems from the sexual or panicles and ensures the complete flow of the coarse heap into the threshing drum 5. Selected grain from the auxiliary straw walker 3

30 is dumped onto the main straw walker with 2 and then fed to the cleaning and into the hopper, and the straw is dumped into a swath or collected in a hopper.

Claims (2)

1. A TWO-THREAD GRAIN CLEANER SEPARATOR containing keys with combs, a main straw walker, an auxiliary straw walker mounted above it, a rotating finger divider to feed part of the rough heap from the front of the main straw walker to the auxiliary, as well as a beating machine with a drum, a drum and a drum located between the divider and the auxiliary straw walker, which means that, in order to increase throughput, the key comb of the main straw walker is located nye before the finish threshing device, made with cantilevered portions for closing the gap between the keys and concave. _β <e 2. Two-line separator in π. 1, characterized in that the fingers of the divider are placed between the combs of the keys of the main straw walker at the upper position of the latter. 12X0121 'ns Put. 1
