Description

The currently used combine harvesters for harvesting cereal crops, differing in high productivity, however, give considerable losses from grain lacking from straw, reaching up to 5% and more.

To reduce losses, one must either cut the bread very high, leave a significant part of the straw on the field, or work on the incomplete capture of the header, which reduces the productivity of the combine.

Another bottleneck of the harvester is the lack of a sex separator.

Straw, along with genital small heaps, is scattered across the field, which makes it impossible to quickly release the field to produce peeling. In addition, most of the chaff is lost, and the field is littered with weed seeds.

The harvester of the proposed device, in contrast, quite well ensures the shaking of grain from straw, which falls into the suspended straw gathering, located on the side of the combine. At the same time, the chaff, which does not spread across the field and does not litter, is separated from the straw.

it is supplied by weeds, and rum is transported by transport to a peeler, or the like.

All this is achieved, according to the invention, by the fact that the straw after the straw walker is diverted to the side of the combine. This is done with the aid of a plate conveyor located at an angle of 90 ° to the straw and the shaft placed above it with fingers arranged along a helix.

In FIG. 1 shows a longitudinal section of a combine; FIG. 2 shows a rear view of the same combine with an eolomotdel section along the shaft axis with fingers.

As can be seen from the drawing, the conveyor / pile is made somewhat longer than that of the used combines.

In front of the discharge upper end of the conveyor 1, a grate 2 is installed, above which an additional beater 5 is placed. After it, a straw separator is installed.

The latter comprises a beater in the form of a rotating shaft 4 with fingers arranged along a helix, a casing 5, the back wall of which is made of a lattice, and transverse

a plate conveyor 6 through which the grain and small impurities that are ejected from the straw fall down onto the bale.

In comparison with a conventional construction, the first 7 is raised slightly higher, which makes it possible to place a second one under it.

For raising the chaff, a conveyor 14 is installed in the overhead sealer or trailer trolley.

The workflow proceeds as follows.

The threshed bread rises on the pile conveyor 1 and rises it up.

When the heap conveyor reaches the end, the grain and small impurities that have passed through the grate 2 fall into the first cleaning 7. The straw is picked up by the beater 3 and transferred to the straw separator 4-6, where the shaft 4 catches the straw and grind it all the way it advances it to the right into the straw gatherer 15, from which, when a certain weight is reached, the stacks are automatically thrown to the ground.

Grain and small impurities that have fallen through the plate conveyor 6 fall onto the first bilge 7.

In the first bilge 7, large impurities are separated from the grain, and in the second 8 - small impurities.

The unmilted spike enters the ear auger 13 and is sent back to the threshing drum.

The grain cleaned on the second bale 8 by the elevator 11 is fed into the bunker 12. From the bunker the grain with the open valve 16 is poured by gravity into a car or into a cart.

Unloading can be done on the go and does not require any additional devices.

Thus, on the right side of the combine's thresher, haystacks fall, on the left side, grain is unloaded from the bunker by gravity into the car, and the rear of the half-transporter is fed to the receiving trolley and, not falling to the ground, transported to the farm.

The subject matter of the invention.

A harvester with a straw walker, made in the form of a conveyor with beaters located above it, characterized in that in order to divert the straw to the side, a cross conveyor 6 is placed behind the straw walker, above which is mounted a shaft 4 with fingers arranged along a helix.
