Abstract

The invention relates to corn harvesting machines and serves the purpose of reducing the energy costs of feeding the mass to the straw walker. The unit contains a combine harvester, in the case of which there is a hammer-separating device, including a deck, a straw walker from 19, a chopper 3 mounted on the combine in front of the corn harvester. The prefix has an inclined chamber 2, a stalk auger with a blade beater, and an auger cob with right and left windings and left and right parts of the beater. To reduce energy costs for the supply of leafy mass from the straw walkers and the inclined chamber 2 in width, they are made in three sections: the stem auger has right and left windings separated by a paddle beater located opposite the middle section of the inclined chamber. When the machine moves along the rows, the cobs are separated from the stems and fall onto the auger augers, with which they are fed into the threshing and separating device. In the two side sections of the deck, the cob is threshed and the grain is fed into the hopper. The stalks after cutting off the cobs are cut off and the stem auger is reduced into one stream and the beater is fed into the inclined chamber 2, from where the beaters are moved to the threshing apparatus and fed to the straw walker from the middle section of the deck 19. enters the shredder 3 and is piped to the vehicle. 7 Il, SL С V4 N О С С) О Fig1

Description

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, corn harvesting machines.

A combine harvester with a corn harvesting attachment is known, which contains an inclined chamber with paddle beaters, the latter of which is provided with beams located between the blades, the bottom of the inclined chamber is provided with a protrusion along the last beater, and a threshing device.

The disadvantage is a significant loss of grain in the leaf-stalk mass due to the fact that low-lying cobs, as well as cobs from lodged plants and the grain expelled from the cobs when they are cut from the stems, fall into the leaf-stalk mass.

A tilted chamber of a corn harvester is known, comprising sidewalls, a bottom with orienting elements and tines consistently located above them.

The disadvantage is that the separation capacity is not satisfactory due to the fact that the process of feeding cobs for threshing is carried out jointly with the stalks. This leads to a significant loss of grain to the leafy mass and requires a large amount of energy for the threshing process of the cobs. In addition, the grain is moistened from. juice stems, which requires additional costs for drying.

Known machine for harvesting maize, comprising a combine harvester with a separation-MO lotilno device deck, solomotr catfish, chopper, corn pad, comprising snapping, cutting unit, feeder, screw stems with beater blade and auger cobs right and left winding and beater. The shredder has a silo line installed above the combine, the discharge port of which is located above the initial section of the straw walker.

When the unit moves along the row, the stems fall into the working channels of the attachment, where the garlics are separated from the stems and fed to the thresh, and the stems are cut by the cutting apparatus and the stem auger are sent to the chopper. The crushed mass is fed through the silage duct to the initial section of the straw walker, during its passage the grain is separated from it. The recovered grain enters the combine bunker, and the leafed mass is fed to the vehicle via the silo line. The disadvantage is the high energy intensity of the feed mass to the straw walker.

The aim of the invention is to reduce the energy costs of feeding the leafy mass to the straw walker.

The goal is achieved by the fact that

The deck of the threshing and separating device and the inclined chamber are made in three sections in width, with the middle section of the deck having the shape of a smooth chute expanding as the material moves.

The maize unit contains a combine harvester, in front of which a corn-harvesting attachment device 1 is installed, connected to an inclined combine

, camera 2, and hung behind the combine

chopper 3. The prefix includes a screw

cobs from the left 4 and right 5 windings,

the left 6 and right 7 parts of the beater, divided by screws with the left 8 and the right 9 windings. Below the ears of augers there is a stalk auger, which includes the left 10 and right 11 windings, separated by a paddle beater 12. The ears auger has a weekend

0 windows 13 and 14, and the auger of the stalks - the output window 15. The combine contains a thresher with a threshing-and-separating device, including a deck made of three sections 16, 17 and 18, located against

5 sections of an inclined chamber, and the middle 17 section of the deck has the shape of a smooth grooved bottom. The straw walker is located at the rear of the combine's threshing and separating device from 19. Output windows 13 and 14 are filled on the casing 20 of the auger cobs. The left 6 and the right 7 parts of the cob auger bit are located against the extreme 21 and 22 sections of the inclined chamber, in which the tines 23 and 24 are located. Extreme sections

5, 21 and 22 are separated from the middle section 25, in which the beater 26 is located, by partitions 27 and 28. The middle section 17 of the deck has side walls 29 protruding above the working surface 30 of the side sections 16 and 18.

0 Maize unit operates as follows.

When the machine moves along the rows by the working body of the prefix, the cobs are separated from the stems and fall onto the auger of the cobs. The collected cobs of the left 4 and right E coils of the screw and the left 6 and right 7 parts of the beater are fed to the threshing and separating device of the combine in the extreme sections 21 and 22 of the inclined chamber. In the side sections 16 and 18 of the cob deck

are threshed and the grain after cleaning enters the combine bunker.

To prevent the cob and the threshed grain from the side sections-16 and 18 of the deck into the middle section 17, the side walls 29 of the middle section 17 protrude above the working surface 30 of the side sections 16 and 18 of the deck in the front part more than in the back, which determines a larger the gap at the entrance of the mass in the threshing machine than at the exit from it. Since the passage for the stems is made widened, the protruding side walls of the middle section are arranged at a certain angle to the threshing ears. However, they do not prevent the mass from escaping from the deck sections, since the angle of inclination of the walls of the chute is very small (7 °) and much smaller than the angle of friction of the mass on the metal surface (30-40 °). The stalks after cutting off the cobs are cut off by a rotary cutting device of the attachment, the coils 10 and 11 of the screw of the stems are reduced into one stream and the beater 12 is fed into the inclined chamber 2. The inclinations of the inclined chamber move the stems into the threshing machine, where they are picked up by the drum and along the middle section 17 of the deck are fed to the straw walker from 19. At the same time, grain coming out of the cleaning of the combine is released from the pile.

The weight, coming down from the keys of the straw walker 19 and the cleaning of the combine, enters the chopper 3 and is fed through a pipeline into the vehicle.

The unit collects all biological

maize harvest, including impurities after threshing, in one pass of the aggregate, is formed from impurities and leafy mass one stream, crushes it and

The silo pipe feeds into the vehicle.
