Description

Known grain pickers include a header, two hammer mills, a cleaning, and two bunkers. The grain threshed by the first threshing device, as more biologically less, is sent as a separate note for cleaning, and then is collected in a separate bunker. With ethanol, to prevent the mixing of grains from separate streams, separation filters are installed on the cleaning sieve or are cleaned on two independent devices. In either case, the purification and removal of the whole grain, threshed with Obam threshing devices.

In the proposed combine, in order to improve the working conditions of the cleaning and increase the productivity, under the first threshing device there is a receiving chamber and a transporting device for feeding grain from this chamber to the hopper, mine cleaning. In this case, the first Agolote device is located on the header directly behind the cutting device, and the transport devices include a belt conveyor, whose width is equal to the width of the threshing device, and a system of screws.

device. The latter contains a pin or bil drum 3 with a bumper and iodobarabanye 4. Narrowing mass is installed behind the threshing drum

augers 5 and floating: 1st conveyor 6 inclined camera. Below the drum drum is a reception chamber 7 with a transnorter 8 for feeding a pile of grain to the constricting screws 9. The inclined chamber has a lattice

bottom 10. Augers 9 grain mass is fed to the Elevator 11, which directs it into the hopper 12. At the entrance of the threshing device 13, a receiving beater 14 is installed, and an exit beater 15 is installed at the exit. Next, the straw walker 16 and cleaning 17 are installed in the hammer case, including screen 18, top 19 and bottom 20 louvered sieves. A grain auger 21 with an elevator 22 and a head auger 23 with an elevator 24 ending with an upper auger 25 are mounted in the bottom part. The sieve mill of the combine is blown with a fan 26. A well-known device can be used for collecting straw, such as a stacker 27 with a straw picker 28

and polisher 29. The top sieve has an extension 30. For the laid bread, the cutting apparatus is equipped with lifters 31.

discharge screw 34. The hopper 35 for collecting grain from the second threshing device also has upper 36 and ni / Kiiiui 37 screws.

The combine works in the following way. When harvesting plant stalks with sticks of reel 1, they are fed to cutting unit 2, and then the cut mass is fed to the first threshing device, where it is threshed with a bilder or pin drum 3 and separated into a mass 7 through a lattice concave 4. The mass of the screws 5 is narrowed down and then conveyor 6 is fed to the receiving bit M. When mass moves to the receiving beater, additional grain is released from the pile through the grating bottom; e of the screws and grating days w (e 10 of the inclined chamber; in this case, the mass is poured into the receiving chamber 7.

The receiving beater 14 delivers the mass to the second threshing device 13. A part of the threshed grain passes through the trellis concave and goes to the cleaning, a part along with the straw is guided by the breaker beater 15 wa straw walkers with 16; at the same time, a part of the grain is extracted through the comb and enters the page board of the screen 18. The grain selected for the straw walker and the small pile go to the screen of the screen.

Grain that has passed through the screen of the screen is poured onto the upper louvered sieve 19. The sieved grain and part of the small pile are fed to the lower sieve 20. Both sieves are blown with a fan 26. Pass through the sieve holes 20, the grain enters the grain auger 21 and the elevator 22 is fed to a hopper 35 in which the grain is evenly distributed by the screw 36.

The pee gilded heads, passing through the holes of the upper sieve extension, with a spike screw 23 and an elevator 24 are fed to the upper spike of the screw 25, which is turned into a domol. The straw from the straw walker by the straw crusher 28 and the chaff with light impurities from the cleaning polisher 29 is fed to the stapler 27. Upon filling, the stacker is discharged.

In the event that the hopper 35 is fully filled with grain, it is unloaded into vehicles by the unloading screw 37.

Grain and a small pile, separated into chamber 7, are conveyed by conveyor 8 to narrowing augers 9, and then to elevator 11, feeding, the mass to bunker 12. In the bunker, screw 32 distributes grain pile and

auger 34 - unloading.

In separate harvesting, the reel 1 is removed, and a pick-up is installed instead of the cutting unit. When selecting the weight of the roll pick,

picking up the mass, feeding it to the first threshing device, then the process repeats.

With such a combine scheme, which ensures the selection of biologically valuable grains with a crush (sex), the load on cleaning the combine, which limits its productivity, is significantly reduced. All other things being equal, this gives an increase in combine productivity.
