Description

The invention relates to the field of agricultural engineering, in particular to combine harvesters.

The aim of the invention is to increase the productivity of the combine harvester, reducing the level of grain loss behind it.

The harvester for harvesting crops consists of a stripping device 1, a cutting device 2, a thresher 3. A stripping device 1 includes: a stripping drum 4, consisting of a shell 5 and mounted on it combing combs 6 and disc dividers 7, brush beater -reflector 8, located in front of the stripping drum, auger for collecting stripped heap 9, inclined camera 10.

The thresher 3 consists of a successively arranged receiving brush-vane beater 11 and a curved separating grate 12 installed below it, a rotating pin-brush separator 13 with a mesh separating grating 14, a brush intermediate beater 15 with a separating grating 16 of a threshing drum with elastic brush-type working bodies 17 and the mesh deck 18, the beater-type moulder 19 with the bar-plate deck 20, the cylindrical straw walker of the mesh type 21 with a straw picker particles from its surface 22, as well as the shaking board 23, cleaning 24, the hopper 25.

The technological process of the combine is as follows.

When the combine is moving, the combing device 1 threshes the plants on the vine and delivers the products of threshing of the screws 9 to the conveyor of the inclined chamber 10. The process of threshing the plants on the vine involves aligning and holding inflorescences with disk dividers 7, combing them with combs 6 attached to the drum 4. Threshing products thrown out forward, they reflect and change their trajectory under the influence of the brush beater-reflector 8 and are transported to the screw 9. The inclined chamber conveyor feeds the combed heap to the combine ISU. The brush-blade receiving beater 11 evenly feeds the combed heap into the rotary separator 13, while a part of the free grain is extracted through the curved separating grid 12 to the shaking board 23. The rotary separator 13 releases the bulk of the free grain to the shaking board 23 through the mesh separating grill 14. The remaining heap intermediate brush beater 15 is transported to the threshing drum

17. During transportation, part of the free grain is separated on its separating lattice 16. The threshing drum, acting on the tattered inflorescences with elastic-elastic brushes, softly threshes and separates the main part of the grain located in the tattered inflorescences, which is released through the mesh deck 18. The remaining in the inflorescences is the most hard-to-grind grain is threshed when it enters the beater type 19 and is released through deck 20. Free grain located in the straw is separated on a cylindrical olomotryase 21 mesh type, and of straw particles are removed from its surface and the brush device 22 and reset to roll back grind.

The grain extracted through the separating grids 12, 14, 16, 18, 20, LSG and the straw separator 21, comes from the shaking board 23 for cleaning 24. The cleaned grain is collected in the hopper 25.

The carved stems are cut with a cutting device 2 and stacked in a roll.

Claims (5)

Claim 1. The harvester for harvesting crops on the vine, including a stripping device, a device for separating the grain part from dangling panicles, a grinding machine, a hopper, characterized in that, in order to reduce losses and increase productivity, it is equipped with a threshing and separating device made in in the form of a brush-blade receiving beater, two brush drums with decks and a brush intermediate beater located between them, while pins are installed between the brushes of the first drum, the height of which is less the height of the brushes, and the brushes are installed at an angle to the generators of the drums. 2. The harvester according to claim 1, wherein the device for separating the grain part from the threshed panicles and straw particles is equipped with a mesh cylindrical straw separator installed behind the grinding machine. 3. The harvester according to claim 2, with the fact that the mesh cylindrical straw separator is equipped with a brush cleaning device. 4. The harvester according to π. 1, due to the fact that the brush-paddle receiving beater is equipped with a separating grating. 5. Combine pop. 1, characterized in that the brushes are mounted at an angle to the generatrixes of the surfaces of the drums with alternating right and left tilts.
