Description

The invention relates to agricultural machinery, in particular to machines for harvesting crops.

A known combine for harvesting crops, including a header and an inclined chamber attached to the frame, a transverse threshing apparatus and a transverse screw straw separator having a partially trellised deck and a casing with unloading windows [1]. ''

A disadvantage of the known combine is that it is impossible to increase productivity on it, since an increase in the separation capacity leads to a significant increase in the transverse dimensions of the machine.

The purpose of the invention is to increase the performance of the harvester.

This goal is achieved in that the combine is equipped with at least one additional screw straw separator with input and output windows, the additional screw straw separator located along the longitudinal axis of the combine, and its input window located under the output window of the transverse screw straw separator, additional screw straw separators are made rotary10 mi in the vertical plane, and the deck of the transverse straw separator is made sectional with the possibility of rotation of the sections relative to each other, cr In addition, on the auger of the additional straw separator, corrugated whips are installed to crush the erosol.

The harvester for harvesting grain and other crops consists of a header 1, an inclined chamber 2, attached to the frame of the thresher 3 with side panels

4, on which a transverse threshing apparatus 5 is installed, a screw · straw separator 6 is located parallel to it, containing a rotor (screw) 7, covered by a deck 8, partially made in the form of a grill and having unloading windows 9, impellers 10 are installed in the window area on the rotor, the rotor is installed in the casing 11 with a conveying device 12 for transferring the grain heap to · cleaning 13.

One or more additional screw straw separators 14 are installed so that their screws 15 are crossed with the screw 7 of the transverse straw separator b, and their input windows are located under the output windows of the transverse straw separator. The screws 15 are covered by decks 16 having input 17 windows and output 18. Decks 16, in turn, are covered by a casing 19 with a transporting device 12. In the casing 19 against the inlet and outlet windows'17 and 18 are made necks 20 and 21. Additional auger Straw separators 14 are mounted rotatable in a vertical plane relative to the transverse straw separator b and are connected to the hydraulic cylinder 22. The deck 8 and the casing 11 of the straw separator 6 are made sectional with the possibility of turning the movable sections 23 relative to the fixed sections 24. optional straw separator 25 and straw separator 6 are connected rotary, for example, using a thrust bearing 26.

The rotors of the straw separators are made in the form of screws with a winding 27, and on the screws of the additional straw separators a dominating device can be installed, for example, in the form of corrugated whips 28 installed on the turns of the screw. Pests are installed on all turns of the screw, on part of the turns or periodically. At the exit of the straw from the straw separators 14, the impellers 29 are installed on the rotors. The combine is equipped with 30 grain and 31 spike elevators.

The harvester works as follows.

The bread mass cut by the header 1 is fed by an inclined chamber 2 to the threshing apparatus 5. In the threshing apparatus, the bread mass is threshed. Part of the grain (80-85%) · together with the sexual and finely straw particles passes through the holes of b deck 8 and enters the wind-screen cleaning

13. The straw with the remaining grain and unfrozen spikelets enters the transverse straw separator 6, where the screw 7 moves to one side if the additional separators 14 are located on one side of the thresher 5, or divide the straw flow into two and drive each part to left-handed and left-handed additional straw separators 14. During the movement of straw along the transverse 6 and longitudinal straw separators 14, grain residues are released and transporting device 12 is fed to the beginning of the shaking board wind sieve cleaning 13. Straw is ejected through the exit windows 18 of additional straw separators 14 to the middle or outside the combine. The grain cleaned at the cleaning 13, enters the grain elevator 30 and is transported to the hopper. Spikelets allocated by the extension of the screen, the spike elevator 31, transmit the grinding to the threshing apparatus 5.

The use of one or more additional screw straw separators allows you to increase the productivity of the combine and, in addition, depending on the working conditions, the intensity of grain separation from the straw is controlled by rotating the additional straw separators in a vertical plane relative to the transverse straw separator.
