Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to methods and devices for processing grain crops. The invention makes it possible to improve the quality of cleaning, reduce the uneven distribution of the breaks in the width of the cleaning, reduce grain losses and increase productivity. The thresher of a combine harvester contains a threshing and separating device, a device for cleaning the grain and a grain sowing system, in which a threshing device 11 of the axial type, a distribution screw 14 and an exhauster 17 of the non-grain part above the combine cleaning across the entire width of the combine are installed on the common shaft. The casing 15 of the distribution auger 14 is made perforated, and the screw tape auger 14 with variable screw geometry. The pile of heaps is threshed by the device 11, enriched during transportation by the screw 14 along the casing 15, and the non-grain part is brought out of the thresher. 2 sec. Clause and 1 3.

FIELD OF THE INVENTION The invention relates to agricultural machinery, namely, machines for harvesting grain crops.

The aim of the invention is to improve the quality of grain cleaning, reduce the uneven distribution of crushed milk products across the width of the cleaning, reduce grain losses and increase productivity.

FIG. 1 depicts a combine harvester thresher; in fig. 2 - the same, kolosodomolyausha system; in fig. 3 shows section A-A in FIG. 2; in fig. 4 - switchgear auger; in fig. 5 is a view B in FIG. four.

The grain is separated through the holes in the casing 15 by means of a spiral tape 16 with a variable turn geometry and, evenly distributed across the entire width of the cleaning, is fed to sieves 4 and 3, and then

The presence of a colo-squeezer, its systems with working bodies installed successively on the common shaft and located above the cleaning, allows, in the form of a homebolding device 11, to save its load, increase the operating-axis type with corrugated scourges 12 and the axial 13 axial mixing mass, distribution screw 14 with a perforated casing 15 and a screw tape 16 variable geometry of the coil, the excderness of the combine.

The dispensing auger 14 with a variable turn geometry allows simultaneous transportation of the spike grain 17 of the non-grain part with the channel 18 of the rox and efficient separation of the grain to remove the non-grain part of the heap located along the side panel of the thresher, the discharge window of which is located above the cleaning sieves 3 and 4. The dimensions of the cells of the perforated casing 15 can be made of different sizes.

The combine also contains a conveyor 19 chaff and a straw chopper 20. Tape 16 consists of two parts 21 and 22.

Perforated casing 15 distribution screw 14 contributes to the selection of only the grain part with a slight admixture of chaff and uniform distribution across the entire width of the cleaning.

Claims (3)

1. The method of processing the heap, including the isolation and collection of the ear blunt in the threshing-separating mouth. heap after cleaning the grain, domolot, and item 2, where it is threshed. The grain, together with the sex fine-straw particles and non-billowed spikelets, is separated and fed to the device for cleaning the grain, subjected to sequential processing on sieves 3 and 4. The straw is removed to the rear of the combine, and at the same time it enters the grain auger 6 and is transported by the elevator 8 to the grain bin 9. giving a heap of grain for cleaning with its preliminary distribution across the width of the cleaning, characterized in that, in order to improve the quality of cleaning the grain, it is additionally heated, threshed, heaped by the removal of the non-grain part out of the limits of cleaning. 2. M-tiller of a combine harvester, containing a device for cleaning grain and a spike-threshing system, consisting of Unstimulated spikelets along with grain — isolating the elves, brooming devices, with a catcher 5, They are fed into a spike screw, an elevator and a distributor screw 7 and a collar elevator 10, which differs from that. are fed into the housewife, its device is of axial type 11, where they are hammered with corrugated scourges 12, and then, having made a spiral movement around the axis, which can be accompanied by axial mixing guides 13, the pile heap advances into the distribution auger 14 located above the combine cleaning Yushiyu with the continuation of the axial colossome, its devices 11. The grain is separated through the holes in the casing 15 by means of a spiral tape 16 with a variable turn geometry and, evenly distributed across the entire width of the cleaning, is fed to sieves 4 and 3, and then 0  in the bunker 9 grains. The non-kernel part of the ear heap is advanced by the distribution screw 14 into the exhauster 17 of the non-cereal part, being a continuation of it, which in turn directs the heap along channel 18 to by, and freed from the grain in the distribution auger 14, takeaway M tiiri I, jLLinvrvt Immediately beyond cleaning. The presence of a grinder, her system with working bodies installed consistently on the common shaft and located above the cleaning, allows to reduce its workload, to increase the productivity of the combine. The implementation of the distribution auger 14 with a variable geometry of the coil allows you to simultaneously transport the pile of heaps and effectively separate the grain, Roch and effectively. Separate the grain, Perforated casing 15 distribution screw 14 contributes to the selection of only the grain part with a slight admixture of chaff and uniform distribution across the entire width of the cleaning. Invention Formula 1. The method of processing the heap, including the isolation and collection of the ear heap after cleaning grain, domolot and giving a heap of grain for cleaning with its preliminary distribution across the width of the cleaning, characterized in that, in order to improve the quality of cleaning the grain, it is additionally heated, threshed, heaped by the removal of the non-grain part out of the limits of cleaning. 3. The thresher of a combine harvester according to claim 2, characterized in that the screw is made with a variable turn geometry, wherein the forming screw surface device is made in the form of an auger with a perforated casing at the inside diameter of the turn and equipped with a screw axis of the screw, and on the outer one with a transporting device for inclining it in the direction opposite to the non-grain part of the grain. in order to reduce the uneven distribution of the domolot products across the width of the cleaning, reduce grain losses and increase productivity, the distributor. 8 2 And 10 20 nineteen 17 Bb Phage.
