Description

2. The thresher according to claim 1, characterized in that, in order to prevent the supply to the collection

of uncleaned grain and cores with wrappers; it is provided with curved reflectors installed in the window.

The invention relates to agricultural machinery and can be used in the construction of threshing machines for corn combine harvesters for selective sowing.

Known threshing corn harvesting combine harvester, containing the threshing apparatus and cleaning with a collection of grain tl.

A threshing machine for a corn-harvesting combine harvester is also known, comprising a threshing apparatus placed in a housing with at least one threshing drum and cleaning having a grain collector with an unloading device. f2j

A disadvantage of the known devices is the slow emptying of their grain collections.

At the moment when the combine finishes harvesting one breeding site, the collection does not completely release the adena from the grain and, due to the fact that mixing the grain from two selection plots is unacceptable, the combine is idle on the night track until the collection of grain is completely empty. Since the selection field contains a large number of cases sown with seeds of various varieties, the time just to combine to empty the collection significantly reduces the productivity of harvesting.

The purpose of the invention is to increase the productivity of the combine by speeding up the process of emptying the grain collector.

The goal is achieved by the fact that a window is made in the case above the threshing drum, and the grain collector is provided with an additional internal wall to form a mesh and the main wall of the collector junction slot communicated with the window by means of an air duct.

In addition, in order to prevent the collection of crude grain and wrapped rods, the thresher is equipped with curved reflectors installed in the window. FIG. 1 is a diagram of a selection corn harvester with the proposed thresher, side view; in fig. 2 - the same view

from above; in fig. 3 - thresher, cross section.

The harvester includes chassis 1, four-slot. Rigid guiding capes 2, pulling rollers 3, tapping the plates 4, feed chains 5. For directing the cobs, there are mounted 6, conveyors 7 and in the upper part of the conveyors - bit feeders 8 with reflective

comb yourself 9.

The cutting device 10 and the screw 11 are designed for cutting and removal of corn stalks. Under the feeders 8 are located the hoppers 12 and the screws 13.

cobs.

Combine thresher contains threshing machine with threshing drum 14 axial type and concave 15, as well as cleaning

with an upper cleaning sieve 16, a lower sieve 17, an extension cord 18 of the lower sieve, a fan 19 and a collection of 20 grains. The latter has an unloading device with connections 21.

The harvester also contains a longitudinal axial partition 22. In the zone of sieves 16 and 17, the partition is made in the form of elastic apron 23. In the upper part of the body 24 of the threshing machine, two process windows 25 are attached. To these are attached the ends of the air ducts 26, the envelopes on the right and

to the left is a housing 24. Inside the collector 20, an additional inner wall 27 is formed, forming with the main outer wall 28 a nozzle slit 29 communicating with the air ducts 26. In the windows 25 there are installed curved plate reflectors 30. The combining with the proposed grind works as follows. When the combine moves, corn stalks, guided by capes 2 and feed chains 5, are picked up by rollers 3 and pulled down by them. When pulling stalks, cobs are drawn off on the stripping plates 4 and fed to the bowl 6 cobs. The partition 22 divides the screw 6 in half, and on one half of the screw has left-side turns, and on the other - right-hand cobs fall into the two right and left inclined conveyors 7. Further processing of the coats is carried out by two non-mixing streams. The harvester can make cleaning both with threshing cobs, and without threshing. In the case of harvesting corn without threshing the cobs, the latter from the inclined conveyors 7 fall onto the reversing beater feeders 8 into the screws of the cobs 13, from where they are unloaded. If the corn is removed from the thresh, then the direction of rotation 7 .4 of the beater feeder 8 is changed. The cobs are fed into the bunkers 12 Further, thrashing, dragged between the drums 14 and the concave 15. Some grain passes through the concave clearances and gets on sieves 16 and 17, and the rest of the flow through the back of the threshing machines goes to the top esheto 16, wherein the grain flows down to the lower sieve 17, and the rods are provided with wraps back and routed in the form of a roll on the ground. From the sieves 16 and 17, the grain enters the collection 20. At the same time, part of the compressed air flow caused by the fan effect of the rotating threshing drums 1 4, through the process windows 25 enters the air ducts 26, from where it enters the collection slot 29 of the collection 20. The compressed air is supplied tengenously to the outer wall 28 and blows the grain towards the nozzles 21, facilitating the quick emptying of the collector 20. The quick release of the collector from the harvested grain allows you to reduce the time just to combine to the night and, consequently, improve the performance of the combine.
