Abstract

The invention relates to S.-x. mechanical engineering, in particular to the grain cleaning and air-screening machines. The purpose of the invention is to improve the quality of cleaning and reduce grain losses by optimizing the aerodynamic regime. The separator includes a hopper 1 with a turner 2 and a flap 3, consisting of closed tapes 4 and 5 feeding device, jigging chamber (K) 8, receiving K 9 enriched heap, air channel 6 with louvered bottom 10, pressure fan (B) 7 and K 16 sieve cleaning. At the same time, B 11 is installed in K 16, the upper sieve (P) 12 and the lower R 13, screws 14 and 15. From the bottom 10 K 16 is separated by a board 17 installed under, bottom 10 with a slope towards K 8. The bottom end of the board 17 is connected to K 8 via a window 18. Accelerated by ribbons 4 and 5, a grain heap is thrown into the air flow created in channel 6 V 7. Grain passes through K 9 to P 12 and then to P 13. Under the influence of the oscillatory movement P 12 and 13 and the air flow generated by B 11, the cleaned grain enters the auger 14, the unwaxed spikelets go to the auger 15.

The invention relates to agricultural machinery, namely, to grain cleaning and air-screening machines, and is an improvement of the separator according to the author. St. No. 1158252.

The purpose of the invention is to improve the quality of cleaning and reduce grain losses by optimizing the aerodynamic regime.

impeding the normal operation of the separator. When a heap of accumulation is accumulated sufficiently thick, blinds are opened, due to which portions of impurities fall onto cattle board 17, where, under the influence of their own gravity, through window 18 enters the sediment chamber 8. Since the rear zone of the air channel is isolated from the chamber by a cleaning grid, opening the blinds does not affect the work

The drawing shows a separator, a general sieve cleaning, view. In a known separator under the action

The separator contains a hopper 1 with a thistle-air flow in a horizontal air channel; the impurities are compacted and fall onto the sieve portions of about 2 kg, with a pritel 2 and a damper 3, feeding the device, -the neck of two closed tapes 4 and 5, pulled on the drum .

than this chunk has high connectivity.

Under the feeding device is located. When such a portion hits the sieve, the horizontal air channel 6 is connected; the work of the latter, which is connected to the discharge fan 7 and the sediment chamber 8, deteriorates significantly. At the bottom

air channel 6 installed receiving

since a portion of the impurities passes over the surface of the sieves, almost without breaking its connection, therefore, a part of the grain, the chamber 9 of the heated pile and comprehending it in the impurities, does not stand out on the bottom of the screen 10. Sieve cleaning It enters the waste, which causes the fan to turn on the fan 11, the top 12 and lead to an increase in grain losses. In the pre-bottom 13 sieves, as well as screws 14 and 15. Lagged separator when opening the blinds Sieve cleaning is installed in chamber 16 under the action of a sieve cleaning accumulated on them, which are separated from the bottom of the impurities and fall down on that air channel 10 with a sloping board 17 , 25 tilting board, which comes in osa-installed at an angle of 29-40 °. The lower daughter chamber, without disturbing the mode of operation, the end of the ramp board 17 is connected to the sediment chamber 8 through a window 18. The separator is mounted on the frame 19.

The grain heap separator works as follows.

The original grain heap with the help of the agitator 2 is fed to the bunker 1 in the feed30

When the shutters are opened in a known separator, the air flow from the horizontal air channel rushes to the surface of the sieves, disrupting their operation, which adversely affects the quality of the separation. In the proposed separator, isolating the air channel from the sieve cleaning chamber allows to increase

When such a portion hits the sieve, the work of the latter Since a portion of impurities passes along the surface of the sieves, almost without breaking its connection, therefore, a part of the grain containing impurities is not released on the sieves and enters the waste, which leads to an increase in grain losses. In the proposed separator, when opening the blinds under the action of a portion of impurities accumulated on them, the latter fall onto the cattle board, from which they enter the sediment chamber, without disturbing the operation mode sieves When the shutters are opened in a known separator, the air flow from the horizontal air channel rushes to the surface of the sieves, disrupting their operation, which adversely affects the quality of the separation. In the proposed separator, isolating the air channel from the sieve cleaning chamber allows to increase purity of grain and reduce its losses Application of the proposed separator compared with the known 20% loss of grain caused by the precipitation of grain on portions of impurities on the surface of sieves, and also the number of grain is up to 98.5%. ,,, „,.„ „„,. „„ ..  No. 1158252, characterized in that.
