Description

The utility model relates to grain-and seed-cleaning equipment designed for use: in agricultural enterprises, in the milling-grain elevator and animal feed industries for cleaning seeds from impurities that differ from the main seeds in aerodynamic properties and size.

An air-sieve machine is known, containing a frame, a pneumatic system for separating impurities with an air stream that differ from full seeds in aerodynamic properties, and two sieve mills for separating small and large impurities from a pile of seeds. The pneumatic system includes a diametral fan, a power supply device, a channel to sieve aspiration, a channel after sieve separation, coming down from the upper tier of sieves of the second mill of the seed fraction, a channel after sieve separation coming down to the same channel after sieve separation from the lower tier of the sieves of the second mill of the seed fraction material, mechanisms for adjusting the air flow rate in the pneumo-separating channels after the sieve separation, dust precipitation chambers with impurity-removing devices (patent specification RU 223 154 C2, IPC В07В 4/00, published: Bull. No. 4, 2004).

The lack of machines - low efficiency of the separation process of the components of the heap of seeds of various agricultural crops using the air flow in the channel after the sieve separation due to the passage of seed into the second channel after sieve aspiration through the first channel after sieve aspiration and, as a result, increased specific loads of seed flow material per unit length of the cross section of this channel.

Known air-sieve grain cleaning machine, including a pneumatic separating system installed on the frame with pre-sieve and post-sieve suction channels, feeding devices, dust-collecting chambers with output devices, a dust collector, adjusting flaps and a sieve part consisting of the upper one-tier sieves and the bottom two-tier sieves sieve mills. At the end of the upper tier of the sieves of the lower sieve mill, a discharge chute with a rotary valve is mounted; a rotary tilting board is installed under the third sieve of the upper sieve camp; a frame is installed in front of the upper tier of the sieves of the lower sieve camp, which can be opened or closed with a blind shield. In the wall of the channel of post-sieve aspiration, facing the sieve mills, one above the other, the upper and lower devices for introducing grain into the channel (prototype, patent specification RU 2393030 C1, IPC W07B 4/02 (2006.01), A01F 12/44 (2006.01), published: 06/27/2010, bulletin number 18). A disadvantage of the known machine is the low efficiency of the process of separating the components of a pile of seeds of various agricultural crops entering the pneumatic separating channel after the sieve material separation from two tiers of sieves simultaneously, due to the increased specific load of the seed flow per unit cross-section length of this channel.

The task of the utility model is to improve the quality of cleaning a heap of seeds from impurities that differ from full-fledged seeds in terms of aerodynamic properties entering the pneumo-separating channels of the seed flow.

EFFECT: reduced loads per unit length of pneumo-separating channels.

The technical result is achieved by an air-sieve cleaning machine for a heap of seeds, including a pneumatic separating system installed on the frame with pre-sieve and sieve aspiration channels and a sieve part consisting of upper and lower sieves, contains two sieve-aspiration channels from which the first sieve aspiration channel is made with the possibility of withdrawal of seed material on the side of the machine and the entrance to it is located in the area of the gathering from the unloading device of seed material, cleaned in the upper tier of sieves, and watts swarm poslereshetnoy aspiration channel configured to output the seed of the car and down entrance is arranged in a region with a descent of the unloading device seed purified on a lower tier of sieves, wherein

The air-air cleaning machine heap works as follows.

A heap of seeds through the loading neck 17 of the receiving chamber 16 via the feed roller 18 enters and is evenly distributed over the entire width of the outer surface of the cylindrical sieve of the scalper 19. The seeds, large short, light and small impurities pass through the openings of the cylindrical sieve and are sent to the first pneumoeparating channel 22, where dust and partially light impurities are emitted from a pile of seeds. Then the seed flow enters the divider 3 seed flow, where it is divided into two equal streams, which are sent to the upper tiers 4 and 11, respectively, of the upper 2 and lower 10 sieve mills, and large long impurities (straw, spikelets, etc.) are removed by gathering On the transportation sieve 5 of the upper sieve mill 2. After separation on the transportation sieve 5 of the upper sieve mill 2, large long impurities are sent off from sieve 4 through the flow of straw impurities 20 into the waste bin of the processing line, and the material passed through the sieve 5 sent to the divider 3 seed flow, where it is divided into two equal flow, which are sent to the upper tiers 4 and 1, respectively, the upper 2 and lower 10 sieve mills. From the incoming flow of seed material, dust and partially light impurities are separated into the first pneumo-separating channel using an air flow, which, together with the air flow, are sent to the aspiration system 21 of the machine, where they are released from the air flow into the sediment chamber 23 and removed from the machine by bunker waste processing line. On the upper tiers of sieves 4 and 11, large impurities are released from the seed streams, which are sent to the waste bin along the corresponding unloading devices 6 and 12 of large impurities, and the seed streams cleared of large impurities through the sieve holes of the upper tiers 4 and 11 are sent respectively on the lower tiers of sieves 7 and 13 of sieve mills 2 and 10.
