Description

Technical Field

[0001] The utility model relates to the field of seed screening, and more specifically, to a seed screening and impurity removal device. Background Art

[0002] In some grain growers and collectors and feed processing plants, wheat, rice, corn, soybeans, cotton seeds and various oil seeds generally need to be screened to remove various impurities and dust in the grain or oil seeds, such as dust, debris, rotten grain, pebbles, leaves, chaff, dust and shriveled grain.

[0003] Existing screening devices mainly include air separators and vibrating screens. Although air separators can screen materials of different weights, they are difficult to screen out impurities with a weight similar to that of seeds. Vibrating screens can screen materials of different volumes, but are difficult to screen out impurities with a volume similar to that of seeds. Therefore, existing seed screening devices still have the problem of incomplete screening, and impurities will remain. Utility Model Content

[0024] Among them, an inclined plate 101 is obliquely arranged at the bottom of the inner cavity of the device box 1, and the bottom of the inclined plate 101 is docked with the discharge port 14, and a switch group 102 is fixedly arranged on the front of the device box 1. A connecting rod 301 is fixedly connected to the side of the screening bucket 3 close to the fixed frame 4, and the connecting rod 301 movably penetrates the fixed frame 4 and extends to its inner cavity. A connecting plate 302 is fixedly connected to the inner end of the connecting rod 301, and the connecting plate 302 is connected to the inner wall of the fixed frame 4 through a contracted spring 303, and the spring 303 is also sleeved on the outside of the connecting rod 301. A collecting plate 501 docked with the upper end of the screening bucket 3 is fixedly arranged at the top of the inner cavity of the device box 1, and the collecting plate 501 is connected to the outside of the collecting box 5 through a collecting pipe 502. The bottom of the collecting plate 501 is evenly arranged with air nozzles 504 connected to the collecting pipe 502, and the outside of the collecting pipe 502 is also fixedly arranged with an exhaust fan 503 connected to the inner cavity. The power end of the motor 8 movably passes through the fixed seat 6 and extends to the inner cavity of the plug-in frame 7, and the power end of the motor 8 is fixedly connected to a turntable 801, and half of the outer surface of the turntable 801 and the inner walls on both sides of the plug-in frame 7 are provided with mutually meshing latches 802. The inner wall of the device box 1 located at the bottom of the screening bucket 3 is rotatably connected to a rotating shaft 11, and a spring telescopic pin 12 and a toothed disc 13 are provided on the outer fixed sleeve of the rotating shaft 11. The spring telescopic pin 12 is in a stretched state by default and contacts the bottom of the screening bucket 3, and the toothed disc 13 and the rack 10 are meshed with each other.

[0025] Based on the above structure, when the device is in use, the staff fills the seeds through the feed port 2, and then starts the motor 8 and the exhaust fan 503 through the external switch. The motor 8 drives the turntable 801 at the power end to rotate, and uses the outer half of the latch teeth 802 to drive the latch teeth 802 on both sides of the plug-in frame 7 to engage in sequence, thereby driving the plug-in frame 7 to reciprocate in the fixed seat 6. When the plug-in frame 7 moves inward, its inner end abuts against the screening bucket 3 to move horizontally. At this time, the screening bucket 3 moves horizontally and drives the outer connecting rod 301 to move horizontally together. In the process of moving the connecting rod 301, the spring 303 will be stretched and contracted. When the plug-in frame 7 moves back outward, Under the elastic contraction force of the spring 303, the screening bucket 3 can be driven to move back. In this way, with the reciprocating movement of the plug-in frame 7, the screening bucket 3 can also be driven to move horizontally and reciprocally for screening. On the other hand, when the plug-in frame 7 moves back and forth, the connecting rod 9 connected to the inner end will also drive the rack 10 at the bottom to move back and forth, and then the rack 10 is engaged with the toothed disc 13 on the outside of the rotating shaft 11, and drives the rotating shaft 11 to rotate back and forth. While the rotating shaft 11 rotates, the spring telescopic pin 12 on its outside contacts the bottom of the screening bucket 3 in turn, and the elastically stretched spring telescopic pin 12 contacts its bottom in turn and vibrates up and down, so that the seed screening in the screening bucket 3 is more thorough. Based on this, during the entire screening process, the fixed small dust particles in the seeds are screened and fall into the inner cavity of the device box 1 and slide through the inclined inclined plate 101 to the discharge port 14 for collection, while the seeds remain in the screening bucket 3, and the box door of the box 1 can be opened later to take them out. Some broken shells of seeds can be extracted by the exhaust fan 503, and then extracted by the collection tube 502 and the air nozzle 504 at the bottom of the collection plate 501 and temporarily stored in the collection box 5, and can be cleaned up later. In summary, the combination of wind selection and oscillation screening can achieve a relatively thorough screening and impurity removal operation for seeds.
