Description

Technical Field

[0001] This utility model relates to a cleaning device, specifically a cleaning device for maize hybrid seeds, belonging to the field of seed processing technology. Background Technology

[0002] The processing of corn seeds mainly includes drying, threshing, cleaning, coating, film forming, weighing and packaging. As we all know, crops rely on seeds for reproduction and growth, and seed quality has a direct relationship with crop growth and yield. Therefore, selecting good seeds is the key to growing good crops. Seed cleaning refers to sieving out shriveled and unripe seeds according to standards to improve seed quality.

[0003] Chinese patent application publication number CN215029949U discloses a corn seed flotation gravity cleaning machine. This invention, through a cleaning mechanism, uses a first rotary motor to drive a spiral stirring blade via a first power output shaft. The corn and brine in the cleaning tank are stirred and mixed. After the brine and corn settle, a crank handle drives a gear to rotate, preventing workers from inhaling dust and thus ensuring seed quality.

[0004] Although the solutions in the aforementioned patents do not generate dust during cleaning, the cleaning machines in those patents are not convenient for simultaneously screening large and small particles of debris mixed into the seeds. Most cleaning devices can only clean larger or smaller debris individually, resulting in low efficiency in cleaning corn seeds. Therefore, a corn hybrid seed cleaning device is proposed here.

The bottom end of the limiting rod slides through the second connecting plate and the screening shell in sequence and extends to the outside of the screening shell.

This allows for the initial screening of the corn seeds on the surface of the coarse filter frame 4, and larger impurities are discharged into the first collection box 5 through the first slag discharge port 3. The screened corn seeds then enter the surface of the fine filter frame 7 for further screening. Finally, through the cooperation between the second positioning plate 93, the second sliding rod 96, and the second spring 98, the corn seeds are further screened. The coordination between the two allows the second connecting plate 97 to move, which in turn moves the fine filter frame 7. The fine filter frame 7 can further screen smaller impurities inside the corn seed. After screening, the corn seed enters the second collection box 8 through the fine filter frame 7, which can simultaneously filter both large and small impurities inside the corn seed, improving the screening efficiency. The screened impurities fall onto the inner bottom wall of the screening shell 1, and then the second motor 135 is started. Through the coordination between the second motor 135, the transmission rod 136 and the moving shaft 137, the transmission plate 131 can move on the bottom surface of the screening shell 1. Through the coordination between the transmission plate 131, the first connecting rod 133 and the second connecting rod 134, the cleaning plate 12 can move, and at the same time clean the impurities on the inner bottom wall of the screening shell 1, improving the cleanliness of the inside of the cleaning device.
