A turntable 9 is fixedly connected to the output end of the 8. An adjusting rod 10 is rotatably connected to one side of the turntable 9. A crossbar 11 is rotatably connected to the end of the adjusting rod 10 away from the turntable 9. A vertical plate 6 is fixedly connected to the top surface of the bottom plate 1. One end of the crossbar 11 slides through the vertical plate 6 and extends to the other side and is fixedly connected to one side of the box body 3. A screening plate 13 is fixedly connected inside the box body 3. The box body 3 is driven to move back and forth through the reciprocating assembly, which in turn drives the screening plate 13 to move back and forth, thereby improving the efficiency of seed cleaning and screening.

[0028] The buffer assembly includes multiple shock absorbers 17 fixed between the connecting plate 14 and the placement plate 16. Each shock absorber 17 is fitted with a spring 18, and the two ends of the spring 18 are fixed to the bottom surface of the placement plate 16 and the top surface of the connecting plate 14, respectively. The buffer assembly can reduce the occurrence of seed breakage due to collision with each other in the collector due to impact force, and can also reduce the wear or damage to the collector caused by impact force. At the same time, it can also absorb the noise generated when the seeds fall. Multiple screening holes are opened on the screening plate 13. Sliding grooves 15 are opened on both sides of the top surface of the bottom plate 1. The support rod 12 is slidably connected in the corresponding sliding groove 15. The top surface of the box 3 is connected to the feed pipe 5, and the feed pipe 5 is connected to the sealing cover 1.

[0029] Working principle: Agricultural seeds are poured into the housing 3 through the feed pipe 5, and are cleaned and screened by the screening plate 13. By starting the motor 8, the motor 8 drives the turntable 9 to rotate, the turntable 9 drives the adjusting rod 10 to move back and forth, the adjusting rod 10 drives the crossbar 11 to move back and forth, and the crossbar 11 drives the housing 3 to move back and forth. At this time, the screening plate 13 can be driven to move back and forth, thereby improving the efficiency of seed cleaning and screening. When it is necessary to collect the screened seeds, the seed collector is placed on the placement plate 16, the sealing cover 2 on the discharge pipe 4 is opened, and the seeds are collected. When the seeds fall, they will generate impact force. The shock absorber 17 and the spring 18 will be compressed to generate reaction force, thereby buffering the impact and reducing the occurrence of seed breakage due to collision with each other in the collector. It can also reduce the wear or damage to the collector caused by the impact force. At the same time, the setting of the shock absorber 17 and the spring 18 can also absorb the noise generated when the seeds fall.
