Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a crop seed cleaner. Background Technique

[0002] Seeds themselves are the basis for the development of the agricultural industry, and excellent seeds play a crucial role in the final harvest.

[0003] After being damaged, the nutrients inside the seeds show different degrees of deficiency, which also affects the emergence rate and the growth status during the seedling stage. Before sowing the seeds, it is necessary to perform wind screening on the seeds, so seed screening equipment is required.

[0004] When using traditional screening equipment, during screening, the feeding amount of seeds is related to the wind force. If more seeds fall through the discharge port and the wind force is small, it is impossible to blow out the impurities inside the seeds well. Therefore, it is necessary to adjust the amount of seeds falling. The traditional adjustment method is to first turn the adjustment nut and rotate the release plate to change the angle between the release plate and the feeding port, and then reverse the rotation of the adjustment nut and fix it to control the feeding amount. However, in this process, both hands are required for operation, which is inconvenient and it is impossible to adjust the release angle of the release plate very conveniently.
