[0003] The existing screening device cannot adjust the screening speed. When screening different seeds, different screening speeds are needed. The screen of the general screening device is fixedly installed, which fixes the angle of the screen and leads to fixed screening efficiency. If you want to change the screening speed, you need to replace the screening device, which increases the use cost, reduces the practicality and applicability, and has poor screening quality. Generally, when the screening device screens seeds, the seeds are loaded through the feed hopper. The seeds are piled together on the surface of the screen. Therefore, it is difficult to separate the seeds and impurities during screening, so that the seeds move together with the impurities, which affects the screening quality and reduces the practicality. In order to solve the above problems, we propose a seed screening equipment for crop breeding. Utility model content
