Description

Technical Field

[0001] The utility model relates to the technical field of seed selectors, in particular to a crop seed selector. Background Art

[0002] The grading and selection machine is a machine specially used for screening seeds. It has precise screening accuracy and efficient screening ability, which can effectively improve the quality of seeds, enhance the resistance of seeds, and increase the yield of seeds.

[0003] When the existing seed selection device is grading and screening seeds, if the seeds are poured into the feed port at one time, when a certain number of particles are accumulated, due to factors such as gravity and increased friction, these particles directly below the pipe output port will accumulate together to form block-like objects, causing blockage inside the pipe or equipment, affecting the daily operation of the device. If the seeds are poured in batches, the workload will increase and the working efficiency of the device will be reduced. For this reason, we propose a crop seed selection machine.
