Technical Field

[0001] The utility model relates to the technical field of crop seed screening, in particular to a device for multiple selection of crop seed particles. Background Art

[0002] Crops refer to various plants cultivated in agriculture, including food crops, cash crops, etc. Edible crops are the basic food source for humans. Before planting crops, it is usually necessary to screen the size of the seeds to ensure the quality of the seeds planted subsequently, and then improve the survival rate and yield of the seeds. Therefore, it is particularly important to screen out seeds that pass quality inspection, are plump, and have uniform seed diameters before planting, and to remove bad seeds.

[0003] Usually, in the process of seed screening, the seeds are first placed on a filter net, and holes of different diameters are opened on the filter net. The seeds are passed through the holes to screen the seeds. When the seeds are placed on the filter net during the screening of large quantities of seeds, the seeds will accumulate and the accumulated seeds cannot pass through the holes. As a result, the selection equipment cannot screen the seed quality, and many of the screened seeds will still be unqualified. For this reason, we propose a multiple selection equipment for crop seed particles. Utility Model Content
