Technical Field

[0001] The utility model relates to the technical field of agricultural planting, in particular to a planting and screening device for agricultural planting. Background Technique

[0002] A seed is a structure formed by the fertilization of the ovule of a seed plant. Generally, it consists of a seed coat, an embryo, and endosperm, etc. The embryo is the most important part of the seed and grows into a new individual after germination. The endosperm contains nutrients. Seeds are the reproductive system of seed plants and play an important role in continuing the species. In the process of agricultural planting, a screening device is often needed to screen the planting seeds to increase the planting success rate.

[0003] At present, there are still some deficiencies in the use of the current agricultural planting seed screening device. For example, the utility model patent with the publication number CN212093213U discloses a seed screening device for agricultural planting. The above patent can only perform a single-program screening through a filter plate, and its screening effect is poor, which is not convenient for the effective screening of agricultural planting seeds.
