Description

Technical Field

[0001] The utility model relates to the technical field of agricultural equipment, in particular to an agricultural seed screening and classification device. Background Art

[0002] In order to improve the quality of seeds, it is usually necessary to screen the seeds. Seeds that are shriveled, deformed, large or small are not conducive to cultivation. Various problems are likely to occur during the planting process, such as low germination rate, low survival rate, poor drought and flood resistance, etc. Therefore, only by screening out seeds with moderate particle size for planting can the planting efficiency of crops be effectively guaranteed.

[0003] Although seeds with moderate particle size are conducive to mechanized sowing, the most common screening method is mostly traditional manual screening. By observing the seeds, the person will select the seeds that meet or do not meet the requirements one by one according to their own judgment of the fullness and size of the seeds to be screened. Manual seed screening will result in low efficiency, high labor intensity, and often problems of missed screening and misscreening, resulting in the presence of small particles and other unqualified seeds in large particles, which directly affects the later planting results.
