Description

Technical Field

[0001] The utility model relates to the technical field of seed screening, in particular to a peanut seed rapid screening device. Background Art

[0002] The seeds of peanuts are peanut kernels. A peanut seed screening device is used when screening peanut seeds. Peanut seed screening is a common and relatively simple and direct way to improve the quality of peanut seeds. It is an important link in ensuring the seed quality in peanut production. Peanut seed screening has corresponding requirements for the fullness and particle size of peanut seeds. For example, a peanut seed quality screening device recorded in the patent with patent announcement number CN 217190846 U screens out peanut seeds of appropriate size through the setting of sieve plates and vibration motors.
