Seed screening device for agricultural experiment seedling

Abstract

The invention discloses a seed screening device for agricultural experiment seedling. The seed screening device comprises a screening box; a first motor is arranged on the inner wall on one side of the screening box; a thread screw is arranged on the outer wall at one end of an output shaft of the first motor; a thread sleeve is connected onto the outer wall of the thread screw; an arc-shaped plate is arranged on the outer wall at the top of the thread sleeve; fixing plates are arranged on the inner walls on two side of the screening box; a sliding chute is formed in the inner wall on one sideof each fixing plate; two first pulleys are connected onto the inner wall at the bottom of each sliding chute in a sliding manner; supporting legs are arranged on the outer walls at the tops of the two first pulleys; and the outer walls at the tops of the supporting legs are separately connected with first connecting plates and second connecting plates. Air generated in an air blower is blown inthe screening box by means of an air outlet pipe, dried seeds can be effectively distinguished from full seeds under wind force, the seeds are effectively screened, the screening effect is good, and the working efficiency of people is improved.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a seed screening device for raising seedlings in agricultural experiments. Background technique [0002] Before the seeds are sown, in order to optimize the seeds, it is usually necessary to select large and full seeds for sowing. Especially for peanuts, corn, peas and other seeds, seeds with insufficient particle size and fullness not only have a low survival rate, but also due to genetic characteristics, the grown seedlings will bear relatively small fruits after planting. [0003] The Chinese patent authorization number is CN201721520845.9, which discloses a high-efficiency seed screening device, which is characterized in that it includes a base (1), a vibrating motor (2), a box (3), a feeding hopper (4), a turning Plate (5), counterweight (6), fan (8), vibrator (9), impurity removal screen (10), impurity outlet (11), first vibrating sieve (12), first material outlet (...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problems in the prior art that the seeds are not cleaned before the seeds are screened, resulting in a decline in the screening quality.
