An agricultural planting seed screening device capable of conveniently and quickly discharging residues

Abstract

The invention particularly discloses an agricultural planting seed screening device capable of conveniently and quickly discharging residues. The device comprises a screening barrel. A supporting screw rod is rotationally arranged in the screening barrel along the central axis of the screening barrel; a filter screen arranged in the screening barrel in an up-and-down sliding manner is in threadedconnection with and sleeves the supporting screw rod through a supporting threaded sleeve located in the middle of the filter screen; a supporting block fixedly sleeves the supporting threaded sleeve;the supporting block is connected with the middle of the filter screen through an elastic supporting piece; the bottom end of a rotating column is rotatably connected with the top end of the supporting screw rod; at least one arc-shaped material stirring rod is fixedly mounted on the outer ring of the bottom of the rotating column; and the concave surface of the arc-shaped material stirring rod faces the direction opposite to the rotating direction of the rotating column. According to the embodiment of the invention, the screening effect of the filter screen can be ensured by virtue of the liftable filter screen and the started vibration motor, and the waste residues on the upper surface of the filter screen can be continuously pushed to move towards the outer ring by virtue of the rotating arc-shaped material stirring rod, so that the filtered residues can be conveniently discharged out of the screening barrel.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a seed screening device for agricultural planting which facilitates rapid discharge of residues. Background technique [0002] Seeds play a vital role in the growth of agricultural crops. Only good seeds can grow good crops. In agricultural production, seed selection often determines the growth of crops in the future. However, when selecting crops, we will use Relevant screening tools are used for seed selection, but the screening effect is not very satisfactory. After screening, the residual residue on the filter screen is inconvenient to clean up. Generally, it will be cleaned manually, which will further increase the labor intensity. Contents of the invention [0003] The object of the present invention is to provide a seed screening device for agricultural planting that facilitates the rapid discharge of residues, so as to solve the problems raised in the abov...
