Seed screening device for agricultural seeding and working method of seed screening device

Abstract

The invention relates to a seed screening device for agricultural seeding and a working method of the seed screening device and belongs to the technical field of seed screening. One end of a dustpan plate is connected with stand columns, the other end of the dustpan plate is connected with an alternative box and a vertical reciprocating mechanism, the vertical reciprocating mechanism and the standcolumns are connected with a left-and-right reciprocating mechanism, the left-and-right reciprocating mechanism is connected with a support, the alternative box is matched with a garbage can and a threaded cover or an air drying mechanism, and the threaded cover is provided with a filtering screen and is connected with a drainage pipe. Seeds to be screened are put on the dustpan plate, a first motor is started to drive the dustpan plate to reciprocate vertically to blow away light impurities, the alternative box is filled with water, a second motor is started to drive the dustpan plate to reciprocate left and right until the seeds enter the alternative box, blighted seeds enter the garbage can, a control valve of the drainage pipe is turned on, a third motor is started, the threaded coveris screwed down, and the full seeds fall into the air drying mechanism. According to the seed screening device for agricultural seeding and the working method of the seed screening device, multiple screening procedures are arranged, screening is more thorough, the blight seeds can be directly screened out at the same time, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a seed screening device for agricultural sowing and a working method thereof, belonging to the technical field of seed screening. Background technique [0002] Seed, the propagule unique to gymnosperms and angiosperms, which is formed by pollination and fertilization of ovules. The seeds are generally composed of three parts: the seed coat, embryo and endosperm. The mature seeds of some plants only have two parts, the seed coat and the embryo. Such crops are all developed from seeds, but because the seeds contain impurities such as seed coats and weeds, the seeds need to be screened. At this time, a screening device is needed, but the existing screening devices have low working efficiency. Impurities in the seeds cannot be completely removed, and unsaturated seeds cannot be screened out, which reduces the quality of the seeds. Contents of the invention [0003] In order to solve the problems in the background technology, the...
