Mechanical device for screening away seed impurities

Abstract

The invention discloses a mechanical device for screening away seed impurities. The mechanical device comprises a vehicle body. The bottom of the vehicle body is provided with a set of universal wheels. A supporting plate is installed at the bottom of a supporting screw rod. A set of steel channel supporting rods and a set of support plate supporting rods are connected to the upper portion of thevehicle body. The top ends of the steel channel supporting rods are welded to steel channel. The tops of the support plate supporting rods are welded to a support plate. A motor frame is welded to oneside of the steel channel supporting rods. A gear motor is installed on the motor frame and matched with an eccentric wheel. The eccentric wheel is connected with one end of a screening frame througha connection rod, the two sides of the screening frame are each detachably connected with a set of sleeve base, the sleeve bases are matched with rolling wheels through springs, and a wave block is welded to the interior of a channel of the steel channel. The mechanical device for screening away the seed impurities is convenient to move, easy to operate, capable of working after being powered on,capable of screening away impurities in seeds and good in screening effect, screening motion has a shaking effect, the scraping and winding amount of impurities on a screening net can be effectivelyreduced, and the screening effect is enhanced.

Description

Technical field [0001] The invention relates to the field of agricultural mechanical devices, in particular to a mechanical device for screening seed impurities. Background technique [0002] In agricultural production, it is necessary to screen out impurities such as stalks in seeds during seed recovery. In screening work, mechanical sieving devices are commonly used for screening. Large-scale mechanical sieving devices currently in use are costly and inconvenient to move. , The noise pollution is large, and it is very inconvenient when small batches of seeds are sieved. A low-cost, flexible operation, and convenient for the individual screening of small batches of seeds is needed to facilitate the seed screening. . Summary of the invention [0003] The object of the present invention is to provide a mechanical device for screening seed impurities to solve the problems raised in the background art. [0004] In order to achieve the above objective, the present invention provides t...

Problems solved by technology

[0002] In agricultural production, impurities such as stalks in seeds need to be screened out during seed recycling, and mechanical screening devices are generally used for screening during the screening work. The large-scale mechanical screening devices currently used are expensive and inconvenient to move , the noise pollution is large, and it is very inconvenient when sieving small batches of seeds. Now a low-cost, flexible and convenient seed sieving device for individual sieving of small batches of seeds is needed to provide convenience for seed sieving.
