Agricultural seed screening device

Abstract

The invention is applicable to the technical field of agriculture, and provides an agricultural seed screening device. The agricultural seed screening device comprises a first screening chamber, and aconnecting shaft; a screening box in an inverted circular truncated cone shape is rotationally arranged in the first screening chamber; a first screen is arranged on the side wall of the screening box; the connecting shaft is hollow; one end of the connecting shaft is fixedly connected with the top of the screening box and communicates with the interior of the screening box; the other end of theconnecting shaft is arranged on the outer part of the first screening chamber and is provided with a feeding port; a material guiding piece is mounted in the first screening chamber; the material guiding piece is in a circular truncated cone shape and is hollow; the bottom face of the screening box is attached to the top face of the material guiding piece; a discharging opening is formed in the bottom of the screening box; an electric valve is arranged on the discharging opening; a second screen is arranged below the discharging opening in a sliding mode; a vibrating mechanism for driving thesecond screen to vibrate is further arranged; the part, close to the second screen, of the first screening chamber communicates with a second screening chamber with an opening in the upper end througha material guiding pipe; and an air blower is fixed to the side, opposite to the material guiding pipe, of the screening chamber. According to the embodiment, the seed screening effect can be improved, and the seed screening quality is improved.

Description

technical field [0001] The invention belongs to the field of agricultural technology, in particular to an agricultural seed screening device. Background technique [0002] Agricultural seeds refer to all plant organs that can be directly applied to sowing in agricultural production. Before sowing, the seeds need to be screened to remove impurities and shriveled seeds in the seeds. An important premise; in modern agriculture, seed screening machines have become indispensable equipment, which effectively improves agricultural production efficiency while reducing manpower input; however, the screening effect of the currently used seed screening devices is not good, and the screening efficiency is low Low, and can not completely remove the seed husks and shriveled seeds in the seeds, resulting in poor screening quality, and even directly affect the growth quality of crops in the later stage. Contents of the invention [0003] The purpose of the embodiments of the present inve...
