Crop seed screening equipment

Abstract

The invention discloses crop seed screening equipment and belongs to the technical field of agricultural mechanical equipment. The crop seed screening equipment comprises a rack, a feeding mechanism,a screening mechanism, a vibrating mechanism, a driving mechanism and a discharging mechanism, wherein the screening mechanism and the driving mechanism are arranged at the upper end of the rack; thevibrating mechanism is arranged below one end of the screening mechanism; the screening mechanism and the vibrating mechanism are connected with the driving mechanism; the feeding mechanism is arranged at the upper end of the screening mechanism; the screening mechanism comprises a screening component, two buffer components and a winnowing component; the winnowing component is arranged between thescreening component and the feeding mechanism; the feeding mechanism and the winnowing component are in transmission connection; and the two buffer components are mounted on the two sides of the screening component. The crop seed screening equipment is simple in structure and low in cost, can realize automatic screening operation, is suitable for being used by a common peasant household, can screen other crops through changing a first screening net and a second screening net with different meshes to enable the using range to be wider and further reduce the using cost.

Description

Technical field [0001] The invention relates to the technical field of agricultural machinery and equipment, in particular to a crop seed screening equipment. Background technique [0002] Before crop seeds are used, they must undergo a process of impurity removal, that is, wheat seeds mixed with straw and soil are screened to remove impurities. Traditional ordinary farmers will use manual screening methods, that is, use dustpans to pick up wheat seeds and stand on tiptoes, and use natural wind or electric fans to blow out the impurities. This is not only low efficiency but also labor intensive. In response to the above problems, many crop seed screening devices have appeared on the market to help ordinary farmers increase the speed of crop seed screening. [0003] The Chinese patent number CN105478355B provides a device for grain screening, including a base, a hopper, a vertical channel, an oblique channel, a fan, a swing plate, a swing rod, a bracket, and a transmission gear.

Problems solved by technology

[0005] First, when farmers use a dustpan to dump the grains for screening, they also use the wind to blow out the impurities in the grains for separation, and it needs to be repeated many times to completely clean up the impurities. It can be seen that the method of separating the impurities in the grains in this invention is also the same. Multiple repetitions are required, so the invention is less effective in sifting grain;

[0006] Second, the invention seems to have a simple structure, but if the setting of the lower magnet, gear, and rack L-shaped rack want to realize its function, it must be adjusted in details such as its connection method, resulting in a change in the structure of the entire device. It is complicated and increases the cost of equipment, which makes ordinary farmers unwilling to bear its use cost; and because of its complex structure, the replacement and maintenance of internal equipment requires professional operation, and ordinary farmers cannot handle it by themselves, which increases their maintenance costs. Therefore, making The invention cannot be popularized to ordinary farmers
