Agricultural bean grain reciprocating screening device

Abstract

The invention discloses an agricultural bean grain reciprocating screening device which comprises a feeding box and a screening barrel. A partition is arranged inside the feeding box and divides the inside of the feeding box into a feeding chamber positioned at the left end and a discharging chamber positioned at the right end, the screening barrel is provided with a backflow port communicated with the feeding chamber, the backflow port is positioned on the inner side of a screening net barrel, the side wall of the screening barrel is communicated with the discharging chamber through a guide pipe, a first discharging port is arranged on the side wall of the discharging chamber, a second discharging port is arranged on the side wall of the bottom of the feeding chamber, and a bottom baseplate is arranged on the lower side of the feeding box and connected with the feeding box through multiple damping devices. The device is simple in structure; a screw conveyor is uniform in bean grain lifting, thereby being uniform in screening, so that the circumstance that screening effect is bad due to simultaneous screening of many grains is avoided; repeated screening can be realized, so that screening effect is improved; feeding from the top end is avoided during feeding, so that labor is saved.

Description

technical field [0001] The invention relates to agricultural mechanical equipment, in particular to a reciprocating screening device for agricultural bean particles. Background technique [0002] Agricultural machinery refers to various machinery used in crop planting and animal husbandry production, as well as in the primary processing and handling of agricultural and animal products. Agricultural machinery includes agricultural power machinery, farmland construction machinery, soil tillage machinery, planting and fertilization machinery, plant protection machinery, farmland drainage and irrigation machinery, crop harvesting machinery, agricultural product processing machinery, animal husbandry machinery and agricultural transportation machinery, etc. Agricultural machinery in a broad sense also includes forestry machinery, fishing machinery, and rural sideline machinery such as sericulture, beekeeping, and edible fungus cultivation. However, the existing agricultural bean...

AI Technical Summary

Problems solved by technology

However, the existing agricultural bean particle screening device needs to inject the material into the screening device from the top when screening, which increases the labor force. While causing blockage, the screening effect is not obvious due to the simultaneous screening of a large number of bean particles
