Description

Technical Field

[0001] The utility model relates to the technical field of seed impurity removal, in particular to agricultural seed impurity removal equipment. Background Art

[0002] Agriculture refers to an important industry in the national economy. It is an industry that produces food and industrial raw materials by cultivating animal and plant products. Agriculture belongs to the primary industry. Sowing is often required in agricultural planting. Before sowing, the seeds need to be screened and removed to increase the success rate of sowing.

[0003] For example, the utility model with the announcement number CN214600243U discloses a seed screening and impurity removal device for agricultural planting, including a screening box, a sector gear, a rack, a swing arm and a driving wheel. The bottom of the screening box is provided with a plurality of filtering holes, and an impurity collecting plate is placed below the screening box. The screening box is slidably connected to the main shaft surface embedded in the inner wall of the frame through the through hole opened in the side wall. The rack embedded in the top of the screening box is connected to the sector gear embedded in the bottom of the swing arm through the gear teeth. The middle part of the swing arm is connected to the longitudinal bracket through the shaft pin 1. By using the transmission principle of the synchronous belt, the servo motor 1 can drive the driving wheel to rotate. The shaft pin 2 can drive the swing arm to rotate by sliding in the slide groove while the driving wheel rotates, so that the swing arm and the sector gear can rotate around the shaft pin 1, thereby driving the rack and the screening box to move back and forth along the main shaft, realizing the function of automatically shaking the screening box to remove impurities in the seeds. Compared with the traditional method of manually shaking the screening box, the work efficiency is greatly improved.

[0004] However, during the seed screening process, there are often fine dust, fluff and insufficiently full seeds mixed in. If only vibration screening is used, it is easy for dust, fluff and insufficiently full seeds to be discharged from the full seeds, resulting in insufficient seed screening, thus affecting the success rate of sowing. For this reason, we propose agricultural seed impurity removal equipment. Utility Model Content
