Inclined soybean impurity removal device

The utility model relates to the technical field of soybean processing, and discloses an inclined soybean impurity removal device which comprises a mounting frame, a screening box mounted at the top of the mounting frame and a feeding hopper mounted on the outer wall of the mounting frame, a filter plate is fixedly connected to the inner wall of the screening box, and a plurality of fixing blocks are fixedly connected to the outer walls of the two sides of the screening box; according to the soybean impurity removal device, through the arrangement of the air inlet pipe, the fan and the impurity removal pipe, light soybean shells and empty soybeans in soybeans are separated from the soybeans under the action of wind power generated by the fan and fly out of the feeding hopper through the impurity removal pipe, and therefore primary impurity removal of the soybeans is achieved; and then through mutual cooperation of a vibration motor, a spring and a fixing block, the screening box vibrates on the mounting frame
