Sweet potato grading screening device capable of reducing damage

Abstract

The invention discloses a sweet potato grading screening device capable of reducing damage. The sweet potato grading screening device comprises a base plate. The sweet potato grading screening deviceis characterized in that support legs are arranged on the outer wall of the top of the bottom plate, and a screening box is welded to the outer walls of the tops of the support legs; a concave hole isformed in the outer wall of the top of the screening box, a feeding hopper is welded to the inner wall of the concave hole, and a baffle is arranged on the outer wall of one side of the screening box; a vertical plate is welded to the outer wall of the top of the baffle, inclined rods distributed at equal intervals are arranged on the outer wall of one side of the vertical plate, the outer wallsof the inclined rods are rotationally connected with screening rollers, and inclined plates are correspondingly welded to the outer wall of one side of the vertical plate and the inner wall of one side of the screening box; and a fixing plate is arranged on the inner wall of one side of the screening box, and an ear seat is welded to the outer wall of the top of the fixing plate. By the adoption of the sweet potato grading screening device capable of reducing damage, fast screening of sweet potatoes with different sizes is effectively achieved, the screening effect is better, the buffering effect on the sweet potatoes can be achieved, it is effectively guaranteed that damage to the sweet potatoes in the screening process is avoided, and the sweet potato grading screening device capable ofreducing damage is more practical.

Description
