Sunflower seed length sorting combined type special-shaped nest hole mechanism

Abstract

The invention discloses a sunflower seed length sorting combined type special-shaped nest hole mechanism, and belongs to agricultural product primary processing equipment. N combined type special-shaped nest holes are formed in the inner wall face of a sorting roller, each combined type special-shaped nest hole is composed of a rectangular nest hole and a conical nest hole which communicate with each other, circular arcs are arranged at the transition connection positions between the rectangular nest holes and the inner wall face of the sorting roller and between the conical nest holes and the inner wall face of the sorting roller, the conical end portions of the conical nest holes are provided with circular arcs, the vertical wall faces of the two opposite sides, in the length direction, of the rectangular nest holes and the conical nest holes are inclined inwards in a mutual symmetry mode, the bottom wall faces of the conical nest holes are inclined upwards, on the inner wall face of the sorting roller, the length direction of the combined type special-shaped nest holes is the same as the rotating direction of the sorting roller, the rectangular nest holes are located behind the moving direction of the sorting roller, and the conical nest holes point to the moving direction of the sorting roller. The mechanism adapts to and meets the use requirements of sunflower seed length sorting operation, and is novel, unique and reasonable in structure, high in sorting operation efficiency and good in quality.

Description

technical field [0001] The invention belongs to primary processing equipment for agricultural products, and mainly relates to a sunflower seed sorting mechanism. Background technique [0002] The purchase standard of sunflower seeds is mainly calibrated according to the length of the seeds. According to this, socket sorting is currently the only effective method for sorting grains according to their length, and the most commonly used one is the socket cleaning machine, which presses the sockets on a metal plate, and then rolls the metal plate into a circle. The formed socket is used as a sorting operation part. During operation, after each sorting sunflower seed material enters the rotating socket, the seeds whose length and size are smaller than the diameter of the socket will fall into the socket and be filled with the socket. The eye cylinder rotates, and when it rises to the discharge height position, the sorted sunflower seeds filled in the socket will be discharged fr...

AI Technical Summary

Problems solved by technology

However, since the currently used sorting sockets are all hemispherical structures, it is found in the practice of sorting operations that the filling effect of the sunflower seeds filled in the hemispherical sockets is poor and unstable. When the sorted sunflower seeds Before reaching the height of the sorted sunflower seed collection tank, it has fallen off from the socket and cannot fall into the collection tank. The sorting efficiency is low and the sorting quality is poor.
