A sieve cage for wheat thresher

Abstract

The invention discloses a screen cage for a wheat scourer. The screen cage comprises a screen cage body; the screen cage body is formed by buckling two arc frames up and down; the screen cage body is wholly a cylinder structure; screens are arranged on the arc surfaces in the arc frames; a section of auxiliary polishing structure with a polishing strengthening effect on wheat is added at the left end part of the screen cage; the auxiliary polishing structure is formed by buckling upper and two arc cover plates, and is wholly a cylinder structure; resistance racks with arc plate structures are uniformly distributed on the arc surfaces of the inner sides of the arc cover plates; wave projection structures are arranged on the inner arc surfaces of the resistance racks; at least two wave projection structures are arranged on the inner arc surface of each resistance rack; the inner arc surfaces of the resistance racks are non-smooth surfaces; and the inner arc surfaces of the resistance racks are coated with emery layers through composite epoxy resins.

Description

technical field [0001] The invention belongs to the field of grain processing machinery, and in particular relates to a sieve cage for a wheat thresher. Background technique [0002] In the prior art, the threshing machine used for wheat cleaning has a relatively simple sieve cage structure, and the whole is a cylindrical sieve mesh structure. It is pushed sideways to the other side. During the pushing process, the wheat is struck by the plate and the collision between the wheat and the sieve is effected by the centrifugal force, and then the wheat is vibrated and cleaned. During this process, the moldy wheat or the large grain impurities mixed in the wheat can be crushed and discharged through the mesh of the sieve, and the high-quality wheat is discharged from the discharge end of the sieve cage for collection. [0003] However, in actual production, it is easy to find that the existing sieve cages cannot perform efficient and high-quality cleaning. The high-quality wheat...

Problems solved by technology

[0003] However, in actual production, it is easy to find that the existing sieve cages cannot perform efficient and high-quality cleaning. The high-quality wheat grains selected by existing equipment and methods still cannot achieve high-quality flour production. The main reason is The reason is that the existing equipment and methods are not thorough in the treatment of wheat impurities, and even the moldy particles cannot be effectively removed
