A box structure of a single-shaft shredder

Abstract

The invention discloses a box body structure of a single-shaft shredder. The box body structure is characterized in that a shredding cavity is formed inside on end of a box body; a material pushing mechanism is arranged at the other end of the box body, and comprises a material pushing plate, a guiding device and a first driving device; the guiding device comprises two first guiding strips and two guiding wheel assemblies; the two first guiding strips are fixedly arranged on two sides of the box body respectively, and extend along the direction close to the shredding cavity; the guiding wheel assemblies are fixedly connected with the material pushing plate; each guiding wheel assembly comprises two first guiding wheels and a second guiding wheel; each first guiding strip is clamped between the two corresponding first guiding wheels; one first guiding wheel is in rolling fit with the top end of the corresponding first guiding strip; the other first guiding wheel is in rolling fit with the bottom end of the corresponding first guiding strip; and each second guiding wheel is positioned on and in rolling fit with the inner side of the corresponding first guiding strip. By adoption of the box body structure disclosed by the invention, the material pushing plate can be prevented from shaking up and down or from side to side, thereby ensuring stable material pushing process operation of the material pushing plate and achieving high material dropping efficiency.

Description

technical field [0001] The invention relates to the technical field of material processing equipment, in particular to a box structure of a single-shaft shredder. Background technique [0002] Single-shaft shredder refers to a shredder with a single knife roller. There are multiple moving knives fixed on the knife shaft, and fixed knives are fixed in the corresponding box. When the driving mechanism drives the knife roller to rotate, the movement of the knife shaft The knife rotates around the central axis of the knife shaft. During the rotation of the moving knife, the blade of the moving knife will cut the material together with the blade of the fixed knife and tear the material into pieces. When crushing, the single-shaft shredder pours the material to be crushed into the box from the feed port on the box, and pushes the material into the crushing cavity under the action of the pushing plate in the box, so that the material Shearing, extrusion and tearing are carried out...

AI Technical Summary

Problems solved by technology

However, the operation of the pushing plate inside the box of the existing shredder is often not smooth enough, and it is easy to get stuck during the pushing process, and it is easy to shake during the pushing process, resulting in low blanking efficiency
