Single-shaft shredder

Abstract

The invention discloses a single-shaft shredder which comprises a box body, a tool assembly and a material pushing mechanism. A crushing cavity is formed in one end of the box body. The tool assembly comprises a fixed tool, a plurality of movable tools and a tool shaft, and the tool shaft is pivoted to the interior of the crushing cavity. The multiple movable tools are installed on the outer surface of the tool shaft. The fixed tool is fixedly arranged on one side of the crushing cavity. The fixed tool and the outer surface of the tool shaft are arranged in a spaced mode, and a cutting gap is formed. The material pushing mechanism comprises a material pushing box and a first driving device, and the first driving device is used for driving the material pushing box to move towards the crushing cavity. The end, close to the crushing cavity, of the material pushing box is fixedly provided with a plurality of material pushing strips, and the end faces, close to the crushing cavity, of the material pushing strips are provided with arc-shaped grooves matched with the outer circumference of the tool shaft. By the adoption of the single-shaft shredder, the blanking efficiency is improved, and the crushing efficiency of materials is improved.

Description

technical field [0001] The invention relates to the technical field of material recovery, in particular to 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 in the crushing chamber, so th...

Problems solved by technology

However, in the working process of existing shredders, when there are many or heavy materials, generally a large thrust is required to send the materials into the crushing cavity, and during the material pushing process, the thrust mechanism and the rotating There is often a large gap between the moving knives, not only the blanking efficiency is low, but also the moving knives cannot fully and fully contact with the material, resulting in low crushing efficiency
