Double-shaft shredding machine with material pressing device

Abstract

The invention discloses a double-shaft shredding machine with a material pressing device. The double-shaft shredding machine comprises a rack, a hopper, a cutter roller set, a material pressing plate, a hydraulic cylinder, a supporting frame and a connecting frame; the cutter roller set is mounted on the rack, the hopper is fixed to the rack, a discharging opening of the hopper is vertically opposite to the cutter roller set, one end of the material pressing plate stretches into the hopper and faces the cutter roller set, the other end of the material pressing plate is hinged to a piston rod of the hydraulic cylinder, and a first hinge axis is formed; the end, away from the material pressing plate, of a cylinder body of the hydraulic cylinder is hinged to the rack, one end of the connecting frame is hinged to the other end of the material pressing plate, and a second hinge axis is formed; the first hinge axis and the second hinge axis are separated, the other end of the connecting frame is hinged to the supporting frame, and the supporting frame is fixed to the rack; solid wastes can be conveniently, rapidly and stably pressed, the materials are not easily popped out of the tool shearing range, and the cutter roller set can conveniently and effectively shear and shred the materials.

Description

technical field [0001] The invention relates to a shredder, in particular to a double-shaft shredder with a pressing device. Background technique [0002] The double-shaft shredder, also known as the shear shredder, is a machine that shreds materials through the rotary shearing of the knife roller, so that the shredded materials can be reused conveniently. Among them, the material is generally solid waste. However, the solid waste to be shredded is usually relatively large in size, even spherical or cylindrical in shape, and has a smooth and elastic appearance, such as crude oil barrels and chemical barrels. Therefore, when such solid waste enters When the knife roll is used, it is difficult to cut and tear due to the smooth point of force. The commonly used method is to press down the material manually or through an auxiliary rod, so that the rotation of the knife roller can generate enough shearing force to apply to the waste material, which will inevitably bring certain...

Problems solved by technology

However, the solid waste to be shredded is usually relatively large in size, even spherical or cylindrical in shape, and has a smooth and elastic appearance, such as crude oil barrels and chemical barrels. Therefore, when such solid waste enters When the knife roll is used, it is difficult to cut and tear due to the smooth point of force

The commonly used method is to press down the material manually or through an auxiliary rod, so that the rotation of the knife roller can generate enough shearing force to apply to the waste material, which will inevitably bring certain dangers, and the force is unstable and less convenient.
