The beneficial effect that the utility model has:

There is a pusher, which can push the material in the feeding box to the direction of the rotor, without manual feeding, and realizes continuous production, and will not be blocked in the feeding box due to too much material. In addition, when the pusher pushes the material, it swings, which reduces the floor space compared with the pusher moving in the horizontal direction; and the hydraulic arm is used to push the pusher to swing, and the hydraulic arm is driven by the hydraulic device, and the power is sufficient. , and more stable and durable. The hydraulic device is installed inside the frame, which not only saves space but also protects the hydraulic device, and is easy to replace and maintain.

The moving knife has a cubic structure, and a groove is provided on one surface, which is beneficial to improve the recovery efficiency; and only part of the four sharp corners on the moving knife are used for shredding work, and generally only one sharp corner protrudes from the rotor The outer surface is involved in the shredding work, so if the sharp corner is damaged, just turn the movable knife, which realizes the alternate use of the four sharp corners, increases the service life of the movable knife, and saves costs.

The rotor is provided with an anti-winding knife protruding from its outer surface. There is a blade around the anti-winding knife. The function of the anti-winding knife is to prevent the material from winding on the surface of the rotor, affecting its shredding effect and even damaging the machine.

Each row of moving knife concave holes on the surface of the rotor is arranged in a "V" shape, so each row of moving knives on the rotor is also arranged in a "V" shape. When shredding, the material can slide from both sides to the center. It is beneficial to solve the blind spot of cutting, can completely shred all the materials, improve the shredding efficiency, and reduce the friction between the materials and the two side walls of the machine, prevent the materials from being stuck with the machine, and improve the service life of the equipment.

The rotor is driven by a low-speed, high-torque reduction mechanism, and the power is stronger.
