The working principle of the utility model is:

Start the motor, and the rotating shaft drives the crushing chain and the crushing blade to rotate. Materials with high water content and high viscosity are fed into the cylinder from the feeding port, and the crushing chain in the cylinder crushes the larger materials initially, reducing the direct impact damage of large materials on the knife plate, and the crushing knife plate in the cylinder Small materials are precisely crushed. Through the cooperation of the crushing chain and the crushing blade, the crushing effect on materials with high water content and high viscosity is improved.

When the material tends to stick to the wall, start the left and right electric cylinders, so that the piston rods of the left and right electric cylinders move up and down, and then through the action of the horizontal bar, the transmission rod and the ring scraper frame, the scraper blade is pushed along the inner cylinder. Scrape the wall up and down to achieve the purpose of clearing the wall. Then the purpose of continuous and high-efficiency operation of the equipment is realized.

The utility model selects suitable crushing chains and layers of crushing blades according to the state of materials and the granularity and fineness of discharge. During production, the high-speed rotating shaft drives the crushing chain and the crushing blade to rotate at a high speed, and collides violently with the materials coming in from the feeding port. After multiple layers of collisions, the materials can be broken.

Since the inner cylinder is made of mirror stainless steel with a thickness greater than 3mm, the chance of material sticking to the wall is also reduced.

The utility model has the following advantages:

The utility model improves the crushing effect on materials with high water content and high viscosity through the compound use of the crushing chain and the crushing knife plate, improves the wall cleaning effect through the wall cleaning mechanism, realizes continuous and efficient operation of the equipment, low failure rate, and The situation is stable and meets the needs of enterprises.
