Technical Field

[0001] The utility model relates to the technical field of crushed material grinding, in particular to a crushed material destruction and grinding tool assembly. Background Art

[0002] There are high requirements for the destruction of scraps. These sites need to ensure that the scraps cannot be restored or reassembled to protect the security of information. Therefore, in certain cases, the scraps need to be ground to convert them into powder to ensure the complete destruction of information. The grinding of scraps usually involves the use of grinding tool assemblies.

[0003] There are already some chip grinding tool assemblies on the market, but they have some disadvantages. First, traditional tool assemblies are prone to wear and tear, and the blades need to be replaced frequently, resulting in low production efficiency. Second, the existing tool assemblies have limited applicability to different types of chippings and cannot meet the requirements of different particle sizes and shapes. In addition, some tool assemblies also have problems such as excessive chipping dust and high motor power, which is not conducive to environmental protection.

[0004] Therefore, it is necessary to provide an improved crushing material destruction grinding tool assembly to solve the above problems. The utility model aims to provide a wear-resistant tool assembly suitable for a variety of crushing material types, with low dust emission and low motor power, so as to improve the efficiency and quality of destruction, meet the relevant crushing technology requirements, and reduce the impact on the environment.

[0018] The utility model provides a crushed material destruction grinding tool assembly, which solves the problems of tool damage, low production efficiency, high motor power and environmental disadvantages in the prior art.

[0019] The motor drives the small pulley to rotate through the belt through the large pulley, which increases the speed and reduces the torque, reducing the power of the motor. The small pulley drives the rotation of the cutter, and the cutter is easy to disassemble and maintain. The pre-crushed and destroyed debris falls into the knife barrel through the feed port, and the debris can be formed into powder through the bite of the cutter and the toothed knife. Then the powdered debris is thrown into the discharge port box through the discharge port. The grinding process causes the powdered debris to have a higher temperature. At this time, it is cooled by the discharge port radiator to avoid the risk caused by high temperature and the emission of polluting gases. The utility model has a simple structure, energy saving and low emission, and high production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
