Description

Technical Field

[0001] The utility model relates to the technical field of cement block crushing, in particular to a cement block crushing device. Background Art

[0002] At present, in construction, cement block crushing technology is often used to deal with discarded cement blocks for reuse or treatment. It mainly breaks the block solid material into several pieces for subsequent treatment or use. According to the size of the material after crushing, the crushing can be divided into coarse crushing, medium crushing and fine crushing. In cement production, crushing is one of the indispensable links. Through crushing, cement clinker and various admixtures can be fully mixed to improve the strength and durability of concrete.

[0003] The authorization announcement number in the prior art is: CN108435292B, and the name is a cement block crushing and recovery device for construction, including a bottom plate, a right frame, a crushing frame, a filter, a bearing seat, a rotating rod, a roller, crushing teeth, a connecting rod, a servo motor, a fan gear, a mounting column and a first fixed sleeve and other components. The combination of these components enables the patent to effectively avoid splashing of debris, prevent blockage, and completely collect the crushed cement blocks. The right end of the bottom plate is connected to the right frame, and the upper left side of the right frame is connected to the crushing frame. The bottom wall of the crushing frame is equipped with a filter. In addition, the lower parts of the left and right walls of the crushing frame are connected to the bearing seat.

[0004] However, during the use of this patent, only a single roller is used to crush the waste cement blocks in the equipment, and its crushing efficiency is relatively low. When processing a large number of waste cement blocks, it may take a long time to complete the crushing task. The roller bears a large load, which will cause serious wear and tear on the equipment. Secondly, during the crushing process, vibrations may cause damage to the equipment itself and surrounding facilities. In the long run, this will increase the maintenance and replacement costs of the equipment. The vibrations generated during the crushing process may cause the equipment to shift when crushing materials, resulting in poor crushing effects, which in turn affects work efficiency.
