Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a crushing device for building construction engineering construction. Background Art

[0002] Construction waste refers to the slag, abandoned soil, abandoned materials, silt and other wastes generated during the construction, laying, demolition and repair of various buildings, structures, pipe networks, etc. by construction units or individuals. According to the source of generation, construction waste can be divided into engineering slag, decoration waste, demolition waste, engineering mud, etc.; according to the composition, construction waste can be divided into slag, concrete blocks, crushed stones, brick and tile fragments, waste mortar, mud, asphalt blocks. Construction waste needs to be crushed by crushing equipment.

[0003] A construction waste crushing device with a Chinese authorized announcement number of CN212348882U, in which both the two grinding wheels and the motor can rotate with the rotation of the bracket, thereby changing the position of the two grinding wheels, and placing them horizontally when processing short construction waste, and placing them vertically when processing long waste, to prevent the long waste from falling out. During rotation, the worm drives the turbine to rotate, and the worm gear has a self-locking function to prevent the worm gear from driving the worm to rotate. The worm wheel is fixedly connected to the rotating shaft, and the rotating shaft is rotatably installed on the box body. The worm wheel is meshed with the worm on all sides, and different worms are mutually transmitted through the first bevel gear. When one worm is rotated, the other worms rotate synchronously. The surroundings of a worm wheel are meshed with multiple worms, so that the worm wheel is subjected to balanced force, with more force points, thereby improving the stability of the bracket.

[0004] There are still certain shortcomings in its use. When crushing construction waste, only a single crushing will reduce the comprehensiveness of the waste crushing, and there will easily be dead corners of crushing. At the same time, dust will be generated when crushing construction waste. The dust will be emitted into the air and cause air pollution, thereby reducing the environmental friendliness of the crushing equipment when it is used. Utility Model Content
