Building waste treatment device

The utility model belongs to the technical field of building waste treatment equipment, and discloses a building waste treatment device which comprises a crusher main body, a feeding mechanism capable of screening waste entering the crusher main body is mounted on the upper surface of the crusher main body, and exhaust holes are formed in the upper surface of the feeding mechanism. A dust removal mechanism is installed in an exhaust hole of the feeding mechanism, a groove is formed in the lower surface of the feeding mechanism, a supporting mechanism is inserted into the groove of the feeding mechanism, and waste entering the crusher body is filtered and screened through the feeding mechanism, so that the waste large in size cannot enter the crusher body; therefore, the time consumed when the crusher main body crushes the waste is shortened, and the treatment efficiency of the waste treatment device is improved; and dust generated in the using process of the crusher main body is filtered and discharged throug
