Description

Breaker for engineering Technical Field The utility model relates to the field of crushing equipment, in particular to a crusher for engineering. Background A large amount of construction waste is often generated in the process of building removal, and for the treatment of the construction waste, a crusher is adopted to crush the construction waste and then transport the construction waste outwards in part of working conditions, especially in some projects containing more materials such as wood, composite materials, metal frames (doors, windows and roofs) and the like, the compressibility of direct transportation of the construction waste part (in a rod shape or a sheet shape) is poor, so that the transportation efficiency of a bicycle is low, and the construction waste is required to be crushed and transported on site. At present, during the engineering construction, the construction waste is mostly treated by a crawler chassis moving jaw crushing device as disclosed in the patent with publication number CN220759413U and the patent with publication number CN118385019B, and the crusher is mostly suitable for the working condition of concrete construction waste, and the feeding hopper is mostly provided with an inclined screening vibration feeding structure. The applicant found that when the construction waste is crushed against the aforesaid working conditions, in order to facilitate the part of the waste in the form of a rod or a sheet to enter the crushing cavity, the top of the crushing cavity is opened, and the waste is splashed outwards after the elastic potential energy is easily accumulated in the process of re-extrusion or shearing crushing of the waste, for example, the equipment in the patent with publication number CN118385019B, the splashed waste not only increases the difficulty of cleaning on site, but also causes potential safety hazards to site equipment and operators.
