AI Technical Summary
Technical Problem
Existing crushers cannot effectively crush large pieces of concrete slabs and concrete columns, and cannot separate the steel bars in construction waste, resulting in the steel bars damage to the crusher.
Method used
设计了一种地铁路基用再生填料粉碎设备，包括破碎机和预破碎装置。预破碎装置由机架、下压油缸、破碎锤、推送架和推送油缸组成，用于预破碎大块建筑废料，并通过推送架和永磁板分离钢筋。
Benefits of technology
Effective pre-crumbing and secondary crushing of concrete slabs and concrete columns is achieved, solving the problem that existing crushers cannot crush large pieces of construction waste, and separating the steel bars to avoid the steel bars from damaging the crusher.

Abstract
The regenerated filler crushing equipment for the subway subgrade comprises a crusher and a pre-crushing device, and the pre-crushing device is mainly composed of a rack, a pressing oil cylinder, a crushing hammer, a pushing frame and a pushing oil cylinder; the rack is provided with a horizontal workbench connected with an inlet of the crusher, the pressing oil cylinder is fixed above the horizontal workbench, and the crushing hammer is installed at the telescopic end of the pressing oil cylinder and used for pre-crushing large building waste; the pushing oil cylinder is used for pushing the pushing frame to horizontally reciprocate on the workbench, and the pre-crushed building waste is pushed into an inlet of the crusher. According to the recycled filler crushing equipment, large building waste such as concrete slabs and concrete columns can be pre-crushed, then pre-crushed stones are pushed into the crusher for secondary crushing, and the problem that an existing crusher cannot crush the large building waste is solved. In addition, steel bars in the building waste can be separated out through the regenerated filler crushing equipment, and the situation that the steel bars enter the crusher and then damage the crusher is avoided.
