The present application relates to the technical field of
road construction equipment, and particularly relates to a
cement pavement breaking device, which comprises a multi-hammer
crusher main body, a hydraulic oil cylinder arranged on the surface of the multi-hammer
crusher main body, a support plate arranged at the end of the hydraulic oil cylinder, and a breaking and shearing device arranged between the support plate and the multi-hammer
crusher main body. The device adopts a secondary
impact design of
metal block and
metal hammer column, and can realize twice high-intensity beating in a single drop, so that the
cement slabs can be quickly broken to the standard particle size of the regeneration construction, the construction time is shortened, the
impact is concentrated, the broken pieces are uniform, the secondary
processing is reduced, the cost and manpower are reduced, the
impact air pressure is used to drive the worm gear and the
cam to rotate, the
cutting plate is automatically driven to reciprocatingly stretch and contract, the ground is sheared, no additional driving components are needed, the pavement is broken more uniformly through the composite breaking of beating and shearing, the
cam vibration can also loosen the base layer, and the stability of the roadbed and the
bearing capacity of the pavement are improved.
