The utility model relates to the technical field of
traffic engineering, in particular to an earthwork crushing device for
traffic engineering construction, which comprises a bracket, a jaw
crusher, a feeding frame, a blanking frame, a mounting frame, a first hydraulic rod and the like, a jaw
crusher is connected to the support, a feeding frame is connected to one side of the jaw
crusher, a discharging frame is connected to the bottom of the jaw crusher, a mounting frame is connected to the side, away from the feeding frame, of the jaw crusher, and a first hydraulic rod is connected to the mounting frame. The first hydraulic rod, the buffer
assembly and the hydraulic
impact hammer are arranged, large earthwork is knocked at
high frequency through the hydraulic
impact hammer, so that large hard earthwork, stone-containing soil
layers or concrete blocks are directly crushed, the material blocking problem is rapidly solved, the hydraulic
impact hammer can accurately act on a blocking point, and the blocking effect is good. And invalid disturbance of a traditional material pushing or vibrating mode to the blocked material earthwork is avoided, the blocked material treatment efficiency is improved, manual intervention cleaning is not needed, and the
safety risk of operators is reduced.
