The invention discloses a concrete
asphalt ground ditcher which comprises a frame, a power device, two walking mechanisms, a
cutting and crushing device, a ditching and soil separating device and a hydraulic
system. The two walking mechanisms are symmetrically arranged on the two sides of the frame, and the power device is connected with the walking mechanisms. The ditching and soil separating device is arranged on the rear side of the vehicle body. The
cutting and crushing device is arranged at the front end of the frame through a front supporting frame and comprises a transmission shaft, a crushing
assembly and a
cutting blade. The transmission shaft is connected with the power device through a first
transmission belt. The cutting blade is arranged on the cutting blade driving shaft, andthe cutting blade driving shaft is connected with the front supporting frame through the cradle. The crushing
assembly comprises a sleeve, an
impact rod and an eccentric wheel, the
impact rod is vertically and movably arranged below the transmission shaft through the sleeve, an
impact head is arranged on the lower end thereof, and the eccentric wheel is arranged on the transmission shaft. The concrete
asphalt ground ditcher is reasonable in structural design, capable of cutting and crushing firstly and then digging quickly, adjustable in ditching depth, capable of achieving deep digging and replacing manual ditching, time-saving, labor-saving and high in working efficiency.
