Concrete asphalt ground ditcher

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a trencher for concrete asphalt ground. Background technique [0002] At present, it is often necessary to dig drainage ditches in road construction and municipal engineering construction, and it is also necessary to dig ditches in the process of laying pipes and cables. In front of manual excavation of hard ground, it is necessary to break the hard ground and remove the concrete or asphalt on the ground before excavating the soil layer. Manual breaking of hard ground is labor-intensive, time-consuming, costly, and inefficient. Existing chain trenchers, especially small trenchers, cannot dig trenches on hard ground, such as concrete and asphalt, due to the chain structure. Due to the limitations of chain trenchers, they can be used in many places Out of service. When renovating in some places, it is required to dig trenches on the local ground without damaging the ...

Problems solved by technology

[0003] Aiming at the deficiencies of the above-mentioned prior art, the purpose of the present invention is to propose a trencher for concrete asphalt ground, which solves the problem that the existing chain trencher cannot dig trenches on hard ground or partially dig trenches, and artificially break hard ground. High labor intensity, time-consuming and labor-intensive, high construction cost and low work efficiency
