Concrete crusher for municipal administration road construction

Abstract

The invention discloses a concrete crusher for municipal administration road construction. The concrete crusher comprises a machine shell, wherein baffles are symmetrically arranged on the left and right sides of the bottom of the machine shell, the space between the two baffles is sleeved with a wheel shaft, walking wheels are arranged on the wheel shaft, the wheel shaft sleeves fixed bearings arranged at corresponding positions of the baffles and stretches out of the baffles and is sleeved with a driven belt wheel; and the machine shell is sleeved with a driving belt wheel. The concrete crusher provided by the invention is skillful in structural construction and reasonable in layout; the walking wheels are arranged in a wheel disc manner or a toothed plate manner, so that the concrete crusher can conveniently walk on crushed rugged mountain roads; the piston is pushed by a push rod to repeatedly compress air, a crushing head is driven to repeatedly hammer downwards, meanwhile, a vertical sleeve is stressed to rotate so as to drive the crushing head to rotate through a movable sleeve, and two motions are combined, so that a concrete pavement can be efficiently crushed. Compared with a traditional crushing manner of an excavator, the concrete crusher has the advantages that the cost is low, and the working efficiency is high.

Description

technical field [0001] The invention relates to the technical field of municipal construction equipment, in particular to a concrete crusher for municipal road construction. Background technique [0002] In 2010, China's urban population reached 666 million, accounting for 49.68%; the population living in rural areas was 674 million, accounting for 50.32%. Compared with 2000, the urban population increased by 207 million, the rural population decreased by 133 million, and the proportion of urban population increased 13.46 percent. Moreover, from the perspective of the scale of urbanization in China, both the annual net increase and the total urban population have long been ranked first in the world. The total urban population of China is twice the total population of the United States, and 1 / 4 larger than the total population of the 27 EU countries. [0003] Over the next two decades, the world's cities will expand at an unprecedented rate and scale. This series of urbani...

Problems solved by technology

[0005] At present, during the construction of municipal road projects, it is often necessary to dismantle the original damaged concrete pavement. The traditional demolition method is to load a pick on the excavator and carry out punching and crushing. This crushing method is costly and has low crushing efficiency.
