A method for on-site complete crushing of road cement pavement and a pavement crusher

Abstract

The invention provides a pavement crusher and a method for on-site complete crushing of road cement pavement. The pavement crusher includes: a frame, an oil tank, a driving mechanism, a crushing mechanism and a lifting mechanism, wherein the fuel tank is fixedly arranged with the frame; the driving mechanism is installed On the frame, it includes an engine connected to the oil tank and a hydraulic system driven by the engine; the crushing mechanism is installed on the frame and located below the frame, including a knife drum for crushing the road surface, and the knife drum is controlled by the hydraulic system. Control the crushing work; the lifting mechanism includes a side plate arranged on the side of the knife drum, and a front lifting frame and a rear lifting frame connected to the side plate and arranged symmetrically front and rear with respect to the side plate; the side plate is controlled by a hydraulic system to lift; road crushing The front wheel and the rear wheel of the machine are installed on the front lifting frame and the rear lifting frame respectively. The invention has the advantages of being directly crushed into stones meeting repair requirements without being broken into small plates, high in crushing efficiency, and suitable for high-strength plates.

Description

technical field [0001] The invention relates to the technical field of road crushing, in particular to an on-site complete crushing method for road cement pavement and a crusher. Background technique [0002] At present, there are several ways to repair the damaged road cement pavement: one is to use a pick machine to break the road surface into small plates, and then transport the broken plates out of the pick machine and re-transport them to New The raw materials that meet the stone grading screening repair requirements are repaired. This method is costly and does not meet the requirements of resource recycling. The other is to break the pavement into small pieces with a pickaxe machine, and then use a crusher (usually a tractor-mounted mobile crusher) to crush the pre-demolition small pieces so that they meet the stone material grading screening repair requirements . This method has extremely high requirements for the pre-crushing of the cement pavement, and the side l...

AI Technical Summary

Problems solved by technology

This method has extremely high requirements for the pre-crushing of the cement pavement, and the side length of each small plate of the original cement pavement is required to be less than 30cm; and the efficiency of this method is low, and the crushing area per day is less than 500 square meters; and encounter Cement slabs containing steel bars or high-strength slabs above C30 cannot be broken and can only be shipped directly
