Hand pushing type layered cutting recycling machine for asphalt concrete pavement

Abstract

The invention discloses a hand pushing type layered cutting recycling machine for an asphalt concrete pavement. The layered cutting recycling machine is composed of a trolley frame, a joint cutting knife combined structure and a layered cutting knife combined structure, wherein the trolley frame is provided with a power supply, a circuit control board, loading driving equipment, heating equipment,radar range finding equipment and a walking braking system; the joint cutting knife combined structure is used for cutting longitudinal and transverse joints of all surface layer thicknesses; the temperature, intensity and depth in a joint cutting process are adjusted in real time through the circuit control board; then the layered cutting knife combined structure realizes longitudinal cutting and recycling of cut block-shaped asphalt concrete surface layers, and the temperature and intensity in a cutting process are adjusted in real time through the circuit control board. The layered cuttingrecycling machine disclosed by the invention can realize layered recycling of the asphalt concrete surface layers and effective utilization of old asphalt concrete materials is improved; no noises, dust and vibration are generated, and damages to a previous pavement are not caused; secondary pollution is not caused. Furthermore, the recycling machine has the advantages of relatively small volumeand convenience for operation and can be flexibly applied to various fields.

Description

technical field [0001] The patent of the present invention relates to an asphalt concrete pavement layered cutting equipment, which can realize the layered cutting and recovery of asphalt concrete pavement, so as to make full use of recovered RAP materials to prepare high-performance recycled asphalt concrete. Background technique [0002] At the end of 2013, statistics showed that China's cement concrete pavements were mainly used in low-grade roads in townships and villages. Among the 104,000 km of expressway pavements, only 3,452.8 km of cement concrete pavements accounted for only 0.19%, and the proportion of asphalt concrete pavements was 99.81%, compared with the mileage of cement concrete pavement and asphalt concrete pavement, it is almost negligible. Compared with cement concrete pavement and other pavements, asphalt concrete pavement has the advantages of convenient construction and maintenance, good driving comfort, prolonging the service life of tires, saving fue...

AI Technical Summary

Problems solved by technology

[0007] The milling machine breaks the old asphalt mixture layer through the milling rotor, causing damage to the constituent materials of the asphalt mixture, and the aggregate is refined; patent number CN201710806599.1, although through the milling depth control device and the milling depth adjustment device, The milling depth of the road surface can be adjusted, but the milling rotor breaks the structural layer through high-speed rotation, so the upper, middle and lower layers of the asphalt concrete road cannot be well stratified. In addition, the milling depth adjustment device is set in sections It cannot be adjusted at any depth, and the milling depth of the milling rotor is also limited, and the lower layer cannot be milled in place at one time.
