In-place heat regeneration asphalt pavement remixer

Abstract

The invention relates to an earth heat regenerate pitch road mixer, which comprises: a frame, a material hopper, a sprayer, a transfer hopper, a hot air cycle heater, a regenerator, a laying device, a front bridge, a back bridge, a cabin, a control system and a power system, wherein the material hopper, sprayer, transfer hopper, hot air cycle heater and regenerator are fixed on the frame; the material hopper via the new pitch front transfer device is connected to the transfer hopper; the laying device comprises a regenerated pitch mixing laying device and new pitch mixing laying device; the outlet of continuous feeding device is connected to the inlet of regenerated pitch mixing laying device; the transfer hopper via the new pitch horizontal transfer device is connected to the inlet of new pitch mixing laying device. The invention has simple operation and high automatic degree.

Description

technical field [0001] The invention mainly relates to the field of asphalt pavement maintenance machinery and equipment, in particular to an in-situ heat regenerated asphalt pavement remixer. Background technique [0002] Asphalt pavement has the advantages of stable driving, comfortable, low noise, convenient maintenance, and easy recycling. In domestic and foreign highways and urban roads, asphalt pavement is widely used as the main structure type of high-grade pavement. Asphalt pavement recycling technology is based on its It can protect the environment, reduce the development of new resources, save road maintenance costs and other significant social and economic benefits, and has been more and more developed and applied. [0003] Asphalt pavement regeneration technology cold regeneration and hot regeneration, hot regeneration is divided into hot in situ regeneration and field mixing hot regeneration, hot in situ regeneration of asphalt pavement can use 100% of the origi...

Problems solved by technology

The second type of complete set of equipment cannot complete paving by itself, and must be equipped with a paver. At the same time, even if equipped with a paver, it cannot complete the resurfacing function of simultaneously realizing double-layer paving

[0006] The defects of the heating machine and the remixing machine in the first type of in-situ heat regeneration complete set of equipment are that, firstly, the infrared heating fuel refined propane is not produced in China and must be imported from abroad; secondly, for the severely damaged asphalt pavement, infrared radiation When heating the road surface, it is easy to cause the road surface to overheat, and form a large amount of harmful smoke, polluting the environment: third, the infrared radiation heater is the same as the atmosphere when heating the road surface, and the road surface is more oxidized, whic
