In-place heat regeneration integrated machine for bituminous pavements and control method

Abstract

The invention provides an in-place heat regeneration integrated machine for bituminous pavements and a control method, wherein the in-place heat regeneration integrated machine for bituminous pavements integrates the functions of pavement milling-planing, bituminous mixture heating, remixing and the like. The regeneration integrated machine comprises a chassis, a milling-planing device, a conveyor, a conveyor heating device, an agitating pan, agitating pan heating devices, and a control system, wherein the conveyor is located behind the milling-planing device, the conveyor heating device is located above the conveyor, the agitating pan heating device is arranged at the top of the agitating pan, and the control system is used for controlling the travelling speed of the chassis, the heating temperature, the mixture metering and the agitating time of the agitating pan. The control method comprises the following steps: starting to accumulate travelling pulses, and if a required travelling distance reaches, switching a material distribution board to the other side; if the material distribution board is overturned, opening an agitating cylinder on the other side, discharging for a period of time, and waiting for the next switching of the material distribution board; and repeating the steps until the machine stops working.

Description

technical field [0001] The invention belongs to the technical field of construction machinery, and in particular relates to an in-situ thermal regeneration integrated machine for asphalt pavement and a control method. Background technique [0002] At present, most highways in my country discard a large amount of milling materials in the process of asphalt pavement maintenance, which not only destroys the environment, wastes resources, but also increases costs. Recycling of old asphalt pavement can relieve pressure on resources, be beneficial to environmental protection and reduce maintenance costs. After years of systematic research, developed countries in Europe and the United States have formed a relatively complete set of recycling technologies, which have reached a mature level of standardization and standardization. Some countries have issued corresponding policies and regulations, mandating that waste asphalt pavement materials must be recycled. In China, due to t...

AI Technical Summary

Problems solved by technology

[0004] At present, hot-in-place recycling equipment at home and abroad can be roughly divided into two categories: one is the combination mode of "heating machine + milling machine + remixing machine". Complete, the equipment has a single function, takes up a lot of space during construction, consumes a lot of manpower and material resources, and the distance between the milling device and the receiver of the remixer is relatively large, the heat loss of the milling material is serious, and the mixing and paving of the mixture The other type is the road mixing type, which uses the milling wheel to complete the road surface milling and mixing of the mixture at the same time. Its main problem is that the mixing time of the mixture is short, the heating cannot be heated during the mixing process, and the recycled material is not heated sufficiently. , uneven mixing, difficult to guarantee the quality of recycled pavement
