Double-layer paver ironing device with cleaning function

Abstract

The invention provides a double-layer paver ironing device with a cleaning function. An outer layer ironing plate is connected with an ironing plate body through a fixing plate, a rotating device is arranged on the fixing plate, rotating rods are arranged on the outer layer ironing plate, rotating shafts are arranged on the outer side of the fixing plate, the left side of the ironing plate body is connected with a left oil cylinder through a left force exerting component, the right side of the ironing plate body is connected with a right oil cylinder through a right force exerting component, the middle of the ironing plate body is connected with a middle oil cylinder through a force exerting component, a cleaning and storage heating tank is arranged on one side of the ironing plate body, a cleaning heating device is arranged on the inner side of the cleaning and storage heating tank, a circulating pump is arranged on one side at the bottom of the cleaning and storage heating tank, a liquid inlet valve is arranged on a cleaning liquid pipe, cleaning spray heads are arranged on the cleaning liquid pipe, cleaning holes are formed in the cleaning spray heads, and a temperature sensor is arranged in the middle of the ironing plate body. The double-layer paver ironing device has a very good cleaning effect, the situation that a pavement is scratched when paving is carried out again, and consequently a roughened surface occurs is avoided, and thus the paving quality is improved.

Description

technical field [0001] The invention relates to the field of road surface operation machinery and equipment, and more specifically relates to a double-layer paver ironing device with a cleaning function. Background technique [0002] As the core working device of the asphalt paver, the ironing plate directly determines the paving quality and performance of the machine. At present, the ironing plate of asphalt paver at home and abroad all adopts a rectangular box structure welded by steel plates, and the bottom is fixed with a wear-resistant bottom plate by bolts. When paving hot mix asphalt mixture, the base plate of the ironing plate of the paver will be heated to a high temperature above 130°C, while the upper part of the ironing plate box is at ambient temperature. Due to the large temperature difference between the top and bottom of the ironing plate box structure, the expansion of the lower part of the ironing plate at high temperature is much larger than the expansion...

AI Technical Summary

Problems solved by technology

Due to the large temperature difference between the top and bottom of the ironing plate box structure, the expansion of the lower part of the ironing plate at high temperature is much larger than the expansion of the upper part of the ironing plate at low temperature. The decrease of pavement flatness has seriously affected the quality of road construction

[0003] When the asphalt pavement paver starts to work, if the ironing plate is not heated, the high-temperature asphalt material will stick to the cold ironing plate, and the road surface will be scratched and rough surface will appear during paving.
