Paver ironing device with cleaning function

Abstract

The invention provides a paver ironing device with a cleaning function. The left side of an ironing plate main body is connected with a left side oil cylinder through a left force application component. The right side of the ironing plate main body is connected with a right side oil cylinder through a right force application component. The middle of the ironing plate main body is connected with a middle oil cylinder through a force application component. A cleaning storage heating tank is arranged on one side of the ironing plate main body. A cleaning heating device is arranged on the inner side of the cleaning storage heating tank. A circulating pump is arranged on one side of the bottom of the cleaning storage heating tank. The cleaning storage heating tank is connected with cleaning liquid pipes through the circulating pump. The cleaning liquid pipes are provided with liquid inlet valves. The cleaning liquid pipes are arranged at the bottom end and the top end of the ironing plate main body. Cleaning spraying heads are arranged on the cleaning liquid pipes evenly and are of a hollow structure with a semicircular cross section. The cleaning spraying heads are provided with cleaning holes. A temperature sensor is arranged in the middle of the ironing plate main body. The paver ironing device has a very good cleaning effect. The conditions of pavement scratching during second paving and a rough surface are 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 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 of the upper...

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.
