Description

Technical Field

[0001] The utility model relates to the field of asphalt concrete pavement waterproofing, in particular to a spraying device for a waterproof asphalt concrete pavement waterproof layer. Background Art

[0002] Asphalt pavement waterproofing refers to various types of pavement paved with road asphalt materials mixed into mineral materials. Asphalt binder improves the ability of paving aggregate to resist damage to the road surface caused by traffic and natural factors, making the road surface smooth, dust-free, impermeable and durable. Therefore, asphalt pavement waterproofing is the most widely used advanced pavement in road construction.

[0003] Before laying waterproof asphalt pavement, waterproof coating needs to be sprayed or brushed on the pavement to play a waterproof role. When laying, the coating will be placed in a coating box for easy transportation and spraying. However, during the spraying process, the sticky coating on the inner wall of the box cannot be fully utilized, resulting in waste. Moreover, it will settle at the bottom of the box over time, which will reduce the quality of the coating and cause troubles in later maintenance. Utility Model Content

[0011] Preferably, the dust collector head is fixed to the lower end of the mobile vehicle.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model stirs the paint in the tank by arranging a stirring mechanism in the storage tank to prevent the paint from settling at the bottom of the tank and causing uneven quality during spraying; and scraper stirring frames are provided at the upper and lower ends of the rotating shaft in the built-in stirring mechanism, which are used to scrape off the paint adhered to the inner wall of the tank while stirring, thereby reducing the need to clean the inside of the pipe after the paint is sprayed, and preventing the paint from adhering to the tank and not being fully utilized; before spraying the paint, the dust suction head at the bottom of the mobile vehicle removes debris such as leaves fallen on the road surface, and the debris gathers in the dust suction box for subsequent processing, and the dust removal mechanism is used in conjunction with the device to improve the practicability of the device.

[0014] The utility model installs a rotating base at the lower end of the spray head. When the spray head is adjusted to a suitable height, the rotating base drives the lifting rod to rotate, and then the dispersion pipe rotates. Because the rotating base will be restricted by the sliding groove during rotation, the rotation angle is restricted to prevent excessive rotation and spraying onto other mechanisms. The rotating base and the lifting rod cooperate with each other to effectively improve the spraying effect of the device when spraying paint. BRIEF DESCRIPTION OF THE DRAWINGS
