Description
Technical Field
The invention belongs to the technical field of road construction, relates to a gravel spreading vehicle for constructing a road surface, and particularly relates to a gravel spreading vehicle with an adjustable spreading width and a dust removal device.
Background
The broken stone seal in road construction is composed of a thin asphalt bonding layer and a broken stone layer, and is a simple, efficient and economic pavement disposal technology; can play the roles of waterproof sealing and bonding, and can form a durable, anti-skid and dustproof wearing layer.
At present, pavement of broken stones is generally constructed by a vehicle-mounted spreader which is mounted at the tail of an automobile and used for spreading the broken stones along a road surface by taking the automobile as power. The spreading width is narrow, typically no greater than the width of the vehicle compartment, limited by the spacing between the left and right wheels of the vehicle. The spreading part generally adopts a roller friction feeding mode, and the crushed stones in the storage bin are freely dropped to the material door, then are fed to the material distributing groove by the rotating friction force of the roller, and then slide to the reflecting plate to fall. This construction has a limited spreading width due to the limited space design of the mechanical structure. Or the broken stones in the storage bin fall into the spreader through the discharging bin, then are uniformly distributed through the spiral in the spreader, then freely fall by gravity, and are sent to the reflecting plate by the rotating friction force of the roller through the material door to fall to the ground. Although the structure solves the problem of limitation on spreading width, the structure is easy to block and leak materials, and causes uneven spreading.
In addition, in order to ensure the surface wrapping strength of asphalt and gravel, the requirement of the gravel sealing technology on the gravel is very high. The macadam is used after being washed with water and dried by air. However, due to limited construction site conditions, it is difficult to ensure that the crushed stones can be washed and dried by water, and even if the crushed stones are rubbed with each other in the loading and transporting processes after being washed and dried by water, secondary dust, especially some relatively soft crushed stones, can be generated. The dust seriously affects the wrapping strength of the asphalt and the crushed stone, particularly when a seal coat is made, the bonding strength is small, and after the seal coat is rolled by a vehicle, stone is easy to fall off, so that the seal coat quality is seriously affected.
