Broken stone spreader for road construction

Abstract

The invention relates to a broken stone spreader for road construction, which belongs to the technical field of road construction, and is characterized in that two groups of spreaders are arranged ona walking rack in parallel front and back, and slide left and right along the walking rack by virtue of a matched driving device to form a spreading width adjusting structure; the spreader adopts a material bin separation structure, broken stones uniformly fall to a discharge port of a blanking bin by means of an auger of a material receiving bin, then, under the driving of a rotary material distributing roller, the broken stones are shifted by material shifting plates to be spread to the ground through the discharging port, and the material carrying amount of each time is the volume between the two material shifting plates. The material shifting plates and dust leaking holes communicated with inner holes of the material shifting plates are evenly distributed on the periphery of the rotarymaterial distributing roller, the two adjacent material shifting plates of the rotary material distributing roller are in contact fit with the arc-shaped bottom supporting plate of the discharging port to form a closed space, and the closed space is communicated with a dust remover arranged on the walking rack through dust removing holes in the arc-shaped bottom supporting plate. Dust on the surfaces of the broken stones is absorbed while the broken stones are spread, the wrapping strength of the broken stone and asphalt is improved, the construction quality is guaranteed, and dust pollutionis reduced.

Description

technical field [0001] The invention belongs to the technical field of road construction, and relates to a gravel spreading vehicle for road construction, in particular to a gravel spreading vehicle with an adjustable spreading width and a dust removal device. Background technique [0002] The crushed stone seal in road construction is composed of a thin asphalt adhesive layer and crushed stone layer. It is a simple, efficient and economical road surface disposal technology; it can play the role of waterproof sealing and bonding, and at the same time Can form a durable, non-slip and dust-resistant wearing layer. [0003] At present, gravel pavement is generally constructed by a vehicle-mounted spreader. The spreader is loaded at the rear of the car and powered by the car to spread gravel along the road surface. Limited by the distance between the left and right wheels of the car, the spreading width is narrow, generally not larger than the width of the carriage. The spread...
