Broken stone spreader for road construction
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.
本发明一种道路施工用碎石撒布机，属于道路修建技术领域，撒布器为两组，前后平行设置于行走机架上，并借助配套驱动装置沿行走机架左、右滑动形成撒布宽度调节结构；撒布器采用分隔料仓结构，碎石借助接料仓的绞龙均匀的落至落料仓出料口处，然后在旋转布料辊的带动下，拨料板拨动碎石经出料口撒向地面，每次的带料量为两拨料板之间的容积。旋转布料辊外周均布有拨料板和与其内孔相通的漏尘孔，旋转布料辊的两相邻拨料板与出料口的弧形底托板接触配合形成封闭空间，该封闭空间借助弧形底托板上的除尘孔与设置在行走机架上的除尘器连通。在碎石撒布的同时吸掉碎石表面粉尘，增加碎石与沥青的裹附强度，保证施工质量，减少粉尘污染。
