[0002] At present, with the vigorous development of my country's road traffic, various viaducts and culverts are gradually increasing, providing great convenience for vehicle travel; during the construction of bridges and tunnels, a large number of stones will be generated, so the stones need to be crushed and recycled.

[0003] After searching, the Chinese patent number CN218689914U discloses a stone crushing device for bridge and tunnel construction, which belongs to the field of crushing devices, including: a crushing box; a crushing device, which is arranged on the crushing box; a feeding barrel, which is fixedly connected to the feeding port of the crushing box; a water sprinkling mechanism, which is arranged on the feeding barrel; a dust prevention mechanism, which is arranged on the feeding barrel; and a lower hopper, which is fixedly connected to the feeding port of the feeding barrel. The utility model can realize water spraying through the arrangement of a spray pipe, and the water spraying through the spray pipe can suppress the generation of dust, so that dust-free is achieved during the crushing process. The dust discharge can be blocked by the arrangement of a partition, thereby realizing double protection and preventing dust discharge. The fixed plate can be moved by extending the electric telescopic rod, and the partition can be moved by moving the fixed plate. The problem that the stone crushing device in the prior art cannot suppress the generation of dust during crushing, which will cause a large amount of dust to be generated during crushing, can be solved.

[0004] However, during the crushing process, the existing crushing device has a crushing head that contacts the stone for a long time, and the surface will be contaminated with a lot of dust and mud, which not only affects the appearance, but also causes the sharp edges and corners of the crushed blocks to be covered with mud. The long-term lack of a cleaning structure will also affect the use of the crushed blocks and reduce work efficiency. Based on this, the utility model designs a stone crushing device for bridge and tunnel construction to solve the above problems. Utility Model Content
