Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a roadbed stone crushing device for highway construction. Background Art

[0002] During the construction of the road, it is necessary to lay gravel to strengthen the road. Generally, large gravel requires a crushing device. Stone crusher is suitable for crushing and shaping soft, medium-hard and extremely hard materials. It is widely used in various ores, cement, refractory materials, bauxite clinker, corundum and various metallurgical slags.

[0003] Among them, a stone crushing device for highway roadbed construction disclosed in application number CN201920481134.8 is also an increasingly mature technology. The staff rotates the handle to drive the screw to rotate. Since the screw is threadedly connected to the inner wall of the shell, the screw is prompted to move outward under the action of the rotational force of its own outer wall thread, and under the limiting action of the slider, the screw drives the U-shaped plate to move left and right, and drives the right crushing roller to move left and right through the third rotating shaft, thereby changing the distance between the left and right crushing rollers, so that the staff can adjust the crushing degree of the highway roadbed construction stones according to needs, without the need for secondary crushing, thereby improving processing efficiency.

[0004] A dust removal crusher disclosed in CN202120027027.5 is retrieved and is also an increasingly mature technology. When the crusher is working, the water pump is started so that the water in the clean water tank is continuously supplied to the water inlet pipe, so that the atomizing nozzle sprays in the dust collecting box; at the same time, the exhaust fan is started so that the dust-containing gas at the feed port and the discharge port is sucked into the intake pipe, and then flows into the wet dust removal box for spraying and dust removal, which has the effect of improving the dust pollution generated during the crusher processing.

[0005] However, the above two types of devices still have the following defects in actual use:
