Technical Field

[0001] The utility model relates to the technical field of stone crushing, in particular to a stone crushing and screening device. Background Art

[0002] With the improvement of urbanization, new buildings are being built every day. Stones are indispensable in the construction process. Some stones are too large to be used directly in construction. They need to be crushed first so that they can be used to prepare concrete, etc.

[0003] However, the existing stone crushing device has the disadvantage that it is difficult to improve the quality of the nearby air environment. When in use, a large amount of dust will be generated after the stone inside the device is crushed.

Moreover, the existing stone crushing device has the disadvantage that it is difficult to improve the quality of the crushed stone. When in use, some of the stones are still unqualified after the initial crushing, and the particles are large. They are directly used, resulting in a decrease in the quality of the crushed stone, which is not conducive to subsequent use. Utility Model Content
