[0002] Ore crusher is a key equipment in mining projects. It can efficiently crush large pieces of ore into smaller particles to meet the needs of subsequent processing. It adopts advanced crushing technology, has strong crushing capacity and high stability, can handle ores of various hardnesses, adapt to different mining environments, is easy to operate, and can effectively improve production efficiency. Its importance is self-evident. It provides strong support for ore processing, promotes the continuous development of the mining industry, and plays an irreplaceable role in resource development and utilization.

[0003] In the prior art, there is a utility model with publication number CN219744978U. The utility model relates to the field of stone crushing, specifically a stone crushing device for construction, comprising a shell, one side of the shell surface is rotatably connected to a feed cover, one side of the shell surface is fixedly provided with a placement plate, the inner cavity of the shell is fixedly provided with a crushing roller body, the surface of the shell is fixedly provided with an organic shell, and the inner cavity of the shell is fixedly provided with a lifting mechanism; when the crushing roller body is used to crush the stone, the staff can use the lifting mechanism, under the action of the lifting mechanism, the pressing shell moves downward, and the stone is pressed by the pressing shell. The pressure on the top causes forced contact between the stone and the crushing roller body, avoiding idling between the stone and the crushing roller body and affecting the crushing of the stone. In addition, the staff can also use the dust suction mechanism to absorb the dust generated by the crushing to prevent the dust from spreading to the surrounding environment. However, after the stones are crushed, the sizes of the crushed stones are inconsistent. Therefore, in order to make the crushed stones of uniform size, a screen is installed at the discharge point in the existing technology. However, when the stones are screened by the screen, the screen is mostly fixed at the discharge point, which is easy to block the discharge port, resulting in low efficiency in discharge and screening of stones, requiring operators to frequently clear it, which consumes a lot of time.

[0004] In order to solve the problem that the size of the broken stones is inconsistent after the stones are crushed, in order to make the size of the broken stones consistent, a screen is installed at the discharge point in the existing technology. However, when the stones are screened by the screen, the screen is mostly fixed at the discharge point, which is easy to clog the discharge port, resulting in low efficiency in discharge and screening of stones, requiring operators to frequently clear the blockage, which wastes a lot of time. The existing technology adopts the method of installing a screen at the discharge point of the equipment to deal with the problem. However, after long-term use, the screen is easy to clog, which leads to poor discharge and separation effects of the equipment. Utility Model Content
