[0002] The sand and gravel crushing process generates dust, which can harm the health of on-site workers. Removing this dust has always been a challenging problem. Existing dry-process dust collectors can only collect dust generated at the point of generation, but are unable to remove dust that accumulates on equipment surfaces and platforms.

[0003] For example, "CN204262021U" disclosed in Chinese patent documents, with its announcement number, is a dust collection duct for plastic crusher dust collection, including a main pipe, a diverter joint and a trumpet-shaped dust collection hood. One end of the diverter joint is provided with a main connection port connected to the end of the main pipe, and the other end of the diverter joint is provided with two or more diverter pipes facing the same direction side by side. The end of the diverter pipe is provided with a diverter interface. The dust collection hood is provided with two or more, and the inner end of each dust collection hood is connected to the corresponding diverter interface. The disadvantage of this patent is that the structure is fixedly installed at the dust-generating point and can only remove dust in a fixed position, but cannot clean dust that has drifted onto the surface of the equipment or the platform. Utility Model Content

The dust suction port 1 includes a dust suction port connection portion connected to the dust suction valve 3. One end of the flexible dust suction pipe 2 is connected to the dust suction valve 3, and the other end is connected to the dust suction system installed on the crusher. The specific structure of the dust suction system installed on the crusher is conventional.

[0025] The dust suction valve 3 includes a valve body 11. There are three openings on the valve body 11, two of which are in opposite directions, and are respectively installed with a dust suction port connector 4 and a dust suction pipe connector 5. A valve body 11 channel is formed between the dust suction port connector 4 and the dust suction pipe connector 5. The other opening is a valve stem 12 mounting port, which is perpendicular to the directions of the other two openings. A valve stem 12 is installed in the valve stem 12 mounting port. A valve core 13 that is adapted to the size of the valve body 11 channel is connected to the valve. The shape of the valve core 13 is approximately disc-shaped. When the surface of the valve core 13 is perpendicular to the direction of the valve body 11 channel, the dust suction valve 3 is in a closed state. When the valve core 13 rotates 90°, the surface of the valve core 13 is parallel to the direction of the valve body 11 channel, and the dust suction valve 3 is in an open state. The valve stem 12 is also connected to a handle 14 located outside the valve body 11. By rotating the handle 14, the rotation of the valve core 13 can be controlled, and the opening and closing of the dust suction valve 3 can be controlled. By controlling the rotation amplitude of the handle 14, the rotation angle of the valve core 13 can be specifically controlled, and the degree of opening of the dust suction valve 3 can be controlled, thereby controlling the intensity of dust suction.
