The connection relationship between the two gears 201 is meshing connection.

[0021] In this implementation scheme, by setting the crushing roller 2, the gear 201 and the motor 202, by starting the motor 202 to drive one of the gears 201 to rotate through its output shaft, and using the meshing connection relationship between the gears 201, the other gear 201 can be driven to rotate, and then the two crushing rollers 2 can be driven to rotate. The staff puts the rocks into the screening box 1 through the feeding port 101, and then the crushing treatment of the rocks can be carried out, which is convenient for the subsequent detection of trace elements of the rocks.

[0022] Specifically, sliders 301 are fixedly provided on both sides of the filter plate 3, and slide grooves 302 adapted to the sliders 301 are fixedly provided on both sides of the inner wall of the screening box 1, and the connection relationship between the sliders 301 and the slide grooves 302 is a sliding connection.

[0023] In the present embodiment, by setting a slider 301 and a slide groove 302, utilizing the sliding connection relationship between the slider 301 and the slide groove 302, when a lot of rocks are accumulated on the top of the filter plate 3 and the filtering effect is affected, the filter plate 3 can be taken out from the inside of the screening box 1 by pulling the filter plate 3 outward, thereby realizing the disassembly of the filter plate 3, facilitating the cleaning of the filter plate 3, having strong practicality, and being convenient for users to use.

[0024] Specifically, a material guide plate 4 is fixedly disposed inside the screening box 1 and below the filter plate 3 , and a material outlet 5 is opened on the screening box 1 on one side of the material guide plate 4 .

[0028] Specifically, the connection relationship between the threaded rod 702 and the nut seat 704 is a threaded connection, and a threaded hole matched with the threaded rod 702 is opened inside the nut seat 704.

[0029] In the present embodiment, by setting a threaded rod 702 and a nut seat 704, utilizing the threaded connection relationship between the threaded rod 702 and the nut seat 704, the threaded rod 702 is driven to rotate by rotating the rotating handle 703, so that the nut seat 704 makes a vertical lifting movement along the outside of the threaded rod 702, and then the nut seat 704 drives the cleaning brush 705 to make a vertical lifting movement, so that the filter screen 701 can be cleaned, the mesh of the filter screen 701 can be prevented from being blocked, and the mesh can be kept unobstructed. It has strong practicality and is convenient for users to use.

[0030] In use, the staff first put the rock into the interior of the screening box 1. By starting the motor 202, its output shaft drives one of the gears 201 to rotate. Utilizing the meshing connection relationship between the gears 201, it can drive the other gear 201 to rotate, and further drive the two crushing rollers 2 to rotate. The staff put the rock into the interior of the screening box 1 through the feed port 101, and then the crushing process of the rock can be carried out. The dust generated during the crushing process is made to enter the interior of the filter box 7 through the dust suction pipe 706 by starting the exhaust fan 6. The filter screen 701 can block the dust to prevent the dust from entering the interior of the exhaust fan 6 and damaging the internal parts of the exhaust fan 6. When the mesh holes of the filter screen 701 are blocked by dust, by rotating the rotating handle 703 to drive the threaded rod 702 to rotate, the nut seat 704 drives the cleaning brush 705 to move vertically up and down along the outside of the threaded rod 702, and then the cleaning of the filter screen 701 can be carried out to keep the mesh holes of the filter screen 701 unobstructed. After crushing, the rock falls onto the top of the guide plate 4 after being filtered by the filter plate 3, and then is discharged through the discharge port 5, completing the processing work before the trace element test of the rock.
