The second electric control sliding seat 22 cooperates with the third electric control telescopic column 23 to drive the crushing head to move to the initial position; The second electric control telescopic column 33 drives the brush body to move to a position above the crushing box 14, and then the first electric control sliding seat 32 interacts with the first rail 31 to slide downward, so that the cleaning brush 35 enters the crushing box 14; The first servo motor 36 rotates the cleaning brush 35 at a preset rotation, and the first electric control sliding seat 32 slides upward at a preset speed. The air column is sprayed from the air jet pipe 38 to clean the residues on the surface of the cleaning brush 35, until the cleaning brush 35 completely leaves the crushing box 14, so that the residues of the cleaning brush 35 fall into the storage box.

The cleaning brush is located on the side of the first connecting seat near the crushing chamber, and the first servo motor is located on the side of the first connecting seat away from the cleaning brush. The first servo motor drives and connects to the cleaning brush. The output end of the second electrically controlled telescopic column drives and connects to the first connecting seat. The first servo motor is used to drive the cleaning brush to rotate when the cleaning brush enters the crushing chamber.

6. A rock sample pretreatment device for mineral exploration according to any one of claims 1-3, characterized in that, The crushing mechanism includes a second track, a second electrically controlled slide, a third electrically controlled telescopic column, and a crushing head. The second track is located on the side of the crushing box away from the cleaning mechanism and is vertically arranged. The second electrically controlled slide is slidably connected to the second track. The crushing head is located on the side of the second electrically controlled slide facing the crushing box, and the third electrically controlled telescopic column is located on the side of the second electrically controlled slide facing the crushing head. The output end of the third electrically controlled telescopic column is driven and connected to the crushing head. The third electrically controlled telescopic column is used to drive the crushing head to a position directly above the crushing box. The second electrically controlled slide is used to drive the crushing head into the crushing box through the third electrically controlled telescopic column, so that the crushing head crushes the rock sample inside the crushing box.

7. A rock sample pretreatment device for mineral exploration according to claim 6, characterized in that, The crushing head includes a second connecting seat, a crushing cutter head, a box cover, and a second servo motor. The crushing cutter head is located on the side of the box cover near the crushing box, and the second servo motor is located on the side of the box cover away from the crushing box. The second servo motor drives and connects to the crushing cutter head. The output end of the third electrically controlled telescopic column is driven and connected to the box cover through the second connecting seat. The second servo motor is used to drive the crushing cutter head to rotate when the crushing cutter head enters the crushing box.

8. A rock sample pretreatment device for mineral exploration according to claim 6, characterized in that, The cleaning mechanism also includes a compressed air source, an air jet pipe, and an electrically controlled valve. The compressed air source and the air jet pipe are both located within the accommodating space. The electrically controlled valve is located on the air jet pipe, which is inclined. The output end of the air jet pipe faces the crushing box along its vertical central axis. The air jet pipe is located on one side of the extension path of the third electrically controlled telescopic column, and the feed inlet is located on the other side of the extension path of the third electrically controlled telescopic column.

9. A rock sample pretreatment device for mineral exploration according to claim 8, characterized in that, The cleaning mechanism further includes a blower and a filter bag. The blower is located inside the housing on the side away from the feed inlet and is situated on one side of the compressed air source. The filter bag is located outside the housing and is connected to the blower.
