The mounting frame 12 also includes a staircase 15, and the staircase 15 is fixedly connected to the side of the mounting frame 12, so that people can walk to the mounting frame 12 through the staircase 15 to remove the removed liner, and it is also convenient for people to carry the new liner to the support rod 14, so that the movement of the support rod 14 can transport the new liner to the interior of the ball mill body 1, which is convenient for replacing and installing the liner.

[0031] like Figure 4 and Figure 5As shown, the mounting frame 12 also includes a guide rod 16, a support seat 17, a connecting rod 171 and a return spring 18. The two guide rods 16 are slidably connected to the mounting frame 12. When the sliding block 13 moves, it will contact the left end of the guide rod 16 to push the guide rod 16 to the right into the ball mill body 1. There are three support seats 17. The support seat 17 on the far right is fixedly connected to the right end of the guide rod 16, and the remaining support seats 17 are slidably connected to the guide rod 16. The top surface of the support seat 17 is in sliding contact with the bottom surface of the support rod 14, so as to support the right side of the bottom of the support rod 14 and prevent the support rod 14 from breaking due to the gravity of the liner. The top surface of the support seat 17 is provided with a groove, and the bottom surface of the support rod 14 is provided with a protrusion adapted to the groove on the top surface of the support seat 17, so that the support seat 17 can slide relative to the support rod 14. When the connecting rod 171 moves to contact the rightmost support seat 17, it can push the rightmost support seat 17 and the guide rod 16 to move to the outside of the ball mill body 1.

[0032] Initially, the three support seats 17 are all located outside the ball mill body 1, and the three support seats 17 are in contact with each other and are in a retracted state, and the return spring 18 is in a compressed state; when it is necessary to replace the liner inside the ball mill body 1, first control the cylinder of the ball mill body 1 to rotate to a suitable position so that the bolts on a row of liner plates are aligned with the electric wrench 4, and then control the door panel of the ball mill body 1 to open, and then drive the sliding block 13 to move to the right through the driving assembly, driving the support rod 14 to move to the right into the ball mill body 1, and the support rod 14 can drive the connecting rod 171 to move to the right and separate from the rightmost support seat 17, and then the sliding block 1 3 will contact the left end of the guide rod 16 and push the guide rod 16 to move to the right, driving the support seat 17 to move to the right, so that the leftmost support seat 17 is separated from the mounting bracket 12. At this time, the return spring 18 can return to its original state, driving the support seat 17 to slide and expand on the guide rod 16, so as to support the right side of the bottom of the support rod 14 and ensure the stability of the support rod 14; then the lifting plate 7 is driven down by the electric push rod 16, and the lifting plate 7 can drive the electric wrench 4 to descend through the connecting spring 8. If the nut angle on the lining bolt is just aligned with the output end of the electric wrench 4, the output end of the electric wrench 4 can directly clamp the liner bolt. The nut, if the nut angle on the lining bolt is not aligned with the output end of the electric wrench 4, the output end of the electric wrench 4 will be against the top surface of the nut, the corresponding connecting spring 8 will be compressed, and then the output end of the electric wrench 4 will be controlled to rotate. When the output end of the electric wrench 4 rotates and is aligned with the nut angle on the lining bolt, the corresponding connecting spring 8 will return to its original state, driving the electric wrench 4 to move downward, so that the output end of the electric wrench 4 can clamp the nut on the lining bolt, and then the output end of the electric wrench 4 can drive the nut to rotate, and at the same time, the electric push rod 6 can be controlled to drive the lifting plate 7 to rise, and the lifting plate 7 can be driven by the connecting spring 8 The electric wrench 4 rises, thereby separating the nut from the bolt on the liner, and the magnet 5 can attract the nut, so that the nut is temporarily stored in the output end of the electric wrench 4. Then, the air hammer 10 drives the knocking rod 11 to reciprocate up and down, and the knocking rod 11 can reciprocate and knock the bolt on the liner, so that a row of liner falls down and separates from the cylinder of the ball mill body 1. The support rod 14 can catch the falling liner; then, the driving assembly drives the sliding block 13 to move to the left and reset, which can drive the support rod 14 to move to the left to the outside of the ball mill body 1. The support rod 14 can drive the removed liner to move to the left to the outside of the ball mill body 1;At the same time, the support rod 14 can drive the connecting rod 171 to move to the left. When the connecting rod 171 contacts the rightmost support seat 17, it can push the support seat 17 and the guide rod 16 to move to the left to the outside of the ball mill body 1. When the leftmost support seat 17 contacts the mounting bracket 12, the mounting bracket 12 can squeeze the support seat 17 to slide and retract on the guide rod 16, and the reset spring 18 is compressed. Then people can walk to the top surface of the mounting bracket 12 through the stairs 15, and then manually remove the liner on the support rod 14. Then, the new liner can be placed side by side between the two support rods 14. Repeating the above operation, the new liner can be transported into the ball mill body 1 via the support rod 14. Then, the electric push rod 20 drives the push rod 19 upward, which can lift the liner on the support rod 14, allowing the bolts on the liner to pass through the barrel of the ball mill body 1. The electric wrench 4 is then controlled to descend, and the nut can be driven by the magnet 5 to descend and fit onto the liner bolt. At the same time, the nut is reversed through the output end of the electric wrench 4, and the new liner can be installed on the barrel of the ball mill body 1. This reciprocating process can automatically complete the liner replacement work of the ball mill body 1.

When the push plate 21 moves to the left, it can push the lining on the support rod 14. The blocking roller 23 can guide the lining so that the lining falls accurately into the collection frame 22 for collection; when the lining on the support rod 14 needs to be removed, the push plate 21 can be driven to the left by the moving component. The push plate 21 can push the lining on the support rod 14 to move to the left, so that the lining falls onto the blocking roller 23. At this time, the blocking roller 23 can protect the driving component to prevent the driving component from being damaged by the lining, and the blocking roller 23 can guide the lining so that the lining can accurately fall into the collection frame 22, which is convenient for subsequent unified processing.

[0034] like Figure 7 and Figure 8As shown, it also includes a connecting seat 24 and a roller 25. The top surface of the bottom plate is fixedly connected to the connecting seat 24, and the connecting seat 24 is located below the cylinder of the ball mill body 1.
