[0027] The ball mill main body 100 comprises a support platform 101, a fixed plate 102 arranged directly below the support platform 101, and a surface feeding type ball mill 103 adaptively installed on the top of the fixed plate 102.

[0028] It should be explained that the support platform 101 and the fixed plate 102 are used to provide basic support for the ball mill body 100, and the surface feeding type ball mill 103 is provided with an openable feeding port.

[0029] The moving mechanism 200 comprises a feeding port 201 provided on the top of the support platform 101 and matched with the surface feeding type ball mill 103, guide rails 202 fixedly connected to the two side surfaces of the support platform 101 respectively, a sliding trolley 203 slidingly connected to the outer surfaces of the guide rails 202, a hopper 204 fixedly installed on the top of the sliding trolley 203, limiting rods 205 fixedly connected to the two ends of the guide rails 202 respectively and matched with the sliding trolley 203 to prevent the sliding trolley 203 from derailing, a splicing assembly 206 matched with the hopper 204, and a positioning assembly 207.

[0030] It should be explained that the feeding port 201 is located directly above the feeding port of the surface feeding type ball mill 103, and the material enters the inside of the surface feeding type ball mill 103 through the feeding port 201, the guide rails 202 are used to guide the movement of the sliding trolley 203, and when the sliding trolley 203 slides along the guide rails 202, the sliding trolley 203 can drive the load-bearing hopper 204 to move synchronously, the hopper 204 is used to receive the material, and the limiting rods 205 are used to prevent the sliding trolley 203 from derailing.

[0031] Specifically, the two guide rails 202 are located on the two sides of the feeding port 201 respectively, and the inner cavities of the sliding trolley 203 and the hopper 204 are communicated.

[0032] Further, the splicing assembly 206 comprises connecting columns 206a fixedly connected to the two side surfaces of the hopper 204 respectively, a fixed rod 206b fixedly connected to the other end of the connecting column 206a, a fixed block 206c fixedly installed on the outer end surface of the fixed rod 206b, and a sliding block 206d slidingly sleeved on the outer surface of the fixed rod 206b.

[0033] It should be further explained that when the sliding block 206d moves to a position in contact with the fixed block 206c, the sliding block 206d and the fixed block 206c can form an integral whole.

[0034] Preferably, the fixed rod 206b and the fixed block 206c are of the same shape, and one side of the fixed rod 206b and the fixed block 206c is a plane and the other side is an inclined surface.

[0035] It should be explained that the positioning assembly 207 comprises support plates 207a fixedly connected to the two side surfaces of the support platform 101 respectively, sleeves 207b fixedly installed on the outer surfaces of the support plates 207a and matched with the connecting columns 206a, and limiting grooves 207c provided on the inner walls of the two sides of the sleeves 207b respectively.

[0036] Further, the positioning assembly 207 further comprises a spring 207d fixedly installed on the inner wall of the limiting groove 207c, and a limiting block 207e fixedly connected to the other end of the spring 207d.

[0037] Wherein, through the limiting of the limiting block 207e by the limiting groove 207c, the limiting block 207e can only move linearly when being extruded by external force.

[0038] Specifically, the outer surface of the limiting block 207e is in sliding contact with the inner wall of the limiting groove 207c, one side of the limiting groove 207c close to the outlet of the sleeve 207b is a slope and the other side is a plane.

[0039] In use, the control hopper 204 is moved along the guide rail 202 until reaching a predetermined maximum stroke position, in the process, the hopper 204 drives the connecting column 206a, the fixed rod 206b, the fixed block 206c and the sliding block 206d to move synchronously to the inner cavity of the sleeve 207b, the fixed block 206c extrudes the slope of the limiting block 207e, the limiting block 207e is extruded into the limiting groove 207c, and the spring 207d is given a pressure, when the plane part of the fixed block 206c continues to move and is in contact with the plane of the limiting block 207e, the limiting block 207e is reset by the reaction force of the spring 207d, the limiting block 207e limits the fixed block 206c, and then the fixed block 206c limits the connecting column 206a and the hopper 204 through the fixed rod 206b to ensure that the position of the hopper 204 remains stable, so as to automatically lock the hopper 204 when it moves to the maximum stroke to avoid the effect of rebound;

[0040] When the limiting of the hopper 204 needs to be released: the hopper 204 is continuously controlled to move along the guide rail 202, the sliding block 206d extrudes the limiting block 207e through the connecting column 206a, the limiting block 207e is extruded into the limiting groove 207c again, and the spring 207d is given a pressure, when the slope part of the sliding block 206d continues to move and is in contact with the end of the limiting block 207e, the limiting block 207e is pushed out by the reaction force of the spring 207d, the limiting block 207e clamps the sliding block 206d, at this time, the connecting column 206a moves outside the sleeve 207a, the fixed block 206c is driven to move to the position in contact with the sliding block 206d through the connecting column 206a and the fixed rod 206b, the fixed block 206c and the sliding block 206d form an integral whole, and the limiting block 207e is extruded by the sliding block 206d at the same time, and the fixed block 206c smoothly passes through the limiting block 207e.

[0041] In summary, through the cooperation of various components in the splicing assembly 206 and the positioning assembly 207, the hopper 204 can be automatically locked when it moves to the maximum stroke, effectively avoiding the problem of position deviation of the hopper 204 due to the rebound force, ensuring the stability of the position of the hopper, and when the hopper 204 needs to be repositioned, only by pushing the hopper 204 can the locked state be released, so as to realize the effect of maintaining the stability of the hopper 204 in the production process while facilitating the maintenance and adjustment of the hopper 204.
