Description

Technical Field

[0001] This utility model relates to the field of open-pit mine crushing technology, and in particular to an adjustable crushing mechanical device for an open-pit mine control platform. Background Technology

[0002] Mineral resource mining refers to the mining of solid metal and non-metal deposits, including open-pit mining of surface ore bodies and shallow ore bodies, as well as underground mining of blind mines and deep ore bodies. Crushing equipment is required during ore mining to refine and crush the ore.

[0003] The existing crushing machinery in open-pit mine management platforms mostly lacks adjustable spacing between crushing rollers. Because the roller spacing is not adjustable, the crusher may not be able to adapt to different material characteristics and crushing requirements, resulting in insufficient or excessive crushing and reducing overall production efficiency.

[0004] Therefore, for the crushing machinery of open-pit mine management platforms, the spacing between most crushing rollers cannot be adjusted. Because the spacing between the crushing rollers cannot be adjusted, the crusher may not be able to adapt to different material characteristics and crushing requirements, resulting in insufficient or excessive crushing and reduced overall production efficiency. Adjustable crushing machinery for open-pit mine management platforms can be designed. By flexibly adjusting the spacing between the crushing rollers, it can crush different minerals, thereby solving the problem that the spacing between most crushing rollers cannot be adjusted, which prevents the crusher from adapting to different material characteristics and crushing requirements, resulting in insufficient or excessive crushing and reduced overall production efficiency. Utility Model Content

[0013] The beneficial effects of this utility model are as follows: Compared with the traditional crushing machinery devices of open-pit mine control platforms, most crushing rollers cannot be adjusted in terms of spacing.

A threaded rod 319 is provided at the output end of the third motor 318. A fourth fixing plate 320 is provided on the outer side of the threaded rod 319. The fourth fixing plate 320 is connected to the crushing box 2. A fixed connection is established, with a movable block 321 threadedly connected to the outer side of the threaded rod 319. The movable block 321 is rotatably connected to the second crushing roller 312. A second slider 322 is provided on the outer side of the second crushing roller 312. A groove is provided at the corresponding position of the crushing box 2 and the first crushing roller 306. The first crushing roller 306 is rotatably connected inside the groove of the crushing box 2. The groove at the corresponding position of the crushing box 2 and the first crushing roller 306 provides a limiting effect when the first crushing roller 306 rotates inside the groove. A groove is also provided at the corresponding position of the crushing box 2 and the second crushing roller 312. The second crushing roller 312 is slidably connected inside the groove of the crushing box 2. The groove at the corresponding position of the crushing box 2 and the second crushing roller 312 provides a limiting effect when the second crushing roller 312 rotates inside the groove. The grooves on the inner side of the slots act as a limiting mechanism. Grooves are provided at corresponding positions of the crushing box 2 and the first slider 316. The first slider 316 is slidably connected inside the groove of the crushing box 2. The grooves on the crushing box 2 and the first slider 316 act as a limiting mechanism when sliding inside the groove. Similarly, grooves are provided at corresponding positions of the crushing box 2 and the second slider 322. The second slider 322 is slidably connected inside the groove of the crushing box 2. The grooves on the crushing box 2 and the second slider 322 act as a limiting mechanism when sliding inside the groove. By activating the third motor 318, the threaded rod 319 rotates, which in turn moves the movable block 321.The movable block 321 drives the second crushing roller 312 to move, and the second crushing roller 312 drives the second slider 322 to slide, thereby adjusting the distance between the second crushing roller 312 and the first crushing roller 306. The spring 315 drives the first slider 316 to slide, and the first slider 316 drives the tension wheel 317 to move, keeping the second transmission belt 310 taut. The damper 314 mainly reduces vibration and impact, making the rotation of the second crushing roller 312 more stable. By starting the first motor 302, the first motor 302 drives the first pulley 303 to rotate, and the first pulley 303 drives the first transmission belt... When belt 304 rotates, the first transmission belt 304 drives the second pulley 305 to rotate, which in turn drives the first crushing roller 306 to rotate clockwise. This starts the second motor 308, which drives the third pulley 309 to rotate. The third pulley 309 then drives the second transmission belt 310 to rotate, which in turn drives the fourth pulley 311 to rotate. The fourth pulley 311 then drives the second crushing roller 312 to rotate counterclockwise. The ore is then added to the crushing box 2, where it is crushed through the interaction of the first crushing roller 306 and the second crushing roller 312.

[0022] During operation, the third motor 318 is activated, driving the threaded rod 319 to rotate. The threaded rod 319 then moves the movable block 321, which in turn moves the second crushing roller 312. The second crushing roller 312 then moves the second slider 322, thereby adjusting the distance between the second crushing roller 312 and the first crushing roller 306. The spring 315 drives the first slider 316 to slide, which in turn moves the tension wheel 317, keeping the second transmission belt 310 taut. The damper 314 primarily reduces vibration and impact, making the rotation of the second crushing roller 312 more stable. The first motor 302 is activated, driving the first pulley 303 to rotate. The first pulley 303 then drives the first transmission belt 304 to rotate, which in turn drives the second pulley. When the second pulley 305 rotates, it drives the first crushing roller 306 to rotate clockwise, thus starting the second motor 308. The second motor 308 drives the third pulley 309 to rotate, which in turn drives the second transmission belt 310 to rotate. The second transmission belt 310 drives the fourth pulley 311 to rotate, which in turn drives the second crushing roller 312 to rotate counterclockwise. Then, the ore is added to the crushing box 2, where it is crushed by the cooperation of the first crushing roller 306 and the second crushing roller 312. The fourth motor 401 is then started, driving the first transmission roller 402 to rotate. The first transmission roller 402 drives the conveyor belt 403 to rotate, which in turn drives the second transmission roller 404 to rotate.
