This method can effectively transmit the power of the motor 2 and ensure the efficient operation of the crusher. A reducer 4 is fixedly mounted on the top surface of the frame 1, and the reducer 4 is connected to the frame 1 through a flange. The flange connection has high strength and stability, which can ensure the smooth operation of the reducer 4 during operation. A driven pulley 5 is mounted on the input end of the reducer 4, and the driven pulley 5 is connected to the driving pulley 3 by a belt. The belt is made of high-strength rubber material with wear resistance and tensile strength, ensuring stability and reliability during long-term operation. The output end of the reducer 4 is mounted on a drive shaft 6. A crushing wheel 7 is fixedly mounted on one end of the drive shaft 6. This crushing wheel 7 is secured to the drive shaft 6 via a keyed connection, ensuring no slippage during transmission and ensuring efficient crushing. A crushing box 17 is fixedly mounted on the top surface of the frame 1. This mounting arrangement ensures stability and facilitates disassembly and cleaning. The inner wall of the crushing box 17 is defined by side grooves 8, which are slidably connected to a slider 9. The slider 9 can be connected using guide rails or bearings to ensure smooth and precise movement. A mounting block 10 is fixedly mounted on one end of the slider 9. The mounting block 10 can be bolted to the slider 9, making this connection convenient for assembly and disassembly of the slider 9 and mounting block 10. A rotating rod 11 is rotatably connected to the inner side of the mounting block 10. The rotating rod 11 is mounted on the mounting block 10 via a bearing. This bearing connection provides low-friction, high-precision rotational motion, ensuring flexible rotation of the rotating rod 11. A cover plate 12 is fixedly mounted on the surface of the rotating rod 11. The material of the cover plate 12 can be selected from high-strength alloy steel or wear-resistant cast iron to ensure its durability and impact resistance during long-term use. A torsion spring 13 is sleeved on the surface of the cover plate 12. One end of the torsion spring 13 is fixedly connected to the mounting block 10, and the other end is fixedly connected to the cover plate 12. The torsion spring 13 can be made of spring steel material, which has good elasticity and durability and can maintain stable torque for a long time. A limit plate 14 is fixedly mounted on the top surface of the mounting block 10. The limit plate 14 is fixed to the mounting block 10 by welding. The welded connection can provide higher strength and stability, ensuring that the cover plate 12 can accurately resist the limit plate 14 when resetting. The motion interference design between the cover plate 12 and the limit plate 14 effectively prevents stone from splashing out during the crushing process, protecting the safety of the operator.

[0027] See also Figure 1-6A connecting frame 15 is fixedly mounted on the top surface of the mounting block 10.

The hydraulic cylinder 16 is fixed to the back of the frame 1 by bolts or flanges to ensure that it can stably drive the connecting frame 15 up and down. When the hydraulic cylinder 16 pushes the connecting frame 15, it can drive the mounting block 10 and the cover plate 12 to move downward, thereby compacting the stone in the crushing box 17, ensuring that the stone can be in closer contact with the crushing wheel 7, and improving the crushing efficiency. Especially when processing large quantities of ore, this design ensures the efficient operation of the equipment.

[0028] Example 2

[0029] See also Figure 4-6 The top surface of the cover plate 12 is provided with a protective mechanism, which includes a protective plate 18. The protective plate 18 is made of high manganese steel and has high wear resistance and impact resistance, which can effectively protect the cover plate 12 from damage when stones are put into it. The protective plate 18 is installed on the top surface of the cover plate 12 and is fixed by the cooperation of the plug column 21 and the top groove 19. The plug column 21 can be fixed to the protective plate 18 by means of threaded connection or snap connection, ensuring that the protective plate 18 is firmly installed and easy to disassemble. The inner wall of the top groove 19 is fixed with a magnet 20, which is installed on the inner wall of the top groove 19 by gluing or embedding. Such a design can effectively utilize the magnetic force of the magnet 20 to adsorb the plug column 21, thereby fixing the protective plate 18. The post 21 is the same size as the top groove 19. The post 21 is made of ferritic stainless steel, which has good corrosion resistance and magnetic matching properties, and can ensure easy operation when installing and removing the protective plate 18. At the same time, a one-millimeter gap is left between the magnet 20 and the post 21 to prevent the post 21 from directly hitting the magnet 20 and causing damage.

[0030] Working principle: The motor 2 drives the active pulley 3 to rotate, and the active pulley 3 can then drive the driven pulley 5 to rotate through the belt, and then drive the active shaft 6 to rotate through the reducer 4, and the active shaft 6 can then drive the crushing wheel 7 to rotate, and the crushing wheel 7 can then crush the mineral stone in the crushing box 17. At the same time, when putting in the mineral stone, it is only necessary to put the mineral stone from the top of the crushing box 17, and then the mineral stone can be squeezed downward due to the action of gravity to open the cover 12, and then fall onto the crushing wheel 7 to be crushed. After the cover 12 loses the squeezing of the stone, due to the torsion of the torsion spring 13, the torsion spring 13 can drive the cover 12 to rotate, and the cover 12 is rotated by the rotating rod 11 at this time until the top of the cover 12 hits the limit. The cover plate 12 is reset at this time, and the crushing box 17 can be covered at this time, so that the stones can be prevented from splashing out and injuring people during crushing. At the same time, the hydraulic cylinder 16 can also drive the connecting frame 15 to move downward, and the connecting frame 15 can then drive the mounting block 10 to move downward, and the mounting block 10 can then drive the cover plate 12 to move downward. The cover plate 12 can then squeeze the internal stones downward, which can improve the crushing efficiency of the stones. Especially when there are many stones, the normal crushing of the stones can be guaranteed by squeezing downward. The utility model avoids the safety hazards caused by the splashing of stones during the crushing process by designing the cooperation between the cover plate 12 and the limit plate 14, thereby protecting the safety of the operators. At the same time, after the cover plate 12 loses the squeezing of the stones, it relies on the torsion spring 1 3 is automatically reset to ensure that the crushing box 17 is always in a closed state during the crushing process, effectively preventing stones from splashing out, reducing the complexity of operation, and improving the degree of automation of the equipment. The hydraulic cylinder 16 drives the linkage movement of the connecting frame 15, the mounting block 10, and the cover plate 12, which can squeeze it downward when there are more stones, so that the stones are more closely in contact with the crushing wheel 7, thereby improving the crushing efficiency. It is particularly suitable for processing large quantities of ores and ensuring the efficient operation of the equipment. The protective plate 18 can protect the cover plate 12. When stones are put in, the protective plate 18 can withstand the impact and scratches of the stones. At the same time, after the protective plate 18 is damaged, the staff only needs to pull the protective plate 18 upwards, and the protective plate 18 can then be brought When the movable plug post 21 leaves the top groove 19, the protective plate 18 can be removed. When installing the protective plate 18, it is only necessary to align the plug post 21 under the protective plate 18 with the top groove 19 and insert it until the plug post 21 is against the magnet 20. At this time, due to the magnetic force of the magnet 20, the ferritic stainless steel plug post 21 can be attracted. At this time, the protective plate 18 can be installed. After the protective plate 18 is installed, a one-millimeter gap can be left between the magnet 20 and the plug post 21. This can prevent the plug post 21 from impacting the magnet 20 and causing the magnet 20 to break. The utility model protects the cover plate 12 by arranging the protective plate 18. The protective plate 18 withstands the impact and scratching of the stone, avoiding direct damage to the cover plate 12, thereby extending the service life of the cover plate 12 and the entire equipment.The protective plate 18 is designed with a plug-in post 21 and a top slot 19, and is fixed with a magnet 20. The staff only needs to pull and insert the protective plate 18 to complete the replacement. The operation is convenient, the maintenance cost is low, the downtime is reduced, and the operation efficiency of the equipment is improved.
