At the same time, the connecting pipe 6 cooperates with the nozzle 7 to spray water on the ore material guided inside the feeding hopper 3 to reduce the dust generated during the subsequent ore crushing process by the crushing seat 2. At the same time, the nozzle 7 sprays water mist on the dust during the ore crushing process for dust reduction work. The lifting connection mechanism includes a lifting seat 8, a lifting rod 9 and a lifting block 10. The lifting seat 8 is fixedly connected to the inner wall of the protection frame 4. The lifting rod 9 is fixedly connected to the top of the inner wall of the lifting cover 5. The lifting block 10 is fixedly connected to the bottom of the outside of the lifting rod 9. The outside of the lifting block 10 is located inside the lifting seat 8, which can perform lifting connection work between the lifting cover 5 and the protection frame 4, and avoid the situation that the lifting cover 5 is displaced and separated from the protection frame 4 during use. Therefore, the use stability of the lifting cover 5 is improved.

[0033] Referring to Figures 2-4 , in a preferred embodiment, by fixedly connecting a magnetic strip 11 to the inner wall of the lifting seat 8 and inlaying and connecting a magnetic block 12 magnetically connected to the magnetic strip 11 on the outside of the lifting seat 8, the lifting cover 5 and the protection frame 4 can be lifted and magnetically positioned by the cooperation of the lifting block 10, the lifting column and the lifting rod 9. Therefore, the lifting positioning convenience of the lifting cover 5 is improved. A tightening seat 13 is fixedly connected to the bottom of the rear side of the lifting cover 5. A tightening disc 14 is movably connected to the inside of the tightening seat 13, which can perform tightening and positioning stability work between the lifting cover 5 and the protection frame 4, and ensure the positioning stability and convenience between the lifting cover 5 and the protection frame 4.

[0034] Referring to Figures 2-4, in a preferred embodiment, a screw cylinder 15 is fixedly connected to the rear side of the pressing seat 13, and a screw handle 16 is threadedly connected to the inside of the screw cylinder 15. The front side of the screw handle 16 is fixedly connected to the rear side of the pressing disc 14, which can provide a medium for the user to apply force to press the pressing disc 14, ensuring the convenience and effectiveness of the pressing and positioning of the pressing disc 14. The front side of the top of the lifting cover 5 is movably connected to a rotating rod 17, and the bottom of the rotating rod 17 is fixedly connected to a protective curtain 18 located inside the lifting cover 5, which can perform flexible blocking and protection work on the front side of the protective frame 4 and the lifting cover 5, ensuring the feeding of the front side of the protective frame 4 and the lifting cover 5, and at the same time not affecting the blocking and protection of the crushed stones.

[0035] Referring to Figures 2-5 , in a preferred embodiment, support frames 19 are fixedly connected to both sides of the top of the lifting cover 5, and support shafts 20 penetrating to the outside of the support frames 19 are fixedly connected to both sides of the rotating rod 17, which can perform support and stability work between the rotating rod 17 and the lifting cover 5, ensuring the stability of the rotating rod 17 during operation. A magnetic ring 21 is inlaid on the surface of the support shaft 20, and a magnetic attraction ring 22 magnetically connected to the magnetic ring 21 is inlaid on the inner wall of the support frame 19, which can perform magnetic attraction and positioning work between the rotating rod 17 and the support frame 19 through the support shaft 20, ensuring the convenience of the rotational positioning of the rotating rod 17.

[0036] Specifically, the working process or principle of the feeding device for the mine crusher is as follows: During use, first, according to the actual feeding requirements of the ore in the external mine, hold the lifting cover 5 and move it upward to adjust the feeding space in front of the protective frame 4 and the lifting cover 5. At this time, the lifting block 10 moves inside the lifting seat 8 through the lifting rod 9 following the lifting cover 5 to perform the lifting connection work between the lifting cover 5 and the protective frame 4. At the same time, the magnetic strip 11 cooperates with the magnetic block 12 to perform the magnetic attraction positioning work between the adjusted lifting cover 5 and the protective frame 4 through the lifting block 10. Then, rotate the screw handle 16 to cooperate with the screw cylinder 15 to apply a tightening force to the tightening disc 14, so that the tightening disc 14 contacts and presses against the surface of the protective frame 4 to perform the tightening and positioning and stabilizing work between the protective frame 4 and the lifting cover 5. Then, rotate the rotating rod 17 through the support shaft 20 to perform the winding and unwinding adjustment operation on the protective curtain 18, so that the protective curtain 18 performs the flexible protection work on the front feeding space of the lifted lifting cover 5 and the protective frame 4. At this time, the support shaft 20 cooperates with the support frame 19 to perform the support and stabilizing work between the rotating rod 17 and the lifting cover 5. At the same time, the magnetic ring 21 cooperates with the magnetic attraction ring 22 to perform the magnetic attraction positioning work between the rotating rod 17 and the support seat through the support shaft 20. Subsequently, connect the connecting pipe 6 to the external water source through the connector at the top of the connecting pipe 6 to provide a water spraying source for the nozzle 7. When the external ore enters the inside of the feeding hopper 3 through the opening in front of the protective frame 4 and the lifting cover 5, the protective curtain 18 performs the flexible feeding protection work on the ore during the ore feeding process. During this process, the protective frame 4 cooperates with the lifting frame to block and protect the flying crushed stones during the ore addition and crushing processes. At the same time, the connecting pipe 6 cooperates with the nozzle 7 to spray and moisten the ore material guided inside the feeding hopper 3 to reduce the dust generated during the subsequent crushing of the ore by the crushing seat 2. At the same time, the nozzle 7 sprays water mist to perform the dust reduction work on the dust generated during the ore crushing process.

[0037] It should be noted that the crusher body 1, the crushing seat 2, and the feeding hopper 3 are devices or equipment existing in the prior art, or devices or equipment that can be realized by the prior art. Their power supply, specific composition, and principle are clear to those skilled in the art, so they will not be elaborated in detail.
