[0040] Specifically, during the feeding operation of the crusher, it is first necessary to start the feeding conveyor belt device 10, and then place the material on the conveyor belt of the feeding conveyor belt device 10; the material is smoothly fed into the hollow box 17 through the transmission mechanism of the feeding conveyor belt device 10; in the process of the material entering the hollow box 17, the bearing plate 24 plays a role of receiving; at this time, the metal spring 14 will generate a downward pressure due to the weight of the material, and at the same time drive the hollow box 17 and the pressing block 18 to descend synchronously; when the hollow box 17 descends to the lowest position, the pressing block 18 will press the control button 13; after the control button 13 is pressed, the drive motor 22 will be started by electrical connection, and the feeding conveyor belt device 10 will be closed at the same time; a pressure sensor is installed inside the control button 13, which can sense the pressing force, thereby realizing the function of pressing to open and close; after the drive motor 22 is started, the drive gear 23 starts to rotate; the rotation of the gear 23 is meshed with the sawtooth bar 21, so that the sawtooth bar 21 slides on the slide rail 11; the sliding trajectory is precisely planned to ensure that the sawtooth bar 21 and the push rod 19 The moving trajectory of the hollow box 17 is consistent; the push rod 19 is engaged with the arc groove 20 during the movement, thereby pushing the hollow box 17 to move along the predetermined trajectory; during the movement of the hollow box 17, the slide bar 15 slides in the slide groove 16, further ensuring the accuracy of the moving trajectory of the hollow box 17; when the hollow box 17 moves beyond the range of the carrying plate 24, the material will leak out of the hollow box 17 and slide along the inclined plate 9 into the crusher for crushing; after the material is poured out, the driving motor 22 will drive the gear 23 to rotate in the opposite direction, so that the push rod 19 It generates a strong magnetic adsorption effect with the neodymium magnet material inside the arc groove 20, pulling the hollow box 17 to reset synchronously; after the reset is completed, the push rod 19 leaves the range of the arc groove 20, and the metal spring 14 loses resistance, driving the hollow box 17 to rise, and the supporting plate 24 also rises synchronously; at this time, the control button 13 loses the pressing weight, the drive motor 22 is turned off, and the feeding conveyor belt equipment 10 is restarted to continue the material transmission work; the entire feeding process does not require manual intervention, and the weight floating deviation of a single feeding is small, ensuring the efficient and stable operation of the crusher.

[0041] Reference Figure 1 , Figure 4 and Figure 5, the protective mechanism 2 includes a hollow box 201. The hollow box 201 is arranged on the left side of the bracket 1. A feeding hole 202 is opened at the bottom of the hollow box 201. A fixing rod 203 is fixedly connected to the inner side of the feeding hole 202. Torsion springs 204 are arranged at both the front and rear ends of the outer wall of the fixing rod 203. The mutually remote ends of the torsion springs 204 are respectively fixedly connected to the front and rear sides of the inner wall of the feeding hole 202. A rotating plate 205 is rotatably connected to the middle of the fixing rod 203. The adjacent ends of the torsion springs 204 are respectively fixedly connected to the middle of the front and rear sides of the rotating plate 205. A plurality of buckles 206 are fixedly connected to the bottom of the left rotating plate 205 at equal intervals. A plurality of clamping grooves 207 are opened at the top of the right rotating plate 205 at equal intervals. The plurality of buckles 206 are respectively engaged with the corresponding clamping grooves 207. A servo motor 4 is fixedly connected to the outside of the hollow box 201. The output end of the servo motor 4 penetrates through the hollow box 201 and is fixedly connected to a crushing blade 6. A feeding conveyor device 10 is installed at the top of the bracket 1. A discharging conveyor device 5 is arranged at the bottom of the hollow box 201.

[0042] Specifically, after the materials are placed into the feeding port of the crusher, these materials will naturally fall on the rotating plate 205. Due to the weight of the materials, the rotating plate 205 will drive the torsion springs 204 to store energy and flip. This flipping action enables the materials to smoothly fall into the hollow box 201. At the same time, the servo motor 4 starts to operate, driving the crushing blade 6 to rotate at a high speed to effectively crush the materials. After the feeding work is completed, the potential energy of the torsion springs 204 will rebound, prompting the rotating plate 205 to return to its original position. During this process, the buckles 206 will automatically insert into the clamping grooves 207 for firm engagement, thereby closing the feeding hole 202. This design effectively prevents the scattering of crushed stones and the diffusion of crushing smoke that may occur during the crushing process, greatly reducing the safety hazards and ensuring the safety of the operators. The crushed materials are discharged through the discharging conveyor device 5.

[0043] Refer to Figure 1 , fixing frames 8 are fixedly connected to both the front and rear sides of the bottom of the hollow box 201. A stabilizing rod 7 is fixedly connected to the inner side of the fixing frame 8.

[0044] Specifically, through the cooperation of the fixing frame 8 and the stabilizing rod 7, the stability of the equipment during support is increased.

[0045] Working principle: When feeding the crusher, turn on the feeding conveyor belt device 10 and place the material on the feeding conveyor belt device 10. The material is conveyed by the feeding conveyor belt device 10 and sent into the hollow box 17, which is received by the bearing plate 24. When receiving, the metal spring 14 is pressed down by the weight, and at the same time, the hollow box 17 and the pressing block 18 are synchronously lowered. After descending to the bottom, the pressing block 18 presses the control button 13. By pressing the control button 13, the drive motor 22 is turned on and the feeding conveyor belt device 10 is turned off. The control button 13 is electrically connected to the drive motor 22 and the feeding conveyor belt device 10, and a pressure sensor is installed in the control button 13 to achieve the effect of pressing to turn on and off. After the drive motor 22 is turned on, the drive gear 23 rotates. The rotation of the gear 23 meshes with the saw tooth rack 21 for transmission, so as to drive the saw tooth rack 21 to slide on the slide rail 11, planning the moving trajectories of the saw tooth rack 21 and the push rod 19. The movement of the push rod 19 is fitted with the arc groove 20, so as to push the hollow box 17 to move. When the hollow box 17 moves, it drives the slide bar 15 to slide in the chute 16, planning the moving trajectory of the hollow box 17. When the hollow box 17 moves out of the range of the bearing plate 24, the material leaks out of the hollow box 17 and slides into the crusher through the inclined plate 9 for crushing. After the material is poured out, the drive motor 22 drives the gear 23 to rotate in the reverse direction, and both the inside of the push rod 19 and the arc groove 20 are made of neodymium magnet material. The strong magnetic adsorption pulls the hollow box 17 to be reset synchronously. After resetting, the push rod 19 leaves the range of the arc groove 20. At the same time, the metal spring 14 loses the resistance and drives the hollow box 17 to rise, and the bearing plate 24 rises synchronously, so that the control button 13 loses the pressing weight, synchronously turning off the drive motor 22 and turning on the feeding conveyor belt device 10 to continue the material transmission work;

[0046] And after the crusher is fed, the material falls on the rotating plate 205. The rotating plate 205 is driven by the weight to store energy and flip the torsion spring 204, so that the material falls into the hollow box 201. At the same time, the servo motor 4 is turned on to drive the crushing blades 6 to rotate for crushing the material. When the feeding work ends, the potential energy of the torsion spring 204 rebounds to drive the rotating plate 205 to reset, and at the same time, the buckle 206 is inserted into the card slot 207 for clamping, so as to close the feeding hole 202.

[0047] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features.
