[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] See also Figures 1 to 3 In an embodiment of the utility model, a feeding safety protection device for ore crushing processing includes a feeding hopper 1, a swing feeding mechanism, a dust suppression mechanism, a rebound protection mechanism and a discharging anti-jamming mechanism.

[0026] The upper surface of the feed hopper 1 is provided with a swinging feeding mechanism, which includes a swinging plate 3, a fixed plate 9 and a swinging shaft 10. The upper end surface of the feed hopper 1 is fixedly connected to two symmetrically distributed fixed plates 9, and the swinging shaft 10 is rotatably connected between the two fixed plates 9. The top end of the swinging shaft 10 is fixedly connected to the swinging plate 3, and baffles are fixedly connected to both ends of the upper surface of the swinging plate 3.

[0027] It should be noted that by swinging the feeding mechanism, it is convenient to lay an inclined guide plate on the upper end of the feed hopper 1, which is convenient for dumping different mine cars. In addition, due to the presence of the baffle, the possibility of debris overflowing from both sides is reduced, the pollution to the surrounding environment is reduced, and the safety performance of the device is improved.

[0028] Dust suppression mechanisms are provided on both sides of the feed hopper 1, and the dust suppression mechanisms include a water inlet pipe 4 and a nozzle 2. The water inlet pipe 4 is fixedly connected to both sides of the feed hopper 1, and the bottom end of the water inlet pipe 4 is connected to an external water source. The top end of the water inlet pipe 4 is fixedly connected to the nozzle 2, and the water outlet end of the nozzle 2 is facing the feed end of the feed hopper 1.

[0029] It should be noted that, through the cooperation between the nozzle 2 and the water inlet pipe 4, water mist can be sprayed while feeding, which greatly reduces dust pollution. In addition, the water mist has a certain lubricating effect, which reduces the possibility of ore falling and getting stuck, and improves the safety of feeding.

[0030] A rebound protection mechanism is provided between the two sides of the top of the feed hopper 1, and the rebound protection mechanism includes a rotating rod 6, a fixed ring 5, a rotating plate 11, a guide plate 15 and a sliding rod 14. The rotating rod 6 is rotatably connected between the inner walls on both sides of the top of the feed hopper 1, and the outer surface of the rotating rod 6 is fixedly connected to two symmetrically distributed fixed rings 5, and the guide plate 15 is fixedly connected to the two fixed rings 5. The two sides of the rotating rod 6 respectively penetrate the inner walls of both sides of the feed hopper 1 and are fixedly connected to the rotating plate 11. Arc grooves 12 are provided on both sides of the feed hopper 1, and the inner end surface of the rotating plate 11 is fixedly connected to the sliding rod 14, and the sliding rod 14 is slidably connected in the arc groove 12, and a spring 13 is connected between the bottom end of the sliding rod 14 and the bottom wall of the arc groove 12.

[0031] It should be noted that the rebound protection mechanism reduces the possibility of material rebounding and affecting people around after the ore is dumped. When the ore falls, it will press down the guide plate 15 and fall into the feed hopper 1. When the feeding is completed, the pressure on the top of the guide plate 15 disappears. Under the rebound force of the spring 13, the guide plate 15 will return to its original position. When material rebound occurs, the shielding effect of the guide plate 15 prevents the material from jumping out, reduces safety hazards, and improves the safety performance of the device.

[0032] The bottom end of the feed hopper 1 is provided with a discharge anti-jamming mechanism, which includes a roller 8. A plurality of transparent anti-jamming grooves 7 are provided on both sides of the bottom end of the feed hopper 1, and rollers 8 are rotatably connected between the upper and lower inner walls of the anti-jamming grooves 7.

[0033] It should be noted that, through the setting of the roller 8, the ore falls more smoothly to the outlet and is not easy to get stuck at the outlet, thereby improving the overall discharge rate.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
