[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1 and Figure 2 , the utility model provides an embodiment: an iron ore crushing device, including a feed frame 1, the outer wall of the feed frame 1 is fixedly connected to a support plate 2, the top of the support plate 2 is fixedly connected to a fixed plate 3, one side of the fixed plate 3 is fixedly connected to a first motor 4, the output end of the first motor 4 is fixedly connected to a gear 6, the top of the support plate 2 is fixedly connected to two left-right symmetrical support rings 7, the interior of the support ring 7 is slidably connected to a slide column 8, one end of one slide column 8 is fixedly connected to a rack 2 9, and one end of the other slide column 8 is fixedly connected to a rack 1 5, and the rack 1 5 and the rack Rack 2 9 is meshed with gear 6, and one side of rack 2 9 and rack 1 5 is fixedly connected to a connecting block 10, and one side of the connecting block 10 is fixedly connected to a second motor 12, and the output end of the second motor 12 is fixedly connected to a support rod 13, and a crushing assembly is provided on the outer wall of the support rod 13. The crushing assembly is used to crush the iron ore, and the crushing assembly includes a crushing rod 14, which is fixedly connected to the outer wall of the support rod 13, and the crushing rod 14 is rotatably connected to the inside of the feed frame 1. A chute 11 is provided inside the feed frame 1, and the support rod 13 is slidably connected to the inside of the chute 11.

[0033] Specifically, during the crushing process, when it is necessary to adjust the spacing between the crushing rods 14 according to specific needs, the gear 6 is first driven to rotate through the output end of the first motor 4. The gear 6 is driven by the force to drive the rack 2 9 and the rack 1 5 that are meshed with the outer wall to start moving. The rack 2 9 and the rack 1 5 respectively drive the connecting block 10 connected on one side. Under the action of force, the connecting block 10 pushes the second motor 12 connected on one side to move. The two second motors 12 slide inside the slide 11 through the support rods 13 connected to the output ends respectively. The two support rods 13 then drive the crushing rods 14 on the outer wall to move, thereby realizing the precise adjustment of the spacing between the crushing rods 14. Subsequently, the crushing rods 14 are continued to be driven by the output end of the second motor 12 for rotational crushing, thereby effectively realizing the flexible adjustment of the crushing spacing during the crushing process, ensuring that the ore can be precisely crushed to the required size, thereby improving the efficiency and quality of the production process.

[0034] Reference Figure 1 、 Figure 3 and Figure 4A third motor 20 is fixedly connected to one side of the lower hopper 15, and a rotating column 21 is fixedly connected to the output end of the third motor 20. The rotating column 21 is rotatably connected to the inside of the lower hopper 15. A push plate 22 is fixedly connected to the outer wall of the lower hopper 15. A connecting frame 23 is fixedly connected to the inside of the lower hopper 15, and the push plate 22 is slidably connected to the inside of the connecting frame 23.

[0035] Specifically, after the crushing is completed, the crushed material will first fall into the lower hopper 15 at the bottom of the feed frame 1 and be concentrated on the connecting frame 23. Then, the output end of the third motor 20 drives the rotating column 21 to start rotating. The rotating column 21 drives the push plate 22 connected to the outer wall to move inside the connecting frame 23, thereby achieving the effect of motion transmission.

[0036] Reference Figure 1 、 Figure 3 and Figure 4 The bottom of the feeding frame 1 is fixedly connected to a lower hopper 15, the bottom of the lower hopper 15 is fixedly connected to a conveying frame 16, the outer wall of the conveying frame 16 is fixedly connected to a motor 18, the output end of the motor 18 is fixedly connected to a spiral blade 17, the spiral blade 17 is rotatably connected to the inside of the conveying frame 16, and the outer walls of the feeding frame 1 and the lower hopper 15 are fixedly connected to a support frame 19.

[0037] Specifically, the movement of the push plate 22 pushes the crushed material on the connecting frame 23 to slide into the empty slot inside the connecting frame 23, and finally falls into the conveying frame 16 in the bottom lower hopper 15, ensuring smooth passage of the material and avoiding blockage problems during the conveying process. Subsequently, the output end of the motor 18 drives the spiral blade 17 to rotate inside the conveying frame 16. The rotation of the spiral blade 17 pushes the crushed material forward smoothly, ensuring the continuous conveying effect of the material.

[0038] Working principle: During the crushing process, when the spacing of the crushing rods 14 needs to be adjusted according to demand, the gear 6 is first driven to rotate by the output end of the first motor 4. The gear 6 is driven by the force to drive the rack 2 9 and the rack 1 5 that are meshed with the outer wall to move. The rack 2 9 and the rack 1 5 are respectively driven by the force to drive the connecting block 10 connected on one side to move. The connecting block 10 is driven by the force to drive the second motor 12 connected on one side to move. The two second motors 12 respectively drive the support rods 13 connected to the output end to slide inside the slide groove 11. The two support rods 13 are respectively driven by the force to drive the crushing rods 14 on the outer wall to move, thereby adjusting the spacing between the two crushing rods 14. Subsequently, the crushing rods 14 are driven by the output end of the second motor 12 to rotate and crush, thereby achieving the goal of adjusting the size of the crushed pieces. The effect of row regulation is that after crushing is completed, the material will fall into the lower hopper 15 at the bottom of the feed frame 1 and fall on the connecting frame 23 inside the lower hopper 15. At this time, the output end of the third motor 20 drives the rotating column 21 to rotate, and the rotating column 21 is driven by the force to drive the push plate 22 connected to the outer wall to move inside the connecting frame 23. The movement of the push plate 22 pushes the crushed material on the connecting frame 23 to move, so that it falls into the conveying frame 16 at the bottom of the lower hopper 15 through the empty slot inside the connecting frame 23, thereby dredging the material and avoiding blockage during transportation. Subsequently, the spiral blade 17 is driven by the output end of the motor 18 to rotate inside the conveying frame 16, and the movement of the spiral blade 17 pushes the material to achieve the conveying effect.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
