[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4One embodiment provided by this utility model:

[0022] The first motor 16, the second motor 111, and the third motor 23 used in this application are products that can be purchased directly from the market. Their principles and connection methods are existing technologies well known to those skilled in the art, and therefore will not be described in detail here.

[0023] A ball mill with easy feeding control includes a body, which includes a base 1. A support frame 11 is fixedly connected to the upper surface of the base 1. A cylinder 12 is movably connected to the inner side of the support frame 11. A feeder 13 is fixedly connected to the top of the base 1 and is movably located inside the cylinder 12. A hopper 14 is fixedly connected to the top of the feeder 13. A screw conveyor 15 is movably connected to the inner side of the feeder 13. A first motor 16 is fixedly mounted on the surface of the feeder 13. The output end of the screw conveyor 15 and the first motor 16 are fixedly connected. A first gear 17 is fixedly connected to the surface of the cylinder 12. A fixing block 18 is fixedly connected to the upper surface of the base 1. A first rotating rod 19 is movably connected to the inner side of the fixing block 18. A second gear 110 is fixedly connected to the surface of the rotating rod 19, and a second motor 111 is fixedly installed on the surface of the fixed block 18. The output ends of the first rotating rod 19 and the second motor 111 are fixedly connected. Through the setting of the hopper 14, the material can enter the feeder 13. The first motor 16 drives the screw conveyor 15 to rotate, so that the material can be fed into the cylinder 12 under the action of the screw conveyor 15. The operation of the second motor 111 can drive the first rotating rod 19 to drive the second gear 110 to rotate. In turn, the rotation of the second gear 110 can drive the first gear 17 to rotate, so that the first gear 17 can drive the cylinder 12 to rotate. The material impacts inside the cylinder 12 and can be crushed.

[0024] A material control mechanism is provided at the top of the feeder 13. The material control mechanism includes a support plate 2, which is fixedly connected to the top of the feeder 13. A connecting block 21 is fixedly connected to the surface of the support plate 2, and a screw 22 is movably connected to the inner side of the connecting block 21. A third motor 23 is fixedly installed at the top of the support plate 2. A moving plate 24 is threadedly connected to the surface of the screw 22. A moving block 25 is fixedly connected to the surface of the moving plate 24. A fixed rod 26 is fixedly connected to the inner side of the moving block 25. A stop block 27 is fixedly connected to the bottom end of the fixed rod 26. By setting the stop block 27, the size of the gap formed between the stop block 27 and the inner wall of the hopper 14 will change when the stop block 27 moves vertically. This can achieve the effect of controlling the amount of material fed and prevent the crushing effect from being affected by too much material entering.

[0025] Furthermore, the screw 22 and the support plate 2 are movably connected, one end of the screw 22 is movably connected to the connecting block 21, and the other end of the screw 22 is fixedly connected to the output end of the third motor 23. By rotating the screw 22, the moving plate 24 can drive the moving block 25 to move vertically, thereby realizing the lifting and lowering of the stop block 27, which can adjust the size of the feeding gap of the hopper 14 and facilitate control of the amount of material entering.

[0026] Furthermore, the fixed rod 26 and the support plate 2 are movably connected. Both the fixed rod 26 and the stop block 27 are movable inside the hopper 14. By moving the fixed rod 26 inside the support plate 2, the moving block 25 and the moving plate 24 can be limited, which can prevent the moving plate 24 from shifting under the action of the screw 22, thereby ensuring the stable movement of the stop block 27.

[0027] Furthermore, a crushing mechanism is provided inside the cylinder 12. The crushing mechanism includes a second rotating rod 3, which is movably connected to the inside of the cylinder 12. A crushing rod 31 is fixedly connected to the surface of the second rotating rod 3. A connecting rod 32 is fixedly connected to the inner wall of the cylinder 12. A limit sleeve 33 is fixedly connected to the surface of the connecting rod 32. The rotation of the screw conveyor 15 causes the second rotating rod 3 to drive the crushing rod 31 to rotate, and the rotation direction is opposite to the rotation direction of the cylinder 12. As a result, the material can better collide inside the cylinder 12 under the action of the crushing rod 31, thus achieving a better crushing effect.

[0028] Furthermore, the second rotating rod 3 and the screw conveyor rod 15 are fixedly connected at the end away from the first motor 16. The crushing rod 31 is evenly distributed on the surface of the second rotating rod 3. By setting the second rotating rod 3, when the screw conveyor rod 15 rotates, the second rotating rod 3 can rotate under the action of the screw conveyor rod 15, thereby driving the crushing rod 31 to rotate and crush the material.

[0029] Furthermore, one end of the connecting rod 32 is fixedly connected to the cylinder 12, and the other end of the connecting rod 32 is fixedly connected to the limiting sleeve 33. The second rotating rod 3 moves inside the limiting sleeve 33. The cylinder 12 and the limiting sleeve 33 are connected by the connecting rod 32, so that the limiting sleeve 33 can limit the second rotating rod 3, which can ensure the stability of the rotation of the second rotating rod 3.

[0030] Working principle: During use, the third motor 23 is electrically connected to an external power source. The operator starts the third motor 23 by pressing the switch. The third motor 23 drives the screw 22 to rotate. Since the fixed rod 26 is limited by the support plate 2, the moving plate 24 will move vertically under the action of the screw 22. Then the moving block 25 moves accordingly, and the fixed rod 26 moves within the support plate 2. Thus, the stop block 27 rises and falls within the hopper 14 under the action of the fixed rod 26, so that the size of the gap between the stop block 27 and the hopper 14 will change, which can achieve the effect of material control.

[0031] When the screw conveyor 15 rotates, the second rotating rod 3 will rotate inside the cylinder 12 under the action of the screw conveyor 15 and move inside the limiting sleeve 33. The crushing rod 31 will rotate under the action of the second rotating rod 3, so that the rotation direction of the screw conveyor 15 and the cylinder 12 are opposite, and thus the rotation direction of the crushing rod 31 is opposite. The material can have better collision and impact, so the crushing rod 31 can crush the material in the opposite direction under the action of the screw conveyor 15.

[0032] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the description above. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
