Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Embodiment

[0029] Please refer to Figures 1 - 4 , the present utility model provides the following technical solutions:

[0030] An impact-resistant lining plate for a ball mill includes:

[0031] Device housing 1;

[0032] Impact-resistant blocks 2, there are multiple impact-resistant blocks 2, and multiple impact-resistant blocks 2 are all fixedly connected to the circumferential surface of the impact lining plate 13;

[0033] Sliding grooves 3, there are multiple sliding grooves 3, and multiple sliding grooves 3 are respectively opened in multiple impact-resistant blocks 2;

[0034] Sliders 4, there are multiple sliders 4, and multiple sliders 4 are respectively slidably connected in multiple sliding grooves 3;

[0035] First springs 5, there are multiple first springs 5, and multiple first springs 5 are respectively fixedly connected to the rear ends of multiple sliders 4.

[0036] In a specific embodiment of the present utility model, for the device housing 1, its core features lie in the layout of the impact-resistant blocks 2 and the dynamic support mechanism. Specifically, multiple impact-resistant blocks 2 are fixed on the circumferential surface of the impact lining plate 13, aiming to disperse and absorb the impact force generated during the operation of the mill and protect the equipment body. Each impact-resistant block 2 is embedded with a sliding groove 3, and these grooves provide tracks for the sliders 4, enabling multiple sliders 4 to slide freely along their respective sliding grooves 3. This design endows the system with good adaptability and buffering ability to impacts from different directions. Further, the rear end of each slider 4 is equipped with a first spring 5. These first springs 5 not only match the number of sliders 4 but also effectively absorb and relieve the instantaneous impact energy acting on the impact-resistant blocks 2 through the conversion of elastic potential energy, thereby reducing the impact force directly transmitted to the equipment main body and enhancing the stability and durability of the system. This design realizes the effective buffering and dispersion of mechanical impacts through the linkage between components, ensuring the smooth operation and efficiency of the ball mill, and at the same time extending the service life of the equipment.

[0037] Specifically, please refer to Figures 1 - 4 , the upper ends of multiple sliders 4 are respectively fixedly connected with multiple first mating rotators 6, and multiple first rotating shafts 7 are respectively rotatably connected in multiple first mating rotators 6.

[0038] In this embodiment: a group of first matching rotators 6 are fixedly mounted on the upper ends of the plurality of sliders 4, and a first rotating shaft 7 matching therewith is disposed inside each group of first matching rotators 6, and these first rotating shafts 7 can rotate freely in their corresponding first matching rotators 6. This structural design promotes the mechanical linkage between the sliders 4 and the first rotating shafts 7: when the sliders 4 slide along the sliding grooves 3, power is transmitted through the first matching rotators 6, causing the first rotating shafts 7 to rotate accordingly, thereby realizing the conversion from linear motion to rotational motion.

[0039] For details, please refer to Figures 1 - 4 A plurality of rotating arms 8 are respectively fixedly connected to the circumferential surfaces of the plurality of first rotating shafts 7 , and a plurality of second rotating shafts 9 are respectively fixedly connected inside the plurality of rotating arms 8 .

[0040] In this embodiment, a series of rotating arms 8 are fixedly mounted on the outer circumferential surfaces of the plurality of first rotating shafts 7, and the second rotating shafts 9 are further fixed inside the rotating arms 8. With such an arrangement, when the first rotating shafts 7 rotate with the movement of the slider 4 and the action of the first matching rotator 6, their kinetic energy is transmitted to the connected rotating arms 8, thereby driving the respective built-in second rotating shafts 9 to rotate synchronously.

[0041] For details, please refer to Figures 1 - 4 The circumferential surfaces of the plurality of second rotating shafts 9 are respectively rotatably connected with a plurality of second matching rotators 10.

[0042] In this embodiment, the circumferential edges of the plurality of second rotating shafts 9 are each equipped with a rotatably connected second matching rotator 10. This configuration enables the rotational motion of each second rotating shaft 9 to be further accurately transmitted through the second matching rotator 10.

[0043] For details, please refer to Figures 1 - 4 The lower ends of the plurality of second matching rotators 10 are respectively fixedly connected with a plurality of second springs 11 , and the plurality of anti-impact blocks 2 are respectively fixedly connected with a plurality of second springs 11 .

[0044] In this embodiment: multiple second springs 11 are fixedly mounted on the lower end surfaces of the multiple second matching rotators 10, and at the same time, these second springs 11 are also directly fixed inside each anti-impact block 2. This arrangement allows the rotation of the second matching rotators 10 to effectively absorb and mitigate the vibration and impact force during the transmission process through the elastic deformation of the second springs 11, providing additional buffer protection for the entire mechanical structure.

[0045] For details, please refer to Figures 1 - 4 The upper ends of the multiple second matching rotators 10 are respectively fixedly connected with multiple docking devices 12, the upper ends of the multiple docking devices 12 are all fixedly connected with impact lining plates 13, and the inner walls on both sides of the multiple impact-resistant blocks 2 are respectively fixedly connected with multiple first springs 5.

[0046] In this embodiment: At the top of each of the multiple second cooperating rotators 10, a plurality of docking connectors 12 are fixedly connected respectively, and the upper parts of these docking connectors 12 jointly and fixedly support the impact lining plate 13. At the same time, a plurality of groups of first springs 5 are provided on the inner walls on both sides of the impact-resistant block 2, which further stabilize the system structure. This series of designs enables the rotational movement of the second cooperating rotator 10 to be smoothly transmitted to the impact lining plate 13, and when encountering external impacts, the first springs 5 and the second springs 11 act together, not only strengthening the absorption and dispersion of impact energy, but also ensuring the firmness and dynamic adaptability of the connection between the impact lining plate 13 and the impact-resistant block 2.

[0047] The working principle and usage process of the present utility model: When the ball mill is working, the material enters the device housing 1, during which the impact-resistant blocks 2 are evenly distributed and fastened to the circumferential surface of the impact lining plate 13 to withstand the impact force during the grinding process. As the material moves, the slider 4 embedded in the sliding groove 3 slides along the groove, and the first spring 5 at its rear end provides buffering to reduce the direct impact on the machine body. The first rotating shaft 7 embedded in the first cooperating rotator 6 at the top of the slider 4 rotates as the slider 4 moves, further transmitting the energy. The first rotating shaft 7 drives the second rotating shaft 9 to rotate through the rotating arm 8, increasing the level and flexibility of force transmission. The second cooperating rotator 10 outside the second rotating shaft 9 not only transmits power, but the second spring 11 connected to its lower end also jointly enhances the shock absorption effect with the second spring 11 preset in the impact-resistant block 2. Finally, the second cooperating rotator 10 is firmly connected to the impact lining plate 13 via the docking connector 12 to ensure the coordinated operation of all components, and the first springs 5 on both sides of the impact-resistant block 2 reinforce the overall structure, improving the system's resistance to impacts, ensuring the efficient and stable operation of the ball mill, while reducing maintenance costs and equipment wear. By using this device, the problem of the traditional ball mill's impact-resistant lining plate 13 not improving the durability inside the barrel by adding an internal shock rebound mechanism is solved, so this function cannot be achieved, resulting in a reduction in the service life of this device. And this device has the characteristic of adding an internal shock rebound mechanism, which can absorb or relieve impacts and vibrations, thereby reducing the direct impact and fatigue damage to the barrel body, and further achieving the purpose of increasing the service life of this device.

[0048] Finally, it should be noted that: The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
