[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-3, the utility model provides an embodiment: a high wear-resistant impact cone of a pneumatic impact regeneration machine, including a cone 1, the top of the cone 1 is rotatably connected to a rotating disk 2, the inner wall of the rotating disk 2 is fixedly connected with 3, the internal thread of 3 is connected with a threaded rod 4, the upper surface of the cone 1 is fixedly connected with a positioning block 5, the outer wall of the positioning block 5 is slidably connected with a fixed rod 6, one end of the threaded rod 4 is rotatably connected with a push block 7, the outer wall of the push block 7 is slidably connected with a clamping block 8, the outer wall of the clamping block 8 is slidably connected to the inside of the positioning block 5 and the fixed rod 6, the inside of the clamping block 8 is rotatably connected with a rotating block 9, the outer wall of the rotating block 9 is fixedly connected with a telescopic rod 10, the outer wall of the telescopic rod 10 is sleeved with a spring 11, both ends of the spring 11 are fixedly connected to the outer wall of the rotating block 9, and an anti-wear component is arranged at the bottom of the cone 1;

[0025] Specifically, first rotate the rotating disk 2, thereby driving 3 to rotate inside the cone 1 through the rotating disk 2. The rotation causes 3 to move relative to the inner wall of the cone 1, thereby generating friction. The friction drives the threaded rod 4 to move inside the cone 1 and the positioning block 5. As the threaded rod 4 moves, it pushes the push block 7 to move forward or backward inside the positioning block 5. In this process, the push block 7 will apply a forward force to the card block 8, so that the card block 8 slides inside the positioning block 5 and the fixing rod 6. This sliding allows the card block 8 to be stably fixed inside the positioning block 5, thereby realizing the installation of the card block 8. When the card block 8 needs to be removed, it is only necessary to rotate the rotating disk 2 in the opposite direction. At this time, the spring 11 generated between the rotating block 9 and the rotating disk 2 will generate a reverse force to pull the card block 8 back from the positioning block 5. This design makes the installation and removal process of the card block 8 simple and convenient, and greatly improves the work efficiency.

[0026] Reference Figure 1 The anti-wear component includes an arc-shaped protrusion 12, and the outer wall of the arc-shaped protrusion 12 is fixedly connected to the bottom of the cone 1;

[0027] Specifically, an arc-shaped protrusion 12 is designed at the bottom of the cone 1 to reduce the force range of the cone 1 when it is subjected to impact, thereby improving its wear resistance, helping the cone 1 to maintain its structure and shape for a longer time, and reducing wear or deformation caused by frequent impacts.

[0028] Reference Figure 4-5The top of the cone 1 is fixedly connected with a positioning ring 13, the inner wall of the positioning ring 13 is slidably connected to the outer wall of the fixed rod 6, the interior of the positioning ring 13 is slidably connected with a rotating plate 14, the inner wall of the rotating plate 14 is fixedly connected with a rotating bar 15, the interior of the rotating bar 15 is slidably connected with a sliding rod 16, the outer wall of the sliding rod 16 is fixedly connected with a push plate 17, the upper surface of the push plate 17 is fixedly connected with a limiting bar 18, the outer wall of the limiting bar 18 is slidably connected to the interior of the positioning ring 13, the outer wall of the push plate 17 is fixedly connected with a positioning plate 19, the interior of the rotating bar 15 is slidably connected with a telescopic rod 20, one end of the telescopic rod 20 is slidably connected to the interior of the positioning ring 13, the outer wall of the telescopic rod 20 is fixedly connected with a sliding plate 21, the outer wall of the sliding plate 21 is slidably connected to the interior of the rotating bar 15, and the outer wall of the telescopic rod 20 is sleeved with a spring 22, one end of the spring 22 is fixedly connected to the interior of the rotating bar 15, and the other end of the spring 22 is fixedly connected to the outer wall of the sliding plate 21;

[0029] Specifically, the cone 1 is connected to the rotating plate 14 through a rotating positioning ring 13. When the rotating plate 14 is rotated, the rotating bar 15 is driven to rotate inside the positioning ring 13. The design allows the cone 1 to have a certain flexibility when it is impacted, while maintaining the stability of its position. Inside the rotating bar 15, there is an arc-shaped slide groove, in which the slide rod 16 can slide. When the rotating bar 15 rotates, the slide rod 16 will slide in the arc-shaped slide groove, thereby pushing the push plate 17. The function of the push plate 17 is to push the positioning plate 19 to a position that fits the cone 1 and the fixed rod 6. The four positioning plates 19 are designed to ensure that the cone 1 and the fixing rod 6 always remain vertical. When the cone 1 is impacted, the four positioning plates 19 will move as needed to maintain the verticality between the cone 1 and the fixing rod 6 to prevent the cone 1 from shifting or tilting. Finally, a spring 22 is installed inside the rotating bar 15. When the impact is over, the spring 22 will push the telescopic rod 20 to the inside of the positioning ring 13 to keep the impact cone in a vertical working state. This design can ensure that the cone 1 always maintains the correct position during continuous impacts to avoid damage caused by offset.

[0030] Working principle: When the high wear-resistant impact cone of the pneumatic impact regeneration machine is needed, first, by rotating the rotating disk 2, the drive 3 rotates inside the cone 1, thereby driving the threaded rod 4 to move inside the cone 1 and the positioning block 5, and then driving the push block 7 to move inside the positioning block 5. At the same time, pressure is applied to the card block 8, so that the card block 8 slides inside the positioning block 5 and the fixed rod 6 to achieve installation, and then by rotating the rotating disk 2 in the opposite direction, the spring 11 between the rotating block 9 pulls the card block 8 back to the inside of the positioning block 5, achieving the effect of convenient disassembly and assembly, and then through the arc-shaped protrusion 1 at the bottom of the cone 1 2 reduces the force range of the impact cone, thereby improving the wear resistance, and finally, by rotating the rotating plate 14 on the outer wall of the positioning ring 13, the rotating bar 15 is driven to rotate inside the positioning ring 13, so that the sliding rod 16 slides in the arc-shaped sliding groove inside the rotating bar 15, and then the positioning plate 19 is pushed to fit with the cone 1 and the fixed rod 6 through the push plate 17. In this process, the cone 1 and the fixed rod 6 are kept vertical by the movement of the four positioning plates 19. Finally, the telescopic rod 20 is pushed to the inside of the positioning ring 13 by the spring 22 inside the rotating bar 15 to achieve the vertical operation of the impact cone to avoid damage caused by deviation.

[0031] 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 substitutions for some of the technical features therein.
