[0026] 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.

[0027] Example: As attached Figures 1-8 As shown, an automatic furnace dismantling machine includes a main plate 1. The main plate 1 is connected to a positioning system for fixing the entire machine and an impact system for dismantling the furnace. The main plate 1 is the main body of the entire machine. A lifting chain 2 is installed above the main plate 1 to suspend the machine. An electric hoist 3 is installed at the upper end of the lifting chain 2 for lifting the machine. Four sets of support assemblies are connected to the main plate 1 and are evenly distributed around the main plate 1 for use when placing the machine.

[0028] like Figure 1 , 2 As shown in Figure 8, the bracket assembly includes a bracket rod 4 and a bracket base 5. The bracket base 5 is welded to the main plate 1 as a support point. The bracket rod 4 and the bracket base 5 are hinged together by a support shaft, allowing the bracket rod 4 to rotate up and down around the shaft. During operation, the bracket rod 4 rotates to the top dead center. During placement, the bracket rod 4 rotates to the bottom dead center. Tension springs tighten the bracket rod at both the top and bottom dead centers.

[0029] like Figure 3As shown, the positioning system comprises a supporting rail 6 fixedly connected with the main plate 1, a positioning needle 7 which can slide along the supporting rail 6, and a positioning motor 8 which drives the movement of the positioning needle 7.

[0030] The positioning motor 8 is located at the center of the main plate 1, and is installed in a positioning motor cover and fixedly connected with the main plate 1. The motor shaft penetrates downward through the main plate 1, and the shaft end is provided with a driving bevel gear 9. The positioning needle 7 is provided with multiple groups and symmetrically arranged. In this embodiment, two groups are provided, and other groups can also be provided according to specific conditions. Each positioning needle 7 is arranged radially along the main plate 1. The positioning needle 7 is assembled in the supporting rail 6 and can freely slide. The positioning needle 7 is fixedly provided with a nut 11 at the end close to the center of the main plate 1. The nut 11 is connected with a matched screw rod 12 which is arranged in parallel with the positioning needle 7. The screw rod 12 is fixedly provided with a driven bevel gear 10 at the end close to the center of the main plate 1. The driving bevel gear 9 on the positioning motor 8 engages with the driven bevel gear 10. Through the forward and reverse rotation of the positioning motor 8, the extension and retraction functions of the positioning needle 7 are achieved.

[0031] As shown in the figure, Figures 4-5 The impact system comprises an impact plate 13 arranged in parallel with the main plate 1 and a pneumatic pick 14 installed on the impact plate 13. The impact plate 13 is located below the main plate 1 and connected with the main plate 1 through a pipe shaft 15. The pipe shaft 15 is located at the center of the main plate 1 and the impact plate 13. The pipe shaft 15 is fixedly connected with the main plate 1, and in this embodiment, the pipe shaft 15 is welded with the main plate 1 as a whole. The impact plate 13 is installed in the middle end of the pipe shaft 15 through a thrust bearing and fastened at the lower end of the pipe shaft 15 by a cap. The impact plate 13 is also fixedly provided with a rotating motor 16. The motor shaft of the rotating motor 16 penetrates through the impact plate 13 and is fixedly provided with a driving gear 17 on the impact plate 13. A driven gear 18 is fixedly provided on the upper end of the pipe shaft 15. The driving gear 17 engages with the driven gear 18. The forward and reverse rotation of the rotating motor 16 achieves the function of driving the whole rotating plate to rotate forward and reversely.

[0032] As shown in the figure, Figures 5-7 The pneumatic pick 14 is fixedly provided on the impact plate 13. The pneumatic pick 14 comprises a main body shell 19 fixedly connected with the impact plate 13, an impact cylinder body 20 in the main body shell 19, and an impact piston 21 in the impact cylinder body 20. The end of the impact piston 21 away from the center of the impact plate 13 is connected with an impact head 22. The structure in the pneumatic pick 14 and the gas flow direction are consistent with the prior art, and are not described in detail.

[0033] The external air source switch is turned on, the cylinder body is pushed forward, and at the same time, air enters the impact cylinder body 20 to further push the impact piston 21 forward. At this time, the cylinder body is forced to move forward, and the impact piston 21 drives the impact head 22 to move forward, thereby completing the destruction of the sintered layer.

[0034] As shown in the figure, Figure 6As shown, a depth gauge 23 is also fixedly connected to the impact cylinder 20. The depth gauge 23 is connected to the side near the impact head 22 and is set parallel to the impact head 22. When the impact head 22 impacts the sintered layer, the depth gauge 23 can be used to limit the impact to prevent excessive impact from damaging the induction coil.

[0035] like Figure 5 and Figure 7 As shown, a pneumatic lever 24 is also connected to the main body shell 19. A shell 25 is fitted around the outside of the pneumatic lever 24. The pneumatic lever 24 can slide along the shell 25 under the push of gas. One end of the shell 25 is fixed to the main body shell 19, and the other end of the pneumatic lever 24 is fixed to the impact cylinder 20. The end of the shell 25 near the impact cylinder 20 is provided with a pneumatic lever air inlet 26 that is connected to an external air source. When an impact point is completed, the air source of the pneumatic lever 24 is turned on, and the pneumatic lever 24 pulls the impact cylinder 20 back to its original position. This process is repeated continuously.

[0036] In use, the equipment is lifted using the electric hoist 3. The support rod 4 is folded upwards to avoid obstructing the rotation of the impact assembly. The equipment is then suspended and placed into the crucible, and dismantling begins from the bottom and proceeds layer by layer upwards. After the equipment is started, the positioning assembly extends outwards via the positioning motor 8, and the positioning pin 7 embeds into the sintered layer of the crucible. The two positioning assemblies are installed symmetrically to keep the equipment centered. After positioning, the impact assembly extends outwards under air pressure and begins impact. After the first impact point is completed, the impact assembly retracts and rotates slightly via the rotary motor 16 to impact the second point, and so on to complete the first round of impact. After the first round of impact is completed, the positioning assembly retracts, and the equipment is slightly lifted upwards via the electric hoist 3 to begin the second round of dismantling. This process continues until the equipment is dismantled from the bottom to the top. The equipment is then removed, and the broken material is cleaned up, completing the dismantling process.
