[0016] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "front", "back", "horizontal", and "vertical" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0018] It should be noted that the terms "horizontal" and "vertical" in this utility model are used to describe approximate positional relationships, and not strictly "horizontal plane" or "vertical plane".

[0019] like Figure 1-2As shown, an air hammer device for breaking bridges in a silo according to a preferred embodiment is provided, including: a housing 1 and a piston head 2. The housing 1 has a chamber inside, and the piston head 2 is movably disposed in the chamber and can be operably extended out of the housing 1.

[0020] Furthermore, in a preferred embodiment, one end of the outer casing 1 is provided with an air inlet 11, and the other end of the outer casing 1 is provided with an air outlet 12. The air inlet 11 and the air outlet 12 are respectively connected to the chamber. Furthermore, external compressed air can enter the chamber through the air inlet 11, and the air in the chamber can be discharged outwards through the air outlet 12. By providing the air outlet 12, it can be ensured that the air pressure at one end of the piston head 2 is greater than the air pressure at the other end of the piston head 2 after compressed air is input into the chamber, thereby enabling the piston head 2 to move away from the air inlet 11.

[0021] Furthermore, in a preferred embodiment, the piston head 2 includes a piston ring 21 and an impact hammer head 22. One end of the piston ring 21 and the impact hammer head 22 are detachably connected. The piston ring 21 is movably disposed in the chamber, and the other end of the impact hammer head 22 is operably extended out of the outer shell 1.

[0022] Furthermore, as a preferred embodiment, depending on the hardness of the material in the storage hopper 4, the impact hammer 22 can be made of materials with different hardness.

[0023] Furthermore, in a preferred embodiment, a sealing ring 23 is fitted around the piston ring 21, and the sealing ring 23 abuts against the inner wall of the chamber. Further, the sealing ring 23 is used to prevent compressed air located at one end of the piston head 2 from entering the chamber located at the other end of the piston head 2, thereby causing the pressure at both ends of the piston head 2 to be the same, and preventing the piston head 2 from moving.

[0024] Furthermore, as a preferred embodiment, it also includes: a control system 3, which is connected to the air inlet 11 and an external air source device.

[0025] Furthermore, as a preferred embodiment, the control system 3 is preferably configured as a solenoid valve, and the control system 3 can adjust the impact frequency and force of the impact hammer 22 by adjusting the flow rate of compressed air.

[0026] Furthermore, as a preferred embodiment, the air source device is preferably configured as an air compressor, which is used to provide compressed air.

[0027] Furthermore, as a preferred embodiment, one end of the outer casing 1 is bolted to the outer storage tank 4.

[0028] Furthermore, as a preferred embodiment, the impact hammer 22 is operably in contact with the outer wall of the storage tank 4.

[0029] Furthermore, in a preferred embodiment, a spring 5 is also included. The impact hammer 22 is surrounded by a spring 5, one end of which is connected to the piston ring 21, and the other end of which is connected to the inner wall of the chamber. Furthermore, the spring 5 provides elastic force to the impact hammer 22, allowing it to move towards the air inlet 11 under the action of the elastic force when no external compressed air is input.

[0030] The working principle of this utility model is as follows: the outer shell 1 is installed on the outer wall of the storage tank 4, and the air source device is controlled by the control system 3 to input compressed air into the chamber. The impact hammer 22 moves away from the air inlet 11 under the action of the compressed air and can impact the outer wall of the storage tank 4, thereby damaging the "bridging" inside the storage tank 4.

[0031] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
