[0050] The present application can be used in the technical field of bridge breaking devices, and can also be used in other fields applicable to the present application.

[0051] Example 2: Reference Figure 2 , 3 6. Improvement on the basis of Example 1: an adjustable bridge-breaking device for auxiliary container unloading, which is applied to the technical field of bridge-breaking devices;

[0052] In order to limit the rotation range of the movable rod 3, in this embodiment, an arc-shaped limit groove 11 is provided on one side of the first movable bracket 4, and a limit column 12 is fixedly installed on one side of the second movable bracket 5. The limit column 12 slides with the inner wall of the arc-shaped limit groove 11, thereby limiting the rotation range of the movable rod 3. The rotation angle of the movable rod 3 is 25° to 45°.

[0053] In order to ensure the stable placement of the device, in this embodiment, two second fixing plates 23 are fixedly installed on both sides of the bottom plate 19, and the insides of the second fixing plates 23 are provided with mounting holes 24. Multiple second fixing plates 23 can be used to complete the connection between the base 8 and the external device.

[0054] However, as is well known to those skilled in the art, the working principles and wiring methods of the cylinder 2 and the motor 30 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.

[0055] The use process and working principle of the technical solution of the present invention are as follows:

[0056] When in use, the device can be used in conjunction with the discharging device 37. A hopper 38 is provided below the discharging port of the discharging device 37. The device is arranged next to the discharging device. When the hopper 38 is transported to the bottom of the discharging device 37 and the discharging operation needs to be performed, the cylinder 2 is limited to the initial position through the magnetic switch. After the hopper 38 is in place, the cylinder 2 and the magnetic switch are disconnected, and the cylinder 2 is started to move the movable rod 3 from the initial position to the knocking position, so that the knocking piece 10 knocks the discharging device 37 and performs repeated knocking movements to break the bridge of the material. At the same time, before use, the user can adjust the position of the movable rod 3 from the initial position to the knocking position according to the specific conditions of the discharging device 37. The position of the column bracket 1 can be adjusted accordingly according to the specifications. After the user has placed the equipment, the user can move the mobile box 7 in the base 8 to make fine adjustments to the position of the column bracket 1. The user can start the motor 30, and the motor 30 can drive the driving gear 32 to rotate through the rotating shaft 31. The driving gear 32 is meshed with the second gear 28 at this time, and then the third gear 29 can be driven to rotate. Then, with the cooperation of the third gear 29 and the rack 22, the sliding of the mobile box 7 inside the base 8 can be realized, so that the striking piece 10 can better realize the discharge. When the user needs to adjust the height of the column bracket 1, the user only needs to step on the pedal 35, and the pedal 35 can drive the movable plate 33 and the driving gear 32 to descend synchronously. At this time, the driving gear 32 is engaged with the first gear 27, and then the user starts the motor 30 again, and the driving gear 32 can drive the threaded rod 26 to rotate, so that the movable plate 18 can be lifted and lowered in the support rod 6, and the movable plate 18 can drive the column bracket 1 to be lifted and lowered synchronously, which can ensure that the striking piece 10 can cooperate with the discharging devices 37 of different specifications; when the user stops After stepping on the pedal 35, under the action of the spring 36, the movable plate 33 will drive the driving gear 32 to move up again and make the driving gear 32 mesh with the second gear 28 again, which can ensure the subsequent normal adjustment of the position of the movable box 7; when using the device, the user can use the second fixing plates 23 on both sides of the base 8 and the corresponding mounting holes 24 to connect the base 8 with an external counterweight object or equipment, which can ensure that the base 8 can be stably placed on the ground, and can prevent the device from tipping over due to the change of the center of gravity after adjustment, which is conducive to the stable operation of the striking member 10.

[0057] Among them, the striking piece 10 strikes the discharging device 37 to perform repeated striking motions using a circuit structure, which belongs to the prior art. For example, the striking piece 10 can repeatedly strike the discharging device 37 by repeatedly opening and closing the circuit through capacitor charging and discharging. There are other ways to perform repeated motions, which will not be repeated here.
