[0026] The fixed rod barrel 1 is internally provided with a cavity, and the push rod 2 is slidably connected in the cavity;

[0027] The ejection assembly 3 is fixedly arranged at one end of the fixed rod barrel 1, and the other end of the ejection assembly 3 is connected to the push rod 2, so as to drive the push rod 2 to be ejected outward;

[0028] The electric control turntable assembly 4 is arranged below the fixed rod barrel 1, one end of the electric control turntable assembly 4 is movably connected to one end of the ejection assembly 3, and the electric control turntable assembly 4 is used to drive the ejection assembly 3 to automatically eject the push rod 2.

[0029] In the embodiment, the upper surface of the fixed rod barrel 1 is provided with the upper sliding groove 101 which is in communication with the cavity, and the front and rear sides of the fixed rod barrel 1 are both provided with the limiting sliding groove 102 which is in communication with the cavity.

[0030] In the embodiment, the ejection assembly 3 includes the U-shaped seat 301, the fixed shaft 302, the sliding column 303, the spring 304 and the limiting rod 305, the upper surface of the fixed rod barrel 1 is fixedly connected with the U-shaped seat 301, the fixed shaft 302 is fixedly arranged in the U-shaped seat 301, the upper surface of one end of the push rod 2 is fixedly connected with the sliding column 303 which is matched with the upper sliding groove 101, the spring 304 is fixedly arranged between the sliding column 303 and the fixed shaft 302, and the limiting rod 305 which is matched with the limiting sliding groove 102 is fixedly connected to the front and rear sides of one end of the push rod 2.

[0031] In the embodiment, the electric control turntable assembly 4 includes the mounting frame 401, the drive motor 402, the transmission shaft 403 and the cam 404, the lower surface of the fixed rod barrel 1 is fixedly arranged with the mounting frame 401, the mounting frame 401 is provided with the drive motor 402, the output end of the drive motor 402 is connected with the transmission shaft 403, the outer sides of the two ends of the fixed rod barrel 1 are provided with the cams 404, and the two ends of the transmission shaft 403 are fixedly connected with the cams 404.

[0032] In the embodiment, the cam 404 is movably connected with the limiting rod 305, the end of the push rod 2 is fixedly installed with a push plate 5, and the top and bottom of the fixed rod barrel 1 are fixedly connected with support frames 6.

[0033] In use, when the driving motor 402 drives the transmission shaft 403 to rotate clockwise, the transmission shaft 403 drives the cam 404 to rotate clockwise, and the arc surface of the cam 404 no longer extrudes the limiting rod 305 at this time, and meanwhile the spring 304 is no longer stretched, and under the reset action of the spring 304, the sliding column 303 slides in the upper sliding groove 101 of the fixed rod barrel 1 to the direction away from the U-shaped seat 301, and in the sliding process, the sliding column 303 can drive the push rod 2 to slide in the cavity, and in the sliding process, the push rod 2 can drive the limiting rod 305 to slide in the limiting sliding groove 102, and in the sliding process, the push rod 2 drives the push plate 5 to move to the direction away from the U-shaped seat 301.

[0034] Similarly, when the driving motor 402 drives the transmission shaft 403 to rotate counterclockwise, the arc surface of the cam 404 begins to extrude the limiting rod 305, so that the limiting rod 305 moves in the limiting sliding groove 102 to the direction away from the U-shaped seat 301, and in the sliding process, the limiting rod 305 can drive the push rod 2 to move, so that in the moving process, the push rod 2 can drive the push plate 5 to move to the direction close to the U-shaped seat 301, and in the moving process, the push rod 2 can also drive the sliding column 303 to move, and in the moving process, the sliding column 303 stretches the spring 304, so that the spring 304 is in a stretched state.

[0035] Therefore, when the driving motor 402 drives the cam 404 to rotate clockwise first, the push plate 5 moves to the direction away from the U-shaped seat 301, and after the push plate 5 moves to the maximum stroke, the driving motor 402 drives the cam 404 to rotate counterclockwise, so that the push plate 5 moves to the direction close to the U-shaped seat 301, and under the driving of the driving motor 402, the push plate 5 performs reciprocating motion.

[0036] In summary, the automatic ejection device for the air cannon has the advantages that the driving motor 402 drives the cam 404 to rotate forward or reversely, so that the limiting rod 305 is in the abutting limiting state and the separation state under the action of the cam 404, the spring 304 automatically resets and automatically ejects the push rod 2, manual operation is avoided, and the device has certain practicability.

[0037] All the technical features in the embodiment can be freely combined according to actual needs.

[0038] The above embodiment is a preferred implementation scheme of the utility model, and the utility model can also be implemented in other manners, and any obvious replacement without departing from the technical scheme concept is within the protection scope of the utility model.
