[0030] The lower wall of the throwing machine body 23 is symmetrically provided with a shell clamping groove 237, a strip-shaped adsorption hole 2371 is formed in the top wall of the shell clamping groove 237, a rubber ring 2372 is fixedly arranged on the bottom wall of the shell clamping groove 237 outside the periphery of the strip-shaped adsorption hole 2371, and the strip-shaped adsorption hole 2371 is in through connection with the inner top wall of the locking cavity 231 through an adsorption pipe 238.

[0032] The lock hole 239 and the extrusion rod 2391 adopt the structure design in the Figure 7 , that is, the lock hole 239 limits the extrusion rod 2391, and the extrusion rod 2391 can slide in the lock hole 239 and will not completely slide out of the lock hole 239.

[0033] In specific use, the embodiment includes the following processes: loading, flight transportation and bomb throwing.

[0034] The loading process is as follows:

[0035] In the initial state, the long axis of the elliptical plate 2362 is in a horizontal state. The operator controls the laser emitter 11 to emit laser light. The photosensitive sensor 241 receives the laser signal. The steering engine 24 is controlled to operate and drive the bevel gear II 242 to rotate, thereby driving the bevel gear I 2361 to rotate by 90 degrees. The bevel gear I 2361 drives the rotating shaft 236 and the elliptical plate 2362 to rotate by 90 degrees. In this process, the long axis of the elliptical plate 2362 gradually changes from a horizontal state to a vertical state. The elliptical plate 2362 gradually contacts the sealing piston plate 234 and the converging plate 235, and pushes the sealing piston plate 234 upward and the converging plate 235 downward. The tension spring I 2332 and the tension spring II 2333 are stretched. During the upward sliding of the sealing piston plate 234, the lock tooth 2341 is driven to move. When the sealing piston plate 234 moves to the highest position, the lock tooth 2341 reaches the lock hole 239. Under the elastic force of the spring 2342, the lock tooth 2341 is clamped into the lock hole 239 and pushes the end of the extrusion rod 2391, so that the other end of the extrusion rod 2391 protrudes from the shell clamping groove 237. At this time, the space between the converging belt 230 and the shell clamping groove 237 is relatively loose, which facilitates the placement of the ammunition 3.

[0036] The operator takes two pieces of ammunition 3 and places them between the converging belt 230 and the shell clamping groove 237 on both sides, and then controls the steering engine 24 through the laser emitter 11 to reverse and reset, so that the elliptical plate 2362 reversely rotates by 90 degrees, that is, the long axis of the elliptical plate 2362 gradually rotates to a horizontal state. In this process, the sealing piston plate 234 is temporarily locked and cannot move because the lock tooth 2341 is clamped into the lock hole 239, while the tension spring II 2333 first contracts and drives the converging plate 235 to move upward, so that the converging belt 230 gradually tightens the ammunition 3. As the ammunition 3 is tightened, the outer wall of the ammunition 3 gradually tightens the outer wall of the ammunition 3 and the rubber ring 2372 outside the strip-shaped adsorption hole 2371, which blocks the outer end of the strip-shaped adsorption hole 2371. The outer wall of the ammunition 3 gradually pushes the extrusion rod 2391, so that the extrusion rod 2391 moves toward the lock tooth 2341, and gradually pushes the lock tooth 2341 out of the lock hole 239. When the lock tooth 2341 leaves the lock hole 239, the sealing piston plate 234 is no longer restricted, and the tension of the tension spring I 2332 causes the sealing piston plate 234 to slide downward, thereby suddenly reducing the internal pressure of the locking cavity 231 above the sealing piston plate 234, and reducing the air pressure in the strip-shaped adsorption hole 2371 through the connection of the adsorption pipe 238, so as to assist in adsorbing and locking the outer wall of the ammunition 3, and further improve the firmness of the ammunition 3.

[0037] The flight transportation process is as follows:

[0038] The drone 1 flies, driving the thrower 2 to fly, thereby transporting the ammunition 3 by air. During this process, tension spring 1 2332 and tension spring 2333 are continuously stretched, that is, tension spring 1 2332 and tension spring 2333 are continuously charged. If the flight turbulence causes the ammunition 3 to loosen between the cartridge case slot 237, the tension of tension spring 2333 can cause the gathering plate 235 to drive the gathering belt 230 to quickly tighten the ammunition 3, and tension spring 1 2332 can also continue to contract, so that the locking cavity 231 and the strip suction hole 2371 can once again suction and lock the ammunition 3.

[0039] The bombing process is as follows:

[0040] After UAV 1 reaches the designated location, it begins the bombing operation. The operator remotely controls the laser emitter 11 to emit a laser and controls the servo motor 24 to rotate the elliptical plate 2362 by 90 degrees. This causes the sealing piston plate 234 to move upward and the convergence plate 235 to move downward. The upward movement of the sealing piston plate 234 increases the air pressure in the locking cavity 231 and the strip-shaped suction hole 2371, so the strip-shaped suction hole 2371 no longer applies negative pressure to the ammunition 3. The downward movement of the convergence plate 235 causes one end of the convergence belt 230 to move, loosening the connection between the convergence belt 230 and the ammunition 3. At this time, the upper and lower sides of the ammunition 3 loosen simultaneously. Under the action of wind, the ammunition 3 automatically falls off, achieving the throwing. After the throwing is completed, UAV 1 drives the thrower 2 back to perform the next throwing operation.

[0041] Example 2: Figure 10 As shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, a cartridge case slot 237 is provided with three strip-shaped adsorption holes 2371, which are respectively connected to the adsorption tube 238. By providing three strip-shaped adsorption holes 2371, the outer wall of the ammunition 3 can be more reliably adsorbed and fixed.

[0042] The present invention and its embodiments have been described above. This description is not restrictive, and the figures shown are only one embodiment of the present invention. The actual structure is not limited to this.
