As shown in fig. 1-8, a stroller according to the present embodiment. The stroller includes a launch device.

The firing device includes a frame 100, a firing device, a barrel 200, a transfer device 400, and a magazine 500.

The transfer device 400, magazine 500, barrel 200, and firing device are mounted to the chassis 100. The bullet storage bin 500 is provided with a bullet storage cavity 501, a bullet outlet 502 and a bullet loading opening 503 which are communicated with the bullet storage cavity 501, the bullet outlet 502 is connected with a transmitting device by the transmitting device 400, the transmitting device is used for accelerating the projectile 700 to be transmitted, and the gun barrel 200 is in butt joint with the transmitting device. The pellets 700 are loaded into the storage chamber 501 from the loading opening 503, fall into the conveying device 400 from the ejection opening 502, the conveying device 400 conveys the pellets 700 to the ejection device, the ejection device accelerates the pellets 700 and ejects the pellets 700, the pellets 700 are ejected by the ejection device and then enter the gun barrel 200, and finally are ejected from the gun barrel 200.

The transfer device 400 is used for transferring the pellets 700. The conveying device 400 comprises a conveying belt 410 and a conveying wheel 420 for tightening the conveying belt 410, and two ends of the conveying belt 410 are respectively butted with the bullet outlet 502 and the launching channel 330. The second motor 640 drives the transfer wheel 420 to rotate through the gear set 430, thereby driving the transfer belt 410 to rotate and convey the pellets 700.

The launching device is used to accelerate the projectile 700 and launch the projectile 700. The launching device comprises two rotating wheels 310 with opposite directions of rotation. The rotating wheels 310 mean that the rotating wheels 310 can rotate relative to the frame 100, and the first motors 320a and 320b each drive one rotating wheel 310, so that the two rotating wheels 310 rotate in opposite directions when the projectile 700 is launched, as shown by the arrow direction in fig. 2. The rotating wheel 310 may be not only a driving wheel but also a driven wheel, not limited to the present embodiment. Between the two rotating wheels 310, a firing channel 330 for the projectile 700 is formed, and the barrel 200 is docked with the firing channel 330. When the pellets 700 are fed to the firing channel 330 between the two rotating wheels 310, the two rotating wheels 310 rotate in opposite directions, the pellets 700 are accelerated by the rotating wheels 310 to be fired, and the accelerated pellets 700 enter the gun barrel 200, and finally the pellets 700 are ejected from the gun barrel 200. The barrel 200 interfaces with the firing channel 330 and the projectiles 700 enter the barrel 200 through the firing channel 330 of the firing device and are ejected from the barrel 200.

The striking part 630 is long, one end of which is connected with the rotating arm 620 and the other end of which is suspended in the magazine 500. As the stirring member 600 rotates within the magazine 500, the striking portion 630 suspended within the magazine 501 is better able to strike the projectile 700. When the stirring member 600 rotates until the stirring portion 630 approaches the ejection opening 502, the width between the stirring portion 630 and the ejection opening 502 is smaller than 1.5 times the width of the ejection opening 502, wherein the width between the stirring portion 630 and the ejection opening 502 is as shown in fig. 8. When the stirring member 600 rotates until the stirring portion 630 abuts against the ejection opening 502, a channel for passing the pellets 700 is formed between the stirring portion 630 and the ejection opening 502, and the width between the stirring portion 630 and the ejection opening 502 only allows one pellet 700 to pass through, so that the pellets 700 can be prevented from being stacked on the ejection opening 502 to cause the pellets 700 to not pass through the ejection opening 502 smoothly, and preferably, the width between the stirring portion 630 and the ejection opening 502 is smaller than 1.5 times of the width of the ejection opening 502. The "width" between the toggle portion 630 and the ejection opening 502 and the "width" of the ejection opening 502 refer to the distance that allows the shot 700 to pass through, for example, the diameter of the ejection opening 502 with a circular shape if the ejection opening 502 is a circular shape, the length of the short side of the ejection opening 502 with a square shape if the ejection opening 502 is a square shape, the short axial length of the ejection opening 502 with an elliptical shape if the ejection opening 502 is an elliptical shape, and so on.

The ejection port 502 is located at the bottom of the ejection chamber 501. The projectile 700 falls under gravity from the ejection port 502 into the transfer device 400.
