[0041] A buffer plate 6 is fixedly connected to the bottom of the magazine 4, and the buffer plate 6 is made of rubber.

[0042] A partition plate 8 is provided on the side of the contour gear 5 , and the partition plate 8 is fixedly connected to the loading rack 2 . The partition plate 8 is used to disconnect the ammunition belt 10 from the contour gear 5 .

[0043] As attached Figure 3-5 As shown, the transmission mechanism 3 includes a motor 31, a gear box 32, a bevel gear 1 321, a bevel gear 2 322, a connecting shaft 323, a bevel gear 324, a bevel gear 4 325, a transmission shaft 326, a main shaft 33, a transmission sheave 331, a rotating pin 332, and a limit sheave 34;

[0044] Bevel gear 1 321, bevel gear 2 322, connecting shaft 323, bevel gear 3 324, bevel gear 4 325 and transmission shaft 326 are all installed inside the gear box 32, bevel gear 1 321 is connected to the output shaft of the motor 31, bevel gear 1 321 is meshed and connected with bevel gear 2 322, connecting shaft 323 is fixedly connected with the bevel gear, bevel gear 4 325 is fixedly connected to the outer wall of connecting shaft 323, and the axis of bevel gear 4 325 coincides with the axis of bevel gear 2 322, bevel gear 3 324 is meshed and connected with bevel gear 4 325, bevel gear 3 324 is fixedly connected with transmission shaft 326, transmission shaft 326 and connecting shaft 323 are perpendicular to each other, and transmission shaft 326 passes through the outside of the gear box 32;

[0045] The main shaft 33 is rotatably connected to the inner side of the loading rack 2, and the main shaft 33 is fixedly connected to the contour gear 5. The inner side of the main shaft 33 is fixedly connected to a transmission groove wheel 331, and the outer side of the transmission groove wheel 331 is movably connected to a rotation pin 332, and the rotation pin 332 is fixedly connected to the outer end of the transmission shaft 326;

[0046] The limiting groove wheel 34 is rotatably connected to the outer wall of the magazine 4, and the teeth of the limiting groove wheel 34 are engaged with the bullet.

[0047] Working principle: the motor 31 drives the bevel gear 2 322 connected to the bevel gear 1 321 to rotate, and then drives the connecting shaft 323 to rotate. The connecting shaft 323 drives the bevel gear 3 324 to rotate through the bevel gear 4 325. The bevel gear 3 324 drives the transmission shaft 326 to rotate. The transmission shaft 326 drives the rotating pin 332 to rotate. The rotating pin 332 drives the transmission groove wheel 331 and the contour gear 5 to rotate intermittently, thereby driving the bullet chain 10 to move through the contour gear 5. At the same time, the connecting shaft 323 drives the rotating block 72 to rotate. The rotating block 72 drives the crank 71 to move through the pin shaft 1 and the through groove 1. The crank 71 drives the push block 74 to move through the through groove 2 and the pin shaft 2. The push block 74 pushes the bullet out, so that the bullet is inserted into the bullet chain 10. The push block 74 prevents the uninstalled bullet from being inserted into the bullet chain 10. The bullet slides down, and then the crank 71 continues to rotate to reset the push block 74. The bullet falls to the top of the buffer plate 6 under the action of gravity. At the same time, the contour gear 5 rotates to the next gear tooth and stops. The push block 74 pushes the new bullet to insert the bullet chain 10. By repeating the above work, multiple bullets are automatically installed on the bullet chain 10. The buffer plate 6 prevents the bullets from being damaged when they fall. The installed part of the bullet chain 10 continues to move with the contour gear 5, and the limit groove wheel 34 prevents the bullet chain 10 from tilting up. At the same time, the limit groove wheel 34 rotates with the movement of the bullet chain 10, and the bullet chain 10 is separated from the contour gear 5 by the partition plate 8, so that the part of the bullet chain 10 that has been loaded can be removed, so that automatic loading can be carried out without the need for special loading personnel, thereby reducing the logistical burden and facilitating use.

[0048] The above embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
