DETAILED DESCRIPTION

[0037] In order to make the purpose, technical scheme and advantages of the utility model clearer, the technical scheme of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope protected by the utility model.

[0038] Reference Figures 1-4 The specific embodiment of the utility model provides a bullet pressing machine, which comprises a first box body 2 and a feeding hopper 4, the feeding hopper 4 is clamped at the top of the first box body 2, and further comprises:

[0039] An electric control box 1 is clamped on one side of the first box body 2.

[0040] A bullet pressing unit is installed in the first box body 2 and is driven by the electric control box 1.

[0041] A chain wheel set 6 is rotatably connected to the first box body 2 and is in transmission connection with the bullet pressing unit, and the bullets at the bottom of the feeding hopper 4 are pressed into the belt link on the chain wheel set 6 by the bullet pressing unit.

[0042] The bullet pressing machine is a loading device of modern artillery to replace the physical burden and time delay of manual loading of cannonballs. Usually, the bullet pressing machine itself can store a certain number of cannonballs, and then manually load after shooting. For the existing 12.7mm bullet and belt, the existing bullet loading device used by the army is mostly a hand-operated mechanical device, which is time-consuming and laborious to load manually, and the overall structure is inconvenient to carry. In the application, the electric control box 1 is clamped on the first box body 2, that is, it can be detachably connected, which is relatively flexible in transportation and assembly. A plurality of bullets are orderly placed in the feeding hopper 4, the bullet pressing unit is driven by the electric control box 1, the bullets at the bottom of the feeding hopper 4 are pushed into the belt link on the chain wheel set 6, with the action of the bullet pressing unit, the chain wheel set 6 is synchronously driven to rotate by a certain angle, and the bullets are continuously pushed into the belt link. At the same time, in special cases, the electric control box 1 can also be quickly removed, and the bullet pressing unit is manually driven, that is, the bullets are loaded by a traditional hand-operated mechanical device. Overall, the application realizes the automatic bullet loading function, is portable, can be carried detachably, has small size, can be compatible with manual operation, and considers various use environments.

[0043] Further optimization scheme further comprises:

[0044] An intermittent wheel assembly is installed in the first box body 2, and the chain wheel set 6 is in transmission connection with the bullet pressing unit through the intermittent wheel assembly.

[0045] The intermittent wheel assembly allows one bullet to be pushed into the ammunition belt at a time, which is then rotated by the sprocket group 6 at a certain angle, facilitating the loading unit to continue pushing in the next bullet and ensuring the continuity of the loading process.

[0046] The optimized design includes the following spring compression unit:

[0047] Gearbox 8 is installed at the bottom inside the first housing 2 and is connected in transmission between the motor and the intermittent wheel assembly inside the electrical control box 1.

[0048] The pressing block 17 is slidably connected in the groove 16 on the top of the inner side of the first box 2 along the direction close to or away from the discharge hopper 4. The pressing block 17 is connected to the gear box 8 through the swing arm assembly.

[0049] The output shaft of the motor extends into the gearbox 8 and is connected to the gearbox 8 for transmission. After the motor starts, it drives the swing arm assembly through the gearbox 8 to push the pressing block 17, pushing the bullets at the bottom of the discharge hopper 4 into the bullet chain. The swing arm assembly enables the pressing block 17 to slide back and forth in the groove 16 in the direction of approaching or moving away from the discharge hopper 4, ensuring the continuity of the pressing process. Whenever the pressing block 17 pushes a bullet again, the motor drives the intermittent wheel assembly, causing the feed chain wheel group 6 to rotate the bullet chain by a certain angle, pushing the bullet into the next empty position on the bullet chain.

[0050] Further optimization of the design includes the following swing arm components:

[0051] The rocker arm cam 9 is fixedly sleeved on the first output shaft of the gear box 8;

The second end of the second swing arm 15 is movably connected to the pressure block 17, and the second swing arm 15 drives the pressure block 17 to slide in the slide groove 16.

[0054] The motor drives the first output shaft of the gearbox 8 to rotate, which in turn drives the rocker arm cam 9 to rotate and simultaneously drives the first rocker arm 10 and the second rocker arm 15 to swing. During the swinging process, the pressing block 17 reciprocates within the slide groove 16. Specifically, when the rotation centers of the first output shaft of the gearbox 8 and the rocker arm cam 9 are located between the two ends of the first rocker arm 10 and are collinear, the pressing block 17 moves away from the discharge hopper 4. When the rotation center of the rocker arm cam 9 moves away from the second end of the first rocker arm 10, as... Figure 3 As shown, the press block 17 approaches the discharge hopper 4 and pushes out a bullet.

[0055] Further optimization scheme, the swing arm assembly further comprises:

[0056] The oblong hole 19 is arranged on the second end of the second swing arm 15.

[0057] The protrusion 18 is fixedly connected to the side wall of the bullet pressing block 17 and is slidingly connected in the oblong hole 19.

[0058] In order to ensure that the bullet pressing block 17 slides linearly in the sliding groove 16, the protrusion 18 slides in the oblong hole 19 and pushes the bullet pressing block 17 to move during the swinging of the second swing arm 15.

[0059] Further optimization scheme, the intermittent wheel assembly comprises:

[0060] The intermittent cam 20 is fixedly sleeved on the second output shaft 14 of the gear box 8.

[0062] The second output shaft 14 and the intermittent cam 20 rotate synchronously, and the intermittent cam 20 drives the intermittent synchronous wheel 21 to rotate by a certain angle and synchronously drives the feed sprocket set 6 to rotate by a certain angle every time the intermittent cam 20 rotates one revolution, thereby realizing the continuous movement of the belt during the bullet loading process; wherein the intermittent synchronous wheel 21 and the feed sprocket set 6 are drivingly connected through gear meshing, and the above-mentioned gear meshing transmission is a conventional technology which will not be described and illustrated in detail here.

[0063] Further optimization scheme, further comprising:

[0064] The sliding seat 11 is vertically slidingly connected to the side wall of the gear box 8 through a sliding column (not marked in the figure) and abuts against a spring (not shown in the figure) between the outer side wall of the gear box 8, and the sliding end (i.e. the sliding column) of the sliding seat 11 is connected to the bullet loading counter 3 on the first box body 2 through the counter tension spring 12.

[0065] The counting cam 13 is fixedly sleeved on the second output shaft 14 and located above the sliding seat 11.

[0066] The second output shaft 14 is fixedly connected to the counting cam 13, and every time the second output shaft 14 rotates one revolution, the counting cam 13 presses the sliding seat 11 once, and the sliding seat 11 moves upward by the elastic force of the spring after each downward movement; when the sliding seat 11 moves downward each time, the counting contact of the bullet loading counter 3 is pulled by the counter tension spring 12, and the counting is performed once, which means that a bullet is pressed in.

[0067] Further optimization scheme, further comprising:

[0068] The battery 7 is installed in the electric control box 1 and electrically connected with the motor and the loading counting device 3.

[0069] The battery 7 can be prepared in several groups to ensure the endurance of the bullet press.
