The magazine return sprocket shaft system 3 passes through through-hole 1-1.3 and through-hole 5 1-3.4 and is installed between the front and rear vertical plates 1-1 and 1-3. A continuous, U-shaped, annular track groove is provided on the inner sides of both the front and rear vertical plates 1-1 and 1-3. The two U-shaped openings of the track face each other and align at all points. The arc section on the other side of the magazine return sprocket shaft system serves as an eccentric track. The front and rear storage units 2 are connected in series via storage unit pin 1 2-2 and storage unit pin 2 2-5, respectively, forming a circular arrangement within the magazine track. A through-hole 6 1-3.6 is provided on the rear vertical plate 1-3, coaxially with through-hole 2 1-1.6, serving the same function as through-hole 2 1-1.7. The rear support base 1-5 is fixed to both sides of the trapezoidal shape on the outer side of the rear vertical plate 1-3.The front support seat 1-4 is parallel to the bottom of the rear support seat 1-5 and is installed on the launcher pitch bracket. The inner track of the front vertical plate 1-1 is provided with a notch at the position opposite to the bullet outlet 1-1.2 and the bullet replenishment port 1-1.1.

[0037] The ammunition storage unit 2 comprises an ammunition storage barrel 2-3, an ammunition deflector plate 2-1, an ammunition deflector plate return spring 2-4, an ammunition storage unit pin 1 2-2, an ammunition storage unit roller 1 2-6, an ammunition storage unit pin 2-5, an ammunition storage unit roller 2-7, and an ammunition storage unit caster 2-8. The ammunition storage barrel 2-3 is a semi-enclosed cylindrical structure with brackets at both ends. Four through-holes are symmetrically positioned on either side of the brackets, aligned front and back. The semi-enclosed end of the ammunition storage barrel is designated the rear, while the other end is designated the front. The magazine unit pin shaft 1 2-2 and the magazine unit pin shaft 2 2-5 respectively pass through the front through hole and the rear through hole of the magazine unit 2-3 to hinge the two magazine units 2 together. Finally, when the two magazine units 2 are connected, the magazine unit pin shaft 1 2-2 and the magazine unit pin shaft 2 2-5 respectively pass through the through hole 2 1-1.6 and the through hole 6 1-3.6, and pass through the front through hole and the rear through hole of the magazine unit 2-3, so that the magazine units can be arranged in a ring shape in the track more simply, reducing the difficulty of assembly. A bullet storage unit roller 2-6 is provided at the end of the bullet storage unit pin shaft 2-2 away from the bullet storage barrel 2-3, and a slot is provided at the end of the bullet storage unit pin shaft 2-5 away from the bullet storage barrel 2-3, with a through hole at each end of the slot. A cylindrical pin passes through the two through holes to confine the bullet storage unit caster 2-8 in the slot, and a bullet storage unit roller 2-7 is provided at the end of the bullet storage unit pin shaft 2-5 with the slot. A lug is provided at the front of the bullet storage barrel 2-3, and a bullet blocking plate 2-1 is hinged on the lug. The bullet blocking plate reset torsion spring 2-4 drives the bullet blocking plate 2-1 to rotate in the closing direction. The bullet deflector 2-1 is equipped with a contact post 2-1.1 facing the front upright 1-1. The bullet deflector block 1-1.3 does not rotate. Instead, it features an inclined surface. When each storage unit 2 rotates along the track in a certain direction, this inclined surface contacts the contact post 2-1.1 of the bullet deflector 2-1, causing the bullet deflector 2-1 to rotate open. A stopper 2-3.1 is located within the semi-enclosed end of the ammunition storage barrel 2-3 to secure the special ammunition within the barrel 2-3. The stopper 2-3.1 engages a groove in the base of the special ammunition, ensuring that the special ammunition remains in the same direction as the ammunition storage unit 2 as it moves. This ensures that the lifting side of the projectile faces upward during loading, meeting loading requirements. The axes of the first and second rollers 2-6 and 2-7 of the ammunition storage unit are parallel to the axis of the ammunition storage barrel 2-3, while the axis of the caster 2-8 of the ammunition storage unit is perpendicular to the axis of the ammunition storage barrel 2-3. The caster 2-8 of the ammunition storage unit is arranged inside the second roller 2-7 of the ammunition storage unit, and its rotating surface slightly protrudes from the end surface of the second roller 2-7 to contact the annular track groove.

The magazine rotating shaft 3-1 is connected to the magazine sprockets 3-2 at both ends. The two magazine bearings 3-3 are respectively sleeved on one side of the two magazine sprockets 3-2 and are respectively installed at the through hole 1-1.5 of the front vertical plate 1-1 and the through hole 3 1-3.4 of the rear vertical plate 1-3. The gear part of the magazine sprocket 3-2 extends into the inner side of the "U"-shaped groove of the magazine track.

[0039] The magazine drive assembly 4 comprises a magazine drive housing 4-3, a magazine speed reducer 4-2, a magazine encoder assembly 4-1, and a magazine drive motor 4-4. The magazine drive housing 4-3 is secured to the mounting hole 61-3.5 on the rear vertical plate 1-3. The magazine speed reducer 4-2 and the magazine encoder assembly 4-1 are both mounted on the magazine drive housing 4-3. The magazine rotary shaft 3-1 passes directly through the drive housing 4-3. The magazine speed reducer 4-2 and the magazine encoder assembly 4-1 are connected via a coupling. The magazine drive motor 4-4 is mounted on the input end of the magazine speed reducer 4-2. When the magazine drive assembly 4 drives the magazine, the magazine sprocket 3-2 directly engages with the magazine unit pin 1 2-2 and the magazine unit pin 2 2-5, driving the magazine unit. The continuous circular track ensures smooth movement of the magazine unit.

[0040] The feeder body 5 comprises a feeder housing 5-1, a feed chain 5-2, a curved chain box 5-3, and a chain initial position switch 5-4. One end of the curved chain box 5-3 is mounted on the feeder housing 5-1, aligned with the chain inlet. The other end is connected to the straight chain box 1-8, aligned with the rectangular through-hole 1-3.1. The feed chain 5-2 is wound around a sprocket and housed within the feeder housing 5-1, the curved chain box 5-3, and the straight chain box 1-8. The chain initial position switch 5-4 is mounted on the feeder housing 5-1.

[0041] The feeder drive assembly 6 includes a feeder reducer 6-1 and a feeder drive motor 6-2. The feeder reducer 6-1 is mounted on one side of the feeder housing 5-1, with its output shaft directly inserted into the sprocket of the feeder housing 5-1. The feeder drive motor 6-2 is mounted on the feeder reducer 6-1.

[0042] Furthermore, the magazine bearing 3-3 is a deep groove ball bearing or an angular contact ball bearing.

[0043] Furthermore, the magazine reducer 4-3 is a worm gear reducer, and the feeder reducer 6-1 is a planetary gear reducer;

[0044] The assembly process of the compact horizontal supply system for special ammunition of the present invention is as follows:

[0045] Installation of the magazine. First, connect the front support base 1-4 and the rear support base 1-5 to the front vertical plate 1-1 and the rear vertical plate 1-3. Simultaneously, install the bullet deflector block 1-1.3 and the bullet-passing plate 1-1.4 to the front vertical plate 1-1. Then, connect the assembled front vertical plate 1-1 and the rear vertical plate 1-3 via the tie rod 1-2 and the linear chain box 1-8 to form a whole. During the connection process, pass the magazine return sprocket shaft system 3 through the through hole 1-1.5 and the through hole 5 1-3.4 and install it between the front vertical plate 1-1 and the rear vertical plate 1-3. Several magazine units 2 arranged in a chain are fed into the track through the track gaps 1-1.8. When two magazine units 2 are finally connected, magazine unit pins 1-2 and 2-5 pass through through-holes 2-1.6 and 6-1-3.6, respectively, and through the front and rear through-holes of magazine unit 2-3, ultimately forming a circular arrangement within the track. Finally, the magazine drive assembly 4 is installed at the rear of the magazine section, completing the magazine assembly.

[0046] Install the ramming mechanism. After the magazine is installed, feed a portion of the ramming chain through the rectangular through-hole 1-3.2 and into the linear chain box 1-8. Simultaneously, install the ramming mechanism housing 5-1 on the rear vertical plate 1-3 through the mounting hole 5 1-3.3. Install the ramming chain initial position switch 5-4 on the ramming mechanism housing 5-1. Finally, install the ramming mechanism drive assembly 6 on one side of the ramming mechanism housing 5-1, completing the ramming mechanism installation.

[0047] The working process of the compact horizontal supply system for special ammunition of the present invention is as follows:

[0048] The present invention has a feeding mode and a replenishing mode. The working processes in these two modes are described below:

[0049] Feed mode. The magazine drive motor 4-4, through the magazine reducer 4-2, drives the magazine sprocket shaft 3 to rotate. The magazine rotates toward the direction where the deflector plate shifter 1-1.3 can open the deflector plate 2-1 to select rounds. The selected storage unit 2 rotates to the discharge port 1-1.2. The deflector plate shifter 1-1.3 contacts the contact pin 2-1.1 of the deflector plate 2-1, causing the deflector plate 2-1 to rotate and open. The feed drive motor 6-2, through the feeder reducer 6-1, drives the sprocket to advance the feed chain 5-2. The feed chain 5-2 passes through the convex hole in the rear vertical plate 1-3 and extends into the selected storage unit 2, pushing the projectiles out of the storage unit. The projectiles enter the launcher through the discharge port 1-1.2 of the front vertical plate 1-1. After the projectile is ejected, the feed drive motor reverses, pulling the feed chain 5-2 back to its original position. The magazine completes a feed. The magazine can continue to rotate to the next bullet position to continue feeding bullets. After the previous bullet storage unit 2 rotates over the bullet blocking plate block 1-1.3, the bullet blocking plate 2-1 automatically resets.

[0050] Reloading mode. Manually rotate contact pin 2-1.1 of bullet deflector 2-1, causing it to swing open and feed the projectile into storage unit 2, ensuring that the notch at the bottom of the projectile fully contacts the stop block 2-3.1 inside the storage unit. Release contact pin 2-1.1, causing bullet deflector 2-1 to return to its original position under the action of bullet deflector return spring 2-4, completing the reloading process. The magazine can then continue rotating to the next position for further reloading.
