Description

Technical Field

[0001] The present invention relates to artillery maintenance and support equipment, in particular to an impact-type bullet ejection mechanism for artillery. Background Art

[0002] Currently, split-load projectiles remain an important component of weapons and ammunition. Their variable charge and portable packaging have long been popular, and they are widely used in tank guns, ground artillery, and other weapons and equipment. When live-fire exercises require a halt due to unexpected equipment failures, sudden changes in weather conditions such as rain, snow, and hail, or position relocation, the remaining projectiles must be ejected.

[0003] Due to the nature of the use of split-load projectiles, the typical procedure for extracting a projectile is as follows: after ejecting the cartridge, the gun barrel is flattened, a simple ejector is screwed onto the front end of the flushing rod and inserted into the muzzle. This impacts the projectile's head, dislodging the projectile's band from the rifling, ultimately releasing the projectile and allowing it to exit the barrel. However, this requires the combined efforts of multiple personnel to provide the necessary force, which is labor-intensive and time-consuming. Summary of the Invention

[0049] The present embodiment is an impact-type ejection mechanism for artillery. When assembling the impact-type ejection unit, the pulley is first placed inside the limiting portion 122 and located at the first mounting hole 1222. The rotating ring is then inserted into the limiting portion from the rear end so that the threaded hole of the rotating ring corresponds to the shaft hole of the pulley. The locking bolt is then inserted from the outside of the limiting portion 122 through the first mounting hole 1222, and the rotary transmission assembly 13 is then installed on the impact assembly 12. It should be noted that the locking bolt is set as an optical axis portion at a position corresponding to the pulley shaft hole and is set as an external threaded portion at a position corresponding to the threaded hole of the rotating ring. Then, the impact assembly 12 assembled with the rotary transmission assembly 13 is inserted into the connecting cylinder 11 from front to back through the first keyway 1212 and the first connecting key 1111, and the push is continued to make the transmission connection part 132 of the rotary transmission assembly 13 pass through the connecting ring plate 1121 of the inner cylinder body, and the gasket 134 is installed from the rear end of the connecting cylinder 11 to the transmission connection part 132. Then, the pin 135 is passed through the third mounting hole 1113 of the outer cylinder body 111 and the second mounting hole 1122 of the inner cylinder body 112 in turn, and then inserted into the pin hole of the transmission connection part 132, thereby completing the assembly of the impact type bullet-removing unit 1. Furthermore, after assembling the rotating power unit 2, the braking unit 3 and the walking unit 4, the second key slot 221 of the rotating cylinder 22 of the impact type ejection unit is correspondingly inserted into the second connecting key 1321 of the impact type ejection unit 1. Then, the connecting cylinder of the impact type ejection unit is slightly rotated so that the connecting head 114 is correspondingly engaged with the connecting slot 212, thereby completing the assembly of the entire impact type ejection mechanism.

[0050] The embodiment of the present invention is a percussion ejection mechanism for artillery. When in use, the entire percussion ejection mechanism is inserted from the muzzle of the gun chamber 6, and the motor M3 is started to move the entire mechanism forward along the gun chamber (e.g., Figure 18 The first state shown); at this time (as Figure 11 As shown), the slider portion of the rotary transmission assembly is located exactly at the rear end of the release track (as shown Figure 7 L, L' shown); when the whole mechanism moves to the position where the front end of the impact-type ejection unit and the projectile 5 in the barrel 6 are located, the conical mouth of the impact portion of the impact assembly of the impact-type ejection unit contacts the head of the projectile, and the whole mechanism continues to move forward. The projectile presses the impact assembly, so that the impact assembly remains stationary relative to the projectile during the process of the whole mechanism continuing to move forward (i.e., the impact assembly moves backward relative to the connecting tube), and the spring is compressed; when the micro switch moves forward with the whole mechanism and disengages from the impact assembly, the switching state of the micro switch changes, and a signal that the projectile is in place is fed back. At this time, the motor M2 of the brake unit is activated, and the brake block is driven to extend outward, contact and press the inner wall of the barrel, and the motor M3 of the travel unit stops moving; in this state (as shown Figure 19As shown), the slider portion of the rotary transmission assembly is located exactly in the connecting area between the rear end of the limiting track (arc track) and the release track (straight track) (as shown). Figure 7 Then, the motor M1 of the rotary power unit rotates, driving the rotary transmission assembly to rotate. Under the cooperation between the slider and the track, and under the guidance of the first connecting key and the first keyway, the impact assembly is driven to move backward relative to the connecting cylinder, and the spring is further compressed until the front end position of the track is released (as shown in FIG. Figure 7 N, N' shown) corresponds to the slider portion (as shown Figure 20 As shown), at this time, under the action of the spring, the impact assembly is rapidly pushed forward, so that the impact part impacts the head of the projectile; and the slider part returns to the connection between the rear end of the limiting track (arc track) and the release track (straight track), that is, completing an impact cycle. Under the continuous rotation of the motor M1, the head of the projectile is continuously impacted until the projectile is loosened and moves backward. After the projectile moves backward, the impact assembly is no longer restricted by the projectile, and then presses the micro switch, so that the switching state of the micro switch changes again, and the signal of the projectile exit is fed back. At this time, the motor M1 stops rotating, the brake unit motor M2 reverses, the brake block disengages from the inner wall of the barrel, the motor M3 reverses, and the whole structure moves backward along the barrel and exits the barrel, completing the ejection operation.

[0051] The above embodiments should not limit the present invention in any way, and any technical solutions obtained by equivalent replacement or equivalent conversion fall within the protection scope of the present invention.
