Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an ammunition delivery method from a bullet feeder to a loading portion of a cannon in a revolver type cannon.
[0002]
[Prior art]
Revolver-type cannons rotate the chamber chamber drums, which have multiple chambers arranged at equal intervals on the same circumference, to sequentially rotate the ammunition supplied from the ammunition machine to the chamber chamber loading section. The chamber is pushed into the chamber, and the bullet chamber is fired by firing the ammunition in the chamber while the chamber, which has been pushed in, is stopped according to the position of the gun barrel arranged in front of the chamber drum. Conventionally, in this type of machine gun, the ammunition in the ammunition machine is always pressed against the loading part by an external force separate from the driving force of the chamber drum, and the ammunition is pushed in as the loading part rotates. Has been adopted. The reason why the ammunition is pushed in by external force is that the feeder is generally fixed and the loading part moves back and forth back and forth by shooting, so it is not related to the rotational driving force of the loading part. There is a convenient way to push the ammunition with the power of.
[0003]
[Problems to be solved by the invention]
Thus, such a conventional revolver type cannon has the following technical problems. That is, the force for pushing the ammunition into the loading portion is set so as to be able to obtain the maximum firing speed so as not to be affected by the magnitude of the cannon firing speed. For this reason, when ammunition is sent from the ammunition machine to the loading unit, it is gradually accelerated to reach a high speed, and then collides with the loading unit to stop, increasing the impact. This is because the speed during ammunition feeding is not controlled and the ammunition is stopped by the collision phenomenon, and the impact force is a magnitude that cannot be ignored even when the firing speed is low.
[0004]
For this reason, the conventional ammunition gives a structure and strength that resists this impact force and does not deform, and there is a technical problem that it is necessarily large and heavy. In addition, it is necessary to increase the strength of the bullet feeding section itself from the bullet feeder to the loading section.
Furthermore, due to the large and heavy ammunition, not only the ammunition storage space is increased, but also the technical problem that the power required to transfer and load ammunition is large and the cannon is enlarged. is there.
[0005]
[Means for Solving the Problems]
The present invention has been made in view of such a conventional technical problem, and the configuration thereof is as follows.
In the first aspect of the present invention, the chamber drum 2 is rotatably supported by a gun rack 41 having a barrel 30 and is rotated on the same circumference by the intermittent drive mechanism 6. A plurality of chambers 25 are formed in the chamber 25, and the ammunition 24 supplied to the loading unit 3 of the chamber chamber drum 2 from the ammunition machine 9 that does not perform the rear seat and back seat movements is intermittently moved to the chamber 25 that rotates and moves intermittently. A revolver that shoots after being loaded by the mechanism 44, and that the gun rack 41 is rear seated and returned by the seating / returning seat mechanism 40 and pushes the cartridge case 24 "remaining in the chamber 25 out of the chamber 25. Ammunition delivery method of type cannon,
A first gear 4 that is provided on the outer periphery of the chamber drum 2 and is intermittently rotationally driven by the intermittent drive mechanism 6, and a bullet feeding claw of the bullet feeder 9 that feeds the ammunition 24 to the loading unit 3. The second gear 5 that rotates integrally with the vehicle 17 is meshed with a width that is always engaged from the time when the gun mount 41 is seated backward to the time when it is rear seated, and the rotational driving force of the intermittent drive mechanism 6 is fed. The ammunition delivery method of the revolver type cannon is characterized in that the ammunition 24 held in the bullet feeding claw wheel 17 is fed to the loading portion 3 of the chamber chamber drum 2.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
1 to 4 show an embodiment of a revolver type cannon including an ammunition delivery device according to the present invention. In FIG. 4, reference numeral 1 indicates a fixing member (for example, a cradle) that does not perform the rear seat and reverse seat movements, and a gun mount 41 is attached on the fixing member 1 via a parking and returning seat mechanism 40. Yes. On the gun rack 41, the chamber drum 2 is rotatably supported, and one gun barrel 30 is fixed to the lower front end. A closing part 41 a is formed in the middle part of the gun rack 41. The closing portion 41a closes the rear surface of the lower chamber 25g shown in FIG. The closing part 41a is provided with an ignition device (not shown) for firing. In addition, a bullet feeder 9 is fixed to the fixing member 1 adjacent to the chamber chamber drum 2, and consumed ammunition 24 is replenished one after another toward the chamber chamber drum 2.
[0007]
The chamber chamber drum 2 is formed with a plurality (eight in this example) of chamber chambers 25a to 25h having a circular cross section on the outer peripheral portion of the cylindrical portion 2a at the front thereof. Each chamber 25 is formed at equal intervals so that the barrel 30 and the central axis are parallel. In the chamber 25g at a predetermined position (lower end) in FIG. 2, the gun barrel 30 shown in FIG. Accordingly, the chamber drum 2 is driven by an intermittent drive mechanism 6 which will be described later and rotates intermittently, and the chambers 25 come to the positions of the chambers 25g at the lower end portion, so that the gun barrel 30 and the central axis are aligned. Match.
[0008]
On the rear side of the cylindrical portion 2a of the chamber drum 2, a loading portion 3 for the ammunition 24 and the first gear 4 are sequentially formed, and the loading portion 3 is held outside between the pair of formed loading portions 3. A guide 10 is provided for guiding the ammunition 24 by a semicircular inner peripheral surface. The guide 10 is fixed to the bullet feeder 9. Further, behind the cylindrical portion 2 a of the chamber drum 2, a rammer mechanism 44 for sending the ammunition 24 held in the loading unit 3 into the chamber 25 is attached.
[0009]
Accordingly, the ammunition 24 fed from the bullet feeder 9 to the loading unit 3 through the bullet feed hole 47 shown in FIG. 2 is sent into the predetermined medicine chamber 25 by the ramper mechanism 44. Reference numeral 10 a denotes a guide surface that guides the ammunition 24 fed from the bullet feeder 9 to the loading unit 3, and is formed on the guide 10. At the location corresponding to the bullet feed hole 47, the runner 44a of the runner mechanism 44 takes the most retracted position as shown in FIG. 1, and the ammunition 24 is fed one after another in front of the runner 44a taking this position. The rammer mechanism 44 moves the rammer 44a forward and backward in conjunction with the intermittent movement of the chamber drum 2, and the ammunition 24 supplied to the front of the rammer mechanism 44 is shot at the lower end position where the gunshot is performed, that is, the shooting is performed. Before reaching the chamber 25g, it may be pushed into the chamber 25 and loaded, and may have a function of retreating to a position where it does not interfere with the closed portion 41a of the gun rack 41 during shooting. If the ammunition 24 held in the chamber 25 reaches the chamber 25g at the lower end and is fired and a bullet is fired, the chamber drum 2 moves backward while receiving the function of the parking / returning seat mechanism 40. Then, move forward again.
[0010]
The chamber drum 2 is driven by an intermittent drive mechanism 6 including a motor 46 and rotates intermittently. In the illustrated example, since eight chambers 25a to 25h are provided, one step consists of 45 ° rotation of the chamber drum 2 and stops after the rotation. The time of step consisting of rotation and stop, that is, the firing speed, is adjusted by increasing or decreasing the speed of the motor 46 of the intermittent drive mechanism 6. The chamber chamber drum 2 is controlled by the intermittent drive mechanism 6 so as to perform acceleration and deceleration motions with less impact during one step rotation. In other words, the intermittent rotation of the chamber drum 2 by the intermittent drive mechanism 6 is slow at both the start and end of the intermittent rotation and the intermediate rotational speed is fast in order to reduce the impact according to the firing speed. It is set to be.
[0011]
The bullet feeder 9 has a bullet feeder main body 11 in which bullet feed holes 47 are formed as shown in FIGS. The bullet feeder main body 11 includes a frame portion 11a that is formed in a rectangular tube shape and is open at the front and rear, a front frame portion 11b that is disposed so as to cover a front opening surface of the frame portion 11a, and a rear opening surface of the frame portion 11a. And a rear frame portion 11c arranged to cover. A support member 11d connected to the front and rear frame portions 11b and 11c at appropriate positions is disposed inside the frame portion 11a.
[0012]
A shaft 19 is rotatably supported (or non-rotatable) on an upper portion of the support member 11d, and a pair of chain wheels 12 and 13 are rotatably supported on both front and rear ends of the shaft 19. A shaft 21 is rotatably supported at the lower portion of the support member 11d, and a pair of chain wheels 14 and 15 are fixed to both front and rear ends of the shaft 21. Endless annular chains 7 and 8 are wound around the chain wheels 12, 14 and 13, 15 which are paired up and down, respectively. A rotation drive source 22 is attached to the rear frame portion 11 c so that the chain wheels 14 and 15 can be driven via the shaft 21.
[0013]
Further, a shaft 20 is rotatably supported at an intermediate portion in the vertical direction of the support member 11d, a second gear 5 is fixed to a rear end portion of the shaft 20, and a bullet feeding claw wheel is disposed at the center portion of the shaft 20. 17 is fixed. As shown in FIG. 1, the second gear 5 is located in the gap between the frame portion 11 a and the rear frame portion 11 c, and the outer peripheral tooth portion slightly protrudes from the frame portion 11 a and is provided on the outer periphery of the chamber drum 2. The first gear 4 is engaged. The first gear 4 is given a width that always meshes with the second gear 5, and of course, when the gun rack 41, the chamber drum 2, and the gun barrel 30 are moved forward by the function of the parking and returning seat mechanism 40, the first gear 4 is moved backward. Sometimes it has a width that does not disengage from the second gear 5. In other words, the first gear 4 that is intermittently rotated by the intermittent drive mechanism 6 and the second gear 5 that rotates integrally with the bullet feeding claw wheel 17 that feeds the ammunition 24 to the loading unit 3 include the machine gun. The gun mount 41 is meshed with a width in the front-rear direction that is always engaged from the time of returning to the time of rear seating.
[0014]
The number of teeth of both gears 4 and 5 is set such that both the chamber drum 2 and the bullet feeding wheel 17 rotate one step at a time. That is, in this example, eight chambers 25 are formed in the chamber drum 2, and the bullet feeding claw wheel 17 has four claw portions. Accordingly, it is necessary to feed the ammunition 24 from the bullet feeder 9 to the loading unit 3 by rotating the bullet feeding claw wheel 90 by 90 ° while the chamber drum 2 rotates by 45 °. For this reason, the ratio of the number of teeth of the first gear 4 and the second gear 5 is 2: 1, and the first gear 4 and the second gear 5 rotate in the opposite direction. For this reason, when an idle gear is interposed between the first gear 4 and the second gear 5, an even number of idle gears is used.
[0015]
An ammunition sprocket 16 is rotatably supported at the center of the shaft 19, and an ammunition sprocket 18 is rotatably supported at the center of the shaft 21. The sprockets 16 and 18 for ammunition have a shape that can hold the ammunition 24 and have a claw wheel shape. Further, a push bar 23 is connected to the chains 7 and 8 in parallel with the shafts 19, 20 and 21. The push bar 23 is arranged so that it can pass through the chain wheels 12, 13, 14, 15 without hindrance and the ammunition sprockets 16, 18 can pass through without hindrance. FIG. 2 shows a state in which the ammunition 24c is stopped by hitting the bullet feeding claw wheel 17. The ammunition 24 a indicates after delivery to the loading unit 3, and the ammunition 24 b indicates what is being delivered to the loading unit 3.
[0016]
Thus, an annular ammunition supply path 11e is defined around the support member 11d inside the frame portion 11a. The ammunition 24 is continuously arranged while being supplied and stacked in the ammunition supply path 11e in the ammunition body 11 from the opening 11f shown in FIG. 2, and a part of the ammunition 24 is attached to the sprockets 16 and 18 for ammunition. Is retained. When the shaft 21 and the chain wheels 14 and 15 are rotationally driven by the rotational drive source 22, the chain wheels 12 and 13 are rotationally driven through the chains 7 and 8, and the push bar 23 is moved. By the movement of the push bar 23, the ammunition 24 in the ammunition supply path 11e is pushed, and the ammunition 24c hits the bullet feeding claw wheel 17 and stops. Therefore, the rotation drive source 22 has a function as a spring motor, and always urges the rotation of the shaft 21 by the spring.
[0017]
Thus, the ammunition 24 in the ammunition supply path 11e is pushed by the push bar 23 and moves. For this reason, the sprockets 16 and 18 for ammunition need only guide the folding of the ammunition 24 at the upper and lower ends of the ammunition supply path 11e, and do not need to be driven to rotate to supply the ammunition 24. Accordingly, the ammunition sprocket 16 only needs to be supported on the shaft 19 so as to be rotatable relative to the chain wheels 12 and 13 so that the ammunition 24 pushed in for replenishment can pass therethrough. The shaft 19 may be supported so as to be rotatable with respect to the support member 11d. In addition, the ammunition sprocket 18 is rotationally driven during the return movement of the push bar 23 to prevent the ammunition 24 from flowing backward, and to allow passage of the ammunition 24 pushed in for replenishment. The shaft 21 is rotatably supported without being fixed.
[0018]
A specific example of the ramper mechanism 44 will be described with reference to FIGS. The ramper mechanism 44 is configured to drive the ramper 44 a by the cam drum 43. The cam drum 43 is fixed to the gun rack 41 in a cantilevered state with the cam drum 43 inserted into the chamber drum 2 from the front (left side in FIG. 5). The chamber chamber drum 2 is rotatably supported by the cam drum 43 at the front end portion at the bearing 27 and at the rear end portion at the bearing 28, and further, the rear end portion rotates at the gun mount 41 at the bearing 29. It is supported freely. Accordingly, the chamber chamber drum 2 is rotatable with respect to the gun mount 41 and the cam drum 43.
[0019]
On the rear side of the cylindrical portion 2a of the chamber chamber drum 2, a plurality (eight) of luma guide grooves 2d are formed in accordance with the chamber 25, and the rammer 44a is slidable in each of the rammer guide channels 2d. Is engaged. In addition, ammunition holding portions 2b are provided on both sides of each ramp guide groove 2d in the outer diameter direction as a predetermined interval in the front-rear direction, and a semicircular ammunition guide portion 2c is formed by a pair of opposing ammunition holding portions 2b. Is forming. The ammunition holding unit 2b and the ammunition guide unit 2c correspond to the loading unit 3 described above. The ammunition 24 is fed from the bullet feeder 9 through the bullet feeding hole 47 shown in FIG. 2 and is sent to a predetermined ammunition guide portion 2 c located behind the chemical chamber 25. At the location corresponding to the bullet feed hole 47, the runner 44a takes the most retracted position as shown by the phantom line in FIG. 5, and the ammunition 24 is successively supplied in front of the runner 44a taking this position.
[0020]
The cam drum 43 is individually formed with a plurality of (eight in this example) endless helical cam grooves 43b on the rear half thereof, that is, on the outer peripheral surface behind the drug chamber 25. The projecting portions 44b of 44a are slidably engaged with each other. Thus, each rammer 44a can be moved back and forth between the ammunition holders 2b behind the chamber 25 along the shape of the cam groove 43b while being guided by the respective rammer guide grooves 2d.
[0021]
If the chamber drum 2 is rotated by one step (45 °) in one direction (direction of arrow A shown in FIG. 2) by the intermittent drive mechanism 6, each ramper 44a has a groove shape, that is, an inclination of the cam groove 43b to be engaged. Move forward or backward accordingly. Each rammer 44a advances five steps between the chambers 25a to 25f shown in FIG. 2 to push the ammunition 24 into the chamber 25 and push the cartridge case 24 "remaining in the chamber 25 forward. A maximum of 3 steps of retraction is performed between 25f and 25a and the original position is restored between the chambers 25f and 25a, and it is possible to return the rammer 44a to the original position in one step. Can also incorporate a stop step that does not move forward or backward in each of the lumbers 44a, but the machine gun performs an operation of pushing the ammunition 24 into the chamber 25 so that the cartridge case 24 "remaining in the chamber 25 is moved forward. It constitutes a push-through system that is pushed out and discharged.
[0022]
Next, the operation will be described.
Now, it is assumed that the ammunition 24 successively supplied from the bullet feed holes 47 is held in the respective ammunition guides 2c (loading unit 3) or the drug chamber 25. At the start of shooting, first, the drive unit 22 is activated, and the ammunition 24 in the ammunition supply path 11 e is sent until it comes into contact with the lower portion of the bullet feeding claw wheel 17. The intermittent drive mechanism 6 is started after this extremely short time. If the chamber drum 2 is rotated by one step (45 °) in one direction (direction of arrow A shown in FIG. 2) by the intermittent drive mechanism 6, each ramper 44a has a groove shape, that is, an inclination of the cam groove 43b to be engaged. Move forward or backward accordingly. FIG. 2 shows an example in which the runner 44a has five steps forward and three steps backward (and stopped) along the cam groove 43b. Ranma 44a, which takes five steps forward while corresponding to the chambers 25a to 25f, performs an operation of pushing the ammunition 24 into the chamber 25, and simultaneously performs an operation of pushing out and discharging the cartridge case 24 "remaining in the chamber 25 forward. In addition, the rammers 44a that take the backward step while corresponding to the chambers 25f to 25a return to the initial position by performing the backward operation, so that the chamber chamber drum 2 is intermittently rotated 360 °. The ramper 44a performs forward and backward (and stop) eight steps.
[0023]
In this cannon, the ammunition 24 is loaded toward the chambers 25a to 25f before matching the barrel 30 and fired after reaching the chamber 25g, and the cartridge case 24 "remaining in the chamber 25 is newly added. The ammunition 24 is pushed forward by the loading of the ammunition 24. Accordingly, the retreating operation of the rammer 44a is performed irrespective of the ammunition 24 (or the cartridge case 24 ").
[0024]
In the state where the ammunition 24 is fed from the bullet feeding hole 47 to the loading portion 3, that is, the ammunition guide portion 2c, as described above, the rammer 44a takes the most retracted position as shown by the phantom line in FIG. Thereafter, as the chamber drum 2 rotates, the rammers 44a start moving forward, and the ammunition 24 is gradually pushed into the chamber 25 while corresponding to the chambers 25a to 25f, and the loading is completed. While corresponding to the chambers 25a to 25f, the front of the chamber 25 is still open without being hindered by the gun barrel 30, so that the cartridge case 24 "remaining in the chamber 25 is pushed forward. New ammunition 24 is loaded.
[0025]
Thereafter, the ammunition 24a is moved backward while leaving the ammunition 24 in the chamber 25, and the rear portion of the chamber 25g is closed by the closing portion 41a at the position of the chamber 25g at the lower end. In this state, the ammunition device 24 is fired by the action of the firing device, the bullet 24 'is fired from the gun barrel 30, and the cartridge case 24 "remains in the chamber 25g. The rammer 44a is appropriately positioned between the chambers 25f to 25a. To the original position shown in FIGS. 1 and 5.
[0026]
Next, the operation of the bullet feeder 9 will be described.
When the chamber drum 2 and the first gear 4 are driven by the intermittent drive mechanism 6 and rotate in the direction of arrow A shown in FIG. 2, the shaft 20 and the second gear 5 meshing with the first gear 4 are actuated. The ammunition wheel 17 rotates in the direction of the arrow B shown in FIG. 2, and the ammunition 24c that is sent in advance by the drive unit 22 and is held at the lower part of the ammunition wheel 17 is the loading unit 3, that is, the ammunition guide unit 2c. Is sent to. At the same time as the ammunition 24 c is fed into the loading unit 3, the function of the drive unit 22 drives the shaft 21 and the chain wheels 14 and 15 to rotate, and the push bar 23 moves via the chains 7 and 8. Therefore, the ammunition 24 is pushed, and the next-order ammunition 24 in the ammunition supply path 11e is sent to the lower side of the bullet feeding claw wheel 17. As described above, the drive unit 22 has a function as a spring motor, and constantly urges the rotation of the shaft 21 by a stored force including a built-in spring, a torsion spring and the like. In this way, the ammunition 24 sent to the loading unit 3 is pushed into the chamber 25 by the rammers 44a while the ammunition 24 is successively fed to the loading unit 3 in conjunction with the intermittent rotation of the chamber drum 2. You can continue. When the chamber 25 loaded with the ammunition 24 comes to the chamber 25g at the position of the gun barrel 1, the bullet 24 'is fired as described above.
[0027]
When the bullet 24 ′ is fired, the reaction chamber drum 2 moves backward by the reaction and is buffered by the function of the seating / returning seating mechanism 40. However, the meshing state of both gears 4 and 5 is maintained during this time, the rotation of the chamber drum 2 is transmitted to the second gear 5, and ammunition feeding from the bullet feeder 9 to the loading unit 3 is continued. Done.
[0028]
In the bullet feeder 9, the shaft 21 and the chain wheels 14 and 15 are driven to rotate by driving of the drive unit 22, while the chain wheels 12 and 13 are driven via the chains 7 and 8 by rotation of the chain wheels 14 and 15. Rotates. By driving the chains 7 and 8, the ammunition 24 in the ammunition supply path 11 e is pushed by the push bar 23, and the push bar 23 moves the chain wheels 12, 13, 14 and 15 and the sprockets 16 and 18 for ammunition one after another. The ammunition 24 is replenished immediately below the bullet feeding claw wheel 17 while passing through.
[0029]
The bullet feeding wheel 17 is rotated by the intermittent drive mechanism 6 via both gears 4 and 5. As described above, the intermittent rotation of the chamber drum 2 by the intermittent drive mechanism 6 is set so that the speed is low at the start and end of the intermittent rotation and the intermediate rotation speed is high. As a result, the feeding speed of the ammunition 24 by the bullet feeding claw wheel 17 is also low at the start of feeding and at the end of feeding, like the chamber drum 2. As a result, it is possible to prevent the ammunition 24 from being fed into the loading unit 3 at a high speed and colliding strongly. The next-stage ammunition 24 fed below the bullet feeding claw wheel 17 is fed while being guided by the claw portion of the bullet feeding claw wheel 17 in the low-speed rotation state at the end of the intermittent rotation. Thereby, it is suppressed well that ammunition 24 is sent into bullet feeding claw wheel 17 at high speed, and collides strongly.
[0030]
When the bullet 24 ′ is fired, there may be a case where the next bullet 24 ′ is fired before the chamber drum 2 is fully advanced and returned by the function of the retracting and retracting mechanism 40. In any case, both the gears 4 and 5 are manufactured in such a width that the meshing state of both the gears 4 and 5 is maintained even when the chamber drum 2 is fully advanced and returned, and even when the chamber drum 2 is fully retracted. ing.
[0031]
Even when the shooting is started again after stopping the shooting, first, the drive unit 22 is activated, and after the extremely short time required to send the ammunition 24 in the ammunition supply path 11e to the bullet feeding claw wheel 17 has elapsed, The drive mechanism 6 is controlled to start. As a result, there is no blank of the ammunition 24 in the loading section 3 and no shooting is interrupted.
[0032]
If the ammunition 24 in the ammunition supply path 11e has decreased, the rotational drive source 22 is driven in reverse rotation to return the push bar 23 to the vicinity shown in FIG. Push in the ammunition 24. The pushed ammunition 24 is loaded up to the push bar 23 while rotating the ammunition sprocket 16 rotatably supported on the shaft 19. Since the ammunition sprocket 18 is rotatably supported by the shaft 21, the ammunition 24 can be pushed also into the bullet feeding claw wheel 17 side.
[0033]
By the way, in the above-described one embodiment, the protrusions 44b of the respective rammers 44a are slidably engaged with the cam grooves 43b of the cam drum 43 so that the rammers 44a are guided by the rammer guide grooves 2d. According to the groove shape of the groove 43b, it was moved back and forth between the ammunition holders 2b. However, the ramper mechanism 44 may be a loading mechanism that is operated by a drive mechanism that is separate from the intermittent drive mechanism 6 to push the ammunition 24 into the predetermined chambers 25a to 25f before shooting. .
[0034]
【The invention's effect】
As can be understood from the above description, according to the ammunition delivery method of the revolver type cannon according to the present invention, the following effects can be obtained.
Delivery of ammunition from the bullet feeder to the loading section is performed in conjunction with intermittent rotation of the chamber drum. This intermittent rotation of the chamber drum is a motion of relatively small acceleration and deceleration, and in particular, since the speed at the end of the intermittent rotation is slowing, the rotation of the feeding pawl wheel linked to this is the same, Sudden collision motion to the loading unit as in the conventional example is suppressed. In addition, the ammunition in the bullet feeder also becomes a collision while being received by the bullet feeding claw wheel having a relatively low rotational speed, and the impact is similarly mitigated.
[0035]
For this reason, even if the strength of the ammunition, particularly the cartridge case, is reduced, it is difficult to produce a dent, and it is possible to prevent problems associated with this dent, and it is possible to reduce the size and weight of the ammunition. In addition, the strength of the bullet feeding section from the bullet feeder to the loading section can be similarly reduced, and it is possible to satisfactorily prevent problems such as deformation. Furthermore, as a result of the reduction in size and weight of ammunition, not only the storage space for ammunition is reduced, but also the driving force required to transfer and load ammunition is reduced, and the cannon can be miniaturized. .
