When the electric gun (E) ignites the explosive (D) in the shell (C) of the completed ammunition (A) loaded in the barrel of the tank and explodes, the explosive pressure is Shell (B)
This causes the shell (B) to be fired from the barrel together with the shell (F), and immediately after this shot, the shell (F) is divided by the wind pressure acting on its front center (F 1 ). Is separated from the cannonball (B), and only the cannonball (B) flies toward the shooting target while emitting light. At this time, as the bullet shell (F) is separated, the ejection pins (12) at the rear of the shell (B) are ejected outside the ammunition body (1), and the ejection members (5) are ejected by the ejection pins (12). The restriction of forward movement against is released. Further, during the flight of the shell (B), the rotation assisting blade (44) is relatively rotated by receiving the wind pressure, and is screwed and fastened to the base portion (45) thereof as the rotation assisting blade (44) rotates. The shaft (8) rotates and its male screw portion (8a) and the female screw hole (5
The engagement with (a) is loosened and the actuating member (5) gradually advances.

Then, after a certain time has passed since the firing of the shell (B),
When the cumulative number of rotations of the rotation assist blade (44) reaches a predetermined value, the male screw portion (8a) of the shaft (8) comes out from the female screw hole (5a) in the actuating member (5) and the shaft (8). And the actuation member (5) are released from each other, whereby the actuation member (5) rushes forward by the urging force of the spring (10), and the firing pin (7) at the front end strikes the detonator (3). The crushing agent (4) is detonated, and the projectile (1) is divided and crushed by the explosion of the crushing agent (4).

On the other hand, in parallel with this, the warhead (30) from the bullet (1)
Is separated. That is, each of the ejection pins (23) in the bullet body (1) is ejected to the outside of the bullet body (1) by the urging force of the spring (24) due to the separation of the bullet shell (F), and the inside of the rod insertion hole (16). Of movement of the rod (17) is released. This release causes the rod (17) to move the warhead separation spring (2
The urging force of 1) gradually moves forward while receiving the movement resistance of the timepiece mechanism (25) in the warhead (30), and when the predetermined time set by the timepiece mechanism (25) elapses, the small diameter part of the rod (17). (17a) reaches the position corresponding to each warhead fixing pin (19), and the restriction on each warhead fixing pin (19) on the outer peripheral surface of the rod (17) is released. With the release of the restriction, each warhead fixing pin ( 19) causes the rod insertion hole (1
6) It moves into the inside of the pin insertion hole (18), and the tip of the bullet is removed from the warhead (30 and the bullet (1).
The warhead (30) is thus separated from the bullet (1).

Therefore, in this case, the bullet body (1) of the shell (B) is automatically divided and crushed after a certain period of time elapses after being fired from the barrel, and the warhead (30) is ejected from the bullet body (1).
Since the shell is separated, even if the shell (B) flies without hitting the target or jumps by rubbing the target, the shell (B) automatically stalls and falls. Therefore, it is possible to reliably prevent the cannonball (B) from flying to an area away from the target.

尚、上記実施例では、破砕薬(4)の爆発によって弾

For example, as shown in FIG. 5, a shaft (26) is placed through the center of a bullet (1 ') that can be divided into three, for example, in the radial direction from the center position, and the warhead is placed at the front end of the shaft (26). While fixing the (30 '), the rotation assisting blade (44) is screwed to the rear end of the shaft (26), and when the cumulative number of rotations of the rotation assisting blade (44) reaches a predetermined value, the assisting blade (44) ) And the shaft (26) are released from the screw connection, and the shaft (26) is pulled out by the urging force of the spring (28) to separate the warhead (30 ') from the ammunition body (1'). 1 ') may be divided into bamboo splits by wind pressure.
