When the recording is made, the barrel 110 is returned to its original position by the main retractor 130, which is provided on both sides of the barrel 110 and serves as a buffer, and repeats the operation of recording when the shot is made again. .

In addition, the upper portion of the barrel assembly 100 in Figure 7 is equipped with a loading device for loading the shell.

The pomi device according to an embodiment of the present invention having such a structure will be described in detail for each of three modes (safe mode / falling mode / triggering mode).

[Safe mode]

As shown in FIG. 8, when the rod 52 is pushed out while pushing the link 92 by the operation of the first solenoid valve 50, the link 92 is rotated about the support pin 95 and the pin 93 is rotated. The lever 94 coupled in the rotation is rotated in one direction (safe mode direction).

At this time, the lever 94 is coupled to the shaft 24, the shaft 24 is also rotated at the same time as the lever 94 is rotated, and then coupled to the shaft 24, the lower portion of the cover 22 The shooting mode selection member 20 is also rotated at the same time.

9A and 9B, the ball 30 in the interior of the housing 10 has elasticity toward the ball nut 34 by the side of the shooting mode selection member 20. While pressing the member 36 is pushed at the same time according to the push, at this time, the ball hammer 40 located on the opposite side of the shooting mode selection member 20, even if the ball hammer clasp 80 is pushed upward to trigger the ball (30) ) And the interval (g) is not hitting the ball 30 is made.

The rod 52 of the solenoid valve 50 is once retracted and immediately retracted to be in place.

At this time, the rod 62 and the link 92 of the second solenoid valve 60 located on the opposite side are provided so as not to interfere, so that the link 92 can be smoothly pushed.

In other words, in the safe mode, the ball 30 is blown due to the distance g between the ball 30 and the ball hammer 40 by the rotation of the shooting mode selecting member 20 regardless of the state of the recoking. You will not lose.

[Falling Mode]

As shown in Figs. 11A and 11B, in the drop mode, the first and second solenoid valves 50 and 60 are operated at the same time so that each of the rods 52 and 62 is drawn out at the same time. To be placed in the center position.

Then, according to the position of the shooting mode selection member 20, the ball 30 inside the housing 10 is guide member 32 by the side of the shooting mode selection member 20 toward the ball nut 34, the elastic member ( The ball 30 is pushed out of the ball nut 34 as it is pushed at the same time as it is pressed while compressing.

At this time, the ball hammer 40 is retracted from the pre-triggered recoking state and is caught by the end portion 80b of the ball hammer clasp 80, and is operated by a separate solenoid valve (not shown). While the end portion 80a is pushed and the elastic member 82 is compressed, the end portion 80b moves downwardly about the rotational shaft 84 to release the engagement state with the ball hammer 40, thereby triggering the ball state. The ball hammer 40 is in a state of being spaced apart by the shooting mode selection member 20.

Accordingly, when the shell is mounted in the barrel 110 of the barrel assembly 100 and dropped, the ball 30 is moved into the housing 10 of the foaming device 1 coupled to the rear of the barrel 110 so that the ball 30 protrudes. The shot is made by hitting the detonator of the shell.

In the drop mode, the ball 30 always protrudes out of the ball nut 34 according to a change in the position of the shooting mode selection member 20 regardless of the recoking state.

[Triggering mode]

As shown in FIG. 12, in the triggering mode, the lever 94 rotates toward the triggering mode while the link 92 is pushed by the operation of the rod 62 of the second solenoid valve 60, and FIGS. 13A and FIG. As shown in 13b, in the state of pre-recording by the recoiling lever 70 (the ball hammer 40 is retracted), the rod 62 of the solenoid valve 60 is advanced and the shooting mode selection member (20) rotates to the trigger mode position (in the waiting state), and when the trigger is made by the operation of the solenoid valve, the state in which the ball hammer 40 is caught from the ball hammer clasp 80 is released, and the elastic member is released. The ball hammer 40 is advanced by the repulsive force of 42, and the ball 30 is projected by striking the ball 30 in the through hole 20a of the shooting mode selection member 20, thereby protruding to the outside of the ball nut 34. It becomes a state.

At this time, the guide member 32 is also in a state of moving while compressing the elastic member 32. Then, in the state where the shell is loaded into the barrel 110 in advance, the ball 30 is projected to the outside of the ball nut 34, hitting the detonator of the shell is made to shoot the shell.

In the triggered mode, the trigger is always possible when the recording is in the recording state.

When the shell is fired, the breech unit coupled with the barrel is retracted by the main retreat unit 130, and at this time, the recoking lever 70 is rotated to recoke so that the trigger is possible in the triggering mode.

Here, since the recording lever 70 is provided inside the support block 120 and is inserted into the groove 122 formed in the inner surface of the support block 120 so as to be movable, the shell S may be moved. When the barrel 110 is retracted by firing, the recording lever 70 is rotated while moving from the area a1 of the groove 122 to the area a2.

In other words, although the depths of the regions a1 and a2 of the grooves 122 are different from each other, the depth of the region a1 is formed deeper than the depth of the region a2, so that the recording lever 70 is deep. Since it moves from low to low, it is rotated by the difference, and then, as shown in Figure 2, the pivoting link 74 connected through the pivoting lever 70 and the shaft 72 is a ball hammer ( The recording is performed while moving (retreating) 40).

When the recording is made, the barrel 110 is returned to its original position by the primary restoring device 130, and when the firing is made again, the repetitive operation is performed.

When firing in the drop mode, the ball hammer 40 is caught by the ball hammer clasp 80, and the recorder lever 70 is rotated even if the ball hammer 40 is already used for the ball hammer. Since the state is caught in the latch 80, the recording is completed.

In addition, in the triggering mode, the solenoid (not shown) for triggering is activated to push the ball hammer catch 80 upward to release the locking state with the ball hammer 40, and the ball hammer 40 Strike 30, the ball 40 hits the detonator of the shell (S) is made to shoot.

At this time, the ball hammer 40 is caught by the ball hammer clasp 80 again by the operation of the recording lever 70 to repeat the process of recording.

Although the present invention has been described with respect to the mortar foaming device, the present invention is not limited thereto, and may be mounted on the rear of other weapons.
