The working process of the invention is as follows:
firstly, loading: the steering engine rotates to the projectile throwing position after being powered on. The limiting plate is jacked upwards by the steering engine through the rocker arm and the connecting rod, the limiting plate is completely separated from the magazine fixing seat, the limiting effect is lost, and the magazine can be directly rotated forwards by hands at the moment. When the shell position is rotated, a tear bomb is loaded from the upper part of the shell of the magazine. When loading, the pull ring is loaded downwards vertically, and the pull ring is clamped at the bottom of the magazine chute. At the moment, the pull ring is supported by the shell of the bomb bin, so that the tear-gas shells cannot fall down from the bomb throwing port. The magazine is shifted forward by hand and tear shells are loaded in sequence.
Secondly, resetting: the steering engine works, and the pushing tongue is driven by the rocker arm to retreat outside the limiting plate. In the process, as the limit plate is still jacked up by the push tongue when the rotation is just started, the limit is in a failure state, and therefore the magazine can be pushed. And because the steering engine drives the connecting rod to push the push tongue to the maximum stroke amount during loading, and the limit column on the push tongue is clamped between two teeth of the ratchet wheel, when the steering engine rotates to the reset position, the limit column on the push tongue can drive the magazine to rotate forwards by one elastic position. When the steering engine rotates to a certain stroke amount, the push tongue retracts and is completely separated from the limiting plate, the limiting plate is completely released, and then the protrusions on the limiting plate are pressed into the limiting groove of the magazine fixing seat under the action of the pressure spring to lock the magazine fixing seat, so that the limiting effect is achieved. In the rotating process of the whole magazine fixing seat, the tear bomb pull ring slides in from the guide groove at one end of the steering engine fixing seat and is hooked by the claw at one end of the rocker arm of the steering engine, and the resetting is completed at the moment.
Thirdly, throwing: the steering wheel work drives the hook claw and draws the pull ring of tear-gas shells to move outwards, and when the pull ring on the tear-gas shells is pulled out completely, the tear-gas shells lose the supporting function, slide out from the bomb port of the lower cover plate under the action of gravity, and bomb throwing is completed. Simultaneously at this in-process, the steering wheel rocking arm drives pushing away the tongue that pushes away of pull rod and can jack up the limiting plate gradually, and arch and the separation of magazine fixing base on the limiting plate for the spacing inefficacy of rotation of magazine fixing base, and when the steering wheel rotated to the maximum stroke volume, pushed away inside the spacing post card on the tongue can get into the ratchet, waited for next time to reset. The resetting step and the bomb throwing step are alternately and circularly carried out, each cycle is one bomb throwing period, namely, one bomb throwing is carried out until all the tear shells in the wheel disc type magazine are thrown.
The invention has the advantages that: the tear bomb throwing mechanism is simple and compact in structure, low in part processing difficulty, easy to obtain accessories, and compatible and universal; the loading capacity is large, and a plurality of tear shells can be loaded at one time; the security is higher, even the mechanism trouble causes the input failure, because the restriction of magazine can not cause the magazine to arouse in the magazine. The throwing period is short, a plurality of tear shells can be thrown out in a very short period, and the killing effect is greatly enhanced.
