A mechanism for replenishing a projectile dispensing mechanism

Abstract

The application belongs to the field of weapon technology and relates to a mechanism for supplementing bullets to a bullet throwing mechanism. When the bullet supplementing mechanism is located above the throwing mechanism, a motor drives a lead screw to rotate, thereby enabling a bullet pushing ring to push the upper layer of bullets to move downward along a bullet pushing ring movement groove. Meanwhile, the bottom bullet pushing block of the upper layer of bullets is in contact with the metal reinforcing ring of the middle layer of bullets, and the middle layer of bullets is pushed to move downward. When the middle layer of bullets moves to a specified position, the lead screw stops rotating. When the bullet supplementing mechanism is located below the throwing mechanism, the bullet supplementing mechanism moves upward under the drive of the ball screw of the ball screw pair, and the uppermost layer of bullets is supplemented into the bullet clamp by the bullet tray. The application can enable the same parent bullet to be equipped with multiple different bullet drugs. The bullet supplementing mechanism is used to load bullet drugs, the throwing mechanism can be repeatedly actuated, and the utilization rate is high under the constraint of the same mechanism mass design level.

Generally, the cluster bomb is composed of a mother bomb, bullets and a throwing mechanism. The mother bomb serves as a carrier and provides a space for the bullets and the throwing mechanism. The throwing mechanism is controlled by a program and uniformly throws the bullets from the mother bomb at a certain time and place, so that the bullets can cover a specific target area. The number of bullets is generally large, and the number can compensate for the aiming error and shooting accuracy error, thereby improving the task success rate or improving the killing power and killing range. Such a combat mode makes the deterrent ability, attack ability and destruction efficiency of the cluster bomb much higher than those of the same level single or small batch continuous bombs.
