Description

Double-tube bullet-sending device with double-helix bullet supply

Technical Field

The invention is based on a double-shaft steering cradle head-suspension moving platform, and is practically applied to a double-spiral ammunition feeding double-pipe ammunition device in a special environment.

Background

The double-tube launching device for double-helix ammunition feeding is a research direction of military shooting, and has the functions of freely turning to any direction, hitting any target and the like. In the existing special environment combat products, the ammunition is mostly designed for single-tube and single-bin ammunition supply, and double-tube launching is not common. Compared with double tubes, the existing single tube design has the advantages of low projectile velocity and small loading capacity. The double-tube double-bin design is too bulky. For the design of the bullet tube, the situation that the bullet is blocked in the bullet tube can occur more or less in the existing bullet tube design, and the influence on the bullet feeding speed is great. As for the existing launching device, the existing launching device cannot be hung on a tripod head moving at the bottom and cannot be used in a special high-altitude environment, so that only one of the two methods is selected for double-tube launching and hanging movement, and the universality under different environments is greatly limited. In summary, no fort design capable of integrating all advantages is available.

Disclosure of Invention

The invention is used for solving the problems of low launching speed, large volume and easiness in bullet clamping, and provides a mechanical structure design scheme of a double-barreled launching device with double-layer magazine ammunition supply. The double-tube launching device has the innovation points that the double-magazine ammunition feeding, the double-helix ammunition feeding, the double-tube launching and the design that the ball is used at the turning part of the ammunition tube are adopted.

The first innovation is the double spiral feed. Firstly, the double-spiral feeding bullet is made of a special driving plate, and the strength of a mechanical structure is improved. Secondly, as the double-spiral track is used, more compact space is used for conveying bullets, and the volume of the magazine is reduced on the premise of meeting performance requirements; thirdly, solve the last several pills and be difficult to get into the problem of thumb wheel, compare the scheme of single spiral, the bullet is rotatory more level and smooth.

The second innovation is dual-tube firing. The two ball paths respectively convey bullets for the two launching devices, so that double-tube launching effectively improves radio frequency, and the total radio frequency can reach twice of that of single-tube launching. The high-speed rotating brushless motor and the friction wheel extrude the bullet, and great kinetic energy is generated at the launching port to meet the launching requirement.

The third innovation point is the design of using the ball at the turning part of the spring tube. The design of the ball bearings can reduce the friction of the bullet at the right-angle reversing position of the ball path, better enable the bullet to smoothly pass through the turning of the pipeline, and reduce the bullet clamping probability in the bullet conveying pipe; the ball makes the pipeline bear the axial force and can extend the smooth sharing of connecting piece direction, has reduced the requirement to the pipeline material, and the corner of the bullet pipe of whatever material can both let the bullet pass through fast. And a separate driving part is not used in the ball path, so that the control matching precision requirement of each part is reduced, and the system reliability is improved.

Advantageous effects

The double-tube launching device for double-helix ammunition feeding has the characteristics of flexibility, compactness, stable ammunition feeding, large ammunition carrying capacity, quick ammunition feeding and the like, and is suitable for quick projectiles in a suspension environment. Wherein the pellet storage mechanism and the supply mechanism are innovative points.
