Detailed Description

The present invention will be described in further detail below.

As shown in fig. 1-5, a ammunition feed device based on multi freedom degree pipeline is applied to the barrel 22 of launching the bullet, including the driver plate 1, the thumb wheel 2, drive arrangement and the first curved pipeline, the first straight pipeline, the second curved pipeline and the second straight pipeline that are the rigidity piece, the thumb wheel 2 wears to locate the driver plate 1 middle part, drive arrangement locates thumb wheel 2 one side, be used for driving the thumb wheel 2 to rotate, the driver plate 1 is equipped with the export pipeline, the first curved pipeline, the first straight pipeline, the curved pipeline of second and the second straight pipeline are end to end connected in proper order, the second straight pipeline tail end is used for connecting the barrel 22.

Because first curved pipeline, first straight line way, the curved pipeline of second and second straight line way are the rigidity piece, consequently the ammunition feed pipeline can not cause the jam in the ammunition feed pipeline because of warping. Because outlet pipeline, first curved pipeline, first straight line way, second curved pipeline and second straight line way end to end connection in proper order, through setting up the pipeline connected mode of different angles and setting up different arc radiuses for first curved pipeline and second curved pipeline, the ammunition feed pipeline can realize wide-angle turn and multi freedom ammunition feed, has better ammunition feed effect.

Compared with the totally enclosed type ammunition supply pipeline commonly used in the prior art, the embodiment of the invention has the advantages that the gaps are reserved among the adjacent first arc-shaped pieces, the adjacent first straight connecting pieces, the adjacent two second arc-shaped pieces and the adjacent second arc-shaped pieces, on the premise of ensuring the strength, the whole weight of the ammunition supply pipeline is reduced, and the contact area of the ammunition pill with the inner wall of the ammunition supply pipeline is smaller when the ammunition pill passes through the ammunition supply pipeline, so that the friction is reduced, the forward resistance is reduced, the ammunition discharging speed is improved, and the heat dissipation effect is better. Meanwhile, if the ammunition supply pipeline breaks down, people can find and repair the fault through the gaps more easily, and the maintenance is more convenient.

The first arc radian is 90 degrees, and the second arc radian is 180 degrees.

Specifically, the first arc-shaped part and the second arc-shaped part are respectively vertically arranged (the included angle between the second arc-shaped part and the horizontal plane is variable). After the shot is ejected from the outlet pipeline of the driving plate 1, the shot enters the first bent pipeline from the upper end of the first arc-shaped part, rolls downwards along the inner side of the first arc-shaped part and enters the first straight pipeline through the lower end of the first arc-shaped part, and the travelling path of the shot is adjusted by 90 degrees by utilizing the first bent pipeline. The projectile comes out from the tail end of the first straight pipeline, enters the second curved pipeline from one end of the second arc-shaped part, rolls downwards, enters the second straight pipeline from the other end of the second arc-shaped part, and the travelling path of the projectile is adjusted by 180 degrees by means of the second curved pipeline. Through the adjustment, the ammunition supply pipeline with multiple degrees of freedom is realized.

In the embodiment, the outlet pipeline of the drive plate 1 is perpendicular to the first straight pipeline and the second straight pipeline, the first straight pipeline is parallel to the second straight pipeline, and the shot travelling direction realizes turning at a large angle on the basis of multiple degrees of freedom.

The lubricating device comprises a plurality of second cylinders restrained by the carbon rods 11, the second cylinders are sequentially arranged at the adjacent connecting positions of the outlet pipeline, the first bent pipeline, the first straight pipeline, the second bent pipeline and the second straight pipeline along the passing path of the shot, and the shot rolls on the second cylinders.

When passing through the second cylinder of the bullet, external force is applied to the second cylinder to enable the second cylinder to rotate, so that the bullet is assisted to turn at the joint of each pipeline and change the speed and direction, the bullet is prevented from being blocked due to the extrusion of subsequent bullets at the turning position, and carbon powder generated by the carbon rod 11 due to abrasion can play a role in lubrication, and the advancing resistance of the bullet can be effectively reduced.

The extension direction of the outlet pipeline of the dial plate 1 corresponds to the dial wheel 2.

Specifically, a circular ring-shaped track is arranged in the drive plate 1 and surrounds the drive wheel 2. The outlet of the circular ring track is communicated with an outlet pipeline of the driving plate 1, and the outlet pipeline of the driving plate 1 is positioned in the normal direction of the circular ring track.

The inner side part of the drive plate 1 is rotatably connected with a third cylinder, and the third cylinder is arranged close to an outlet pipeline.

Because the outlet pipeline of the driving plate 1 is arranged in the normal direction of the circular track, the projectile can firstly impact the inner side part of the driving plate 1 close to the outlet pipeline before being stirred by the driving wheel 2 to be ejected out of the outlet pipeline of the driving plate 1, the friction force between the projectile and the inner side part of the driving plate 1 is large, and the ejection speed of the projectile is reduced. By arranging the third cylinder on the inner side part of the drive plate 1, when the shot impacts on the third cylinder, the friction force between the third cylinder and the shot is reduced through self rolling, the shooting speed of the shot is kept to the maximum extent, and the shot is output more smoothly.

The two inner sides of the outlet pipeline are respectively and rotatably connected with a first cylinder.

After the shot impacts the first cylinder from the circular ring-shaped track, the travel path of the shot is arc-shaped, and the shot can impact the side part of the outlet pipeline when entering the outlet pipeline. Therefore, the first cylinders arranged on the two inner sides of the outlet pipeline reduce the friction force between the first cylinders and the shot through self rolling, and the shooting speed of the shot is kept as much as possible while the advancing direction of the shot is adjusted.

The stand is used for continuously disturbing the shots in the inner cavity of the driving plate 1 when the driving wheel 2 rotates, so that the shots are prevented from bridging, the shots are ensured to smoothly fall between the driving rods of the driving wheel 2, and the ejection speed is improved.

The driving plate 1 is internally provided with a brush 5, the brush 5 is fixedly connected with the driving plate 1, and the side wall of the upright post of the driving rod is provided with a groove which is matched with the brush 5.

The driver plate 1 lateral wall is equipped with the draw-in groove, and brush 5 installs in the draw-in groove of driver plate 1, and is fixed through the hot melt adhesive.

The brush 5 is used for disturbing and layering the bullets among the shift levers of the shift wheel 2, preventing the bullets on the upper layer from extruding the bullets on the lower layer to cause material blocking or bridging and preventing the bullets on the upper layer from directly falling to the outlet pipeline to cause material blocking on the outlet pipeline.
