Description

Double-layer spiral bullet-poking device

Technical Field

The invention relates to a bullet poking device, in particular to a double-layer spiral bullet poking device.

Background

The bullet device of dialling of present robot mostly uses the individual layer driver plate to dial the bullet, and the bullet exit adopts single bearing to reduce the friction between bullet and the capsule, but this kind of design can cause the phenomenon that produces empty bullet because of the restriction of driver plate shift fork quantity when the bullet is fired to the card bullet problem appears.

Disclosure of Invention

The purpose of the invention is as follows: the invention aims to provide a double-layer spiral bullet-poking device which does not generate the problems of empty bullets and bullet jamming and has high radio frequency.

The technical scheme is as follows: the invention provides a double-layer spiral bullet-poking device which comprises a bullet cabin with a circular cross section and coaxially arranged, a double-layer spiral drive plate, a track bottom plate and a motor arranged at the bottom, wherein the double-layer spiral drive plate is positioned in the bullet cabin, a bolt is arranged on the inner side wall of the bullet cabin, a plurality of bearings are sleeved on the bolt, nuts are matched with the end part of the bolt, the drive plate is positioned on one side, close to a bullet outlet, of the bearing, the bottom of the drive plate is higher than the upper cross section of the bearing, the drive plate is not contacted with the double-layer spiral drive plate, the bearing is positioned between shifting forks at the edge of the double-layer spiral drive plate, a track baffle is arranged on the track bottom plate, a track communicated with the bullet outlet is formed below the drive plate, a straight edge of the track baffle and the inner side wall of the bullet cabin, and is used for lower-layer bullets to pass, and the shifting forks are distributed at intervals at the edge of the double-layer spiral drive plate.

The horizontal plane for the double-layer spiral dial in the technical scheme is cut into innumerable planes from bottom to top, each plane from the second surface to the top rotates by a very small angle around the vertical central line of the dial than the next surface, and the planes are overlapped to form the spiral dial.

Has the advantages that: the invention can not generate the problems of empty bullets and bullet jamming when in use, and can also improve the shooting frequency to more than 15 bullets per second.

Detailed Description

As shown in fig. 1-3, the double-layer spiral bullet-shifting device of this embodiment includes a coaxially disposed bullet cabin 4 with a circular cross section and a blocking piece 10, a double-layer spiral dial 3, a track bottom plate 6, and a motor 9 disposed at the bottom, wherein the double-layer spiral dial 3 is disposed inside the bullet cabin 4, a bolt 7 is disposed on the inner side wall of the bullet cabin 4, a plurality of bearings 1 are sleeved on the bolt 7, the end of the bolt 7 is adapted to a nut 5, the blocking piece 10 is disposed at one side of the bearing 1 near the outlet of the bullet 8, the bottom of the double-layer spiral catch plate is higher than the upper tangent plane of the bearing 1, the catch plate 10 does not touch the double-layer spiral catch plate 3, the bearing 1 is positioned between the shifting forks 11 of the double-layer spiral catch plate 3, the track bottom plate 6 is provided with the track baffle plate 2, the straight edge of the track baffle plate 2 and the inner side wall of the bullet cabin 4 form a track communicated with the outlet of the bullet 8 for the bullet 8 at the lower layer to pass through, and the shifting forks 11 are distributed at intervals at the edge of the double-layer spiral catch plate 3.

The shape of the vertical projection of the blocking plate 10 of this embodiment is a sector with the center of the dial as the center of the circle. The track guard 2 of the present embodiment is preferably rectangular. Other shapes that achieve equivalent functions are within the scope of the invention. The number of bearings 1 is preferably 4. 4 bearings are suitable for shot with the diameter of 17mm, and if the number of the bearings 1 is less than 4, the shot 8 is too close to the center of the driving plate to touch the bearing 1 when passing through the bearing 1, so that the bearing 1 cannot play a role; the number of bearings is more than 4, resulting in that the 5 th and above bearing 1 is too close to the centre of the dial and no 17mm shot can be hit. Of course, it is within the scope of the present invention to correspondingly adjust the number of bearings 1 corresponding to different diameters of the projectile 8 to achieve the corresponding function. The end of the fork 11 of this embodiment is shaped to have two sides inclined. Therefore, the pushing force of the shifting fork to the projectile has a vertical downward component, and other shapes capable of realizing the functions also fall into the protection scope of the invention.

The working principle is as follows: when the bullet is enough many in the capsule, double-deck spiral driver plate can make the bullet overlap the range with the cyclic annular and be double-deck between the shift fork of double-deck spiral driver plate, and the bullet that the upper strata was arranged when guaranteeing that lower floor's bullet is dialled can in time fall to the lower floor and fill the vacancy that the lower floor was dialled the bullet position to make all the time there is the bullet between each lower floor shift fork of driver plate, and then guarantee can not appear empty bullet phenomenon. When the driving plate rotates, the shifting fork pushes the projectile to move together, and when the projectile is shifted to the bearing, the projectile on the upper layer moves to the position above the separation blade with the separation blade cabin under the action of the shifting fork, the projectile on the lower layer and the bearing until leaving the separation blade of the cabin. The lower layer projectile receives the combined action of bearing, baffle and double-deck spiral driver plate shift fork and is impeld lower floor's exit channel, and the shift fork of double-deck spiral driver plate becomes the slope form to make the shift fork have a vertical decurrent component to the thrust of projectile, guaranteed that the shift fork can not produce two power balance phenomena to the effort of projectile and the effort of bearing to the projectile and cause the projectile card to die in bearing department and can't be stirred.
