SUMMARY OF THE INVENTION An automatic bullet feeding device for a combat vehicle according to the present invention is intended to solve the above-mentioned problems, and is formed by a groove of two roller guides arranged in parallel via a guide roller. Ammunition holders supported at both ends and pulled by a cord mounted between two shafts, which are supported by the roller guides at a distance from each other and are axially supported at both ends, and are fed laterally along the roller guides. In the automatic bullet feeder of the combat vehicle for performing the above, the roller guide between the two shafts is provided with the divided portion where the groove end portions of the roller guide are formed in a concavo-convex pattern, and the roller guide is engraved on the roller guide. And a cutout portion that communicates with the groove.

[0005]

That is, in the automatic bullet feeder of the combat vehicle according to the present invention, the ammunition holder is supported at both ends via the guide rollers by the grooves of the two roller guides arranged in parallel and by the roller guides. It is designed to be pulled by a rope suspended between two shafts that are axially supported at a distance from each other and fed laterally along the roller guides to feed bullets. A split portion is provided, the groove ends of the guide rollers are formed in a concavo-convex shape, and a cutout portion that communicates with the groove of the roller guide is engraved in the roller guide. The two axes of the roller guide are separated from each other at the split portion. Even if the rope is tensioned by sliding it in the direction, the groove ends of the roller guides form a concavo-convex pattern at the split parts, so there is no gap on the rolling surface of the guide roller, and the roller guide roller Since notch leading to a groove of the id is inscribed can be removed and installed only ammunition holder required to move the ammunition holder until notch of the roller guide.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 and FIG. 2 are structural explanatory views of an automatic bullet feeder according to an embodiment of the present invention. In the figure, an automatic bullet feeder according to the present embodiment is used for loading bullets in a combat vehicle. Reference numeral 1 is an ammunition holder, 1a is a guide roller attached to both ends of the ammunition holder 1, and 2 is a drive. axis,
Reference numeral 3 is a driven shaft, 2a and 3a are sprockets, 4 is an endless chain suspended between the sprockets 2a and 3a, and 5 is a plate fixed to the cutout portions of the roller guides 6 and 7. The cutouts of the roller guides 6, 7 communicate with the roller groove 1b formed in the roller guides 6, 6 ', 7, 7'. The ammunition holder 1 is fitted into and supported by the roller groove 1b via the guide roller 1a. The roller guides 6, 6 ', 7, 7'are divided at the dividing portion IIb to give tension to the endless chain 4 by tension adjustment. The roller guides 6, 6'located at the front of the ammunition are fixed to the front plate 8, and the roller guides 7, 7'located at the rear of the ammunition are fixed to the drive unit 10 and a bracket (not shown). Roller guides 6, 6 ',
The divided portions IIb of 7 and 7'are combined with each other by providing irregularities 1c at the ends of the roller groove 1b. 11 is a turret, 1
Reference numeral 1a is a passenger compartment, and 11b is an ammunition compartment (magnification area). The front plate 8 also serves as a partition wall for the passenger compartment 11a and the ammunition compartment 11b, and together with the base frame 9 forms the main frame of the present apparatus. Incidentally, in FIG. 1, the ammunition holder 1
Are not shown.

When the drive unit 10 is rotated, the rotation is transmitted through the drive shaft 2 and the sprocket 2a to the endless chain 4
And the ammunition holder 1 attached to the endless chain 4 at equal intervals is laterally fed along the roller guides 6, 6 ', 7, 7'. If the endless chain 4 stretches, the roller guides 6 ',
Slide 7'to the outside to adjust the tension. When mounting the ammunition holder 1, the plate 5 is removed from the notches of the roller guides 6 and 7, and the guide rollers 1a of the ammunition holder 1 are fitted into the roller grooves 1b from the notches of the roller guides 6 and 7 to form an endless chain. 4 is fixed to the ammunition holder 1. To remove it, reverse this procedure.

When assembling this apparatus, first, the drive shaft 2, the driven shaft 3, the roller guide member 6, and the drive unit 6 are included.
6 ', 7, 7', etc. are attached to the front plate 8 and the base frame 9. Next, the endless chain 4 is suspended between the sprockets 2a, 3a of the drive shaft 2 and the driven shaft 3 to connect both ends. Next, the guide rollers 1a of the ammunition holder 1 are fitted into the roller grooves 1b of the roller guides 6, 6 ', 7, 7'through the notches of the roller guides 6, 7 to fix the endless chain 4 to the ammunition holder 1. Then, in order to apply tension to the endless chain 4, the driven shaft 3 is moved outward together with the roller guides 6'and 7'to widen the sprocket 2a, 3a between the drive shaft 2 and the driven shaft 3. Even if the roller guides 6'and 7'slide outward, since the end portions of the roller groove 1b of the roller guide dividing portion IIb are combined with each other by providing the unevenness 1c, a gap is formed on the rolling surface A of the guide roller 1a. Does not happen.

As described above, in this apparatus, the ammunition holder 1 is connected to the endless chain 4, and the guide rollers 1a provided at both ends of the ammunition holder 1 are roller guides 6, 6 ', 7 ,.
By rolling the roller groove 1b of 7 ', the ammunition holder 1 automatically and smoothly carries out ammunition at the loading position without fine movement in the front-rear direction or the left-right direction. Even if the endless chain 4 is adjusted by moving it to the outside, no gap is created on the rolling surface A of the guide roller 1a, so that the guide roller 1a of the ammunition holder 1 rolls smoothly and the ammunition has a smooth lateral movement. When a feeding operation is performed and a problem occurs in any of the ammunition holders 1, the ammunition holder 1 is moved to the cutout portions of the roller guides 6 and 7 to easily remove only the ammunition holder 1. Can be installed.

[0010]

The automatic bullet feeding device for a battle vehicle according to the present invention is constructed as described above, and since there is no gap on the rolling surface of the guide roller, the bullet feeding is automatically performed smoothly.
Further, since only the necessary ammunition holder can be detached or attached, even if a malfunction occurs in any of the ammunition holders, it can be easily replaced.
