[0003]

The conventional artillery bullet feeder has the following problems because it is constructed as described above. That is, since a duct having a flexible configuration is used, when an ammunition having a large caliber and a heavy weight is to be sent, the flexible portion is largely bent, and there is a fear of breakage. In addition, trying to eliminate this deflection would result in a loss of flexibility, making it difficult to turn following the cannon's elevation and hindering the firing. Also, this flexible portion 6a
Must connect and assemble a large number of very complex duct pieces, as shown in particular in FIGS.
It has been extremely difficult to reduce manufacturing costs. In addition, since the duct has a flexible structure, it is impossible to avoid the existence of gaps, it is difficult to prevent gas at the time of firing from entering the turret, and it is necessary to prevent the operator from receiving the fired gas. It had to be designed so that the bulkhead or operator could be located in a safe position and the cannon could be located outside the turret. Further, as shown in FIG. 9, since the engine section of the cannon was provided at the rear position of the turret shaft support section, when the machine gun was lowered, as shown by the dotted line, the engine section was on the ground or the gantry. It is necessary to raise the height of the turret and raise the position of the turret shaft support in order to prevent contact with the gun. It was difficult to mold.

The present invention has been made to solve the above problems, and in particular, a duct is connected to a position in front of a turret shaft support of a cannon to reduce the height of the cannon unit itself. It is an object of the present invention to provide a cannon apparatus in which the structure of the duct is simplified by providing a bullet feed shaft support portion in the duct and supporting the duct while reducing the size thereof, and a bullet feed apparatus therefor.

[0005]

According to a first aspect of the present invention, there is provided a cannon apparatus and a bullet feeding apparatus for the cannon, wherein the cannon is provided by a turret shaft support of the turret so as to be capable of raising and lower, and the ammunition from the ammunition box is passed through a duct to the gun. In a cannon device configured to send bullets from a side, the duct is connected to a front portion of the cannon located forward from the turret shaft support portion,
An engine unit is not provided at a rear portion of the cannon located rearward from the turret shaft support portion. Further, in the bullet feeding device of the cannon device according to the present invention, the cannon is provided so as to be able to be raised and lowered by the turret shaft support of the turret, and the ammunition from the ammunition box is sent from the side of the cannon via the duct. In the bullet feeding device of the cannon device, a bullet feeding shaft support provided in the duct connected to the side portion of the cannon is provided, and the duct is configured to be raised by the bullet feeding shaft support. A first half cylinder connected to the duct;
The second semi-cylindrical body connected to the ammunition box constitutes the bullet feed shaft support, and the respective half cylinders are slidably connected to each other so that the ammunition passes through the bullet feed shaft support. In the duct and the bullet feed shaft support portion, a con bearing that is formed by connecting a large number of semi-cylindrical feed pieces in an operable state via a shaft support portion is movable. And the ammunition is placed on the bomb and sent, and the cannon and the duct are simultaneously lowered at the same angle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a cannon apparatus and a bullet sending apparatus according to the present invention will be described below with reference to the drawings. The same or equivalent parts as those in the conventional example will be described using the same reference numerals. In FIG. 1 and FIG. 2, a reference numeral 1 denotes a cannon. The cannon 1 is configured to be able to move up and down in directions of arrows A and B by a turret shaft support 3 provided on a pair of turrets 2. .

A duct 6 formed of an inflexible material and bent in an arc shape is connected to a side portion of the cannon 1. The duct 6 is configured to be lowered in the directions of arrows A and B by the bullet feed shaft support 8 in the same manner as the cannon. The engine unit 4 of the cannon 1 is provided between the mounting position of the duct 6 and the turret shaft support 3, and the equipment of the cannon 1 is not particularly provided behind the turret shaft support 3.

As shown in FIG. 7, a first and a second half cylinders 20 and 21 having different diameters are slidably connected to each other in the bullet feed shaft support section 8, and a cylindrical body guide 22 has a side wall 23 at the center thereof. It is fixedly arranged by. A large number of semi-cylindrical feed pieces 30 as shown in FIG. 6 are operably connected by a shaft support 31 in a bullet feed passage 24 formed by the duct 6 and the feed shaft support 8. A con bearing 32 shown in FIG. 3 is movably provided.
The ammunition 35 is arranged and transported. The con bearing 32 is configured to be able to move endlessly between the ammunition box 7 and the cannon 1, and the ammunition 35 is automatically placed on the bullet 30 in the ammunition box 7.
Is configured to be supplied.

Next, the operation will be described. First, in the case of FIG. 4, since the elevation angle of the cannon 1 is 0 °, when the cannon 1 is operated in this state, the ammunition 35 is sequentially sent and fired in a horizontal state. When the elevation angle of the cannon 1 is set to about 45 ° as shown in FIG. 5, the cannon 1 and the duct 6 are simultaneously interlocked through the turret shaft support 3 and the bullet feed shaft support 8 to about 45 °.
It can be raised and act like a flak. In addition,
In this case, since the duct 6 is a hard material that does not deform,
As the cannon 1 moves, it lowers at the same time.

Next, as described above, since the machine gun 1 according to the present invention does not have any special equipment provided behind the turret shaft support 3 of the machine gun 1, as shown in FIG. 9, the length A of the cannon 1 is significantly shorter than that of the conventional configuration of FIG. 9, there is no obstruction at the time of elevating, and the length B between the duct 6 and the rear end is also significantly reduced. By comparison, their height can be significantly reduced.

[0011]

As described above, the cannon apparatus and the bullet sending apparatus according to the present invention have the following effects. That is, since the duct provided on the side of the cannon is located in front of the turret shaft support and the engine is not provided behind it, the overall height can be reduced and the size can be reduced. In addition, since the duct and the ammunition box are connected by a rotatable bullet support, the duct itself does not bend and does not need to be made of a flexible material as in the past, and can be configured with a hard duct. Large ammunition can be sent freely.
