ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a landmine release device that disperses and releases landmines from a discharge tube loaded with a plurality of landmines using the explosive force of the combustion gas pressure of a discharge agent contained in a discharge cartridge.

あつた。 Generally, landmines are laid underground, but in places where it is not possible to bury them directly underground, they may be dispersed from aerial vehicles. In such cases, mine release devices were used to disperse multiple landmines at once. Conventionally, as shown in FIG. 1, such a landmine release device has a structure in which the lower end of a discharge tube 1 loaded with a plurality of landmines G is supported by a lower stopper 4 having a shear pin 15a that supports the weight of the mines. At the same time, the upper end of the ejector tube 1 is sealed with an upper stopper 2 screwed onto the ejector cartridge 3 containing the ejected drug, and the mine is directly pressurized with the combustion gas pressure generated by the ignition of the ejected drug. It was configured to release the mine G outside the ejection tube 1 by cutting the shear pin 15a. However, in such a conventional release device, the combustion gas of the drug to be released leaks from the gap between the release cylinder 1 and the lower stopper 4, and the gas pressure is not effectively used to cut the shear pin 15a. However, there was a drawback that sometimes the shear pin 15a was not cut. Therefore, if a weaker shearing pin is used to prevent this, there is a risk that the shearing pin will be broken during handling such as loading a landmine. It is necessary to increase the combustion gas pressure in the cylinder. However, increasing the gas pressure not only causes recoil to the mine itself and the aircraft, but also requires increasing the strength of the ejector attachment device, which has a weight limit and poses operational problems. I was afraid. Furthermore, since the ejector cartridge is usually attached to the ejector immediately before flight of an aircraft, the conventional method in which the ejector cartridge is screwed onto the upper stopper of the ejector tube has the disadvantage that it takes time to attach the ejector cartridge.

のである。 Therefore, the present invention aims to solve the above-mentioned problems.The purpose of the present invention is to shorten the time required to attach the ejection cartridge to the ejection tube, and to make the operation easy with one touch. It is an object of the present invention to provide a landmine release device that can be loaded with landmines and also be able to release landmines from an aircraft without any trouble. An upper stopper is attached to accommodate the connected ejection cartridges, and a lower stopper is provided at the lower end of the ejection cylinder with a rotatable bottom ring having a shear pin on the circumference and a protrusion with a strong shearing force. In addition, an adapter having a button tip mechanism in which a steel ball fits into an annular groove drilled in the ejection cylinder is attached to the upper stopper, and the combustion gas of the ejected medicine is placed between the upper stopper and the ejection cylinder. This is characterized by the attachment of a prevention member to prevent loss of pressure.

A leakage prevention member is used to prevent loss of combustion gas pressure of the released medicine between the pressure plate 6 and the pressure plate 6. The leakage prevention member is, for example, an O-ring or the like, and is attached to the outer peripheral surface of the pressure plate 6 in this embodiment. Reference numeral 8 denotes an adapter that controls the function of attaching the ejection cartridge 3 to the upper stopper body 2 with a single touch;
It is constructed as a so-called button tip mechanism consisting of a steel ball 10, an outer cylinder 11, and a compression spring 12.

On the other hand, the lower end is locked at the middle part of the inner surface of the outer cylinder 11, and a force is always applied to the outer cylinder toward the lower part in the axial direction in the drawing. Reference numeral 14 denotes a retaining ring for positioning the outer cylinder, and the retaining ring is attached to the outer peripheral surface of the inner cylinder 9 in the lower direction.
This is to stop the button from being pressed downward. The adapter 8 is held in a screwed state with the upper stopper 2.

Notches 4a and 4b are provided. This notch 4a is cut out so that a shear pin 15a (described later) passes through it, while the notch 4b is cut out so that a shear pin 15a (described later) passes through it, while the notch 4b has a projection 15b.

へ地雷Gが放出散布される。 An example of the device for carrying out the present invention is constructed as described above, and its operation will now be explained. First, the discharge tube 1 shown in FIG. 2 is reversed, and the bottom ring 15 attached to the lower stopper body is removed. After that, load multiple mines G from above. Then bottom ring 1
5 is inserted after the shear pins 15b and protrusions 15a on the outer peripheral surface of the bottom ring are aligned with the notches 4a and 4b of the lower plug body 4, respectively, as shown in FIG. Thereafter, the operating handle 16 is rotated so that the protrusion 15b supports the weight of the mine G.
In this state, the ejection cylinder 1 is turned upside down to take the normal position shown in FIG. It is normally stored in this state and transported to an aircraft. Now, when attempting to scatter and drop land mines G on the ground from an aircraft, it is necessary to load the discharge cartridge 3 into the discharge tube 1. In this case, as shown in FIG. 3, when the outer cylinder 11 of the adapter 8 is first pulled upward, the lower end surface of the outer cylinder is notched in a diverging shape, so the steel ball 10 separates from the tapered hole groove 9a of the inner cylinder 9. and can move freely. Thereafter, the cartridge 3 is pushed in from above the adapter 8 and loaded, and the state in which the outer cylinder 11 is pulled upward is released. Then, the steel ball 10 is fitted into the annular groove 3a of the discharge cartridge 3 by the restoring force of the compression coil 12 and is fixed. Next, just before releasing the mine G from this state, the handle 16 of the bottom ring 15 is rotated so that the protrusion 15b is aligned with the notch 4b of the lower stopper 4, and the shear pin 15a supports the mine's own weight. I'll do what I do. Thereafter, the discharge cartridge 3 is connected to the igniter. In this way, release cartridge 3
When the discharge charge contained in the mine G is ignited, the combustion gas pressure destroys the bottom of the discharge cartridge 3 and burns in the combustion chamber in the space of the pressure plate 6, and this combustion gas pressure causes the mine G to be propelled toward the bottom. push. As a result, the shear pin 15b is cut by the pressing force of the mine G, and the mine G is ejected and scattered outside the ejection tube 1.

A prevention member is installed to prevent the loss of the combustion gas pressure of the released mine, and the mine is supported by its own weight and a shear pin only immediately before the mine is released, so compared to conventional landmine release devices, the amount of released medicine is reduced. The tube can be loaded extremely easily and in a short time with one touch, the mines can be handled and stored safely, and the mines can be reliably released from the aircraft without any problems.
