According to a fourth aspect of the present invention, there is provided a configuration including a launch angle setting leg for holding a launch cylinder at a predetermined launch angle with respect to the ground. Means.

[0007]

In the land mine disposal apparatus according to the first aspect of the present invention, a fixed body provided coaxially at the tail of the launch tube is pierced into the ground so that the launch tube has a predetermined angle of incidence. This operation can be performed manually, and may be set to such an extent that the firing angle of the firing cylinder can be maintained when firing a towed bullet. In addition, the launcher is loaded with towed ammunition along with the pyrotechnics for firing, the towed ammunition is connected to one end of an explosive-packed bombshell, and the other end of the bombshell and the launcher are braked. They are connected by ropes.

[0008] In this state, when the firing pyrotechnic is operated and the towed bullet is fired, the recoil generated in the tail direction is applied to the launching cylinder and the fixed body, whereby the fixed body penetrates deeper into the ground and becomes an anchor. The fixed state of the launch tube is complete. Further, the fired towing bullets tow the explosion cord, and thereafter, the towing bullets and the explosion cord are braked by the brake cord, and the projection of the explosion cord is completed. At this time, in the mine disposal device, the launching cylinder is completely fixed by the recoil when the towing bullet is fired, so that the launching cylinder is not pulled out of the ground by the towing bullet and the explosion line, and The towing bullets and the explosion rope are normally braked by the connected braking rope.

Therefore, transportation and the like can be easily performed. In addition, since the initial setting is performed simply by piercing the fixed body into the ground so that the launch cylinder has a predetermined launch angle, the launch preparation can be made very easily and with a small number of people without being greatly affected by the soil properties. Can be done in time. Furthermore, the launch cylinder can be completely fixed by using the recoil when the towed bullet is fired, and the fixed body is cut into the ground, so that the launched towed bullet and the explosion can be used without using a separate anchor. The rope can be reliably braked and the explosion rope can be properly projected, and as a whole, the mine disposal can be significantly reduced in labor and speed.

According to the mine disposal device of the second aspect of the present invention, the same effects as those of the first aspect can be obtained, and the tail of the fixed body is pointed and the cross section of the fixed body is radial. By doing this, it is possible to more easily and reliably perform the piercing of the fixed body into the ground due to the recoil when the fixed body is pierced into the ground in the initial setting, and the recoil when the towing bullet is fired, and the launching in a direction other than the piercing direction. The predetermined angle of incidence can be maintained by preventing the movement of the cylinder.

According to the mine disposal device of the third aspect of the present invention, the same effects as those of the first and second aspects can be obtained, and also, in the radial direction of the launch cylinder between the launch cylinder and the fixed body. Because of the provision of the extending flange, in the initial setting, the operation of piercing the fixed body into the ground can be easily performed by pressing the flange with the hand or foot. Also, when the fixed body bites into the ground by the recoil that fired the towing bullet,
Excessive biting of the fixed body can be prevented by the flange, and when removing the launch tube, the work of removing the fixed body can be easily performed using the flange as a clue.

According to the land mine disposal device of the fourth aspect of the present invention, the same effects as those of the first to third aspects can be obtained, and in addition, the firing mine which holds the firing cylinder at a predetermined angle to the ground can be obtained. With the angle setting leg, in the initial setting, the launch tube can be set accurately without mistake of the firing angle, and when the tow bullet is fired, the launch tube may fall due to the recoil In addition to the prevention, the fixed body can be more reliably bite into the ground by maintaining the correct angle of incidence.
