Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an antipersonnel landmine disposal machine that can efficiently and safely process antipersonnel landmines.
[0002]
[Prior art]
Various types of anti-personnel landmine disposal machines have been proposed in the past. For example, Patent Document 1 discloses an endless track vehicle in which a front structure for mine sweeping is provided at the front of a work vehicle.
[0003]
FIG. 5 is a side view showing the configuration of the front structure. In FIG. 5, a front structure 70 is attached to a front end portion of a frame 62 that is swingably attached by a hydraulic cylinder 61 in front of the work vehicle 60. The front structure 70 includes a box 71 that opens forward and downward, a milling drum 72 that is rotatably provided in a direction transverse to the traveling direction, and a protective shield at the front end of the box 71. And a flap plate 74 provided to be swingable. A cutting and crushing tool 73 is attached to the outer peripheral portion of the milling drum 72, and the milling drum 72 can rotate forward and backward.
[0004]
In the landmine sweeping operation, as shown in FIG. 5, the milling drum 72 should be rotated in the opposite direction (arrow direction) while the work vehicle 60 is moved forward, and the pedestal 62 should be pushed down to search for the landmine. The cutting and crushing tool 73 is cut into the ground. At this time, the flap plate 74 is fixed in a state of being inclined forward, that is, protruding upward. The landmine 81 is captured by the cutting and crushing tool 73 and is exploded by the pressure applied to the landmine 81 in the earth and sand 80 sent in front of the milling drum 72. If necessary, the front end of the box 71 can be covered by lowering the tip of the flap plate 74. As a result, the flap plate 74 functions as a protective shield, and it is possible to effectively avoid the scattering of fragments. Further, landmines that are not exploded by rotating the milling drum 72 in the traveling direction are carried out of the box 71 or the area of the milling drum 72 (see, for example, Patent Document 1).

[Problems to be solved by the invention]
However, the above configuration has the following problems.
Landmine debris remains in the earth and sand because it detonates and moves as it is in the excavated earth and sand. Also, landmines that are not exploded by the rotation of the milling drum are discharged out of the box or milling drum area by reversing the rotation of the milling drum. These debris and unprocessed landmines must be collected again in a separate process, transported to a safe place, etc., and processed, which requires a great deal of man-hours.
Landmines are supposed to explode due to the pressure of earth and sand, but if the pressure due to earth and sand is low, the landmines may not explode. Further, since the milling drum is rotated in the direction opposite to the traveling direction, the mine is dug up, and there is little opportunity to hit the mine, and the mine may not be exploded or destroyed, and the reliability of the processing work is low.
[0007]
The present invention has been made paying attention to the above-mentioned problems, and an object of the present invention is to provide an antipersonnel landmine disposer having a processing structure capable of processing an antipersonnel landmine efficiently, reliably and safely.

A work machine 10 that processes antipersonnel mines is attached to the front end of the vehicle body 3. The work machine 10 is pivotally attached to the vehicle body 3 by a pin (not shown) at the base end, and can swing up and down by a hydraulic cylinder 7 attached to the vehicle body 3. The work machine 10 includes a rotor 11 disposed in the left-right direction of the self-propelled vehicle 2, and a box-shaped rotor cover 20 that covers the rotor 11 and that opens forward and downward. A plurality of bits 13 are attached radially to the rotor shaft 12 of the rotor 11. The rotor shaft 12 is rotationally driven by a rotor driving device 14 attached to the rotor cover 20, and the rotor shaft 12 can rotate in the same direction (arrow direction) as the traveling direction of the self-propelled vehicle 2. A basket 30 is provided at the front end of the rotor cover 20 to capture mine fragments and unprocessed land mines. Also, a warming-type chain 41, which is an example of a protective member 40 that prevents scattering of landmine fragments, earth and sand, and the like, is attached to the lower portion of the rear end.
[0020]
FIG. 2 is a side view of the work machine 10, and FIG. 3 is a plan view. The same members as those in FIG. 1 are denoted by the same reference numerals and description thereof will be omitted, and only different portions will be described. 2 and 3, the rotor cover 20 is formed in a box shape from a rear plate 21, an upper plate 22, and a pair of left and right side plates 23, 23, with a front opening 24 at the front and a lower opening at the bottom. 25. A swash plate 26 is provided in the rear part of the rotor cover 20 to form a rotor chamber 27. Repellent plates 28 a and 28 b are fixedly provided on the lower surface of the upper surface plate 22 and the lower portion of the swash plate 26 on the rotor chamber 27 side. The repulsion plates 28 a and 28 b are provided over the entire width between the left and right side plates 23 and 23. A basket 30 is disposed in front of the front opening 24 of the rotor cover 20. The basket 30 is a net-like box having an opening 31 on one side, the opening 31 is opposed to the front opening 24 of the rotor cover 20, and one side 32 of the opening 31 is pinned to the upper surface plate 22 of the rotor cover 20. 33, 33 and 33 are rotatably supported. The width of the basket 30 is set slightly larger than the interval between the left and right side plates 23, 23. Therefore, the front opening 24 of the rotor cover 20 is covered with the basket 30. The basket 30 is connected to the rotor cover 20 by hydraulic cylinders 35, 35 which are an example of the opening / closing drive means 34, and is rotated and opened as shown by a two-dot chain line a by reducing the hydraulic cylinders 35, 35.

[0021]
FIG. 4 is a side cross-sectional view for explaining the antipersonnel landmine disposal work by the work machine 10. In FIG. 4, while the self-propelled vehicle 2 (not shown) is moved forward, the rotor 11 is rotationally driven in the direction of the white arrow that is the same as the traveling direction, the work machine 10 is pushed down by the hydraulic cylinder 7 shown in FIG. Cut down to the surface GL. Antipersonnel mines buried in the ground (not shown) are buried deeper by the bit 13, and at the same time, the fuze is hit and destroyed. Explosions occur in deep soil, so there is little impact on the surroundings. Those that do not explode are also struck by the bit 13 and destroyed. The land mine that did not explode or the anti-personnel land mine 50 that was not sufficiently destroyed is lifted by the bit 13 as shown in the figure, and collides with the first repulsion plate 28b to be destroyed. Even if this is not sufficiently destroyed, it moves in the rotor chamber 27 and collides with the second repulsion plate 28a to be destroyed. The broken pieces or the landmines 51 that have not been exploded are discharged to the front of the rotor cover 20 and pass through the front opening 24 and the opening 31 of the capture basket 30 and are put into the basket 30. The mine fragments exploded in the ground are swept up by the bit 13 and put into the basket 30. Landmines or debris in the basket 30 are transported to a predetermined place, where the hydraulic cylinder 35 is reduced to open the basket 30 to a position indicated by a two-dot chain line, and the contents are dropped. During the operation, earth and sand and debris splashed backward by the bit 13 are stopped by a warm chain 41 provided at the lower end of the rear end of the rotor cover 20 and are not scattered toward the self-propelled vehicle 2 (not shown).
[0022]
Since the antipersonnel landmine disposer of the present invention has the above-described processing structure, the following effects can be obtained.
Since the basket is provided in the front opening part of the rotor cover, it is possible to capture mine fragments in the earth and sand, unprocessed landmines released to the front of the rotor cover without being crushed. Therefore, it is possible to blast and destroy mines with a rotor, collect and capture debris with a basket, transport them with a self-propelled vehicle, and complete a series of antipersonnel landmine disposal operations in one process, thus improving work efficiency. Can be improved. In addition, since the opening / closing drive means for opening and closing the basket is provided, the dropping operation of the fragments in the basket can be performed easily and safely.
Since the repellent plate is provided in the rotor cover, when the mine passes through the rotor cover and is sent forward, it collides with the repellent plate, so that the destruction is promoted and the mine treatment can be ensured and reliable. The degree is improved.
