Japanese Patent No. 3096847

As shown in FIGS. 7 and 8, a heavy machine vehicle (base machine) 1 used for shovels such as backhoes, which is currently most frequently used in the market, is used, and the heavy machine vehicle 1 has an undulating and refractable arm. 2 is provided. 3 is the driver's seat (cabin) and 4 is the track for driving.

The undulating and refractable arm 2 is composed of a boom 2a, an arm 2b, a boom cylinder 2c, an arm cylinder 2d, and a bucket cylinder 2e, and the holding interval of the pin 6 on the attachment side is variable at the tip of the link mechanism 5a. An attachment attachment / detachment device 5 incorporating a screw handle type slide mechanism 5b is provided.

Of the windowpanes of the driver's seat 3, special bulletproof glass (Rexguard) 7 is used for the windshield to ensure safety.

As an attachment to be attached to the tip of the undulating and refractable arm 2 via an attachment attachment / detachment device 5, a cutter holder 13 is welded to the peripheral surface of the rotating drum 10 and carbon steel is made of a material via the cutter holder 13. It is based on the rotary cutter 9 in which the cutter bits 11 are planted at appropriate intervals.

The rotary cutter 9 is a type directly connected to a hydraulic motor, and the drive motor 12 is connected to the rotating shaft of the rotating drum 10 on the left and right, and about two-thirds is housed in the hood 24, the lower side protrudes, and the depth is at least about 30 cm or more. It can cut up to about 50 cm.

Further, as shown in FIGS. 9 and 10, the rotary cutter 9 provides a movable comb blade grapple 26b with a cylinder 26c to the fixed comb blade rake 26a to provide a rake grapple 26 capable of pinching operation. It was projected to the side.

In the figure, 28 is a fertilizer or soil conditioner sprayer attached to the rotary cutter 9, and hoses 28b connected to the discharge nozzle are provided below the horizontally long hopper 28a at appropriate intervals.

Next, the demining and farmland improvement performed by using such a demining and farmland forest improvement device will be described. Regarding the demining, as shown in FIGS. 11 and 12, the rotary cutter 9 is used for shrubs, reeds and grass. It can be easily processed by moving while turning from the side.

However, if it is expected that there will be trip wire mines hidden in the vegetation and unexploded ordnance, and it is difficult to see before the work, safety will be ensured by stepwise work. Even if the rotary cutter 9 touches a trip wire land mine or the like, not only the safety inside the driver's seat (cabin) 3 is ensured, but also the cutter portion and the main body are structured to withstand it.

The first step is to cut the vegetation at a height of 30 to 50 cm above the ground so as not to touch the unexploded ordnance. After this, check for unexploded ordnance on the ground. If an unexploded ordnance is found, it can be safely scooped up manually or by using the rake grapple 26 on the side of the rotary cutter 9, removed behind the machine body, and then manually transported and processed.

In the second stage, the vegetation is cut to 0 to 10 cm or less so that the subsequent detection work can be easily performed. As shown in FIGS. 13 and 14, when the cut vegetation is accumulated at a height of 10 cm or less on the ground or the shrubs have fallen high, the rake grapple 26 on the side of the rotary cutter 9 is used. Eliminate this. Trees with a height of 20 cm or more affect the detection work if the interval is narrow, but there is no problem if the interval is 10 cm or more, so use this as a guide to cut and remove obstructive objects. Trees with high height are cut in two stages, and collapsed trees are eliminated using a rake grapple 26.

Regarding the treatment of anti-personnel land mines, the location of the anti-personnel land mines revealed by the detection work will be emphasized, and all areas will be cleared by the rotary cutter 9 to treat the anti-personnel land mines.

In the processing work, as shown in FIG. 15, the bottom surface of the guide of the rotary cutter 9 is turned while being in contact with the ground surface so that the cutting edge of the rotary cutter 9 reaches the underground. Depending on the hardness of the land and the unevenness of the ground, the turning speed is changed and a sufficient depth is secured by two-step work.

As with the detection work, overlap 5 to 10 cm so that there are no unprocessed parts. Antipersonnel landmines are exploded by the high-speed rotation of the rotary cutter 9.

In demining, each work of "weeding-detection-treatment-confirmation" is carried out step by step so that there is no residual landmines by reliable treatment work, but farmland forest improvement is "wasteland" without landmines, "abandoned farming" The "ground" can be rotated and excavated at once using the highly efficient rotary cutter 9. Vegetation on the ground is cut by strong destructive force and is caught in the soil by rotation. The depth of one excavation is about 30 cm for continuous work. In some cases, it can be excavated twice and up to about 50 cm. After that, by reverse rotation using the same rotary cutter 9, uneven land is leveled by demining and excavation, and the improvement of the entire target area including demining is completed.

Similar to the demining system, a rotary cutter 9 is used to cut vegetation at a height of 30-50 cm above the ground. Then, the vegetation is cut to 0 to 10 cm or less.

For shrubs, debranching was performed using a rotary cutter 9 as shown in FIG. 16, and for fallen shrubs, a rake grapple 26 on the side of the tally cutter 9 was used to eliminate the fallen shrubs. To do.

The rake grapple 26 of Patent Document 1 is difficult to grasp such as a large tree.
