Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tree transplanting method used for transplanting trees at the time of construction or remodeling work at golf courses, resort areas, parks, etc., and a self-propelled engine for direct use thereof. The present invention relates to a tree transplanting device.

[0002]

2. Description of the Related Art As a preparation process for conventional tree transplanting work,
Before excavating the root part, use a power shovel etc. in advance to dig a root cutting groove around the root part of the tree as shown in Japanese Examined Patent Publication No. 1-50368 to cut the root branch protruding into the surrounding soil and then use a conventional tree transplanting machine. It was Tsu Monogaa to digging roots using.

Further, Japanese Utility Model Publication No. 1-26210 is equipped with a water discharge pipe with planting after backfilling and transplanting trees to be transplanted into a planting hole.
There is a type that can supply water even to the lower surface of the root part of a tree by supplying water of about / cm ² and makes the survival of the tree good.

[0004]

However, in order to dig the root-cutting groove, an earthmoving machine such as a power shovel must be kept on standby at the site separately from the tree transplanting machine. Machine rent cost is required. Therefore, it is conceivable to omit the excavation of the root cutting groove and excavate the root part at once with a tree transplanting machine, but in that case the root branch around the root part is compressed and cut, and it is split and the cut surface is finely split. After transplanting and implanting, the root rots in the area and the vigor is weakened, resulting in poor rooting and withering after transplantation.

Furthermore, it is difficult to directly insert the right and left shovels into the soil to the required depth without the root cutting groove, because the soil pressure resistance and the soil friction resistance prevent the progress of the work.
This is especially true on firm ground.

[0006] The main cause of these is that the left and right shovels of the conventional tree transplanting machine are directly hung and pivoted to the frame body such as a U-shaped plane or the like so that the rotation center is one fixed center and there is no freedom of movement. Since only a small rotary arc motion that draws a locus is generated, it unnecessarily induces a compressive effect on the soil, which increases the piercing friction resistance into the ground and the root digging up friction resistance in the ground. This is because the blades for cutting branches and special equipment are not equipped with right and left shovels.

Further, depending on the tree transplanting machine, it is necessary to prepare two models for large trees and small trees due to the structure of the front opening width of the tree transplanting device. Here, the present invention is to provide a tree transplanting method and a tree transplanting apparatus for a self-propelled engine that can perform root digging work of a tree quickly and smoothly.

(Example of Method) Now, the construction procedure when the tree transplanting method of the present invention is applied to the tree transplanting apparatus for a self-propelled engine shown in FIGS. 1 to 3 will be described. First, the self-propelled engine A is advanced to the rear side of the target tree α, and the left and right lever plate operating cylinders 29 and the left and right excavator operating cylinders 33 are appropriately operated to move the left and right excavators 24 to the left and right claw blades 38 toward the ground G. As shown in FIG. 2, when the target tree α is moved forward so that the target tree α is gradually inserted into the plane U-shaped frame body 18 from the opening front side, the jet water jet pipes 40, 40 are passed through the left and right jet water supply pipes 24, 24, respectively. Water pressure 75kg / cm ²
The above high-pressure jet water is jetted to make incisions in the ground G on both sides where the left and right shovels 24 around the target tree α are inserted. At that time, the self-propelled motor A can be repeatedly moved forward and backward and forward and backward to deepen the cut, or the water pressure can be increased to cut the root branch group.

Next, the left and right excavator 2 are operated by appropriately operating the left and right elevating and lowering operation cylinders 9, the left and right lever plate operation cylinders 29, and the left and right excavator operation cylinders 33 of the elevating and hoisting mechanism B.
The triangular claw blades 38 of No. 4 are carved with high-pressure jet water and pierced into the softened notches containing water, but the piercing friction resistance into the ground is reduced as much as possible and the smooth left and right shovel 24 Intrusion into the ground to the required depth.

After that, the left and right lever plate operating cylinders 29 and the left and right shovel operating cylinders 33 are appropriately operated, and the left and right shovels having a large degree of freedom by the two rotation centers of the pivotal support shaft 22 of the fixed center and the pivotal support shaft 25 of the movable center. At the time of root excavation accompanied by the close-closed movement of 24, a large rotary arc motion is generated to avoid the compressive action on the soil and root β as much as possible, and the root excavation friction resistance is minimized. The lower part β of the right and left shovels 24 smoothly invades while being kept small. At that time, the left and right triangular claw blades 38, which come into contact with the group of root branches, can be cut neatly and neatly, further weakening the frictional resistance.

Subsequently, the left and right elevating and lowering operation cylinders 9, the left and right elevating and lowering operation cylinders 13, and the seat operation cylinders 49 of the elevating and undulating mechanism B are appropriately operated to erect the tree seats 46, thereby hitting the back side of the tree α. After receiving and holding, the left and right undulation operation cylinders 13 cause rearward tilting movement of the entire tree transplanting device C, and the tree α transplantation device 9 itself is inclined by the left and right elevating operation cylinders 9 by inclining the center of gravity of the tree α backward. To move up and down to dig up the root β.

Further, the seat operating cylinder 49 is appropriately operated to rotate and tilt the tree seat 46 rearward to largely tilt the tree α and move the center of gravity closer to the center of gravity of the self-propelled motor A, and While maintaining the posture of the tree transplanting device C as it is, the self-propelled main engine A is driven to run, and the tree α is moved to the place where the tree α has been excavated in advance. Unlike conventional upright transportation, the self-propelled motor A is not able to drag the left and right shovels 24 due to the front squeezing phenomenon or seesaw traveling during normal driving, and can achieve normal balance traveling that is planned. There is no occurrence of a rollover accident of the type A prime mover.

Furthermore, the tree transplanting device C is brought over the planting hole, and the lifting operation cylinder 9 and the undulation operation cylinder 13 are provided.
Is appropriately actuated to lower the tree transplanting device C to a required height and at the same time returned to the horizontal posture, the seat operating cylinder 49 is appropriately actuated to erect the tree seat 46, thereby vertically erecting the tree α, The left and right lever plate operating cylinders 29 and the left and right shovel operating cylinders 33 are appropriately operated to open the left and right shovels 24 to the left and right by the anti-separation opening operation to release the under support, and the root part β is gently dropped to the bottom of the implantation hole to set it down. The run-back prime mover A is retracted, and the backfill transplantation work is completed.

In the embodiment of the present invention, the shell type shovel 24 is adopted, but a bucket type shovel may be used in the case of sandy land, or jet water jet is embedded and opened at the tip of the triangular claw blade group 38. The number of nozzles 40 and the position of the triangular claw blades 38 to be attached do not matter.

In short, according to the method of the present invention, a jet water jet nozzle 40 is provided at the tip of the shovel 24,
It is easy to pierce the ground G around the root α of the tree α that is pierced with the water. And at least one movable center is provided to act at the same time or individually when excavating, which causes a large circular arc motion to pierce the ground and the root resistance in the ground. The excavator 24 is directly excavated by omitting the preliminary root cutting trench excavation around the tree α root part β by making the size smaller.

[0025]

As described above, according to the present invention, since the root cutting groove can be omitted in advance, the civil engineering machine such as a power shovel and the manpower required therefor can be greatly reduced, and the solid water is preliminarily changed from the jet water jet nozzle. Shaving with high-pressure jet water, stab the left and right shovels into the soft cuts containing water, and cause a large rotary arc motion at at least two centers of the fixed center and the movable center to maximize the compression effect on the soil. Avoid it and reduce the friction resistance of the right and left shovels into the ground and the root excavation friction resistance in the ground as much as possible. Keeping the vitality after transplantation without cutting, streamlining work,
