Description

[Detailed Description of the Invention] Industrial Application Fields This invention relates to a tree transplanting device, and in particular to a tree transplanting device in which the toes of the left and right scooping plates are opened and closed in a nearly horizontal trajectory. This device has been improved so that the left and right scooping plates can be swung up and down in a substantially horizontal state using telescoping drive means.

Conventional technology> The work of transporting trees basically involves digging up the tree, moving the dug up tree to the desired location, and replanting the moved tree in the desired location. .

Of course, in this case it is important not to damage the roots of the tree, and to avoid applying unnecessary external forces to the roots, for example, the roots should not be torn off or the soil surrounding the roots should be separated from the roots and fall off. You must make sure that you do not do it.

For example, what is shown in Figures 3 and 4 is
This is disclosed in Japanese Patent No. 68, in which an elevating mechanism 7 is attached to a body 5 on a traveling device ll such as a crawler, and a digging device 6 is attached to this elevating mechanism 7.

The digging device 6 includes a pair of left and right support rods 9 that are attached to the frame 8 that is raised and lowered by the lifting mechanism 7, and a pair of support rods 9 that rotate at least at the front and back of the upper and lower portions of the support rods 9, respectively. Links 21 and 22 attached movably
A pair of left and right scooping plates 1o are rotatably attached to the outer ends of the links 21 and 22 at the upper end and an inner part slightly lower than the upper end, and a hydraulic cylinder 23 opens and closes the scooping plates 10. The scooping plate 10 is gently curved inward so that the knife-edge-shaped toe 24 at the tip traces a nearly horizontal trajectory from the fully open position to the fully open position of the scooping plate 10. This is what I did.

In this conventional technique, as shown in FIG. 4, grooves l are formed in advance on the ground on both sides of the target tree, and the left and right scooping plates 1o are opened by the action of a cylinder 23, with their toes 24 facing downward. Both scooping plates 10 are inserted into the left and right grooves 1, and then the cylinder 23 is operated to cut the toes 24 of the two scooping plates 10 into the lower surface of the root of the tree to cut the roots, and then the lifting mechanism 7 to lift the tree and move it to the desired location.

<Problems to be Solved by the Invention> The above-mentioned conventional technology has advantages in that, compared to previous devices, it is easier to cut the roots at the bottom of the base, and the tree can be lifted in a stable state. However, the problem of this invention is to improve the above-mentioned conventional technology so as to be able to more reliably cut the roots at the bottom of the tree and to prevent unnecessary root cutting. The purpose of the present invention is to provide a transfer device.

<Means for Solving the Problems> In order to solve the above-mentioned problems, the present invention has been proposed to improve the outer side of the pair of left and right scooping plates of the digging device used in the above-mentioned prior art and the upper outer side of the above-mentioned support rod. The link connecting the ends is a telescoping link made of telescoping drive means such as a hydraulic cylinder, and the telescoping link allows both scooping plates to be swung up and down in a substantially horizontal state.

For cutting> This invention has the above-mentioned structure, and this device is used after trenches are previously dug on both sides of the tree and the roots extending laterally of the tree are cut.

First, open the left and right scooping plates of the digging device and move them onto the left and right grooves with their toes facing downward. Next, the frame is lowered and both scooping plates are placed in the grooves, and when each toe reaches the bottom of the groove, the driving devices for both scooping plates are activated to rotate the left and right scooping plates inward.

When the left and right scooping plates rotate inward, their toes move almost horizontally and cut into the soil from near the bottom of the left and right grooves, cut the bottom part of the root of the tree, and scoop out the root. state. At this time, the telescoping link is further expanded and contracted to swing the scooping plate up and down to prevent unnecessary root cutting, and when the digging device is raised, it is placed on the left and right scooping plates that are closed in an almost horizontal position. The tree is dug up with the dug-up root section on top.

After fixing the tree dug up in this way on a scooping board and moving it to the hole that has been dug in advance at the desired location,
Lower the digging device and put the root into the hole together with the scooping plate, open the scooping plate near the bottom of the hole, and move this scooping plate to both outsides of the root. When expanded and contracted, the scooping plate can be easily pulled out from the lower part of the root. Then raise the left and right scooping plates.

<Example> Hereinafter, an example of the present invention will be described based on the accompanying drawings.

In FIGS. 1 and 2, the traveling device 1l, the fuselage 5, the lifting mechanism 7, the digging device 6, etc. are almost the same as those of the conventional example shown in FIG. 3, so they will be explained in more detail based on FIG. "explain.

The above-mentioned elevating mechanism 7 is attached to the frame of the aircraft body 5 so as to be able to rise and fall freely using a pin 18 as a fulcrum, and the hydraulic cylinder 1
3, a tilt arm l4 whose lower end is swingably attached to the middle part of each lift arm 12, and a tilt cylinder 17 which drives both tilt arms 14. ing.

A pair of left and right forward supporting rods 9 are fixed in parallel to the lower part of the frame 8 of the digging device 6. The lower end rear part of the left and right brackets l6 vertically rising from the rear ends of both support rods 9 to the rear part of the frame 8 rotatably connects the tip of the lift arm 12, and the upper end rear part of the bracket 16 and the tilt arm l4 The upper end is rotatably connected to both ends of the tilt rod 15, and when the cylinder 13 is expanded and contracted, the lift arm 12 rises and falls with the bin 18 as a fulcrum, and when the tilt arm l4 is rotated by the cylinder 17, the support rod 9 is bracket l6 and lift arm l
It rotates up and down using the connection point of 2 as a fulcrum.

Therefore, by appropriately operating the cylinder 13 and cylinder 17, the left and right support rods 9 can be raised and lowered in a horizontal state.

In this embodiment, a telescopic link 25 is used in place of the link 21 in the conventional example shown in FIG. 3 for connecting the outer ends of both scooping plates 10 to both support rods 9.

This telescoping link 25 is a hydraulic cylinder, and the rear end of the cylinder is rotatably connected to the rear end of the scooping plate 10 by a bottle.
The tip of the piston rod protruding from the tip of the cylinder is rotatably connected to the upper and lower outer protrusions of each support rod 9 by means of a pin. The hydraulic cylinder 23 is connected between the protrusions on the outer upper sides of both scooping plates 10 and the upper ends of brackets 26 erected on the intermediate portions of the support rods 9.

Next, a procedure for digging up the tree T using the above-mentioned device will be explained.

First, as shown in FIG. 1, trenches 3 are dug on both sides of the root of the tree T, and roots on both sides of the root of the tree T are cut. This groove 3
The formation of the trench can be done manually, but it is more efficient to use a small trench excavator.

It is also better if the roots of the tree T are cut before and after the root by digging grooves before and after the root. The digging equipment is the first
With the left and right scooping plates 10 open as shown in the figure, that is, with the toes 24 of the scooping plates 10 facing downward, the scooping plates 10 are positioned above the left and right grooves 3 by the traveling device 1l of FIG. let

Next, the digging device 6 is lowered by the lifting mechanism 7 and inserted until the toe 24 at the lower end of the scooping plate 10 reaches near the bottom of the groove 3, and then the left and right hydraulic cylinders 23 are activated to raise the scooping plate IO. close. In this way, when the scooping board 10 is closed, its toe 24 moves almost horizontally as described above and cuts into the soil from near the bottom of the groove 3, cutting the lower surface of the tree's root. It will be in a state where you can scoop out the root part.

In this state, the left and right telescopic links 25 are expanded and contracted to swing both scooping plates 10, the toes 24 are moved up and down to prevent root breakage, and then the digging device 6 is raised to close it in an almost horizontal state. The tree is dug up with the shelved root part placed on the left and right scooping boards.

Since the scooping board 10 is gently curved inward and hugs the root, the tree remains stable even if the tree is placed on the scooping board 10 without being fixed and the digging device 6 is raised. It is safer to secure the tree with robes, etc.

The digging device 6 holding the tree in this manner is moved over the planting hole, and after the device 6 is lowered to allow the scooping plates 10 to reach the bottom of the hole, the cylinder 23 is operated to move the left and right scooping plates 10. Open and backfill the arbor.

<Effects of the Invention> As described above, the present invention provides upper and lower links that are rotatably attached to at least the front and rear upper and outer portions of the left and right support rods that are attached to the frame of the lifting device in a forward-looking manner. The outer ends are rotatably connected to the upper ends of the left and right scooping plates and the inside slightly lower than the upper ends, and both scooping plates are gently curved inward to close the two scooping plates. This scooping board has been modified so that its toes trace a nearly horizontal trajectory to cut into the root of the tree, and the upper link is a telescoping link. When cutting into the lower part, the bottom of the root can be easily cut, which was almost impossible with conventional manual methods, and the bottom of the root can be cut off almost horizontally from the surrounding ground using a scooping plate. This prevents the roots extending downward from being torn off, and the tree does not move up and down when opening and closing the scooping boards. By making the link a retractable link, when the left and right scooping boards are cut into the base of the tree, when the telescoping links are expanded and contracted, both scooping boards swing up and down to prevent unnecessary root cutting. effective.
