Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to digging and lifting and transporting trees as a working machine for construction machines.

[0002]

2. Description of the Related Art As a conventional technique, there is a tree transplanting device having a U-shaped root cutting blade attached to a construction machine. (See Japanese Patent Application No. 49-155020)

[0003]

However, in the above-mentioned conventional one, since the swing fulcrum of the cutter is located at the rear of the tree,
It is not possible to evenly cut the surroundings according to the center of the tree, or when cutting the tree and placing the tree on the cutter and lifting it,
There were problems such as the trees interfering with the rocking fulcrum, causing the trees to tilt, causing branching, and there being no support for the surroundings of the trees during transportation.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and is a cutter support frame including a bifurcated portion having left and right cutter rotation support shafts and a mounting portion fixed to a front end of a working machine arm. , And the left and right vertical cutting blades of the tree and the root transverse blade are integrally formed with each other, and a drive mechanism including a plate, a link, a cylinder, and a pin for swinging the cutter is provided. In addition, the cutter can be swung by the drive motor if necessary, and the cutter support frame can be tilted by the drive mechanism.

[0005]

The present invention is constructed as described above, and since the cutter is rotatably supported by the bifurcated portion, the tree to be transplanted is supported by the bifurcated portion so as not to fall and the cutter is rotated at the center of the tree. Since the center can be placed, it is possible to evenly cut the periphery. In addition, a cutter supports the lower part of the tree that has been root-cut, and it can be lifted vertically in an upright position for easy transportation.

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show the first embodiment of the present invention, FIGS. 3 and 4 show the same second embodiment, FIGS. 5 and 6 show the same third embodiment, and FIG. It is an example of the construction machine which works by attaching the tree transplanting apparatus by an example.

1 and 2, the cutter support frame 1
0 is a forked portion 10a and a working machine arm 21 such as a construction machine.
It consists of a mounting part 10b fixed to the front end, and a forked part 10a.
Has a left and right cutter rotation support shaft 11. The cutter 1 has a vertical left and right cutting blade 12 of a tree and a root transverse blade 13 which are integrally formed, is rotatably attached to the cutter rotation support shaft 11, and is connected to a link 23 by a pin 25. The link 23 forms a drive mechanism 2 for swinging the cutter 1 by about 180 degrees through a pin 25 by connecting with a cylinder 24 provided on the front end 21 of the work machine arm and a lever 22. That is, the movement of the cylinder 24 causes the cutter rotation support shaft 1 to move.
The cutter 1 will be rotated with 1 as the fulcrum,
The cutter support frame 10 is a fixed system that does not move and tilts with respect to the work machine arm front end 21.

Next, a second embodiment shown in FIGS. 3 and 4 is an embodiment in which the arrangement of the lever 22 is changed, and the operation and effect are exactly the same as those in FIGS.

Further, in the third embodiment shown in FIGS. 5 and 6, the drive mechanism 2 of the cutter 1 is performed by the drive motor 26 provided on the cutter rotation support shaft 11, and the function of the cylinder 24 is the cutter support frame 10. This is a tilt method that allows tilting with respect to the front end of the work machine arm 21.

Next, a tree transplanting operation using the apparatus of the present invention will be described in the order of FIGS. 8 to 10. FIG.
In (a), the tree transplanting device is positioned at the center of the tree to be transplanted. FIG. 8B shows a state in which the cutter rotation support shaft 11 is in the center of a tree and the cutter 1 is in contact with the ground surface.
To drill. FIG. 9A shows a state in which the cutter 1 is rotated by about 180 degrees and root cutting around the tree is performed. Figure 9
(B) shows a state in which after the root cutting work, the cylinder 24 is returned and the cutter 1 is stopped almost directly under the tree. FIG. 10 shows FIG.
A state in which the tree (2) is dug by the boom (not shown) of the construction machine and the arm 21 is placed on the cutter 1 and lifted.

In addition to the above-mentioned three embodiments, the following modifications are also conceivable, and the outline will be briefly described below. FIG.
1 is a side view showing a fan-shaped cutter for easy lifting and carrying, and FIG. 11 (B) is a root cutting blade 1 for easy lifting and carrying.
