BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tree transplanting device.

[0002]

2. Description of the Related Art The work of transplanting a tree includes a work of digging a tree, a work of moving the digged tree to a predetermined place, and a work of planting the moved tree. In the work of digging up a tree, first, a groove is dug around the root of the tree and root cutting is performed. And there is work to pull up the tree. In addition, when planting a tree, there is a work of lowering the tree at a predetermined position of the dug-down planting hole. These works cannot be handled manually because the tree becomes heavy when the tree becomes large, and attempts have been made to use a power machine.

For example, a technique (Japanese Patent Application Laid-Open No. 57-12934) relating to a tree transplanting apparatus as shown in FIG. 5 is disclosed. Reference numeral 50 denotes a frame, which is attached to the left and right of a self-propelled main machine such as a bulldozer. An excavation claw 52 is rotatably attached to the lower end protrusion 51 of each frame 50. Reference numeral 53 denotes a cylinder device, which is rotatably supported on an upper portion of a support column 54 extending on the frame 50. Reference numeral 55 denotes a first link, one end of which is axially attached to the tip of the rod 56 of the cylinder device 53, and the other end of which is axially attached to the midway portion of the excavation claw 52. Also, 57
Is a second link, one end of which is at the tip of the rod 56 of the cylinder device 53 and the other end of which is the lower end protrusion 51 of the frame 50.

According to the link mechanism of this device, when the rod 56 of the cylinder device 53 is contracted as shown on the left side of FIG. 5, the excavation claw 52 is in a state of hanging downward. That is, the excavation claw 52 is in the open position. Then, as the rod 56 of the cylinder device 53 extends, the excavation claw 52 rotates inward to a substantially horizontal closed position as shown in the right side of FIG. When excavating a tree with this device, first, the pair of excavation claws 52, 52 are advanced into the excavated groove around the root of the tree. Next, the pair of excavation claws 52, 52 are rotated inward. As a result, it is possible to raise Ri drilling to take scooping trees.

[0005]

However, in the conventional tree transplanting apparatus described above, the excavating blade 5 is provided by the link mechanism.
Since it operates so as to occlude 2, the digging blade 52 operates so as to cut the downwardly extending root, and at the same time, to clamp the root of the tree. For this reason,
The root of a tree receives a compressive load and is damaged by being crushed. Further, the compressive load may cause the earth and sand adhering to the root portion to fall off and damage the root. Further, in the closing operation of the excavating blade 52 described above, the driving force acts not only to cut the root of the tree and to pinch the root, but also to lift the tree. Therefore, there is a problem that the root of the tree is pulled and damaged. Also a scoop

Reference numeral 26 is a cylinder device, which is rotatably supported at the rear end on the upper portion of a support column 28 extending on the support arm 12. Rod 27 of this cylinder device 26
Is attached to a rotating shaft 31 of a rod mounting portion 30 projecting from the upper part of the outer surface of the scooping plate 18.

FIG. 4 is an explanatory view in which the above tree transplanting device is mounted on the backhoe 32. As apparent from the figure, a tree transplanting device is attached to the tip of the arm 34 instead of the bucket of the backhoe 32. In this embodiment, since the tree transplanting device is large, the arm 34 is set shorter than the normal one in the balance thereof. Therefore, the tip end of the rod of the cylinder device 36 that moves the arm 34 up and down is pivotally attached to the shaft 40 provided on the protruding portion protruding upward from the arm 34. Reference numeral 42 denotes a cylinder device, which can rotate the tree transplanting device at a predetermined angle around the shaft 41 at the tip of the arm 34.

Next, the operating state of the above embodiment will be described with reference to the drawings. First, as shown in FIG. 1, the cylinder device 2

Is in the open position, pulled up. In this state, the supporting arms 12 and 12 are positioned so as to sandwich the tree T from both sides by the self-propelled vehicle shown in FIG. 4, and the tip of the scooping plate 18 is inserted into the groove excavated around the tree T.

When the rod 27 of the cylinder device 26 is extended, the scooping plate 18 is rotated until it is closed inward as shown in FIG. That is, the scooping plate 18 draws an arcuate locus along the arcuate groove 16 of the guide 14 and moves so as to scoop the root while cutting the root extending downward.

Since the root portion of the tree is scooped in this way, the scooping plate 18 does not operate to pinch the root portion of the tree, and the root is not damaged by the compressive load. Further, when the scooping plate 18 moves along the arcuate groove portion 16, it is not necessary to apply its power in the direction of lifting the tree. Therefore, the tree can be suitably separated from the soil without pulling the root of the tree or damaging it. Further, the power of the cylinder device 26 is generated by the scooping plate 1.
It is used only for sliding 8 and does not disperse in the force for pinching or the force for lifting, so that it can operate favorably. As a result, the power plant can be downsized.

Next, the tree is pulled up by the elevating mechanism provided in the self-propelled vehicle as shown in FIG. In the embodiment shown in FIG. 4, the arm 34 is lifted upward by extending the rod of the cylinder device 36. At this time, the cylinder device 42 is adjusted so that the tree transplanting device is maintained horizontally. As a result, the trees that are scooped by the scooping board 18 and separated from the ground can be suitably lifted.

Further, even when working wear planting trees raised which Ri drilling as described above, the apparatus suitably acts. First, with the tree transplanting device, the tree is moved to a predetermined position in the planting hole while holding the tree as shown in FIG. Next, the scooping plate 18 is moved along the guide 14 so that the scooping plate 18 is in the open state as shown in FIG. 1, and the tree is positioned in the planting hole. At this time, since the scooping plate 18 only slides in an arc shape, it is possible to appropriately position the tree in the planting hole without tilting the planting mud or fertilizer thrown into the planting hole. .

In this regard, in the conventional apparatus shown in FIG. 5, since the excavating claw 52 is rotated like a door, the operation of the excavating blade 52 separates the mud and the like thrown into the planting hole. Will end up. Further, since the root portion of the tree is slid on the excavation claw 52 to be positioned in the planting hole, it is difficult to position the tree without tilting it.

In the above embodiment, the circular groove 16 is fixed to the support arm 12, and the two pins 20 and 20 are used for the scooping plate 1.
Although the case of being fixed to the 8 side has been described, a member equivalent to two pins is arranged on the supporting arm 12 side in an arcuate position to form an arcuate guide, and an arcuate groove is provided on the scooping plate 18 side. Of course, it is good. In other words, so as to guide the scoop plates 18 in a circular arc shape, and a guide portion and the guide portion may be provided relatively to the support arm 12 and scoop plate 18.

Further, in the above embodiment, it was explained that the scooping plate 18 operates in an arc shape, but the cylinder device 2
It is also possible to utilize the power of 6 and combine it with other operations. For example, in the embodiment shown in FIG. 1, the scooping plate 1 is provided with a linear groove portion which is continuously provided above the arc-shaped groove portion 16.
It is also possible to move 8 linearly. At this time, if the linear groove portion is set wider than the arcuate groove portion 16, the two pins 20, 20 arranged in the arcuate shape can also slide properly. Although various preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and many modifications can be made without departing from the spirit of the invention. That is.
