Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a digging and transporting machine for digging trees and the like for transplantation and transporting them.

[Conventional technology]

In order to transplant trees, etc., it is necessary to dig the trees and transport the trees to a predetermined place. Since there are problems in efficiency and safety in performing these operations manually, in recent years, a device having a mining device attached to the tip of a self-propelled drive device such as a backhoe or a buzzer is used.

In using such a device, the tip of the digging device is dug down to the root of the tree, and after root cutting, the tree is dug up from the root. As such a digging device, the following has been conventionally proposed. That is, as described in JP-A-60-241828 and JP-A-62-130459, a pair of left and right support rods are projected on the front surface of a frame supported by a driving device, and tree digging is provided on this. A claw for removal is attached so that it can swing in the left and right directions, and the tree is dug from the root with this claw.

A digging device as described in JP-A-62-25923, which is provided with a single digging blade that rotates approximately 90 °, and an elongate claw provided on the blade. When digging a tree with this device, the blade is dug down to a deep portion where the root of the tree is located, and then the extension claw is extended to the lower part of the root to lift the tree.

As described in Japanese Utility Model Laid-Open No. 58-26849, a semi-circular excavating blade, which is provided with vibration in the excavating rotation direction at the tip of the machine body, is provided so as to extend from the excavating blade rotating shaft and supports the front end of the excavating blade. A semicircular support arm is provided.

Etc.

[Problems to be solved by the device]

However, each of the above-mentioned conventional devices is structurally complicated, and there is a high risk that a tree may tilt during digging or may fall during transportation.

Therefore, an object of the present invention is to simplify the structure and mechanism and prevent the inclination and the fall of trees.

[Means for Solving the Problems]

The above-mentioned problem is a tree digging and transporting machine having a drive arm that is connected to a vehicle body so that it can be lifted up and down, and a bucket that is rotatably connected to the tip of the drive arm along the lifted surface of the drive arm. A side end portion of the drive arm is connected to a lateral side portion of the drive arm, and a gripping member is provided in a fixed state at the tip end portion of the drive arm so as to face the receiving side of the bucket. The member is laterally displaced from the widthwise center of the bucket, digs the tree to be mined and carried by the bucket, and stores the root pot of the tree to be mined and carried in the bucket, and then the bucket The problem can be solved by rotating the drive arm along the lie-down surface and holding the root pot by the bucket and the holding member.

[Action]

In the digging and transporting machine according to the present invention, the tip end portion of the drive arm is connected to the widthwise side portion of the bucket. For example, conventionally, when a tree is transferred using a backhoe, after excavating and root cutting with a bucket of the backhoe, the tree is suspended by a crane, placed on a truck bed, and transported by a truck. This is because the backhoe is such that the tip of the drive arm is connected to the center of the bucket and scavenges the soil toward the front side, so that the drive arm interferes and the tall tree can be stored in the bucket. Because I couldn't. Therefore, when attaching a digging bucket to the backhoe as an attachment,
It was a front bow type (digging toward the front side). However, in the case of this front-hoe type, there is a problem that it is difficult to operate because the driver cannot see the dug portion. In this respect, in the case of the present application, since the tip end portion of the drive arm is connected to the side portion in the width direction of the bucket, the drive arm and the trunk of the tree are relatively displaced, and a tree like a backhoe. It is possible to dig the root toward you and store the root pot in a bucket to move it.

Further, in the case of the mining transporter of the present application, the gripping member is provided at the tip of the drive arm so as to be laterally offset from the center of the bucket in the width direction, facing the receiving side of the bucket. Has been done. Therefore, after the tree is dug and the root pot of the tree is stored in the bucket, the root pot is gripped by the bucket and the gripping member protruding from the drive arm, and the tree is transported in an upright state. Since the gripping member is laterally displaced from the center of the bucket in the width direction, there is no hindrance to the standing of the tree.

Further, the gripping member is fixed to the drive arm, and the bucket is rotated in the direction along the elevation surface of the drive arm so that the root pot is gripped by the bucket and the gripping member. After storing the bowl, the bucket is rotated along the prone surface of the drive arm, and the root bowl is gripped by both the gripping member and the bucket continuously from the digging operation, so that a simple operation is possible. Further, since the drive arm only needs to be rotated to grip the root bowl, the operation is very easy.

Further, since the gripping member is laterally displaced from the widthwise center of the bucket, the upper part of the root pot can be suppressed by the gripping member, so that the soil of the root pot can be prevented from collapsing and the tree can be prevented. Can be stably held. Moreover, even if a tree is about to fall, it can be prevented by supporting the trunk of the tree.

Thus, when transporting the tree, the bucket and the gripping member can prevent the root pot and prevent the tree from tipping over.
You can safely transplant trees.

〔Example〕

Hereinafter, the present invention will be described more specifically by way of examples with reference to the drawings.

First, referring to FIG. 5, an outline of the whole digging device of the present invention will be described. A drive arm 2 is provided so as to be able to rise and descend on a self-propelled vehicle body 1 having wheels such as a caterpillar (registered trademark). The drive arm 2 includes the first cylinder 3A on the vehicle body 1.
The first arm 2A rotatably connected by the
At the tip of the arm 2A, there is provided a second arm 2B which is rotatably connected by the operation of the second cylinder 3B attached thereto.

Further, the bucket 4 is connected to the tip end of the second arm 2B via a connecting shaft 5 so as to rotate along the elevation surface of the drive arm 2. Therefore, the third cylinder 3C is attached to the second arm 2B, and the tip of the cylinder rod of the third cylinder 3C is attached to the connecting arm 6 rotatably attached to the second arm 2B and the back portion of the bucket 4.

The bucket 4 is connected to the second arm 2B so as to be located near the center of the width direction 4. Also bucket 4
A flexible cushioning material 11 such as rubber is fixed to the base end edge of the.

In the digging machine configured as described above, in order to dig and carry the target tree, first move the carrying machine to the front of the tree T to be transplanted, and then move the first arm 2A.
And set the second arm 2B at an appropriate angle,
While the bucket 4 is lowered by the third cylinder 3C, the first cylinder 3A is contracted, the claws of the bucket 4 are used to excavate to the root of the tree T, and then the third cylinder 3C is extended, while the root of the tree T is extended. Are stored in the bucket 4.
Following this accommodation, the connecting arm 2 is lifted up and the tree T is completely dug up on the ground surface.

By this excavation, the tree T is housed in the bucket 4 in a substantially upright state, and the transporting machine is allowed to travel to the target transplantation position as it is to perform the transplanting work.

At the time of digging, the upper part of the root bowl has a holding plate member 10a of the holding member 10.
By the above, the tree T is relatively restrained, and the tree T is stabilized, and even if the tree T tries to fall to the side of the restraining plate member 10a, the trunk hits the restraining plate member 10a, so that the tree T is prevented from falling. Further, the tree T is prevented from falling toward the vehicle body 1 by the trunk contacting the base edge of the bucket 4. At this time, since the cushioning material 11 is provided on the base end edge of the bucket 4, damage to the trunk is prevented.
