Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention supports and transports piled concrete lumps, soil lumps, excavated lumps, etc. at a construction site, transfers them to a waiting truck, and transplants trees. A self-propelled engine with a tree transplantation work device and a tree using the device, which is used for general purpose by attaching a device (hereinafter referred to as a tree transplant work device) to a self-propelled drive machine such as a bulldozer or a power shovel. Regarding transplantation construction method.

[Prior Art] Conventional excavators, backhoes, tractor excavators, and the like are examples of conventional construction machines that contain and transport these piled concrete blocks, soil blocks, and excavated soil blocks.

Further, as for a tree transplanting device which has been conventionally used by being attached to a self-propelled engine such as a bulldozer, see, for example, Jitsuko Sho 53.
-23644 publication tree transplanting machine, JP-B-57-55371 publication tree transplantation construction method and its device, Jitsukai Sho 60-36
Tree transplanting device described in Japanese Patent No. 060 and JP-A-60-137215
There is a tree transplanting device described in the publication.

[Problems to be Solved by the Invention] In any of the above-mentioned conventional construction machines, in order to self-accommodate soil lumps, concrete lumps, and the like in a bucket, there is a variation in the storage amount due to simply scooping from one direction or scraping. The large amount of soil and concrete that are stored in the bucket are not restrained and held, so the soil and concrete that easily enter the bucket easily fall out. During transportation, it spills due to large shaking and vibration and is scattered around. In addition, it is very difficult to house large irregularly shaped concrete blocks, rocks, and stumps in a bucket by itself, and work efficiency is poor.

However, in the case of the conventional tree transplanting device, both left and right pair of buckets or left and right pair of fork-shaped excavating and carrying claws are laterally opened and closed to perform work, so that the work is carried out in the soil around the tree root. In the lateral open swing at the stage of inserting the left and right buckets or the pair of left and right fork claws from the left and right sides, the structure is such that it largely eats out of the width of the self-propelled motor, so thinning out when trees are densely packed. It was not transplantable, and the structure attached to the self-propelled motor was large and heavy, and the maneuverability of small turns was poor, and there was a difficulty in transplanting work on slopes. To dig up the root of a tree and transport the transplanted place, carry it on a truck waiting, or when carrying the root with a bucket or fork claw without a truck or without a truck, Since the weight is added, the self-propelled engine becomes a retracted posture and one of the front and rear is in a floating state or a seesaw state, and the operation is extremely unstable and dangerous, especially in places with severe unevenness and slopes, Not only does it drag the ground to hurt the root during transportation,
After dragging, the ground is largely carved and traces remain, necessitating post-leveling treatment, and it is impossible to support a tree whose center of gravity is biased to the upper part during transportation and the balance is lost and the tree is laid in front of the open side of the parallel U-shaped mounting frame. There is enough fear that both trees and trees will overturn self-propelled motors, and no safety measures have been taken against personal injury accidents.

In addition, as a preparatory step for tree transplantation work, before excavating the root, use a conventional tree transplanting machine after digging a root cutting groove around the root of the tree with a power shovel etc. and cutting off the root branches protruding in the surrounding soil. It was something to dig up. Therefore,
Construction machines such as power shovels that excavate the root cutting ditches must be kept on standby at the site separately from the tree transplanting machine, which requires labor and construction equipment rent. 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 weakening the vitality, resulting in poor rooting and withering after transplantation.

As a result, excavation of the root cutting ditch was indispensable, and it was a laborious and costly work because it became a two-person tripod cooperative operation such as a tree transplanting machine and a power shovel.

In this regard, the present invention is a compact, lightweight, compact and versatile maneuverability, has general versatility as a construction civil engineering machine (construction machine) similar to the conventional one, and has a room for a self-propelled engine to enter at least a dense tree area. For example, a tree transplanting work device that can easily perform work even on sloping ground, does not cause the self-propelled prime mover to slip into the ground even when transporting trees, and can also perform root cutting trench excavation work as a preparation process It is intended to provide a self-propelled engine and a tree transplant construction method.

[Means for Solving the Problems] The above-mentioned problems can be solved by adopting the novel characteristic constituting means and methods enumerated below by the present invention.

That is, a self-propelled prime mover with a work device such as tree transplantation according to the present invention is a self-propelled prime mover such as a bulldozer or a power shovel, a lifting / lowering mechanism provided in the self-propelled prime mover, and the lifting / lowering mechanism. -A mounting back frame pivotally attached to the undulating mechanism, and a pair of left and right toggle sand arm link mechanisms whose front end portions are pivotally attached to the left and right upper ends of the mounting back frame so as to be horizontally pivotable horizontally and extend forward. , Pivotally attached to the tip of the toggle side arm link mechanism,
A double-edged blade that rotates in the front-rear direction and excavates a root-cutting groove around the root of a tree, and a pair of left and right front buckets, and is detachably provided on one side outside each tip of the front buckets and extends straight. Of the root cutting blade and the front bucket are formed to have a size substantially equal to the size of the front bucket, and are pivotally mounted between the lower ends on both the left and right sides of the mounting back frame, and rotate in the front-rear direction to mutually cooperate with the front bucket. It is characterized in that it is provided with a rear bucket, which is sandwiched from both front and rear sides to dig the root of the tree.

The tree transplanting construction method according to the present invention is a self-propelled engine, and is attached to the self-propelled engine so as to be able to move up and down and up and down, and to move in the up, down, left, and right directions, and to rotate in the front-rear direction for excavation, A pair of left and right front buckets are attached to the self-propelled engine so as to face the front buckets, and the front buckets are formed to have a size substantially equal to the size of the front buckets that are integrally closed. In a tree transplant construction method using a self-propelled engine with a work device such as tree transplant with a rear bucket to be excavated, advance the self-propelled engine to the immediate rear of the target tree, and move the left and right front buckets. The step of operating to excavate the root cutting groove on the rear side of the tree, expanding the left and right front buckets in the left and right horizontal direction, and until the target tree passes between the left and right front buckets and is inserted at a predetermined position While advancing the driving prime mover A step of operating the right and left front buckets to excavate the root cutting grooves on the left and right sides of the tree, and closing the left and right front buckets in the horizontal direction, and operating the right and left front buckets to cut the front side of the target tree. A step of excavating a groove, a step of piercing the left and right front buckets in an integrally closed state into the front root cutting groove of the target tree and at the same time piercing the rear bucket into the rear root cutting groove of the tree,
Until the tip ends of the left and right front buckets and the rear bucket come closest to each other, the left and right front buckets and the rear bucket are rotated to dig out the root of the target tree, and the step of carrying and lifting the tree, and the target. With the tree carried and lifted, the process of advancing the self-propelled engine to the planting hole, and dropping the target tree that was carried by opening the left and right front and rear buckets above the planting hole and And the step of implanting.

[Operation] Since the present invention takes the above-mentioned means and construction method, the operation of the pair of left and right toggle side arm link mechanisms cantilevered forward from the left and right upper ends of the mounting back frame in the transplanting operation. The front and rear and left and right side root cutting trench excavation is performed by swinging back and forth with the front left and right buckets.
In the case of excavating left and right bilateral root cutting grooves, the left and right front buckets are separated from each other when the left and right toggle side arm link mechanisms are horizontally swiveled outward, and the tree to be transplanted from the gap parallel to the excavation is the toggle side arm link mechanism. Between them, especially between the toggle parts. When digging the roots of trees, the left and right front buckets are closed when the left and right toggle side arm link mechanisms are horizontally swiveled inward, and the left and right front buckets are swung back and inserted into the front root cutting groove while the rear buckets are moved forward. It is oscillated and rotated, and is inserted into the rear root cutting groove, the front ends of the front and rear buckets come close to each other, and lower root cutting of the root portion is performed while lifting and carrying.

Therefore, digging up the roots of trees should be done with the front left and right buckets.
The two rear buckets are oscillated from the front and back to be sandwiched while cutting the lower side, and finally the front bucket tip claw and the rear bucket tip claw are closed in a butt shape.

When carrying and carrying piles of lumps of soil, concrete blocks, rocks, etc., first rotate the rear bucket forward and wait in a horizontal state, then move the left and right front buckets to the left and right toggle side arm link mechanism. Repeatedly rocking back and forth in accordance with the above, to scrape and store the clods, concrete blocks and rocks in the rear bucket as much as possible, and the clods, concrete blocks and rocks stored from the front and back with the left and right front buckets closed. Since it is lifted and transported while being stably sandwiched and restrained, it is less likely to fall out of the front and rear buckets even if it is subjected to vibration or slight shaking, so it can carry and carry a full capacity at a time, resulting in high work efficiency and efficiency.

Needless to say, it is possible to work by operating the front and rear buckets at the same time. This is especially effective when carrying and carrying while excavating.
