Abstract

PURPOSE:To facilitate transplantation of tree, etc., in a narrow place by fitting a working device for transplantation to a bulldozer, inserting and setting the tree between a left and a right toggle side arm link mechanism, and moving while bearing the root between buckets situated fore and aft. CONSTITUTION:Through an elevate/sink and rise/fall mechanism B a working device C for transplantation of tree is fitted to a bulldozer A. In advance the area surrounding the root of the tree to be transplanted is excavated, and the tree is inserted and set between a left and a right toggle side arm link mechanism 21. Then the root is borne by a front bucket 23 and a rear bucket 25, and the link mechanisms 21 are elevated and raised upright, and digging-up is performed. Then the bulldozer A is run to a specified place, and the root is set in a provided dint followed by filling-back. This allows simple installation to the main motive machine and provides a mobility with small radius of turning curvature to facilitate digging-up of the tree and its transportation to a narrow place or to a slope.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to carrying and transporting piles of concrete blocks, soil blocks, excavated soil blocks, etc. at construction sites, transferring them to waiting trucks, and transplanting trees. The present invention relates to a self-propelled main motor with a tree transplantation work device which is used for general purpose by attaching the device used for tree transplantation, etc. to a self-propelled main motor such as Bourdeaux'f.

[Prior Art] Power shovels, backhoes, tractor shovels, and the like are examples of conventional construction machines that accommodate and transport piled-up concrete lumps, earth lumps, excavated earth lumps, and the like.

Furthermore, conventional tree transplanting devices that are attached to self-propelled main engines such as bulldozers are also
-Tree transplanting machine described in Publication No. 23644, Special Publication No. 1983-
Tree transplantation method and device described in Publication No. 55371,
There are a tree transplanting device described in Japanese Utility Model Publication No. 60-36060 and a tree transplanting device described in Japanese Patent Application Laid-open No. 60-137215@.

[Problems to be Solved by the Invention] In all of the above-mentioned conventional connecting lines, the amount of soil and concrete that can be stored in the bucket varies by simply scooping it up or raking it up from one direction. Therefore, the soil or concrete lumps that easily enter the bucket are likely to spill out, and the capacity is small despite the bucket capacity, which is inefficient. While being transported, large shakes and vibrations may cause the product to fall, causing damage to surrounding areas. In addition, it is very difficult to accommodate large irregularly shaped concrete blocks, rocks, and stumps in the bucket, resulting in poor work efficiency.

However, in the case of the above-mentioned conventional tree transplanting devices, the work is carried out by moving the left and right pair of buckets or the left and right pair of fork-like excavating/carrying claws in the horizontal direction. In the lateral opening and opening swinging stage in which the left and right buckets or the pair of left and right fork claws are pushed in from both sides, the configuration extends far beyond the width of the self-propelled main motor, so if trees are densely populated, thinning and transplanting is required. This was impossible, and the structure attached to the self-propelled main engine was large and the mold was bulky, resulting in poor maneuverability and making it difficult to transplant on slopes. To dig up the root part of a tree and transport it to the transplant site, you can either load it onto a waiting truck, or carry the root part with a bucket or fork claw in a place where a truck cannot enter or without using a truck. As crystals are added, the self-propelled main engine becomes stuck in a position with one of the front and rear parts floating or in a seesaw state, making operation extremely unstable and dangerous, especially on extremely uneven or sloping areas. Not only does it drag on the ground during transportation, damaging the roots, but it also causes damage to the roots (dragging).
After the tree was removed, a large amount of dirt was left behind, necessitating post-leveling treatment, and during transport, the tree's center of gravity shifted toward the top, and the tree lost its balance and fell forward on the open side of the planar U-shaped mounting frame. There is a good chance that the self-propelled main engine could be overturned by trees or trees, and currently no safety measures have been taken to prevent accidents resulting in injury or death.

Here, the present invention is small and light, has excellent maneuverability in small turns, and can be easily operated even in areas with dense trees or slopes where there is at least enough width for a self-propelled main engine to enter, and when transporting trees, the roots are not affected. It is an object of the present invention to provide a self-propelled main motor equipped with a device for work such as tree transplantation, which does not cause the self-propelled main motor to sink into the ground and drag on the ground.

[Problems to be Solved by the Invention] The above-mentioned problems can be solved by the self-propelled main engine equipped with a tree transplanting work device of the present invention, which is equipped with a self-propelled main motor such as a bulldozer through a fluid pressure-operated lifting/lowering mechanism. In a work device such as tree transplantation to which the mounting back frame is pivotally attached, the tip of the fluid pressure-operated toggle side arm link mechanism extends forward from the upper end of both left and right sides of the mounting pack frame by opening the entire length upper side outward and slanting forward. A pair of left and right front buckets operated by fluid pressure are hung and pivoted rearward so as to be able to rotate and swing freely, while a pair of front buckets operated by fluid pressure in the width direction of the front lower end of the mounting back frame are pivoted so as to be able to swing back and forth. This is achieved by employing the above-mentioned configuration means which is hung and pivoted facing the left and right front buckets facing forward.

[Function] Since the present invention employs the above-mentioned configuration means, during the transplanting work, the pair of left and right trouble side arm link mechanisms extending forward from the upper ends of both the left and right sides of the mounting back frame are connected to the upper end of the entire length. Since the front side arm link and the left and right front buckets of the problematic side arm link mechanism are swung forward and rotated, the left and right front buckets will be separated from each other, and the tree to be transplanted will fall out of the gap. Set between trouble side arm link mechanisms, especially between trouble parts. Also, when digging the roots of a tree, when the front bucket and the front side arm link are oscillated backwards and inserted into the soil, the front buckets approach each other to perform root cutting and close the gap between adjacent tips.

Therefore, digging up the roots of a tree requires multiple front buckets and one
The two rear buckets are oscillated and rotated from the front and back to clip the roots while cutting, and finally the front bucket tip claw and the rear bucket tip claw butt against each other to form horizontal sides and close.

In addition, when carrying and transporting piled up clods of earth, concrete blocks, rocks, etc., first rotate the rear bucket forward and wait in a horizontal position, then rotate the front bucket forward and backward together with the front side arm link. By repeatedly rocking, the rear bucket is filled with soil, concrete, rocks, etc., and the front bucket is also chained horizontally to stably sandwich and restrain the soil, concrete, rocks, etc. stored from the front and back. Since it is lifted up and transported, there is little risk of it falling out of the front and rear buckets even if it is subjected to vibrations or slight shaking, so it is possible to carry and transport a large amount of cups at once, resulting in high work efficiency and efficiency.

It goes without saying that the front and rear buckets can be operated simultaneously in the same way as in the above-mentioned transplanting work. This is particularly effective when carrying and transporting while excavating.

Next, the operation of the tree transplanting work device C of this embodiment during the transplanting work will be explained.

First, a pair of left and right front side arm link operation cylinders 36
The left and right front bucket operation cylinders 45 and the left and right rear bucket operation cylinders 30 are operated to operate the left and right front side arm links 22 and the left and right front buckets 23 as shown in phantom lines in FIG.
Open the bucket 25 forward and the rear bucket 25 backward.
J is rotated up and down to find a large gap between the left and right front buckets 23 adjacent to each other, and from there a tree is inserted between the left and right relay trouble parts 40 of the left and right trouble side arm link mechanisms 21.

Next, the left and right front side arm link operation cylinders 36, the left and right front bucket operation cylinders 45, and the left and right rear bucket operation cylinders 30 are operated to move the left and right front side arms 1\links 22 and left and right front buckets 23 rearward as shown by solid lines in FIG. The rear buckets 25 are swung and rotated forward, respectively, and inserted into a circumferential groove (not shown) that has been previously dug in the ground around the roots by machine or hand, and while cutting the roots, the left and right front buckets 23 The rJj chain oscillates and rotates until the pawl 48 and the pawl 49 of the rear bucket 25 approach horizontal abutment.

At this time, the adjacent spaces g between the left and right front buckets 23 are narrowed, and they are also in a closed state as shown in FIGS. 3 and 4. At the final stage, the lower side of the root is forcibly supported from the front and back by the left and right front buckets 23 and the rear bucket 25.

Subsequently, the raising/lowering operation cylinder 12 and the raising/lowering operation cylinder 16 of the raising/lowering/lowering mechanism B are operated to integrally remove the left and right trouble side arm links 811I with the mounting back frame 7.
The roots of the tree are dug up by raising the tree 121, and the roots supported by the left and right front buckets 23 and the rear bucket 25 are lifted to a predetermined height.

Thereafter, the bulldozer 8 is driven to the transplant site and brought to the top of the excavation hole at the transplant site, and the left and right lifting operation cylinders 12, the left and right raising and lowering operation cylinders 16, the left and right front side arm ring operation cylinders 36, the left and right front bucket operation cylinders 45, The left and right rear bucket operating cylinders 30 are operated to puncture the roots and gently place the root part into the cavity to complete the back-transplanting operation.

In the present invention, the work equipment C for tree transplantation etc. is constructed to be smaller, lighter and more compact than the bulldozer A, so the bulldozer 8 is driven to the transplanting site with the tree root supported by the front and rear buckets 23.25. In other cases, the heavy water was too far forward, causing bulldozer A to lean forward and drag its roots across the ground with its rear part lifted up, and the balance of the tree became unstable due to the unevenness and slope of the ground it was traveling on. The danger of overturning a tree or overturning the bulldozer along with the tree while traveling is completely eliminated, and the bulldozer can be transported at a high speed that is incomparable to conventional travel speeds.
Efficiency can be achieved.

The work of storing and transporting earth and concrete blocks is also carried out in the same way.

[Effects of the Invention] Thus, the present invention provides a compact and robust structure for the tree transplantation work equipment, which provides stability to the bulldozer, increases transportation speed, and allows the bulldozer to fit into narrow spaces where the bulldozer can barely fit during transplantation work. It makes it possible to dig up and transplant trees planted on slopes or slopes, eliminate tree fall accidents and achieve safe work, eliminates dragging marks on the surface during transport, and eliminates clods of soil and concrete. Even in the storage and transportation work, the amount of storage in the front and rear buckets at one time is several times that of the conventional continuous line, and it has excellent effects such as being able to fully demonstrate m-mobility without sacrificing storage speed and reliability.
