Description

[Detailed explanation of the idea] The present invention relates to a tree transplanting device.

Traditionally, tree transplanting equipment used when constructing golf courses, housing lots, landscaping, etc. consists of a self-propelled vehicle that performs everything from digging up the tree to planting it, and an excavator equipped with a retractable bucket type excavator. A pair of buckets are opened and dug into the ground, and both buckets are closed and moved underground.
Next, a device in which both buckets are raised is known.

However, in the former case, it is difficult to match the root cutting width at the base of the tree with the excavation width of the ground.
In consideration of leaving as much of the roots as possible,
This results in an excessive amount of digging into the ground, and as a result, since this is a type of tree that already has high digging resistance, the digging resistance will further increase, and cleaning up the remaining hole after digging the tree will become a hassle. ing.

In addition, in the latter case, it is difficult to close the bucket underground, so complete closure cannot be achieved, and as a result,
This will make it impossible to extract the tree, and in order to avoid this, if the bucket is dug from the vicinity of the trunk, more roots will be removed than necessary.

To solve these problems, there is a tree transplanting device proposed by the applicant and disclosed in Japanese Patent Publication No. 57-55371.

The excavator and transport machine used in this device has a frame that is open at the front and has a roughly U-shaped planar shape, so that the tree can be received. It has digging and holding claws that are pivoted opposite each other so that it can be driven and rotated by a drive mechanism up to the closed position in an approximately horizontal state.
The device is constructed by connecting this to a self-propelled main machine such as a bulldozer using a link mechanism and a lifting drive mechanism so that the lifting operation and the opening/closing operation of the above-mentioned claws can be controlled on the main machine. It is something.

With the device configured as described above, there is no need to dig into the ground more than necessary or exceed the cutting limit, and since the claws are hawk-shaped, it is easier to cut into the ground than with a bucket. It is highly effective as it has low resistance, has an appropriate digging width, reduces the load during work, does not damage the roots, can be easily dug out of the ground, and makes it easy to dispose of remaining holes. be.

The present invention is a further improvement of the above-mentioned device, and its purpose is to make it possible to supply water to the claws in a timely manner, turning the soil into muddy soil, which is then used when digging trees. The work load can be reduced, and the tree can be easily dug out of the ground without damaging the roots, and the tree can be carried and transported in a stable state. In particular, it is useful when trying to transplant the dug and transported tree into a planting hole. By supplying water from the above-mentioned claws, it is possible to spray water even to the lower surface of the root of the tree, which is most difficult to reach by simply supplying water from above, making it possible to supply planting water effectively and quickly without any effort. The aim is to improve the efficiency of the work and to improve the survival of the trees.

The present invention will be described in detail below based on the illustrated embodiments. As shown in FIGS. 1 to 5, an excavating and transporting machine 2 is connected as an attachment to a self-propelled main machine 1 such as a bulldozer. The excavator/transport machine 2 has an opening 4 at the front end to accommodate a tree 3.

It is configured so that it can be pierced into the ground G in the horizontal state, and can support a tree 3 that has been dug up as described below when it is closed horizontally.

The excavating and holding claws 7, 7' are driven by a drive mechanism 1, such as a hydraulic jack, which is pivotally mounted to the right and left frame rods 6, 6' of the frame 5, respectively.
It is pivotally connected to the tips of the output shafts 11 and 11' at 0 and 10' via an operating rod 21 as described later, and is configured to be rotated by opening and closing drive by the drive mechanisms 10 and 10'. .

The excavating and transporting machine 2 is based on a frame 5 so that it can be operated up and down in a horizontal state in the cockpit 1b of the main engine 1 by means of a link mechanism 13 and an elevating drive mechanism 14 such as a hydraulic jack. Lead the end 1
It is pivotally connected to the frame 1a.

Further, in the illustrated example, both of the excavating and supporting claws 7, 7' have their proximal ends connected to bucket parts 7a, 7'.
7'a, the tip portions are formed into fork parts 7b, 7'b, which can be closed to the substantially horizontal position shown by the solid line in FIG. The bucket parts 7a and 7'a can be opened in the substantially vertical position shown by the two-dot broken line in the figure, and the fork parts 7b and 7'b are closed in the horizontal position, and the bucket parts 7a and 7'a are shown in the solid line in the figure. As shown, when the inner concave curved surfaces face left and right and the hawk parts 7b, 7'b are opened in a substantially vertical position, the bucket parts 7a, 7'a
As shown by the two-dot broken line in the figure, the concave curved surface is formed substantially downward, and is pivotally mounted 8, 8' to the lower portions of the left and right frame rods 6, 6' of the frame 5. .

Here, the bucket portions 7a of the claws 7, 7',
7'a is a gutter-like part 15 curved into a substantially semicircular shape;
The front and rear horizontal plate parts 16 that close the longitudinal opening of the gutter-like part 15 form a substantially semi-cylindrical cross section, so that the root part 3b of the tree 3 can be held from both left and right sides. be.

Further, the fork portions 7b, 7'b have a structure in which a plurality of claw pieces 17 are arranged side by side from the tips of the gutter-like portions 15 of the bucket portions 7a, 7'a at appropriate intervals in the front and rear direction. ing.

Each claw piece 17 of these hawks 7b, 7'b...
As shown by solid lines in FIG. 4, both claws 7 and 7' are made long enough so that their tips abut against each other when closed in a substantially horizontal position, or made so that their tips overlap by a desired length. At the same time, as shown in Fig. 3, they are installed side by side with an inclination forward in plan view, and the ground G
It has become more convenient for cutting the roots 3a of trees 3 and trees 3.

Further, the above-mentioned claws 7, 7' are as shown in FIG.
A boss 18 provided on the outside of the proximal end of each of the bucket parts 7a, 7'a and a bracket 19 protruding from the lower surface of the left and right frame rods 6, 6' of the frame 5 are pivotally connected by a shaft pin, One end is pivotally connected to another flatket 20 protruding from the lower surface of the frame rods 6, 6', and the intermediate part is pivotally connected to a boss 18' provided inside the proximal end of the bucket part 7a, 7'a, respectively, by a shaft pin. The other end of the operating rod 21 is pivotally connected to the output shafts 11, 11' of the pivot mechanisms 10, 10' by a shaft pin, and the extension and contraction of the output shafts 11, 11' causes the claws 7,
7' can be closed horizontally or opened vertically as described above.

Furthermore, two support rods 2 are protruded forward in parallel from the base end of the frame 5 to support the tree 3.
2, 22' are provided.

Furthermore, in the present invention, the above-mentioned digging and holding claw 7,
7' is configured to include a plurality of water discharge pipes 23 that open on the side of the claw piece 17, and each of the water discharge pipes 23... is connected to the frame 1 of the main engine 1.
It is connected by piping 25 to a water tank 24 mounted on the frame 5 of the excavating and transporting machine 2, etc.
Tree 3 is excavated and transported as described below,
When transplanting into a planting hole G' that has been previously drilled in the ground G, planting water can be supplied to the lower part of the root portion 3b.

Here, each of the water discharge pipes 23 .
a, 7'a along the outer wall surface, and are fixed in parallel at appropriate intervals in the front-rear direction, with their tips opening near the base ends of the claw pieces 17... Planting water can be sprayed in the length direction of the claw pieces 17..., and the base end of each water discharge pipe 23... is fixed to the base end of the bucket parts 7a, 7'a for a long time in the front-rear direction. The connected pipes 26 are connected to the water tank 24 by flexible tubes 27, respectively, and the connected pipes 26 are connected to the water tank 24 by piping 25.

Moreover, since both the claws 7 and 7' open and close as described above, a flexible tube (see FIG. (not shown) is used.

In addition, when the water tank 24 is mounted on the aircraft as described above, it is possible to control the spraying of planted water or stop the water spraying from the cockpit 1b of the main aircraft 1. Since it is located in the planting area and can be installed above ground, in such a case,
In addition to operating the above-mentioned device, a worker on the ground will perform an operation to spray or stop the water spraying.

Further, the above-mentioned planted water may be discharged by natural flow from the above-mentioned water discharge pipe 23, and furthermore, a pump (not shown) may be installed in the middle of the above-mentioned pipe 25 etc. to apply appropriate water. It may also be released under pressure.

Therefore, in the above configuration, using this, tree 3
When transplanting a tree, the main engine 1 is operated to move close to the tree 3 to be transplanted.

At this time, the excavating and transporting machine 2 is raised so that it does not interfere with traveling.

When approaching the target tree 3, first open both claws 7, 7' vertically, and in this state, the main engine 1 moves the excavator/transporter 2 through the opening 4 of the U-shaped frame 5. From there, the tree 3 is moved forward so that it can be received between the support rods 22, 22' within the machine, but this is preferably done while the drive mechanism 14 is lowering the machine.

In this way, in front of the tree 3, both claws 7,
The hawk parts 7b and 7'b of 7' will pierce the ground G at a position close to the tree 3 as shown in Fig. 6 A to B, so by continuing to move forward, the tree 3 on the ground G
The left and right sides are cut to an appropriate depth as shown in Figure C.

When the tree 3 is received up to the approximate center of the U-shaped frame 5 in this way, the ground G on both left and right sides and the long outwardly extending portion of the roots 3a are
It is cut by the claw pieces 17 of the claws 7, 7'.

In other words, both left and right sides of the tree 3 have been uprooted.

Next, both claws 7, 7' are connected to each drive mechanism 10, 1.
When they are driven and rotated inward by 0' and closed,
Since both the claws 7 and 7' rotate inward about the pivot points 8 and 8' with respect to the frame 5, at this time,
Each claw piece 17 is located on the lower side of the root portion 3b of the tree 3 and holds the root portion 3b as shown in FIG.

At this time, the root 3a of the tree 3 is cut between the bucket parts 7a, 7'a of both claws 7, 7', extending in the front-back direction, by each claw piece 17... The roots 3a extending downward from between the nail pieces 17 are not cut. The uncut roots 3a extending in the direction and downwards will be pulled out or cut, so if the aircraft 2 is raised further, the roots 3b of the tree 3 will be as shown by the solid line in Figure 4. Thus, it is dug into a substantially spherical shape and at the same time is supported in an upright state on both claws 7, 7'.

Also, at this time, the lower part of the root part 3b has both claws 7, 7'.
It is supported on the fork portions 7b, 7'b, and its right and left sides enter into the recesses of the bucket portions 7a, 7'a and are held there.

When digging the tree 3 as described above, if the ground is dry or hard, it is preferable to supply water from the water tank 24, so that the water is supplied to the claw pieces 17, and the soil is excavated. The area to be excavated will be turned into mud, making it easier to carry out excavation work.

Once the tree 3 has been dug up and carried in this way, the main machine 1 can be used to move the excavator/carrying machine 2 and the tree 3 to the desired transplanting location, and the excavated tree 3 can be carried to the desired location. Can be transported in an upright position.

Therefore, if a planting hole G' is drilled in advance at the transplanting location as shown in FIG. As the claws 7, 7' are gradually opened, the hawk portions 7b,
It can be slid down from above 7'b and dropped into the planting hole G'.

In addition, since the planting direction of the tree 3 can be freely controlled by running the main machine 1, after dropping the tree 3 into the planting hole G' in the desired direction as described above, the posture of the tree 3 is corrected. However, in this case, after advancing the excavating and transporting machine 2 to the top of the planting hole G' as described above, the opening of both claws 7, 7' is Prior to this, a valve (not shown) of the piping 25 is opened and the pump is driven to discharge water from the water tank 24 from the water discharge pipes 23 installed in the claws 7, 7'. Then, planting water is supplied to the root part 3b of the tree 3 and the planting hole G'.

When supplying the above-mentioned planting water, a method for quickly supplying a sufficient amount of water to the root portion 3b is as follows:
By operating the main machine 1, the excavating and transporting machine 2
Raise it slightly and insert the claw piece 17 into the implant hole.
It is preferable to float it from the bottom surface of G', so that water flows along the claw piece 17 and the root part 3b
The water supply will reach the bottom of the center.

After supplying a sufficient amount of potting water to the root portion 3b in this manner, or while supplying potting water, open both claws 7, 7' and as described above, open the hawk portion 7b,
It slides down from above 7'b and falls into the planting hole G', and then the root part 3b is filled with soil to complete the transplantation.

In addition, the water discharge pipe 23... is the bucket part 7a, 7'a.
If it is attached to the nail piece 17, it will penetrate into the soil after excavation, so there will be no risk of actual damage as it will not be subjected to large external forces, and there will be no clogging due to dirt etc. This does not occur, but only flows out when water is supplied, and if a small amount of water is constantly supplied at this time, clogging can be completely prevented.

As explained above, according to the tree transplanting device according to the present invention, the digging/carrying claws 7, 7', which can be freely rotated inwardly by a closing drive until they become substantially horizontal, are provided at the lower portions of the left and right sides of the U-shaped frame 5. In a transplanting device in which an excavating and transporting machine 2 formed by pivotally mounting is connected to a self-propelled main machine 1 such as a bulldozer by a link mechanism 13 and a lifting drive mechanism 14, the claw 7 of the excavating and transporting machine 2 is , 7' are provided with a plurality of water discharge pipes 23 that open on the side of the claws 17, and these water discharge pipes 23 are connected to the main machine or the excavating and transporting machine, or to an appropriate place on the ground. Since it is connected to the installed water tank 24 so that it can be opened and closed, by supplying water to the claw pieces 17 when digging, it is possible to prevent the ground G from being too dry and solidified, or when the ground G is sticky. Even if there is no soil, excavation using the claws 7 and 7' becomes easier, and by supplying an appropriate amount of water into the soil, not only can the root part 3b retain more soil, but also the tree 3 can be easily excavated. Drilling, both claws 7,
7' to carry the root part 3b to the transplant site, open both claws 7 and 7', and drop it into the pre-drilled transplant hole G' for transplantation. Prior to dropping into ', the water discharge pipe 23...
By discharging water from ..., the root part 3b and the planting hole
Of course, it is possible to supply planting water to G', and when planting, connect both claws 7 and 7' to the planting hole.
By raising G' slightly from the bottom surface, it is possible to quickly supply planting water in sufficient quantity to the entire lower part of the base 3b, which was difficult to do by simply supplying water from above with a hose. It is possible to prevent the trees from dying and improve their survival, as well as
You can expect efficient work.
