Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a transplanting device used for transplanting trees in the construction or remodeling of golf courses, parks, industrial complexes, resort development, etc., particularly bulldozers, etc. This invention relates to a self-propelled main motor with a tree transplanting device attached to the self-propelled main motor and a tree transplanting method using the same.

[Prior Art] Conventionally, regarding a tree transplanting device that is attached to a self-propelled main engine such as a bulldozer, for example, Japanese Utility Model Publication No. 53-236
Tree transplanting machine described in Publication No. 44, Special Publication No. 57-5537
Tree transplantation method and its device described in Publication No. 1, Utility Model No. 6
There are a tree transplanting device described in Japanese Patent Publication No. 0-36060 and a tree transplanting device described in Japanese Patent Application Laid-Open No. 137215/1984.

In addition, Utility Model Publication No. 1-26210 is equipped with a planting water sprinkling pipe after being transplanted and backfilled, and when a tree that has been dug and transported is to be transplanted into a planting hole, the water pressure is 5 K9 /
There are some types of AI that can spray water down to the lower part of the roots of the tree, which improves the rooting of the tree.

[Problems to be Solved by the Invention] However, in both cases, work is performed by swinging a pair of left and right buckets or a pair of left and right fork-shaped excavating/carrying claws laterally to open and close, so the left and right buckets are buried in the soil around the root of a tree. Or, if the left and right pair of fork claws are inserted from both the left and right sides by the same amount of lateral rocking, the structure extends far beyond the width of the self-propelled main motor, so thinning and transplanting is not possible in cases where trees are densely populated. In addition, the structure was large and heavy, and the maneuverability in small turns was poor, making it difficult to transplant on slopes. In addition, when digging up the roots of a tree and transporting it to the transplant site, it is necessary to transport it on a waiting truck, or to carry it upright in a place where a truck cannot enter or without using a truck, by holding the root with a bucket or fork claw. Due to the added weight of the trees, the self-propelled main engine becomes stuck in the position, with either the front or the rear floating or seesawing, making operation extremely unstable and dangerous.
This is especially true in areas with severe unevenness or slopes, and not only will the roots be damaged by being dragged along the ground during transportation, but the ground will also be significantly gouged down after dragging, resulting in the need for post-leveling treatment. There is a good chance that the center of gravity will not be able to support the tree, which will lose its balance and cause the tree to fall over, or the self-propelled main engine will overturn along with the tree.According to the Industrial Safety Standards Act, dangerous work becomes extremely noisy, and safety is prioritized over work. In the current situation where the 1 principle is strongly desired, the current situation is that no safety measures have been taken to prevent accidents resulting in injury or death. Moreover, if such an unnatural posture continues, the sprockets and rollers of the caterpillar on the side of the tree from the center of the self-propelled main motor are subject to severe wear, causing cracks between the attachment and the mounting part of the self-propelled main motor. This increases repair costs and shortens the lifespan.

Also, in the above-mentioned publication, a clamp piece is shown to support the tree when digging up the roots of the tree, but such a weak support cannot support a large tree, and even more so when it is planted on a slope or in a tilted position. If you dig something up, the center of gravity at the top of the tree will be significantly skewed, so you may lose your balance and end up in an unexpected situation where you fall over the tree.

Furthermore, when transporting and transplanting dug up trees to a nearby location within 15 meters, the self-propelled main engine is moved forward each time.
Driving operations such as backing up, making U-turns, and turning back are required, which can be very difficult in places where the terrain is narrow or densely covered with trees.

In any case, conventional tree transplanting devices have a complicated structure, are large trees, and are heavy and expensive.

In addition, as a preparatory step for tree transplantation work, before digging up the roots, use a backhoe or the like to dig a root cutting groove all the way around the roots of the tree, cut off the roots that overhang the surrounding soil, and then use the conventional tree transplanting machine. It was something to dig deep into. Therefore, apart from the tree transplanting machine, a backhoe or other civil engineering machine that excavates the root cutting trench must be kept on standby at the site, which increases the cost of manpower and civil machine rental fees. Therefore, it is possible to omit digging the root cutting groove and dig up the roots all at once using a tree transplanting machine, but in this case, the roots around the roots are compressed and cut off, and the cut surface is split into thin pieces and then transplanted. After transplanting, the eye part develops root rot and its vigor becomes weak, resulting in poor rooting and withering after transplanting.

As a result, excavating root cutting trenches was indispensable, requiring two people working together with a tree transplanting machine and a backhoe, making it a laborious and expensive task.

Furthermore, the lower side of the root is supported closed by opposing buckets or forks on both the left and right sides, and is transported as it is).
When bringing the tree up to the top of the planting hole and opening the left and right buckets or forks to drop the roots in, the tip claws of the left and right buckets or forks get caught on the roots and the top of the machine, and the roots and the top of the machine come apart, causing the roots to fall apart. As it falls into the planting hole, air may get into the roots, and the roots that have been attached to the roots will have to be scraped off. We have all experienced that if the roots do not take root well, the ability to take root will be greatly reduced, and in the worst case scenario, the tree will die.

In this respect, the present invention is small, light and compact, has excellent maneuverability in small turns, and can be easily worked in areas with dense trees or slopes where there is at least enough width for a self-propelled main engine to enter, and it does not damage the roots when transporting trees. To provide a tree transplanting device that does not cause the self-propelled main motor to sink into the ground and drag the tree on the ground, prevents the tree from falling during transplanting work, and allows for quick and simple work without deteriorating the rooting power of the roots. The purpose of this project is to provide a self-propelled main engine and a method for transplanting trees.

[Means for Solving the Problems] The above problems are achieved by the present invention employing the following characteristic configuration means and techniques.

The first feature of the present invention is that a mounting frame is pivotally connected to a self-propelled main engine such as a bulldozer via a fluid pressure-operated lifting/lowering mechanism, and a fluid pressure-operated bucket is provided over the entire lower length of the mounting frame. is hung and pivoted so that it can freely swing back and forth, while a fluid-pressure-operated upper holding plate that has a cutout in the tree insertion recess and covers the upper side of the bucket is hinged to the mounting frame so that it can swing up and down, and on the other hand, the This is a self-propelled main engine equipped with a tree transplanting device, which is equipped with a fluid-pressure-operated extrusion plate that can move forward and backward on the inside surface of the bucket back plate.

A second feature of the present invention is a self-propelled main motor with a tree transplanting device, wherein the bucket according to the first feature has a group of elliptical arc-shaped claw blades protruding densely over the entire length of the tip of the bottom plate in a detachable and replaceable manner. It is.

A third feature of the present invention is that the bucket according to the first or second feature has a jet water supply pipe that communicates with a jet nozzle provided at an arbitrary or right and left outermost claw blade top end protruding from the bottom plate portion. This is a self-propelled main engine with a tree transplanting device, which is embedded in the bottom plate part and the back plate part.

A fourth feature of the present invention is the above-mentioned first feature. The self-propelled main engine according to the second or third feature is a self-propelled main engine equipped with a tree transplanting device, which is equipped with a rotating jib crane.

A fifth feature of the present invention is a construction method in which a tree transplanting device attached to a self-propelled main motor so as to be able to rise and fall and raise and lower is operated on the self-propelled main motor to transplant a tree. A bucket is provided on the lower side of the mounting frame so as to be swingable back and forth, and has a jet nozzle as required at the top end of the claw blade protruding from the tip of the bottom plate, and a bucket is provided to cover the upper side of the bucket so as to be swingable up and down to open and close. A top holding plate with a tree insertion recess and a push-out plate provided on the inner surface of the back plate of the bucket so that it can move forward and backward are operated in sequence to drill and place planting holes as necessary, and first, the target tree is placed. The self-propelled main motor is advanced to just behind the rear side, and the bucket is operated to excavate the rear root cutting groove, or high-pressure jet water is jetted from the jet nozzle to trace the rear root cutting line, and then the By operating the bucket, the self-propelled main motor is gradually advanced by applying the tip of the bucket to the rear root cutting groove or the rear root cutting line, and cutting the root part of the tree root with the group of fore-fertilizing claw blades while cutting the root part to the lower side of the root. At the stage where the bucket is lowered, the upper holding plate is closed and swung downward to insert the main body into the recessed part of the tree and press down the root topsoil from above, and then the self-propelled main motor is moved forward to While continuing to cut the roots with the group of claw blades, dig up the roots of the holly tree and lift them from the ground surface, and then, while holding the upper part of the roots with the upper holding plate, firmly support the roots, and then implant the bucket. The self-propelled main motor is advanced until it is directly above the hole, and the upper holding plate is opened and swung upward, and at the same time the self-propelled main motor is gradually retreated while the extrusion plate is advanced to move the root portion out of the bucket. This is a tree transplant method that involves extruding the tree and gently dropping it in.

[Function] Since the present invention takes the above-mentioned means and techniques, after excavating or scraping the posterior root cutting groove or the posterior root cutting line immediately after the tree, an elliptical arc-shaped nail is inserted into the posterior root cutting groove or the posterior root cutting line. By simply moving the self-propelled main motor forward using the group of blades, the roots of the tree can be cut and dug up at once with the group of claw blades. When digging up the roots and transporting them, the upper holding plate is closed to prevent the tree from falling over and the root soil from spilling out of the bucket, and the tree is tied and suspended using a rotating jib crane. Further safety is ensured, and if the transplant location is within the maximum rotation radius of the rotating jib crane, the tree can be hoisted onto the rotating jib crane and transported by rotation, making it unnecessary to drive the self-propelled main motor and using the rotating jib crane. With this installation, the self-propelled main engine can maintain a good front-to-back balance while transporting trees to ensure safe driving, and the planting hole can be closed at the roots by the slow retreat of the self-propelled main engine and the extrusion action of the extrusion plate. Since it can be planted in one piece without loosening the soil or root soil, its rooting ability does not decline even after backfilling.

Therefore, the tree transplantation method of the present invention is shown in Figs. 5(a) to (f).
), we will explain the construction procedure when applied to self-propelled main engine A with a tree transplant device.

As a preparatory process for the tree transplantation work, if necessary, the self-propelled main motor A is advanced to the tree α transplantation location, the left and right holding plate operating cylinders 24 are hydraulically operated, and the upper holding plate 21 is opened and placed. The left and right arm operating piston/cylinder mechanism 2, the left/right tilt operating piston/cylinder mechanism 5, and the bar/cerato operating cylinder 15 are hydraulically actuated as appropriate to create the elevating/lowering mechanism B.
The bucket 13 is operated via the left and right lift arms 1, the left and right tilt shafts 7, and the mounting frame 3 to open the implant hole β.
Separately excavate and place <<See Figure 5 (a)>>.

After placing it there, first, advance the self-propelled main motor A to just behind the target tree α, and move the left and right arm operating piston/cylinder mechanism 2 and the left/right tilt operating piston/cylinder mechanism 5.
Then, the bucket operating cylinder 15 is hydraulically operated as appropriate to operate the bucket 13 via the left and right parallel lift arms 1, the left and right parallel tilt shafts 7, and the mounting frame 3, and the claw blade 4 is
In two groups, excavate the rear root cutting groove γ1 while cutting the root branch α1 that overhangs into the soil (see Figure 5 (bl)), or use the bucket 1
The group of claw blades 42 of No. 3 are directed diagonally toward the ground, jet water ε is injected from the left and right jet nozzles 45, and depending on the water pressure, the root branch α1 is also cut while the posterior root cutting line γ2 is drawn (Fig. 5). See b2).

Next, in advance, the wire hoisting roll 36 of the rotary jib crane D shown in FIG. Alternatively, hook the wire 39 to the tree α, hydraulically operate the boom cylinder 34 of the rotating jib crane D, raise the telescopic slide boom 35 slightly, and attach the hoist hook or the wire 3.
9 tensioned, and hydraulically actuate the left and right arm operation piston/cylinder mechanism 2, left and right tilt operation piston/cylinder mechanism 5, and bucket operation cylinder 15 as appropriate to remove the left and right parallel lift arms 1, left and right parallel tilt shafts 7, and mounting frame 3. While operating the bucket 13 through the handle and simultaneously moving the self-propelled main drive 111A forward 9 degrees, insert the tip of the bucket 13 diagonally into the rear root cutting groove 11 (Fig. 5 (C1)).
Refer to Figure 5 (C2) or insert it into the posterior root cutting line γ2.

Subsequently, when the self-propelled main motor A is advanced and the bucket 13 is inserted under the root α2 while cutting the root branch α1 with the group of claw blades 42, the presser plate operation cylinder 24 is hydraulically operated as appropriate to raise it. Close and swing the holding plate 21 down to insert the tree into the recessed part 21
Insert and set the core part α3 of tree α to a, and set the root part α
2. Forcefully press down the topsoil G1 (see Figure 5 (d)).

Furthermore, the left and right arm operation piston/cylinder mechanism 2, the left and right tilt operation piston/cylinder mechanism 5, and the bucket operation cylinder 15 are hydraulically operated as appropriate, and the upper presser plate is connected to the left and right parallel lift arms 1, the left and right parallel tilt shafts 7, and the mounting frame 3. 21 and the bucket 13 to hold the root α2 from above and below, operate the bucket 13, continue to move the self-propelled main motor A forward, cut the root α1 with the group of claw blades 42, and completely cut the root α2. The root α2 is lifted to a predetermined height (Fig. 5(e)).
reference>.

When digging and lifting the root part α2, the hydraulic cylinder 40 is hydraulically operated to step on the leg 41 on the ground G and raise the telescopic slide boom 35 to reduce the burden of lifting the tree α on the bucket 1-13. Also good.

When transplanting to a nearby location, hydraulically actuate the left and right holding plate operating cylinders 24 to swing the upper holding plate 21 upward, and then hydraulically actuate the extrusion plate operating cylinder 29 to move the root portion α2 into the bucket 1.
3 In parallel with pushing out the left and right boom operation cylinder 3
4 to raise the telescopic slide boom 35, pull out the root part α2 of the tree α from inside the bucket 13 and lift it higher, rotate the rotary shaft plate 33 at a desired angle, and at the same time drive the wire hoisting roll 36 to raise the wire 37. Adjust the length of the telescopic slide boom 35 by hoisting up or letting out the telescopic slide boom 35, and bring it above the excavated implantation hole β at the transplanting location, and operate the boom operation cylinder 34 to lower the telescopic slide boom 35 and place the root α2 into the implantation hole β. Gently place and backfill, then remove the hoist hook or wire 39 to complete the transplantation work.

When transplanting to a place where the telescopic slide boom 35 cannot reach, the hydraulic cylinder 40 is operated hydraulically to pull up the leg 41, the bucket 13 supports the root α2, and the upper holding plate 21 supports the upper side of the root α2. Since the tree α is firmly pressed and held to prevent it from falling over, and it is hoisted by the rotating jib crane D and has a good vertical balance, the weight is concentrated on the bucket 13 that supports the root α2 as in the past, and the self-propelled main engine A may lean forward and drag the root part α2 on the ground with its rear part lifted up, or the balance of the tree α may become unstable due to unevenness or slope of the running ground, causing the tree α to fall during the journey. The danger of overturning the self-propelled main motor A together with the tree α is completely eliminated, transportation can be carried out at a high speed that is incomparable to conventional travel speeds, and work efficiency and efficiency can be achieved.

Further, when the root α2 is brought above the implant hole β, the left and right arm operation piston/cylinder mechanism 2, the left and right tilt operation piston/cylinder mechanism 5, the bucket operation cylinder 15, and the boom operation cylinder 34 are hydraulically actuated as appropriate in order to make the implant hole β. Lower the root α2 together with the tree transplant device C inside the tree,
After opening the upper presser plate 21, the extrusion plate operating cylinder 2
9 is hydraulically actuated to move the extrusion plate 31 forward, the root α2 is pushed out of the bucket 13 while the self-propelled main motor A is also gradually retreated (see Fig. 5(f)), and is finally completely removed. Then, the root α2 is transferred from the bucket 13 to the implantation hole β, and when it is stable upright, the hoist hook or wire 39 at the tip of the telescopic slide boom 35 is removed and the root α2 is backfilled.

In short, the method of the present invention is a construction method in which a tree transplanting station C attached to a self-propelled main motor A so as to be able to rise and fall freely, is operated on the self-propelled main motor A to transplant a tree.
A jet nozzle 45 is provided at the top of a group of claw blades 42 protruding from the tip of 3b.
The bucket 13 with which the target tree α has been opened, the upper holding plate 21 having the tree insertion recess 21a, and the extrusion plate 31 are operated in sequence to drill and place the planting hole β as necessary. The self-propelled main motor A is advanced to the rear end, and the bucket 13 is operated to excavate the rear root cutting groove γ1, or the high pressure jet water ε is injected from the jet nozzle 45 to dig the rear root cutting line γ.
2, then operate the bucket 13 to remove the bucket 13.
The self-propelled drive 11A is gradually advanced with the tip in the rear root cutting groove γ1 or the rear root cutting line γ2, cutting the root α1 of the tree α root α2 with the group of claw blades 42, and the bucket 1 is placed below the root α2.
3, the upper holding plate 21 is moved downward and the main body α3 is inserted into the tree recess 21a while pressing down the root α2 topsoil 01 from above, and the self-propelled main engine A is subsequently moved forward. While continuing to cut the root α1 with the group of claw blades 42, the root α2 is finally dug up and lifted from the ground surface, and the upper holding plate 21 is used to press the upper side of the root α2.) The bucket firmly supports the root α2. 13 to just above the implant hole β
mA is advanced, and at the same time as the upper holding plate 21 is opened upward, the self-propelled main motor is gradually retreated and the extrusion plate 31 is advanced to push the root α2 out of the bucket 13 and gently drop it into the plant. It gets crowded.

Although the bucket 13 is used in the embodiment of the present invention, if the soil is clayey, a shell type shovel without left and right side plates may be used.

[Effects of the Invention] Thus, the present invention provides a tree transplanting device with a small, light and simple structure, is equipped with a rotating jib crane, provides stability to the self-propelled main engine, increases operating speed, and improves the self-propelled type. It is possible to dig up and transplant trees planted in narrow spaces or slopes where the main engine can barely fit, and the upper holding plate and rotating jib crane eliminate the traditional tree-falling accidents that occur during all operations, making work safer. This technology allows for transplantation in the vicinity without leaving any drag marks on the running surface, while stopping the self-propelled main motor, and even in locations where self-propelled main motors cannot be accessed. Although the work was difficult, it can be easily done using a rotating jib crane, and the machine of the present invention can perform the stripping work on the rear root cutting groove and the rear root cutting line alone, and the root cutting grooves on both left and right sides and the front side can be omitted. Significantly reduces the need for civil engineering machinery such as backhoes and manpower, and when digging up the roots, the arcuate claw blades can be used to easily cut the roots, eliminating the need for tearing or pushing them out, making them more resilient after transplanting. hold,
In addition, during the planting work, the extrusion plate smoothly extrudes the root part from the bucket, and unlike the conventional method, the root part does not become loose and crumbly, and air is trapped, thereby preventing the root part from becoming loose due to root rot.

In addition, conventionally it took four workers one day to transplant a tree with a diameter of 60 cm, but with the present invention, one driver can transplant a tree with a diameter of 60 cm.
Since it is completed in about 0 minutes, the working capacity per day is 20 trees with a diameter of 45 cm, assuming a transfer distance of 200 m.
Not only is it possible to transplant 200m, but it also has excellent effects, such as being able to dig up a large amount of soil along with the roots of the tree, eliminating the need for root rotation, and the rooting rate after transplanting being as high as 95%, with no loose roots. .

The upper holding plate, which is movable and has a tree insertion recess, and the extrusion plate, which is movable forward and backward, on the inner surface of the back plate of the bucket are operated in sequence to drill holes for planting as necessary. First, the self-propelled main motor is advanced to just behind the target tree, and either the bucket is operated to excavate the rear root cutting groove, or the jet nozzle is injected with high-pressure jet water to cut the rear root cutting line. and then operate the bucket to thrust the bucket tip into the rear root cutting groove or the rear root cutting line, and gradually move the self-propelled main motor forward to cut the root branch at the root of the tree with the group of claw blades. At the stage when the bucket is sunk below the roots, the upper holding plate is closed and swung downwards to insert the main body into the recessed part of the tree and press down the root topsoil from above, and then the self-propelled main The mower is moved forward to continue cutting the roots and branches with the group of claw blades, and after finally digging up the roots and lifting them from the ground, the upper holding plate firmly supports the roots while holding down the upper side of the roots. By advancing the self-propelled main motor to a point directly above the implantation hole, and further advancing the push-out plate while simultaneously opening and swinging the upper holding plate upward and gradually retracting the self-propelled main motor. A tree transplanting method characterized in that the roots are pushed out of the bucket and gently dropped and planted.
