Description

  The present invention relates to a bucket used for a work vehicle such as a power shovel, and more particularly to a bucket used for transplanting a relatively small tree constructed by excavating from the entire circumference of a tree and extracting a root in a root pot shape. In particular, it is constructed so that it can be used manually not only in a landscape gardener but also in a general home.

Conventionally, with regard to tree transplantation, small trees have been dug down manually using a scoop or the like, but when it becomes a large tree, it is also used for transportation called bulltoza, hydraulic excavator, power shovel, etc. A work vehicle was used.
And the “bucket” that is mounted on these work vehicles and is operated by the arm seems to be called “the scooping plate” or “the scooping claw” because of its function.

That is, the surface part that covers the soil and the base is made of a plate or a claw having an arc shape, that is, a scooping plate or a claw is made to face each other to form a bucket.
And it seems that the trees to be handled are large trees with a trunk diameter of 10 cm or more, and the work procedure is to first dig a groove on both sides of the tree, and then open the bucket to open the soil from the grooves on both sides of the tree. At the same time, the tree is planted in a root pot shape.

This method digs up the soil only from the left and right direction with the tree in between, but with this, the roots in the front and rear direction cannot be completely cut, and there is a drawback that the roots are caught by a bucket and torn. . Therefore, it can be seen that it is dug down from the entire circumference of the tree.
In addition, in order to improve the efficiency of excavation, there is a method in which excavation blades are vibrated to advance the digging, but this is not preferable because the soil adhering to the fine roots may be shaken off and die.
Next, I will introduce the prior applications of some of the methods of digging from the whole circumference of trees.

  First of all, a prior application that can cut and wind a side root around the entire circumference of the tree and has an extremely simple structure is shown. Its configuration is a rectangular thin metal plate slightly curved in the short side direction, the upper short side is bent and reinforced, the lower short side is a blade, and both long sides have a plurality of connecting rings. . There are connecting shafts that are detachably fitted to the connecting ring, and a plurality of these are used. In other words, after inserting a connecting shaft through a thin metal plate and standing around a tree, the upper short side of the thin metal plate is alternately hit with a hammer or the like and driven into the soil. Equipment and a simplified operation related to the planting of trees using the device. (For example, refer to Patent Document 1).

  Next, there is an arcuate guide frame at the tip of the arm of the work vehicle, and a pair of guide grooves provided in the inner periphery of the work vehicle are fitted and held and have an opening in the front, and can be reciprocated in the horizontal direction. There is a long C-shaped sleeve at the bottom, and a ball gate consisting of a pair of hemispherical halves is pivotally attached to the inner lower edge of both C-shaped sleeves so that it can be opened and closed in the vertical direction. Is configured to close. At the center of the upper edge of the device is an open / close hydraulic cylinder for reciprocating the C-shaped sleeve in the horizontal direction. At the upper end of the ball gate, both hemisphere halves and the cutting blade are moved up and down to move the bottom. A pair of hydraulic cylinders for opening and closing is connected.

Therefore, the hydraulic pressure is set so that the C-shaped sleeve is reciprocated beyond the opening of the opening while the C-shaped sleeve is positioned in the C-shaped sleeve so as to embrace the standing tree and then pushed down into the soil by the arm force of the work vehicle. Operate the cylinders alternately and cut the side roots with the root cutting blades at the bottom of both hemisphere halves.
And when the predetermined depth is reached, the hydraulic cylinders at the upper ends of both hemisphere halves are actuated to cut the lower root and close the bottom, and the root is formed into a hemispherical shape called “tree transplanter” There is something. (For example, refer to Patent Document 2).

  Also, for large trees, the front can be opened and closed by a pair of linear motors and has a plurality of ring stands so as to surround the tree, and there are a plurality of curved pillars and a curved plate extending upward from the ring stands. Is equipped with a plurality of excavation type shovels that move up and down in parallel, and when a plurality of excavation type excavators surrounding the tree by various guide devices cut down the roots in the soil while descending by a linear motor, There is a name "tree digging machine" of the invention configured such that a plurality of lower end portions meet each other. (For example, refer to Patent Document 3).

Further, three or more scooping claws are arranged so as to surround the root portion from all directions, and these vertical movements are performed by an arm which is a lifting mechanism of the work vehicle. Each of the claw claws has a turning drive means for rotating the claw from the side of the root portion to the bottom, and the root portion can be taken out by retracting the front claw claw. There is a tree transplanting device that digs the root of the tree from all directions. (For example, refer to Patent Document 4).
Japanese Patent Laying-Open No. 2006-115823 (pages 1 and 2, FIGS. 1 to 4 and 6) JP-A-11-206250 ([0004] to [0006], FIG. 4, FIG. 7, FIG. 8, FIG. 10) JP-A-58-183020 (pages 4-7, FIGS. 3-4, 11) JP 61-31030 A (pages 5 to 8, FIG. 1, FIG. 4, FIG. 6)

The above-mentioned Patent Document 1 has the simplest configuration in the prior patent applications, and this point can be easily used by landscaping companies and ordinary households. However, it hits the upper short side of a rectangular metal sheet. Even if the roots and branch roots can be cut into the soil, the roots under the standing trees cannot be cut.
In addition, the upper short side of the thin metal plate, which is the hit part, can be bent and damaged immediately because the side is simply bent. A cut standing tree cannot be lifted from the ground.

Patent Document 2 is an excellent invention that can cut not only the side roots but also the vertical roots, and can also form the spherical roots at the same time by using a hemispherical ball gate at the inner lower edge of a pair of C-shaped sleeves.
However, in addition to using the arm force of a work vehicle for large trees, there is an open / close hydraulic cylinder for reciprocating the C-shaped sleeve in the horizontal direction at the center of the upper edge of the device. However, as a pair of hydraulic cylinders for opening and closing the bottom portion are connected by both hemisphere halves, there are disadvantages that a large-scale apparatus is employed such as employing a total of four hydraulic cylinders.

  Patent Document 3 is similar to Patent Document 2 in that the front ring stand is opened to surround the tree, the excavation excavator for excavation is lowered, and not only the side root but also the vertical root under the tree is cut. Although it is configured as above, two linear motors for opening and closing the ring stand are required, and linear motors for driving the excavator type excavator with four to eight pillars are necessary. It can be said that it is a very large device.

  Furthermore, Patent Document 4 also has a turning drive means in which a plurality of scooping claws rotate from the side to the bottom of the tree root, so that all roots are cut from the side roots to the vertical roots. However, this also requires a hydraulic cylinder and a swivel driving means having a complicated structure as many as the number of nails, which makes the apparatus large.

  As described above in detail, in the prior art, apart from Patent Document 1, it is possible to cut up to a root directly under a tree, and to crawl the root into a root pot shape so that it can be moved to a transplant destination. In addition to working vehicles such as power shovels for large trees, it was necessary to incorporate a large number of hydraulic cylinders and complicated mechanisms for cutting heavy roots and moving heavy trees.

The object of the present invention is that Patent Document 2 to Patent Document 4 have the features of Patent Document 2 to Patent Document 4 so that the root can be cut up to the root just below the tree, and the root can be lifted up into a root pot shape and moved to the transplant destination even if it is not for large trees. An object of the present invention is to provide an implanting device that has advantages and is as simple as possible and inexpensive.
Therefore, an object of the present invention is to make it suitable for transplantation of relatively small trees, and if possible, can be easily operated even in gardening in general households.

  The configuration of the present invention will be described below with reference to the drawings. In these drawings, components that are functionally the same even if they have different shapes are denoted by the same reference numerals. In addition, the lead lines are not necessarily provided at all locations to which the same reference numerals are attached, and some of them are representatively selected.

As shown in FIGS. 1 to 3, two semicircular support frames 1 arranged so as to form a ring in a horizontal direction relative to a bucket used for civil engineering work vehicle 16 such as a power shovel. It is assumed that a plurality (three in the figure) of scissors-like blades 2 are suspended in a loosely fitting manner at least inward of the ring, for example, using a short tube 23 or the like.
One end of each of the two semicircular support frame bodies 1 is pivotally mounted in parallel with the bracket 4 (two places in the figure) to be connected to the arm 7 of the work vehicle as the rotation shaft 3. The ends reach connecting end portions 6 that open and close in the horizontal direction by expansion and contraction of the expansion and contraction means 5.

  Further, on the surface of the bracket 4, there are two semicircular support frame bodies 1 that connect the centers of the arm mounting portions 8 that are arranged in parallel (four in the figure) for transmitting the arm 7 force of the work vehicle. The basis of the present invention is a plant transplanting bucket provided perpendicular to the center line of the ring to be formed.

1 and 3, the arm attachment portion 8 is shown as a through hole drilled in the square bracket 4. The work vehicle 16 as shown in FIG. Generally, the bucket mounting bracket 17 is detachably mounted and fixed.
However, depending on the structure of the work vehicle 16, the link form of the work vehicle arm 7 may be different from that shown in FIG. 8, so the work vehicle mounting arm 18 is required as shown by the chain line in FIG. In some cases, the arm mounting portion 8 is not a through hole but a bearing body as shown in FIG.

  It is assumed that the bowl-shaped blade 2 which is a main part is formed so as to bend toward the inside of the ring as it goes toward the tip of the lower end. The reason for this is that when it is press-fitted vertically into the soil, if it is a straight plate in the vertical direction, it will only enter straight into the soil, but if it is a curved plate, the direction of entry will be in the curved direction. Because it bends naturally. That is, if all the scissors-like blades 2 arranged in an annular shape are press-fitted, they will naturally advance through the soil toward the center of the ring.

In addition, as shown in FIG. 2, an obstruction plate 21 is provided at an appropriate position of the semicircular support frame 1, particularly at the lower portion of the auxiliary arm bearing 11, so that the bowl-shaped blade 2 does not tilt outward. It is desirable to provide it.
That is, since the hook-shaped blades 2 are loosely fitted in an annular shape and suspended, all of the hook-shaped blades 2 enter the inside of the ring in a centric manner, and form the bottom at the tips of the blades. It becomes like this.
Needless to say, the uppermost side of the bowl-shaped blade 2 is also curved inward on the horizontal plane so as to follow the semicircular support frame 1.

  In each illustration, three scissors-like blades 2 are arranged on each semicircular support frame 1 because it is considered that this level is appropriate. The number of sheets may be changed in relation to the length of the upper side. Also, the shape of the blade edge can vary from a straight line to an obtuse angle to an acute angle of the degree of curvature, and they can be combined without any unification, and the shape of the bowl-shaped blade 2 of the present invention Is not limited to the illustrated example.

In the case of three sheets, only the centrally arranged bowl-shaped blade 2 is arranged outside the bowl-shaped blades 2 on both sides in a ring shape, and the vicinity of the upper side is partly near the upper side of the adjacent bowl-shaped blades 2. It is good to make it overlap.
In this case, the effect described later is increased by making the centrally arranged bowl-shaped blade 2 wider in the vicinity of the upper side than the adjacent bowl-shaped blade 2. Further, as shown in FIGS. 1, 2, 5, 6, and 8, the U-shaped curved side portion for reinforcement extends from the central portion of the upper side of the bowl-shaped blade 2 to about half of the entire length downward. It is desirable to have 9.

Furthermore, as shown in FIG. 10, a short pipe motion guide frame 30 is provided near the upper surface of the inner surface portion of the bowl-shaped blade 2, which is arranged in parallel in the vertical direction and whose upper and lower sides are closed by the abutting side portion 31. If the short tube 23 that can be slidable in the vertical direction between the short tube motion guide frames 30 is fitted and the scissors blade 2 is suspended from the semicircular support frame body 1, the respective scissors shape The blade 2 can be individually pressed into the soil to a depth corresponding to the length of the short pipe motion guide frame 30.
This is particularly effective when excavation is performed only by hand without using the force of the arm 7 of the work vehicle.

  In this case, the short pipe movement guide frame 30 is not provided, and the short pipe 23 is directly fixed to the semicircular support frame 1 to transmit the force of the arm 7 of the work vehicle and move up and down together with the semicircular support frame 1. The presence of the hook blade 2 is required. As the hook-shaped blade 2 that plays the role, for example, one in which three hook-shaped blades 2 are suspended on the semicircular support frame 1 on one side, the middle hook-shaped blade 2 is applied to it, and the hook-shaped blades on both sides It is preferable that the blade 2 is provided with a short pipe motion guide frame 30.

As shown in FIGS. 1 to 4, 8, and 9, the two semicircular support frames 1 are separately applied with a pressure applied in the vicinity of the middle of the semicircular support frame 1 in the length direction. It is preferable that an auxiliary arm bearing 11 for pivotally mounting the auxiliary arm 10 for pivoting in the vertical direction is added.
Further, as shown in FIGS. 5 and 6 and FIGS. 9 and 10, a lifting hook 12 is provided near the center of the inner surface of the bowl-shaped blade 2, and FIGS. A striking head 13 for driving the scissor blade 2 into the ground using a hammering tool such as a hammer may be provided at the center of the upper side of the scissor blade 2 as seen. The shape of the head is easy to fit in either a circle or rectangle.

  In addition, as described above, it is not preferable that the cutting edge portion of the bowl-shaped blade 2 is separated from the main body so that the cutting edge portion is vibrated in the vertical direction to increase the excavation efficiency, thereby removing the soil from the fine roots. Is a large and strong vibration, and there is no great concern if it is an amplitude movement of about 1 cm, so it is omitted from the illustration, but the spring for engaging the blade edge part and the eccentric to give it a vertical movement It is also possible to have a vibration device that rotates a eccentric shaft.

Further, as an accessory of the present invention, two semicircular bodies as shown in FIG. 7 are provided so that when the saddle blade 2 is pressed into the ground, the cutting edge of the saddle blade 2 does not bend from the inside to the inside quickly. At 14, it is desirable to use together a constant diameter ring 15 configured to form a ring body.
This constant-diameter ring 15 does not easily separate the two semicircular bodies 14 even when pressed from the periphery, and when used, it can be easily divided by, for example, pulling up via a hook 28 or the like. It is necessary to make it a structure that can be removed.
As described above in detail, the present invention has been made as simple as possible to transplant relatively small trees.

  The effect of using the bucket of the present invention attached to the arm 7 of a work vehicle that is normally used is that the connecting end 6 at the front of the two semicircular support frames 1 on which a plurality of saddle blades 2 are suspended. It can be excavated from the whole circumference around the tree at once, so that it can be used for transplanting relatively small trees, but it can cut not only the side roots and branch roots but also the vertical roots directly under the trees, and the bottom Is closed and the root portion is formed in a hemispherical shape, so that the hook can be lifted to prevent the soil from falling off and to move to the transplant destination.

In addition, since the hook-shaped blades 2 are curved inward of the ring, all the hook-shaped blades 2 are directed toward the ring only by press-fitting from above. At that time, if you adjust the depth of press fit into the soil according to the tree, if you insert a constant diameter ring 15, it will interfere with the movement of each bowl-shaped blade 2 that is going to go eagerly, If the constant-diameter ring 15 is removed when the target depth is reached and further press-fitting is performed, each bowl-shaped blade 2 thereafter proceeds centrically and cuts the vertical root to form the root into a hemisphere. Become.
In addition, regarding the cutting of the root, not only the cutting edge but also the blade having the blades up to the middle of the height of the adjacent saddle-shaped blades 2 causes the adjacent saddle-shaped blades 2 to have a function similar to that of the scissors. Make it easy to cut.

The press-fitting is performed with the arm 7 force of the work vehicle via the bracket 4. However, as shown in FIG. 8, if the auxiliary arm 10 for pressing is attached, the front saddle blade 2 is more effectively press-fitted. Will be able to.
When the excavation is completed and the tree is pulled up, simultaneously with the two semicircular support frames 1 and at the same time as the arrows shown in FIG. 5 and FIG. In the diagonal direction, as shown by a thick line in FIG. 8, a rope or the like may be tied and pulled up as the lifting member 20.

In addition, in the case of one half-circular support frame 1 having three bowl-shaped blades 2, only the middle bowl-shaped blade 2 is disposed outside the neighboring bowl-shaped blades 2 so that the vicinity of the upper side is located. 1 and FIG. 2 in which the upper side of the middle bowl-shaped blade 2 is made wider than the upper sides of the neighboring bowl-shaped blades 2 has the following effects. Is produced.
That is, when the tip of the full hook-shaped blade 2 is closed, both sides of the middle hook-shaped blade 2 are overlapped so as to be held on the adjacent hook-shaped blade 2 from the outside with the widest area. If the middle hook-shaped blade 2 is pulled up, the hook-shaped blades 2 on both sides are also pulled up simultaneously.

Therefore, since it is only necessary to provide the lifting hook 12 only in the middle hook-shaped blade 2 for transplanting small trees, two lifting members 20 are sufficient.
In addition, even when the inhibition plate 21 for preventing the hook-like blade 2 from tilting outward is provided, if it is installed only in the middle hook-shaped blade 2, even if the hook-like blades 2 on both sides try to tilt outward, Since it is blocked by the middle hook-shaped blade 2, it becomes unnecessary for the hook-shaped blades 2 on both sides, and the point can be saved.

Further, if the U-shaped blade 2 has the U-shaped curved side portion 9 from the central portion of the upper side to the lower half of the entire length downward, the reinforcing effect is much higher than that of a mere curved one.
By the way, in order to cut a natural root, it is actually impossible to press-fit uniformly, so the semicircular support frame 1 often tilts. Therefore, in the case where the hitting head 13 is provided at an appropriate position of the semicircular support frame 1, the ring formed by the semicircular support frame 1 is horizontally formed by hitting it with a scissors as occasion demands. It will be possible to press fit while keeping

Furthermore, if only excavating small tree roots, the landscaping company can use only the saddle of the structure shown in FIG. It can also be used for gardening in general households.
At this time, the scissors blade 2 provided with the short tube motion guide frame 30 on the inner surface of each scissors blade 2 is suspended by the semicircular support frame 1 with the short tube 23 fitted thereto. Regardless of the height of the semicircular support frame 1 above the ground, the bowl-shaped blade 2 can be slid in the vertical direction, and the length of the short pipe motion guide frame 30 (depth into the soil) Since each of the scissors blades 2 can be arbitrarily driven by hitting the striking heads 13 of the individual scissors blades 2, an effect of facilitating excavation even by manual work is produced.

  That is, conventionally, the traveling direction of the blade has been forcibly controlled. However, since the bowl-shaped blade 2 of the present invention is loosely fitted to the semicircular support frame 1 and suspended, the traveling direction of the blade edge is A somewhat free and large-scale control device is unnecessary. In addition, the configuration eliminates large hydraulic cylinders and complicated link mechanisms as much as possible, so the cost can be greatly reduced and it can be provided at low cost.

The best mode for carrying out the present invention is to use the work vehicle 16 capable of exerting a great excavating force, and at the same time, consider that it can be used in general households that do not use the work vehicle 16 and that both can be shared. It is to make the configuration.
However, since the size of the bowl-shaped blade 2 itself should be different between a small standing tree and a large tree, the size of the semicircular support frame 1 is naturally different.
Therefore, the dimensions in size design are omitted, and only the configuration will be described.

First, as a work vehicle 16 to be used, a general use having a hydraulic cylinder 22 of a work vehicle for driving a pressing auxiliary arm 10 and the like as shown in FIG. 8 is used for mounting a flat bucket having a common shape. The bracket 4 of the present invention is also attached to the bracket 17 as a flat plate.
As a matter of course, the through hole as the arm mounting portion 8 matches the through hole in the bucket mounting bracket 17 and can be tightened and attached with a fastener such as a bolt or nut.

  By the way, all the components of this invention employ | adopt the raw material which has toughness. Therefore, the semicircular support frame 1 is a semicircular cylindrical steel pipe, and the saddle blade 2 is formed so as to bend toward the inside of the ring as it approaches the tip. It is assumed that a U-shaped curved side portion 9 such as a dent around the handle is provided.

Further, the blade at the tip is provided not only at the blade edge but also around the middle of the height on both sides. As described in the effect of the invention, the adjacent scissors-like blades 2 have a function similar to that of the scissors and can easily cut the side roots. However, it is not advisable to tie the adjacent scissors blades 2 tightly like the fulcrum of the scissors. The reason is that since it is used in the soil, it is natural that soil particles enter between the two blades, and movement between the scissors blades 2 is hindered by a large amount of soil particles sandwiched.
In this respect, since the bowl-shaped blades 2 are configured to freely swing with respect to each other, the sandwiched soil particles are easily separated.

  The method of suspending the bowl-shaped blade 2 to the semicircular support frame body 1 is such that a short tube 23 having one side for welding is inserted into the semicircular support frame body 1 at the lower side, Assume that one side is fixed to the upper two places by welding or the like. It should be noted that it is sufficient in most cases to hang three hook-shaped blades 2 on one semicircular support frame 1. Moreover, as shown in FIG. 1 and FIG. 2 described above, it is preferable that only the middle hook-shaped blade 2 is enlarged and the upper side vicinity of both adjacent hook-shaped blades 2 is hung from the outside.

Although only partially shown, it is preferable that the inhibition plate 21 is fixed to an appropriate position of the semicircular support frame 1 so as not to incline toward the outer side of the ring on all the scissors blade 2.
In this case, as shown in FIG. 8, the above-described one in which only the middle bowl-shaped blade 2 is enlarged can sufficiently fulfill its purpose if the inhibition plate 21 is attached only to the middle bowl-shaped blade 2. In other words, the adjacent saddle blades 2 are blocked by the central saddle blade 2.

  In addition, two short pipe motion guide frames 30 are provided on the inner surface of the scissors blade 2, and a short pipe 23 slidable in the vertical direction is fitted to the short pipe motion guide frame 30, so that the scissors blade 2 is attached. More preferably, each hook-shaped blade 2 can be individually press-fitted into the soil to a certain depth by being suspended from the semicircular support frame 1. In this case, the one having the three bowl-shaped blades 2 on one semicircular support frame body 1 is fixed so that the middle bowl-shaped blade 2 is fixed to the semicircular support frame body 1 and does not slide up and down. It is assumed that the short-pipe movement guide frame 30 is provided on the adjacent saddle blade 2.

  Since the connecting end portion 6 does not have to be easily detached, as shown in FIGS. 1 to 4 and 9, a short tube having an inner diameter that fits the end portion of the semicircular support frame 1 is used. It is sufficient to fix to the end portion of the counterpart semicircular support frame 1. Since soil is handled, it is easy for soil to enter the end of the semicircular support frame 1 and the short pipe, so the end of the semicircular support frame 1 is covered and the soil is easily dropped. It is preferable to drill several through holes. In addition, it is desirable to take appropriate locking means so as not to separate easily when closed.

The expansion / contraction means 5 for opening and closing the two semicircular support frame bodies 1 is a mechanism for expanding / contracting between the two expansion / contraction fulcrums 24, and each drawing is illustrated as adopting a small hydraulic cylinder body. However, since a small force is sufficient as compared with the force at the time of press-fitting into the soil, a hydraulic cylinder is not used between the two expansion / contraction fulcrums 24, but an appropriate link mechanism is sufficient although it is not shown.
In an extreme case, the expansion / contraction means 5 is not required, and the two expansion / contraction fulcrums 24 may be manually opened and closed as shown in FIG. In actual work, this is on-site considering that there is an act of confirming the locking means of the connecting end 6.

  In addition, on the principle of the insulator, an auxiliary arm bearing 11 is provided on the semicircular support frame 1 as close to the front connecting end 6 as possible without contacting the tree, and the pressing auxiliary arm 10 is provided there. Although the problem should be attached, the problem is that the work vehicle 16 is provided with an appropriate amount of movement and pressure to the pressing auxiliary arm 10 due to the link mechanism relationship between the arm 7 of the work vehicle to be employed and the hydraulic cylinder 22 of the work vehicle. It is necessary to have an optimal link mechanism. In FIG. 8, the pressing auxiliary arm 10 is pivotally attached to a horizontal shaft 25 that is orthogonally connected to the hydraulic cylinder 22 of the work vehicle.

The usage of the present invention will be described step by step with reference to FIG. The case where the work vehicle 16 is used first will be described as follows.
First, as an advance preparation, the bucket of the present invention is attached to the bucket mounting bracket 17 of the work vehicle 16 at the arm mounting portion 8 and one end of the pressing auxiliary arm 10 is engaged with the horizontal shaft 25 of the work vehicle. Similarly, one end of the lifting member 20 is temporarily fixed to the horizontal shaft 25.

A) A constant diameter ring 15 is formed around the tree 27 to be transplanted in the semicircular body 14 and placed on the ground.
B) From this, the work vehicle 16 is operated, the bucket of the present invention is brought close to the tree 27, and the connecting end portion 6 of the semicircular support frame 1 is opened by the expansion / contraction means 5.
C) The work vehicle 16 is advanced so that the tree 27 is positioned at the center of the ring formed by the two semicircular support frames 1, the connecting end portion 6 is closed by the expansion / contraction means 5, and both semicircular support frames 1 To form a ring.
D) After the cutting edge of the full saddle blade 2 is positioned outside the constant diameter ring 15, the arm 7 of the work vehicle is lowered to start excavation. The cutting edge of the full bowl-shaped blade 2 tries to advance inward as indicated by the arrow in FIG.

E) Proceed with excavation, stop excavation when the predetermined depth or constant-diameter ring 15 is close to the lifting hook 12 of the saddle blade 2, and lift the hook 28 to separate and remove the constant-diameter ring 15 To do.
F) Further excavation is carried out, and the excavation is stopped when the cutting edges of all the saddle blades 2 are gathered under the tree 27.
G) After lifting the lifting member 20 temporarily fixed to the horizontal shaft 25 of the work vehicle, the tree 27 is pulled up in a state where the root of the tree 27 is held in the shape of a root pot by the full rod-shaped blade 2. And move to the transplant destination.
Although the above is an outline, when excavating, the direction of the individual scissors blades 2 is likely to deviate, etc., it is necessary to strike the striking head 13 as necessary so that all the scissors blades 2 are dug on average. Good.

Next, a case where the work vehicle 16 is not employed will be described. The target tree 27 is a small tree, and the bucket according to the present invention is provided with the striking head 13 at an appropriate position of the semicircular support frame 1, but the auxiliary arm for pressing 10 is removed and used for lifting. It is assumed that only the hoisting member 20 as a rope body is connected to the hook 12, and the expansion / contraction means 5 is replaced with a rod-shaped handle as shown in FIG. .
In addition, it is preferable to use a rod-shaped blade 2 provided with a short tube movement guide frame 30 on the inner surface thereof.

A) A constant diameter ring 15 is formed around the tree 27 to be transplanted in the semicircular body 14 and placed on the ground.
B) The bucket according to the present invention is brought close to the tree 27, grasps both handles as the expansion and contraction means 5, and opens the connecting end 6 of the semicircular support frame 1 so as to close both handles.
C) The bucket of the present invention is advanced so that the tree 27 is positioned at the center of the ring formed by the two semicircular support frames 1, and the connecting end 6 is closed by grasping both grips as the expansion and contraction means 5. The ring of the semicircular support frame 1 is formed.
D) After the edge of the full bowl-shaped blade 2 is positioned outside the constant-diameter ring 15, the hammer heads 13 of the individual bowl-shaped blades 2 are alternately struck with a scissors or a hammer. Into the ground. At this time, the cutting edge of the full bowl-shaped blade 2 tends to advance inward as indicated by the arrow in FIG.

E) Proceed with excavation, stop excavation when the predetermined depth or constant-diameter ring 15 is close to the lifting hook 12 of the saddle blade 2, and lift the hook 28 to separate and remove the constant-diameter ring 15 To do.
F) Further excavation is carried out, and the excavation is stopped when the cutting edges of all the saddle blades 2 are gathered under the tree 27.
G) Holding the lifting member 20, the root of the tree 27 is pulled up in a state of being held by the full bowl-like blade 2 in a root pot shape, and moved to the transplant destination using a unicycle or the like.

Example 1 will be described with reference to FIG. 1. A cylindrical steel pipe is used for the semicircular support frame 1, and the bowl-shaped blade 2 is formed so as to curve inward of the ring. Part 9 was also provided. In addition, the blade has not only the blade edge but also the middle of the height on both sides.
Furthermore, the scissors-like blade 2 has three on one side, and the center-arranged scissors-like blade 2 is wider in the vicinity of the upper side than the scissors-like blades 2 on both sides.

  In addition, it is arranged on the outside of the hook-shaped blades 2 on both sides so that the vicinity of the upper side overlaps a part of the hook-shaped blades 2 on both sides, and a welding piece is provided on each upper side and on the lower side. The short tube 23 was welded. Further, the end portion of the lifting member 20 such as a wire or rope shown by a chain line as shown in FIG. . The other end of the lifting member 20 is attached to the horizontal shaft 25 of the work vehicle shown in FIG.

Further, the bracket 4 is a rectangular plate, and through holes are formed as arm mounting portions 8 at four corners in accordance with bolt holes of the bucket mounting bracket 17 of the work vehicle 16. Although the rotation shaft 3 is not shown in the drawing, it is attached to a shaft provided with a strong bearing portion using a bearing or the like above and below the end of the semicircular support frame 1.
As the expansion / contraction means 5, a small hydraulic cylinder is employed, and the expansion / contraction fulcrum 24 is expanded / contracted.

The auxiliary arm bearings 11 on which the pressing auxiliary arms 10 are axially attached are fixed to substantially the midpoints in the length direction of both semicircular support frames 1.
The connecting end 6 closes a cylindrical opening at the front end of one semicircular support frame 1 with a disk, and the front end of the other semicircular support frame 1 has an end closed with a disk. A short cylinder having an appropriate length and having a diameter for fitting was fitted.

  The second embodiment is the same as that of the first embodiment except that the arm attachment portion 8 is not a through hole but a bearing body that can be rotated in the vertical direction, as shown in FIG.

  Example 3 is the one shown in FIG. 3, in which the scissors-shaped blade 2 is three on one semicircular support frame 1, but the scissors-shaped blade 2 has no U-shaped curved portion 9. The bowl-shaped blades 2 are all of the same size and are suspended from the semicircular support frame 1 without overlapping. Therefore, the lifting hooks 12 are provided inside the hook-shaped blades 2, but the rest is the same as in the first embodiment.

  Example 4 is shown in FIG. 4 and is the same as Example 1 except that each bowl-shaped blade 2 does not have a U-shaped curved side part 9. FIG. The state in which the cutting edges of all the scissors blades 2 are gathered, that is, the time when excavation is completed and a root pot is formed is shown.

  Example 5 is shown in FIG. 5, and a cylindrical striking head 13 is welded to the center of the upper side of the selected bowl-shaped blade 2 so as not to interfere with the semicircular support frame 1. It is fixed with etc.

  As shown in FIGS. 7 and 6, the sixth embodiment is an example of the constant diameter ring 15, and by combining two semicircular bodies having a certain thickness with the stepped notch portions 26, The ring body is formed as a whole. The joint portion of the two stepped notches 26 has a pin through-hole 32 that penetrates both of them vertically, and a pin 33 inserted therethrough is dropped. Since the pin 33 is for preventing the two stepped notches 26 from coming off, it is preferable to adopt a pin that is narrower than the pin through-hole 32 so as to be easily pulled out after reaching the purpose.

For the purpose of use, it is necessary to continue to form a ring body even if it is pressed by the hook-shaped blades 2 from the periphery to the center. Conversely, when removing it, it is easy by pulling up the hook 28 provided in the center. It must be able to be removed.
When this constant diameter ring 15 is used, it starts by placing it on the ground so as to form a ring body around the tree 27 indicated by the chain line, but when the excavation work starts, the hook blades 2 come closer. Eventually, the periphery of the constant diameter ring 15 comes into contact. Since this contact pressure gradually increases, the constant-diameter ring 15 is obtained upward because its escape is below the ground. FIG. 6 shows the extreme state in this state. Even when the constant-diameter ring 15 rises, it stays on the lifting hook 12 of each hook-shaped blade 2.

This means that the constant diameter ring 15 should be removed before reaching here, and at the same time, the role of the constant diameter ring 15 that prevents each saddle-shaped blade 2 from entering the soil centripetally. Therefore, the position of the lifting hook 12 in each hook-shaped blade 2 is important.
That is, the depth at which the cutting edge is not bent into the soil and is vertically pressed is from the cutting edge of each hook-shaped blade 2 to around the lifting hook 12.

In the seventh embodiment, as shown in FIG. 9, the use of a hydraulic cylinder as the expansion / contraction means 5 is stopped, and a handle is attached as the expansion / contraction fulcrum 24 as the expansion / contraction fulcrum 24.
That is, the expansion / contraction means 5 is manually moved in both directions as indicated by arrows to open and close the connecting end 6. Although the semicircular support frame 1 has been described as an arc body because the arc is simpler, it is a polygonal body because of the attachment of a straight tube such as the short tube 23, for example. It does not matter, and they may be formed by adding them.

In the eighth embodiment, as shown in FIG. 10, two short tubes 23 directed to the inner surface of each bowl-shaped blade 2 are fitted with projecting short sides 29 projecting on both sides of the short tube 23. Then, it is assumed that a short-shaped short tube motion guide frame 30 that can slide in the vertical direction as indicated by an arrow is fixed.
That is, the short tube 23 loosely fitted in the semicircular support frame 1 is inserted and fitted from the upper and lower abutment side portions 31 of the short tube movement guide frame 30 as an opening, and thereafter The upper and lower openings are closed tightly, and the bowl-shaped blade 2 is suspended from the semicircular support frame 1.

  Since the abutting side 31 is a portion that receives pressure and impact force both in the upper and lower directions, sufficient consideration for strength is desired in design. In this way, the length until the abutting side portion 31 on the upper side of the short tube movement guide frame 30 abuts on the short tube 23, that is, the upper middle depth substantially corresponding to the length of the short tube movement guide frame 30, Since the striking head 13 of the scissors blade 2 can be individually driven, there is an advantage that the operation is easy even by manual operation. In addition, the hit | damage head 13 of this Example 8 widened the area with the rectangular shape instead of the head in order to make it easy to hit.

Further, as shown by a chain line, the attachment place of the inhibition plate 21 for preventing the saddle blade 2 from tilting outward is welded to a short cylindrical body fixed to the semicircular support frame 1. As shown in FIG. 10, the semicircular support frame 1 is provided so as to protrude upward.
Naturally, since the position where the hook-shaped blade 2 is suspended from the semicircular support frame 1 is different from that in the first embodiment, the length between the upper side portion of the hook-shaped blade 2 and the cutting edge is designed to be long. become.

In one Example of this invention, it is the perspective view shown in the state which open | released the connection edge part. Example 1 It is the perspective view shown in the state which closed the connection end part in the other Example of this invention. (Example 2) It is the perspective view shown in the state which open | released the connection edge part by what does not overlap the both sides of each hook-shaped blade in other Example of this invention. (Example 3) FIG. 2 is a perspective view showing a state in which the end portions of all the scissors-like blades are gathered in the embodiment of FIG. Example 4 It is an enlarged perspective view of a bowl-shaped blade provided with a striking head. (Example 5) It is side surface sectional drawing for description which showed only the principal part in the middle of excavation work using one Example of this invention. In the Example of the constant diameter ring of this invention, it is front sectional drawing which expanded and showed only the junction part. (Example 6) It is the side view shown in the state where one example of this invention was equipped with the bracket for bucket attachment of a work vehicle. FIG. 5 is a perspective view in which a handle is employed as the expansion / contraction means in the embodiment of FIG. 4 and the connecting end is manually opened and closed. (Example 7) FIG. 6 is a perspective view of another embodiment of the scissors-like blade according to the present invention, which is configured so that the scissors-like blade can move to some extent in the vertical direction with respect to the semicircular support frame.
