  The bucket 4 is provided on both sides of a liftable lifting frame 7 formed in front of the traveling device 6 via a link mechanism 8 so that the bucket 4 can be opened and closed left and right. The bucket 4 includes a bottom plate 9 that is curved and end plates 10 that are provided at both ends of the bottom plate 9. The left and right buckets 4 are formed substantially symmetrically so as to be combined in a pot shape when they are brought close to each other. In particular, the bucket 4 is formed with a shorter bottom height than the conventional one that lifts a small tree, and is formed with a wider size in the front-rear and left-right directions. This is for transplanting without leaving roots (not shown) necessary for the growth of the tree 2 in the transplant source. According to the inventor's previous practical experience, it is known that the roots necessary for the growth of the trees 2 are concentrated up to about 1 m underground, and the shape of the bucket 4 is changed as described above. Thus, a larger tree 2 can be handled.

  As shown in FIGS. 1 and 2, end plates 10 at both front and rear ends of the bucket 4 are respectively provided with stoppers 12 that are engaged with locking poles (locking portions) 11 of a moving sled 5 described later. . The stopper 12 is formed in a rod shape, and is provided on each end plate 10 so as to extend back and forth from the bucket 4. A hook 15 for hanging the chains 13 and 14 is provided at the tip of the stopper 12.

  The ski member 16 is made of H-section steel. The ski member 16 is bent upward at both front and rear ends in the traveling direction. The ski member 16 forms a bottom surface 18 that is a sliding surface with one flange surface of the H-shaped steel and an upper surface 19 with the other flange surface. In addition, the ski members 16 are arranged at three locations, the left and right sides of the moving sled 5 and the center. A front beam 20 is provided over the front ends of the ski members 16. The front beam 20 is made of H-section steel having the same cross-sectional area as the ski member 16. The front beam 20 is disposed with a pair of flange surfaces facing forward and backward.

  The loading platform member 17 is made of a flat rectangular steel plate, and is arranged at the center of the front and rear of the ski member 16. The loading platform member 17 is disposed so that the longitudinal direction is directed in the left-right direction of the movable sled 5 and the left and right sides are extended from the left and right ski members 16.

  The locking pole 11 is provided on the ski member 16 so as to be able to rise and fall in the left-right direction. The locking pole 11 is provided on the front and rear portions of the ski members 16 on the left and right sides via hinges (not shown). The distance between the front and rear of the locking pole 11 is wider than the length of the front and rear of the bucket 4, and the bucket 4 can be disposed between the front and rear locking poles 11. Further, the locking poles 11 are provided so as to fall inward between the left and right ski members 16, respectively, so that the work is not disturbed when the bucket 4 is placed on the bed member 17. The locking pole 11 is made of H-shaped steel having a smaller cross-sectional dimension than the ski member 16. When the locking pole 11 is tilted, the length is determined so that the rotating tip is placed on the ski member 16 at the center of the left and right of the moving sled 5. Further, the locking pole 11 is arranged so that the pair of flange surfaces 21 face up and down when tilted, and comes into contact with the ski member 16 over a wide area. The locking pole 11 has a flange 22 that is fitted to the stopper 12 of the bucket 4 on the loading platform member 17 when it is erected. The flange portion 22 is formed by forming a hook-shaped notch in the locking pole 11. The flange portion 22 is formed so as to be positioned at the upper portion on the rotating tip side when the locking pole 11 is tilted, and is fitted to the stopper 12 that protrudes forward and backward from the bucket 4 when rotated in the standing direction. It has come to be.

  The sled moving means 28 comprises a heavy machine such as a bulldozer that travels on an endless track.

  Next, a method for transplanting the tree 2 will be described.

  As shown in FIG. 6, a groove 23 for inserting the bucket 4 is formed in the soil on both sides of the tree 2 in advance, and the moving sled 5 is kept on the ground 24 facing the groove 23. At this time, the grooves 23 are appropriately separated from the tree 2 so as not to hang on the root (not shown) of the tree 2 and are formed parallel to each other. Further, preferably, it is formed to a depth (about 1 m or more) enough to allow the bucket 4 to completely enter. Still further, the moving sled 5 is preferably made to wait in advance with the traveling direction toward the transplant site.

  Thereafter, the bucket 4 is opened to the left and right, the elevating frame 7 of the traveling device 6 is lowered, the bucket 4 is inserted into each groove 23, and the bucket 4 is closed. As a result, the roots of the trees 2 are sandwiched between the buckets 4 and the surrounding soil and are accommodated in the buckets 4. After that, as shown in FIGS. 1 and 2, the ring 25 is attached to the trunk of the tree 2, and the ring 25 and the hook 15 of the bucket 4 are connected by the chain 13 to support the tree 2.

  Further, the chain 14 is attached to the hooks 15 of the left and right buckets 4, the turnbuckle 26 is attached to the chain 14, and the chain 14 is tightened by the turnbuckle 26 to restrict the opening of the left and right buckets 4. At this time, when the hooks 15 on the front side of the bucket 4 are connected to each other via the chain 14 and the turnbuckle 26, and the hooks 15 on the rear side of the bucket 4 are connected to each other via the chain 14 and the turnbuckle 26, the bucket 4 is balanced. Can be regulated.

  In this way, when the tree 2 is supported by the bucket 4 and the opening of the bucket 4 is restricted, the bucket 4 is raised to lift the root pot 3 composed of the root of the tree 2 and the surrounding soil, and the root Place the bowl 3 together with the bucket 4 on the moving sled 5. At this time, the bucket 4 is positioned between the front and rear locking poles 11 and the position of the bucket 4 is determined so that each end plate 10 of the bucket 4 faces the locking pole 11 of the moving sled 5. Place bucket 4 on

  Thereafter, each of the locking poles 11 is turned around the hinge to stand up. Since the locking pole 11 is made of H-section steel with a small cross section, it can be rotated manually. The locking pole 11 is restricted from rotating by fitting the flange portion 22 to the stopper 12 of the bucket 4 and is held in an upright posture, and the bucket 4 is locked to the moving sled 5.

  As shown in FIG. 7, a pulling wire 27 is attached to the front beam 20 of the moving sled 5, the moving sled 5 is pulled by the sled moving means 28, and the traveling device 6 is made to follow the moving sled 5, so that the tree 2 Move. Since the tree 2 is moved by the moving sled 5, it can be stably climbed even if the ground 24 is uneven, and the root of the tree 2 is not impacted.

  When the moving sled 5 reaches the transplantation site, the locking pole 11 is tilted to unlock the bucket 4, the lifting frame 7 of the traveling device 6 is operated to move the bucket 4 from the moving sled 5 to the transplantation ground, The bucket 4 is opened and the tree 2 is transplanted to the transplant site. Since the tree 2 is transplanted together with the soil without damaging the roots necessary for growth, the tree 2 can be stably and quickly rooted in the transplanted land.

  In this way, the bucket 4 that can be freely opened and closed is inserted into the soil on both sides of the tree 2 to be transplanted, and the root pot 3 of the tree 2 is lifted with the bucket 4 sandwiched between the buckets 4. Since the moving sled 5 moves the tree 2 to the transplanting site while maintaining the posture of the tree 2, even the large tree 2 can be reliably transplanted without damaging the roots.

  The movable sled 5 includes a plurality of long and parallel ski members 16 arranged in parallel and horizontally, a bed member 17 provided on the ski members 16 for placing the bucket 4, and a ski member. 16 is provided with a locking pole 11 provided before and after the longitudinal direction of 16 to restrict the movement of the bucket 4 in the longitudinal direction, so that a larger tree 2 can be moved while maintaining the posture with a simple structure. It is possible to prevent an impact on the root during movement.

  When the root pot 3 of the tree 2 is sandwiched between the buckets 4, the ring 25 is attached to the trunk of the tree 2, and the ring 25 and the stopper 12 of the bucket 4 are connected by the chain 13 to support the tree 2. The tree 2 can be prevented from moving on the bucket 4, and the tree 2 can be stably transplanted.

Therefore, it is possible to reliably prevent the bucket 4 from being opened during movement, and the tree 2 can be stably transplanted.

  The locking pole 11 is provided on the ski member 16 so as to be tiltable in the left-right direction, and the bucket 4 is provided with a stopper 12 engaged with the locking pole 11 extending in the front-rear direction. The bucket 4 can be easily locked to the sled 5 with a simple structure, and the tree 2 can be transplanted efficiently.

  The hook 15 provided on the stopper 12 and the ring 25 are connected by the chain 13 to support the tree 2. However, the ring 25 and the bucket 4 are directly connected by the chain 13 to support the tree 2. May be. In this case, a chain connection hole may be formed in the bucket 4. Similarly, when the opening of the left and right buckets 4 is restricted using the chain 14, the chain 14 may be directly attached to the bucket 4.

  Moreover, although the chain is used for supporting the tree 2 and opening regulation of the bucket 4, it is not limited to the chain. Any cord that can withstand a large tensile force such as a chain or wire may be used.

  The loading platform member 17 is made of a single steel plate, but may be made of a plurality of steel plates. In this case, a plurality of steel plates may be provided across the three ski members 16. Further, the pair of steel plates are oriented so that the longitudinal direction thereof is along the longitudinal direction of the ski member 16, and the left and right sides are arranged with the central ski member 16 as a boundary, and one steel plate is disposed on the central ski member 16 and the right ski member 16. And the other steel plate may be provided between the central ski member 16 and the left ski member 16.

  The sled moving means 28 is composed of a heavy machine such as a bulldozer, but may be composed of the traveling device 6 or another device.

  Further, the bucket is not limited to the bucket provided on the lifting frame 7 of the traveling device 6 via the link mechanism 8 so as to be freely opened and closed. As shown in FIG. 8, the bucket 30 only needs to be openable and closable in the horizontal direction, and may be of a type suspended by a crane (not shown), for example. The bucket 30 is connected to two wires 31 suspended from a crane via two arm members 32, respectively. One end of each arm member 32 is fixed to the end plate 33 of each bucket 30 by bolts or welding, and the other end is connected to the wire 31. Further, the arm members of both buckets 30 intersect with each other at the center in the longitudinal direction, and the intersecting portions are coupled to each other via a coupling pin 34 so as to be rotatable. Thereby, when the bucket 30 is lifted, it closes by its own weight. Further, the end plate 33 of each bucket 30 may be provided with a stopper 12 similar to that described above. When such a bucket 30 is used, when the bucket 30 sandwiching the root pot 3 of the tree 2 is moved with the moving sled 5, the moving sled 5 is caused to follow the crane, but the wire 31 is moved by slackening it.
