Description

  The present invention relates to a tree transplanting method in which a tree is dug from a root portion and transplanted to another place.

  Conventionally, tree transplantation work has been performed in which trees are dug from the root and transplanted to another place, as in the case of transplanting trees in the mountains to an urban park.

  This tree transplanting operation has been performed as follows (for example, see Patent Document 1).

  First, using a tree transplanter in which a substantially box-shaped bucket with the front and upper sides opened at the tip of an arm of a heavy machine, the debris on the front side of the tree to be transplanted is dug out.

  Next, a digging groove is formed in the left and right side of the tree to be transplanted and the soil behind the digging groove using a digging groove forming machine having a sharp rod-like body attached to the tip of a heavy machine arm.

  Next, using the bucket of the tree transplanter, the tree to be transplanted is dug from the ground together with the earth and sand adhering to the root.

  Next, the excavated tree is transferred from the bucket to the loading platform of the transport truck.

  Next, it conveys to another place with a conveyance truck.

  Next, the tree is transferred again from the loading platform of the transport truck to the bucket of the tree transplanter.

  Finally, the tree is placed in the bucket of the tree transplanter together with the soil at the root, and the tree is transplanted.

  Here, the conventional tree transplanter has a structure in which a substantially box-shaped bucket with its front and upper sides opened is attached to the tip of an arm of a heavy machine (see, for example, Patent Document 2).

  In the transplanting operation at the transplanting site, the heavy machinery arm is operated to incline the bucket forward, and the trees are gradually moved from the bucket to the transplanting site using the weight of trees and earth and sand. The arm is operated to move the bucket backward while relaxing the inclination angle of the bucket, and the tree is moved from the bucket to the transplanting site.

In addition, in conventional tree transplanting work, when forming a digging groove around the tree to be transplanted, the arm of a heavy machine is operated to move the tip of the sharp rod-like body in plan view around the root of the tree. Thus, an approximately U-shaped digging groove was formed (for example, see Patent Document 1).

  However, in the above-described conventional tree transplanting work, after excavating the tree with the bucket of the tree transplanting machine, only the tree was transferred to the loading platform of the transport truck and transported to the transplanting site. At the time of transfer or transportation, the soil at the root of the tree collapses, the tree does not root well at the transplanting site, and the tree may die.

  In addition, in order to prevent the collapse of the soil at the root of the tree, it is necessary to cover the soil at the root of the tree when transferring to the loading platform of the transport truck, and this sheet must be removed when transplanting the tree. In other words, a great amount of labor, time, and cost were required for the operation of covering and removing the sheet.

  Moreover, in the above conventional tree transplanter, in order to perform the transplantation work using the weight of the tree to be transplanted and the earth and sand adhering to the root, the arm of the heavy machine is checked while the operator confirms the state of the tree in the transplantation work. It was necessary to move the bucket toward the rear while relaxing the inclination angle of the bucket by operating.

  Therefore, in the transplanting operation using the conventional tree transplanter, the operator requires skill and the transplanting operation requires a lot of time and labor.

  Further, in the conventional tree transplanting work, a dug groove is formed around the root of the tree by operating the arm of a heavy machine to move the tip of the sharpened rod, so that the root of the tree or When stones exist, it was difficult to form a digging groove smoothly.

  Therefore, in the conventional tree transplanting work, the operator requires skill and the work requires a great deal of time and labor.

Therefore, in the present invention according to claim 1, in a tree transplanting method in which a tree is dug from the root and transplanted to another place, a dug groove is formed around the root of the tree using a dug groove forming machine. Groove formation process, tree excavation process for digging trees with earth and sand at the root using a tree transplanter that connects the bucket with the front and upper open to the arm of the heavy machinery, and separating the bucket from the arm of the heavy machinery A tree transporting step for transporting the tree to the transplanting site while the tree is placed on the bucket together with the soil at the root, and connecting the bucket to an arm of a heavy machine, and using the bucket to transfer the tree to the transplanting site using the bucket and a tree transplant implanting with the drilling Tomizo forming step, the opening and closing around a shear blade of a pair of scissors to open and close the left and right on the tip of the heavy equipment arm to the right or left from the distal end of the arm Using excavation Tomizo forming machine provided by et, it was Rukoto to form a photo-groove immediately behind the trees by raising and lowering the arm laterally of the trees to be transplanted.

  And in this invention, there exists an effect described below.

That is, in the present invention, in the tree transplanting method of digging a tree from the root and transplanting it to another place, a digging groove forming step of forming a digging groove around the root of the tree using a digging groove forming machine; A tree excavation step of digging a tree together with the earth and sand of a root using a tree transplanter in which a bucket whose front and upper sides are opened is connected to an arm of a heavy machine, and the bucket is separated from an arm of a heavy machine, A tree transporting process for transporting a tree to a transplanting place while being placed together with the earth and sand of the root, and a tree transplanting in which the bucket is connected to an arm of a heavy machine, and the tree is transplanted to the transplanting site using the bucket with the earth and sand of the root. Therefore, the tree can be transported to the transplanting place with the dug out tree placed on the bucket together with the earth and sand of the root part. Without sand is lost, the trees implantation site can be implanted with sediment roots, trees and can be satisfactorily take root in the implantation site.

  Moreover, since the soil at the root of the tree is protected by the bucket at the time of transportation, it is not necessary to separately cover the soil at the root, and the labor, time and cost required for the tree transplanting operation can be reduced.

Further, in the present invention, since there is a digging groove forming step for forming a digging groove around the root of the tree using a digging groove forming machine before the tree digging process, Trees can be easily dug together with the soil at the root in the harvesting process, and this also reduces the labor and time required for tree transplanting work.

Further, the dug groove forming machine is provided with a pair of hook-shaped shearing blades that open and close at the tip of the arm of the heavy machine with the opening and closing center being biased to the right or left from the tip of the arm. Even if there are roots or stones around the tree to be cut, it can be broken with a shearing blade, and a digging groove in a tree transplanting operation can be easily formed. Also, since the digging groove can be formed right after the tree by raising and lowering the arm of the heavy machinery on the side of the tree to be transplanted, the arm collides with the tree when the digging groove is formed and the tree is damaged Can be prevented in advance.

  The tree transplanting method according to the present invention is a method of excavating a tree from the root and transplanting it to another place, and has the following steps.

(1) Digging groove forming process Using a digging groove forming machine, digging grooves are formed around the root of the tree.
(2) Tree excavation process A tree is dug together with the soil at the root using a tree transplanter in which a bucket whose front and upper sides are open is connected to an arm of a heavy machine.
(3) Tree transporting process The bucket is separated from the arm of the heavy machinery, and the tree is transported to the transplanting site using the transporting truck while the tree is placed with the earth and sand of the root in the separated bucket.
(4) Tree transplanting process The bucket is connected to the arm of a heavy machine, and the tree is transplanted together with the soil at the root to the transplanting site using the connected bucket.

  As described above, in the tree transplanting method according to the present invention, since the tree is transported to the transplanting place while the excavated tree is placed on the bucket together with the earth and sand of the root, the root of the tree is transported at the time of transportation. There is no collapse of the earth and sand, the tree can be transplanted to the transplanting site together with the soil at the root, and the tree can be well rooted at the transplanting site.

  Moreover, since the soil at the root of the tree is protected by the bucket at the time of transportation, it is not necessary to separately cover the soil at the root, and the labor, time and cost required for the tree transplanting operation can be reduced.

  In addition, since there is a digging groove forming step that forms a digging groove around the root of the tree using a digging groove forming machine before the tree digging process, Can be easily dug together with the soil at the root, and this also reduces the labor and time required for tree transplanting work.

  Further, the tree transplanter used in the above-described tree transplanting method is provided with sliding walls that slide back and forth along the left and right side walls and the bottom wall of the bucket inside the bucket, and slides the sliding wall back and forth. The sliding mechanism is connected to the sliding wall.

  Therefore, by sliding the sliding wall forward using the sliding mechanism, the tree placed on the bucket can be smoothly moved from the bucket to the transplanting site together with the soil at the root, so that the skill of the operator can be improved. This eliminates the need for labor and time required for transplantation.

  Moreover, since the sliding wall slides inside the bucket, there is no member that moves along with the movement of the sliding wall outside the bucket, and there is a danger that the worker may be injured by the member that moves outside the bucket. Therefore, the safety of transplantation work can be improved.

  In particular, when a bucket is connected to the tip of an arm of a heavy machine via an attachment and the sliding mechanism is supported by this attachment, and the bucket, the attachment, and the sliding mechanism are detachable, only the bucket is attached and Since it can be separated from the sliding mechanism, it is possible to transport the trees with the buckets with the trees still placed on the buckets, and transfer the excavated trees to the transport truck or from the transport truck to the bucket This eliminates the need for work, which can also reduce the labor and time required for transplanting work, and can prevent the collapse of earth and sand that occurs when replacing trees.

  In addition, when the attachment has a horizontal rotation mechanism that horizontally rotates the bucket, a left and right swing mechanism that swings the bucket left and right, and a front and rear swing mechanism that swings the bucket back and forth Even if the installation site of heavy machinery is sloping ground, or even if the digging location of trees or the transplanting location is sloping land or narrow land, the posture of the bucket can be optimized by the attachment, so excavation work and transplanting work Thus, the labor and time required for transplantation can be reduced.

  Further, the digging groove forming machine used in the tree transplanting method is provided with a pair of hook-shaped shearing blades that can be opened and closed in the direction perpendicular to the arms at the tip of the arm of the heavy machinery.

  Therefore, even if there are roots or stones around the tree to be transplanted, it can be broken with a shearing blade, and a digging groove in the tree transplanting operation can be easily formed.

  In particular, when the opening and closing center of the shearing blade is biased from the tip of the arm in a direction perpendicular to the arm, a dug groove is formed immediately after the tree by raising and lowering the arm of the heavy machinery on the side of the tree to be transplanted. Therefore, it is possible to prevent the arm from colliding with the tree and damaging the tree when the digging groove is formed.

  In addition, when the shearing blade is connected to the tip of the arm via a horizontal rotation mechanism, the tree to be transplanted can be transplanted only by rotating the shearing blade by the horizontal rotation mechanism without moving the heavy machinery itself when forming the digging groove. A digging groove can be formed in the periphery, and the digging groove forming operation can be facilitated.

  As shown in FIG. 17, a connection mechanism 130 attached to the tip of the arm 103 of the heavy machine 102 is detachably connected to the connection joint 122.

  In this way, the digging groove forming machine 101 is attached to the tip of the arm 103 of the heavy machine 102 via the attachment 105 having the horizontal rotation mechanism 121 and attached to the tip of the arm 103 of the heavy machine 102. A pair of bowl-shaped shearing blades 109, 110 can be opened and closed in a direction perpendicular to the arm 103, and the rotation shaft 111 of the shearing blades 109, 110 is attached to the left side of the base body 106, while the attachment 105 is attached to the right side of the base body 106 Thus, the open / close centers of the shearing blades 109 and 110 are biased in the direction orthogonal to the arm 103 from the tip of the arm 103.

  Then, the digging groove forming machine 101 moves the shearing device 104 to a predetermined position by operating the arm 103 of the heavy machine 102 as shown in FIG. 24 (see FIG. 24A). The shear blades 109 and 110 are opened and pressed perpendicularly to the ground 131 (see FIG. 24B), and then the shear blades 109 and 110 of the shearing device 104 are pressed against the ground 131 and closed (FIG. 24C). As a result, a digging groove 133 is formed around the tree 132.

  As described above, in the digging groove forming machine 101, the pair of shear blades 109 and 110 are provided at the tip of the arm 103 of the heavy machine 102 so as to be openable and closable in a direction perpendicular to the arm 103. Even if there are roots, stones, or the like on the surrounding ground 131, they can be broken by the shearing blades 109, 110, and the digging groove 133 in the tree transplanting operation can be easily formed.

  Further, in the digging groove forming machine 101, since the opening and closing centers of the shearing blades 109 and 110 are biased in the direction orthogonal to the arm 103 from the tip of the arm 103, as shown in FIG. By raising and lowering the arm 103 of the heavy machine 102 on one side, it is possible to form a digging groove 133 immediately after the tree 132, so when the digging groove 133 is formed, the arm 103 collides with the tree 132 and the tree 132 is damaged. This can be prevented in advance.

  In the digging groove forming machine 101, since the shearing blades 109 and 110 are connected to the tip of the arm 103 via the horizontal rotation mechanism 121, the heavy machinery 102 is not moved when the digging groove 133 is formed. The digging groove 133 can be formed around the tree 132 to be transplanted only by rotating the shearing blades 109 and 110 by the rotation mechanism 121, and the forming operation of the digging groove 133 can be facilitated.

  Next, the tree transplanting method according to the present invention will be described. In the tree transplanting method according to the present invention, the heavy machine 2 of the tree transplanting machine 1 and the heavy machine 102 of the digging groove forming machine 101 may be the same or may be used separately. Good.

  In the tree transplanting method according to the present invention, first, the soil in front of the tree 151 to be transplanted is removed using the tree transplanter 1 (see FIG. 25 (a)).

  Next, using the digging groove forming machine 101, digging grooves 152 are formed on the left and right sides and the rear side of the tree 151 (see FIG. 25 (b)).

  Next, the debris and roots below the tree 151 are cut using the digging groove forming machine 101 (see FIG. 25 (c)). Thus, the excavation groove 152 is formed around the tree 151, and the debris and roots below the tree 151 are cut, so that the tree 151 is separated from the ground, and the next excavation work is performed. Becomes easy.

  Next, using the bucket 4 of the tree transplanter 1, the tree 151 is dug together with the soil and sand 153 at the root (see FIG. 25 (d)).

  Next, the bucket 4 is separated from the arm 3 of the heavy machine 2 of the tree transplanter 1, and the tree 151 is placed on the platform of the transport truck 154 in a state where the tree 151 is placed together with the earth and sand 153 at the root. It is transported to the transplantation site by the transport truck 154 (see FIG. 25 (e)).

  Next, the bucket 4 placed on the loading platform of the transport truck 154 is connected to the arm 3 of the heavy machine 2 to form the tree transplanter 1, and the tree transplanter 1 is used to transplant the tree 151 together with the soil and sand 153 at the root. (See FIGS. 25 (f) (g)).

  As described above, the tree 151 can be transplanted to another location.

  In the above-described tree transplantation method, the tree 151 is transported to the transplanting site while the dug-out tree 151 is placed on the bucket 4 together with the soil and sand 153 at the root. Therefore, the tree 151 can be transplanted together with the soil 153 at the root portion, and the tree 151 can be well rooted in the transplant site.

  Moreover, since the earth and sand 153 at the root of the tree 151 is protected by the bucket 4 during transportation, there is no need to separately cover the earth and sand 153 at the root, reducing the labor, time and cost required for transplanting the tree 151. can do.
