Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a tree planting fixing device for fixing trees so that they do not fall over.

(Prior art) When securing a tree to prevent it from falling during planting, conventional techniques have been to attach multiple buffers to the tree 3 with the rootstock 1 housed in the planting hole 2, as shown in Figures 4 and 5. The wrapped wire rope 5 is twisted and wound with the material 4 interposed therebetween, and the ends of the wire rope 5 are connected by a tightening member or the like, and the wire rope 5 is tightened and installed. Then, a plurality of pulleys 6 are attached to the winding wire rope 5, and the pulleys 6 and the root stock 1 are attached to the winding wire rope 5.
A tension wire rope 8 is passed through and connected to the anchor bolt 7 driven into the soil outside, and the tension wire rope 8 is tightened by a ratchet tightener 9, and the pulley 6 is fixed to the anchor bolt by the tension wire rope 8. The tree 3 was fixed by pulling against the tree 7.

(Problem to be solved by the invention) However, since the wire ropes 5 and 8 are bundles of steel wires and are hard and lack bendability, they cannot be wrapped around trees 3 or inserted into pulleys 6 and anchor bolts 7. It was difficult and the workability was very poor. In addition, since the wrapping wire rope 5 has poor bendability, it is difficult to tighten it evenly and uniformly to the tree, and it is difficult to balance the force caused by the tension of the tension wire rope 8, making it difficult to securely fix the tree so that it does not fall. It was difficult to do so.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, an object of the present invention is to provide a tree planting and fixing device that can easily and reliably fix trees.

(Means for Solving the Problem) The technical means of the present invention for solving this technical problem consists of a winding belt 13 that is wound around a tree, and a first connection to which one end of the winding belt 13 is connected. Part 1
4, a bolt 16 that is inserted into the first connecting member 14 so as to be rotatable around its axis and is prevented from coming out by a retaining pin, and the other end of the wrapping belt 13 are connected and are screwed into the bolt 16 via a nut 34. The second connecting member 31
, a plurality of rings 37 inserted and held by the wrapping belt 13, and a tension belt 43 connected to the rings 37 and anchor bolts 38 driven into the soil outside the tree roots, The second connecting member 31 connects to the first connecting member 14 so that the nut 34 moves in the axial direction of the bolt 16 by rotation around the axis of the bolt 16 to adjust the ends of the wrapping belt 13 toward and away from each other. The point is that it is held so that it cannot rotate relative to the body.

(Function) When fixing the tree 3 during tree planting, first remove the other end of the wrapping belt 13 from the second connecting part 31, and then tighten the nut 34 and the second connecting member 31 as shown by chain lines in FIG. With the bolt 16 moved to the end, the wrapping belt 13 is wrapped around the tree 3 with a cushioning material 46 such as rubber interposed therebetween. Next, the other end of the wrapping belt 13 is connected to the second connecting member 31 via the stopper 33, etc., and then the bolt 16 is rotated to tighten the nut 34 and the second connecting member 31 to the head of the bolt 16. 39 side and tighten the wrapping belt 13 to the tree 3.

Then, the tension belt 43 is connected between the ring 37 and the anchor bolt 38, and the tension belt 43 is tightened using a tightening machine 44 or the like to pull the ring 37 toward the corresponding anchor bolt 38.

(Example) Hereinafter, the present invention will be explained according to the illustrated example. In Figs. 1 to 3, 13 is a wrapping belt to be wrapped around the tree 3, and the belt is made of polyester fiber and has a thickness of 2 mm to 3 mm. It is formed into a belt shape with a width of about 25 mm, and is constructed so that the belt breaking strength is 2500 Kgf or more.

Reference numeral 14 denotes a first connecting member made of metal, which has an insertion hole 15 at one end, and after inserting one end of the wrapping belt 13 into the insertion hole 15, it is folded back in half and the overlapped part is sewn. 22, thereby connecting one end of the wrapping belt 13 to the first connecting member 14. 16 is a bolt, which connects the first connecting member 14;
The first connecting member 14 is inserted through the mounting hole 17 so as to be freely rotatable about its axis, and the first connecting member 14 is sandwiched in the thickness direction between the collar body 19 on the head 18 side of the bolt 16 and the washer 20 fitted onto the bolt 16. In this state, by inserting and fitting a retaining pin (not shown) into the pin hole 21 of the bolt 16, the bolt 16 is prevented from being withdrawn from the first connecting member 14.

25 is a metal box integrally formed with the first connecting member 14, and has a storage chamber 26 inside.
Opening 27 at the end opposite to the first connecting member 14
is formed. Threaded shaft 28 of the bolt 16
is held within the storage chamber 26.

Reference numeral 31 denotes a second connecting member, which has an insertion hole 32 at one end, into which the other end of the wrapping belt 13 is inserted and folded back, and this overlapping state is held by a stopper 33. Accordingly, the wrapping belt 13
The other end is connected to the second connecting member 31. The second connecting member 31 is inserted into the storage chamber 26 of the box body 25 with the end portion on the side of the insertion hole 32 protruding outward from the opening 27, and is inserted into the storage chamber 26 of the box body 25 via the nut 34 to connect the threaded shaft 28 of the bolt 16. The second connecting member 31 is prevented from rotating around the threaded shaft 26 of the bolt 16 with respect to the first connecting member 14 by the box 25, and the second connecting member 31 is prevented from rotating around the screw shaft 26 of the bolt 16. By doing so, the nut 34 moves in the axial direction of the bolt 16 to adjust the end portions of the wrapping belt 13 toward and away from each other.

A plurality of delta rings 37 (approximately 4 to 6 delta rings) are inserted and held in the winding belt 13. A plurality of anchor bolts 38 are provided at intervals in the circumferential direction so as to surround the outer periphery of the root stock 1. These anchor bolts 38 are driven into the soil outside the root stock 1 in the planting hole 2, and have annular heads. 39 is protruding upward from the ground.

Reference numeral 43 denotes a tension belt, which is formed of polyester fiber into a belt shape with a thickness of about 2 mm and a width of about 25 mm, and is constructed so that the belt breaking strength is 1500 Kgf or more. Both ends of the tension belt 43 are inserted through and connected to the heads 39 of adjacent anchor bolts 38, and the center part of the tension belt 43 is connected to the ring 37.
By tightening the ratchet tightener 44 provided in the middle of the tension belt 43, each of the plurality of rings 37 is pulled against the corresponding anchor bolt 38, whereby the tree 3 is held at the root stock 1. It is designed to be fixed and held in an upright position when it is in the planting hole 2. Although not shown, a plurality of tension belts 43 are arranged radially around the tree 3.

In the above embodiment, the wrapping belt 13 and the tension belt 43 are made of polyester fibers, but instead, the belts 13 and 43 may be made of synthetic fibers other than polyester, steel, or the like.

(Effect of the invention) According to the invention, the wrapping belt 13 that is wrapped around a tree, the first connecting member 14 to which one end of the wrapping belt 13 is connected, and the first connecting member 14 that rotates around an axis. The bolt 16 is freely inserted and is prevented from being removed by a retaining pin, and the second connecting member 31 is connected to the other end of the wrapping belt 13 and is screwed onto the bolt 16 via a nut 34. The second connecting member 31 is connected to the first connecting member 14 so that the nut 34 moves in the axial direction of the bolt 16 by rotation around the axis of the belt 16 to adjust the ends of the wrapping belt 13 toward and away from each other. Since the wrapping belt 13 is held relatively unrotatable, the wrapping belt 13 is thin and bendable, so the wrapping belt 13 can be easily and securely wrapped around the tree 3. By rotating the belt 13, the belt 13 can be tightened evenly and uniformly around the tree 3.

Further, since it includes a plurality of rings 37 inserted and held by the wrapping belt 13, and a tension belt 43 connected to the rings 37 and anchor bolts 38 driven into the soil outside the roots of the tree, Since the tension belt 43 is also highly bendable, it can be easily connected to the anchor bolt 38 and the ring 37, and the ring 37 can be pulled by tightening with a tightening machine or the like, and the tree 3 can be held in tension evenly in a well-balanced manner. , the tree 3 can be easily and reliably fixed in an upright position without fear of falling. Moreover, the wrapping belt 13 and the tension belt 43
By constructing the rope from polyester or the like, there is less risk of corrosion compared to conventional wire ropes, and the tree can be firmly fixed for a long period of time, and its practical effects are significant.
