Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem: a work for fixing a side branch of pear to a trellis requires a long time and skill, especially when the branch is thick and strong, technique for twisting and bending the branch without breaking the same is limited to specific workmen and efficiency of the work has not been good. <P>SOLUTION: In a tool for bending branches, a vertical split is made in a part of the side branch to be bent on one of action units of the tool having L shaped action units and a blade 1 is fixed in a cross-shaped form. The branch is easily bent and fixed to the trellis by simultaneously acting splitting force and twisting force to the bent part of the side branch by using the boosted force of the tool. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a branch bending tool used when bending branches of fruit trees such as pears, apples, peaches, and grapes at appropriate locations and guiding them to a shelf and fixing them.

So far, this type of branch bending has been proposed that has a pinching type, a pressing blade composed of a plurality of semicircular blades on one side of the pinching tip of the pruning tool, and an L-shaped branch receiving portion on the other side. It was. This branch-bending tool bends without breaking the branch by sandwiching the branch between the pressing blade and the branch receiving portion, scratching the bark of the branch with the pressing blade and twisting at the same time.
Utility model registration No. 3109773

Problems to be solved by the invention

  However, in the pinch-type pruning tool, the length of the gripping tool is short and the force is transmitted to the tip, that is, the degree of the boost is about 2 to 3 times, and the 10 mm thin branch can be bent without any trouble, Bending a thick branch having a thickness of about 20 mm to 30 mm in the horizontal direction requires a considerable amount of twisting force, and repeating the branch bending work has a problem of increasing the physical fatigue of the operator.

Means for solving the problem

  The present invention provides a branch bending tool that solves the above-mentioned problem, and a tool having a substantially L-shaped working portion at the tip, for example, a water pump pliers and finally a pair of tool bodies, A U-shaped or arcuate blade is fixed, for example, welded to at least one of the working parts so as to cross the cross. The side branch of the pear is about 10 mm to 30 mm, and when it gets thicker, it requires a considerably strong force for bending and requires a high boosting power. The tool is bitten into the working part of this tool to a depth of 1/2 to 1/3 of the diameter of the branch with a blade width of 20 mm to 30 mm so that the branch breaks vertically, so that it can be twisted and bent. In addition, a blade having a width of about 50 mm to 60 mm is attached to the action portion in a cross shape.

The invention's effect

  The side branch of the pear can be fixed by tilting a thin object on the shelf sufficiently by hand, but when laying down a thick and strong branch, place the blade vertically at the place where you want to bend it, squeeze the tool, and bite the blade. By splitting a part of the branch vertically, it can be bent easily and twisted. At the end of branch bending, this tool is placed in the waist bag, so you can carry it quickly without hindering you from carrying it.

  The pear side branch extends straight up to 1m to 2m on the shelf. There are a lot of shelves with iron wires stretched from 400mm to 500mm in height about 1.8m above the ground. There is an operation to tilt the standing side branch 90 ° horizontally on the shelf and fix it with a string so that it is almost horizontal to the shelf before the flower buds open. The branch bending tool of the present invention is one that performs this work efficiently. There are various thicknesses of pear side branches, but since the thickness that can be used to produce fruit is up to about 25 mm, it is a thick and strong branch that is difficult to bend. If the branch is interrupted and twisted so that it will not break or break, it can be fixed to the shelf without damaging the branch.

  It can be used not only for pear branching but also for other fruit trees, garden trees, and bonsai trees.

    As pear producers have increased the cultivation area, labor-saving is required, which is used as a tool for that purpose.
