Description

Fruit-tree cutter {Fruit-tree cutter}

The present invention relates to a cut peel cutter for fruit trees, and more specifically, the cut peel for fruit trees configured so that the distance between the knife stem and the cutting blade can be easily adjusted so that the cut skin of a fruit tree can be simply and conveniently cut according to the diameter of the fruit tree. It's about the cutter.

In general, farms and orchards that grow fruits use osmotic pressure to grow fruit trees such as persimmons and vines and increase the harvest.

The farming method using osmotic pressure cuts the cuticle at any one point in the stem (branch) of the fruit tree to raise the sap of the root to the cut point, and the elevated sap is supplied to the stem (branch) again, thereby circulating the sap of the fruit tree. It is a farming method that speeds up

In addition, in the fruit tree where the fruit is opened, various insects (pests) that use the sap of the fruit tree as a nutrient source hibernate in the outer bark of the fruit tree. By accelerating the growth and hastening the harvest, it increases the yield and prevents damage to the cultivation caused by insects in advance.

In order to use the farming method using such an osmotic action, the stem of an orchard can be partially cut using pruning shears as in Korean Patent Application Laid-Open No. 10-2011-0001684;

The above-described pruning shears have a straight blade, so if force is applied while the stem is biting the stem of the fruit tree, the stem is pushed back due to the pressed knife, making it difficult to partially cut while drawing a circle along the outer circumferential surface of the stem.

In order to compensate for this problem, two arc-shaped knife blades are cross-connected to meet each other as shown in Korean Patent Application Laid-Open No. 10-2017-0137296; configured to be able to.

However, according to the principle of lever, one of the two blades that are cross-connected to bite the stem is used to bite and fix the stem. In order to cause the phenomenon, the cutting scissors must be rotated 360 degrees (°) once while the knife is biting the stem to cut the outer circumferential surface and the inner skin of the stem, which is inconvenient to work.

In addition, although the stem is bitten by the principle of a lever by applying an appropriate force, there is a problem in that the cutting operation is not performed correctly because the stem is not properly fixed depending on the skill level of the operator during the rotation of the cutting scissors.

In order to solve the above problems, the present invention not only allows the outer skin and inner skin of a fruit tree to be cut quickly, but also conveniently adjusts the distance between the blade and the cutting blade and the angle of the cutting blade according to the diameter of the fruit tree. Accordingly, an object of the present invention is to provide a cutting machine for fruit trees that can cut the cuticle of a fruit tree, thereby greatly improving the efficiency of cutting the cuticle of a fruit tree.

The cuticle cutting machine for fruit trees of the present invention for achieving the above object is configured such that two knife parts cross-connected by a hinge can be selectively coupled to two or more hinge holes, and one knife part bites a branch of a fruit tree The inner saw blade part and the blade part for cutting the outer skin and inner skin are formed, and the other knife part has a blade that can be adjusted and replaced when worn out. The present invention is characterized in that it is configured to be able to cut the outer skin and inner skin by rotating it about 180 degrees, which is half a turn in one direction.

The cuticle cutting machine for fruit trees of the present invention has the advantage of being able to cut the cuticle to an appropriate depth by adjusting the angle of the blade according to the diameter of the fruit tree because the blade is configured to be replaced and the angle can be adjusted on one knife part.

In addition, there is an advantage that can be used by quickly adjusting the gap between the blade part of the cutter according to the diameter of the fruit tree because the two knife parts can be opened and closed by the hinge hole.

Hereinafter, to be described in detail with respect to the fruit cuticle cutting machine for fruit trees of the present invention, these descriptions are based on the embodiments for implementing the present invention, and the technical idea pursued by the present invention is described in the embodiments described in this document. It is not intended to be limited in form, and it should be understood to include various modifications, equivalents and/or alternatives of the embodiments of the present invention.

In addition, although the effects of the configuration of the present invention are not explicitly described and described while describing the embodiments of the present invention, it is natural that the effects predictable by the configuration should also be recognized.

The cutter (1) of the present invention is composed of two knife parts (10, 20) cross-connected by a hinge (2) and handles (10-1, 20-1) extending with the knife part, the hinge ( 2) is connected to be selectively coupled to two or more hinge holes 3 and 3-1.

A saw blade portion 10-2 for biting the fruit tree and a blade portion 10-3 for cutting the cuticle are formed in the one knife portion 10, and the position of the knife blade 30 in the other knife portion 20 is coupled to the shaft 31 so that it can be adjusted and replaced, and the adjusting screw 32 is fastened to the fixing part 33 so that the blade 30 can move at a predetermined angle around the shaft 31, The end of the adjusting screw is configured to be coupled to the long groove (30-1) of the blade (30).

Reference numeral 50 in the drawings denotes a torsion spring.

Looking at the action of the cuticle cutting machine for fruit trees of the present invention configured as described above is as follows.

The operator feeds the cutter (1) to the fruit tree or branch to cut the cuticle (B). (10) and (20) can be placed on a tree trunk or branch.

When the two knife parts 10 and 20 are put into the fruit tree stand or branch and the handles 10-1 and 20-1 are cut, the saw blade part 10- that bites the fruit tree in one knife part 10 2) and the blade part 10-3 for cutting the cuticle bite the fruit tree stem or branch, and the blade 30 on the other knife part 20 is also bitten by the fruit tree branch or branch.

In the same state as described above, if you hold the handles 10-1 and 20-1 of the cutter 1 and rotate the cutter 1 in either direction about 180°, the saw blade part 10-1 and the blade part 10- 3), and the blade 30 rotates along the outer circumferential surface of the fruit tree to cut the cuticle of the fruit tree, causing an osmotic pressure phenomenon.

As described above, when the two knife parts 10 and 20 constituting the cutter 1 are put into the fruit tree stand or branch, and the diameter of the fruit tree is large, the hinge 2 is moved toward the hinge hole 3-1. When moving and moving toward the hinge hole (3) when the diameter is small, the gap between the two knife parts (10) (20) is widened or narrowed.

In addition, when the diameter of the fruit tree is large or small, when it is necessary to adjust the angle at which the blade 30 touches the skin of the fruit tree, tighten or loosen the adjustment screw 32 fastened to the fixing part 33. It works with the long groove 30-1 coupled to the end so that the blade 30 moves at a certain angle around the shaft 31, so it can be used by adjusting it to an appropriate angle.
