Description

[0001]
BACKGROUND OF THE INVENTION
For forest management, thinning and thinning operations are essential. Conventionally, trees have been felled for this thinning and thinning, but this invention does not cut down, but cuts and peels off part of the bark of unnecessary trees, prevents the flow of sap, and remains as a standing tree. The present invention relates to a tree wiping machine that does not require dangerous work and can easily achieve the same effect as thinning and thinning.
[0002]
[Prior art]
The conventional thinning and thinning operations are carried out with a chain saw or saw, but this requires skill and skills, and the work site has many steep places, so when falling over or falling over trees. There are also dangers such as bruises caused by rebounding trees and underlaying trees, and occupational accidents have also occurred.
In addition, it takes time to cut the standing tree, and it often gets caught on the adjacent tree branch when the tree is knocked down. Cost.
Recently, although the price of timber is low, the cost of carrying out is high and it is not possible to make a profit for the use of timber. Therefore, the harvested timber is often left in the forest without being carried out.
For these reasons, many experts have recently recommended rolling thinning as a method of thinning and thinning.

Soya Valley New Thinning Manual = National Forestry Improvement Dissemination Association issued (November 12, 2002, first edition)
However, this method uses a saw, chain saw, scissors, sickle, etc. to wrap around the trunk and cut several horizontal lines on the trunk, or to peel off the skin more than 1 meter, all of which are hands. We carry out by work.
Moreover, in order to carry out this work, it is necessary to go around two or more times while manually working around the tree before the work of one standing tree is completed. In addition, because the mountainous area has many slopes, you have to work up and down, which is inefficient, time consuming, and requires physical strength and skills.
In addition, when working on an inclined land, it is necessary to use a saw or a firewood with one hand while holding a tree trunk with one hand, which is dangerous and causes occupational safety and health problems.

[0012]
DETAILED DESCRIPTION OF THE INVENTION
The working period by the dehuller of the present invention is the period when the sap of the tree is flowing, and the period between the bark of the tree and the formation layer is in a free state due to the flow of the sap and is easily peeled off. The work period. Therefore, the implementation operation of the present invention will be described.
[0013]
Stand in front of the tree to stand up. At this time, if the site is sloping, stand with the mountain side as the back. Next, the presser bar 5 of the skin cutter A of the present invention and the presser foot 5 of the skin cutter B are held with both hands, and the tip is expanded toward the tree as shown in FIG.
[0014]
Continuing pressed against the front of the trunk, at the same time the previous as semicircular serrations saddled the trunk from the right and left skin switching device A and peel Setsugu B intersect, because it does not revert by strike Tsu par 6, this machine trunk Stick to.
[0015]
While holding the presser bar 5, the bark is simultaneously cut in two stages with a saw blade by repeating a reciprocating operation half a turn back and forth and back and forth around the tree trunk.
In this case, although the cutting diameter of the tree trunk is gradually reduced, the saw blade bites toward the center of the tree trunk by the stopper 6 by the reciprocating operation, so this machine is always attached to the tree trunk stably in a horizontal line shape.
[0016]
When the bark portion can be cut, the tips of the bark 8 and the barb 9 are pushed out to the trunk side with fingertips, respectively, so that the blade at the tip of the bark adheres to the bark surface.
[0017]
Next, when the machine is rotated in one direction, the blade at the tip of the bark cuts into the bark layer, enters the formation layer between the bark and wood, and pushes open the bark. Leaves. At this time, the other peeled cocoon does not dig into the bark but is spinning up and slipping.
Subsequently, when this is rotated in the reverse direction, the tip of another peel barb enters the formation layer, and the remaining bark is peeled off, so that the bark of the full circle can be peeled.
[0018]
When the peeling is finished, the tip of the spring-operated stopper 6 and the skin cutting tool B comes off by pulling the hand of the stopper operating bar 13, and when the machine is pulled forward, the tips of the skin cutting tool A and the skin cutting tool B are removed. Opens, the machine can be removed from the trunk, and the peeling process of the tree ends.
[0019]
The bases of the peeler 8 and 9 are in contact with the U-shaped spring as shown in FIG. 4, and the tip of the peeler is directed inward by crossing the peak of the U, Can face outward.
[0020]
The spring-shaped springs 10 and 11 are for the tip of the skin peeler to fold inwardly and outwardly. It is possible to make a folded state.
[0021]
When the skinning process is completed, as shown in FIG. 6, the key portions at the tips of the rewinding devices 14 and 15 are located outside the base portions of the skinning reeds 8 and 9, and the rewinding devices 14 and 15 Is in a state where the fulcrum is at the base of the opposite skin cutting tool.
For this reason, the skinning process is completed and the tips of the skin cutters A and B are opened, and at the same time, the key portions at the tips of the rewinding devices 14 and 15 hook and pull the base portions of the skinning scissors 8 and 9, and When the tips of the skin-cutting tools A and B are opened widely, the bases of the skinning rods 8 and 9 pass over the piles of the springs, respectively. Therefore, as shown in FIG. When the state is changed to the next work place, the above-described execution operation [0013] can be started immediately.
[0022]
When the present invention is used, the stopper 6 is removed after the operation of the above-mentioned execution operation [0015], the position is shifted above or below the cutting position of the trunk, and the tree 6 is pressed against the trunk again to perform rotational reciprocation. . By performing this position shifting operation several times, it is possible to achieve the effect of thinning withering.
[0023]
The wide cutting groove can be cut in the horizontal line shape of the trunk by widening the width of the saw blades arranged in a semicircular shape of the present invention or by making the saw blade thick.
[0024]
By attaching an auxiliary bar to the support bar 5 in order to increase the diameter of the rotational motion, it is possible to easily apply a cutting work force.
[0025]
When the tree is erected, it has been proved that the bark will die if the cut-peeling interval of the vertical width of the bark is 15 cm or more. Therefore, it has been found that the interval between the saw plate 1 and the saw plate 2 is based on this.
[0026]
From this fact, if two years have passed since the use of the withering and peeling machine according to the present invention, the tree will naturally wither, so that the same effect as thinning after thinning can be obtained.
[0027]
【The invention's effect】
Since this invention is comprised as mentioned above, there exist the following effects.
[0028]
When using this machine, even on a sloping ground, the skinning operation can be performed while standing on the mountain side of the standing tree, so the scaffolding is stable and safe without falling over during work.
[0029]
In the present invention, the entire circumference of the bark can be peeled off by a reciprocating operation of the left and right by half rotation, so that even a beginner can finish work easily, quickly and safely without requiring any special technique.
[0030]
When operating this machine, the part of the cutting tool such as the saw blade is always on the opposite side of the worker's body, and there is almost no part in contact with the body so that the work is safe.
[0031]
In addition, since the only parts that can be touched during operation are the stopper operating bar 13, the peeler 8 and the peeler 9 in addition to the support bar 5, there is almost no danger during operation.
[0032]
Since the distance between the saw plate 1 and the saw plate 2 and the distance between the saw plate 3 and the saw plate 4 are not so wide, the shape is small and the structure is simple, so there are few lost parts and the forest is light. Work on site is easy.
[0033]
Since this machine is lightweight and can usually hold the connecting shaft 12 with one hand, it is easy to carry and move at the work site.
[0034]
Since the basic structure of the structure of the present invention is to stack identical steel plates, the manufacturing process is easy to simplify.
[0035]
If the diameter of the trunk of the standing tree is within the diameter of the semicircular sawtooth of the present invention, both large-diameter trees and small-diameter trees can be peeled off with the same machine, so it is possible to operate even in forests of forest phases with different diameter classes. is there.
[0036]
When operating the present invention, the front / rear / right / left action of holding the support bar 5 at the time of cutting the bark is the same rotation direction, pulling one hand and pushing the other hand, so a stronger force is applied in the same rotation direction. Because you can concentrate, work does not require much physical strength.
[0037]
The present invention is characterized in that since it does not use a power machine, it is lightweight and has a simple structure, so that it is inexpensive and can provide a high economic effect.
