JP4392841B2 - Tree pruning method and saw storage case used in the method - Google Patents

Description

  The present invention relates to a method for pruning trees such as cedar or firewood using a saw, and a saw storage case used in the method.

The pruning of cedars, bushes, etc. is to cut off unnecessary sprigs, but this pruning work is necessary to obtain a stand-free tree without bending. This pruning operation is generally performed by using a saw or a saw, and in the case of pruning using a saw, the sap (hereinafter referred to as “sap”) may be applied to the tooth portion of the saw and its surroundings. )), Adheres frequently to long-time work, and during continuous work, once the work is rested and left unattended for a while, the attached eye will harden and the next pruning work is performed. The saw's street was not good and the work efficiency was extremely deteriorated.
In the past, in order to remove the slag adhering to the saw, for example, it was rubbed with a twig. In general, there has been proposed a saw that hardly adheres to the surface of the saw (see, for example, Patent Document 1).
JP-A-11-179702

Since pruning work is often performed on the tree, it is desirable to perform as many pruning as possible once it has been climbed on the tree. Scrubbing with, for example, greatly reduces work efficiency, but it is also a reality that there was no other suitable method.
The present inventor has been engaged in mountain forestry and has been pruning for many years, but there was no better method than the method of rubbing the slag attached to the saw with the above-mentioned twigs. I was worried about the improvement. And it succeeded in the removal as soon as it adhered by the method as described below very easily.

  The invention according to claim 1 of the present invention, when performing pruning of trees such as cedar or oak using a saw, put water into a cylindrical case in which one end for housing the saw is closed watertight, A first stage in which a pruning operation is performed using the saw, and a second stage in which the saw is housed in the cylindrical case and the tooth portion of the saw is immersed in the water after the completion of the first stage; A tree pruning method comprising: after the second stage, a third stage for extracting the saw prior to the next pruning, and repeating the first stage, the second stage, and the third stage a plurality of times It is.

  As described above, one end of the case for storing the saw is made watertight, water is put in the case in advance, and the saw tooth part is in contact with the water by storing the saw in the case each time the saw is used. Moisture adheres to the tooth part of the saw, and then the saw is taken out as it is, and when the work is performed, the tooth attached to the tooth part is rubbed more easily than before and falls or is shredded. It turns out that it sticks to the cut surface of a standing tree.

  The reason why the adhesion can be easily removed in this way is presumed to be a result of the interaction between moisture and the scraping by the reciprocating movement of the saw.

The invention according to claim 2 of the present invention is a cylindrical case used in the implementation of the method according to claim 1, characterized in that one end is closed in a watertight manner and the other end is opened to allow the saw to enter and exit. This is a saw storage case.

  There have been cases for storing saws, but there was a relatively large opening at the bottom as well. Although this seems to be the removal of dust or better drainage, the present invention is rather characterized by retaining water in the case.

  In the invention according to claim 3, a wide belt loop is provided on the flat surface side of the cylindrical case whose at least one outer surface is a substantially flat surface, and on the side where the saw is removably opened. The saw storage case according to claim 2.

  In general, the saw storage case is held through the trouser belt, but in the present invention, water is retained so that it must be kept as stable as possible during work. Is made to be a substantially flat surface and the belt loop is wide to prevent the case from rotating.

As can be seen from the above description, the present invention can efficiently remove the adhering to the tooth portion of the saw when pruning a tree such as cedar or firewood using a saw. Was able to increase to about twice. In addition, a solution for that is sufficient to improve the conventional saw housing case slightly, and the effect of the present invention is extremely great.

  An embodiment of the present invention will be described with reference to the drawings. 1 is a perspective view of an example of a saw storage case and a saw used in the implementation of the method of the present invention, FIG. 2 is a side view of the case and a part of the saw, and FIG. 3 is a partially enlarged view of the case. FIG. 4 is a partially enlarged perspective view of another example of the case, and FIGS. 5 and 6 are views showing examples of the cross-sectional shape of the case.

  1 and 2, 1 is a case body for storing a saw, 2 is a saw, 3 is an open end of the case body 1 for inserting and removing the saw, 4 is a watertightly closed end opposite to the open end, 5 Is a belt loop, and 6 is a belt.

  Each time the pruning operation is completed, the saw 2 is accommodated in the case body 1. Since an appropriate amount of water 12 is placed in the case body 1, for example, about half of the case, the tooth portion 7 of the accommodated saw 2 is stored. Almost the lower half including the water is immersed in water. In this case, the tooth 2 of the saw 2 and its periphery are attached to the periphery.

  Next, the saw 2 is taken out from the case body 1 and the next pruning operation is performed. At this time, the teeth 7 attached to the saw 2 and the periphery thereof are easily scraped with the reciprocating motion of the saw. The saw street is very good.

  It is estimated that the removal of the slag is a result of the interaction between moisture and the scraping by the reciprocating movement of the saw.

  3 and 4 are perspective views showing examples of attachment of the belt threading 5 and the opening end 3 side of the case, respectively, and FIG. 3 shows that the belt threading end 8 is firmly bonded to the opening end 3 side with a tape 9 or the like. FIG. 4 shows an example in which the end portion 8 is fixed to the opening end 3 side with a rivet 10. However, when stopping with a rivet, in order to prevent damage to the tooth portion of the saw, the rivet fitting should not be exposed inside the case body. Although not shown, the belt loop and the case main body can be integrally molded.

  FIGS. 5 and 6 show examples of cross-sectional views of the case body 1. In FIG. 5, the side 11 in contact with the trousers is flat, and in FIG. 6, the side 11 in contact with the trousers is slightly bent. Yes.

  These are all flat and prevent rotation when the case is attached to the pants so that the case body 1 can be held as stably as possible.

  The amount of water to be put into the case body 1 is not particularly limited, but it was convenient to put water up to about half of the case height. Further, the shape of the case body 1 is not limited to the illustrated example, and various shapes can be adopted, and the opening end where the saw enters and exits can be made wide and the closed end can be made narrow so as to facilitate the entry and exit.

It is a perspective view of an example of the case for saw storage used in implementation of the method of the present invention, and a saw. It is a partially cutaway side view of an example of a saw storage case and a saw. It is a partially expanded perspective view of the same case for saw storage. It is a partially expanded perspective view of the other example of the case for saw storage. It is a figure which shows an example of the cross-sectional shape of the case for saw accommodation same as the above. It is a figure which shows the other example of the cross-sectional shape of a case for saw accommodation same as the above.
