Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention applies to cuttings of cedar, cypress, etc.
This invention relates to a scion processing device for cuttings used to produce scions for cuttings.

"Prior Art" and "Problems to be Solved by the Invention" Generally, in order to root cuttings of cedar or cypress,
As shown in Figure 5, cut the shoots of cedar or cypress to a length of about 30 cm, remove the branches and leaves from the trunk about two-thirds from the bottom of the cut shoots, and make a scion. 19 (Fig. 5 B) and its scion 1
9 is inserted into the ground to allow it to take root.

However, in the past, there was no dedicated processing equipment for making scions, so the manual process of cutting branches and leaves one by one using scissors or knives to make scions was carried out.

Therefore, when producing a very large amount of scion wood for planting or afforestation, the processing work is extremely labor-intensive and extremely inefficient.

The purpose of the present invention is to solve the above-mentioned problems with the conventional processing means, and to provide a new processing device exclusively for making scion wood.

``Means for Solving the Problems'' The present invention achieves the above objects, in which a cylindrical cutting blade shaft is mounted inside a rotatable cylindrical main shaft so as to be slidable in the axial direction, and the cutting blade The head of the shaft is formed into a cutting edge portion with a saw blade shape on the peripheral wall, and
"A mantle tube part having a receiving blade which protrudes in the radial direction inside the latch-shaped guide part at the tip and which becomes a counterpart of the cutting blade part and constitutes a cutting mechanism" is fitted and fixed on the outside, and further, the cutting blade shaft is biased in the backward direction and has a locking groove formed on the outer periphery that is inclined with respect to the center line of the cutting blade shaft, and the locking pin of the main shaft is fitted into the locking groove. An interlocking means is provided which receives a thrust in the forward direction by the rotation of the main shaft and interlocks, and inserts a scion twig from the guide part into the hollow part of the cutting blade shaft, and It has a structure in which the receiving blade on the fixed side cuts off the branches of the scion twig.

"Example" and "Operation" Hereinafter, a detailed explanation will be given with reference to an example. Mazu,
Referring to FIGS. 1 to 5 showing one embodiment thereof, the scion processing device for cuttings of the present invention includes a main shaft 1 which is shaped into a hollow cylinder and is rotatable, and which is inserted into the hollow part of the main shaft 1.
It consists of a hollow cylindrical cutting blade shaft 2 with a cutting blade part 4 formed on the circumference of the tip, and a mantle tube part 3 that is fitted onto the tip of the cutting blade shaft 2, and the cutting blade shaft 2 is supported by a coil spring 5. and is forced backward (to the left in Figure 1),
It is designed to rotate in conjunction with the main shaft 1, as shown in Fig. 1D.
From the front opening of the mantle tube part 3, insert a scion twig 18 of cedar or the like (approximately 30 cm of the new bud part to make a scion).
When the cutting blade 4 at the tip of the cutting blade shaft 2 and the receiving blade 16 provided on the inner periphery of the tip of the mantle tube part 3 are inserted, the scion twigs 18 are branched. The tree is cut at the base of the trunk, allowing scion wood to be made.

Specifically, the main shaft 1 is mounted on a bearing 7 provided on a frame 6.
At the same time, an electric motor 8 and a belt 9 in a frame 6 are wound around it to form a freely rotatable hollow shaft. The cutting blade shaft 2 is inserted without play and can be slid freely in the axial direction,
The head of the cutting shaft 2 is formed with a cutting blade 4 whose peripheral wall is in the shape of a saw blade. It's becoming like that.

Then, slightly behind the cutting blade portion 4 of the cutting blade shaft 2,
A stepped portion 10 with an enlarged outer diameter is formed, and a coil spring 5 is interposed between the stepped portion 10 and a mantle tube portion 3, which will be described later, so that the cutting blade shaft 2 is biased in the backward direction. At the same time, an inclined locking groove 11 is formed on the intermediate outer periphery of the cutting blade shaft 2, making an angle θ to the center line 2' of the cutting blade shaft 2. And the locking groove 11
, the tip of a locking pin 12 is fitted onto the main shaft 1, and the rotation of the main shaft 1 is transmitted to the cutting blade shaft 2 via the locking pin 12, and the rotation is transmitted by the inclination angle θ of the locking groove 11. A thrust force for advancing the cutting blade shaft 2 against the biasing force of the coil spring 5 is generated by the component force caused by the rotation in the direction of the center line 2'.

On the other hand, the outer tube part 3, as shown in FIGS. 1 and 3, forms a tube body that fits over the tip of the cutting blade shaft 2, and has a guide part 13 with an enlarged diameter at the tip and a male thread at the rear end. The male threaded portion 14 is screwed into the mounting portion 17 of the frame 6, and the mantle tube portion 3 is integrally fixed to the frame 6. A step portion 15 is formed inside the mantle tube portion 3, and a coil spring 5 is interposed between the step portion 15 and the step portion 10 of the cutting blade shaft 2. It is designed to bias the body backwards. Further, a pair of radially protruding ridge receiving blades 16 are formed on the guide portion 13 of the mantle tube portion 3, and the mantle tube fixed to the cutting blade portion 4 of the rotating cutting blade shaft 2 is formed. The receiving blade 16 of the part 3 is configured to cut branches and leaves of the scion twig from the root of the scion.

In addition, when the cutting blade shaft 2 and the mantle tube part 3 are stopped, the cutting edge of the cutting blade part 4 is moved to the guide part 13 by the biasing force of the coil spring 5 as shown in FIG. It is located rearward from the terminal end 13' and retreated into the hollow part of the mantle tube part 3, and when the cutting blade shaft 2 rotates, the cutting blade part 4 is moved by the forward thrust accompanying the rotation as shown in FIG. The scion twig 18 moves forward to the inside of the receiving blade 16 as shown in FIG.
It is configured to constitute a cutting mechanism that pinches and cuts the branches of the blade.

In the processing apparatus of the present invention having the above configuration, the electric motor 4 is provided with a foot switch (not shown), and the first
As shown in FIG. When the cutting blade 4 is rotated, the cutting blade 4 moves forward as shown in FIG. 4, and unnecessary branches and leaves are sequentially cut off to form the desired scion 19.

According to the scion processing device for cuttings of the present invention as described above, the cutting blade shaft 2 has a hollow cylindrical shape and has a cutting blade portion 4 at the head.
An outer tube part 3 having a lug-shaped guide part 13 is fixed to the tip of the blade, and when the cutting blade shaft 2 is stopped, the cutting blade part 4 is retracted from the guide part 13, and the rotation of the cutting blade shaft 2 is prevented. At the same time, the cutting blade part 4 moves forward and forms a cutting blade mechanism together with the receiving blade 16 inside the guide part 13 to cut branches, etc., so that the whole part is densely covered with branches and leaves. When inserting the bushy scion twig 18 into the cutting blade shaft 2, the tuft-shaped guide portion 13 can fully perform the guiding action, so that the branches and leaves form the sharp cutting blade. It has a unique effect that allows the scion twig 18 to be inserted very smoothly and easily without any obstacles such as getting caught in the part 4.

After the insertion operation, when the cutting blade shaft 2 is rotated, unnecessary branches and leaves are immediately cut off, and the scion 19 for cuttings can be formed extremely easily.

"Effects of the Invention" As described above, the scion processing device of the present invention has an excellent effect of efficiently processing cutting scions 19 for planting and afforestation with simple operations. Moreover, since the structure is simple, it can be molded to be lightweight and compact, making it convenient to transport and move, and has the practical advantage of being easily placed and used at a required location.
