BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shiitake mushroom raw wood punching machine for punching a large number of inoculum holes in a shiitake mushroom cultivation log.

[0002]

Conventionally, such a log for shiitake cultivation has a diameter of 10
About 1 cm long with a length of about 1 m is used. Quark, Japanese oak, and kunugi are the most suitable as such logs, and these natural trees are usually curved in various ways, and many holes are drilled at the same time. It had the drawback that it could not.

Further, the raw wood in which the inoculum is planted is called a bark, and such a bark takes about one year to spread the hyphae.
I fell asleep in the forest and shiitake mushrooms have been occurring for 1 year,
In order to spread the hyphae in this way, it is desired to perforate the hyphae in a predetermined depth and in the central direction.

DISCLOSURE OF THE INVENTION According to the present invention, a large number of holes are punched in a log, and a curved log can be punched at the same time. Further, a shiitake mushroom is drilled at a predetermined depth and in the center direction of the log. The purpose is to provide a punching machine for raw wood.

[0005]

DISCLOSURE OF THE INVENTION The present invention is based on the above-mentioned prior art, and it is impossible to pierce a large number of holes at the same time, a curved natural tree cannot be pierced, and a central tree is pierced at the same depth. in view of the challenges that can not be, transverse to the frame
A plurality of lifting shafts are vertically movable in the vertical direction , and a drill body holder is mounted on the lower end of the lifting shaft so that the posture can be freely changed by swinging back and forth around a pin as a fulcrum. In addition to being movable, a drive unit and a control board are fixed, a depth setting tool and a drill blade are attached to the drive section, and a slide shaft is attached to the control board so that the slide shaft can move up and down. Is the diameter of the log
By attaching a contact plate formed in an inverted V shape to the above , a large number of holes are simultaneously formed in a curved natural tree in a predetermined depth and in the direction of the center to solve the above problems. Is.

[0006]

According to the present invention, when the driving part of the drill is operated and the rocking lever is lowered, the rocking shaft of the lifting device rocks and descends via the rocking arm around the bearing and the rotary shaft. Then, from the state in which the drill body holder was held by the abutment plate of the swing shaft via the lift rod, the lift shaft of the drill body holder freely descends with respect to the guide as the swing shaft descends. Is lowered, the reverse V-shaped contact plate at the lower end of the drill comes into contact with the upper surface of the log, and the drill blade changes its posture toward the center of the log so that the contact plate entirely contacts the upper surface of the log. Simultaneously with the action, the spring is compressed by the weight of the drill, the tip of the drill blade comes into contact with the upper peripheral surface of the log, and the drill blade progresses toward the center of the log to make a hole, and the depth setting tool is the top of the log. Drill until it touches the peripheral surface and drill to the set depth. Than it is.

[Effect of the Invention] In short, the present invention is applied to the frame 2.
A plurality of elevating shafts 10 are mounted in the horizontal direction so as to be vertically movable, and a drill body holder 12 is mounted at the lower end of the elevating shaft 10 so that the posture can be freely changed. The drill body holder 12 is vertically movable by an elevating device 7. At the same time, the drive unit 15 and the control board 16 are fixed, the depth setting tool 17 and the drill blade tool 19 are mounted on the drive section 15, and the slide shafts 20 and 20a are mounted on the control board 16 so as to be vertically movable. Slide shaft 2
Since the abutment plate 24 is attached to the lower end of 0, 20a, a large number of holes for inoculum can be drilled at the same time, and the drills 4, 4a ... 4a ... Can be punched in the direction of the center of the raw wood M so that they coincide with each other, and at the same time, the set depth H set by the depth setting tool 17 can be punched. Further, since the lower end of the elevating shaft 10 and the drill body holder 12 are swingable in the front-rear direction via the pin 11, the posture change of the drills 4, 4 a ... It is possible to swing the drill body holder 12 in the front-rear direction by a simple pivoting mechanism with the fulcrum 11 as a fulcrum, so that the abutment plate 24 side of the drill body holder 12 in the horizontal direction by the lowering operation of the swing lever 27. The movement of the drill 11 can be performed by swinging the fulcrum of the pin 11, and the posture of the drill 4, 4a ... Can be smoothly changed without forcibly changing the movement direction. In addition, the contact plate 24 has a diameter of the raw wood M.
Since it has an inverted V shape in the direction, the log M is curved
Also, after a part of the contact plate 24 contacts the log M, the entire contact
And the contact state, the drill body holder
The -12 can be reliably rocked back and forth.

In the lifting device 7, the swing lever 2
7, the swinging arms 26, 26a are interlocked, and the swinging shaft 29 is fixed to the swinging arms 26, 26a, while the lift bar 13 is projectingly fixed to the drill body holder 12. Since the rocking shaft 29 is brought into contact with the lower part from below, a large number of drills 4, 4a are attached to the curved log M.
... it is possible to perform the optimum drilling operation and lowering operation with its own its own weight, drilling by lowering operation of MataYurado lever 27
When lowering the body holder 12, it moves upwards by its own weight.
There is no pressing force from the drill, and the drill uses the pin 11 as a fulcrum.
Smoothly change the swinging posture of the body holder 12.
Therefore, the posture can be changed smoothly with a simple mechanism.
Therefore, the occurrence of failure can be eliminated.

Further, since the mounting table 8 for the raw wood M mounted on the frame 2 can be set in the vertical height, the mounting base 8 is moved up and down so that the upper peripheral surface height of the raw wood M is changed to the drills 4, 4a. On the other hand, the height can be appropriately set, and it is possible to cope with different diameters of the raw wood M which is a natural wood, which is a great practical effect.
