Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to shiitake mushroom logs (also simply referred to as logs).
The present invention relates to a perforation device for planting seed fungi (also referred to as Shiitake fungi).

(Prior Art and Problems to be Solved by the Invention) Shiitake fungi (inoculum) is generally produced by planting Shiitake fungi on a cylindrical piece of wood called "komobyo".
A type of ``Koma fungus'' called ``gypsum fungus,'' which is made by mixing and hardening plaster and sawdust and then planting Shiitake fungi there, or by planting Shiitake fungi into a wood powder called ``Oga fungus.'' Depending on the form of things, etc.
They are planted in planting holes drilled into logs.

[Prior Art 1] Conventionally, the present applicant has fixed the log on which the above-mentioned Koma fungi are to be planted, and while it is fixed, drills a hole for planting (planting hole) with a power drill. , an inoculation method that automatically performs a series of operations (Patent No. 863374), in which a power drill is extracted from this hole, and a mold is supplied above the hole and driven into the hole based on information. ), and this specification discloses a specific apparatus for carrying out this method.

This device will be briefly explained in accordance with the operating order based on FIG. 2. The push lever (not shown) attached to the guide frame 2 (the push lever
6), the pressing frame 1 that fixes the log 11 from above descends together with the guide frame 2, and the log 11 is fixed between the pressing frame 1 and the mounting table (not shown). Then, the guide frame 2, which is loaded with a spring (delivered with elasticity) on the push frame 1 via the suspension rod 9, resists the elastic force of the spring. When pushed down,
A power drill awl 1 is integrally attached to the guide frame 2.
5 also descends to drill a planting hole in the fixed log, and then the power awl equipped with the awl 15 and the guide frame 2 ascend. While the guide frame 2 is descending, the piece bacteria 51 supplied to the front of the piece bacteria supply frame 50 are
The bacteria are supplied to the planting hole position by a mold supply frame 50 that moves forward as the guide frame 2 rises,
The mold fungus 51 is driven into the planted hole drilled above using a driving hammer 52 from above.

However, in the case of the above-mentioned method or device, for each position where planting is to be done, the guide frame to which the power awl is integrally attached is placed against the push frame in which the guide frame is loaded. You have to lower it one by one by hand.

This series of operations was extremely hard work for the shiitake mushroom cultivators, who inoculated thousands of mushrooms per day.

[Prior Art 2] There is also a drilling device devised by the applicant for the purpose of reducing labor (utility model registration number).
No. 1352343). That is, as shown in FIG. 3, this drilling device is designed by the applicant to use a general-purpose drilling machine 70 to automatically drill a hole in a log for inoculating seed fungi. A pulley 73 is disposed on a lowering lever shaft 72 that lowers a main shaft (rotating shaft) 71 of a general-purpose drilling machine 70.
was intermittently rotated by a deceleration motor 76 via two link plates (sliding rod 74, swing lever 75) to automatically drill holes.

However, in the case of this device, as long as the deceleration motor is rotating, the lifting and lowering operations (drilling operations) are repeated continuously. This method has the disadvantage that it is difficult to drill holes in the log at desired intervals even by an experienced person because the thin, curved log must be moved.

Additionally, as mentioned above, some logs are generally curved, and in the case of curved logs, for example, when drilling in an upwardly curved area, a drill is used to press the log downwards. There was a problem in that the log was bent downward, making it difficult to perform the drilling work smoothly. In particular, it was even impossible to do so in the case of thin logs.

Furthermore, since it is constructed using a general-purpose drilling machine, it is extremely heavy and difficult to transport to multiple locations (in the mountains) where shiitake mushroom logs are located, and in this respect, it is also inconsistent with the current state of shiitake mushroom cultivation. It was hot.

[Prior art 3] Furthermore, a completely automated drilling device (Tokuko Showa)
50-15699), but in this case as well, the force that presses the power drill downward is directly applied to the log, as in the case of Utility Model Registration No. 1352343 shown in Figure 3 above. As a result, if the log is thin, it will be pushed downward by the drill and bend, making the drilling operation very difficult or completely impossible. Furthermore, it was even heavier than the above-mentioned one, and it was completely impossible to move it around multiple sites (in the mountains) where shiitake mushroom logs were located.

The present invention was made in view of the above-mentioned current situation, and an object of the present invention is to provide a semi-automatic shiitake mushroom log drilling device that reduces labor, has good performance, and is easy to transport.

(Means for Solving the Problems) In the shiitake mushroom log drilling device according to the present invention, when a drilling start operation is performed, the power drill located above is automatically moved to the side of the log placed on the lower machine stand. In a shiitake mushroom log drilling device that descends and ascends to make a hole, a pressing frame for pressing the log from above is mounted on the machine and is swung vertically by a horizontally disposed pivot shaft. A push lever is attached to the operation side of the push frame to allow the push frame to move freely, and a push lever for pushing against the raw wood is attached to the operating side of the push frame. A guide frame is mounted above the pressing frame so as to be movable vertically toward and away from each other, and the power drill for drilling is integrally disposed on the guide frame, and between the guide frame and the pressing frame. In addition, an approach/separation operation means such as a crank mechanism is installed to move the guide frame up and down with respect to the pressing frame using power during the drilling start operation, and during the drilling operation, power is applied to the pressing frame. The guide frame equipped with the awl moves up and down, and the force that presses the power awl downward acts on the pressing frame and does not directly act on the raw wood.

(Function) Therefore, in the shiitake mushroom log drilling device configured as described above, when the pressing lever is used to bring the pressing frame into contact with the log placed on the machine base and the drilling operation is performed,
The guide frame is lowered by the push lever with respect to the push frame held at a predetermined position by the operator, and a power drill integrally disposed on the guide frame drills a hole in the log. Therefore, the force that presses the power drill downward acts on the pressing frame, and the force that presses the power drill downward does not directly act on the log. That is, since the only force acting on the raw wood is the force that the operator presses with the pressing lever, it is possible to smoothly drill holes in any thin raw wood by arbitrarily adjusting it depending on the thickness of the raw wood.

In addition, since the drilling start position is set by touching the push lever against the log, the drilling start position can be set freely and easily, even when the log is curved or has a different thickness. It is possible to drill holes easily and smoothly.

Furthermore, simply by pressing the pressing frame against the raw wood using the pressing lever and operating the approaching/separating actuating means to start drilling, the approaching/separating actuating means such as a crank mechanism is actuated by the power and the above-mentioned pushing/separating actuating means is automatically activated. The guide frame performs a series of lowering and raising movements relative to the contact frame. Therefore, if the same fungus supply mechanism and driving mechanism as in the above-mentioned "[Prior Art 1]" are provided, the drilling and inoculum planting work can be semi-automatically performed at any part of the log.

Even though this drilling device is semi-automated, it has a very simple configuration, including a configuration for semi-automation, so it can be extremely lightweight and can be easily transported even in the mountains. It can be done.

(Example) The present invention will be described below based on an example with reference to the drawings.

FIG. 1 is a side view showing the overall general configuration of a shiitake mushroom log drilling device according to the present invention.

In the figure, 1 is a push frame, and 2 is a guide frame. The push frame 1 and the guide frame 2 are connected by a vertical slide shaft 9 so that they can move toward and away from each other. Also,
Although not shown, the slide shaft 9 is equipped with a coil spring, and the guide frame 2 is elastically loaded against the pressing frame 1.

Further, the press frame 1 and the guide frame 2, which are connected to each other so as to be linearly movable via the slide shaft 9 at the front (front side; left end in the figure), ) and the upper end of the link plate 4 which is pin-coupled to the center part of the guide frame 2 and the shaft 8.
The rear end of the link plate 7, which is pin-coupled at , are connected so as to be movable toward each other and away from each other.

The pressing frame 1 and the guide frame 2 are
In this embodiment, a crank mechanism is provided as the separating operation means. That is, a disc body 30 is rotatably disposed on the extension portion 3 of the pressing frame 1, and this disc body 3
A crank plate 5 is integrally attached to the crank plate 5, and one end of the crank rod 6 is pin-coupled to the outer end of the crank plate 5, and the other end of the crank rod 6 is pin-coupled to the link plate 7. When the plate body 30 rotates, the pressing frame 1 and the guide frame 2
are configured to move toward and away from each other.

The disc body 30 is rotatably connected to a deceleration motor 14, which is also disposed on the extension portion 3 of the press frame 1, by a belt 14'.

A tension pulley 13 is in contact with the belt 14', and the tension pulley 13 is rotatable toward the free end of a support rod 31 whose one end is pivotally supported by the extension 3 of the press frame 1. By rotating this support rod 31, the belt 14'
It is structured in such a way that it is possible to relieve and relieve tension.
Further, a branch rod 31' is extended from the support rod 31,
One end of a cable, the other end of which is connected to a foot-operated operating pedal 12, is connected to this branch rod 31', so that tensioning and relaxing of the belt 14' can be controlled remotely.

The pressing frame 1 can swing freely in the X direction in the figure around a horizontally arranged pivot shaft 18, and can also rotate on a horizontal plane around a vertically arranged rotating support 19. It is attached to machine base B so that the Therefore, the pressing frame 1 can freely swing in three dimensions on the machine base B.

In addition, as shown in FIG.
It is integrally attached so that it can be drilled into the
A log mounting table 33 on which logs 11 are placed and is movable in the longitudinal direction by means of wheels 32 is disposed on the machine stand B located below.

Furthermore, the push frame 1 has a push lever 1 facing toward the operator (the left side in FIG. 1).
0 is extended.

By the way, in this device, the electric drill 34 etc. are placed in front of the pivot shaft 18, and the deceleration motor 14 etc. are mounted in front of the pivot shaft 18 so that the weight can be balanced front and rear (left and right in FIG. 1) around the pivot shaft 18. A spring 17 is disposed at the rear and acts in a direction to pull the press frame 1 and the machine base B at the rear of the press frame 1.
is installed.

Although omitted in FIG. 1, the mechanism for drilling the planting hole, supplying the mold fungus, and driving the mold fungus is similar to the structure shown in FIG. Things are equipped.

Therefore, the Shiitake mushroom log drilling device having the above-mentioned configuration operates as follows when drilling a hole for planting the seed fungus.

That is, first, before starting the work, place the log 11 on the mounting table 33, hold the pressing lever 10, and lower the pressing frame 1 so that the awl 15 is positioned above the area where the mold is to be planted. is swung up and down or left and right about the pivot shaft 18 or rotation support 19, and then the push lever 10 is pushed down to bring the push frame 1 into contact with the log 11. At this time, the pressing frame 1 can freely swing in three dimensions as described above, and the log mounting table 33 on which the log 11 is placed can move in a direction perpendicular to the longitudinal direction of the pressing frame 1. Therefore, even if the log is curved in plan or laterally, the awl 15 can be easily positioned at a predetermined position on the log.

When the drill bit 15 is set above the drilling position, the power of the device is turned on and the deceleration motor 14 and the electric drill 34 (the drill bit 15) are rotated.

In this state, when the proximity/separation actuating means performs a drilling start operation (work start operation), that is, when the foot-operated operation pedal 12 is stepped on, the cable connected to this pedal 12 is pulled and the branch is opened. The support rod 31 is rotated toward the operator (counterclockwise in FIG. 1) via the rod 31', and as a result, the tension pulley 13 tensions the relaxed belt 14'.

Therefore, the rotation of the deceleration motor 14 is transmitted to the disc body 30 via the belt 14', and the rotating body 30 rotates.

Due to this rotation of the disc body 30, the end of the crank rod 6 attached to the disc body 30 rotates around the rotation center of the disc body 30, and as a result, the other end of the crank rod 6 is rotated about the rotation center of the disc body 30. The shaft 8 side of the link plate 7 connected to the end moves up and down, and the guide frame 2
is raised and lowered with respect to the press frame 1 along the slide shaft 9.

If this lifting and lowering is automatically performed by the above operation, the conventional configuration described in "[Prior Art 1]" will automatically drill the planting hole, supply the bacteria,
You can perform a series of operations for inserting the pieces. Furthermore, it goes without saying that seed bacteria other than Koma fungi can also be applied in the same manner as for Koma fungi, if there is a device for automatically supplying and planting the seed fungi.

Further, in the above embodiment, a five-bar link mechanism was interposed between the push frame 1 and the guide frame 2 as the approach/separation actuating means, but instead of this, although not shown, , as the above approach/separation operation means,
A pressure cylinder or a pneumatic cylinder may be interposed between the push frame and the guide frame, and these cylinders may be controlled electrically or the like to move in conjunction with the lowering of the push frame. good.

When configured as in the above embodiment, the guide frame 2
This makes it easier to drill even thin or curved logs, compared to the case where the press handle 16 attached to the machine is pressed down each time to drill holes, and compared to the drilling device using a drilling machine shown in Fig. 3. be able to.

That is, in the case of the device according to the present invention, during drilling, the guide frame 2 is lowered relative to the pressing frame 1, and as described above, the guide frame 2 moves back and forth in terms of weight around the pivot shaft 18 (see Fig. 1). Because it has a well-balanced structure (left and right), the push frame 1
The force that presses the awl 15 downward or the weight of each component above the pressing frame 1 does not directly act on the log below, and only the minimum pressing force necessary for fixing the log and drilling the hole is applied. Doesn't work.

Therefore, even if the log is thin or curved, it can be operated without any excessive bending force being applied to the log, making it possible to drill holes easily and smoothly.

In addition, as mentioned above, since the structure is balanced in the front and back with the pivot shaft 18 in between, the operator can easily press the push lever 10 with a light force on the pivot shaft 18 or the rotation support 19. It becomes possible to swing up, down, left and right around the awl 15, which reduces the labor required for positioning the awl 15 and during drilling work, making the drilling work very easy. Therefore, even a weak elderly person or woman can easily operate the device.

In addition, in the case of the drilling device according to the above embodiment, most of the frame etc. can be formed from pipes, etc. compared to the conventional drilling device using a drilling machine, so the overall weight can be made extremely lightweight. I can do it.

(Effects of the Invention) The present device, which is configured and operates as described above, simply positions the part of the log in which the planting hole is to be drilled, pushes down the pressing frame, and starts the operation of the approach/separation actuating means. This not only makes the work much easier, but also allows the entire work to be done semi-automatically, which saves work compared to conventional manual equipment. Efficiency improves dramatically. For example, according to the applicant's experiments and comparisons, in the case of the above-mentioned "[Prior Art 1]" device, about 5,000 to 6,000 pieces were produced in a day, but in the case of the present device, Approximately in one day
Approximately 10,000 to 12,000 plants can be planted.

Furthermore, it is possible to work smoothly on crooked or thin logs, which is impossible with the automatic drilling machines described in "[Prior Art 2]" or "[Prior Art 3]" similar to the present invention. Therefore, the drilling device according to the present invention works very effectively in the actual drilling work of shiitake mushroom logs, which are actually quite often curved or thin. Furthermore, since the punching device according to the present invention is constructed from members that are structurally simple and can be made lightweight, it can be significantly lighter than conventional automatic punching devices, and therefore,
It can be easily transported to the mountains where shiitake mushroom logs are located. As a result, the above-described drilling work can be carried out efficiently no matter where and what shape of log is used.
