Description

[Detailed explanation of the invention] (Technical field of the invention) This invention is aimed at cultivating mushrooms such as shiitake,
In a mushroom seed driving machine that uses a driving force to drive a seed seed inoculated with mushroom fungi into logs, a set claw for holding the seed seed provided at the tip of the driving nose is used. Regarding structure.

(Technical background of the invention and its problems) In the past, the work of driving seed pieces was mostly done by hand, but there was no hope of improving productivity and there was a shortage of manpower, so mechanization and automation of this work was required. However, in recent years, development has gradually progressed, and automatic driving machines that are practically satisfactory to some extent have become available.

In such a driving machine, the seed pieces are sequentially supplied to the nose of the punching section and are driven by impact using a power-driven driver member, etc., but in the preparation state for driving, the seed pieces are not driven at the setting claw. Hold for a moment. Then, the protrusion of the seed piece, which is partially exposed to the outside in the held state, is applied to an inoculation hole previously provided in the log and driven.

Therefore, since the protruding portion of the seeding piece serves as a pilot, it is desirable that the amount of protrusion of the seeding piece is always constant in order to perform speedy work without making mistakes.

However, due to the nature of the seed piece, highly sticky fungus forms and adheres to the surrounding area, and this also adheres to the punching path and around the setting claw, obstructing the smooth feeding of the seed piece. , there is a problem that a stable protrusion amount cannot be obtained. Furthermore, with repeated use, debris such as wood chips accumulates on the tips of the setting claws, further deteriorating the performance of holding the seed pieces and posing a major obstacle to the work of driving the seed pieces.

Therefore, it is necessary to frequently clean the inner portion of the set claw to remove any deposits that may have adhered thereto.

Also, if the seed piece is accidentally introduced in the wrong direction and jams inside the nose, it is necessary to remove it.

However, in the case of conventional setting claws, it is impossible to open the claws sufficiently wide due to their structure, and since the setting claws are always urged by a spring in the direction of holding the seed piece, this spring It was extremely difficult to push the claws open and clean the inside.

(Purpose of the invention) The present invention was conceived in view of the above circumstances, and its purpose is to release the spring biasing force of at least one of the setting claws as needed, and to widely open the inner surface of the setting claw. To provide a structure of a setting claw in a mushroom seeding machine which is simple in structure and operation.

(Summary of the invention) In order to achieve the above object, the present invention basically consists of a mushroom seeding machine with a pair of setting claws for holding seeds at the tip of a seeding machine nose. In a setting machine, one end of a leaf spring member is rotatably attached to at least one set claw with the rotation axis of the set claw and the rotation axis of the leaf spring member perpendicular to each other, and the leaf spring member is a first position in which the other end resiliently abuts against the main body of the mushroom seed driving machine to bias the one setting claw in a direction to hold the seed piece; and the leaf spring member. A mushroom seed holder characterized by a structure in which the other end part is separated from the main body part and can be rotated between a second position that allows free rotation of one set claw. This paper proposes the structure of the set pawl in the machine.

In the above structure of the present invention, when the leaf spring member attached to one set pawl is placed in the first position, the spring biasing force of the leaf spring member itself acts on the one set pawl. It works together with the pawl to hold the seed piece, and on the other hand, when it is rotated to the second position, the biasing force applied to the one set pawl is released, and the set pawl can be opened freely and at a large angle. This allows for easy and sufficient maintenance such as internal cleaning.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

In the mushroom seed-driving machine shown in Fig. 1, 1 is the main body of the machine, 2 is a nose forming a part of the main body and has a punching passage 3 formed inside, and 4 is the punching machine. A driver member 5 reciprocates in the passage 3, and 5 is a power drive mechanism in the main body 1, which is constituted by a piston/cylinder operated by pneumatic pressure or electromagnetic force, for example, so as to apply an impact driving force to the driver member 4. , 6 is a trigger lever for actuating the power drive mechanism 5, and 7 is a latching portion 7a for normally latching the trigger lever 6 in the non-operating position shown. A safety device 11 is mounted so as to be slidable in the vertical direction through a hole 9 and biased in one direction by a spring 10, and a safety device 11 is pivotally supported by the nose 2 and biased by a spring 12 to an engagement position with a seed piece 13. The check lever 14 is constructed integrally with the nose 2 and forms a piece feed passage 15 communicating with the punching passage 3 inside, and is connected to insert a piece supply pipe 17 connected to a seed piece supply source 16. Department.

The seed pieces 13 are supplied by air pressure from the seed piece supply source 16 to the piece feeding passage 15 via the piping 17, and are set with a set pawl 18 provided at the tip of the nose 2, with a truncated conical head as shown in the figure. It is held at the driving preparation position in which the part protrudes by a predetermined amount.

In this position, the check lever 14 is connected to the seed piece 13.
The seed piece 13 is held in a position where it is not inserted into the interior by engaging with the inner end surface of the seed piece 13.

During the non-driving operation, the safety device 7 leaves its tip 7b in a state that protrudes further than the protruding seed piece 13, but when the driving operation starts, the seed piece 13 is inserted into the inoculation hole 20 previously drilled in the log 19. When brought close, the tip 7b engages with the log 19 and springs 1.
0 and is pushed in the direction of the arrow. Therefore, the trigger lever 6 comes off from the hook 7a and becomes automatically operable.

In the driving operation, when the protruding part of the seed piece 13 is used as a pilot and is applied to the target inoculation hole 20 and the trigger lever 6 is operated, the driver member 4 is driven by the power drive mechanism 5 in the direction of the arrow as shown by the chain line. An impact force is applied to the seed piece 13 and the seed piece 13 is driven into the inoculation hole 20 from the set claw portion 18.

After one driving is completed, the driver member 4
returns, and the next seed piece is supplied from the piece feeding passage 15 to the setting pawl portion 18. At this time, the check lever 11 is retracted from the passage against the spring 12, and is moved to the preparation position shown in the figure as described above. It is positioned as

Next, the structure of the setting claw of the present invention will be explained with reference to FIGS. 2 and 3.

In FIG. 2, the set pawl portion 18 has a pair of set pawls 2 facing each other across the punching passage 3.
1 and 22 are rotatably supported on the nose 2 by a spindle 23, and the base end or one end of one of the set claws 21 is rotatably attached to the set claw 21 by a spindle 24, and is freely attached to the set claw 21. A plate spring member 25 having an operating portion formed at one end or the other end 25a forms a unit with the set pawl 21.

When the leaf spring member 25 is in the first position where it is straight in the same direction as the set claw 21 as shown by the solid line in FIGS. The other end 25a elastically abuts against the outer circumferential surface of the nose 2, which forms a part, due to the spring action of the leaf spring member, and the reaction force causes the setting claw 21 to move in the direction in which the seed piece 13 is held, that is, in the direction in which the seed piece 13 is held. In FIG. 2, it is urged clockwise around the support shaft 23 and is held at the solid line position (holding position) where the shoulder 21a engages with the end of the nose 2.

On the other hand, if the leaf spring member 25 is rotated in the lateral direction shown by the arrow with the operating portion around the support shaft 24 to the second position shown by the chain line in FIG.
The other end 25a is disengaged from the nose 2, and the spring biasing force of the leaf spring member 25 is released.

Therefore, since no biasing force is applied to the set claw 21, it can be opened widely in the direction of the arrow from the shown holding position to the open position shown by the chain line.

In the case of the above configuration, the set claw 21 shown in FIG.
The rotation axis XX of the support shaft 23 and the plate spring member 25
Since the rotation axes Y-Y of the support shafts 24 are perpendicular to each other, the leaf spring member 25
In this position, even if a force is applied to the set claw 21 in the opening direction during a driving operation, no force is generated in the leaf spring member 25 to rotate it. Therefore, the set claw 25 can be held securely.

The other set claws 22 have the same structure as the conventional one, and are constantly pressed and held at the illustrated holding position by a coil spring 26 disposed between them and the nose 2. and,
The biasing forces exerted on the setting claws 21 and 22 of the coil spring 26 and the plate spring member 25 are set to be equal, and the seed piece 13 is held in a well-balanced manner by both setting claws.

When removing wood chips etc. accumulated inside the setting claws 21 and 22, cleaning the inside, or removing seed pieces jammed inside, the leaf spring member 25 is rotated to the second position as described above. By doing so, the spring bias against one of the setting claws 21 is released and the opening can be easily opened over a wide angular range, making maintenance work extremely easy.

In the conventional case, the setting claw could only be opened at an angle of about 10° at most, but in the case of the present invention, it is possible to open the setting claw to an angle of nearly 45° by opening only one setting claw.

Therefore, as in the embodiment, one set claw 21
Although it is sufficient to provide the leaf spring member 25 only in the second setting claw, the other setting claw may also have the same structure so that it can be opened more widely.

(Effects of the invention) As described above, according to the invention, the setting claw can be opened freely and widely by a simple rotation operation of the leaf spring member, so it is possible to clean the inside and remove jammed seed pieces. Maintenance work such as this can be done easily and thoroughly, and since the leaf spring member has both the function of a biasing spring for the set pawl and the function of an operating lever, the structure is simple and easy to operate.
It has various effects.
