Abstract

PROBLEM TO BE SOLVED: To provide a machine for planting a mushroom spawn block capable of carrying out operations from boring on a log for mushroom to driving of spawn block automatically and efficiently without a burden to an operator. SOLUTION: An auger 7 of a drill is connected to a spindle 4 attached to a main body frame 1 in such a way that the auger can be relatively rotated but can be freely slid in the axial direction and is moved backward and forward by an air cylinder 8. When the auger 7 bores a log for mushroom and is moved backward, a spawn block inserting element 9 is advanced in a traveling path of the auger 7. The spawn block retained in a guide hole 9a of the inserting element 9 is driven into a hole bored in the log for mushroom by a hammer 12 operating afterward. Consequently an operator only brings a spike plate 1b into contact with the log for mushroom and operates a switch.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mushroom seed piece planting machine for automatically performing a process of making a hole in a log for cultivating a mushroom and planting a seed piece having a seed fungus in the hole.

[0002]

2. Description of the Related Art Artificial cultivation of shiitake mushrooms is performed by drilling holes in a log of beech family (firewood) cut to an appropriate length, planting seed pieces in the holes, and placing the seeds in a place suitable for cultivation (appropriate. It is done in a way that waits for shiitake to grow.

Recently, seed pieces have been planted by transporting cut logs to a factory from a mountain, performing pretreatment from drilling to planting, and returning the treated logs to a cultivation field. However, this method is difficult to transport logs.

Accordingly, the present applicant has developed and proposed a seed piece planting machine capable of performing pretreatment efficiently at a local site (a cultivation site such as in the mountains). For planting in the field, usually a hole is drilled in the log with an electric drill, and then a seed piece is hammered with a hammer in the manner of nailing.
This method is inefficient, and the labor burden on the operator is large. In order to eliminate this problem, the above planting machine adds a seed piece feeder and a seed piece driving hammer to a portable electric drill, so that the seed piece is automatically supplied and driven after drilling holes in the log. To be made.

[0005]

The planting machine described above is
A spring-biased backing plate is provided at the tip of the electric drill, and the backing plate is applied to the log when drilling, and the spring is compressed to feed the drill. After drilling, it is necessary to return the drill to the origin with the force of the spring, and to confirm the return to the origin with a limit switch, etc., and then to activate the seed piece feeder and hammer. However, since this planter compresses the spring with the force of the operator, the operator is easily tired. The reaction force of the spring is not so large, but the number of perforations per log is generally as large as about 20 to 25, so fatigue is accumulated when drilling is repeated against the reaction force of the spring,
Work efficiency decreases.

[0006] Many people who are engaged in cultivation of shiitake mushrooms and the like are elderly people, and work is difficult on machines that are easily fatigued. Therefore,
There is a need for a lighter planter that can be easily operated without using force.

An object of the present invention is to meet such a demand.

[0008]

In order to solve the above-mentioned problems, in the present invention, a drill bit for making a hole in a log is connected to a spindle that is rotated by a motor so that the drill bit cannot rotate relative to the spindle and is movable relative to the axial direction. Then, a push-pull means for moving the cone forward and backward is provided. Specifically, the seed piece planter was configured as follows. That is, a drill connected to a spindle rotated by a motor so that the drill cannot rotate relative to each other, and slidably in the axial direction, a pushing and pulling means for moving the drill drill forward and backward, a seed piece introduction pipe for guiding a seed piece from a supply unit, and a pipe for the pipe Seed piece feeder that receives the seed piece supplied from the introduction pipe in the guide hole while waiting at the exit, position switching means of the feeder that displaces this seed piece feeder from the standby point on the traveling path of the cone, retreating A hammer that enters from the evacuation point and pushes out the seed piece held by the seed piece feeder through the guide hole between the drilled cone and the seed piece feeder moved in front thereof, the driving means of the hammer, and the above Has a body frame that can be held by hand to attach each element of
The drill is used to make a hole in the log, and after the retraction of the drill, the seed piece transmitter moves in front of the drill, and then the hammer operates to drive the seed piece held by the transmitter into the hole drilled in the log. I made it.

In this planting machine, the drill motor can be incorporated in the main body frame. However, when the output shaft of the motor and the spindle mounted on the main body frame are connected independently by a flexible shaft, the motor is further independent. Can be reduced in size and weight.

It is preferable to provide a seed piece storage hopper having a seed piece sending mechanism. The seed piece storage hopper is
It may be attached to the main body frame, or may be independent from the main body frame, placed on the ground, and pneumatically fed the seed pieces from there through the seed piece introduction pipe.

In some cases, it is preferable to form the seed piece introducing pipe with a coil spring having a small coiling pitch.

[0012]

According to the present invention, since the drill bit is advanced and retracted by the push-pull means, there is no need to manually push the drill, and a series of operations can be performed without using force.

[0013] In addition, an independent drill motor can be further reduced in size and weight, and can be more easily handled.

Further, a seed piece storage hopper having a seed piece sending mechanism is added, so that seed pieces can be supplied efficiently. It is preferable to increase the capacity of the hopper to reduce the number of seed piece replenishments in continuous work. However, if a large hopper is attached to the main body frame 1, the work may be hindered and work may be difficult. Recommends that the hopper be placed on the ground independently.

In addition, when the planting machine is continuously used, fungi and debris of the seed piece falling from the piece may stay inside the seed piece introduction pipe, and the pipe may be clogged. The introduction pipe formed by the coil spring can sift foreign substances that are likely to accumulate inside to the outside, and do not cause clogging of the pipe. Further, since the coil spring bends freely, even if bending and stretching are repeated, fatigue and breakage of the pipe do not occur.

When the seed pieces are pneumatically fed, a seed piece introducing pipe which does not hinder the pneumatic feeding is required.

[0017]

1 to 6 show an embodiment of a seed piece planter according to the present invention.

FIG. 1 shows a grip 1a and a spike plate 1;
b is a main body frame. A drill operation switch 2 and a work start switch 3 are provided on a grip portion of the main body frame 1.

Reference numeral 4 denotes a spindle of the drill attached to the main body frame 1. The spindle 4 is connected via a flexible shaft 5 to a motor (not shown) independent of the main body frame 1. The motor may be an air motor, but an electric motor that is easy to control is suitable.

A vertically long keyway 4 is provided on the outer periphery of the spindle 4.
a, and a slide shaft 6 is connected to the tip of the spindle 4 via a key 6a slidably engaged with the key groove 4a so as to be relatively non-rotatable and slidable in the axial direction.
A drill cone 7 is attached to the tip of the slide shaft 6.

An air cylinder 8 is mounted on the main body frame 1.
The output rod 8a of the cylinder is hollow, and a slide shaft 6 is arranged at the center of the hole of the rod. The slide shaft 6 is supported by the output rod 8a so as to be rotatable and not to move relatively in the axial direction. Accordingly, the cone 7 being rotated by the air cylinder 8 can be moved forward and backward. The pushing and pulling of the cone 7 can be performed by a ball screw or the like. However, a ball screw with a motor for rotational driving causes an increase in the size and weight of the planting machine.

Reference numeral 9 denotes a seed piece feeder provided at the end of the main body frame 1. The seed piece feeder 9 is made to stand by at an outlet of a seed piece introduction pipe 10 fixed to the main body frame 1.

Reference numeral 11 in FIG. 2 denotes a position switching means for seed piece transfer. The position switching means 11 comprises an L-shaped arm 11a swingably attached to the main body frame 1 using a horizontal support shaft, and an air cylinder 11b for swinging the arm 11a. The arm 11a is connected to the air cylinder 11b. 2, the arm 1 is rotated clockwise.
1a, the pin 11c engaged with the slit at the front end is pushed down, and the seed piece feeder 9 having the pin 11c attached thereto is shown in FIGS.
Move to the position shown in.

The seed piece feeder 9 is provided with a guide hole 9a (see FIG. 4) for receiving a seed piece from the seed piece introduction pipe 10.
When the seed piece feeder 9 is at the origin (the position of the solid line in FIG. 1 or 2), the guide hole 9a is connected to the outlet of the seed piece introduction pipe 10, and the seed piece feeder 9 is moved to the position shown in FIGS. When it moves to the position, it comes to the center of the traveling path of the cone 7. When the seed piece feeder 9 is at the origin, the spike plate 1b closes the exit of the guide hole 9a, so that the seed piece supplied from the seed piece introduction pipe 10 is
It enters the guide hole 9a and is held in the hole 9a.

In FIG. 1, reference numeral 12 denotes a hammer for driving a seed piece;
3 is a hammer driving means. The hammer driving means 13 includes an air cylinder 13a, a bracket 13b attached to the tip of an output rod of the cylinder, a stopper 13c provided on the main body frame 1, and a kick spring 13d.

The hammer 12 is mounted on a bracket 13b so as to be vertically swingable, and is urged by a kick spring 13d in a direction in which the head 12a is lifted. When the output rod of the air cylinder 13a is retracted, the rear portion of the hammer 12 hits the stopper 13c, and the head 12a is pushed down and held at the retreat point. Also, the air cylinder 13a
When the output rod is pushed out, the rear part is separated from the stopper 13c, and the head 12a is lifted by the force of the kick spring 13d. When the head 12a comes on the traveling path of the cone 7, the rotation of the hammer 12 is restricted by the bracket 13b. Thereafter, the head 12a enters the guide hole 9a of the seed piece feeder by further pushing by the cylinder, and the head 12a is inserted into the guide hole 9a. Launch a seed piece. The seed piece feeder 9 has a slit on the lower side that allows the neck of the hammer 12 to enter, but depending on the shape of the hammer 12, even if the slit is eliminated, interference with the seed piece feeder 9 may occur. You can launch a seed piece without letting it go.

Reference numeral 14 in FIGS. 1 and 2 denotes a seed piece storage hopper. The hopper 14 incorporates a seed piece sending mechanism 15. The seed piece sending mechanism 15 used here is a cylinder cylinder 1
5a is vertically oriented (the tip of the planting machine is directed downward), and is moved up and down by a vibrator (not shown) or the like to vibrate the seed piece A flowing into the cylinder cylinder 15a from the entrance that spreads like a trumpet. Send in.

The seed piece introduction pipe 10 has an inlet end connected to the outlet of the cylinder 15a, and is repeatedly deformed by a change in the distance between the entrance and exit due to the vertical movement of the cylinder 15a. Here, the seed piece introducing pipe 10 is formed of a coil spring having a small coiling pitch as shown in FIG. 3 in order to smoothly perform the deformation and to make it possible to remove foreign substances clogged therein.

The seed piece storage hopper 14 may be placed on the ground independently of the main frame 1. Then, the capacity of the hopper can be increased and the number of replenishment of seed pieces can be reduced. In this case, the seed pieces are sent in by air or the like for reliable supply.

Reference numeral 16 in FIG. 1 is a safety device comprising a limit switch 16a and a push pin 16b for operating the limit switch. In addition to the above-described elements, the illustrated planting machine includes a valve (not shown) for switching the air supply path of the air cylinders 8, 11b, and 13a, and a retracting position of the cone 7, the seed piece feeder 9, and the hammer 12. Checking means (not shown) such as a sensor and a switch for checking is provided.

The operation of the seed piece planting machine shown in FIG.

First, the drill operation switch 2 is turned on to confirm that the drill is rotating. Next, the spike plate 1b is applied to the log, and the work start switch 3 is turned on. At this time, the operation does not start unless the push pin 16b is pushed in.

On the other hand, when the push pin 16b hits the wood and is pushed in, and the limit switch 16a is ON, the work starts, the output rod 8a of the air cylinder 8 is pushed out, and the cone 7 rotates and moves forward to rotate the wood. Drill holes in When the cone 7 reaches the end point of the stroke (the position indicated by the dashed line in FIG. 1), a signal flows from the position confirmation means, and the operating direction of the cylinder 8 is switched, so that the cone 7 moves backward. At this time, the drill continues to rotate, but the rotation may be stopped, or the drill may be reversed depending on the shape of the cone 7. When the cone 7 returns to the origin (the position indicated by the solid line in FIG. 1), a signal flows to activate the position switching means 13, and the seed piece feeder 9 moves from the position shown in FIG. 2 to the position shown in FIG. The seed piece taken into the guide hole 9a of the child is sent to the front of the cone 7, that is, to the entrance of the hole formed in the log. Thereafter, the hammer driving means 13 is operated based on the feed completion signal of the seed piece feeder 9, and the hammer 12 which has moved forward from the retreat point to the front of the cone 7 in the initial stage of the movement is further pushed out by the air cylinder 13a. The seed piece held by the child 9 is pushed forward from the guide hole 9a and advanced to the position indicated by the solid line in FIG. Thereafter, the air cylinder 13a is retracted, the hammer 12 returns to the origin, the seed piece feeder 9 is also returned to the origin, the next seed piece is fed into the guide hole 9a, and a series of operations is completed.

[0034]

As described above, the seed piece planter of the present invention applies the spike plate at the end of the main frame to the log.
By simply operating the switch, a series of operations from drilling to seed piece driving are performed automatically, so that the labor burden on the operator is small, and the seed pieces can be planted in the field easily and efficiently.

In the case where the drill motor and the seed piece storage hopper are made independent, the effect of reducing the size and weight of the planting machine is great.
Handling becomes easier.

Further, when the seed piece introducing pipe is formed by a coil spring, it is possible to prevent clogging of the pipe due to stagnation of foreign matter and fatigue and breakage due to repeated bending and extension of the pipe.
