Thus, the buffer spring 66 is compressed between the bolt 68 and the ceiling 33 to relieve the impact during retraction.
[0020]
Next, the operation and action of the raw tree inoculation apparatus of this embodiment will be described below. First, the log 1 is placed on the log receiving part 3 of the pair of centering devices 4 from the log placing table 29, and the start button of the device is pushed. Then, the log receiving portion 3 is raised by the air cylinder 15 and the horizontal centering member 2 is raised until it hits the stopper, and at that position, the upward movement of the horizontal centering member 2 is stopped. This stop position and the position of the central axis in the longitudinal direction of the log 1 are always substantially constant.
[0021]
Then, a pair of clamp apparatus 6 is operated and the both ends of the log 1 are hold | maintained from both sides. The centering device 4 is automatically positioned by an air cylinder 15 and has a simple structure that does not require the thickness detection or sequence control of the log 1.
[0022]
Thereafter, the clamp device 6 holding the log 1 is horizontally moved by the drive device 5 to a processing position below the drilling machine 7. Next, due to the operation of the air cylinder 19 of the drill machine 7, the drill machine 7 is lowered, and at the same time the positioning member 25 is also lowered. When the positioning member 25 comes into contact with the log 1, the drilling machine 7, the feed guide block 21, the air cylinder 19, and the positioning guide block 23 are integrated to follow the position of the side surface of the curved log 1. Swing back and forth as the center. As a result, the drill 7 a of the drill machine 7 is also swung and positioned at the center of the predetermined position of the log 1. Further, when the piston rod 19a of the air cylinder 19 protrudes, the positioning guide block 23 descends against the spring, the drill machine 7 further descends, and a hole is made at a predetermined position of the log 1. After a predetermined hole is drilled, the drilling machine 7 is temporarily raised by the air cylinder 19. Then, by the clamping device 6, the log 1 is rotated around a predetermined angle axis, and the drilling machine 7 is lowered again by the same operation as described above, and drilling is similarly performed.
[0023]
After this processing is performed for one row around the log 1, the clamp device 6 moves in the longitudinal direction by the distance between the drill machine 7 and the inoculator 8 while holding the log 1. Then, the hole opened by the drill machine 7 is located below the inoculator 8. After that, the operation of the inoculator 8 is similar to the drill machine 7, the inoculator 8 is lowered, and the positioning member 25 is also lowered at the same time, swinging back and forth about the swing shaft 12 along the side of the log 1. As the positioning member 25 moves, the accommodation portion 32 of the inoculator 8 also swings back and forth and is positioned at the center of the predetermined position of the log 1.
[0024]
Next, the air cylinder 44 of the compacting device 36 of the inoculator 8 is activated and the rod 42 protrudes from the retracted position. Thereby, the pressing part 38 moves toward the receiving part 40, moves while pushing the bacteria carrier powder 30 existing in the middle of the movement, and pushes the bacteria carrier powder 30 between the end surface part 40a of the receiving part 40. Solidify. At this time, the stick 34 is retracted to the highest position. Further, at this time, since the engaging pin 50 moves together with the pressing portion 38, the engaging piece 52 is rotated by the engaging pin 50, the stirring blade 46 is also rotated through the rotating shaft 48, and the bacteria carrier powder 30 is rotated. Stir moderately.
[0025]
Then, the stick 34 is lowered, the fungus carrier powder 30 solidified between the pressing part 38 and the receiving part 40 of the compacting device 36 is pushed into the cylindrical part 41, and the further compacted fungus carrier powder 30 is converted into the raw wood. Press fit into hole 1. At this time, the fungus carrier powder 30 is also stirred by the stirring piece 35 provided on the thrust bar 34. The pressing portion 38 is returned to the retracted position by the air cylinder 44. At this time, since the back surface portion 38b of the pressing portion 38 is formed in an acute angle shape, the fungus carrier powder 30 has less resistance.
[0026]
Here, the amount of the fungus carrier powder 30 to be inoculated is set to a predetermined amount by adjusting the position of the lower end portion of the thrust bar 34 in the retracted state which is the ascending position. In this adjustment, since the engaging portion 54a of the connecting member 54 is loosely fitted to the male screw portion 34a, the screwing position of the height adjusting nut 62 as the position adjusting member and the male screw portion 34a of the thrust bar 34 is adjusted. Then, the height at the retracted position of the thrust bar 34 is set. That is, the air cylinder 56 is operated, the engaging portion 54a of the connecting member 54 comes into contact with the back surface of the height adjusting nut 62, and the thrust bar 34 is lifted and retracted. The position is set at the screwing position of the height adjusting nut 62. Moreover, the nut 60 for stoppers sets the position of the front-end | tip part in the protrusion position where the thrust bar 34 descend | falls. Thereby, the width of the space formed between the pressing portion 38 and the receiving portion 40 is adjusted, and the amount of the fungus carrier powder 30 can be adjusted.
[0027]
The inoculation by the inoculator 8 is planted and raised by the number of holes formed around the log 1. At this time, a drilling process similar to that described above is performed by the drill machine 7 next to the inoculation position.
[0028]
Thereafter, the clamping device 6 further positions the hole inoculated with the log 1 held below the wax sealer 9. After that, the operation of the wax sealer 9 is the same as that of the drill machine 7, and the wax sealer 9 is lowered, and the positioning member 25 is also lowered at the same time. Then, the wax sealer 9 also swings back and forth in accordance with the movement of the positioning member 25 swinging back and forth around the swing shaft 12 following the side surface of the log 1, and the predetermined position of the log 1 is set. Positioned in the center. Then, the sealing device 9a of the wax sealing machine 9 descends, and wax is poured into the upper part of the hole in which shiitake mushrooms are planted in the raw wood 1, and the wax is raised by sealing the number of holes.
[0029]
When the processing of all the above steps is completed over the entire length of the whole circumference of the log 1, the clamp device 6 holding the processed log 1 is moved to the right by the drive device 5, and at the position of the hoda tree carry-out portion 60. Stopping, the clamping device 6 is unclamped, and the processed raw wood 1 falls to the hodder carrying-out part 60, and one cycle of inoculating the raw wood 1 is completed.
[0030]
According to the raw tree inoculation method and apparatus of this embodiment, it is possible to inoculate a predetermined amount of shiitake mushrooms accurately on the automatically drilled raw tree 1, and there are too few or too many inoculations. There is nothing to do. Further, the drill machine 7 and the inoculator 8 have a simple structure in which the positioning member 25 swings following the log 1 and is positioned correctly even with respect to the log 1 having a different thickness and being curved. Is done.
[0031]
Next, a raw tree inoculating apparatus according to a second embodiment of the present invention will be described with reference to FIGS. Here, the same components as those in the above embodiment are denoted by the same reference numerals, and description thereof is omitted. In this embodiment, a sheath member 70 made of foamed resin or the like is fitted into the rod 42 to which the pressing portion 38 is attached, and the rod 42 and the sheath member 70 are integrated to reciprocate within the housing portion 32. Is provided. Here, the length in the longitudinal direction of the pressing portion 38 is larger than the diameter of the rod 42, and the diameter of the sheath member 70 is approximately equal to or less than the length in the longitudinal direction of the pressing portion 38 and is about ½ or more. is there. Further, the rod 42 and the sheath member 70 are inserted through a through hole 49 of a mounting member 45 provided in the housing portion 32, and the through hole 49 is formed to be substantially equal to the diameter of the sheath member 70, and the fungus carrier in the housing portion 32. The powder 30 does not spill out, and the friction between the sheath member 70 and the through hole 49 is small.
[0032]
In the raw tree inoculation method and apparatus according to this embodiment, a sheath member 70 is inserted into a rod 42 that reciprocates in a fungus carrier powder 30 such as sawdust, and the diameter of the rod 42 is set to the length of the pressing portion 38. By being small, the bacteria carrier powder 30 is prevented from being pressed behind the pressing portion 38 by the backward movement of the pressing portion 38. That is, the thickness of the sheath member 70 with respect to the thickness of the rod 42 is set to a thickness of 1/2 or more with respect to the length of the pressing portion 38 in the longitudinal direction. Even when the reciprocating operation is performed, it is difficult to press and solidify the fungus carrier powder 30 behind the pressing portion 38, thereby effectively preventing the density deviation of the fungus carrier powder 30 in the housing portion 32. The thickness of the sheath member 70 may be approximately equal to or less than the length in the longitudinal direction of the pressing portion 38 and may be 1/2 or more.
[0033]
According to the inoculation device of this embodiment, the fungus carrier powder 30 on the back side of the pressing portion 38 is hardly pressed even by the reciprocating motion of the pressing portion 38 of the pressing device 36, and the density of the fungus carrier powder 30 is unevenly distributed. It suppresses and enables uniform inoculation.
[0034]
Note that the pressing portion of the compacting device may have any shape that surrounds the side surface of the thrust bar, such as a substantially arc shape at the end surface portion. In this case, the substantially arc shape means that the end surface portion is a U-shape or a triangle, Other polygonal shapes may be used. Further, the positions for drilling and the like may be formed over the entire circumference of the raw wood, and the adjacent drilling positions may be moved by a half pitch. Furthermore, the drilling position may be formed in a spiral shape.
[0035]
