[0011]
The transfer crank 40 is fixed to the right end of the drive shaft 25, and rotates together therewith.
A pair of seedling-planting cases 41 project upward from the pipe frame 17 on both sides of the seedling-planting gear box 19, and upper ends thereof are connected by a horizontal rod 42 (FIG. 5). A support rod 43 extending upward from the horizontal rod 42 is bent forward.
[0012]
A plurality of (horizontally 14) pots 44a are integrally provided on a flexible resin plate to form a seedling box 44 (FIG. 10). Putting floor soil in each pot 44a, sowing 2-3 grains of fir, covering the soil with water, germinates from the fir and grows seedlings. At this time, the roots extended in each pot 44a are entangled to form a root pot, and the seedlings in each pot 44a become independent for each plant. The seedling box 44 has a size of approximately 30 cm × 60 cm, and is provided with feed holes 44 b at the same pitch as the pots 44 a vertically arranged on both sides.
[0013]
A pair of seedling mounting stands 45A and 45B inclined forward and upward are arranged vertically and fixed to the supporting rod 43 (FIG. 5). Two seedling boxes 44 are placed on the seedling mounting tables 45A and 45B, respectively, side by side. The loaded seedling box 44 is detected by the switches 46A, 46B, 47A, 47B, and the result is input to a control device (not shown). Motors 48A and 48B, which are operated by the output of the control device, are provided at the outlets of the seedling mounting tables 45 and 45B, respectively, so that the rollers 49A and 49B are driven so that the seedling box 44 is fed out later.
[0014]
A pair of rails 50 is fixed to the inner surface of the seedling case 41, and is configured to support both sides of the seedling box 44 (FIGS. 6 and 7). That is, each of the rails 50 is formed in an L-shaped cross section by the upper surface 50a located above the sending hole 44b of the seedling box 44 and the side surface 50b located to the side thereof. The rear part of the rail 50 protrudes upward from the seedling plant case 41, the lower part bends forward, and the end reaches the receiving box 52 by the empty box rail 51. The guide rail 53 is provided between the seedling mounting tables 45A and 45B and the rail 50, and guides the seedling box 44 that the rollers 49A and 49B have drawn out to the rail 50. A push rod 54, which is pushed counterclockwise around a shaft 54b by a spring 54a, is disposed inside the rail 50, and its lower end presses both side portions of the seedling box 44 inside the upper surface 50a. .
[0015]
The conventional seedling mounting tables 45A and 45B are configured so that the seedling boxes 44 placed on the upper seedling mounting table 54A are fed out preferentially for convenience of replenishing the seedling boxes 44. Therefore, the seedling box 44 of the lower seedling mounting table 54B may be held for a long time, and the seedlings may be dried and cannot be used for use. On the other hand, the time when the seedling box 44 is mounted and the switches 46A and 46B are turned “ON” is stored in the control device, and the motors 48A or 48B of the switches 46A or 46B which have been turned “ON” first are driven in order. Since the seedling box 44 placed first is taken out first, the fear is eliminated. Note that the rear (right) seedling box 44 is forcibly fed out by the motors 48A and 48B, and the front (left) seedling box 44 is sent out by its own weight thereafter. When the switch is extended, the switches 46A and 46B are turned "OFF" and then turned "ON" again. In addition, the motor 48A or the motor 48B can be operated according to the operation status of the switches 46A and 46B and the switches 47A and 47B according to a certain program.
[0016]
The transfer device for the seedling box 44 is made as follows. The lever 55 is rotatably mounted on the left surface of the seedling plant gear box 19 by a shaft 55a. When the rotating box feed arm 36 comes into contact with the lever 55, the lever 55 turns clockwise, and when it is released, it is pulled back by the spring 56 (FIG. 4). (FIG. 5). One end of the bell crank 57 is connected to the lever 55 by a rod 58, and swings around a shaft 57a in the opposite direction. The lower end of the feed rod 59 is attached to the pin 57b at the other end of the bell crank 57, and is pulled counterclockwise by a spring (not shown) so that the claw 59a at the upper end protrudes inward from the hole 50c of the rail 50. The bell crank 57 swings up and down. The stop rod 60 is rotatably attached to the rear part of the rail 50 by a pin 60b, and is pushed clockwise by a spring 61 so that a claw 60a below the pin 60b protrudes into the rail 50 from the hole 50c. I have. The claw 59a and the claw 60a have an edge perpendicular to the moving direction of the seedling box 44 and an inclined edge on the lower side and the upper side, respectively, so that they can simultaneously enter the feed hole 44b.
[0017]
That is, the claw 59a and the claw 60a enter the same feed hole 44b of the seedling box 44 at the position where the pin 57b is raised. When the pin 57b is lowered by the swing of the bell crank 57, the claw 59a pulls down the seedling box 44. At this time, the claw 60a escapes from the feed hole 44b at the upper oblique edge and moves to the feed hole 44b above it. Thereafter, the bell crank 57 swings in the opposite direction, and the pin 57b starts to rise. Then, since the seedling box 44 is stopped by the claw 60a, the claw 59a escapes from the above-mentioned sending hole 44b at the upper oblique edge and moves to the upper sending hole 44. Due to this repetition, the seedling box 44 is intermittently sent downward at every interval above and below the pot 44a. At this position, the seedlings in the pot 44a project rearward.
[0018]
The seedling extruder is made as follows. Extrusion pins 62 are arranged in the front-rear direction between the left and right seedling plant cases 41 (FIG. 5). The number of the push pins 62 is equal to the number of the pots 44a arranged side by side, and when the push lever 38c swings, the arm 64 swings by the rod 63 and moves back and forth. Then, when moving later, it rushes into the pot 44a of the stopped seedling box 44, and pushes out the root pot with the seedling behind the rail 50.
[0019]
A carrier 65 is arranged behind the rail 50 (FIG. 1), and is adapted to receive the seedlings extruded from the pot 44a and carry it to the next belt conveyor 66. The carrier 65 is attached to the seedling case 41 by a pair of links 67 on the left and right sides, and the rotation of the transfer crank 40 reaches the link 67 via the rod 68 (FIG. 4), and maintains the same posture by the swing. To move up and down.
[0020]
The seedlings sent by the carrier 65 are transferred to a belt conveyor 66 by a scraping tool (not shown). The belt conveyor 66 is configured as a pair of left and right sides (FIG. 4), rotates by rotation of a shaft 69 projecting backward from the pipe frame 17, and carries seven seedlings at equal intervals to the outside.
The implant frame 70 extends rearward from the pipe frame 17, and the implant drum 71 provided at the side of the rear portion rotates counterclockwise in FIG. 1 by the rotation of the main shaft 20. The implantation rod 72 projects from the implantation drum 71 and rotates, so that the seedlings that have reached the outer end of the belt conveyor 66 are sequentially pushed down and transplanted to the mud.
[0021]
When the seedling box 44 sent by the claw 59a goes down to a predetermined position, the next seedling box 44 is fed by the motor 48A or 48B and added to it as described above.
The above operation is repeatedly performed, and the seedlings of the pot 44a are continuously transplanted between certain strains. The seedling box 44 from which the seedlings have been extracted is pushed by the next seedling box 44 and reaches the receiving box 52 through the empty box rail 51.
[0022]
Adjustment shafts 73 are rotatably attached to the lower portions of the respective implantation frames 70, and are configured to swing by operating the adjustment lever 73a. A plurality of floats 74 are arranged side by side, and a rear pin 74a is attached to a rear end of an arm 73b extending rearward from the adjustment shaft 73, so that the traveling vehicle body 1 slides on a mud surface. Each of the floats 74 has a front portion projecting sideways, and the projecting portion preliminarily lands a portion where the seedling is transplanted.
[0023]
When the seedling clutch in the clutch case 22 is constituted by a fixed-position stop clutch, which is turned off, the operation of each part of the seedling plant 2 is simultaneously stopped at a predetermined position. Then, the seedling plant 2 is configured as a multi-row plantation as described above, and the operation of the claws 59a, the pushing pins 62, and the carrier 65 is performed by operating the respective seedling gear boxes 19 in order to equalize the load of the engine 8. (Or between the two at the center and the two at the left and right), any of the box feed arms 36 hits the lever 55 or the push pin 62 In some cases, the seedling box 44 cannot be taken out while being inserted into the pot 44a.
[0024]
With the following configuration, the inconvenience is eliminated. The lever 55 is provided with a handle 55b so that the bell crank 57 can swing with the handle 55b more than the swing by the box feed arm 36. When the box feed arm 36 is separated from the lever 55 and stopped, when the handle 55b is turned counterclockwise greatly in FIG. 5, the feed rod 59 rises greatly and its claw 59a is out of the hole 50c of the rail 50. 7 (FIG. 7), the state of being disengaged from the feed hole 44b is maintained, and the bevel 60c at the lower end of the stop rod 60 is pushed by the pin 57b. It comes off from the feeding claw 44b. Then, when the aze clutch 32 is turned off, the box feeding arm 36 is separated from the lever 55, and the rotation of the drive shaft 25 is stopped at a position where the pushing pin 62 is removed from the pot 44a.
[0025]
In the above configuration, when the operation of the seedling plant 2 is stopped, each aze clutch 32 is turned off, and then the seedling clutch in the clutch case 22 is turned off. Then, all the operations of the seedling plant 2 are stopped. When removing the seedling box 44 on the way, the handles 55b are operated to separate the claws 59a and 60a from the feed holes 44b as described above. Then, the seedling box 44 can be pulled up lightly.
[0026]
The support of the seedling plant 2 is configured as follows. A pedestal 75 is formed by assembling squares into a square (FIG. 8), and the casters are mounted on the lower surface to move on the ground. Two pillars 77 extend upward from the front part, and a slightly wide V-shaped receiving member 77a is provided at the upper end. Three pipes 78 are fixed to the rear part at equal intervals in the vertical direction. A support rod 79 is inserted into each pipe 78 from above, and a V-shaped receiving member 79a is fixed to each upper end.
[0027]
The seedling plant 2 is raised by projecting the piston rod 14a of the seedling plant, and the support table is pushed under the planting device 2. Each supporting rod 79 is pulled up, and the receiving member 79a is aligned with the adjusting shaft 73, and a pin 80 is inserted into this to stop them (FIG. 9). After removing the propeller shaft 23 from the input shaft 24 and separating the hook 16 from the pin 15b, the oil in the hydraulic cylinder 14 is gradually returned to the tank, and the seedling plant 2 is slowly lowered. Then, the respective support rods 79 descend in the pipe 78 in accordance with the descending of the seedling planting apparatus 2. When this lowering proceeds and the lower end of the support rod 79 hits the bottom of the pipe 78, the seedling plant 2 starts to rotate counterclockwise around the adjustment shaft 73. With this rotation, the connecting pipe 81 connecting the seedling-planting gear boxes 19 descends and hits the receiver 77a. Thereafter, the elevating frame 13 is lowered independently, the receiving portion 13a is separated from the pin 15a, and the seedling plant 2 and the traveling vehicle body 1 are separated. In addition, since the fertilizer is attached in the figure, its hose is removed in advance.
[0028]
When connecting the seedling plant 2 to the traveling vehicle body 1, the procedure is reversed. That is, the traveling vehicle body 1 on which the elevating frame 13 is descending approaches the seedling planting apparatus 2 received by the support table, and the receiving portion 13a is positioned below the pin 15a, and then the elevating frame 13 is raised. .
[0029]
