[0003]

[Problems to be solved by the device]

 However, the above-mentioned conventional one has a drawback that it lacks maneuverability because a large-capacity water tank has to be mounted on the aircraft due to constant watering.

Further, when soil is clogged between the planting nails, there is a disadvantage that there is no device for removing the soil and the planting nails are clogged with the soil so that the seedlings cannot be caught securely.

The present invention solves the above drawbacks and waters the seedlings when the planting nails rise above the ground, and at the same time, uses this water to wash away the soil clogged between the planting nails. The purpose is to do so.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a transplanter for connecting a base end of a transplantation rod to a drive shaft and elevating an openable / closable planting claw provided at a tip of the transplantation rod to plant seedlings. Attach the irrigation pipe to the irrigation pipe, fix the outlet side end of the irrigation pipe toward the planting claw, and connect the inlet side of the irrigation pipe to the water tank mounted on the transplanter via the water supply pump. The plunger of the water feed pump is intermittently movably connected to the drive shaft of the transplanter, and the water feed pump is operated to deliver water to the planting nail only when the planting nail is raised.

[0007]

[Action]

 In the irrigation system of the present invention configured as described above, the plunger makes an intermittent motion with the rotation of the drive shaft, and when the planting claw rises, the water in the water tank is sent to the planting claw for planting. The nails are washed and the planted seedlings are watered. After irrigation, the water supply to the planted nail is stopped while the planted nail further rises and then descends.

The implanting rod 22 is fixed to the tip of the implanting rod 6 downward, the implanting claw stator 7 is fixed to the lower end of the implanting rod 22, and the implanting claw mover 8 is attached to the implanting claw stator 7. Opposite.

Further, a projecting piece 33 and a projecting piece 34 are provided on the tip end of the implanting rod 6 and near the base end with a little space therebetween, and the bell crank 30 is pivotally attached to the projecting piece 33. One piece 30a of the bell crank 30 is connected to the rod 28 attached to the arm 27 integral with the planting claw mover 8, and the other piece 30b of the bell crank 30 is connected to the rod 9. The rod 9 is arranged along the lower surface of the implanting rod 6, and a fulcrum 10b at the base end of the rod 9 is pivotally attached to the movable cam 10, while the tip end thereof is attached to the projecting piece 34 of the implanting rod 6. The rod 9 is slidably fitted into the attached rod guide 31, and a spring 32 is wound and stretched between the other piece 30b of the bell crank 30 and the rod guide 31 to move the rod 9 toward the tip of the implant rod 6. Urge towards.

The movable cam 10 has three pins 17, 18, and 19 pivotally mounted on one side surface thereof. The pin 19 is attached to the outer end of the shaft 37 which is inserted into the collar 40 attached to the tip of the movable cam 10. The shaft 37 has a coil spring 38 stretched between it and the pin 19, and a bolt 39 is screwed to the inner end of the shaft 37 to prevent the shaft 37 from coming out of the movable cam 10 by the elastic force of the coil spring 38. .

Then, the fixed cams 15 and 16 are fixed to the body of the transplanter so that the fixed cam 16 projects forward of the fixed cam 15. The fixed cams 15 and 16 are brought into contact with and separated from the pin 19. Further, the fixed cam 36 is fixed to the vehicle body of the transplanter located above the fixed cam 15, and the fixed cam 36 is brought into contact with and separated from the pin 17. Then, as shown in FIG. 3, an inclined surface 16a, which is cut upward from the inner surface toward the outer surface, is provided on the upper surface of the fixed cam 16 facing the movable cam 10.

On the other hand, as shown in FIG. 4, a bevel gear 44 is connected to the drive shaft 24 of the engine via a sprocket 41, a chain 42, and a sprocket 43. The bevel gear 44 meshes with a bevel gear 45 fixed to a shaft 46. A sprocket 47 is fixed to the other end of the shaft 46, a sprocket 48 is provided on the side of the sprocket 47, and a sprocket 49 is provided below. The seedling feeding carrier chain 50 is wound around these sprockets 47, 48 and 49, and the sprockets are similarly arranged at the rear of the sprockets 47, 48 and 49, and the chain is wound parallel to the chain 50. Then, the front end and the rear end of a large number of seedling stands 51 are respectively fastened between these two chains, and at the same time, the spring type seedlings for setting the seedlings 5 are set on the upper surface of each seedling stand 51. Install the holder 52. Further, the plunger 21 for operating the water supply pump 20 is connected to the drive shaft 24 via the crank arm 57 and the link 58. A long hole 59 is formed in the plunger 21, and a pin 60 fixed to the link 58 is inserted into the long hole 59.

The water supply pump 20 is fixed to the side surface of the machine body and operates by raising and lowering the plunger 21 as shown in FIG. 11, and the suction port 61 is mounted on the side of the machine body via the irrigation pipe 62. It is connected to the tank 63, and the irrigation pipe 65 is attached to the discharge port 64. The tip of the irrigation pipe 65 faces above the planting claw stator 7 and the planting claw mover 8 and fixes the seedling 5 to a position on the ground even when planting it in the ridge 3.

The water supply pump 20 has an inverted T-shape, the upright portion is a cylinder 66 that allows the plunger 21 to slide up and down, and the horizontal portion is a water passage with both ends slightly widened. Check valves having balls 69 and 70 biased by springs 67 and 68, respectively, are attached to the horizontal portions to control the intake and discharge of water.

Since the drive shaft 24 of the engine is rotated and the power is transmitted to the implanting rod 6 via the crank arm 25 and the link 26, the implanting rod 6 has its base portion 6a. Reciprocates up and down on the fulcrum.

As the implanting rod 6 rises, the pin 17 of the movable cam 10 slides on the cam surface of the fixed cam 36 (FIG. 6), and the entire movable cam 10 rotates clockwise around the fulcrum 10a to rotate the coil spring 32. Since the rod 9 is pulled against the pulling force of, the planted claw mover 8 connected to the tip of the rod 9 is fully opened. Here, the seedling feeding section 4 moves the seedlings 5 to the lower seedling feeding position and applies them to the planted nail stator 7.

As the movable rod 10 descends from the top dead center, the movable cam 10 rotates counterclockwise along the sliding contact surface of the fixed cam 36 due to the tensile force of the coil spring 32 (FIG. 7). 9 moves in the distal direction, the planting claw mover 8 closes, and the planting claw stator 7 holds the seedling 5 with it.

As the implantation rod 6 further descends, the closed tip end of the planting claw stator 7 on the ground surface goes into the ground. At this stage, the pin 19 of the movable cam 10 contacts the inclined surface 16a provided on the inner surface of the fixed cam 16 on the movable cam 10 side as the implanting rod 6 descends, and is pushed into the movable cam 10 side. After that, it moves along the inner surface of the fixed cam 16 by tracing.

At the bottom dead center of the implanting rod 2, the pin 18 slides on the cam surface 15a of the fixed cam 15 (FIG. 8), and as a result, the movable cam 10 as a whole rotates in the clockwise direction. Then, the planting claw mover 8 is fully opened and the seedling 5 is released. Here, the pin 19 comes off the side surface of the fixed cam 16 and is restored to the initial length by the tension of the coil spring 38, and then comes into sliding contact with the cam surface 16a on the upper surface of the fixed cam 16 (FIG. 9).

When the implanting rod 6 starts to move up, the pin 19 ascends while rolling on the cam surface 16a of the fixed cam 16 (FIG. 10). After slightly rotating counterclockwise according to the cam surface 16a, the pin 19 does not rotate and rises until the cam surface 16a of the fixed cam 16 protruding forward is removed upward. For this reason, the planting pawl mover 8 is lifted while being half opened.

After the stud 6 is further lifted and the ridged surface with the mulch is removed, the pin 19 is eventually removed from the upper end of the cam surface 16 a of the fixed cam 16 so that the movable cam 10 is closed. It rotates counterclockwise by the tension of the il spring 32, and the planting pawl mover 8 closes via the rod 9 (FIG. 5). In this state, the pins 17, 18 and 19 are separated from each other without coming into contact with the cams 36, 15 and 16, and the tension of the coil spring 32 is concentrated on the planting pawl mover 8.

The implantable rod 6 thereafter reaches the top dead center again. The above operation is repeated below.

On the other hand, simultaneously with this operation, as the drive shaft 24 of the engine rotates, the crank arm 57 attached thereto rotates, and the link 58 changes the rotational motion into a linear motion to move the plunger 21 up and down. While the pin 60 at the tip of the link 58 is moving through the long hole 59 of the plunger 21, the pin 60 does not push or pull the plunger 21, so the plunger 21 does not move up and down. As a result, the feed pump 20 does not operate over the entire rotation of the crank arm 57, but rather during the stroke during which the pin 60 moves through the slot 59.

Therefore, after planting the seedlings 5, the vertical movement of the plunger 21 and the planting claw stator 7, the planting claw stator 7, so that the planting claw stator 7 and the planting claw mover 8 irrigate when they come out of the soil. If the pitch of the vertical movement of the attached claw mover 8 is set to match, the planting claw stator 7 and the planting claw mover 8 will be used for irrigation when they leave the soil halfway and continue the rising stroke. About 10 cc of water is blown out from above the planting claw stator 7 and the planting claw mover 8 to wash the soil such as by washing off the soil clogged between the planting claws 7 and 8 and to irrigate the seedlings 5.

In the above-described embodiment, the pin 60 is fixed to the link 58, and the elongated hole 59 is formed in the upper portion of the plunger 21. On the contrary, the elongated hole is provided in the link 58 and the upper portion of the plunger 21 is formed. Even if the pin is fixed and the pin is inserted through this elongated hole and the link 58 and the plunger 21 are connected, the effect of the present invention is similar.

[0029]

[Effect of the device]

 In the present invention, since the plunger of the water supply pump is connected to the drive shaft that operates the planting claw, watering can be performed according to the transplanting pitch of the seedlings. In addition, the long hole in the blanker allows intermittent irrigation only when the planting nail rises and comes out of the soil, so that not only can it be discharged intensively to wash the planting nail, but also after transplanting. Water can be reliably supplied to the seedlings. Furthermore, since the water is not wasted and a large-capacity water tank does not have to be mounted on the machine body, the mobility of the transplanter is good.
