The sprocket (40) is linked to the drive shaft (38) via a unit clutch (42) provided with a clutch lever (43).
), The eccentric pin (45) of the clutch shaft (44) is moved by the cam (41).
And the clutch pawl on the cam (41) side is separated from the clutch pawl on the sprocket (40) by the rotation of the cam (41) to disconnect the unit clutch (42), while the rotary case (21) The cam (41) can be disengaged by the cam (41) by a half turn so that two valleys of the cam (41) with which the eccentric pin (45) engages are provided at 180-degree intervals, and the rotary case (
21) Two stop positions are formed during one rotation. A sun gear (46) is loosely fitted to the planting claw drive shaft (38), and the sun gear (46) is fixed to the planting case (20) via a phase adjusting lever (47) so that the phase can be adjusted. And an idle gear (48) having the same number of teeth as the sun gear (46).
And a planetary gear (49). The idle gear (48) is supported via the intermediate shaft (50), and the planetary gear (49) is supported via the claw case shaft (51) fixed to the claw case (22) inside the rotary case (21). And the respective gears (46), (48), (49) are connected to the respective shafts (38), (50), (51).
The planetary gears (49) and (49) are always engaged with the sun gear (46) via idle gears (48) and (48). 46) is fixedly supported, and the rotary case (21) is rotated at a constant speed via the planting claw drive shaft (38), so that the planting claws (1) at both ends of the rotary case (21) are rotated.
7) The (17) is alternately moved to the seedling outlet (37) at the lower end of the seedling table (16), and the gears (46) () are interlocked with the rotation of the rotary case (21).
48) The claw case shaft (51) is rotated at a non-uniform speed via the (49), and the seedling mounting table (16) is rotated.
The rotation of the claw case shaft (51) is faster than the rotation of the rotary case (21) between the cutting of the seedling and the rotation of the rotary case (21), and the rotation of the rotary case ( The rotation of the claw case shaft (51) is made slower than the rotation of the claw case shaft (51), and the rotation of the rotary case (21) and the rotation of the claw case shaft (51) are substantially reduced near the seedling removal port (37) and near the rice planting portion. Equivalent, the locus of planting of the planting claw (17) is a rotary case (
21) It is configured to be formed in a vertically long oval shape at the front. [0011] A camshaft () is attached to the rotary case (21) via a position adjusting lever (52).
One end of 53) is rotatably fixed, and the middle of the cam shaft (53) is passed through the claw case shaft (51) to be loosely fitted to the push rod (54) connected to the forcible extruding claw (17a). The cam shaft (53) is connected via a push arm (55), and when the planting claw (17) enters the rice field, the push rod (54) via the cam shaft (53) and the push arm (55). Are advanced and the seedlings sandwiched between the planting claws (17) are pushed out into the soil by the pushing claws (17a). Further, as shown in FIG. 1, a flexible and elastic seedling extraction guide (56) is provided on both sides of the seedling extraction port (37), the upper end of which is fixed and the lower end is extended downward. (1
7) The seedling removal guide (56) forming a substantially same curve as the tip end locus is mounted on the seedling mounting table (16).
One of the planting claws (17) extending downward from both sides of the seedling removal outlet (37) and provided at both ends of the rotary case (21) is placed in the seedling removal guide (56), and the other planting claw (17). ) Are stopped above the float (34), respectively.
8) and the angle of attachment of the rotary case (21) to the upper stop cam (
41) The unit clutch (42) disconnection timing is set to adjust the position of each. The seedling holding portion of the front planting claw (17) which stops between the cutting of the seedling and the rice paddy surface is set from both sides of the seedling removal guide ( 56) to hold the seedlings of the planted claws (17), while holding the planted claws (17) and the claw case (
22) The lower side and the lower side of the rotary case (21) are positioned above the upper end of the planted seedling (57), and the planting claw (17) or the claw case (22) on the rear side of the fuselage pushes down the final planted seedling. In a device in which a planting claw is attached via a claw case (22) to a rotary case (21) that rotates at a constant speed in one direction, the rotary case (
In 21), the front planting claw (17), which is symmetrically disposed about the rotation axis, is stopped at least above the rice field surface, and the rear planting claw (17) is stopped at a position higher than the planted seedling height. And a planting case (20) for mounting the rotary case (21).
), The planting claw (17) is stopped so that the tip of the planting claw (17) is located above the bottom surface. The present embodiment is configured as described above, and the rotary case (21) is continuously rotated at a constant speed in one direction in the longitudinal direction of the fuselage around the planting claw drive shaft (38). The claw case shaft (51) rotates at a non-uniform speed via the gears (46), (48), and (49), so that the planting claw (17) is in the seedling cutting posture in front of the seedling removal port (37). The planting claws (17) were moved to the planting posture while rushing into the rice field, and the rotary case (2
The seedling of one plant is planted in a half rotation of 1). When the planting stop operation is performed via the clutch lever (43), the eccentric pin (45) comes into contact with the upper stop cam (41) and the unit is planted. The clutch (42) is disengaged, and as shown in FIG. 1, the front planting claw (17) is stopped in the seedling removal guide (56) above the float (34), and the planting claw (17) is stopped.
) Prevents the seedlings that have been cut off from falling off by the seedling removal guide (56), eliminates the occurrence of stock deficiency at the time of restarting planting, and raises the rear planting claw (17) above the float (34). The seedlings (57) are stopped at a position higher than the upper end to prevent the planting claws (17) from rushing into the rice field and disturbing the rice paddies, and to securely hold the cut seedlings on the planting claws (17). Further, the planted nail (17) or the nail case (22) is prevented from contacting the planted seedling and falling down. As is apparent from the above embodiments, according to the present invention, a planting claw (17) is attached via a claw case (22) to a rotary case (21) which rotates at a constant speed in one direction. In the apparatus, the seedling removal guide (56) which forms a substantially same curve as the trail of the tip of the planting nail (17) is provided.
) Is extended downward from both sides of the seedling removal port (37) of the seedling mounting table (16), and is stopped from the time of cutting the seedling mounting table (16) to the rice field surface. ) So as to sandwich the seedling holding portion from both sides with the seedling removal guide (56), and the rear planting claw (
17) is configured to be able to stop at a position higher than the planted seedling length , and at the end of the planting process, the forward planting claws (17) can be prevented from rushing into the soil and disturbing the rice field. The seedling removal guide (56) can prevent the falling of the seedling of the front planting nail (17), and can eliminate the occurrence of a lack of stock at the time of restarting planting. The front planting nail (17) can be planted.
Prevents the last planted seedling from being pushed down by the rear planting claw (17) immediately after stopping
Is a can shall.
