Conventionally, this type of rotary seedling planting device has been disclosed, for example, in Publication of Utility Model Publication No. 47-35534 and Publication of Utility Model Publication No. 47-28104.
As described in Japanese Patent Publication No. 49-17806, etc., a rotating shaft that is rotationally driven by power transmission from a power source is supported in the body of the rice transplanter in a substantially horizontal direction, and the rotation is The rotating body attached to the shaft has a planting shaft arranged at a plurality of locations on the circumference around the rotating shaft so as to rotate once in a direction opposite to the rotation direction of the rotating body during one rotation, A planting rod is supported parallel to the rotating shaft, and each planting shaft has a seedling dividing claw body at its tip, and the seedling dividing claw body on the planting rod faces the direction of the seedling platform. It is configured such that it is attached at its base.

る等の利点を有する。 This conventional rotary seedling device is configured as described above, so that each planting rod can be moved up and down while facing the direction of the seedling stand. Compared to the well-known crank-type seedling planting device described in
It has advantages such as less vibration and improved seedling planting speed.

In other words, if the length from the center of the planting axis to the tip of the split claw body in each planting rod is increased, the distance between the rotation axis at the center of the rotating body and each planting axis must be increased. As the rotation radius of the rotating body increases, the size of the seedling planting device increases. Also, if the length of each seedling planting rod is shortened, the rotation radius of the rotating body becomes smaller, making the seedling planting device smaller and smaller. Although the weight can be reduced, the height from the field to the rotating body is reduced, which causes the problem that the rotating body sinks into the field or comes into contact with the float.

In order to achieve this object, the present invention provides a rice transplanter with a rotary shaft that is rotatably driven by power transmission from a power source in the body of the rice transplanter, and is arranged horizontally and horizontally in a direction substantially parallel to the moving direction of a seedling stand supported on the body. The rotating body, which is pivotally supported by the rotating body and attached to the rotating shaft, has a plurality of parts on a circumference centered on the rotating shaft, which rotate once in a direction opposite to the rotational direction of the rotating body during one rotation of the rotating body. The planting shaft made in the above manner is supported in parallel with the rotating shaft,
A planting rod having a seedling dividing claw at its tip is placed on the protruding portion of each planting shaft from the rotary body at the base thereof with the dividing claw of each planting rod facing in the direction of the seedling platform. In the seedling planting device, the outer surface of each of the planting rods on the side opposite to the rotating body is moved so that the outer surface of the base portion of the planting rod is moved closer to the rotating body by the split claw body. The inner surface of the rotor is shifted to the inner side of the rotating body.

In this way, the outer surface of each planting rod on the side opposite to the rotating body is separated from the inner surface of the rotating body side of the split claw body so that the outer surface at the base of the planting rod is divided in the direction in which the rotating body approaches. When the split claw body of each planting rod is shifted to the inner part, the tip of the split claw body does not come into contact with the base up to the outer surface part of the base of the planting rod. Since it can be extended with It can be done.

りすることを防止できると云う効果を奏する。 Therefore, according to the present invention, in a state where the distance between the axis of rotation at the center of the rotating body and each planting axis, that is, the rotation radius of the rotating body is shortened,
Since the length from the center of the planting shaft of each planting rod to the tip of the split claw body can be increased, the size and weight of the seedling planting device can be reduced, and as a result,
The rice planting area can be made smaller and lighter, and the rotating body can be prevented from sinking into the field or coming into contact with the float.

おいて圃場面１５より上昇するのである。 In this configuration, when the rotating body 4 revolves around the rotating shaft 3 in the right direction of the arrow A, the transmission case 1
As the rotating body 4 revolves, the intermediate gear 12 meshing with the sun gear 5, which cannot rotate, rotates in the right direction of arrow B by the same rotation angle as the rotation angle of the revolution. Interlocking gears 13 and 14 are connected to this intermediate gear 12.
The planting shaft 7 interlocked with the intermediate gear 1
2 rotates in the left direction of the arrow C, that is, in the opposite direction to the revolution direction of the rotating body 4. Therefore, the planting rod 8 attached to the planting shaft 7 has its split claw body 9 as shown in FIG. The seedling table 10 rotates around the rotation axis 3 while facing the direction of the seedling table 10. During this rotational movement, the seedling table 10
When descending from top to bottom on the side facing the top, the tip 9a of the splitting claw body 9 divides only one seedling from the seedling pine on the seedling stand 10, and then it moves to the field scene 15 near the lower limit of descent. After planting, it rises above the field scene 15.

のである。 In this case, the outer surface 8' of each planting rod 8 on the opposite side to the rotary body 4 is connected to the outer surface 8a' of the base 8a of the planting rod 8, and the outer surface 8a' of the base 8a of the planting rod 8 is connected to the rotor 4. By shifting the split claw body 9 to a part inside the inner surface 9' of the rotating body 4 in the direction approaching the split claw body 9, the split claw body 9 on the planting rod 8 can be moved so that its tip 9a is on the side of the planting rod 8. Since it can be extended to the part located on the outer surface 8a' of the base 8a without contacting the base 8a, the split claw body 9 can be extended from the center of the planting shaft 7 in each planting rod 8.
The length dimension from the tip 9a to the tip 9a can be increased without increasing the inter-axial distance L from the rotating shaft 3 at the center of the rotating body 4 to each planting shaft 7.

If the eccentric gear is configured to be eccentric by an appropriate dimension (e) from the rotation center of the planting shaft 7, the leftward rotation of the planting shaft 7 accompanying the rightward revolution of the rotating body 4 will be within one rotation. Because the revolution speed of the rotor 4 is faster or slower than the revolution speed of the rotor 4 due to the diameter difference between the eccentric interlocking gears 13 and 14, the rotation speed of the planting shaft 7 is The period when the rotation of the planting shaft 7 to the left becomes slow is the period when the planting rod 8 descends to approach the field scene 15, and the period when the rotation of the planting shaft 7 in the left direction becomes fast is the period when the rotation of the planting rod 8 approaches the upper limit of the rise of the planting rod 8. By setting each planting rod 8 to correspond to the rising period, each planting rod 8
When descending to approach , it rotates to the left later than the revolution of the rotating body 4 and changes its attitude downward, and as it approaches the upper limit of ascent, it gradually moves to the left compared to the revolution of the rotating body 4 Since each planting rod 8 rotates on its own axis and changes its posture upward, the closed loop of the motion locus at the tip 9a of the split claw body 9 is an elliptical closed loop curve elongated in the vertical direction, as shown by the two-dot chain line in FIG. It becomes 16.

However, the sun gear 5 may be replaced with a pulley, and a cross-type belt may be used between the pulley and the planting shaft 7, etc.
Needless to say, other means may be used to configure each planting shaft 7 to make one rotation in the opposite direction during one rotation of the rotating body 4. However, the present invention is not limited to this, and it is also possible to arbitrarily make the number of times three or more in the circumferential direction.
