Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention comprises a seedling platform that moves back and forth from side to side, and a planting claw that takes out one seedling from the seedling platform and plants it. ! l
This invention relates to a planting device for a rice transplanter that continuously performs rice transplanting work.

"Prior Art" Conventionally, as shown in Japanese Patent Application Laid-Open No. 80-199309, a rotary case is provided which rotates at a constant speed in one direction, and planting claws are arranged symmetrically around the rotational axis of the rotary case. technology was developed.

"Problems to be Solved by the Invention" In the prior art, the sun gear and planetary gear that rotate the pawl case are eccentrically supported, the sun gear is fixedly supported, and the pawl case is rotated through the planetary gear by rotation of the rotary case. Because it was rotating at an inconstant speed, the planting trajectory of the planting claw was extremely limited, and to change the planting trajectory, it was necessary to change the eccentricity and number of teeth of the sun gear and planetary gear, and the planting claw support structure There have been problems such as the inability to easily obtain an appropriate planting trajectory.

``Means for Solving the Problems'' However, one aspect of the present invention is to attach a planting claw to a rotary case that rotates at a constant speed in one direction through a claw case, and also to attach a planting claw to a rotor case that rotates at a constant speed in one direction. The apparatus for rotating the pawl case is characterized in that an interlocking member is provided for rotating the sun gear in synchronization with the rotary case.

"Function" Therefore, the planting locus of the planting claw can be changed by changing the synchronized speed difference of the interlocking member without the need to make the sun gear and the planetary carrier eccentric as in the conventional case, and the orbital movement of the claw case can be changed. By rotating the sun gear based on
Any desired planting locus can be easily obtained by simply controlling the rotation of the sun gear, and the planting claw support structure can be changed and the planting function can be easily improved compared to the conventional method.
