粉粒体繰出し装置とを備えた田植機に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention has a plurality of planting claws that are pivotally supported on a planting case that is rotationally driven around a horizontal axis, thereby controlling the rotation of the planting case. A seedling planting device configured such that each planting claw sequentially takes out and plants seedlings from a seedling take-out port of a seedling stand, and an agricultural granular material feeding device provided above the planting case. Regarding rice transplanters.

It is desired to improve work efficiency in rice transplanting work, and Jikaisho is an example of a structure that embodies this desire.
It is disclosed in Publication No. 60-55317. This structure is a model that speeds up the planting process by planting one row with multiple planting claws, instead of planting one row with one planting claw like normal models. The posture of the planting claws is determined by a gear mechanism inside the planting case when taking out seedlings and when planting seedlings.

In the gear mechanism, there is a breakage at the occlusal part, so when the planting claw passes through the seedling take-out port of the seedling stand and takes out the seedlings, the reaction force from the seedlings causes the planting to occur by the amount of breakage. The pawl swings backward slightly, causing a phenomenon in which the gear teeth collide with each other within the gear mechanism. Since this collision phenomenon occurs continuously during the planting operation, there is a risk that fatigue failure will develop, particularly in the occlusal portion of the gear mechanism.
ここで本発明は前述の問題に着目して、苗取出

る。
When an agricultural granular material feeding device mounted on a rice transplanter and used for fertilization or seeding is driven, a load, that is, a mechanical reaction force is also generated on the drive source side. Therefore, with the above-mentioned configuration, in the range where the planting claw plunges into the mud and rises again to reach the seedling take-out port, the reaction force acts on the planting claw connected to the agricultural granular material feeding device. , acts to rotate the planting case around its pivot point in a direction opposite to the rotational direction of the planting case. As a result, the planting claw passes through the seedling removal port in a state where at least the rocking state of play due to backlash between the gear of the planting claw and the gear that engages directly with it has disappeared. .

た。
As described above, by making some modifications to the linkage between the agricultural powder and granule feeding device and the seedling planting device, it is possible to directly engage the gear of the planting claw, which is the location where the collision phenomenon due to the play of the grass crusher is most severe. It has become possible to prevent the gear teeth from colliding with each other due to the reaction force when taking out the seedlings at the interlocking part between the mating gears, and the durability of the seedling planting device has been improved.

を通過して苗を取出すのである。 Therefore, after planting the seedlings in the field, the planting claws 3A rotate around the rear side and move up, while driving the feed-out drive section 8a upward through the link 12. At this time, the planting claw 3A receives a reaction force from the feeding drive part 8a, and this reaction force causes the planting claw 3A to rotate clockwise in FIG. 1 around the connection point with the planting case 2. It is affected like this. As a result of the above-mentioned action, the planting claw 3A is moved to the seedling take-out port 4a in a state where the play due to backlash at the interlocking part between the gear part 15a of the swing shaft 15 and the second gear 16 in FIG. 2 is eliminated.
The seedlings are taken out by passing through them.
