Description

[Detailed Description of the Invention] The present invention is characterized in that a plurality of lights (m-7m-) are biased downward in order to be parallel to each other in the lateral direction of the aircraft, in the 'Fi planting section that can be driven up and down with respect to the traveling aircraft. (rear end side axis center circumference), upper and lower 4 separately
! 1. While pausing in the state of moving, this detection result was set to 4 based on the detection result of the height of the seedling planting part of the contact @y funnel.
This invention relates to an elevating and lowering operation structure for the planting section of the Tajima machine OT1, which has a control mechanism for automatically elevating and lowering the predistribution and planting section as shown in the figure.

In the above-mentioned seedling planting part lifting/lowering operation structure, conventionally, all the grounding parts 74-F can be vertically swung separately, so that the soil leveling function of the pots and each part a-) can be fully demonstrated. In order to keep the control mechanism in place, only one of the grounding points 70 is set to the center 70, and the seedling planting section is adjusted based on the height of the seedling planting section of this center 70. It was configured to raise and lower automatically. Therefore, local unevenness that exists only in the area where the sender 70-toe is in contact with the ground can be detected! I# Aya is done and non-sen? - There was a drawback that the seedlings corresponding to the float were planted at different depths (planting depth by one device was changed unevenly, resulting in the seedlings being planted too deeply).

As an example of a means to eliminate such drawbacks, it is possible to use floats at both the left and right ends as largely independent Sen4r-floats, and to calculate the average of their detection results using appropriate means, but in this case, (A mechanism is required to average the detection results from the left and right sensor floats and transmit this to the elevation control mechanism.) This has the disadvantage that the control mechanism becomes structurally complex.

ρh%, profit? The purpose is to make it possible to construct a 14-ridge structure into a structural register, while making it difficult for the planting depth to be reduced due to local unevenness as described above.

Next, I will explain the zero*l14O* example based on the IiI garden.

According to 41), the rice transplanter can be raised and lowered freely, and seedlings can be planted from the traveling body. .

To plant seedlings in 8 rows at a time, the seedlings are planted in 8 rows at a time by swinging the seedlings up and down separately using the rear-end shaft center I) around the periphery, with each seedling being biased downward by its own weight. In addition, the rotating shaft and both arms (18 m) are configured so that they move up and down integrally with the planting area while being biased downward.

This allows work to be done while keeping the depth of the seedling planting area almost constant.

The operating lever (2) shown in the gFIs diagram is used to change and set the planting depth to be maintained by changing the distance between the actuator wire (18k) and the arm in the operating wire.

In addition, when using a rice transplanter for planting 5 rows or IIA rows with 8 ground floats arranged side by side, only the 3 ground floats located on the outside between the left and right sides, or all the ground floats can be used for seedling planting. It can also be implemented in a form in which it is connected to the planting part so as to be raised and lowered integrally with it, and the height of these grounding ya-tos relative to the planting of seedlings is detected.

In summary, the present invention provides a structure for lifting and lowering the seedling planting material part of a rice transplanter in which snow is raised.

Stable elevation control is performed with less influence from unevenness. This ensures that the ground leveling is performed reliably v4 and that the elevation control is performed accurately0*2
Therefore, we were able to provide an inexpensive product that can improve the planting speed with extremely high accuracy.
