Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a marker device for a transplanter, and more particularly to a mounting structure in which the depth of the marker submerged in the soil does not change when the planting depth of rice seedlings is adjusted.

[0002]

[Prior Art]

 Generally, a marker is a device that marks a position to be passed next time in the field while moving from one side of the field to the other side. Therefore, if the tip of this marker is submerged in the soil too shallow, it will be difficult to see it from the driver's seat, and if it is too deep, running resistance will unnecessarily increase, and weeds and straw debris will be easily entangled.

[0003]

[Problems to be solved by the device]

 Conventionally, the marker provided on the transplanter is pivotally attached to the work machine frame. However, in the rice planting work, it is often necessary to change the planting depth of rice seedlings depending on the field conditions. At that time, if the marker is left as it is, the depth that it sinks in the soil will change, and if it is too shallow the mark will be unclear, and if it is too deep, the marker will be deformed or Since problems such as dragging of straw waste occur, it was necessary to readjust each time.

[0004]

[Means for Solving the Problems]

 The purpose of the present invention is to solve such a problem and to provide a marker device for a transplanter having a simple structure in which the depth of immersion of a marker is automatically changed when adjusting the planting depth of rice seedlings. Therefore, a plurality of floats 2b arranged in the left-right direction are connected to the free end of the arm 2a extending rearward and downward from the connecting shaft 2 horizontally mounted on the work machine frame 1b. In the transplanter that rotates to adjust the implantation depth, a marker 2e is pivotally supported on the connecting shaft 2 and the marker 2e is advanced to the outside of the connecting shaft 2 by an operation wire 3. The work wire 3 extends rearward and downward from the connecting shaft 2 so that its tip is buried in the soil of the field, and the raising position is located above the connecting shaft 2, and the operation wire 3 is received. A portion 3d is provided on the connecting shaft 2 and configured.

[0005]

[Work]

 To change the planting depth of rice seedlings, the planting depth adjusting lever 2d is adjusted to rotate the connecting shaft 2, and the float 2b supported on the tip of the arm 2a connected to the connecting shaft 2 is moved up and down. Done by Since the marker 2e extends rearward and downward from the connecting shaft 2 substantially parallel to the arm 2a supporting the float 2b, when the connecting shaft 2 is rotated, the marker 2e is displaced by the same amount as the displacement of the float 2b. Is given.

Furthermore, since the posture of the marker 2e is switched by the operation wire 3 supported by the receiving portion 3d provided on the connecting shaft 2, the posture of the marker 2e is not affected even by the rotation of the connecting shaft 2.

A drive case 1c extending in the left-right direction is swingably connected in the left-right direction by a pivot 1d supported by a bearing facing the front-rear direction at the center of the working machine frame 1b. The drive case 1c is connected to a seedling stand 1e that supports the lower end of the mat seedling with an apron and moves back and forth in the left-right direction, and a chain case 1h that drives a planting unit 1f having a planting claw. ing. Below the drive case 1c, a connecting shaft 2 is rotatably supported via a substantially triangular bracket 1j.

The connecting shaft 2 is made of a steel pipe, and a large number of arms 2a extend rearward and downward from the outer surface of the connecting shaft 2. A float 2b is rotatably attached to the tip of the arm 2a by a pin 2c. There is. The arm 2a is provided with a planting depth adjusting lever 2d that extends upward from the connecting shaft 2 and is operated from the driver's seat, and left and right markers 2e that mark the position of the return path in the field.

As shown in FIG. 4, the connecting shaft 2 is welded with an auxiliary pipe 4e extending upward from the shaft end, and the root of the marker 2e is attached to the outer end of the auxiliary pipe 4e by a pin 2f constituting a pivotal support. The operation wire 3 has an extension 3a that is rotatably pivotally supported and locked to the root so that it can be undulated between a working posture shown in the figure and a retracted posture shown by an imaginary line. A support plate 3d for supporting the outer pipe of the operation wire 5c is provided above the auxiliary pipe 2e, and hooks 3e for locking the marker 2e at the storage position are welded near the support plate 3d. And it is adapted to rotate with the marker 5.

Since this marker device is configured as described above, the planting depth adjusting lever 2d is operated from the initial state in which the planting depth adjusting lever 2d and the float 2b are in the positions shown by the two-dot chain line in FIG. When the connecting shaft 2 is moved to the solid line position, the connecting shaft 2 is rotated in the clockwise direction by a slight amount, and the float 2b is also moved to the solid line position accordingly. That is, as the planting depth becomes a little shallower by operating the planting depth adjusting lever 2d, in the conventional case, the marker 5 is lifted from the surface of the field, and the line is not marked on the field or is thin. Tended to be. However, in this embodiment, the depth of the marker 2e, which is rotated in the clockwise direction together with the connecting shaft 2 along with the float 2b, is increased so that the marker 2e is immersed in the soil. Further, since the rotation of the connecting shaft 4 also rotates the hook 3e for locking the marker 2e, the marker 2e can be locked at the storage position without any trouble when the marker 2e is stored. it can.

[Effect of the device]

 A marker device for a transplanter according to the present invention connects a plurality of floats 2b arranged in the left-right direction to a free end of an arm 2a extending downwardly rearward of a connecting shaft 2 horizontally mounted on a working machine frame 1b. In a transplanter that rotates the connecting shaft 2 to adjust the planting depth, a marker 2e is rotatably supported on the connecting shaft 2, and the marker 2e is connected to the connecting shaft 2 by an operating wire 3. In addition to advancing outward and extending rearward and downward from the connecting shaft 2, the working posture in which the tip of the connecting shaft 2 is buried in the soil in the field and the raising posture positioned above the connecting shaft 2 are performed. The receiving portion 3d of the operation wire 3 is provided on the connecting shaft 2.

Therefore, if the float 2b descends downward, the tip of the marker 2d will also be deeper immersed in the soil, so that it is not necessary to adjust the burial amount of the marker 2d each time, even if the planting depth is changed. This has the effect of simplifying the operation. Further, since the operation tool for changing the posture of the marker 2e is composed of the operation wire 3 and the outer receiving portion 3d of the operation wire 3 is fixedly mounted on the connecting shaft 2, it is necessary to adjust the planting depth. There is also an effect that the rotation of the connecting shaft 2 does not affect the posture of the marker 2d.
