Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a marker device for a transplanter, and in particular, when adjusting the planting depth of rice seedlings, the depth of the marker submerged in the soil is not changed. It relates to the mounting structure.

[0002]

2. Description of the Related Art In general, a marker is an apparatus for writing a position to be passed next time on a field while the marker moves from one side of the field to the other side. Therefore, if the depth at which the tip of this marker sinks into the soil is too shallow, it is difficult to see from the driver's seat.

[0003]

Conventionally, a marker provided on a transplanter has been pivotally attached to a working machine frame. However, in rice transplanting work, it is often necessary to change the planting depth of rice seedlings depending on the condition of the field. If you leave the marker at that time, the depth of submersion in the soil changes, and if it is too shallow the mark will be unclear,
On the other hand, if it is too deep, problems such as deformation of the marker and dragging of the straw waste by the marker occur, so that it is necessary to readjust each time.

[0004]

SUMMARY OF THE INVENTION The present invention solves such a problem and, when adjusting the planting depth of rice seedlings, has a structure in which the depth of the marker immersed in the soil does not fluctuate. The purpose of the present invention is to provide a marker device for a machine, in which a connecting shaft 2 is laid across a working machine frame 1b, and the connecting shaft 2 is rotated to adjust a planting depth. Machine extends rearward and downward from the connection shaft 2 and
A float 2b is attached to the tip of an arm 2a that swings with rotation.
Pivots, and in its working position, the marker 2e
And swings with the rotation of the connecting shaft 2
Marker 2 so that its tip is buried in the soil of the field.
e is attached to the connecting shaft 2 and the marker 2
e by operating the operation wire 3 connected to the marker 2
e so as to be rotatable to a raised position located above the connection shaft 2.
The receiving portion 3 d for supporting the operation wire 3 is provided on the connecting shaft 2.

[0005]

In order to change the planting depth of rice seedlings, the connection shaft 2 is rotated by adjusting the planting depth adjustment lever 2d, and the float 2b supported by the tip of the arm 2a connected to the connection shaft 2 is moved. It is performed by raising and lowering. Since the marker 2e extends rearward and downward from the connecting shaft 2 almost in parallel with the arm 2a supporting the float 2b, when the connecting shaft 2 rotates, the marker 2e also gives a displacement of substantially the same amount as the displacement of the float 2b. Can be

Further, since the position of the marker 2e is switched by the operation wire 3 supported by the receiving portion 3d provided on the connecting shaft 2, the turning of the connecting shaft 2 does not affect the position of the marker 2e.

[Embodiment] The present invention will be described below with reference to the illustrated embodiment. In FIG. 1, reference numeral 1 denotes a transplanter supported via a link mechanism 1a at a rear portion of a traveling machine body T constituting a riding type rice transplanter. C is a tracking pole attached to the front of the traveling machine T, and is used as a reference for the driver to match the field line marked by the marker 2e with the course of the traveling machine T in the previous process.

As shown in FIGS. 2 and 3, the planting machine 1
It has a working machine frame 1b coupled to a link mechanism 1a movably provided at the rear of the traveling machine body T, and has a drive case 1c extending in the left-right direction at the center of the working machine frame 1b in the front-rear direction. Are pivotably connected in the left-right direction by a pivot 1d supported by a bearing directed toward. The drive case 1c supports the lower end of the mat seedling with an apron and reciprocates in the left-right direction, and a seedling stand 1e, and a chain case 1h for driving a planting unit 1f having planting claws.
And are connected. A connection shaft 2 is rotatably supported below the drive case 1c via a substantially triangular bracket 1j.

The connecting shaft 2 is made of a steel pipe, and has a number of arms 2a extending rearward and downward from the outer surface thereof. A float 2b is rotatably attached to a tip of the arm 2a by a pin 2c. . The arm 2a has a planting depth adjusting lever 2 extending upward from the connecting shaft 2 and operated from the driver's seat.
d and left and right markers 2e indicating the position of the return trip in the field.

As shown in FIG. 4, an auxiliary pipe 4e extending upward from the shaft end is welded to the connecting shaft 2, and the root of the marker 2e forms a pivotal support at the outer end of the auxiliary pipe 4e.
f is pivotally supported by a working posture shown by locked operation <br/> extension 3a of the wire-3 to the root portion, is configured to be raised and lowered between a cause position shown in phantom I have.
It supports the outer tube of the operation wire-3 above the auxiliary pipes 4e
A receiving portion 3d is provided, and hooks 3e for locking the marker 2e at the storage position are welded to the vicinity of the receiving portion 3d, and rotate with the marker 2e .

Since the marker device is configured as described above, the operator operates the planting depth adjusting lever 2d from the initial state where the planting depth adjusting lever 2d and the float 2b are at the positions indicated by the two-dot chain line in FIG. When the connecting shaft 2 is moved to the solid line position by a small amount in the clockwise direction, the float 2b is also moved to the solid line position. That is, as the planting depth becomes slightly shallower by the operation of the planting depth adjusting lever 2d, if the plant is the conventional one, the marker 2e rises from the surface of the field, and no line is marked on the field.
Or it tended to be thin. However, in this embodiment, the marker 2e also rotates clockwise with the connecting shaft 2 along the up and down of the float 2b to increase the depth of sinking into the soil, so that the same depth as at the beginning can be maintained. Further, since the rotation of the connecting shaft 2 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.
