Embodiments of the present invention will be described below. First, an outline of a riding rice transplanter will be described with reference to FIG. (1) is a passenger vehicle body, and a planting portion (3) is provided at a rear portion of the passenger vehicle body (1) via a lift mechanism (2).
Are linked. The passenger body (1) has a transmission case (5) attached to the rear of the body frame (4), and has an engine (6) mounted on the body frame (4) and a front wheel (7) under the engine (6). There is also a transmission case (8) extending rearward from both left and right sides of the transmission case (5). At the rear end of the transmission case (8) is a rear wheel (9).
(10) is a driver's seat, (11) is a footrest, (12)
Is a running handle. A top link (13) and a lower link (14) are attached to the lift mechanism (2).
3) By swinging (14), the planting section (3) is moved up and down. The planting section (3) includes a seedling mounting table (15), a float (16), and a planting arm (17). The planting arm (17) is operated by the power transmitted from the transmission case (8) via the drive case (18) and the planting transmission case (19), and the planting claw (2) attached to the tip thereof.
The seedling is pinched and planted from the lower end of the seedling mounting table (15) by the loop curve movement of 0). Reference numeral (21) denotes a turning plant marker, which is rotatably attached to the front center of the vehicle body frame (4).

A conventional example of the surrounding planting marker (21) in the rice transplanter as described above will be described in more detail. That is, in FIG. 2, when the surrounding planting marker (21) is used in common with the center marker, the surrounding planting marker (21) is tilted left and right, and the tip position of the fall is set as the marking position. For this reason, the operator imagined a perpendicular (L) vertically lowered from the marking position, and since the vertical line (L) was set as the ridge position, it was inaccurate due to parallax. As a result, the distance from the ridge fluctuates, and after round planting, sparse planting or dense planting occurs, leading to a decrease in planting accuracy. In addition, since the driver must drive while imagining the position of the marking, the psychological burden on the operator is large, which has led to a reduction in work efficiency.

Therefore, in order to solve the above problems,
The present invention relates to a marker for surrounding planting (2) as shown in FIG.
1) is provided. That is, the turning plant marker (21) to be used by being tilted to the horizontal position is configured so that the tip thereof can be bent substantially vertically downward, so that the position indicated by the marker is indicated by a position closer to the ridge. Thus, an error in the distance between the operator's line of sight (A) and the actual position is reduced, and a more accurate planting position can be maintained.

Next, a specific configuration of the stepped type surrounding planting marker will be described with reference to FIG. The surrounding planting marker (21) disposed substantially in the width direction of the fuselage includes a hollow member (2).
2) A rod-shaped body (23) provided with a hollow cylindrical body (E) having a coil spring (S) incorporated therein, and a swing-out body (25) is rotated at the tip of the rod-shaped body (23) via a joint (24). The rod-like body (23) moves a predetermined distance from the hollow member (22) and reaches the tip of the hollow member (22). Is configured. By providing a weight (W) at the tip of the swinging body (25), a function of suppressing swinging when the swinging body (25) falls in the vertical direction can be provided. In addition, a rod-like body (23)
Is provided with a multi-stage hollow member so that it can expand and contract, and can be stored in the hollow member (22).

The turning plant (21) is normally housed with a swinging body (25) locked to a hollow member (22) by a detent portion (D) comprising a concave portion and a convex portion. A wire (Y) is fixed to the hollow cylindrical body (E), and one end of the wire (Y) is connected to a marker operation lever (M) of a driver's seat (10). When the swinging body (25) is used as a planting marker and the marker operating lever (M) is operated, the hollow cylindrical body (E) connected to the wire (Y) rotates while being drawn to the operator side. Then, the concave and convex engagement of the detent portion (D) which always engages the hollow member (22) and the rod-shaped body (23) is released, and the rod-shaped body (23) is urged by the coil spring (S). From the hollow member (22) to the outside. Further, by designing the marker operation lever (M) to be switchable in a plurality of stages, it becomes possible to adjust the multi-stage hollow member stepwise according to the operation. In addition, the swinging body (25) is connected to the hollow member (22).
When it is stored in the hollow member (22), the operator inserts the swinging body (25) into the hollow member (22) with his own hand and returns it to the normal position.

As an operation of the surrounding planting marker (21), a stepless adjusting means shown in FIG. 5 can be used. That is, the electric pinion (P) is installed on the inner wall of the hollow member (22), and the rack (R) meshing with the pinion is connected to the rod-shaped body (2).
By providing the driver in the driver's seat (1)
It is possible to operate the operation switch while riding on (0) and adjust the swinging body (25) to an arbitrary position according to the ridge position and swing it out. In addition, since the storage of the swing-out body (25) is performed by the reverse rotation of the electric pinion (P), there is an advantage that the operator can operate while riding on the driver's seat (10).

According to the marker for planting around the present invention having the above-mentioned structure, it usually contributes to the operator's work while standing in the center of the body as a center marker. Thus, the swing-out body can be swung out of the center marker by manual or electric operation and dropped vertically to support the position of the tip of the marker near the ridge. In addition, since the marker swing-out position can be adjusted appropriately, it is possible to cope with a change in the ridge position.

[0012]

As described above, according to the first aspect of the present invention, the marker body is lowered vertically below the mark position in the riding rice transplanter provided with the turning marker according to the present invention. Since the difference between the line of sight and the actual position is reduced and the more accurate planting position can be maintained, unnecessary dense planting and sparse planting can be avoided, and the seedlings can be planted effectively. Further, unlike the related art, the operator does not need to imagine the marking position vertically below the marker position to drive, and the psychological burden on the operator can be reduced, leading to an improvement in work efficiency.
According to the second aspect, since the rod-shaped body is stored in a retractable manner, the surrounding planting marker becomes compact. According to the third aspect, since the sheets are stored in a multi-stage manner, it is possible to appropriately cope with a change in the ridge position.
