DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a planting portion structure of a rush transplanter, and more particularly to a technique for removing seedlings well without interference of a planting claw with a seedling mounting table.

[0002]

2. Description of the Related Art The planting portion of a rush transplanter is disclosed in Japanese Utility Model Laid-Open No. 5-13.
No. 117, a plurality of standby spaces which are one step lower than the seedling mounting surface and are laterally separated by a large number of partition walls are juxtaposed at the lower end of the seedling mounting table. Regardless of the intermittent lateral feed movement, the rush seedlings, which are rose seedlings, are present at the seedling take-out portion of the guide rail so that the seedlings can be planted reliably.

[0003]

In the above publication, the width between the partition walls is wider than the lateral width of the seedling take-out port, which is a fixed system, and the planting claw is formed by the lateral play of the seedling mounting table. To prevent interference with the partition wall. In other words, from the viewpoint that the remaining seedlings after the seedling removal operation by the planting nails are not left in the standby space, it is preferable to make the width between the partition walls as close as possible to the width of the seedling removal opening, but in practice, the interference prevention described above is effective. Therefore, the width of the waiting space is slightly larger than that of the seedling outlet.

However, if only the lateral feed play of the seedling mounting table is absorbed by the accumulation of errors in the drive mechanism such as the backlash of the gears and the play of the interlocking connection, there is a large margin in the standby space, and there is room for improvement. It seems like. An object of the present invention is to make the width between partition walls closer to the lateral width of the seedling outlet in order to further reduce the remaining seedlings in the standby space after the seedling collection.

[0005]

In order to achieve the above object, according to the present invention, a take-out opening for taking out a seedling into which a planting claw can enter is formed on a guide rail which supports a seedling mounting table so as to be able to reciprocate and traverse. Then, at the lower end of the seedling mounting table, one step lower than the seedling mounting surface,
In addition, a take-out width portion, which is divided into a plurality of pieces in the lateral direction at a predetermined pitch by a plurality of partition walls, and the seedling mounting width of one row of the seedling mounting table is set at a predetermined pitch.
In addition to being arranged side by side, the lateral width of the take-out width portion is set to be wider than the lateral width of the take-out opening, and to be set so as to expand upward.

[0006]

In other words, since the width of the take-out width portion, which is the standby space, is widened upward, when the planting claw enters the standby space, there is a sufficient lateral gap to avoid interference with the partition wall. , because they narrowed standby space width when grab further intruding to rose plants, it is possible to grab a rather rose seedling leaves as much as possible grasp. In the conventional means, interference with the planting claws is inevitable when the width between the partition walls is reduced, but in the present application, the contact between the planting claws and the side surfaces of the partition walls is allowed from the functional aspect of the planting operation. As a result, the width of the standby space can be substantially reduced without interference between the planting claws and the partition wall, and can be made closer to the width of the seedling outlet of the guide rail.

Further, despite the fact that the width of the take-out width portion is made larger than the width of the seedling take-out port as in the prior art,
In the case where there is a possibility of interference between the planting claw and the partition wall, the above-mentioned upper spreading structure serves as a means for eliminating the possibility of interference without changing the standby space width.

[0008]

Therefore, the simple width of the lower end of the seedling placing table between the partition walls can be increased so that the width of the standby space can be reduced while the planting claws can be driven without interference with the partition walls. A more useful planting part for rush can be provided, which can be made substantially narrower to reduce the number of remaining seedlings, or eliminate the possibility of interference with planting claws without changing the width. Also, by reducing the intermittent lateral feed stroke of the seedling mounting table by narrowing the standby space width, it is possible to increase the number of times of planting operation during one-way lateral feed movement, thereby contributing to the enhancement of the function of the planting device. Benefits can also be expected.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 6 shows a rush transplanter, and FIG. 5 shows a planting portion thereof . 1 is a feed case, 2 is a planting case, and 3 is a planting device. The planting apparatus 3 is provided with a seedling mounting table 4 that reciprocates and moves laterally with a constant stroke, a planting mechanism 5 for extracting and planting seedlings one by one from the lower end of the seedling mounting table 4, a grounding float 6, and the like. ing. The planting arm 7 provided in the planting mechanism 5 includes a split claw-shaped planting claw 9 having a gripping groove 8 for holding the seedling, and a groove 8 for grasping the seedling held by the planting claw 9. And a seedling extruder 10 for extruding the seedling.

The seedling mounting table 4 is mounted on and supported by the guide rail 11 so as to be able to be moved laterally, and is reciprocally moved laterally by an intermittent transverse feeding mechanism (not shown) having a known structure. 1 and 2
As shown in (1), a take-out opening 12 for taking out seedlings into which the planting claws 9 can enter is formed in the guide rail 11, and at the lower end of the seedling placing stand 4 between the vertical walls 13 partitioning each line. A large number of partition walls 14 are provided to divide one seedling mounting width into a plurality of standby spaces S (corresponding to a take-out width portion) in a lateral direction at a predetermined pitch. The upper end of the partition wall 14 is pointed in a triangular pyramid shape so that the width of the standby space S is widened upward, and the width Ws of the vertical wall portion is taken out from the outlet 1.
