Description of the Related Art In the above-described seedling transplanter, conventionally, as disclosed in, for example, Japanese Patent Application Laid-Open No. 3-10609, the tip working portion of a seedling holding tool is configured to be swingable, and this tip working portion is provided. There has been a configuration in which the distal end working portion slightly swings downward due to the spring force of the compression spring caused by the relative movement of each link in the parallel quadruple link mechanism when approaching the action position on the seedling.

欠点があり、改善の余地があった。本発明は上記不具合
点を解消することを目的としている。According to the above-mentioned conventional structure, the seedling to be planted is pushed out to the seedling take-out opening by the swinging action of the tip working portion, so that the seedling to be planted can be reliably taken out by the planting claw. By reliably separating and planting the seedlings, variation in the number of planted plants is suppressed, and the risk of lack of plants is reduced. However, according to the conventional structure, apart from the parallel quadruple link mechanism that supports the posture of the seedling holding device so as to be freely switchable between the retracted position and the operating position, the tip operating portion is slightly swung downward near the operating position. There is a drawback that a special link mechanism is required to make the structure complicated, and there is a room for improvement. An object of the present invention is to eliminate the above disadvantages.

Prior to the seedling removal operation of the seedling planting mechanism, the seedling holding mechanism moves from the standby position toward the seedling on the tip side in the sending direction, pushes out the seedling to be planted toward the seedling removal opening, and holds the position of the subsequent seedling. In a seedling transplanter that is configured to be movable between a standby position and the pushing action position by a four-link mechanism, the seedling holding tool is provided on a side far from the seedling rest in the four-link mechanism. The first link that is located is configured to be longer than the second link that is located on the side of the seedling rest, and in the standby position, the upper end of the first link is positioned more vertically than in the vertical attitude. The attitude of the second link is set so as to be inclined to a side away from the seedling rest, and the upper end of the second link is closer to the seedling rest than a parallel line with respect to the first link. Wherein configuration that is set to the inclined posture as.

出す作用が働くことになる。When the seedling holder is moved from the standby position to the operation position, the first link is tilted from the standby position in which the upper end thereof is inclined away from the seedling mounting stage to the seedling mounting position beyond the vertical position. Therefore, the connection point with the seedling holding tool, that is, the rear side of the seedling holding tool, has a relatively small vertical displacement. Then, the second link further extends from a standby position in which the upper end side is closer to the seedling stand side than a parallel line to the first link, that is, a straight line parallel to a straight line connecting the shaft fulcrums at both ends of the first link. The posture changes in a state approaching the seedling rest side, and the ratio of change in the inclination angle of the second link is larger than that of the first link due to the relationship of the lengths of the two links. That is, the front side of the seedling holder has a large vertical displacement. As a result, the seedling holding device supported by the first link and the second link moves downward toward the tip end as it moves to the operation position, so that the roots of the seedlings are directed toward the seedling outlet. The effect of pushing out works effectively.

た。Therefore, the quadruple link mechanism for switching the seedling holding tool between the standby position and the operating position is rationally improved, so that the seedling can be used without using any other special link mechanism. Thus, a structure having an extruding function was obtained, the structure could be simplified, and the durability was improved.

Fig. 1 shows a transplanter for rush seedlings, which is an example of crop seedlings. The seedling transplanter is connected to a rear part of a traveling machine (not shown) so as to be able to move up and down, and is mounted on the transmission case 2 serving as a frame so as to be reciprocally traversable at a constant stroke. 3. A seedling outlet 4 at the lower end of the seedling holder 3.
And a seedling planting mechanism 5 for taking out seedlings one by one from a plant and planting it in a field, a ground contact float 6 sliding on a mud surface, and the like. The seedling stand 3 is provided with a vertical feeding device 7 of an endless rotating belt type with a projection so as to feed the placed seedlings toward the seedling take-out opening 4. The seedling planting mechanism 5 includes:
The planting claw 8 attached to the tip is configured to take out and hold seedlings one by one from the seedling takeout port 4 and plant them in the mud surface while drawing a substantially elliptical locus by the swinging crank mechanism 9. Then, prior to the seedling removal operation of the seedling planting mechanism 5, the seedlings are moved from the standby position to the seedlings on the tip side in the feeding direction, and the seedlings to be planted are directed toward the seedling outlet 4. A seedling holding device 10 for pushing out and holding the subsequent seedling is provided. More specifically, the seedling holding tool 10 includes a pair of front and rear swing links 11a, 11a.
b, a four-link mechanism A is pivotally connected to the transmission case 2 so as to return to a standby position on the rear side by a spring 12 and to be urged by a cam mechanism 13 provided in the transmission case 2. It is configured to switch and drive to the seedling pushing action position. In the quadruple link mechanism A, the first link 11a located on the side far from the seedling rest 3 is configured to be longer than the second link 11b located on the seedling rest 3 side. First
The posture of the link 11a is more than the vertical posture of the first link 1
The upper end of 1a is set so as to be inclined toward the side away from the seedling rest 3, and the second link 11b is set.
Is set to be inclined such that the upper end side from the parallel line with respect to the first link 11a approaches the seedling stand 3 side. By adopting such a non-parallel type unequal quadruple link structure, as shown in FIG.
As 0 moves forward from the standby position, the connection point with the first link 11a, that is, the rear side of the seedling holding tool 10, has little vertical displacement, and the connection point with the second link 11b, that is, the seedling holding tool. The front side of 10 has a large amount of vertical displacement, and as a result, its distal end working portion 10a can enter the seedling row and push out the seedling to be planted toward the seedling outlet 4.
