A seedling holder is provided to push out the seedlings to be planted toward the seedling take-out port and hold the subsequent seedlings in position, and this seedling holder is moved between the standby position and the push-out position by a four-link mechanism. This invention relates to a seedling transplanter that can be freely configured.

Description of the Related Art Conventionally, in the above-mentioned seedling transplanter, as disclosed in, for example, Japanese Unexamined Patent Publication No. 3-10609, the tip acting portion of the seedling holder is configured to be swingable. Some devices are configured such that when approaching the position where the tip acts on the seedlings, the tip acting part swings slightly downward due to the spring force of the compression spring caused by the relative movement of each link in the parallel four-link mechanism.

点を解消することを目的としている。[Problems to be Solved by the Invention] The above conventional structure pushes out the target seedlings to the seedling take-out port by the oscillating action of the tip acting part, so that the seedlings to be planted can be reliably taken out by the planting claw, and the seedlings to be planted and the following By reliably planting the seedlings separately from each other, variations in the number of plants planted are suppressed and the risk of missing plants is reduced. However, when using the above conventional structure, in addition to the parallel four-link mechanism that supports the seedling holder so that the posture can be changed freely between the retracted position and the working position, the tip working part is swung slightly downward near the working position. This had the disadvantage that a special link mechanism was required to do so, making the structure complicated, and there was room for improvement. The present invention aims to solve the above-mentioned disadvantages.

The first link is configured to be longer than the second link located therein, and in the standby position, the first link is set to have an attitude inclined toward a side away from the seedling stand rather than a vertical attitude, and The second link is set to have an attitude that is inclined toward the seedling stand rather than a vertical attitude.

る。[Operation] When the seedling holder moves from the standby position to the working position, the first link changes from an attitude tilted away from the seedling tray to an attitude tilted toward the seedling tray beyond the vertical position. , the connection point with the seedling holder, that is, the rear side of the seedling holder, undergoes relatively little vertical displacement. Then, the second link changes its posture from a vertical posture that is inclined toward the seedling tray side to an even larger inclination, so that the connection point with the seedling holder, that is, the front side of the seedling holder , the vertical displacement is large. As a result, the tip of the seedling holder supported by the first link and the second link moves downward as it moves to the operating position, effectively pushing out the roots of the seedling toward the seedling outlet. It will work.

A product with extrusion function was obtained, which made it possible to simplify the structure and improve durability.

押し出すことができる。[Example] Hereinafter, an example will be explained based on the drawings. Figure 1
The figure shows a transplanter for rice seedlings, which is an example of crop seedlings. This seedling transplanter is connected to the rear part of a traveling body (not shown) so as to be able to rise and fall freely, and the seedling platform is tilted backwards and is supported by a transmission case 2 that also serves as a frame so as to be able to move back and forth in a fixed stroke. 3. Seedling outlet 4 at the bottom of the seedling stand 3
The system includes a seedling planting mechanism 5 that takes out seedlings one by one and plants them in the field, a grounding float 6 that slides on the mud surface, and the like. The seedling table 3 is provided with a vertical feeding device 7 of an endless rotary belt type with a protrusion, and is configured to feed the placed seedlings toward the seedling take-out port 4. The seedling planting mechanism 5 includes:
The planting claw 8 attached to the tip is configured to take out seedlings one by one from the seedling take-out port 4, hold them, and plant them in the mud surface while drawing a substantially elliptical trajectory by a swinging crank mechanism 9. Then, prior to the operation of taking out the seedlings of the seedling planting mechanism 5, the seedlings to be planted are moved from the standby position toward the tip end side in the sending direction, and the seedlings to be planted are directed toward the seedling taking out port 4. A seedling holder 10 is provided for pushing out the following seedlings and holding the succeeding seedlings in position. To explain in detail, this seedling holder 10 has a pair of front and rear swing links 11a, 11
It is pivotally connected to the transmission case 2 through the transmission case 2 to form a quadruple link mechanism A, and is biased to return to the rear standby position by a spring 12, and by a cam mechanism 13 provided inside the transmission case 2. It is configured to be switched to the seedling pushing position and driven. The first link 11a located on the side far from the seedling rest 3 in the four-link mechanism A is configured to be longer than the second link 11b located on the side of the seedling rest 3, and the 1st
The posture of the link 11a is set to be inclined toward the side away from the seedling platform 3 rather than the vertical posture, and the posture of the second link 11b is set to be inclined toward the side of the seedling platform 3 rather than the vertical posture. It is set in the same position. By adopting such a non-parallel type scalene quadruple link structure, as shown in FIG. 2, as the seedling holder 10 moves from the standby position to the front side, the connection point with the first link 11a, That is, the rear side of the seedling holder 10 has little vertical displacement, and the second link 11
The connection point with b, that is, the front side of the seedling holder 10, has a large amount of vertical displacement, and as a result, its tip acting portion 10a enters the seedling row and directs the seedlings to be planted toward the seedling outlet 4. It can be pushed out.
