Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant for transplanting crop seedlings such as straw grass seedlings. More specifically, a plurality of crop seedlings are placed on a seedling stand and the crop seedlings are directed to the seedling take-out port. The present invention relates to a seedling transplanter provided with a planting mechanism that sends out a crop seedling that has been sent out, holds and plants it.

[0002]

2. Description of the Related Art In the above-mentioned seedling transplanter, conventionally, as disclosed in, for example, Japanese Patent Application Laid-Open No. 3-83506, near the seedling take-out port, behind the seedling stand and prior to the operation of the planting claws. There was a structure in which a seedling holder was provided to enter the seedlings that had been sent up to and push them out toward the seedling take-out port.

[0003]

SUMMARY OF THE INVENTION The conventional structure described above is intended to ensure that planting can be performed by holding the strawberries seedlings divided into individual plants one by one by the planting claws. However, in the above-mentioned conventional structure, the seedling holder is to push out only the seedlings to be planted by entering the seedlings from the rear side of the seedling stand, so that the seedlings to be planted are not separated from the succeeding seedlings on the upper side. There is still a room for improvement because there is a possibility that the planting claws may drag the subsequent seedlings and the number of planted plants may vary, which is not sufficient. The present invention aims to solve the above-mentioned problems.

[0004]

[Means for Solving the Problems] A feature of the present invention is that, in the seedling transplanter described at the beginning, the seedling is introduced into the seedling prior to the seedling take-out operation of the planting mechanism, and the seedling to be planted and the succeeding seedlings. And a seedling holder that separates and holds the seedling holder, and this seedling holder includes a holding claw that enters the succeeding seedling almost linearly and holds the seedling, and a lower part of the holding claw that is longer than the holding claw. The present invention is configured so as to include a push-out tool that is provided so as to protrude and pushes out the seedling to be planted toward the seedling take-out port.

[0005]

[Function] Prior to the operation of taking out the seedlings by the planting mechanism, the holding claws penetrate substantially linearly between the seedlings to be planted and the succeeding seedlings to hold the succeeding seedlings. And at about the same time,
An extrusion tool that protrudes longer than the holding claws pierces the seedling to be planted, and pushes it out toward the seedling take-out port.

[0006]

[Effects of the Invention] Therefore, the seedlings to be planted and the succeeding seedlings are reliably separated, and the seedlings to be planted are reliably pushed toward the seedling take-out port by the piercing pusher. , The operation of planting seedlings by the planting mechanism and the operation of planting in the field have no fear of stock loss, and it can be done smoothly with little variation in the number of planted plants.

Embodiments will be described below with reference to the drawings. Figure 5
Shows a straw plant transplanter. A transmission case 2 that also serves as a frame and is connected to a traveling machine body (not shown) via a link mechanism 1.
The seedling stand 3 which moves laterally back and forth with a constant stroke
The seedling stand 3 is placed on the seedling stand 3 and placed on the seedling stand 3 by the endless rotary belt type vertical feed device 4 provided on the seedling stand 3. The seedlings are sent out to the seedling take-out port 5 formed at the lower end. Arrange the planting mechanism 6 on the rear side of the seedling stand 3,
The planting mechanism 6 is configured to take out and hold the seedlings one by one from the seedling take-out port 5 and plant them in the field.

On the lateral outer side of the traveling machine body, there is provided a line drawing marker 23 for drawing a line on the mud surface, which is a guideline for the next planting run, and this line drawing marker 23 extends from the center of the machine body to the line drawing position. It is configured so that the distance can be changed and adjusted. That is, as shown in FIG. 2, the support bracket 26 is connected to the tip end portion of the support arm 24 extending laterally outward from the machine body frame (not shown) via the shock absorbing spring 25, and the support bracket 26 is connected. Further, a wire drawing marker 23 is attached via a friction holding mechanism 27 which is rotatable and positionally fixable around the longitudinal axis of the machine body. In the case of planting strawberries, it is necessary to configure in this way as shown in FIG.
This is because it is necessary to open a working space S for driving in the piles K that support the nets for aligning the falling directions uniformly for each predetermined number of rows, as shown in FIG. It should be noted that, instead of such a rotary adjustment structure, as shown in FIG.
The intermediate part of 4 may be slidably fixed by the ball detent mechanism 28.

[0009] Then, the crop seedlings fed near the seedling take-out port 5 can be changed in posture between the working position where the crop seedlings enter from above and separate left and right for each plant, and the position where they retract upward. In synchronism with the operation of the attachment mechanism 6, a rake-shaped seedling partitioning device 7 that switches between the operating position and the retracted position is provided, and the seedlings are introduced into the seedlings prior to the seedling taking-out operation of the planting mechanism 6 for planting. The seedling holder 8 for separating and holding the target seedling and the succeeding seedling is provided, and the seedling holder 8 holds the nail 29 for substantially linearly entering the succeeding seedling and holding it, and the holding nail 29. And a push-out tool 30 for pushing out the seedlings to be planted toward the seedling take-out port 5 on the lower side of the holding claw 29.

More specifically, as shown in FIG. 1, a pair of left and right swings pivotally supported by a support shaft 11 erected over the upper portion of a vertical frame 10 standing on each partition 9 of the seedling stand 3. The seedling partitioning device 7 is pivotally supported on the arm 12, and the long hole 13 formed in the vertical direction of the vertical frame 10 is engaged with the pin 14 to support the vertical movement of the planting device 6 so as to be slid vertically. The wire 16 is linked to the seedling holder 8 via the link mechanism 15 so as to move up and down between the working position and the upper retracted position in conjunction with the operation. This seedling partitioning device 7 separates from above the roots of the seedlings that have been sent to the vicinity of the seedling take-out port 5 and acts to separate them laterally, while aligning the seedlings to be planted with the seedling take-out port 5. It also acts to do.

The seedling holder 8 is provided in the transmission case 2 in a parallel four-link structure by a pair of front and rear swing links 17 and 18 and an upper link link 19, and the base end portion of the front swing link 17 is provided. The cam follower 21 is attached to the drive arm 20 continuously provided to the plant, and the cam member 23 provided on the drive shaft 22 of the planting mechanism 6 causes the holding claw 29 at the tip to enter the seedling in synchronization with the operation of the planting mechanism 6. It is configured to reciprocate back and forth to enter the seedling substantially linearly between the working position and the rearward retracted position. A supporting case 31 that supports the holding claw 29 supports an extruding tool 30 that is provided below the holding claw 29 and is made of a thin wire rod so as to be relatively swingable around a horizontal axis X. Is relatively lower side when the whole seedling holder 8 moves toward the seedling stand 3 side,
That is, the cam mechanism 32 that swings toward the seedling take-out port 5 side is provided. That is, one end of the balance arm 33 that swings integrally with the push-out tool 30 is urged by the spring 34 to swing, and the other end contacts the cam portion 35 provided on the front swing link 17. The position is regulated. When the swing link 17 swings forward, the other end of the balance arm 33 is pushed up by the cam portion 35 due to the relative swing between the swing link 17 and the link link 19, and the tip end portion of the push-out tool 30 moves. It swings downward.

According to this structure, the holding claws 29 enter between the seedlings to be planted and the succeeding seedlings to effectively hold the succeeding seedlings, and as described above, the pushing tool 30.
Is longer than the holding claw 29 and is made of a wire material, so it pierces the seedling to be planted and is reliably separated from the succeeding seedling,
Moreover, the seedlings to be planted are pushed out toward the seedling take-out opening without any omission.

It should be noted that reference numerals are added to the claims for facilitating the comparison with the drawings, but the present invention is not limited to the configuration of the accompanying drawings by the entry.
