Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is designed to roll long mat seedlings.
The present invention relates to a rice transplanter for planting roll seedlings wound in a roll shape.

[0002]

2. Description of the Related Art In Japanese Utility Model Publication No. 58-11133, a roll seedling supply section (spare) in which a spare seedling in which mat seedlings are rolled is continuously fed from the outer peripheral side thereof A seedling stand) is provided, and a seedling stand on which the seedlings fed from the roll seedling supply section is placed is provided, and one plant is taken from the end of the seedling placed on the seedling stand and planted in the field. A rice transplanter equipped with a device is disclosed.

Further, Japanese Patent Publication No. 47-34605 discloses that
Rolls of seedlings cultivated in a long strip net wound in a roll
A roll seedling supply unit is constructed so that the roll seedlings are continuously fed from the outer peripheral side, and one plant is taken from the roll seedlings fed from the roll seedling supply unit and planted in the field. In a rice transplanter equipped with a device, the roll seedlings fed from the roll seedling feeding section are fed in a state in which the leaves of the seedlings are tilted in the feeding direction, and then the lying leaves are raised by a standing rod. Then, a rice transplanter configured to be supplied to the planting device is disclosed.

[0004]

In recent years, in order to improve the efficiency of rice transplanting work, a high-speed rice transplanter has been developed in which the transplanting work speed of the rice transplanter itself is increased. However, in order to further improve efficiency, it is necessary to reduce the number of times the seedlings are replenished in the rice transplanter so that the continuous planting work run without interruption can be extended as long as possible.

Therefore, a rice transplanter having a structure in which a long mat seedling is wound up in a roll and continuously rolled out and planted is one of the very effective structures for improving the efficiency of rice planting work. Attention as one. Now, in order to put the rice transplanter into practical use, the following issues emerge as important issues. That is, it is a problem that the roll seedling is a mat seedling wound as long as possible and that the roll seedling is supplied to the planting device in an appropriate posture.

[0006] Looking at the above-mentioned prior art from the viewpoint of the above problems, the rice transplanter disclosed in Japanese Utility Model Publication No. 58-11133 discloses a general 60 cm long seedling reserve seedling in a loosely wound state. Roll seedlings, which are placed on a trapezoidal roll seedling supply section, from which the roll seedlings can be fed out to a seedling placing table, and the roll seedlings are planted. Is. Therefore, in this rice transplanter, the roll seedlings are used in a state in which they are loosely wound, so that the posture of the seedlings to be fed out is not disturbed so much and proper planting is possible. However, when using roll seedlings wound with continuous long mat seedlings from the above-mentioned problem, the roll seedlings are usually wound in a state in which the seedlings are pressed against each other and the leaves fall in the feeding direction. The seedlings supplied to the device will be supplied in a state where the leaves are laid down so as to block the planting trajectory of the planting device, and the leaves will contact the planting claws first when the seedlings are separated from the planting device. The seedlings are not separated in the proper condition, and the planting in the field cannot be performed properly. Therefore, this conventional rice transplanter cannot satisfy the above problems.

Next, in the rice transplanter disclosed in Japanese Examined Patent Publication No. 47-34605, in the above-mentioned problem, although it is a roll seedling that has been wound for a long time, the seedling to be wound is a special seedling grown in a long strip. However, it cannot be easily applied to the current form of rice transplanter. Moreover, in the said subject,
Roll roll seedlings are wound in a state in which the leaves of the seedlings are collapsed in the feeding direction, and the seedlings fed in that state are raised by a separately provided standing rod and supplied to the planting device. Therefore, the posture of the seedlings supplied to the planting device is corrected by the standing rod, which seems to satisfy the problem.However, as described above, using the special seedlings grown in long strips. It is made possible by the existence of. That is, in the case of this rice transplanter, the strips are forcibly pulled out in order to feed the roll seedlings, the planting device removes only the seedlings from the strips, and then the strips are separately collected. Since it was a structure that was set up, it was possible to easily raise the leaves just by hitting the standing rod against the leaves of the seedlings. On the other hand, mat seedlings that are commonly used at the present time are planted after being separated into mat parts (seed beds) in a planting device of a rice transplanter. Therefore, in the case of mat seedlings, it is not possible to directly grab the mat part and forcibly pull it out, so that the seedlings will be sent mainly by applying a conveyor belt to the bottom of the mat part. When the standing rod is hit like this, the seedlings are lifted up and the planting device can not properly take the seedlings, or it becomes a great resistance to the transport of the seedlings and the seedlings cannot be properly sent to the planting device. The problem arises.
Therefore, in this conventional rice transplanter, a technique that can be applied to roll seedlings in which a long mat seedling is rolled is not used.

Therefore, in order to put into practical use a rice transplanter having a structure in which a long mat seedling is rolled out and planted continuously, the mat seedling as long as possible is put into practice. There is a problem in that the rolled seedlings can be used, and the rolled seedlings are supplied to the planting device in an appropriate posture.

[0009]

In order to solve the above-mentioned problems, the present invention is designed so that roll mat seedlings in which a long mat seedling is rolled are continuously fed from the outer peripheral side thereof. The roll seedling supply unit configured as described above is provided, and the seedling placement table on which the seedlings fed from the roll seedling supply unit is placed is provided, and one plant is taken from each end of the seedling placed on the seedling placement table. In a rice transplanter provided with a planting device to be planted in a field, the roll seedlings are configured to be supplied to the planting device in a state in which leaves fall in a direction away from the planting locus of the planting device. The rice transplanter is characterized by that.

[0010]

First, the roll seedling, which is a state in which long mat seedlings are rolled in a roll shape, is loaded into the roll seedling feeding section of the rice transplanter, and the loaded roll seedlings are The seedlings are continuously fed from the outer peripheral side, and the fed seedlings are placed on a seedling placing table. Then, the planting device picks up one by one from the end of the seedling placed on the seedling placing table and planted in the field. The roll seedlings supplied to the planting device here are supplied in a state in which the leaves fall down in the direction away from the planting locus of the planting device, so the leaves are not obstructed and the planting device is suitable. It works on the mat part surely and separates one plant surely and plant it in the proper posture in the field.

Therefore, even if a roll seedling wound with a mat seedling as long as possible is used, the roll seedling is supplied to the planting device in a proper posture and properly planted.
It is possible to put into practical use a rice transplanter having a structure in which a long mat seedling is rolled up and continuously rolled and planted, and the efficiency of rice planting work can be further promoted.
