Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a seedling supply method and a seedling supply using a transplanter that uses aligned seedlings that can be separated into individual seedlings in the transplant cultivation of agricultural crops. Regarding the device and its seedling transport container.

(Prior Art) There are various methods for transplant cultivation, and for example, a method using paper tube seedlings is widely used. This paper tube seedling method usually uses a seedling raising container in which many paper tubes are arranged in an orderly manner and separably connected using water-soluble glue, and the seedlings are raised by filling the container with soil and sowing seeds. Seedlings are separated into individual paper tube seedlings and transplanted using a seedling separation device.The seedlings can be transplanted while reliably retaining the colored soil, and paper tubes have been developed that decompose within a short period of time after transplanting, making it possible to transplant seedlings in various paper tubes. It is expected to be used in agricultural crops.

On the other hand, since the paper tubes of the paper tube seedlings mentioned above are filled with soil, the paper tube alignment surface of the seedling raising container is heavy, and the individual paper tube seedlings are connected with glue, so there is a bonding force. Since the paper tube alignment surface is weak, great care must be taken when handling this paper tube alignment surface to prevent it from separating before transplantation.
Conventionally, a seedling transport container with an opening at the top and one side was used to transport such heavy paper tubes, and in order to feed them to the transplanter, they were separated manually into rows before being fed to the transplanter. I was 1jLW on the conveyor.

There was no way to easily transfer this group of heavy paper tube alignment surfaces from the seedling transport container to the seedling feeding device of the transplanter. This is because if you simply try to push out the paper cylinder alignment surface from the seedling transport container, the friction between the paper cylinder seedlings and the seedling transport container will apply unreasonable force to the paper cylinder seedlings, causing the joints to separate or the paper cylinder to This results in deformation of the aligned plane group.

(Problems to be Solved by the Invention) Efficient transplanting work cannot be expected with the manual seedling feeding method as in the conventional technique, and the efficiency of transplanting work is dependent on the human working ability. It goes without saying that it would be more efficient if the arrayed bacterial group was transferred to the transplanter as is, and the transferer automatically separated and transplanted it.

However, in the case of a heavy paper tube alignment surface, if the paper tube seedlings are handled roughly, the weak connections between the paper tube seedlings may separate, resulting in individual seedlings before being fed to the separating section of the transplanter, or They may break up into groups of paper tube seedlings in small, irregular units.

In addition, when heavy seedlings are simply pushed out, there is a large frictional force between the bottom surface of the container and the container for transporting seedlings. The mutual spacing between the seedlings becomes incorrect, and it is impossible to accurately separate the seedlings into individual seedlings simply by using a mechanical separation unit.

Therefore, it is extremely difficult to transfer arranged seedlings that are easily separated or deformed, such as the heavy paper Fi arranged seedlings, onto the seedling supply conveyor of a transplanter without much effort. Seedlings can be separated into individual seedlings and transplanted using an automatic seedling separation device.

The purpose of the present invention is to solve the above-mentioned problems, provide a high performance and highly efficient transplanting machine, and dramatically expand transplant cultivation.

[Structure of the Invention] (Means for Solving the Problems) The seedling supply method of the invention of claim 1 is a seedling supply method in which arranged seedlings 3o are transferred from a seedling transport container 20 to a seedling supply device IO of a transplanter.
