Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a seedling stand for a transplanter that plants strip-shaped seedlings such as rush seedlings in a field.

[Prior art and problems to be solved by the present invention] Conventionally,
As shown in Japanese Unexamined Utility Model Publication No. 2-26413, it is known that tape-shaped seedlings on a winding drum supported on a drum bracket are brought into their summer appearance from a horizontal position to an upright position using a seedling guide. This method lacks reliability because the summer figure means to the upright position is just a guide, and there are problems such as the risk of tape-shaped seedlings scattering when planting in strong winds. When replenishing tape-shaped seedlings, it is desirable to supply subsequent tape-shaped seedlings in succession to the preceding tape-shaped seedlings, but it is necessary to stop the machine when setting or replacing the winding drum on the drum bracket. Furthermore, it was difficult to connect the preceding tape-shaped seedlings and the following tape-shaped seedlings, making the replenishment work complicated and having poor workability.

[Means to solve the problem]

In view of the above-mentioned circumstances, the present invention was devised for the purpose of providing a seedling stand structure for planting seedlings in order to solve the problems. Upright planting involves planting seedlings. Planting involves a seedling loading stand that sends out the seedlings toward the body, a horizontal conveying and feeding section that sequentially sends the strip-shaped seedlings in a horizontal position, and a clamping state that shifts the strip-shaped seedlings from the horizontal position to the upright position. a cutting device that cuts the strip-shaped seedlings sent by the upright-transforming conveyor into seedlings; and a cutting device that plants the cut seedlings into seedlings. The present invention is characterized in that it is configured by providing the following.

[Action of the invention]

According to the present invention, the continuous strip-shaped seedlings are sequentially fed in a horizontal posture by the horizontal conveyance feeding section on the upper side of the seedling table, while the root side is prevented from floating up by the seedling holding body, and will be taken over.

The inherited strip-shaped seedlings are held by the upright changing conveyance section and are conveyed from the horizontal position to the upright position, taking on their summer appearance, and then being sent to the terminal end of the seedling platform. Then, the seedlings are cut at a cutting part provided at the end of the seedling platform, and the seedlings are planted into a block of seedlings, which are then planted into the field by the body of the seedlings.
