Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vegetable transplanting machine which takes out a single plant from a seedling tray such as onion, leaf onion, white leek and the like, and plant it in a field.

[0002]

Conventionally, there is no transplant structure in which such a long vegetable seedling as an onion or the like is taken out by a claw for taking out a seedling, transferred to a claw with a seedling, and planted in a field. When removing one seedling from the seedling tray with the seedling removal nail, there was a disadvantage that the stem and leaves of the seedling were entangled with the nail and the stem and leaves were bent, resulting in poor succession to the seedling with the seedling. .

[0003]

SUMMARY OF THE INVENTION Accordingly, the present invention relates to a vegetable transplanter in which seedlings are taken out from a seedling tray of a seedling mounting table by means of a seedling removal claw and planted, and the foliage of the seedlings near the position where the seedling is taken out of the seedling tray. The part is separated from the seedling removal claw by providing a seedling control member capable of adjusting the mounting height, and when taking out seedlings from the seedling tray by the seedling removal claw, the stems and leaves of the seedlings are kept away from the seedling removal claw by the control member, and the nail is removed. The present invention is intended to prevent inconvenience of entanglement with the seedlings, to enable good succession of the seedlings to the seedling-planting nails, and to carry out high-precision transplantation without occurrence of lack of stock and the like.

Further, a plurality of seedling regulating members are provided along the upper part of the seedling mounting table, and the regulating members regulate the first stage seedling from which the seedlings are collected and the stems and leaves of the second and higher stage seedlings. Therefore, it is possible to prevent the inconvenience of the seedlings of the second and higher seedlings from being entangled with the stems and leaves of the seedlings from which the seedlings are collected, and to prevent the seedlings from falling out of the seedling extraction nails, thereby improving the extraction accuracy of the seedlings.
