Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transplanter which takes out one seedling of vegetable seedlings such as onions from a seedling tray and transplants the seedlings in a field. About the machine.

[0002]

Conventionally, in a transplanter structure having one set of planting mechanisms for one seedling platform and one walking platform with one seedling platform, it takes one stroke operation. When only one row is planted, for example, when multiple rows are planted on one ridge, it is necessary to perform a work corresponding to the number of rows.

[0003]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a transplanting machine in which seedlings picked up from a seedling tray of a seedling mounting table by a seedling picking nail are inherited and planted in a seedling mounting nail. Two sets of seedling removal claws for simultaneous removal of seedlings are provided, and the mounting positions of the seedling removal claws are provided so that they can be adjusted to the left and right. By reducing the overall width, the structure is reduced and the manufacturing cost is reduced.Also, even if the number of pot holes varies depending on the type of seedling tray, the seedling removal claws are adjusted appropriately to the pot holes at the removal position. Thus, it is intended to improve the accuracy of taking out seedlings by the seedling taking-out nails.

Further, a claw set gauge for adjusting the mounting position of two sets of seedling picking nails corresponding to the type of seedling tray is provided, and the position of the seedling picking nails is adjusted appropriately and easily in a predetermined pot hole of the tray. In addition, the accuracy of taking out seedlings is improved by accurately relating the relative positions of the tray and the seedling taking-out nails.

Since the position can be adjusted left and right freely, the seedling table (2
By reducing the lateral feeding amount of 1) as compared with the conventional method, the entire width of the seedling supply device (16) can be reduced, so that the structure can be made compact and the manufacturing cost can be reduced, and the seedling tray (22) can be reduced. Even if the number of pot holes changes depending on the kind, the seedling extraction nail (23) is appropriately adjusted to correspond to the pot hole at the extraction position, and the extraction accuracy of the seedling (N) by the seedling extraction nail (23) is improved. Can be done.

Further, since a claw set gauge (78) for adjusting the mounting position of the two sets of seedling picking claws (23) is provided in accordance with the type of the seedling tray (22), a predetermined pot hole in the tray is provided. The position of the seedling extraction nail (23) can be adjusted appropriately and easily, and the relative position between the tray and the seedling extraction nail (23) can be accurately adjusted to improve the extraction accuracy of the seedling.
