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]

Normally, one set of planting mechanisms is provided for one seedling mounting table, and one set of seedling trays is used.
Rows of seedlings are taken out and planted, but in a walk-type transplanter that has only one seedling platform, only one row is planted in one stroke of work, and When multi-row planting is carried out, it is necessary to perform the work corresponding to the number of rows. Therefore, for example, there is a structure in which two seedlings are taken out from one seedling tray, and two seedlings are planted at the same time, and two seedlings are planted in one process. The number of pots in one stroke of horizontal feeding is, for example, 5 when 200 holes (10 horizontal × 20 vertical), and 6 when 288 holes (12 horizontal × 24 vertical). In such a case, the timing between the vertical feeding and the vertical feeding is deviated, and there is a troublesome operation that requires adjusting the timing of the vertical feeding each time according to the odd / even number of pots.

[0003]

SUMMARY OF THE INVENTION Accordingly, the present invention relates to a transplanting machine in which seedlings sequentially taken out from a seedling tray of a seedling table to be laterally fed by a seedling picking nail are transferred to a seedling mounting nail and planted. The vertical feeding means for vertically feeding the seedling tray in correspondence with the number of even and odd pots in one horizontal feeding process is provided. The feeding is synchronized to improve the seedling collecting accuracy.

Further, in a vertical feeding means provided with a vertical feeding cam for performing vertical feeding at the left and right horizontal feeding ends of the seedling tray, provided so that the phase of the vertical feeding cam is different depending on the odd number and the even number of pots. For example, in the case of an odd number of pots, among the left and right vertical feed cams that operate at the left and right horizontal feed ends of the seedling tray, the mounting phase of one side cam is changed by 180 degrees to adjust the timing to the left and right horizontal feed ends of the seedling tray. It enables vertical feeding of the seedling tray.
