Description

[Detailed Description of the Invention] Industrial Application Field The present invention provides a sweet potato seedling transplanter that can orderly plant sweet potato seedlings held in a transplanting body in a predetermined planting posture as the machine moves. This is related.

BACKGROUND ART Conventionally, as a transplanting machine used when transplanting sweet potato seedlings, there is a known one that uses tweezers-like clamping claws to pinch the base of the sweet potato seedling and insert it into the soil.

Problems to be Solved by the Invention In general, methods for planting sweet potato seedlings include horizontal planting in which seedlings are transplanted horizontally, boat bottom planting, diagonal planting,
There are many types of upright planting, but in particular, so-called boat-bottom planting, in which the center of the seedling is planted in a boat-like planting position, is slightly deeper.
It is widely used because it requires less planting and the seedlings take root well.

However, with conventional transplanters that simply pinch the base of the seedlings with their clamping claws and insert them into the soil, it is not possible to plant the seedlings in a boat-like shape by deepening the center of the seedlings. Since they were planted by hand in a boat-shaped shape, the transplanting work required a great deal of labor and had the disadvantage of poor work efficiency.

The present invention was devised in order to solve these problems in view of the above-mentioned actual situation, and it is possible to simply hold the sweet potato seedlings in the transplanting body while moving the machine, and by rotating the transplanting body.
