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 one seedling of vegetable seedlings such as onion, leaf onion and white onion from a seedling tray and plant it in a field.

[0002]

Conventionally, seedlings taken out from a seedling tray of a seedling mounting stand by one seedling take-out claw are inherited by one seedling-planting claw to plant one seedling. Since the working speed of these claws is limited and cannot be increased, in the case of crops such as onions that are short between planted plants (8 to 10 cm), the vehicle speed is reduced (for example, about 0.2 m / s). Although the system was adapted to crops that were short between stockings, the work efficiency was extremely poor.

[0003] In addition, planting strips such as onions (20)
In the case of a crop having a small size (less than 1 cm), the driving mechanism for the left and right planting claws is also complicated, and it is necessary to reduce the size of the driving structure by making the left and right seedling planting claws have the same phase driving configuration.

[0004]

Accordingly, the present invention comprises a left and right rotary case that rotates about a central drive shaft, and a claw support rod that supports a plurality of seedling planting claws for multi-row planting. Seedlings in a multiple-row planting structure in which the connecting structure between the rotary case and the seedling planting claws is simplified by connecting and supporting the seedling-growing claws to the crank arm of the rotary case via a claw support rod. This facilitates the compactness of the drive mechanism of the planting claw.

[0005] In addition, the front claw body of the seedling-mounted claw is attached to the crank arm of the rotary case on one of the left and right sides via the front claw support rod.
The rear claw body of the seedling-mounted claw is connected and supported via the rear claw support rod to the crank arm of the other rotary case, respectively.
A plurality of seedlings for multiple seedlings are easily attached to a nail support rod disposed between the left and right rotary cases, and the mounting structure of the seedlings for multiple seedlings is reduced in size.

Further, the other end sides of the front nail support rod and the rear nail support rod are connected to each other by a connecting member, and the other end sides of the front and rear nail supporting rods are reinforced by the connecting member, so that the seedlings can be planted. The purpose of the present invention is to reduce the size of the supporting structure of the nail and to increase the supporting strength.
