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). There was a disadvantage that the work efficiency was extremely poor, for example, it was necessary to deal with short crops between the stocks.

[0003] For this reason, two seedling-planting claws having a phase difference of 180 degrees on the same locus are provided, and one set of seedlings is conventionally planted with one nail as a set, whereas the seedlings are planted within the same time. There are means to plant two strains, but if such a means is to open and close the seedling claw corresponding to the up and down planting operation, the structure becomes extremely complicated and accurate opening and closing There is an inconvenience that it becomes difficult.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention relates to a vegetable transplanting machine in which seedlings are planted by opening and closing a seedling planting claw during the vertical movement of a planting arm by rotation of a crank arm. Opening and closing the seedling planting nail by the change of the relative position between the arm and the planting arm, allowing the opening and closing position of the seedling planting nail to be easily set on the planting locus of the nail,
The opening and closing of the nails is performed in synchronization with the vertical movement of the nails with seedlings.

An opening / closing cam is fixed to the crank arm, and an opening / closing cam is connected to the opening / closing arm of the planting arm for opening and closing the seedling claw via a link, so that the seedling claw is synchronized with the rotation of the crank arm. To open and close the seedling claw by transmitting the change in the relative position between the crank arm and the planting arm to the seedling claw by simple means such as an opening / closing cam and a link, so that the seeding claw can be reliably and accurately opened and closed. is there.
