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. Although there is a means for planting two plants, there is a disadvantage that the structure becomes extremely complicated when obtaining a multiple-row planting structure.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a vegetable transplanting machine for planting a single row of seedlings with two sets of seedlings having different phases by 180 degrees on the same locus. Left and right planting arms are arranged on both left and right sides of the planting drive case linked to the mission case, and the planting drive case and one set of planting drive cases are provided as one set of seedling planting claws attached to these left and right planting arms. The left and right planting arms with the claws form a single-row planting unit, and the single-row planting unit is provided in an independent state to facilitate adjustment, maintenance and inspection. This enables a plurality of planting units to be connected to each other accurately, thereby easily forming a multi-row planting portion adapted between various planting lines.

[0005] A plurality of single-row planting units are arranged in a horizontal line to form a multi-row planting section, and a plurality of planting units are arranged in the horizontal direction by the number of bars that require the plurality of planting units. By connecting them, the required number of planted portions can be easily formed, thereby reducing costs and improving maintainability.
