Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention mainly relates to a planting device for a vegetable transplanter that receives potted seedlings for one strain taken out from a seedling tray of a seedling placing table by a planting claw and sequentially plants them in a field.

[0002]

[Prior Art]

 When seedlings are planted with this type of planting nail, soil adheres to the inside and outside of the planting nail depending on the soil moisture condition and the type of soil, especially when the seedlings penetrate inside the planting nail. Since the depth also becomes shallow and it becomes a shallow planting state, when soil adhered, soil was removed manually each time.

[0003]

[Problems to be solved by the device]

 However, in the case of such manual work, the operator not only needs to constantly observe the soil attachment state of the planting nail, but also has to interrupt the work and clean each time the soil adheres. There was a troublesomeness and poor workability.

[0004]

[Means for Solving the Problems]

 Therefore, the present invention has a structure in which pot seedlings taken out from the seedling tray of the seedling mounting table are received by the planting claws and sequentially planted in the field, and the upward movement of the elliptical planting locus of the planting claws is performed. A cleaning member that makes sliding contact with the inner peripheral surface of the planting claw is provided near the locus, and the inner peripheral surface of the planting claw is cleaned with the cleaning member when the upper movement of the planting claw returns. This enables stable seedling transplantation while automatically maintaining the depth.
