Description

TECHNICAL FIELD The present invention relates to an implanting device for a transplanter and can be used for transplanting seedlings of vegetables.

2. Description of the Related Art As a conventional technique, as described in JP-A-59-203410, the bottom plate of a seedling box frame that houses a seedling box in a vertically movable manner is used as a lower part of a soil-grown seedling in the seedling box. The seedling extruding rods are formed so as to close all but one lateral row, and the seedling box frame is moved laterally and the seedling box is moved vertically so that the soiled seedlings in the seedling box are removed by the seedling pushing rod. With a substantially upright posture in a lower position, one plant is dropped into a planting device below and the planting device is reciprocally moved up and down to perform planting.

Problems to be Solved by the Invention Conventionally, in planting seedlings of vegetables and the like, generally, seedlings with soil are planted by plunging them into a lower planting device with a substantially vertical posture by a seedling pushing rod. Many of these are in the form, and in this form, a cylindrical planting device whose lower end can be opened and closed is reciprocally moved up and down between the upper seedling supply device and the lower planted soil surface for soil attachment. The seedlings are planted on the soil surface, but if the diameter of the tubular part of the planting device for inheriting the seedlings dropped by the extrusion rod from the seedling feeding device is large during this planting, the drop position can be easily aligned. However, if the degree of freedom of the seedlings is too large, the upright posture of the seedlings becomes unstable and the planting performance deteriorates. There is a concern that the leaves of the seedlings may be damaged and their survival may deteriorate. In addition, when the seedlings are planted and placed on the soil surface by opening and closing the tubular tip, it is difficult to correct the placement posture by this method, so it is difficult to perform stable placement because the posture of the seedlings tilts or falls.

Therefore, the present invention is intended to solve the above problems and to maintain a normal planting and standing posture without damaging the seedlings.

Means for Solving the Problems In the present invention, a rotating case (2) in which a base is rotatably supported by a machine body and reciprocally rotates between an upper seedling feeding device (1) and a lower soil surface. A seedling holder (3) for holding and taking out the seedlings from the seedling supply device (1) and planting the seedlings in the soil is attached to the tip of the seedling feeding device (1), and the descending direction of the seedling holding tool (3) is set in the rotating case (2). Structure of implanting device of transplanter provided with interlocking mechanism for rotating seedling holder (3) in the opposite direction to the rotating direction of rotating case (2) in the seedling holding posture regardless of rotation And

Advantageous Effect of the Invention The present invention has a tip end portion of a rotating case (2) whose base is rotatably supported by a machine body and reciprocally rotates between an upper seedling feeding device (1) and a lower soil surface. , A seedling holder (3) for holding and taking out the seedlings from the seedling supply device (1) and planting the seedlings in the soil is mounted, and the turning case (2) is concerned with turning in the descending direction. Since the seedling holder (3) is provided with an interlocking mechanism for rotating the seedling holding tool (3) in the seedling holding posture in a direction opposite to the rotating direction of the rotating case (2), the transplanter is an implanting device. The soil is securely held by the seedling holder (3) from the seedling supply device (1), and the seedling holding posture is maintained regardless of the downward movement of the rotating case (2). You can plant seedlings on the surface, and when planting seedlings on the soil surface, the planting posture tilts or falls,
In addition, it is possible to prevent damage to the leaves and the like, and it is possible to plant seedlings in a stable and normal posture.
