Abstract

PURPOSE:To carry out smooth planting motion of seedling by providing a vertically movable partition tool at a specific position while interlocking with operation of seedling-retaining tool above the vicinity of seedling-taking out port of seedling carrying table. CONSTITUTION:When a seedling retaining tool 6 is situated at backward retreating position, a rocking arm 30 is rocked to backward side against a spring 31 by pulling wire 29 and partition tool 23 is retreated upward. Tensile force of wire 29 is weakened and rocking arm 30 is rocked forward by pressing force of spring 31 and partition tool 23 is moved below as the seedling retaining tool 6 is moved forward toward seedling take out port 5. When the partition tool 23 is moved below, the lower end part of partition tool 23 formed in sharpened state acts on the root of the seedling (a) and separation between a seedling to be planted and seedling on the side can surely be carried out. The partition tool 23 is formed in sheet-like form along the longitudinal direction and lateral falling of the seedling (a) is effectively prevented.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a seedling transplanter for transplanting crop seedlings such as rush, and more specifically, the present invention relates to a seedling transplanter for transplanting crop seedlings such as rush grass, and more specifically, the present invention relates to a seedling transplanter for transplanting crop seedlings such as rush grass, etc. A planting mechanism is configured to take out the seedlings one by one from the seedling take-out port and plant the seedlings one by one. The present invention relates to a seedling transplanter equipped with a seedling holder that holds the seedlings and forcibly moves the seedlings to the seedling take-out port.

[Conventional technology]

Conventionally, in the above-mentioned seedling transplanting machines, there has been a structure in which a plate-shaped support member for receiving and supporting the upper part of the stem of the placed seedling is provided above the seedling take-out port of the seedling stand (for example, in the present application). (See Japanese Patent Application No. 1-321639).

[Invention or problem to be solved]

The above conventional structure receives and supports seedlings in an upright position while
Moreover, the operation of the planting mechanism is not obstructed when taking out seedlings.

However, crop seedlings such as rushes have relatively hard stems and roots;
The seedling stand reciprocates left and right with a constant stroke, and the sliding rail forming the seedling take-out port is provided in a fixed position, so the lateral posture of the leading seedling tends to become unstable. If the action of taking out the seedlings is carried out in such a state where the seedlings have fallen sideways, there is a risk that the seedlings may be accidentally bent further in the direction of falling sideways by the seedling holder, causing damage, and this has the drawback that smooth planting cannot be carried out. .

The present invention aims to solve the above-mentioned problems.

[Means to solve the problem]

A characteristic configuration of the present invention is that, in the seedling transplanting machine described at the beginning, a part of the seedling holder is placed above the seedling take-out opening in conjunction with the operation of the seedling holder, so that the lower end or the root part of the seedling is The main feature is that a rake-shaped partition is provided that can be moved up and down between an active position and an upwardly retracted position.

[For production]

The leading seedling on the side of the seedling outlet is supported by a rake-like partition that is long in the vertical direction, and its horizontal posture is stabilized. In addition, since the partition moves up and down, it does not interfere with the action of the planting mechanism to take out the seedlings by retracting the partition up and down, and when it moves downward, its lower end acts on the roots of the seedlings, making it easier to remove the seedlings from the seedling holder and the planting mechanism. Planting using this mechanism maintains symmetry and allows for smooth horizontal separation of seedlings.

〔Effect of the invention〕

Therefore, according to the present invention, by adding a member with a rational structure, the lateral posture of the leading seedling is stabilized, the risk of damage to the seedling is reduced, and the number of seedlings in the plant is stabilized, As a result, we have been able to prevent the occurrence of missing plants and have been able to provide a plant that can be planted smoothly.
