DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to planting of a rush planting machine in which a guide rail for supporting a seedling table so as to be able to reciprocate and traverse is formed with a take-out opening for taking out seedlings into which planting claws can enter. Part structure.

[0002]

2. Description of the Related Art Conventionally, in the planting portion structure of the above-mentioned rush planting machine, the planting claw is formed to have the same width at the distal end portion and the base end portion, and the planting claw is provided at a take-out opening for taking out a seedling. A considerable gap is formed between the outlet and the planting claw so as to reliably avoid collision between the planting claw and the vicinity of the outlet in the state of entering.

[0003]

However, according to the above-described conventional configuration, there are the following problems. That is,
The rush seedlings are much more rooted than the rice seedlings, and a gap is formed between the extraction opening and the planting nails with the planting nails entering the extraction opening for taking out the seedlings If, for example, the seedling mass is unevenly distributed within the width of the seedling removal from the seedling mounting table, when the tip of the planting claw comes into contact with the seedling mass, lateral force is applied and planting is performed. There is a possibility that the claw is displaced backward in that direction.

[0004] Further, a partition wall is provided at the lower end of the seedling mounting table to divide the seedling mounting width of the seedling mounting table into a plurality of width portions in the horizontal direction at a predetermined pitch, so that the extracted seedling and the succeeding seedling can be accurately separated. In the model of the specification that is configured as described above, the planting claws displaced in the lateral direction due to the contact with the seedling mass may collide with the partition wall and damage the planting claws and the partition wall as described above. there were.

[0005] An object of the present invention is to suppress the lateral displacement of the planting claws even when the seedling mass is unevenly distributed within the width of the seedlings taken out of the seedling mounting table. It is an object of the present invention to provide a planting portion structure of a rush transplanter that allows good seedling removal.

[0006]

According to a first aspect of the present invention, there is provided a guide rail for supporting a seedling mounting table so as to be able to reciprocate in a reciprocating and lateral manner. In the planting portion structure of the formed rush transplanter, the take-out port is provided with a pair of left and right sliding contact walls forming left and right edges of the take-out port, and the planting arm having the planting claw mounted thereon. A guide member having a width smaller than the left-right space between the pair of left and right sliding contact walls and having a width wider than the width of the planting nail is fixed to the nail mounting portion, and the seedling is formed by the planting nail. The guide member is configured to pass between the sliding contact walls in accordance with the take-out operation.

According to a second aspect of the present invention, there is provided a guide rail for supporting a seedling table so as to be able to reciprocate and traverse laterally, wherein a take-out opening for taking out a seedling into which a planting claw can enter is formed. At the lower end of the seedling mounting base, in the planting part structure of the rush transplanter, which is provided with a partition wall that divides the seedling mounting width of the seedling mounting base into a plurality of widths in the horizontal direction at a predetermined pitch, A pair of left and right sliding contact walls forming left and right edges of the outlet are provided, and the claw attachment portion of the planting arm to which the planting claw is attached is narrower than the left and right interval between the pair of left and right sliding contact walls, Also, a guide member having a lateral width wider than the lateral width of the planting nail is fixed, and the guide member passes between the sliding contact walls with the operation of taking out the seedling by the planting nail. The point is that it is configured.

[0008]

According to the first aspect of the present invention, when the planting claw grasps and removes a seedling, the wide guide member is located on the base end side of the planting claw. Therefore, when a lateral force is applied to the tip side of the planted nail due to the contact of the planted nail with the seedling mass, it is considered that the planted nail is going to be displaced in the lateral direction as a whole, at the outlet side. By sliding the side end of the guide member, which has greater strength than the planting claw, against the sliding contact wall of the planting claw to suppress lateral movement of the mounting base end of the planting claw, the planting claw distal side Of the vehicle in the lateral direction.

According to a second aspect of the present invention, as described above,
Sliding contact between the wide base end of the planting claw and the sliding wall of the outlet prevents the tip of the planting claw from retreating in the lateral direction, and the planting claw can collide with the partition wall. Less likely.

[0010]

According to the first aspect of the present invention, since the clumps of the seedlings are unevenly distributed in the width of the seedlings taken out of the seedling placing table, the lateral direction of the planting claw tip side is caused. Even if a force is applied, the position of the claw proximal end by the sliding contact between the guide member and the sliding contact wall suppresses the lateral retreat displacement of the planted claw tip at the time of seedling removal. In addition, there is an advantage that an appropriate amount of seedlings can be easily taken out.

According to the second aspect of the present invention, it is possible to prevent the planting claws from colliding with the partition wall, so that an appropriate amount of seedlings can be taken out without dragging the succeeding seedlings, and the planting claws and the partition wall can be removed. It is possible to provide a planting portion structure of a rush transplanter having excellent durability and capable of reliably preventing breakage.
