[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling mounting structure of a rice transplanter in which a shoe mounted between a seedling mounting and a guide rail can be easily replaced.

[0002]

2. Description of the Related Art Conventionally, a guide rail extending left and right is disposed at a planting portion of a rice transplanter, and a seedling mounting table is slidably mounted on the guide rail so as to be slidable in the left and right direction. The seedlings are grasped from the seedling mat on the moving seedling mounting table with planting claws, and the seedlings are planted in the field in order.

[0003] At the lower part of the back surface of the seedling mounting table, a seedling mounting rail supported by a guide rail is attached vertically to the seedling mounting base via an attaching member.
The shoe is attached, the shoe comes into contact with the rail receiving surface of the rail, and the seedling mounting table is smoothly slid via the shoe. The shoe is formed in a substantially U-shape, and has a base end connected to the seedling mounting rail. In addition, the shoe is attached to the guide rail in a fitted state, and both side walls of the shoe are locked on both sides of the guide rail to prevent rattling or the like of the seedling mounting table, and to smoothly slide the seedling mounting table. Operation can be performed.

[0004]

However, the rice transplanter having the above configuration has the following disadvantages. That is, in the rice transplanter, the seedling mounting table is provided in an inclined state, and the seedling mat on the seedling mounting table is slid downward. Therefore, the seedling mounting rail and the guide are vertically mounted on the seedling mounting table. The rail receiving surface of the rail was arranged diagonally. Therefore, the weight of the seedling mounting table is applied to the upper surface and the corners of the U-shaped shoe and the guide rail, and the shoe in that part is severely worn, and a gap is formed between the shoe and the guide rail. Therefore, there is a problem that the sliding of the seedling mounting table cannot be performed smoothly.

An object of the present invention is to provide a seedling mounting structure for a rice transplanter that can solve the above-mentioned problems.

[0006]

According to the present invention, a guide rail extending left and right is provided at a planting portion provided at the rear of a rice transplanter, and a guide rail is provided on the rail via a seedling mounting rail. In a seedling mounting structure of a rice transplanter in which a seedling mounting table on which a seedling mat is mounted is slidably mounted in a lateral direction, a seedling mounting rail is slidably mounted on a rail receiving surface of the guide rail via a shoe. Further, the present invention provides a seedling mounting structure of a rice transplanter, wherein a rail receiving surface for receiving the shoe is provided in a horizontal state with respect to a front-rear direction.

[0007] In the present invention, a guide rail extending left and right is provided on a planting portion provided at the rear of the rice transplanter, and a seedling mat is mounted on the rail via a seedling mounting rail. In the seedling mounting structure of a rice transplanter in which the placed seedling mounting is slidably mounted in the left and right direction, the seedling mounting rail is slidably mounted on the rail receiving surface of the guide rail via a shoe. The rail receiving surface for receiving the seedlings is provided horizontally in the horizontal direction with respect to the front-rear direction, and the seedling mounting rail abutting on the rail receiving surface is attached at a predetermined angle, and the seedling mounting table and the seedling mounting table are mounted. There is provided a seedling mounting structure of a rice transplanter, wherein a space is provided between the rail and a part of a vertical feed belt provided on the seedling mounting table.

[0008]

[Effects of the Invention] In the present invention, the seedling table is slid left and right through the seedling table rails along the guide rails provided in the planting section, and the seedlings are picked from the seedling mat and planted in the field. At that time, attach the horizontal seedling mounting rail to the rail receiving surface of the guide rail that is horizontal with respect to the front-rear direction, and weight the seedling mounting table with the rail receiving surface. As a result, only the contact surface of the shoe that comes into contact with the rail receiving surface is worn, preventing the occurrence of a gap between the shoe and the guide rail, and allowing the seedling mounting table to slide smoothly. it can.

Also, the seedling mounting rail is attached to the seedling mounting table at a predetermined angle to make the rail horizontal, and at this time, a space is provided between the seedling mounting table and the seedling mounting rail. By installing a part of the vertical feed belt provided on the seedling mounting table in the same space, the range of seedling feed of the belt is expanded, the engagement with the seedling mat is ensured, and the mat is transported. The trouble caused by the above can be eliminated.
