Description

[Detailed explanation of the invention] "Industrial application field" This invention is a rice transplanter that uses a planting claw to take out one seedling from a seedling stand that moves back and forth from side to side and sequentially plant it in a field. Regarding equipment.

``Prior Art'' As shown in Japanese Utility Model Publication No. 48-19063, there has been a technique in which a belt for guiding seedlings is provided on the seedling take-out side of a seedling stand so as to be movable laterally.

"Problems to be Solved by the Invention" In the prior art, since the belt is stretched except for the seedling take-out port, it is necessary to form a front side opening for the seedling take-out port on the side of the belt. In addition, since the seedling stand and the belt are connected, the belt attachment structure cannot be easily simplified, and attaching/detaching and replacing the belt is troublesome. I had the above problem.

``Means for Solving the Problems'' However, the present invention is a rice transplanter in which a belt for guiding seedlings is provided on the seedling take-out side of the seedling stand so as to be movable laterally. A notch is formed on the side of the seedling take-out port of the seedling take-out plate disposed in the seedling take-out plate, and a bracket that connects both sides of this notch is removably fixed to the seedling take-out plate, and a pin is attached to the bracket to allow rotation and detachment of the guide. The present invention is characterized in that a roller is provided, and the belt is tensioned so as to be rotationally movable and detachable via a guide roller.

``Function'' Therefore, since a notch is created in the seedling take-out plate and the belt is stretched, there is no need to form a seedling take-out port at the end of the belt as in the past, and the seedling cutting action at the seedling take-out port is stabilized. In addition, the belt can be attached and detached by simply removing the pin and detaching the guide roller, and the notch of the seedling removal plate can be easily reinforced by a bracket supported by the belt. The belt attachment structure can be simplified more easily than in the past.
