[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling stand for a rice transplanter.

[0002]

2. Description of the Related Art Conventionally, in a seedling mounting table of a multi-row planting type rice transplanter, only a set seedling of a specific row is taken out from a plurality of placed seedlings corresponding to each planting row at a ridge. There is a seedling stopper that prevents the transfer of the seedlings to the side, and has a function of switching between a state of blocking the transfer of the placed seedlings to the seedling take-out side and a state of canceling the blocked state.

In addition, there is one that prevents the seedling from floating by simply pressing the placed seedling placed on the seedling placing table from above with a pressing body.

[0004]

However, in the conventional example described above, in the case where the seedling stopper for stopping the supply of the placed seedlings is simply provided on the seedling placing table, the placed seedlings float up,
Further, if the pressing body for pressing the seedlings is simply provided on the seedling placing table, the supply of the placed seedlings cannot be stopped. Therefore, there has been a demand for a device capable of supplying the placed seedlings appropriately by equipping the seedling placing table with both means for stopping the feeding of the placed seedlings and means for suppressing the floating of the placed seedlings. .

[0005]

According to the present invention, a bracket is provided near a seedling take-out port on a seedling table provided in an inclined posture such that the seedling take-out port is located in a lower position, and a bracket of a seedling stopper is provided on the bracket. By pivoting the end and swinging the seedling stopper, it is possible to switch between the state of blocking the transfer of the placed seedling to the seedling take-out port side and the blocking release state, while on both side surfaces of the seedling mounting table, Attach the seedling retainer to prevent the soil of the placed seedlings from floating up so that it is positioned higher than the base end of the seedling stopper via the mounting metal, and attach the seedling retainer directly to the soil. A pressing rod that acts to prevent lifting is formed by extending in the front-back direction along the upper surface of the seedling mounting table, and the tip of the pressing rod is located near the bracket that pivotally attaches the seedling stopper. Moreover, the front-rear length of the pressing rod is at least larger than the swing radius of the seedling stopper. When the seedling stopper is in the state of preventing lifting of the bed soil of the placed seedlings and the seedling stopper is in the state of blocking the placement of the placed seedlings, a notch is formed in the tip of the seedling stopper. The presser bar is fitted in the notch, and is configured to have a cross shape in a side view without interfering with each other.
