Abstract

PURPOSE:To perform sure longitudinal transfer of a mat-shaped seedling by laterally placing a plurality of long openings in parallel interposing intermediate bars between the operatings on a seedling-placing face of a seedling table, extending a broad transfer belt from the back of the seedling table to the opening and circulating the belt with a longitudinal transfer mechanism. CONSTITUTION:A plurality of long openings are laterally placed in parallel on a seedling-placing face of a seedling table 4 interposing intermediate bars 4a between the openings, a broad transfer belt 13 is extended from the back of the seedling table to the opening and the belt 13 is engaged with a belt- driving roller 9 at a region having the intermediate bars. The sagging of the transfer belt can be reduced and the float of the belt from the driving roller can be depressed by this structure.

In the current rice transplanter, seedlings are planted by moving the seedling table horizontally back and forth from side to side.
- When reaching the end, it is equipped with a vertical feeding mechanism that sends the matted seedlings downward to the seedling take-out port side.
As disclosed in Japanese Patent No. 25725, there is a model equipped with a vertical feeding mechanism in which a feeding belt is wound around a driving pulley and a driven pulley.

In the above-mentioned feeding belt type, since the feeding belt 1~ contacts a wide area on the back side of the mat-shaped seedlings, it can be expected that vertical feeding can be performed relatively reliably, but conversely, most of the weight of the mat-shaped seedlings will hang on the feed belt, causing the middle of the feed belt to bend. In order to apply sufficient tension to the feed belt, the driven lector is supported so that it can slide freely, and the feed belt is placed under tension.
It is conceivable to provide an auxiliary roller or the like between the driving roller and the driven roller to support the deflection, but this would complicate the structure and increase production costs.
Therefore, there was some lag in terms of practical application.

The present invention resides in configuring the seedling feeding structure of a rice transplanter as follows. In other words, multiple vertically long openings are arranged side by side on the seedling surface of the seedling rack via middle crosspieces, and a wide feeding belt wound around a driving roller and a driven roller is run from the back of the seedling rack. The mechanism is such that the feed belt is faced across the plurality of adjacent openings, and that the drive roller and the feed belt are engaged with each other at the portion where the middle crosspiece is present to rotationally drive the feed belt. And the effects are as follows.
