移植機の苗取り出し装置

Seedling taking out apparatus of transplanter

Abstract

【課題】苗取り爪を苗爪台に対して取り付け、苗取り爪先端の拡縮と苗取り爪からの苗の放出とを行う苗取り補助具を、苗爪台及び苗取り爪に対して長手方向相対移動自在に支持して、苗取り出し及び苗放出の高速化を可能にする。 【解決手段】苗爪台33と、苗爪台に基部が枢支されかつ先端間隔Lが拡縮可能に取り付けられた左右苗取り爪32と、苗取り爪を苗トレイTのポット部Pに進退させて苗Nを突き刺して取り出すべく苗爪台を移動させる手段と、左右苗取り爪に先端が嵌合しかつ苗爪台に苗取り爪長手方向相対移動自在に支持されている苗取り補助具34と、苗取り爪をポット部に進入したときに苗取り爪の先端間隔Lを収縮させるべく苗取り補助具を苗取り爪の先端側から基部側へ移動し、ポット部の外で苗取り爪から苗を押し出すべく苗取り補助具を苗取り爪の基部側から先端側への移動させる補助具作動手段39とを有する。 【選択図】  図1
<P>PROBLEM TO BE SOLVED: To increase the speed of a seedling-taking out and releasing work by attaching a seedling taking out pawl to a seedling pawl bed and supporting a seedling take out assisting tool in a manner longitudinally movable relatively to the seedling pawl bed and the seedling taking out pawl and expanding and contracting the tip ends of the seedling taking pawls and the release of the seedling from the pawls by the use of the assisting tool. <P>SOLUTION: This seedling taking out apparatus is provided with the seedling pawl bed 33, a pair of right and left seedling taking out pawls 32 whose base parts are pivoted with the seedling pawl bed in a manner to enable the expansion and contraction of the tip intervals L of the pawls, a means for moving the seedling pawl bed to move the seedling taking out pawls forward and backward relatively to the pot P of a seedling tray T to thrust and take out the seedling N, a seedling take out assistant 34 fitting its tip end with the right and left seedling taking out pawls and supported on the seedling pawl bed in a manner longitudinally movable relatively to the seedling taking out pawls, and a means 39 for moving the assistant tool from the tip ends of the seedling taking pawls to the base part for contracting the gap between the tip ends of the pawls when the pawls are introduced into the pot and moving the assistant tool from the base to the tip ends of the pawls for pushing the seedling out of the pawls outside of the pot. <P>COPYRIGHT: (C)2004,JPO
