Abstract

L'invention concerne une repiqueuse de riz 1 qui comprend : un corps de déplacement 2 ; un dispositif de plantation de semis 21 disposé derrière le corps de déplacement 2 ; des tables de semis supplémentaire gauche et droite 31 sur lesquelles un semis supplémentaire à fournir au dispositif de plantation de semis 21 peut être monté ; des cadres de support gauche et droit 34 s'étendant respectivement vers le haut à partir des tables de semis supplémentaire gauche et droite 31 ; un cadre unitaire 35 relié aux cadres de support gauche et droit 34 ; et une unité de télémétrie 36 qui est supportée sur le cadre unitaire 35 et acquiert des informations de position du corps de déplacement 2. L'unité de télémétrie 36 peut pivoter vers l'avant du corps autour d'un axe de pivotement gauche-droite 35a et peut ainsi commuter à un état d'utilisation, qui est positionné plus haut que l'extrémité supérieure des cadres de support 34, et un état rétracté qui est être positionné plus bas que l'extrémité supérieure des cadres de support 34.
