Abstract
(EN)
The prevent invention prevents automatic steering control when a positioning device (30) is in a second position (X2). This work vehicle (1) comprises the positioning device (30) that detects the position of a vehicle body (5) on the basis of a signal transmitted from a positioning satellite. The positioning device (30) is supported to be displaceable to a first position (X1) and a second position (X2) lower than the first position (X1). An attachment stay (47) is located below the positioning device (30) in a state in which the positioning device (30) is present in the first position (X1). As the positioning device (30) and the attachment stay (47) are integrally rotated from the state in which the positioning device (30) is present in the first position (X1), the positioning device (30) is displaced to the second position (X2), and the attachment stay (47) is located above the positioning device (30) displaced to the second position (X2) to cover the upper part of the positioning device (30), thereby preventing the automatic steering control from being performed.

La présente invention empêche une commande de direction automatique lorsqu'un dispositif de positionnement (30) se trouve dans une seconde position (X2). Elle concerne un véhicule de travail (1) qui comprend le dispositif de positionnement (30) qui détecte la position d'un corps de véhicule (5) sur la base d'un signal émis par un satellite de positionnement. Le dispositif de positionnement (30) est supporté pour pouvoir être déplacé vers une première position (X1) et une seconde position (X2) plus basse que la première position (X1). Un support de fixation (47) est situé sous le dispositif de positionnement (30) dans un état dans lequel le dispositif de positionnement (30) est présent dans la première position (X1). Lorsque dispositif de positionnement (30) et le support de fixation (47) sont mis en rotation d'un seul tenant à partir de l'état dans lequel le dispositif de positionnement (30) est présent dans la première position (X1), le dispositif de positionnement (30) est déplacé vers la seconde position (X2), et le support de fixation (47) est situé au-dessus du dispositif de positionnement (30) déplacé vers la seconde position (X2) pour couvrir la partie supérieure du dispositif de positionnement (30), empêchant ainsi la commande de direction automatique d'être effectuée.

測位装置(30)が第2位置(X2)に在るときに自動操舵制御を行うのを防止する。作業車両(1)は、測位衛星から送信された信号に基づいて車体(5)の位置を検出する測位装置(30)を備え、測位装置(30)は、第1位置(X1)と第1位置(X1)より低い位置である第2位置(X2)とに変位可能に支持され、測位装置(30)が第1位置(X1)に在る状態で測位装置(30)の下方に取付ステー(47)が位置しており、測位装置(30)が第1位置(X1)に在る状態から測位装置(30)及び取付ステー(47)が一体的に回転することで、測位装置(30)が第2位置(X2)に変位すると共に取付ステー(47)が第2位置(X2)に変位した測位装置(30)の上方に位置して該測位装置(30)の上方を覆うことで自動操舵制御を行わないように牽制する。
