Title
(EN) WORK VEHICLE FOR AGRICULTURE
(JA) 農業用散布作業車
Abstract
(EN)

PROBLEM TO BE SOLVED: To solve a problem that an operator must ride and drive a spraying work vehicle to a place in a paddy field, stop the vehicle at a work-starting position, and then walk in the rice-planted paddy field to its levee to leave the paddy field.

SOLUTION: This work vehicle 101 for the agriculture, on which the mobile station 103 of a GPS unit 102, internal sensors 122, and a stock-following sensor 123 are loaded, is characterized in that an automatic travel-starting point (work vehicle-approaching point 127) and a work-starting point 128 can be set at different places, respectively.

【課題】例えば、水田で散布作業機を使用する場合、水田の中まで該散布作業車に乗って走行し、作業開始位置で停車させた後、オペレータは稲の植わった水田の中を歩いて畦まで戻ることにより圃場の外に退出しなければならず、オペレータの負担となっていた。
【解決手段】GPSユニット102の移動局ユニット103と、内界センサ122と、株倣いセンサ123とを搭載し、自律走行開始地点(作業車進入地点127)と作業開始地点128とを異なる場所に設定可能に農業用作業車101を構成した。
