PROBLEM TO BE SOLVED: To provide a chemical spraying work vehicle including a chemical spraying boom preventing heat generation of a drive motor of a telescopic boom even if frequently sliding the telescopic boom during chemical spraying work and preventing a defect of reduction in a slide speed of the telescopic boom.SOLUTION: The chemical spraying work vehicle includes: a side boom 44 connected so as to open/close on both sides of a center boom 43 of a chemical spraying boom 19 to which a chemical is fed from a chemical tank 18 on a vehicle body 1, the side boom 44 constituted by a base boom 44a and a telescopic boom 44b slidable with respect to the base boom 44a; a main drive motor 8 driving the telescopic boom 44b to slide and installed in the base boom 44a; and an auxiliary drive motor 9 of the telescopic boom 44b arranged at a tip of the telescopic boom 44b. Installment of the plural drive motors 8, 9 to slide the boom 44b prevents reduction of drive torque and reduction of a slide speed of the telescopic boom 44b even if the telescopic boom 44b is frequently subjected to telescopic motion during chemical spraying work in a deformed farm field or the like.

    【課題】薬液散布作業中に伸縮ブームを頻繁にスライドさせても伸縮ブームの駆動モータの発熱が無く、伸縮ブームのスライド速度が低下する欠点のない薬液散布ブームを備えた薬液散布作業車を提供すること。【解決手段】車体1上の薬液タンク18から薬液を供給される薬液散布ブーム19のセンタブーム43の両側に開閉自在に連結したサイドブーム44を、基本ブーム44aと基本ブーム44aに対してスライド自在の伸縮ブーム44bから構成し、伸縮ブーム44bをスライド駆動させる主駆動モータ8を基本ブーム44aに設け、伸縮ブーム44bの先端部に伸縮ブーム44bの補助駆動用駆動モータ9を設けた薬液散布作業車であり、変形圃場などで薬液散布作業中に伸縮ブーム44bを頻繁に伸縮しても、該ブーム44bをスライドさせる駆動モータ8、9を複数設けたことで、駆動トルクが低下することがなく、伸縮ブーム44bのスライド速度が低下することもない。【選択図】図8
