PROBLEM TO BE SOLVED: To provide a self-propelled pest control machine enabling a boarding boom operation switch lifting a pest control boom to be safely and easily operated when a worker boards a travel vehicle body.SOLUTION: A cabin 20 a worker boards is arranged in a front part of a travel vehicle body 2 travelling with front wheels 6 and rear wheels 7 and a chemical tank 30 is mounted in a rear part. A pest control boom 40 arranged in a front part of the cabin 20 comprises a center boom 40a and side booms 40b, 40b arranged in the right/left of the center boom so as to rotate inward/outward and stand/lie. A self-propelled pest control machine can be switched between a pest control work posture extending the side booms 40b, 40b to the right/left and a storage posture having the side booms along right/left side parts of the cabin 20 so as to be higher toward backward. Boom side guards 50 receiving the side booms 40b, 40b rotating inward are arranged in side parts of the cabin 20. A lifting/lowering switch attachment frame storing a boom operation switch box 65 is attached in a lower side of the boom side guard 50, the boom operation switch box operating the side booms 40b, 40b to be lifted/lowered.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】作業者が走行車体に搭乗する際に防除ブームを上昇させる乗降用のブーム操作スイッチを安全に操作し易くした自走式防除機を提供する。【解決手段】前輪6と後輪7で走行する走行車体2の前部に作業者が搭乗するキャビン20を設けて後部に薬剤タンク30を搭載し、キャビン20の前部に設ける防除ブーム40をセンターブーム40aとその左右に内外回動と起伏可能に設けるサイドブーム40b,40bで構成し、サイドブーム40b,40bを左右に伸ばした防除作業姿勢とキャビン20の左右側部に後上がり姿勢で沿わせた収納姿勢に切換え可能にした自走式防除機において、キャビン20の側部に内側回動するサイドブーム40b,40bを受けるブーム側部ガード50を設け、ブーム側部ガード50の下側にサイドブーム40b,40bを昇降操作するブーム操作スイッチボックス65を収納した昇降スイッチ取付枠を取り付けた。【選択図】図1
