PROBLEM TO BE SOLVED: To provide a self-propelled pest control machine that prevents a chemical liquid in a spray state from entering into a cabin.SOLUTION: A self-propelled pest control machine incudes: a cabin 20 in a travel vehicle body serving as an operator steering chamber； a pest control boom 40 configured to be switched between a chemical liquid spray posture extending in a right/left direction and a storage posture extending in a front/rear direction in a side of the cabin； and a chemical liquid tank 30 at a rear part of the cabin. The self-propelled pest control machine can travel with right/left front wheels 6 and right/left rear wheels 7. The self-propelled pest control machine further includes: a right/left opening/closing door for getting on/off the cabin； a right/left opening/closing switch for opening/closing the right/left opening/closing door； a right/left door motor for moving the right/left opening/closing door； a right/left door sensor for detecting an opening/closing state of the right/left opening/closing door； and a concentration sensor 80 for detecting concentration of the chemical liquid outside the cabin. When a chemical liquid concentration at a predetermined value or higher is detected by the concentration sensor, warning is made in the cabin.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2018,JPO&INPIT【課題】キャビン内に噴霧状態の薬液が入らない自走式防除機を提供する。【解決手段】走行車体にオペレータ操縦室となるキャビン２０と、左右方向に延びる薬液散布姿勢、及びキャビンの側方を前後方向に延びる収納姿勢に切り替え可能に構成した防除ブーム４０と、前記キャビンの後方に薬剤タンク３０を備え、左右前輪６及び左右後輪７で走行可能な自走式防除機において、前記キャビン内に乗降する左右の開閉扉を設け、左右の開閉扉を開閉させる左右の開閉スイッチと左右の開閉扉を動かす左右のドアモータと左右の開閉扉の開閉状態を検出する左右のドアセンサを設け、キャビン外に薬液の濃度を検出する濃度センサ８０を設け、薬液濃度が所定値以上であることを前記濃度センサが検出すると、キャビン内で警告を報知する構成としたことを特徴とする自走式防除機の構成とする。【選択図】図２
