PROBLEM TO BE SOLVED: To provide a self-propelled pest control machine capable of preventing closing failure of an entrance opening/closing door so as not to allow chemical liquid in a spray state to enter a cabin.SOLUTION: A self-propelled pest control machine includes: right/left opening/closing doors for getting in/off a cabin right/left opening/closing switches 70L, 70R opening/closing the right/left opening/closing doors right/left door motors 74L, 74R moving the right/left opening/closing doors right/left door sensors 71L, 71R detecting an opening/closing state of the right/left opening/closing doors and a spray switch 72 turning of/off liquid spray from a pest control boom. When the right/left door sensors detect closing of the right/left opening/closing doors, the spray switch is turned on to enable spray. When a speed sensor 120 detects forward travel or backward travel, a pest control pump 75 is driven to start spray of chemical liquid from the pest control boom. During the spray, the right/left opening/closing doors do not open even if the right/left opening/closing switches are operated.SELECTED DRAWING: Figure 8COPYRIGHT: (C)2018,JPO&INPIT【課題】キャビン内に噴霧状態の薬液が入らないように、乗降用の開閉ドアの閉め忘れを防止できる自走式防除機を提供する。【解決手段】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70L、70Rと、左右の開閉扉を動かす左右のドアモータ74L、74R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71L、71Rと、防除ブームから薬液散布を入り切りする散布スイッチ72を設け、前記左右の開閉扉が閉じていることを前記左右のドアセンサが検出すると、前記散布スイッチを入りにして散布可能な構成とし、車速センサ120が前進走行又は後進走行を検出すると防除ポンプ75を駆動して前記防除ブームから薬液の散布を開始する構成とし、散布中は前記左右の開閉スイッチを操作しても左右の開閉扉は開かない構成とした。【選択図】図8
