PROBLEM TO BE SOLVED: To provide a chemical spraying apparatus for a speed-sprayer in which an operation for stoppage (or the cancel of stoppage) of spray to a partial area is simplified, operation efficiency is improved and defects of scattering of the chemical on an undesirable area and wasteful use of the chemical are avoided.SOLUTION: The chemical spraying apparatus for the speed-sprayer is provided with: a chemical spray mechanism 2 for spraying the chemical to a specified area in the spraying direction a blocking cover 3 for blocking a partial area An in the specified area to restrict the spray of the chemical and a cover moving means 4 for moving the cover selectively to a blocking position Xs for blocking the partial area An or to a releasing position Xr for releasing the blocking, and is further provided with a chemical supply interlocking means 5 for stopping the supply of the chemical to be sprayed on the partial area An when the blocking cover 3 is moved to the blocking position Xs side and for releasing the stoppage of the supply when the blocking cover 3 is moved to the releasing position Xr side.COPYRIGHT: (C)2008,JPO&INPIT【課題】 一部範囲に対して噴霧を停止(又は停止解除)する際の操作の単純化、更には作業能率の向上を図るとともに、無用な場所への薬液の飛散、更には薬液が無駄になる不具合を回避する。【解決手段】 放射方向の所定範囲に薬液を噴霧可能な薬液噴霧機構2と、所定範囲における一部範囲Anを遮断して薬液の噴霧を規制する遮断カバー3と、この遮断カバー3を、一部範囲Anを遮断する遮断位置Xs又はこの遮断を解除する開放位置Xrに選択的に移動可能なカバー移動手段4を備えるとともに、遮断カバー3が遮断位置Xs側へ移動した際に一部範囲Anに噴霧する薬液の供給を停止し、かつ遮断カバー3が開放位置Xr側へ移動した際に供給の停止を解除する薬液供給連動手段5を設ける。【選択図】 図1
