PROBLEM TO BE SOLVED: To provide a chemical spreader which enables efficiently and accurately performing operation of chemical spraying to soil at positions where crop seedlings are planted or to the periphery of the planted crop seedlings with one-touch operation in a standing attitude while reducing a physical burden.SOLUTION: The chemical spreader includes a support body 3 having an inlet 31 and an outlet 32, a sliding body 5 having a measuring and retaining part 51, an operation member 8 mounted to the sliding body 5, a chemical tank 1 storing a chemical P, and a ground contact member 44 attached to the support body 3. The sliding body 5 is vertically slidable between an inflow position where the measuring and retaining part 51 communicates with the inlet 31 and the chemical P from the chemical tank 1 flows into the measuring and retaining part 51 and an outflow position where the measuring and retaining part 51 communicates with the outlet 32 and the chemical P in the measuring and retaining part 51 flows out.COPYRIGHT: (C)2013,JPO&INPIT【課題】 作物苗の植付位置の土壌あるいは苗を植え付けた後の苗周辺への薬剤散布を、立ったまま、ワンタッチの操作で、肉体的負担を軽減して効率よく、かつ精度よく作業を行うことができる薬剤散布器を提供すること。【解決手段】 流入口31及び流出口32を有する支持本体3と、計量保持部51を有する摺動体5と、摺動体5に装着された操作部材8と、薬剤Pが貯留された薬剤タンク1と、支持本体3に取り付けられた接地部材44と、を備えた薬剤散布器。摺動体5は、計量保持部51が流入口31に連通して薬剤タンク1からの薬剤が計量保持部51に流入する流入位置と、計量保持部51が流出口32に連通して計量保持部51内の薬剤Pが流出される流出位置との間を上下方向に摺動自在である。【選択図】図1
