PROBLEM TO BE SOLVED: To provide an auxiliary device for loading a dispersion object capable of largely reducing a burden of work for supplying a dispersion object such as a fertilizer and improving work efficiency.SOLUTION: An auxiliary device A for loading a dispersion object is for a worker to ascend/descend when a fertilizer in a bag is loaded into a hopper b1 of a dispersion machine B mounted above a tillage rotary D at a rear part of a tractor C. The auxiliary device includes: a support frame member constituted by a pair of horizontal frame members 1a in a machine body width direction connected with and supported by a pipe frame d of the tillage rotary D on one edge side and a pair of vertical frame members 1b connected rotatably with the other edge side of the pair of horizontal frame members 1a at one edge side and step members 2, 3 supported and arranged at upper and lower two positions on the pair of horizontal frame members 1a and between the pair of vertical frame members 1b.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】、簡易な構成で、散布物である肥料などの補給作業の大幅な負担軽減と作業効率の向上を可能とする散布物投入補助装置を提供する。【解決手段】トラクタC後部の耕耘ロータリD上に搭載された散布機Bのホッパb1内に袋入り肥料を投入するときに、作業者が上り下りする散布物投入補助装置Aであり、一端側が耕耘ロータリDのパイプフレームdに連結支持される機体幅方向一対の横枠部材1aと、一対の横枠部材1aの他端側に一端側が回動可能に連結される一対の縦枠部材1bとで構成される支持枠部材1と、一対の横枠部材1a上と一対の縦枠部材1b間との上下2カ所に支持配置されるステップ部材2,3とを備えている。【選択図】図1
