PROBLEM TO BE SOLVED: To provide a granule applicator of an application machine, which can ensure granule application at a small flow rate in prescribed uniform application precision and can efficiently treat fertilizer application at a large flow rate.SOLUTION: The granule applicator of the application machine, including a tank (11) for receiving chemical granules, a delivering part (12) for delivering a constant amount of granules from the bottom of the tank, the first jetting pipe (13) for air-conveying the granules received from the delivering part (12), and the second jetting pipe (14) communicated with the first jetting pipe (13) to apply the granules, is characterized in that the delivering part (12) includes two delivering rolls (15) whose rotation speeds can separately be controlled, in parallel, and is communicated with the first jetting pipe (13). Uniform application at a small flow rate can be ensured, and granule application at a large flow rate is capable in high speed travel.COPYRIGHT: (C)2011,JPO&INPIT【課題】所定の一様散布精度による小流量の薬剤散布を確保するとともに、大流量の肥料散布を能率良く処理することができる散布機の粒剤散布装置を提供する。【解決手段】散布機の粒剤散布装置は、薬肥粒剤を収容するタンク(11)と、その底部から粒剤を定量繰出しする繰出部(12)と、この繰出部(12)から受けた粒剤を送風搬送する第1噴管(13)と、この第1噴管(13)と連通して粒剤を散布する第2噴管(14)とを備えて構成され、上記繰出部(12)は、回転数の個別制御が可能な2つの繰出ロール(15)を並列に構成するとともに第1噴管(13)に共に連通することにより、小流量時の一様散布を確保しつつ、高速走行で大流量の粒剤散布が可能となる。【選択図】図1
