PROBLEM TO BE SOLVED: To provide a manuring machine improved and devised so that scatter-controlling plates do not obstruct traveling during the manuring, and also dissolving the uneven amount of scattering caused by the properties of the manure, and to provide a method of manuring.SOLUTION: This manuring machine 1 is provided with a pair of the scatter-controlling plates 7a, 7b provided at supporting poles 25 each installed to stand on both sides of a scattering port 4 to be freely turnable and slidable up and down, also each of the scatter-controlling plates 7a, 7b can be fixed on each of the supporting poles 25 by an arbitrary angle and an arbitrary height, also the upper limit height of a power gate 8 moving up and down so as to be capable of opening and closing between a loading stand 3 on which the manure is loaded and a casing 5 arranged with a heater can be adjusted at an arbitrary height, and therefore, during the scattering, each of the scatter-controlling plates 7a, 7b does not obstruct the traveling and it is possible to dissolve the uneven amount of the scattering caused by the properties of the manure.COPYRIGHT: (C)2009,JPO&INPIT【課題】堆肥の散布中、散布制御板が走行の妨げにならないにように改良・工夫され、しかも、堆肥の性質によって生じる散布量のむらを解消できる堆肥散布機及び堆肥散布方法を提供する。【解決手段】本堆肥散布機1では、散布口4の両側部に夫々立設された支柱25に、回動自在及び上下摺動自在に一対の散布制御板7a、7bを設け、しかも、各散布制御板7a、7bは、各支柱25上に任意角度及び任意高さで固定でき、また、堆肥が積載される荷台3と、ビータが配置されるケーシング5との間を開閉可能に上下動するパワーゲート8は、その上限高さを任意高さに調節可能であるので、散布中、各散布制御板7a、7bが走行の妨げにならず、堆肥の性質によって生じる散布量のむらを解消することができる。【選択図】図11
