PROBLEM TO BE SOLVED: To provide a new chaff-spreading technique capable of preventing the bridging phenomena of chaffs one another in a container and also capable of smoothly making the operation of opening a spreading port.SOLUTION: The chaff spreader 1 is such that: there are a skeletal form 10 and a container part 5 front and rear two spreading ports 21 are opened on the skeletal form 10 the respective spreading ports 21 and 21 are fitted with openable lids 4 and 4 so that their basal ends 40 and 40 are axially fitted on the front respective rims 22 and 22 of the ports 21 and 21, and the respective turning ends 41 and 41 opposite to the corresponding respective basal ends 40 and 40 are fitted so as to respectively butted on the rear rims 23 and 23 of the respective spreading ports 21 and 21 and to be closable the ceiling postures of the respective openable lids 4 and 4 under closed conditions are set up inclinedly, rather than horizontally, so as to form slight downward gradient from the basal ends 40 and 40 toward the turnable ends 41 and 41, and appropriate positions of the respective openable lids 4 and 4 are incorporated with a conjunctive mechanism 6 and an opening/closing mechanism 7.COPYRIGHT: (C)2010,JPO&INPIT【課題】コンテナー部内の籾殻同士のブリッジ現象を未然に防止することができると共に、散布口の開放操作を軽快に行うことができる新たな籾殻散布技術を提供する。【解決手段】走行車両に連結可能な骨格体10とコンテナー部5とを有し、該骨格体10に前後2個の散布口21を開口し、各散布口21,21に開閉蓋4,4を、それらの基端40,40が、夫々各散布口21,21の前縁22,22に軸着されると共に、各基端40,40とは反対がわの各回動端41,41が夫々、各散布口21,21後縁23,23に夫々当接して閉鎖可能とするよう装着し、閉鎖状態の各開閉蓋4,4天面姿勢を、夫々水平姿勢とはせず、基端40,40から回動端41,41に向けて僅かな下り勾配とするよう傾斜状配置で据え付けた上、各開閉蓋4,4の適所に連動機構6および開閉操作機構7を組み込んでなる籾殻散布装置1である。【選択図】図1
