PROBLEM TO BE SOLVED: To solve a problem that attaching and detaching operations are troublesome since a hopper is mounted by fixing tools at four parts.SOLUTION: The seeding device is detachably configured to include a seed feed hopper 53 of a seed feeder 50 for feeding seeds to a seeding-raising container A. The seed feed hopper 53 has a lower part that is formed by a front guide plate 55 and a rear guide plate 56 in a funnel shape in a side view. Side plates 60 at both right and left sides of the seed feed hopper 53 are equipped with a pair of right and left side-projecting engagement pins 61, respectively. The engagement pins 61 are detachably engaged with engagement grooves 62 of side plates 52 of a frame 51 of the seed feeder 50 from above. The front guide plate 55 includes a lower projecting mounting shaft 63 which is inserted into an insertion hole 65 of a front inclined plate 64 attached to the side plates 52 and to which a fixed dial 66 mounted on the lower surface side of the front inclined plate 64 is screwed.COPYRIGHT: (C)2012,JPO&INPIT【課題】ホッパーを四カ所の固定具で取り付けていたので、着脱作業が面倒であった。【解決手段】育苗容器Aに種子を供給する種子供給装置50の種子供給ホッパー53を着脱自在に設ける。種子供給ホッパー53は、その下部を前側誘導板55と後側誘導板56とにより側面視漏斗状に形成する。種子供給ホッパー53の左右両側の側板60には側方に突出する左右一対の係合ピン61を夫々設け、該係合ピン61は種子供給装置50のフレーム51の側板52の係合溝62に上方より着脱自在に係合させる構成とし、前記前側誘導板55には、前記側板52に設けた前側傾斜板64の挿通孔65に挿通して、前記前側傾斜板64の下面側に設けた固定ダイヤル66を螺合させる、下方に突出する取付軸63を設けた播種装置。【選択図】図14
