PROBLEM TO BE SOLVED: To provide a granular material spraying apparatus that can stably supply granular materials in a hopper to a delivery unit.SOLUTION: A sowing device 3 being a granular material spraying apparatus includes a hopper 30 for receiving seed, a feeding unit 50 for feeding the seed, and a transfer path unit 40 having a guide passage 43 for guiding the seed in the hopper 30 to the feeding unit 50. The guide passage 43 has an expansion passage unit 43a being brought into communication with the hopper 30 and having a passage area B increased as going to the downstream side of a seed guiding direction A from a communication part with the hopper 30.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2017,JPO&INPIT【課題】ホッパ内の粒状体を繰出部に安定的に供給することが可能な粒状体散布装置を提供する。【解決手段】粒状体散布装置である播種装置3は、種子を収容するホッパ30と、種子を繰り出す繰出部50と、ホッパ30内の種子を繰出部50へと案内する案内通路43を有する移送経路部40と、を備え、案内通路43は、ホッパ30に連通されると共にホッパ30との連通部から種子の案内方向Aの下流側に向かうに従って通路面積Bが大きくなる拡大通路部43aを有する。【選択図】図4
