Problem to be solved: to obtain a low cost in a powder particle spraying apparatus provided with a feed supplying portion which is connected to the lower portion of the granular tank to transfer the powdery substance from the granular material tank and diffusing the powdered granular material in the right and left directions behind the work machine and supply it to the field.Delivery delivery case 40 isA feed supply case 43 for accommodating a feed supplying member 48 for feeding a powder granule from the granular tank 30A andA left scattering case 46 which houses the left scattering member 55 for scattering the powder particles in the left direction andA right scattering case 47 which houses the right scattering member 56 for scattering the powder particles to the right direction and theDelivery feed member 48A driving mechanism case 44 for accommodating an electric drive mechanism 45 for outputting power to the left scattering member 55 and the right scattering member 56 and the like.Diagram【課題】粉粒体タンクの下部に接続されて、粉粒体タンクから粉粒体を繰り出し、繰り出した粉粒体を作業機の後方で左右向きに拡散させて圃場に供給する繰出し供給部が備えられた粉粒体散布装置において、安価に得ることを可能にする。【解決手段】繰出し供給ケース４０は、粉粒体タンク３０Ａから粉粒体を繰出す繰出し供給部材４８を収容する繰出し供給ケース部４３と、粉粒体を左向きに飛散させる左飛散部材５５を収容する左散布ケース部４６と、粉粒体を右向きに飛散させる右飛散部材５６を収容する右散布ケース部４７と、繰出し供給部材４８、左飛散部材５５及び右飛散部材５６に向けて動力を出力する電気原動機構４５を収容する原動機構ケース部４４と、に分割可能である。【選択図】図８
