PROBLEM TO BE SOLVED: To provide a grain dispensing device hardly forming a gap between a grain dispensing port and an dispensing changeover member, and preventing leakage of grains even when the position of the dispensing changeover member is bent slightly downward.SOLUTION: The dispensing changeover member 90 is composed so as to freely shake and change over to an dispensing-permitting posture for opening the grain dispensing port 15 and an dispensing-preventing posture directed upward from the dispensing-permitting posture to close the grain dispensing port 15. Surface parts 51 and 90a are provided on the inner surface of the grain dispensing port 15 and at the end of the dispensing changeover member 90, and are configured so that the surface part 51 of the grain dispensing port 15 comes into surface contact with the surface part 90a of the dispensing changeover member in the dispensing-preventing posture to prevent the dispensing of the grains from the grain dispensing port 15.COPYRIGHT: (C)2011,JPO&INPIT【課題】排出切換部材の位置が多少下向きに撓んでも、穀粒排出口と排出切換部材との間に隙間が生じ難くして、穀粒漏れを防止する穀粒排出装置を提供する点にある。【解決手段】排出切換部材90を、穀粒排出口15を開放する排出許容姿勢と、排出許容姿勢よりも上向きで穀粒排出口15を閉鎖する排出阻止姿勢とに揺動切換自在に構成する。穀粒排出口15の内面及び排出切換部材90の端部に面部51,90aを設け、排出阻止姿勢において穀粒排出口15の面部51と排出切換部材の面部90aとが面接触して、穀粒排出口15からの穀粒の排出を阻止するように構成してある。【選択図】図5
