It passes through the Lee shutter 13 and falls into the take-out tank 4, but at that time it is taken out from the ventilation frame 11. Due to the suction and exhaust air directed toward the tank 4, some straw waste and dust are removed through the air exhaust cylinder 10 due to the wind selection effect. and is ejected from the aircraft. The grains, straw waste, dust, etc. that have fallen to the bottom of the take-out tank 4 are removed by the take-out screw 14. The grains are transferred to the lower part of the grain lifting machine 5, pumped up into the bucket 17, and passed through the upper throwing port 19. It is put into the storage tank 2. At this time, the straw, dust, etc. mixed in the grains have a relatively lighter specific gravity than the grains, so Most of it falls onto the dust collector 21 provided below the grain input port 20. Also dust collection Some of the grains that have passed above the disk 21 collide with the grain return guide plate 23 and are collected by the dust collector 21. fall on top. The straw, dust, and a small amount of grain that have fallen onto the dust collector 21 are sent to the return passage 22 for frying. It flows into the lowering side of the bucket of machine 5 and falls to the bottom of grain lifting machine 5, near the grain export port 15. In this case, the filter is subjected to a wind selection action by the selection air generated by the suction action of the exhaust fan 9. Then, the straw and dust pass through the take-out tank 4 and are discharged from the exhaust barrel 10 to the outside of the machine. After being subjected to the wind sorting action, the grains that have fallen to the bottom of the grain lifting machine 5 are transported by the unloading screw 14. The mixture is mixed with the grains that have been transferred, and then pumped up again into the bucket 17 and sent to the upper throwing port 1. 9 and is put into the storage tank 2.

本考案は以上の通り構成されているので、穀粒乾燥作業中に穀粒中に混入して いる藁屑や塵埃などが貯留槽の穀粒投入口近傍に集中して堆積されるのを防止し て、穀粒の流下を円滑にし乾燥むらを防止すると共に、藁屑や塵埃を効率よく取 り除き機外に排出し、且つその性能が安定していて藁屑などが詰まることの無い 排塵装置を備えた穀粒乾燥機を安価に提供できるものである。 Since the present invention is constructed as described above, it is possible to avoid contamination with grains during the grain drying process. This prevents straw waste and dust from concentrating and accumulating near the grain input port of the storage tank. This allows the grain to flow smoothly and prevent uneven drying, while also efficiently removing straw and dust. It removes straw waste and discharges it outside the machine, and its performance is stable and does not get clogged with straw waste. A grain dryer equipped with a dust removal device can be provided at a low cost.

【０００９】 以上のように構成した実施例のものにおいて乾燥作業中、貯留槽２に収容され た穀粒及び穀粒中に混入した藁屑や塵埃などは、穀粒流下路１２を流下しロータ リーシャッタ１３を通過して取出槽４に落下するが、その際排風枠１１から取出 槽４へ向かう吸引排風により風選作用を受け一部の藁屑、塵埃は排風胴１０を通 過して機外に排出される。 取出槽４底部に落下した穀粒及び藁屑、塵埃などは搬出スクリュー１４により 揚穀機５下部に移送されバケット１７に汲み上げられ上部投擲口１９を通過して 貯留槽２内に投入される。 この時、穀粒中に混在する藁屑、塵埃などは穀粒よりも比較的比重が軽いので その多くは穀粒投入口２０の下方に設けられた集塵盤２１上に落下する。又集塵 盤２１の上方を通過した穀粒の一部は穀粒戻し案内板２３に衝突して集塵盤２１ 上に落下する。 集塵盤２１上に落下した藁屑や塵埃及び少量の穀粒は戻り通路２２を経て揚穀 機５のバケット下降側に流入して、揚穀機５下部まで落下し穀粒搬出口１５付近 において、排気ファン９の吸引作用により起成される選別風により風選作用を受 けて、藁屑や塵埃は取出槽４内を通過して排風胴１０より機外に排出される。 風選作用を受けた後、揚穀機５底部に落下した穀粒は搬出スクリュー１４によ り移送されてきた穀粒と混合して再びバケット１７に汲み上げられ上部投擲口１ ９を通過して貯留槽２内に投入される。[0009] In the embodiment configured as described above, during the drying operation, the water is stored in the storage tank 2. The grains and the straw and dust mixed in the grains flow down the grain flow path 12 and reach the rotor. It passes through the Lee shutter 13 and falls into the take-out tank 4, but at that time it is taken out from the ventilation frame 11. Due to the suction and exhaust air directed toward the tank 4, some straw waste and dust are removed through the air exhaust cylinder 10 due to the wind selection effect. and is ejected from the aircraft. The grains, straw waste, dust, etc. that have fallen to the bottom of the take-out tank 4 are removed by the take-out screw 14. The grains are transferred to the lower part of the grain lifting machine 5, pumped up into the bucket 17, and passed through the upper throwing port 19. It is put into the storage tank 2. At this time, the straw, dust, etc. mixed in the grains have a relatively lighter specific gravity than the grains, so Most of it falls onto the dust collector 21 provided below the grain input port 20. Also dust collection Some of the grains that have passed above the disk 21 collide with the grain return guide plate 23 and are collected by the dust collector 21. fall on top. The straw, dust, and a small amount of grain that have fallen onto the dust collector 21 are sent to the return passage 22 for frying. It flows into the lowering side of the bucket of machine 5 and falls to the bottom of grain lifting machine 5, near the grain export port 15. In this case, the filter is subjected to a wind selection action by the selection air generated by the suction action of the exhaust fan 9. Then, the straw and dust pass through the take-out tank 4 and are discharged from the exhaust barrel 10 to the outside of the machine. After being subjected to the wind sorting action, the grains that have fallen to the bottom of the grain lifting machine 5 are transported by the unloading screw 14. The mixture is mixed with the grains that have been transferred, and then pumped up again into the bucket 17 and sent to the upper throwing port 1. 9 and is put into the storage tank 2.

本考案は以上の通り構成されているので、穀粒乾燥作業中に穀粒中に混入して いる藁屑や塵埃などが貯留槽の穀粒投入口近傍に集中して堆積されるのを防止し て、穀粒の流下を円滑にし乾燥むらを防止すると共に、藁屑や塵埃を効率よく取 り除き機外に排出し、且つその性能が安定していて藁屑などが詰まることの無い 排塵装置を備えた穀粒乾燥機を安価に提供できるものである。 Since the present invention is constructed as described above, it is possible to avoid contamination with grains during the grain drying process. This prevents straw waste and dust from concentrating and accumulating near the grain input port of the storage tank. This allows the grain to flow smoothly and prevent uneven drying, while also efficiently removing straw and dust. It removes straw waste and discharges it outside the machine, and its performance is stable and does not get clogged with straw waste. A grain dryer equipped with a dust removal device can be provided at a low cost.
