Abstract

PURPOSE:To eliminate husking dry grains with much of mixture of green grains or immature grains and increase husking efficiency by installing a selector, a husker and a diverging device to be switched over freely to discharging out of the machine on a grain discharge section of a grain dryer. CONSTITUTION:Grains dried in a drying chamber 1 of a grain dryer 2 are conveyed to a transfer conduit 16 through a grain lifter 30 and a discharge cylinder 33, and then discharged into a selector 4 or into a husker 5 or else directly discharged outside a device. When a number of green grains or immature grains are mixed therein, an upper section diverging tube 21 of a diverging device 6 is connected with the selector 4, and the green grains and immature grains are selected in the selector 4, and selected grains are discharged directly outside the device or discharged into the husker 5 and the selected grains are husked by the husker 5. When the mixture of green grains and immature grains is small in quantity, the upper section diverging tube 21 and a lower section diverging tube 24 of the diverging device 6 are connected with the husker 5 and the grains are husked by the husker 5. When husking is not carried out by the husker 5, the grains are discharged directly out of the device from the lower section diverging tube 24 of the diverging device 6 through a dry discharge cylinder 28.
