Title: Grain feeder for grain drier
Inventor: NISHINO EIJI
IPC: F26B25/00
Filed: 1994-02-23
Abstract: PURPOSE:To reduce noise during a drying operation of grain at night. CONSTITUTION:At the time of a drying operation of grain, the grain is carried and fed onto a diffusing board 24 which is driven to rotate so that the grain is diffused and fed into a grain storage chamber. However, at the time of a drying operation at night, the rotation and driving of the diffusing board 24 is stopped by operating a switching device 26' to drop the grain directly to the storage chamber from the diffusing board 24. Thus, during the drying operation at night, the grain does not directly collide with the inner wall part of a frame wall forming the storage chamber. As a result, noise generated from the grain colliding with the frame wall can be prevented, which contributes to a quiet drying operation.
