METHOD AND DEVICE FOR OPERATION OF GRAIN DISCHARGING INSTRUMENT IN GRAIN DRYING AND STORAGE DEVICE

摘要

PROBLEM TO BE SOLVED: To permit the achievement of discharging of grain at a low cost without generating any interrupted condition of discharging of the grain during switching when the operation of respective discharging instruments for a plurality of discharging units are controlled so as to be switched sequentially without employing a sensor for detecting the flowing condition of the grain. ;SOLUTION: When the grain, accumulated on a floor plate, is discharged out of a discharging port communicated with the discharging instrument by the operation of discharging instruments, a period of time until forming a slanted surface arrived at an angle of repose of the grain which flows down toward the discharging port is obtained by an operation from the accumulating height of the grain with respect to respective discharging ports or an experimental value. The preset discharging period of times are set by allotting the same to respective discharging instruments so that the finishing time point of the preset discharging period of time for operating one discharging instrument is lapped with the starting time point of preset discharging period of time of another discharging instrument operated by next order or occupies a timing with a slight time difference. The grain is discharged by switching the operation of respective discharging instruments automatically and sequentially in accordance with the preset discharging period of time.;COPYRIGHT: (C)2001,JPO
