<p>A bucket elevator-type continuous unloader (1) is provided with a bucket elevator (9) for continuously conveying bulk material (M). The bucket elevator (9) is provided with: buckets (27) for scooping and loading the bulk material (M); a chain (25) for holding the buckets (27); a load motor (75) for driving and circulating the chain (25); an inverter (73) for detecting a load on the load motor (75); and a PLC (80) which, when a value based on the load detected by the inverter (73) is less than or equal to a set value (A), controls the load motor (75) and reduces the movement speed of the buckets (27) to a speed lower than the speed of a case where the value based on the load is greater than the set value (A).</p> |
