And hydraulic type automatically pulled tight device is a can telescopic type belt conveying machine in the of a automatically pulled tight hydraulic system, the pulled tight device has storage with function, storage with pulled tight Shi is used manual way, in tape conveying running row, through hydraulic system automatically on conveying belt of Zhang tight force for automatically adjustment, dang rubber with tension is greater than provides value Shi, control valve down mobile, due to check valve by produced of pressure poor, liquid control valve also down mobile, makes hydraulic motor idling release rubber with, dang wear belt tension reached provides value Shi, Control valve in the middle position, automatic control valves is in the middle position, oil flow directly from the pump back to the hydraulic tank, bulging brakes brake under spring force, maintain the circular normal status so as to meet the beat.
