Description

Technical Field

[0001] This utility model relates to a tape conveying device, and more particularly to a mobile tape conveying control unit and a tape conveying device. Background Technology

[0002] Various conveying equipment are used in the process of grain entering and leaving the warehouse. Mobile belt conveyors are frequently used in grain depot operations, and the height of the conveyor frame needs to be adjusted at any time according to the stacking or lowering of grain bales. This is illustrated by existing technology CN202220926523.9. Utility Model Content

[0003] This utility model addresses the problem that in existing mobile belt conveyor systems, the control switch box is located at the bottom of the conveyor, with no control switch box at the front. This results in loading and unloading personnel being too far from the existing switch box to directly control the conveyor's raising, lowering, and stopping. When adjustments or control are needed, personnel must leave their original work position, get off the grain pile or vehicle, and then climb back onto the grain pile or vehicle to continue working. Because the conveyor's height adjustment is very frequent, loading and unloading personnel are constantly climbing up and down the grain pile or vehicle. Although operating procedures are strictly followed, there are still certain safety hazards. Moreover, the accuracy of adjusting the conveyor height by personnel below is affected, and sometimes the conveyor needs to be temporarily shut down while waiting for frame adjustments. This invention provides a mobile belt conveyor control unit and belt conveyor device.
