The invention discloses a vehicle-mounted magnetic force augmentation station for a belt conveyor. The vehicle-mounted magnetic force augmentation station comprises a machine frame arranged on a foundation; a driving device and a machine tail tensioning device are disposed on the front portion and the rear portion of the machine frame correspondingly; an upper guide way and a lower guide way are disposed on the linear section of the machine frame; a head guide way is mounted in front of the machine frame; a tail guide way is disposed in rear of the machine frame; supporting legs are disposed at the bottom of the machine frame at intervals and provided with lower carrier rollers; wheels of a plurality of magnetic steel trolleys are arranged on the linear-section upper guide way, the linear-section lower guide way, the head guide way and the tail guide way and are in end-to-end connection with one another in sequence through connecting pins; trolley frames are fixed to axles of the wheels; magnetic steel is fixed to the trolley frames; partition boards are arranged on the upper portions of the magnetic steel; and a force augmentation station adhesive tape is wound through a roller on the driving device, penetrates through the upper portions of the magnetic steel trolleys arranged on the linear-section upper guide way and through the upper portions of the lower carrier rollers and is wound through a roller on the machine tail tensioning device to be in closed connection, and a main machine adhesive tape body is arranged on the upper surface of the force augmentation station adhesive tape. By means of the vehicle-mounted magnetic force augmentation station for the belt conveyor, the effects that the mechanism is compact, the driving force is high, operation is reliable, safe and stable, maintaining is simple and convenient, pollution is avoided, and the frictional power loss is avoided are achieved.
