Abstract
The utility model relates to an improvement of a blackboard eraser structure, and provides to a motor-driven blackboard eraser which is stable in running and convenient to control. The motor-driven blackboard eraser comprises a frame, and is characterized in that a driving shaft is arranged at the upper end of the frame, and a driven shaft is arranged at the lower end of the frame. Chain wheels are respectively arranged at two ends of the driving shaft and two ends of the driven shaft. The upper group of chain wheels and the lower group of chain wheels are connected through chains, a transverse plate is arranged between two chains, and cotton cloth is wrapped on the transverse plate. A water storage box is arranged at the upper end of the transverse plate, and a water inlet and a water outlet are arranged on the water storage box. A leakage-proof cover is arranged on the position of the water inlet and connected with the water storage box through threads. The water outlet is connected with the cotton cloth through a water injection pipe, and a water stop clamp is arranged on the water injection pipe. The driving shaft is connected with a motor on the upper portion of the frame, and the motor is connected with a motor control box under the motor.
