Abstract
The utility model discloses an automatic blackboard erasing device. The automatic blackboard erasing device comprises a first micro motor and a second micro motor. The first micro motor is connected with a first belt pulley through a first belt. The second micro motor is connected with a second belt pulley through a second belt. The first belt pulley and the second belt pulley are arranged along the other diagonal line of a blackboard. A cotton sliver fixing device is fixedly connected between the first belt and the second belt and provided with cotton slivers, a dust collecting box is connected to the lower end of the cotton sliver fixing device, and a vibration device is installed inside the dust collecting box. The first micro motor, the second micro motor and the vibration device are respectively provided with a controller, and the controllers are connected with a remote control in a signal mode. The remote control controls work of the first micro motor and the second micro motor for driving the cotton sliver fixing device and the cotton slivers to move back and forth on the blackboard, and therefore chalk marks on the blackboard are erased. The automatic blackboard erasing device is simple in structure, convenient to use and beneficial for protecting air quality of a classroom, thereby protecting physical health of teachers and students.
