Abstract

The invention discloses a blackboard with a metal mesher chalkrail and a vibrator, which comprises a blackboard, a metal wire mesher for filtering chalk powder and an eccentric wheel vibrator, wherein a concave chalkrail is formed at the bottom of the blackboard; the detachable metal wire mesher for placing chalks and a blackboard eraser is arranged above the concave chalkrail; and the eccentric wheel vibrator for vibrating the chalk powder is arranged at one end of the metal wire mesher by an elastic metal sheet. The blackboard has a simple structure and is convenient to operate; a switch of the eccentric wheel vibrator is turned on, the chalks and the blackboard eraser which are put on the metal wire mesher vibrate with the metal wire mesher, and the chalk powder on the chalks and the blackboard eraser drops into the concave chalkrail, so time and labor are saved, air pollution is not caused by dust, and the aim of separating the chalks, the blackboard eraser and chalk dust in time is fulfilled.
