Abstract
The utility model discloses a dust sucking device for a blackboard. The device comprises a frame, wherein fixed seats are arranged on the two sides of the frame; fixing holes are formed in the fixed seats; the frame comprises two tracks; a cross beam capable of sliding along the tracks is arranged on the two tracks; a horn-shaped dust collecting box is arranged on the cross beam; the rear part of the horn-shaped dust collecting box is communicated with hoses; and the hoses are communicated with a dust sucking device body. When the dust sucking device is used, the dust sucking device body operates, and the horn-shaped dust collecting box sucks dust; in the process of erasing the blackboard, the cross beam is pushed, and the dust is sucked into the dust sucking device body; and due to the operation of the dust sucking device, the dust is prevented from scattering, and damages of the dust to teachers and students are reduced.
