Abstract

The invention belongs to the technical field of teaching equipment, and discloses a dustless blackboard. A panel transmission mechanism is provided; a first motor is arranged on the panel transmissionmechanism, is positioned above the panel transmission mechanism, and is connected with a main roller through a first bearing; the main roller is connected with a driven roller through a tooth-shapedbelt; a back cover erasing mechanism is provided with a second motor; the second motor is positioned on the right upper side of a back box cover of the back cover erasing mechanism; the second motor is connected with a thread guide rod through a tooth-shaped belt; an erasing board sleeves the thread guide rod through a thread; and a polish guide rod sleeves the erasing board. When writing on the board is finished, and teachers start the motors, automatic erasing of the writing on the blackboard can be realized; and the dustless blackboard achieves no influence on teaching by the teachers in the writing erasing process and no dust flying.

Description

technical field [0001] The invention belongs to the technical field of teaching equipment, in particular to a dust-free blackboard. Background technique [0002] The traditional automatic blackboard design is to design the automatic wiping board in front of the blackboard, and then use the power supply and some mechanisms to wipe the blackboard clean. The disadvantage of this automatic blackboard is that the dust is flying around during the wiping process, and there is no treatment for the dust. , and can not continue to write on the blackboard because of the moving teacher of wiping board or the student in wiping process, so for the consideration of these two points the present invention optimizes it, need to design no dust blackboard. [0003] In summary, the problems in the prior art are: [0004] During the traditional automatic blackboard wiping process, the dust is flying everywhere, and the dust is not treated, and the teacher or students cannot continue to write on ...
