Abstract

The invention provides a remote-controlled rotary automatic erasing blackboard. The blackboard comprises a blackboard driving motor, a transmission toothed belt, two circular orbits, a strip-type blackboard block, an eraser mechanism and a control box, wherein two circular orbits are arranged in longitudinal symmetry; the strip-type blackboard block is vertically arranged in orbit slots of two circular orbits; a ring of transportation toothed belt is arranged around the inner side of the strip-type blackboard block; rotating shafts are arranged at two ends in the circle of two circular orbits; a transmission gear is arranged on each rotating shaft; a driving gear is arranged on an output shaft of the blackboard driving motor; the driving gear is connected with a driven gear at the end part of the rotating shaft through the transmission toothed belt; a controller, a wireless communication module and a power source module are arranged in the control box; the controller is respectively connected with the wireless communication module and the blackboard driving motor; the erasure mechanism is used for erasing the strip-type blackboard block in a rolling way. The automatic erasing blackboard can automatically erase on the back of the blackboard, the manual erasing is omitted, and the damage of the dust to the people is lowered.

Description

technical field [0001] The invention relates to a blackboard, in particular to a remote control rotating type automatic erasing blackboard. Background technique [0002] In Chinese education and teaching, blackboards still play an important role. People still use blackboard erasers. During the process of erasing characters, chalk dust flies everywhere, which seriously affects the health of students and teachers. Although there are dust-free chalks, erasing characters The final powder is still quite serious. Therefore need to design a kind of remote control rotary automatic word erasing blackboard and just can solve the problem that chalk dust flies everywhere, also alleviates the burden of teachers erasing words simultaneously, improves class efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is that chalk dust flies around during the use of the existing blackboard. [0004] In order to solve the above-mentioned tec...
