Full-automatic cleaning blackboard

Abstract

The invention relates to a full-automatic cleaning blackboard and belongs to the technical field of education teaching instruments. A walking device is adopted to drive a cleaning device to walk on the surface of a blackboard, and then the blackboard can be cleaned; sliding tracks are arranged on the upper side and the lower side of the blackboard, and then the walking device can move conveniently; the length of the cleaning device is accordant with the width of the blackboard; and the cleaning device is large in cleaning area in cleaning operation and high in cleaning speed, in addition, full-automatic blackboard cleaning can be achieved, and the working intensity of cleaning operators can be effectively alleviated. A micro spraying device is adopted to spray water to chalk powder on theblackboard, then the chalk powder can be combined with spray droplets, the chalk powder is aggregated under the action of the spray droplets, and the chalk powder can be then effectively prevented from flying in the cleaning process; and a cleaning roller is rotated clockwise to scrape off the chalk powder from the blackboard, the scraped chalk powder is moved to a dust sucking hole of a dust collection device under the action of the cleaning roller and is further sucked into a dust storage cavity, and then the chalk powder can be prevented from being diffused into the air to pollute the environment.

Description

technical field [0001] The invention relates to a fully automatic cleaning blackboard, which belongs to the technical field of educational teaching aids. Background technique [0002] "One piece of chalk, three feet of podium", this is a sincere compliment to teachers, but they don't know that there are countless worries hidden behind these praises; there is no better education method that can replace chalk blackboard writing in the education field, but The "chalk syndrome" brought about by writing on the blackboard has become the number one potential safety hazard for teachers and students.
