Abstract

The invention provides an automatic dusting dust-free blackboard. Blackboard erasers are arranged on the front surface of the blackboard. Magnet blocks are arranged in the positions, corresponding to the blackboard erasers, of the back surface of the blackboard. A dust collecting box and a transparent plastic plate are arranged on the lower portion of the blackboard. Rotating shafts are arranged on the two sides of the blackboard. The transparent plastic plate is connected with the rotating shafts through steel wire ropes. The periphery of the back of the blackboard is also provided with rotating shafts which are connected with the magnet blocks through steel wire ropes. By means of the structure, the rotating shafts drive the magnet blocks to move, and the blackboard erasers are attracted to move on the blackboard surface at the same time, so that the purpose of cleaning the blackboard is achieved; moreover, the rotating shafts drive the transparent plastic plate to move upwards, the effect of dust isolation is achieved, and chalk dust produced at last is accumulated and stored in the dust collecting box to be subjected to centralized processing; the harm of chalk dust produced by artificial blackboard cleaning to human health is avoided; and meanwhile, manpower is also replaced with machinery, so that the labor force is saved.

Description

technical field [0001] The invention relates to an automatic dust-removing and dust-free blackboard, in particular to an automatic dust-removing and dust-free blackboard. Background technique [0002] Existing when wiping the blackboard, because there is no good shielding, the chalk dust produced can be scattered, and the health of teachers and students is affected. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automatic dust-removing and dust-free blackboard, which uses machinery to replace the manual work of wiping the blackboard, and at the same time prevents chalk dust from flying around, which plays a great role in protecting the health of teachers and students . [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: an automatic dust-removing dust-free blackboard, a blackboard eraser is provided on the front of the blackboard, and...
