Abstract

The invention relates to a blackboard, in particular to a teaching blackboard capable of automatically wiping dust. The teaching blackboard capable of automatically wiping dust is movable, capable of keeping a board surface clean and free of dust in the blackboard erasing process, and saves time and labor. In order to realize the above purposes, the teaching blackboard capable of automatically erasing dust comprises a movable blackboard body, a storage box, a sliding rail, a sliding block, a sucker, a dust collection box, an air pump, a dust sucking pipe, a motor, a bearing seat, a lead screw, a nut, an air cylinder, a supporting plate, a telescopic rod, a scroll and brushes, wherein the storage box is arranged on the left wall of the movable blackboard body; and the sliding rail is horizontally arranged in the middle of the movable blackboard body and provided with the sliding block, and the sliding block is in sliding connection with the sliding rail and provided with the sucker. The teaching blackboard capable of automatically wiping dust achieves the effects of being movable, capable of keeping the board surface clean and free of dust in the blackboard erasing process, and saving time and labor.

Description

technical field [0001] The invention relates to a blackboard, in particular to a blackboard for automatically erasing dust for teaching. Background technique [0002] The blackboard does not specifically refer to the black board surface. In the traditional sense, it is a plane that can be written repeatedly. The board surface is hard and is mostly used for teaching. Mostly black, dark green, white. [0003] The blackboard needs to be used in the teaching process. The traditional blackboard has the disadvantages of being immovable, not easy to be wiped clean, dust is easily inhaled into the lungs, affecting human health, time-consuming, and requiring a lot of manpower. Therefore, it is urgent to develop a mobile, It can keep the surface of the board clean, free from dust during the process of wiping the blackboard, save time and manpower, and is an automatic dust-erasing blackboard for teaching. Contents of the invention [0004] (1) Technical problems to be solved [00...
