Automatic blackboard scrubbing device applied to ideological and political education and teaching

Abstract

The invention relates to the technical field of teaching supplies and discloses an automatic blackboard scrubbing device applied to ideological and political education and teaching. The automatic blackboard scrubbing device comprises an adjusting box, wherein the adjusting box is of a hollow cuboid structure; a through groove is formed in the lower surface of the adjusting box; sliding grooves are formed in the upper surface and the lower surface of the interior of the adjusting box; the inside of each sliding groove is connected with a baffle in a sliding manner; a second motor drives a second threaded rod to rotate; a first connecting block moves forwards and backwards; when the first connecting block moves backwards, a belt is pulled to move, a second connecting block is driven to move forwards, then a supporting rod abuts against the baffles to move forwards; when the first connecting block moves forwards, the second connecting block moves backwards due to the acting force of an extension spring to drive the baffles to move backwards, then a scrubbing box is separated from the surface of a blackboard; a first motor drives a first threaded rod to rotate, so that the scrubbing box moves left and right; a third motors drives a second bevel gear to rotate, so that the second bevel gear is connected with a first bevel gear in a meshed mode; and then rotation of a shaft rod is achieved, adjusting ropes can be wound and unwound, the scrubbing box can move up and down, and blackboards can be completely scrubbed.

Description

technical field [0001] The invention relates to the technical field of teaching supplies, in particular to an automatic blackboard wiping device for ideological and political education and 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. You can use specific writing materials such as chalk to write on it. In the classroom of ideological and political education, It is often necessary to use the blackboard to write teaching content and key notes on the blackboard for students to record and watch. When the blackboard is full, it is necessary to scrub the unnecessary content for later reuse. [0003] The traditional blackboard wiper generally uses a blackboard eraser, and then the student manually holds the blackboard eraser to scrub the surface of the blackboard, but if it is used, it is ...

Problems solved by technology

[0003] The traditional blackboard wiper generally uses a blackboard eraser, and then the student manually holds the blackboard eraser to scrub the surface of the blackboard, but if it is used, it is time-consuming and labor-intensive to deal with, and because it is written with chalk, a large amount of dust is prone to drift when scrubbing, It will cause damage to the health of students or teachers, so a device for automatically scrubbing blackboards has been born on the market. At present, the devices for scrubbing blackboards on the market are generally integrated, which automatically scrubs a large area of ​​the blackboard as a whole. There is no need to scrub a large area outside of the situation, so ordinary blackboard erasers are still needed for assistance, and there are still a lot of chalk writing at present, and there will still be dust floating when scrubbing later, causing damage to the body
