the controller is connected with each electric telescopic rod through a control line to control the operation of the wiping unit.
Preferably, the controller adopts a single chip microcomputer.
Preferably, the controller adopts remote control, when carrying out the wiping operation to the teaching board, can stand in the place of keeping away and start, avoids the dust injury.
The beneficial effects of the utility model reside in that: in the literature teaching, the original blackboard writing content can be erased locally and integrally quickly and flexibly, the teaching progress can be smoothly performed, the erased chalk powder is collected, and the chalk powder is prevented from flying around; specifically, each wiping unit is responsible for wiping a part of the area of the teaching board, when a part of the teaching board needs to be wiped, only the wiping unit of the part needs to be started, when the whole teaching board is wiped, all the wiping units are started, and the teaching board is wiped cleanly at one time; one part of the scraped dust falls into the board groove, and the other part of the scraped dust is directly pushed into the dust separation cavity along with the scraping block and falls into the bottom of the powder collection box; the board groove communicates the dust to break away from the chamber, pushes the dust in the board groove to break away from the chamber, and the dust is cleared away from the blow-down door after accumulating a certain amount.
Further, in order to make dust propelling movement to the dust break away from the chamber after can freely fall into the powder and collect the box bottom, the dust breaks away from the preceding low of lateral wall ratio teaching board behind the chamber, wipes the piece like this and gets into the dust and breaks away from the chamber after, just no longer contacts the teaching board before, the dust directly drops.
Furthermore, gland nut can follow the connecting rod and reciprocate, drives and adjusts the clamp plate and keeps away from or be close to the teaching board, is convenient for like this change clean the piece and adjust the frictional force of cleaning between piece and the teaching board, and then control cleans the effect.
