Abstract
The utility model relates to a blackboard eraser, in particular to a device for automatically cleaning a blackboard; the blackboard eraser comprises a roller shaft arranged on the left side of the blackboard, and a bidirectional motor arranged on the upper right side of the blackboard, wherein an upper driving wheel of the roller shaft is connected with the bidirectional motor through a conveyer belt; a lower driving wheel of the roller shaft is connected with a roller wheel on the lower right side of the blackboard through a conveyer belt on the lower side of the blackboard; a disc-type hollow blackboard eraser is fixed between the upper and lower conveyer belts, the roller shaft of the disc-type blackboard eraser is fixed with a linear motor, erasing hair of the blackboard eraser is tightly attached on the front surface of the blackboard eraser, a pore communicated with the interior of the blackboard eraser is arranged on the erasing hair area of the blackboard eraser, a conduit communicated with the external environment is arranged at the bottom of the blackboard eraser, one end of the conduit is provided with a vacuum pump, and the air outlet end of the vacuum pump is connected with a mini-size air filter. The blackboard eraser can automatically clean the blackboard instead of manual labor, has high efficiency and can protect the healthy of users to the most extent.
Description
Background technology
The utility model relates to a kind of device that cleans blackboard, specifically a kind of device that can clean blackboard without manpower.
Technical field
The blackboard that existing church is used does not all have and uses the device that erases the board, if class notes in court are more, cleaning is got up slow, also teacher's health is had a strong impact in addition.
Summary of the invention
The utility model purpose is to provide a kind of blackboard device cleaner, and it has solved the deficiencies in the prior art, no longer needs manpower cleaning blackboard, and the efficient height, and the people's of the blackboard of protection cleaning to greatest extent is healthy.
Technical solution of the present utility model is on the basis of blackboard, and the utility model is provided with roller bearing particularly in the left side of blackboard, and the upper right side of blackboard is provided with either-rotation motor, and the last driven wheel of roller bearing links to each other by conveyer belt with either-rotation motor; The following driven wheel of roller bearing links to each other with the roller of blackboard lower right side by the conveyer belt of blackboard downside; There is the collar plate shape blackboard eraser to be fixed between the upper and lower conveyer belt, roller bearing is fixed with linear electric motors on the blackboard eraser of collar plate shape, the blackboard front surface is close in the snag of blackboard eraser, the snag district of blackboard eraser has and the inner hole that communicates, the conduit that links to each other with the outside is arranged at the bottom of blackboard eraser, one end of conduit is provided with vavuum pump, and the outlet side of vavuum pump is connected with micro air filter.
More than described in the utility modelly have two blackboard erasers to be fixed between the upper and lower conveyer belt.
Conveyer belt described in the utility model is that chain transmits.
Operation principle of the present utility model is: the either-rotation motor of opening blackboard can make conveyer belt drive blackboard eraser to moving on one side, the collar plate shape blackboard eraser is also rotation under the drive of linear electric motors, at this moment the snag of blackboard eraser can be cleaned the chalk dust on blackboard surface, in the cleaning blackboard, because the vavuum pump suction air can siphon away chalk dust, is connected with micro air filter in the outlet side of vavuum pump, chalk dust can all be absorbed, and can not cause secondary pollution.
The utility model advantage is: no longer need manpower cleaning blackboard, and the efficient height, the people's of the blackboard of protection cleaning to greatest extent is healthy.
