Abstract
The utility model relates to a blackboard eraser, in particular to a device for automatically cleaning a blackboard; the blackboard eraser comprises a bidirectional motor arranged on the upper right side of the blackboard, wherein an upper driving wheel of a 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 roller-type blackboard eraser is fixed between the upper and lower conveyer belts, the roller shaft of the roller-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. 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; Have the roller type 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 roller type, and the blackboard front surface is close in the snag of blackboard eraser.
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, roller type blackboard eraser also counter-rotation under the drive of linear electric motors, the snag of blackboard eraser at this moment can be cleaned the chalk dust on blackboard surface.
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.
Description of drawings
Fig. 1 is an organigram of the present utility model;
The specific embodiment
According to shown in Figure 1, the utility model is on the basis of blackboard 1, the utility model is provided with roller bearing 2 particularly in the left side of blackboard 1, the upper right side of blackboard 1 is provided with either-rotation motor 4, and the last driven wheel of roller bearing 2 links to each other by conveyer belt 3 with the SD-205 type either-rotation motor 4 of Shenzhen speed Deco skill Co., Ltd; The following driven wheel of roller bearing 2 links to each other with the roller of blackboard 1 lower right side by the conveyer belt of blackboard 1 downside; Have roller type blackboard eraser 5 to be fixed between the upper and lower conveyer belt, roller bearing is fixed with the Dongguan City rain field YT of Electric Machine Co., Ltd type linear electric motors 7 on the blackboard eraser 5 of roller type, and the blackboard front surface is close in the snag 6 of blackboard eraser 5.
