Application for a patent for invention numbers 201310153790.2,2013.07.17, a kind of intelligent blackboard system is disclosed, comprise: blackboard panel, top sidewall and the bottom sidewall of blackboard panel are respectively arranged with track, are provided with tooth bar in track, in a rack and pinion engagement platform, are provided with large pinion, rack and pinion engagement platform meshes by pinion and gear wheel, and gear wheel meshes with described tooth bar again; Blackboard eraser housing, in blackboard eraser housing, be provided with dust block board, dust block board is provided with felt near a side of blackboard panel, the opposite side of dust block board is provided with motor and the shaft coupling being connected with motor, pinion is connected with shaft coupling by a little axle, and gear wheel is connected by another macro-axis by bearings.On the top sidewall of blackboard eraser housing and bottom sidewall, be provided with groove; Be arranged at the tourelle on tooth bar, on tourelle, be fixed with pin, each pin respectively with the top sidewall of blackboard eraser housing and the engagement on the sidewall of bottom.Though it can remove the font on blackboard automatically, cleanly, complex structure, manufacturing cost is high, should not promote the use of.
Summary of the invention
The present invention will provide a kind of electric blackboard eraser device, and this electric blackboard eraser is easy to use, laborsaving, can remove as required the font on blackboard, and elimination efficiency is high, simple in structure, is convenient to promote the use of.
For achieving the above object, technical scheme of the present invention is: a kind of electric blackboard eraser device, comprise blackboard eraser, guide rail, blackboard eraser cross bar, two guide rails are separately fixed at two sides of blackboard, slide block is slidably connected in guide rail, blackboard eraser cross bar is fixed on two slide blocks, blackboard eraser cross bar one side is equipped with the first motor and the first friction pulley, the first friction pulley is connected with guide rail lateral surface rolling friction contact, the first friction pulley centre bore is fixedly connected with the first motor output shaft, blackboard eraser cross bar opposite side is equipped with contact roller, contact roller rolls to contact with guide rail lateral surface and is connected, in the middle of blackboard eraser cross bar, have chute, blackboard eraser slide is slidably connected above blackboard eraser cross bar, the second friction pulley is housed in blackboard eraser slide, the second friction pulley is connected with the chute rolling friction contact in the middle of blackboard eraser cross bar, the second friction pulley is fixedly connected with the output shaft that is fixed on the second motor on blackboard eraser slide front end face, in blackboard eraser sliding base rear end portion, connect blackboard eraser.
Guide rail is T shape guide rail.Releasable connection between blackboard eraser and blackboard eraser slide.Contact roller clamping adjustment device is housed between blackboard eraser cross bar and contact roller.Blackboard lower surface is provided with ash absorbing hole, and ash absorbing hole is communicated with the suction apparatus for ash below being positioned at blackboard lower surface.
The beneficial effect that the present invention compared with prior art has is: the present invention is by motorized motions blackboard eraser cross bar and blackboard eraser slide, blackboard eraser upper and lower, left and right are moved, just required font of wiping on blackboard body etc. can be disposed cleanly, blackboard body arranges ash absorbing hole on lower surface, solved the blackboard eraser of prior art when wiping chalk word, chalk dust but flies upward everywhere, the hand of making dirty, clothes and face.And the arm technical problem of sweat that moves in turn back and forth while erasing the board, and have easy to use, laborsaving, elimination efficiency is high, the feature such as simple in structure, be convenient to promote the use of.
