To achieve these goals, the technical solution of the utility model is as follows:
Automatic blackboard eraser, comprise across be arranged on the guide rail that bar shaped on the blackboard is wiped head, is arranged on the blackboard edge, bar shaped is wiped head and is provided with the bristle that is used to erase the board, and bar shaped is wiped a back side and is provided with dismountable dust-absorbing box, and bar shaped is wiped cephalic par and be provided with the pulley that can slide on guide rail.
Described pulley is connected with the drive motors of its rotation of driving.
Described bar shaped is wiped head and is provided with the elastic device that makes snag be close to blackboard.
The beneficial effects of the utility model are, make blackboard eraser bar move left and right blackboard wiping by guide rail, can effectively wipe the chalk trace on the blackboard, when erasing the board, can not cause flying upward of chalk powder everywhere, therefore can reduce the generation of environmental pollution and disease.Owing to be not directly to go to erase the board, also can reach effect of saving time and labor with hand.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the structural representation of an embodiment of the utility model.
The label declaration of parts in the schematic diagram:
2 pulleys, 3 motor, 4 guide rails, 5 switches, 6 blackboard is wiped in 1 bar shaped
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, automatic blackboard eraser comprises that bar shaped wipes 1, guide rail 4, pulley 2, motor 3 and switch 5, rolls about pulley 2 is fixed on the guide rail 4, and motor 3 is connected the control device of control pulley 2 automatic reverses rolling with switch 5 circuit.Bar shaped is wiped 1 and is provided with snag, wipes a back side and is provided with dismountable dust-absorbing box, and circuit connects switch 5.Bar shaped is wiped 1 and is provided with the elastic device that makes snag be close to blackboard 6, as spring.After opening switch 5, motor 3 rotates, and drive pulley 2 is rolled along guide rail 4 left and right directions, and an end that at every turn is rolled into blackboard 6 will be controlled its commutation rolling automatically by control device, and bar shaped wiping head just can move around the wiped clean blackboard like this.Dust-absorbing box sucks chalk powder in the box simultaneously, just can prevent that chalk powder from flying upward everywhere, influences academics and students's health.
