Main technical schemes of the present utility model is: it comprises by blackboard body, blackboard surface and forming, described blackboard surface is a closed circulation structure, be installed on the transmission mechanism being formed by top driven shaft and bottom driving shaft, upper lower rotary shaft is all installed on blackboard body, bottom driving shaft is by the electric-motor drive that is arranged on blackboard body one side, and its opposite side axle head is also provided with turning handle; The blackboard surface that is provided with above at blackboard body is imported and exported, while is provided with bristle rotating shaft at the rear of driving shaft, bottom is provided with disposal box, described bristle rotating shaft is the cylinder axis that surface is provided with intensive bristle, the two ends of axle are installed on blackboard body by bearing, transmission device by Motor Control drives, and the bottom of disposal box is provided with dust mouth; The below of blackboard body is also provided with and hangs the link that small blackboard is wiped.The back side of blackboard surface is provided with anti-skidding ripple, and below the driving shaft in disposal box and the rear of bristle rotating shaft is all provided with dust dividing plate.
The utility model is not only simple in structure, simple for production, easy operating, and can be disposable writing on whole blackboard surface be removed clean, and also can utilize small electric blackboard eraser to remove local word on blackboard surface, can help preferably numerous students in middle and primary schools to do blackboard wiping time on duty for the day.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the utility model overall structure schematic diagram;
Fig. 2 is the utility model cross section structure schematic diagram.
In figure: 1 is blackboard body, 2 for importing and exporting, and 3 is blackboard surface, and 4 is driving shaft, and 5 is driven shaft, and 6 is bristle rotating shaft, and 7 is motor, and 8 is disposal box, and 9 is handle, and 10 wipe for small blackboard, and 11 is bristle, and 12 is dust dividing plate.
The specific embodiment
As shown in the figure, get metal or wood materials and make the blackboard body 1 of cuboid, get soft material and make annular blackboard surface 3, get two round steel and make rotating shaft, wherein to be placed in the top of blackboard body 1 be driven shaft 5 at the two ends of, and the bottom that another root is installed on blackboard body 1 is driving shaft 4, and blackboard surface 3 is placed on upper and lower main driven shaft, driving shaft 4 is connected with motor machine 7 by driving-belt, by switch control.Simultaneously the rear of the driving shaft 4 of blackboard surface 3 be provided with bristle rotating shaft 6, below disposal box 8 is set, described bristle rotating shaft 6 is the surperficial cylinder axis that intensive bristle 11 is set, the two ends of axle are installed on blackboard body 1 by bearing, controlling transmission mechanism by motor 7 drives, blackboard body 8 is fixed on body of wall, and the bottom of disposal box 8 is provided with dust mouth.Blackboard body 1 below be also provided with the link that hangs small blackboard brush 10.In order to prevent skidding, the back side of blackboard surface 3 is set to ripple, and is provided with dust dividing plate 12 with the rear of bristle rotating shaft 6 below driving shaft 4.While implementing the utility model, be a teacher complete by being presented on blackboard body 1 blackboard surface 3 writings on the blackboard above, only need press the power switch of motor, transmission mechanism drives driving shaft 4, driven shaft 5 and hairbrush rotating shaft 6 to rotate, write character segment and involved in blackboard body 1, the writing retransferring to blackboard body 1 blackboard surface 3 above is carried out new round writing on the blackboard by the clean clean teacher of confession of the bristle in bristle rotating shaft 6, is automatically dropped to 8 li of disposal boxes by the chalk powder under wiping.In the time that dust is accumulated to a certain degree, disposal box 8 bottom deslagging mouths can be opened, remove dust in case.When all information that do not need to wipe on blackboard surface 1, while only needing local change, only need hold small blackboard brush 10 and take off in the link of blackboard body 1 bottom, being faced toward the writing that will change can revise, thereby has greatly reduced the healthy of the dust pollution in classroom and infringement teachers and students.
