Abstract
The utility model relates to an automatic cleaning device that cleans of blackboard. The fixed left / right support on the wall of blackboard both sides, the last fixed left and right linear electric motor respectively of left / right support closes left and right nut respectively on left and right linear electric motor's the left and right lead screw output shaft soon, a fixed supporting beam between the left and right nut, on the supporting beam respectively an articulated left side in, the right side wipe the brush arm lower extreme, it is articulated with the connecting rod simultaneously that the upper end of brush arm is wiped on a left side in, the right side, a left side in, the right side are wiped the brush arm lower extreme and are communicated with each other with the dust catcher is sealed through a left side in, right dust pick -up hose respectively, wiping the brush arm in, to pass through the crank articulated with the carousel, and the carousel is fixed on the output shaft of worm gear motor, and the worm gear motor is fixed at a supporting beam, a left side in, the right side are wiped the face that the brush arm is relative with the blackboard and are gone up equipartition air suction opening respectively, and the air suction opening is fixed brush within a definite time. It is simple as a result, and degree of automation is high, dust pollution free.
Description
Technical field
The utility model relates to a kind of cleaning device, particularly a kind of blackboard automatic erasing cleaning device.
Background technology
Teacher often need write on blackboard, draw and explain.Often on hand, on sleeve, even hair, shoulder all leave one deck white dust after break blackboard wiping.Inevitably suck some dust simultaneously.Chalk dust is made up of gypsum, and its main chemical compositions is calcium sulfate, and the suction of chalk easily damages respiratory system, brings out breathing problem, causes lung's respiratory function to decline.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of blackboard automatic erasing cleaning device.Its result is simple, and automaticity is high, no dust pollution.
The technical scheme in the invention for solving the technical problem is: left and right support fixed by the wall of blackboard both sides, left and right linear electric motors fixed respectively by left and right support, the left and right leading screw output shaft of left and right linear electric motors screws left and right nut respectively, fixed support beam between left and right nut, difference brushing arm lower end, hinged left, center, right on brace summer, simultaneously and rod hinge connection, brushing arm lower end, left, center, right to seal with dust catcher respectively by left, center, right hose and communicates for the upper end of left, center, right brushing arm; Described middle brushing arm by crank and rotating disk hinged, rotating disk is fixed on the output shaft of worm and gear motor, and worm and gear motor is fixed on brace summer; On the face that described left, center, right brushing arm is relative with blackboard, the uniform air suction opening of difference, fixes hairbrush between air suction opening.
The utility model has following advantages: 1), adopt electric eraser to erase the board to replace tradition, reduce labour intensity, improve efficiency; 2), structure is simple, utilizes four-bar mechanism to achieve large area and cleans simultaneously, can to blackboard carry out all-dimensional multi-angle repeat clean, efficiently solve tradition and to erase the board halfway drawback; 3), be designed with dust collection mechanism, when clean, decrease flying away of dust, low-carbon environment-friendly, effectively reduce the body harm of dust to teacher and classmate; 4), convenient disassembly, easy to clean, have dust adhering to pay net in dust recycling box, take out clean; 5), can remote wireless controlled be realized, improve the continuity in classroom, decrease the secondary pollution of chalk dust to people.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is the utility model schematic diagram.
Detailed description of the invention
As shown in Figure 1, fixing left on the wall of blackboard 5 both sides, right support 2, 16, left, right support 2, fixing left respectively on 16, right linear electric motors 1, 17, left, right linear electric motors 1, a left side of 17, right leading screw output shaft 3, a left side is screwed respectively on 15, right nut 4, 14, left, right nut 4, fixed support beam 6 between 14, the hinged left side of difference on brace summer 6, in, right brushing arm 7, 11, 13 lower ends, left, in, right brushing arm 7, 11, the upper end of 13 is simultaneously hinged with connecting rod 12, left, in, right brushing arm 7, 11, 13 lower ends are respectively by a left side, in, right hose 21, 19, 18 to seal with dust catcher and communicate, described middle brushing arm 11 is hinged by crank 10 and rotating disk 9, and rotating disk 9 is fixed on the output shaft of worm and gear motor 8, and worm and gear motor 8 is fixed on brace summer 6, on the face that described left, center, right brushing arm 7,11,13 is relative with blackboard 5, the uniform air suction opening of difference (not shown in FIG.), fixes hairbrush (not shown in FIG.) between air suction opening.
Described rotating disk 9 there is the hinge hole 20 of different-diameter.Frame for movement can change the frequency of left, center, right brushing arm 7,11,13.
Left and right Linear motor remote-controlled receiver (not shown in FIG.) fixed by described left and right linear electric motors 1,17.Described worm and gear motor 8 is fixed worm and gear motor receiver of remote-control sytem (not shown in FIG.).Realize remote control.
On the base plate that the hand-held remote controller 22 of described left and right Linear motor remote-controlled receiver and worm and gear motor receiver of remote-control sytem hangs over described blackboard 5 or left and right support 2,16.
