Abstract
The invention relates to an English teaching blackboard. The English teaching blackboard comprises a blackboard body, wherein a frame surrounding around the edge of the blackboard body is arranged at the periphery of the blackboard body; a plurality of dust collection holes are formed in one side, close to the blackboard body, of the frame; a dust collector is arranged at the lower end of the frame; a dust collection opening of the dust collector is communicated with the interior of the frame; a motor and a gear box are arranged on each of two sides of the frame; output shafts of the two motors are connected with the gear boxes close to the motors; racks are arranged on frame bodies of the frame on two sides close to the two gear boxes; output shafts of the two gear boxes are respectively meshed and linked with the racks; a transversely-arranged strip-shaped blackboard brush is arranged on the blackboard body; two ends of the blackboard brush are fixedly connected with two racks respectively; the two racks are used for driving the blackboard brush to vertically move; the two motors are connected with a controller through a circuit; a wound point-reading panel is arranged on the frame and is connected with a host through the circuit. The English teaching blackboard can be automatically wiped and is capable of automatically collecting dust and pointing and reading English.
Description
Technical field
The present invention relates to teaching aid technical field, particularly a kind of English teaching blackboard.
Background technology
Blackboard conventional in all kinds of teaching is at present of all kinds, in every case mostly there is dust pollution question in writing on the blackboard employing chalk-writing, badly influence the healthy of teachers and students, especially in middle and primary schools, blackboard in classroom and chalk are students, the thing that teacher can touch every day, particularly when wiping board book, the dust of a sheet of white dances in the air all over the sky, everybody has inevitably sucked some chalk dusts, front-seat classmate, teacher, it is more that student on duty inhales, year in and year out, easily to the lung of students in middle and primary schools and teacher, the upper respiratory tract, eyes, skin, the many places organs such as ear work the mischief, also Other diseases can be brought out, contaminated environment.In order to solve dust pollution question and the labour intensity in order to alleviate the frequent blackboard wiping of teacher in teaching process, people have devised the manual or electric blackboard eraser of many energy automatic dust absorptions, these dust absorption blackboard erasers, all on blackboard eraser, install Small-sized suction cleaner additional to reach the object of dust suction, these dust absorption blackboard erasers, because of the reason of its structure, not only pick-up performance is unsatisfactory, and wiping is rather wasted time and energy.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of blackboard for education automatically carrying out wiping, automatically receive dust, carry out English reading.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of English teaching blackboard, comprise blackboard body, described blackboard body periphery is provided with the frame around its edge, described frame is hollow form, described frame is provided with multiple air suction opening near the side of described blackboard body, the lower end of described frame is provided with dust catcher, the suction port of described dust catcher is communicated with described frame inside, described frame both sides are provided with motor and gear-box, two described gear-boxes are in the lower end of two described motors respectively, the gear-box that the output shaft of two described motors is all close with it is connected, being provided with in described frame and close two side frame bodies of two described gear-boxes can the tooth bar of vertical movement, the meshing interlock of tooth bar that the output shaft of two described gear-boxes is close with it respectively, described blackboard body is provided with the strip blackboard brush laterally placed, the two ends of described blackboard brush are fixedly connected with two described tooth bars respectively, blackboard brush vertically movement described in two described rack drives, two described motors have controller by connection, described frame upper end framework are provided with the reading panel of winding, and described reading panel can stretch downwards and cover described blackboard body, and described reading panel has main frame by connection.
The invention has the beneficial effects as follows: dust catcher is communicated with described scuncheon, carry out by multiple air suction opening the dust adsorbing chalk; The output shaft that controller controls two motors simultaneously rotates forward, move on two motors are vertical by gearbox speed reduction band carry-over bar, controller controls the output shaft reversion of two motors simultaneously, two motors are vertically moved down by gearbox speed reduction band carry-over bar, tooth bar move on vertically with vertical folding process in all drive blackboard brush carry out on move and move down the wiping realized blackboard body, realize automatically carrying out blackboard wiping; Reading panel can stretch downwards and cover described blackboard body, and host computer control reading panel realizes read-on-command function, is convenient to teacher and realizes pronunciation of English in teaching process, promotes class-teaching of teacher efficiency, avoids teacher tired out, realize RP.
On the basis of technique scheme, the present invention can also do following improvement.
Further, two described motors be output shaft can the threephase asynchronous of rotating.
The beneficial effect of above-mentioned further scheme is adopted to be: threephase asynchronous technology maturation, Stability Analysis of Structures, effectively can extend the service life of this device.
Further, described controller is provided with can controls two described motors respectively and carry out the synchronous rotating forward button rotated and reverse and invert button.
The beneficial effect of above-mentioned further scheme is adopted to be: to rotate forward button and invert button is convenient to control motor, lifting operation convenience.
