Description
Technical field
The utility model belongs to blackboard eraser field, particularly a kind of automatic blackboard eraser.
Background technology
In daily life at ordinary times.When writing on the blackboard amount is larger, manually erases the board and waste time and energy, greatly reduce efficiency of giving lessons.According to the deficiency of existing blackboard eraser, use electromechanical integration technology, design a new type auto blackboard cleaning device.By the installation of this money automatic blackboard eraser, can overcome the above problems completely.Teacher and classmate after a button pressed, can proceed other education activities completely, automatically that blackboard eraser is clean by machine.So both do not worry that blackboard dust is also time saving and energy saving and also improve classroom efficiency simultaneously, and the enthusiasm of attending class of classmates.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of automatic blackboard eraser.
Technical solution of the present utility model: a kind automatic blackboard eraser, comprises blackboard eraser motion, blackboard eraser transverse moving mechanism, blackboard eraser lifting mechanism, control section; Described blackboard eraser motion is made up of crank rocker transmission mechanism; Described blackboard eraser transverse moving mechanism is made up of electric wire rope pulling mechanism; Described blackboard eraser lifting mechanism inhales drawing device as power by electromagnetism; Described control section controls mechanical part by the switch of each motor of No. four remote controller Long-distance Control.
Further, the feature of described blackboard eraser motor pattern is, two blackboard erasers do fan-shaped swing as vehicle wiper.Erasing area is larger.This device drives crank and rocker mechanism to realize fan-shaped oscillating motion by blackboard eraser by motor.
Further, what described blackboard eraser transverse shifting adopted is by electric capstan folding and unfolding steel wire rope, and pulls the movable floor installing whole blackboard eraser motion to move by steel wire rope, thus realizes the transverse shifting of blackboard eraser.The movable floor installing blackboard eraser motion is by two guide rails assemblings on whole automatic blackboard eraser framework, and electric wire rope capstan winch is fixed thereon, and steel wire rope is connected with movable floor by two pulleys being arranged on automatic blackboard eraser framework.
Further, the lifting mechanism running of described blackboard eraser is inhaled drawing device by electromagnetism and is realized, its running produces magnetic after being energized by solenoid to be inhaled by iron core dynamic, by pull bar with rotate torque arm and pull rotate to an angle installing the support baseboard rotating shaft of blackboard eraser, thus realize blackboard eraser and lift (not wiping).
Further, described control section consists of Control 2 motor and an electromagnetism suction drawing device four tunnels control remote controllers.
beneficial effect:
Compared with prior art, of the present utility model have a key automatic blackboard cleaning, away from dust harzard.Than like product more rapidly and efficiently, time saving and energy saving.Intellectuality, can reduce the work load of people.Can realize realizing selective erase to blackboard by ejecting device.Blackboard eraser transverse shifting adopts electric capstan, is convenient to this device to be arranged on large-scale blackboard and (avoids manufacturing the difficulty of long tooth bar or long lead screw).Easy manufacture, is convenient to transport, convenient storage.

Detailed description of the invention
As shown in Figure 1, the utility model automatic blackboard eraser, comprises blackboard eraser motion, blackboard eraser transverse moving mechanism, blackboard eraser lifting mechanism, control section; Described blackboard eraser motion is made up of crank rocker transmission mechanism; Described blackboard eraser transverse moving mechanism is made up of electric wire rope pulling mechanism; Described blackboard eraser lifting mechanism inhales drawing device as power by electromagnetism; Described control section controls mechanical part by the switch of each motor of No. four remote controller Long-distance Control.
Wherein, the feature of described blackboard eraser 2 motor pattern is, two blackboard erasers 2 do fan-shaped swing as vehicle wiper.Erasing area is larger.This device drives crank and rocker mechanism to realize fan-shaped oscillating motion by blackboard eraser by motor 11.What described blackboard eraser 2 transverse shifting adopted is by electric capstan 13 folding and unfolding steel wire rope 12, and pulls the movable floor 8 installing whole blackboard eraser motion to move by steel wire rope 12, thus realizes the transverse shifting of blackboard eraser 2.The movable floor 8 installing blackboard eraser motion is by two guide rail 10(14) be arranged on whole automatic blackboard eraser framework, electric capstan 13 is fixed thereon, and steel wire rope 12 is connected with movable floor 8 by two pulleys 5 being arranged on automatic blackboard eraser framework.The lifting mechanism running of described blackboard eraser is inhaled drawing device 16 by electromagnetism and is realized, its running produces magnetic after being energized by solenoid to be inhaled by iron core dynamic, by pull bar with rotate torque arm 6 and pull rotate to an angle installing the support baseboard rotating shaft 7 of blackboard eraser, thus realize blackboard eraser and lift (not wiping).Described control section controls remote controller by four tunnels and consists of Control 2 motor and an electromagnetism suction drawing device 16.
operation principle
When we need to erase the board time, user only need press the A switch on remote controller, driven by motor crank and rocker mechanism setting in motion, now starts to erase the board, when blackboard eraser needs walking time, press B switch, drive blackboard eraser moves, and blackboard eraser moves along blackboard, and erases the board, when blackboard erasing machine moves at the end, press C switch and just can carry out return motion.
Do not need whole erasing blackboard.Need optionally to wipe, at this time we only need the D switch pressed on remote controller, now electromagnetism inhales the motion of drawing device drive pull bar, and driven rotary torque arm and support baseboard rotating shaft turn an angle (about 10 degree), now blackboard eraser departs from blackboard, although blackboard eraser is still moving, can not writing on erasing blackboard.When we need to continue to erase the board time, only need again to press D switch, electromagnetism is inhaled drawing device and is resetted, and blackboard eraser just comes back to blackboard plane, continues erasing blackboard.
Embodiment recited above is only be described the preferred embodiment of the present invention, not limits the spirit and scope of the present invention.Under the prerequisite not departing from design concept of the present invention; the various modification that this area ordinary person makes technical scheme of the present invention and improvement; all should drop into protection scope of the present invention, the technology contents of request protection of the present invention, all records in detail in the claims.
