Abstract

The utility model discloses a curtain-type chalk dust erasing collector, comprising a blackboard eraser. A driving shaft is arranged on one side of a blackboard, driving wheels are respectively arranged on the upper part and the lower part of a driving shaft, a driven wheel is arranged on the other side of the blackboard in parallel to the driving wheel, the driving wheel and the driven wheel at the two ends of the blackboard are sleeved with annular transmission belts, a strip-shaped erasing device is vertically fixed between the two transmission belts, and a driving mechanism is arranged on the driving shaft to drive the driving shaft to rotate. The curtain-type chalk dust erasing collector disclosed by the utility model drives the erasing device by utilizing the driving wheel and the driven wheel so as to be capable of realizing a disposal quick erasing purpose and to save time and force. A large amount of instantly generated chalk dusts can be shielded and erased by utilizing curtain cloth, thus the chalk dusts fall down a bottom supporting embedding slot along the curtain cloth, the cleanness of a classroom is kept, and the physical and psychological health of teachers and students is improved. A purpose of automatic control can be realized by utilizing a spiral spring or a driving motor, thus the use is more convenient, and popularization and implementation are very favorable.

Description

Curtain formula chalk powder is wiped gathering-device
Technical field:
The utility model relates to cleaning blackboard apparatus, and particularly a kind of curtain formula chalk powder that does not have dust harzard is wiped gathering-device.
Background technology:
Chalk dust can fly upward everywhere when the blackboard eraser of extensive use now used, and it is unfavorable very greatly that teachers and students' health is had.For avoiding the harm of chalk, the method that people adopt now has: 1, use blank, the ink consumption of writing usefulness like this is very big, and some solvent when knowing is harmful; 2, make new dust-free blackboard or writing system, it is expensive that these have, and mostly need remove original blackboard, reinstalls new blackboard writing system, and it is huge to promote cost like this.So most of so far school uses is still old blackboard writing system, application number is that 91108697.8 patent of invention discloses a kind of full swing dust stratification railings eraser, can play similar effect, but complex structure, and volume is big, damages easily.
The utility model content:
The utility model proposes a kind of act of formula chalk powder and wipes gathering-device the problem and shortage that at present existing situation exists.
The technical scheme that the utility model adopted: a kind of act of formula chalk powder wiped gathering-device; Contain blackboard eraser, driving shaft is installed, the upper and lower driving wheel that is separately installed with of driving shaft in a side of blackboard; At the parallel driven pulley that is equipped with of blackboard opposite side with driving wheel; Be with the driving-belt of annular on the driving wheel at blackboard two ends and the driven pulley, be vertically fixed with the erasing apparatus of bar shaped between two conveyer belts, the driving mechanism that makes its rotation is installed on the said driving shaft.
Also be wound with flexible curtain on the driving shaft, an end in this curtain outside is connected on the erasing apparatus.
This driving mechanism is a clockwork spring, perhaps is motor.
Said erasing apparatus comprises a semi-enclosed support shell; This support shell and blackboard over against one side be provided with bar-shaped trough, be with a strip blackboard eraser in the bar-shaped trough, this blackboard eraser comprises gripper shoe and hairbrush; The width of gripper shoe is less than the width of bar-shaped trough inner chamber but greater than the width of bar shaped notch; Guarantee that it can at will not come off, hairbrush stretches out outside the bar-shaped trough, between bar-shaped trough bottom and blackboard eraser gripper shoe, is provided with top pressure spring simultaneously.
The upper and lower side of blackboard also comprises the embedded groove that is used for hiding conveyer belt and support erasing apparatus.
The upper end of erasing apparatus and/or lower end are provided with the horizontal pressure force support wheel that contacts with the embedded groove inwall.
The lower end of erasing apparatus is provided with the vertical pressure support wheel that contacts with embedded groove bottom or upper limb.
Be provided with the dedusting plate parallel at the edge of blackboard with erasing apparatus.
Both sides driving wheel and driven pulley inboard also are provided with transition wheel.
Driving wheel and driven pulley are sprocket wheel, and driving-belt is a chain; Perhaps driving wheel and driven pulley are gear, and driving-belt is the flexible belt that has tooth; Perhaps driving wheel and driven pulley are pulley, and driving-belt is a flexible rope.
The good effect of the utility model: utilize driving wheel and driven pulley to drive erasing apparatus, can play the purpose of disposable fast erasing, time saving and energy saving.Utilize curtain to block and wipe a large amount of chalk dusts that moment produces, chalk dust is dropped in the bottom support embedded groove along curtain, keep the classroom cleaning, improve teachers and students' physical and mental health.Utilize clockwork spring or drive motors can realize the automatically purpose of control, use conveniently, be beneficial to very much promotion and implementation.
