Abstract
The utility model discloses a kind of automatic eraser device, comprise blackboard and blackboard eraser, described blackboard eraser is drum type brake blackboard eraser, the upper and lower of described blackboard is provided with two screw rods that can freely rotate, the longitudinal direction of described blackboard eraser is arranged on blackboard, the two ends up and down of blackboard eraser are bolted on screw rod, are also provided with a drive motors, and the driving shaft of described drive motors is by toothed belt transmission connecting screw rod.The utility model drives the rotation of Timing Belt by motor work, thus drives bolt rotary, is driving the movement of blackboard eraser to realize work by bolt rotary.Prevent chalk dust from disorderly flying so added a dustproof shell on blackboard eraser.Therefore automatic blackboard eraser uses theory of mechanics and adds dust guard, in minimizing teachers and students physical demands, also greatly reduces the infringement of dust to teachers and students' health while improving classroom teaching efficiency.
Description
Technical field
The utility model relates to the field such as physics and mechanics, particularly a kind of automatic eraser device.
Background technology
In traditional teaching mode, blackboard, chalk and blackboard eraser are indispensable three large instruments in teaching, but traditional mode of erasing the board wastes time and energy, the health of what the dust danced in the air all over the sky was serious affect teachers and students.
Summary of the invention
In order to overcome above-mentioned defect, the utility model provides a kind of automatic eraser device that can solve the problem.
The utility model in order to the technical scheme solving its technical problem and adopt is: a kind of automatic eraser device, comprise blackboard and blackboard eraser, described blackboard eraser is drum type brake blackboard eraser, the upper and lower of described blackboard is provided with two screw rods that can freely rotate, the longitudinal direction of described blackboard eraser is arranged on blackboard, the two ends up and down of blackboard eraser are bolted on screw rod, are also provided with a drive motors, and the driving shaft of described drive motors is by toothed belt transmission connecting screw rod.
As further improvement of the utility model, the two ends of described screw rod are rotated by bearing and are fixed on carrier base.
As further improvement of the utility model, described blackboard eraser is also provided with dustproof shell.
As further improvement of the utility model, the two ends of described screw rod are provided with synchronous pulley, and the driving shaft of described drive motors is also provided with synchronous pulley, and described Timing Belt is set on synchronous pulley.
The beneficial effects of the utility model are: the utility model drives the rotation of Timing Belt by motor work, thus drive bolt rotary, are driving the movement of blackboard eraser to realize work by bolt rotary.Prevent chalk dust from disorderly flying so added a dustproof shell on blackboard eraser.Therefore automatic blackboard eraser uses theory of mechanics and adds dust guard, in minimizing teachers and students physical demands, also greatly reduces the infringement of dust to teachers and students' health while improving classroom teaching efficiency.
