Abstract
A kind ofly realize plate face height adjustable, automatically to clean and the lift dedusting automatically cleaning blackboard that prevents dirt from flying.It is made up of plank, trogue, slideway, blackboard eraser motor, leading screw motor, shaft coupling, bearing, bearing block, axle, wiping board brush, blackboard, pulley, leading screw, nut.Leading screw motor drives screw turns by shaft coupling, and screw turns drives nut to move, and realizes blackboard function moving up and down.Blackboard eraser motor is rotated by shaft coupling band moving axis and wiping board brush, realizes the function that blackboard is cleaned automatically.Wiping board brush distance ground level lower than plank height and wiping board brush in blackboard device, realize prevent dirt from flying function.
Description
Art
The utility model relates to a kind of instructional device.Especially realize plate face height adjustable, automatically to clean and the lift dedusting automatically cleaning blackboard that prevents dirt from flying.
Background technology
At present, blackboard is mainly fixed on the wall in classroom, and needs manually to clean.There is the deficiency that blackboard flies apart from the irreconcilable dirt of ground level.
Summary of the invention
In order to overcome the deficiency that blackboard flies apart from the irreconcilable dirt of ground level, the utility model provides a kind of lift dedusting automatically cleaning blackboard.This lift dedusting automatically cleaning blackboard not only blackboard height adjustable, automatically clean, and realize prevent dirt from flying target.
The utility model device solves the technical scheme that its technical problem adopts: be made up of plank, trogue, slideway, blackboard eraser motor, leading screw motor, shaft coupling, bearing, bearing block, axle, wiping board brush, blackboard, pulley, leading screw, nut.Two ends, blackboard left and right fixed block, pulley constrains in slideway, and slideway is fixed on plank, plank fixed bearing block, bearing block and bearing fit, bearing and axle coordinate, axle fixes wiping board brush, and axle is connected with shaft coupling, and shaft coupling is connected with blackboard eraser motor, blackboard eraser motor is fixed on trogue, and trogue is fixed on plank, and leading screw motor fixed by trogue, leading screw motor connects shaft coupling, shaft coupling connects leading screw, and leading screw and nut screw connection, nut is fixed on blackboard.Operationally, leading screw motor drives screw turns by shaft coupling, and screw turns drives nut to move, and realizes blackboard function moving up and down.Blackboard eraser motor is rotated by shaft coupling band moving axis and wiping board brush, realizes the function that blackboard is cleaned automatically.
The beneficial effects of the utility model: leading screw motor drives screw turns by shaft coupling, screw turns drives nut to move, and realizes blackboard function moving up and down.Blackboard eraser motor is rotated by shaft coupling band moving axis and wiping board brush, realizes the function that blackboard is cleaned automatically.Wiping board brush distance ground level lower than plank height and wiping board brush in blackboard device, realize prevent dirt from flying function.
