Abstract
The utility model provides a motor -driven blackboard eraser. It includes motor, drive mechanism, electric control device, dust extraction, round brush, round brush synchronizer, movement bracket, guide rail, drive mechanism is that the motor passes through drive gear with the round brush of power transmission for reverse rotation, parallel translation about synchronous caterpillar track of a tractor messenger blackboard eraser, the electric control switch removes about making the blackboard eraser, can make the blackboard eraser stop in the blackboard optional position motion scope of the steerable blackboard eraser of travel switch. The beneficial effects of the utility model are that through making round brush reverse rotation, increase the area of contact of round brush and blackboard, reach better effect, the dust catcher can reduce dust pollution, and the dust catcher is established at outdoor degradable low noise, and easy operation, can realize remote control.
Description
Art
This utility model belongs to driven blackboard sassafras
Background technology
Presently used blackboard eraser is made up of with spongy body shell, simple in construction, operation inconvenience, inefficient, and the dust polluting environment produced.
Summary of the invention
Inefficient in order to solve existing blackboard eraser, pollute the deficiency of environment, this utility model provides a kind of electric blackboard eraser, is possible not only to Electronic control, and eliminates dust pollution.
This utility model solves its technical problem and be the technical scheme is that
It is made up of motor, drive mechanism, electric controller, dust exhaust apparatus, round brush, round brush synchronizer, motion bracket, guide rail.
The motor-driven gear that drive mechanism is integrally fixed on motor shaft engages with the travelling gear being provided with synchronous sprocket wheel rotary shaft, travelling gear and the direction of motion reversely rotate the travelling gear of round brush and engage, and reach to move in parallel about the blackboard eraser that round brush and the direction of motion reversely rotate.
Electric controller is that left-right switch controls motor positive and inverse, makes blackboard eraser move left and right, and shutdown switch can make blackboard eraser be parked in blackboard optional position, and the travel switch that blackboard both sides are fixed can control the range of movement of blackboard eraser.
Dust exhaust apparatus be the vacuum cleaner being located at outdoor by sweep-up pipe be together scheduled on traversing carriage the dust shield covering on blackboard by round brush and be tightly connected.
The power transmission shaft that round brush synchronizer is integrally fixed on travelling gear is installed with two synchronous sprocket wheel and the synchronization chain rail engagement being fixed on blackboard up and down.
The fixed hairbrush of cylinder spiral that round brush is integrally fixed on drum gear, sponge.
Motor, power transmission shaft, drum shaft are arranged on motion bracket, and motion bracket is equipped with directive wheel
Guide rail is the girder steel support being provided with chain rail, makes the most steadily to move in order to install motion bracket.
Said mechanism controls the synchronous sprocket wheel on driven by motor travelling gear, the round brush side-to-side movement of reverse rotation by electric controller, reaches the purpose cleaned off a blackboard；Vacuum cleaner passes through sweep-up pipe with dust shield by outside chalk dust discharge chamber.
This utility model provides the benefit that: owing to using above-mentioned design, it can increase the contact area of round brush and blackboard, reaches more preferable effect；Vacuum cleaner can reduce dust pollution, and vacuum cleaner is located at outdoor can reduce noise；And simple to operate, remote manipulation can be realized.
