Description
Technical field
The utility model belongs to teaching aid equipment device field, particularly relates to a kind of novel blackboard eraser device.
Background technology
Often can by blackboard to student's impart knowledge during teachers' instruction, chalk write on blackboard after writing need to wipe with blackboard eraser, erase process must be completed by hand by teacher, when erasing the board, chalk dust unavoidably flies upward everywhere, not only affect environment, the more important thing is and can affect the healthy of teacher; In addition teacher needs to use arm writing on the blackboard on blackboard, needs equally to use arm, add the labour intensity of teacher when erasing the board.Therefore, be necessary to develop a kind of special equipment facilitating erasing blackboard.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and a kind of novel blackboard eraser device is provided, this device is arranged on the both sides at dais, the wiping operation of blackboard can be carried out by foot-operated mode, thus effectively alleviate the operation intensity of teacher, avoid flying upward of chalk dust when erasing the board simultaneously everywhere, ensure that teacher's is healthy.
In order to realize above-mentioned technical characteristic, the technical scheme that the utility model adopts is: a kind of novel blackboard eraser device, it comprises blackboard and blackboard eraser, it also comprises uploads moving axis and lower drive shaft, the two ends of two power transmission shafts are separately installed with fixed pulley, fixed pulley is connected with rope, rope is installed with cover plate, cover plate is installed with blackboard eraser, the both sides of blackboard are installed with chute, chute cover plate is connected with chute by bolt, lower turning cylinder is provided with driven pulley, driven pulley is meshed with driving chain, with driving wheel engaged transmission while of driving chain, driving wheel is provided with pedal.
The two ends of described cover plate are provided with limited block, and limited block matches with chute, realize cover plate left and right directions spacing.
Between described cover plate and blackboard eraser, spring is installed.
Described pedal is fixedly connected with driving wheel by bent axle, and pedal can positive and negative rotation drive driving wheel to rotate together.
Described driving chain is by the transmission that is meshed with driving wheel and driven pulley while of Chain conveyer.
The utility model has following beneficial effect:
First moving axis and lower drive shaft will be uploaded be fixedly mounted on the top up and down of blackboard, then chute is fixedly mounted on the left and right sides of blackboard, by blackboard eraser fixed installation on the cover board, cover plate and rope are fixedly linked simultaneously, by chute cover plate, cover plate is installed in chute again, in use, artificial foot pedals, driving wheel is driven to drive driven pulley by driving chain by pedal, and then drive rope to rotate around fixed pulley, moved up and down by the blackboard eraser on rope and wiping is carried out to blackboard, the labour intensity of manual working can be alleviated by foot-operated mode, the health problem that cover plate simultaneously by arranging can prevent chalk dust from flying upward everywhere and cause.
