Abstract

Disclosed is a lifting type dust-removing self-cleaning blackboard which realizes height adjustment of the board surface, automatic cleaning and prevention of dust flying. It consists of wooden boards, wooden troughs, slideways, eraser motors, screw motors, couplings, bearings, bearing housings, shafts, eraser brushes, blackboards, pulleys, lead screws, and nuts. The lead screw motor drives the lead screw to rotate through the coupling, and the lead screw rotates to drive the nut to move, realizing the function that the blackboard can move up and down. The eraser motor drives the shaft and the eraser brush to rotate through the coupling to realize the function of automatically wiping the blackboard. The wiper brush is lower than the plank height from the ground and the wiper brush is in the blackboard device to realize the function of preventing dust from flying.

Description

Lifting dust removal self-cleaning blackboard

Technical field

The utility model relates to a teaching device. Especially the self-cleaning self-cleaning blackboard with adjustable board height, automatic cleaning and dust prevention.

Background technique

At present, blackboards are mainly fixed on the walls of classrooms and need to be cleaned manually. The height of the blackboard from the ground cannot be adjusted and the deficiencies of dust flying exist.

Contents of the invention

In order to overcome the disadvantages of the non-adjustable height of the blackboard from the ground and the lack of dust flying, the utility model provides a self-cleaning blackboard with lifting dust removal. The lift-type dust-removing self-cleaning blackboard not only has an adjustable blackboard height and can be cleaned automatically, but also achieves the goal of preventing dust from flying.

The technical scheme that the utility model device solves its technical problem adopts is: by plank, wooden trough, slideway, eraser motor, lead screw motor, shaft coupling, bearing, bearing block, axle, eraser brush, blackboard, pulley, wire Composed of bars and nuts. The pulleys are fixed at the left and right ends of the blackboard, the pulleys are constrained in the slideway, the slideway is fixed on the wooden board, the wooden board fixes the bearing seat, the bearing seat and the bearing fit, the bearing fits with the shaft, the shaft fixes the wiper brush, the shaft is connected with the coupling, and the shaft is coupled The eraser is connected to the eraser motor, the eraser motor is fixed on the wooden groove, the wooden groove is fixed on the wooden board, the screw motor is fixed on the wooden groove, the screw motor is connected to the coupling, the coupling is connected to the lead screw, the lead screw and the nut cooperate, the nut pinned to the blackboard. When working, the lead screw motor drives the lead screw to rotate through the coupling, and the lead screw rotates to drive the nut to move, realizing the function that the blackboard can move up and down. The eraser motor drives the shaft and the eraser brush to rotate through the coupling to realize the function of automatically wiping the blackboard.

The beneficial effects of the utility model: the lead screw motor drives the lead screw to rotate through the shaft coupling, and the lead screw rotates to drive the nut to move, realizing the function that the blackboard can move up and down. The eraser motor drives the shaft and the eraser brush to rotate through the coupling to realize the function of automatically wiping the blackboard. The wiper brush is lower than the plank height from the ground and the wiper brush is in the blackboard device to realize the function of preventing dust from flying.
