Teaching device

Abstract

The invention belongs to the technical field of teaching devices, and particularly relates to a teaching device. The teaching device comprises a blackboard and a base, an areas capable of being scanned by two scanning modules mounted in the device comprises all areas on the front side of the blackboard, the two scanning modules convert information obtained through scanning to electronic signals, then, the signals are transmitted to a switch control module, through the switch control module, a servo motor is controlled to work, a driving wheel is controlled to rotate, the driving wheel rotatesto drive a belt to move, the belt moves to drive a blackboard eraser placed on the upper side on the belt to move, moving of the blackboard eraser always follows a user, and taking by the user is facilitated. When the belt is driven by the driving wheel to move towards one side, a containing box cover plate on the side is transmitted by a corresponding gear and a corresponding rack to be opened relative to a containing box, chalk dust brushed by a brush layer on the inner face of the belt falls in the containing box on the side along with the moving direction of the belt, and collection is achieved.

Description

technical field [0001] The invention belongs to the technical field of teaching equipment, and in particular relates to a teaching equipment. Background technique [0002] The blackboard is a plane that can be repeatedly written with chalk. The board is hard and is mostly used for teaching. Blackboards are generally made of wood or frosted glass, and can be written on with specific writing materials such as chalk. [0003] During class, the words written on the blackboard need to be erased many times. At this time, a blackboard eraser is needed. The blackboard eraser is generally placed on the base of the lower side of the blackboard; but many times, when the blackboard needs to be wiped, the blackboard eraser and People are not in the same position. At this time, the user needs to go to the place where the blackboard eraser is placed and pick up the blackboard eraser to use, which inadvertently increases the unnecessary walking of the user; especially for teachers, it is e...

Problems solved by technology

[0003] During class, the words written on the blackboard need to be erased many times. At this time, a blackboard eraser is needed. The blackboard eraser is generally placed on the base of the lower side of the blackboard; but many times, when the blackboard needs to be wiped, the blackboard eraser and People are not in the same position. At this time, the user needs to go to the place where the blackboard eraser is placed and pick up the blackboard eraser to use, which inadvertently increases the unnecessary walking of the user; especially for teachers, it is easy to find the blackboard during the lecture. Rubbing interrupts the train of thought and affects the efficiency of lectures

[0004] Designing a device that drives the blackboard eraser to move with the user through a belt can solve the above problems, but when wiping the blackboard, it is easy to generate chalk dust; During the process, the chalk dust will be blown or vibrated again, affecting the surrounding environment and cleaning effect
