a teaching device

Abstract

The invention belongs to the technical field of teaching equipment, and particularly relates to a teaching equipment, which includes a blackboard and a base. The areas that can be scanned by the two scanning modules set in the present invention include all areas on the front side of the blackboard; the two scanning modules will The scanned information is converted into an electronic signal, and then transmitted to the switch control module, through which the servo motor is controlled to work, and then the rotation of the driving wheel is controlled; the rotation of the driving wheel drives the belt to move, and the belt moves to drive the belt placed on its upper side. The movement of the blackboard eraser makes the movement of the blackboard eraser always follow the user, which is convenient for the user to take. In the present invention, when the belt is driven by the driving wheel to move toward one side, the cover plate of the storage box on this side will be opened relative to the storage box under the transmission of the corresponding gear and rack, and the chalk brushed by the brush layer on the inner surface of the belt will be opened. The ash falls into the storage box on that side along the moving direction of the belt and is collected.

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
