Abstract

A mathematical formula demonstration training and identification integrated device disclosed by the present invention comprises a writing board, one end of the writing board is movably connected with an efficient erasing mechanism, an erasing push plate is pushed to slide along a horizontal chute, and a limiting roller and a limiting rotating rod are driven to rotate; the blackboard eraser is scientific and reasonable in structure and safe and convenient to use, an efficient erasing mechanism is arranged, an erasing push plate is pushed to slide along a horizontal sliding groove to drive a limiting rolling wheel and a limiting rotating rod to rotate, the blackboard eraser can be used for erasing chalk writing, and the blackboard eraser can be used for erasing the chalk writing. Through cooperation of a driving gear, a driven gear, a transmission rod, a transmission wheel and an elastic transmission belt, power is transmitted, the brush roller is driven to rotate reversely, chalk writing on the writing board is erased, meanwhile, dust on the brush roller is scraped off through a scraper, and the situation that the dust on the brush roller is excessively adhered is prevented.

Description

technical field [0001] The invention relates to the technical field of mathematics, in particular to an integrated device for demonstration, training and recognition of mathematical formulas. Background technique [0002] Mathematical formula is an expression method that people find when they study things in nature and express it in a certain way. It is an equal or unequal connection between the quantities of different things in nature. It accurately reflects the relationship between the interior and exterior of things, and is the basis for us to reach from one thing to another, so that we can better understand the essence and connotation of things; [0003] However, the existing mathematical formula demonstration device, when erasing handwriting, is accompanied by a large amount of dust and dust, which affects the surrounding environment, and long-term inhalation of dust and dust will also cause harm to people's bodies, so we are concerned about these situations. , in orde...
