Abstract
The invention relates to a magnetic electric blackboard eraser to solve the problems that a blackboard needs to be erased manually in class, and chalk dust caused by erasing leads to dust pollution and can not be recycled. The magnetic electric blackboard eraser is composed of a rack system, a transmission system, a control and power system, a chalk dust collecting system and the like and takes electric power as a driving energy source. The whole mechanism is supported and positioned by the rack system, the transmission system provides power and force for an erasing device so that the erasing device can be attached to the blackboard, the control and power system provides the power for driving the mechanism and controls the moving direction and the moving speed of the erasing mechanism, and the chalk dust collecting system collects chalk dust. The magnetic electric blackboard eraser has the advantages of being simple in structure and principle, ingenious in design, high in practicability and integrality, easy to machine, low in manufacturing price and convenient to popularize and provides the development direction for automatic healthy environment-friendly classrooms in the future.
Description
Technical field:
The present invention relates to realia technical field, relate in particular to a kind of can auto-erasing with collect the automation Non-dust blackboard device of blackboard chalk dust.
Background technology:
Chalk, blackboard teaching aid are the indispensable instruments of teaching at present, it is one of the most original and the most traditional main teaching method, it is applied to the history of existing several thousand now, indelible contribution has been made to the educational undertaking of the mankind, along with the progress of history and the development of society, the understanding of the mankind to chalk, blackboard teaching aid improves constantly, and namely chalk brings progress to mankind's educational undertaking and while making tremendous contribution, also brings huge harm to the teacher and student that are engaged in educational undertaking.
Along with socioeconomic development, the requirement of people to work, academic environment, healthy requirement and environmental protection, resource circulation utilization improves constantly.Attending class, to need to erase the board with the dust pollution caused that erases the board frequently be the problem perplexing teachers and students always, erase the board frequently and not only affect the efficiency of process that teacher attends class, Students ' Learning, and the chalk dust flown upward all over the sky can be made dirty the clothing of academics and students, the health of teacher is also endangered, and teaching environment is heavily polluted.According to national part data from investigation display, along with the quickening of social progress and social rhythm, the sick rate of teaching profession is in the trend risen year by year, occupational disease presents diversified future development, and wherein the pneumoconiosis that causes of dust and various acute and chronic breathing problem are China's main one in occupational disease at present.
Therefore, the hope that people are urgent can have a kind of blackboard not only can erasing chalk ash automatically, and chalk ash collection can be got up; dust can be prevented the pollution in classroom on the one hand; chalk dust can be made to recycle on the other hand, economize on resources, protection of the environment.Given this, the design of our team research and develop and is produced a kind of economical and practical and efficient automation dust-free blackboard.Blackboard is made up of Ban Bi mechanism, auto-erasing mechanism, chalk ash collection mechanism, Based Intelligent Control mechanism.Single-chip microcomputer is by controlling the rotation erasing chalk ash of driven by motor brush roll, and make chalk dust fall into the inside of blackboard eraser by the space in bristle holder plate, dust can fall in dust storage chamber under gravity automatically, greatly reducing waving of dust.When dust runs up to a certain amount of, open the dust outlet valve of bottom, can chalk dust be reclaimed, carry out the recycling of chalk dust, reduce production cost.Structural principle of the present invention is simple, deft design, and have practical, that globality is high, processing is simple, low cost and being convenient to is promoted feature, applicable mass market popularization is the developing direction in following automation health environment-friendly classroom.
Summary of the invention:
The present invention relates to a kind of can auto-erasing collect the automation Non-dust blackboard device of blackboard chalk dust, with solve attend class need manually to erase the board, blackboard wiping time produce the problem that chalk dust and chalk dust recycle.This device is made up of machine frame system, transmission system, control and the system such as dynamical system, chalk ash collection system.This device is frame material with lucite, take electric power as drive energy; Machine frame system provides support and the location of whole mechanism, transmission system provides power and provides erasing apparatus to be attached to power on blackboard, control and dynamical system provide the power of driving mechanism and control moving direction and the speed of erasing mechanism, chalk ash collection systematic collection chalk dust.Structural principle of the present invention is simple, deft design, have practical, globality is high, processing is simple, low cost and be convenient to the feature of popularization, is the developing direction in following automation health environment-friendly classroom.
The erasing of automation dust-free blackboard with collect gray device of chalk outsourcing housing (1) and outer baffle (2) by erasing and collect gray device of chalk and close, direct current generator (5) is connected with plum coupling (6), driving shaft (12), and permanent magnet driving wheel (23) is fixed on driving shaft (12); Hairbrush (9) and driving shaft (12) parallel installation, be fixed between motor mounting plate (3) and baffle plate (15) by two rhombus bearing blocks (10), motor mounting plate (3), baffle plate (15), base plate (16) are fixedly connected with by lucite glue with outsourcing housing (1); Permanent magnet support (14) is fixedly connected with by lucite glue with outsourcing housing (1), and permanent magnet (24) is connected on permanent magnet support (14); Little wheel support (19) connects steamboat (20); Travel switch (22) is fixed on two ends, outsourcing housing (1) left and right, top; The tank (17) that gathers dust is connected with base plate (16).
The erasing of automation dust-free blackboard and collection gray device of chalk are based on blackboard magnetic-adsorption.Device is made to be adsorbed on blackboard by permanent magnet driving wheel (23) and permanent magnet (24) by magnetic force, driven by power direct current generator (5), direct current generator (5) drives permanent magnet driving wheel (23) to rotate by driving shaft (12), and then makes whole device rectilinear motion; Permanent magnet (24) and steamboat (20) generator are attached to suction on blackboard and holding power; The startup of permanent magnet (24) travel switch (22) control device and stopping; Direct current generator (5) drives hairbrush (9) to rotate erasing chalk ash; the percent of automatization chalk dust improving classroom falls into the tank that gathers dust (17) by gravity; prevent chalk dust from causing dust pollution to classroom; the tank (17) that gathers dust can be backed out; chalk dust is recycled; economize on resources, protection of the environment.
