Chalk dust recovery device

Abstract

The invention discloses a chalk dust recovery device and relates to the technical field of teaching equipment. A conveying device, a distribution device and a recovery device body are matched, whereinthe conveying device is installed below a blackboard, and chalk dust produced in writing directly falls into the conveying device; the distribution device is installed at the right end of the conveying device and can distribute abandoned chalk and chalk dust into the recovery device body automatically; and the recovery device body is installed on the lower portion of the distribution device. By means of the chalk dust recovery device, automatic clearing and collection of chalk dust are achieved, secondary air pollution caused by raising of chalk dust when a cleaning cloth is used for wiping and clearing is avoided, and the technical problems that in relevant technologies, chalk dust produced in the using process of the blackboard is difficult to clear and secondary air pollution in a classroom is caused are solved. The chalk dust recovery device is reasonable in design, simple in structure, easy to replace and clean and high in wiping efficiency, saves time, is not liable to cause raising dust and reduces harm.

Description

technical field [0001] The invention relates to the technical field of teaching equipment, in particular to a chalk dust recovery device. Background technique [0002] In the teaching process, the blackboard is one of the indispensable teaching tools for teachers. Chalk dust is extremely harmful to the health of teachers. At present, there are many dust-free chalks on the market, but the hazards of chalk dust still cannot be changed. , just reduced some. And there is not yet a kind of effective device that can really reduce dust emission so as to reduce the harm of dust to teachers' health. Through relevant research and research, a blackboard of a chalk dust recovery device is designed to overcome the limitations of the prior art. Contents of the invention [0003] According to the deficiencies in the prior art above, the technical problem to be solved by the present invention is to propose a chalk dust recovery device, which solves the automatic cleaning and collection ...
