Abstract

The invention provides a chalk processing box suitable for being mounted on a platform, and relates to the technical field of teaching equipment.The chalk processing box comprises a chalk storage bin, a chalk processing bin, a blackboard eraser cleaning bin, a dust collecting bin, an anti-sliding rubber mat, a partition plate and the like, wherein the chalk processing bin and the blackboard eraser cleaning bin are separated through the partition plate; according to the chalk processing box, it can be preferentially considered that the chalk box is installed on a platform in a classroom, chalk can be contained in the whole box in the chalk storage bin, ordered extrusion of single chalk can be achieved through the elastic cloth driven by a push-pull plate and an inclined storage bin bottom plate, a new face can be cut out for the single chalk through the cutter in the chalk treatment bin, the friction force between the chalk and a blackboard is increased, the chalk dust on a blackboard eraser can be cleaned by sliding the push-pull plate back and forth in the blackboard eraser cleaning bin, and the falling chalk dust and broken chalk ends can be cleaned in a concentrated mode through the chalk dust cleaning bin. Certain benefits are brought to chalk resources, environmental sanitation of a classroom and body health of teachers and students.

Description

technical field

[0001] The invention relates to the technical field of teaching equipment, in particular to a chalk processing box suitable for installation on a podium. Background technique

[0002] In the vast majority of school classrooms, the traditional blackboard writing activity is retained in teaching, and this activity will remain unchanged for a long time, especially when many teachers are habitually folded by hand when writing on the blackboard. A new piece of chalk is used to better write on the blackboard with the newly folded section of the chalk, but every time a new piece of chalk is thrown away.

[0003] This will lead to several problems, the most important of which are the waste of chalk resources, the sanitation of classrooms, and the health of teachers and students. At present, many inventions focus on the production design of a single holder for chalk, or on the invention design of a single solution to clean the chalk dust on the blackboard eraser. The...
