Description
Technical field
The utility model relates to a kind of teaching appliance, and specifically a kind of blackboard connects ash-pit.
Background technology
At present, chalk remains the main tool of school instruction.Use chalk write or blackboard wiping in, chalk dust can be fallen the below of blackboard, so we see the blackboard lower end thick chalk dust of one deck that fallen through regular meeting.Because chalk dust is difficult for cleaning, can be bonded on clothes or the skin.In the cleaning chalk dust, the situation that chalk dust splashes can appear, both polluted environment, influenced healthy again.
Summary of the invention
The technical assignment of the utility model is the deficiency to prior art, provides a kind of blackboard reasonable in design, simple in structure to connect ash-pit.
The utility model solves the technical scheme that its technical problem adopted: comprise bracing frame; The bracing frame two ends are respectively arranged with runner, are connected through conveyer belt between the runner, and the bracing frame between the said runner is provided with support wheel and matches with conveyer belt; Be respectively arranged with rocking bar on the said runner; The runner below is respectively arranged with box body and hinged with its upper end, is provided with retaining cloth between runner and the box body, and retaining cloth is attached on the conveyer belt.
Support wheel is provided with 1～10.
Keep off the cloth two ends and be connected with bracing frame.
Support wheel is identical with the runner size.
The chalk dust that occurs in the use can be fallen on the conveyer belt; When chalk dust more for a long time; Can shake rocking bar at any end, make conveyer belt, chalk dust falls under gravity in the box body of runner below then; If the chalk dust that is bonded on the conveyer belt is arranged, can and drop in box body its removing attached to the retaining cloth on the conveyer belt.
A kind of blackboard of the utility model connects ash-pit compared with prior art, and the beneficial effect that is produced is:
Reasonable in design, simple in structure, easy to use, the phenomenon that dust splashes appears in the time of can preventing to remove chalk dust, prevent that teaching environment from being polluted, both brought convenience to teaching, avoided again exerting an influence to healthy.
