Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of blackboard for education that can certainly collect chalk dust, including a blackboard body, it is characterized in that: the bottom of described blackboard body is provided with a uncovered storage ash-pit, blackboard body lower surface is close to by described storage ash-pit, described storage ash-pit is internally provided with one and is fixed on the scraping block stored up bottom ash-pit, the lateral wall of described storage ash-pit is provided with a bar hole, a push rod it is provided with in described bar hole, described push rod is positioned at storage ash-pit one end and is connected in scraping block, one end that described push rod is positioned at outside storage ash-pit is connected to leader, it is provided with ash hole bottom described storage ash-pit two ends.
Described scraping block is set to cross section is taper, it is to avoid chalk dust is attached in scraping block, convenient.
The bottom of described scraping block is provided with a smooth slide plate, and the both sides of described slide plate are set to spill, facilitates and is thoroughly scraped by the ashes within storage ash-pit.
Described scraping block is provided with rubber slab with the side that connects, storage ash-pit two side, it is to avoid cause abrasion to inside storage ash-pit.
Described storage ash-pit is positioned at bottom ash hole and is provided with track plates, described track plates is provided with one can push-and-pull dismounting ash collection slot, facilitate after chalk ash collection, focus on.
This utility model is in use: when after chalk is write on blackboard, chalk dust is concentrated and dropped in storage ash-pit, scraping block within ash-pit is stored up to both sides push-and-pull either directly through handle push-and-pull, easily the chalk dust in storage ash-pit can be scraped the ash hole to storage ash-pit both sides, spill,.
The beneficial effects of the utility model are: this utility model is novel in design, simple in construction, by using the push-and-pull of scraping block, the i.e. mechanically removing realizing chalk dust, solving and remove that the workload that causes is big and hygienic issues manually, effect is notable, more convenient.
