The invention belongs to the technical field of mathematics teaching, and particularly relates to a drawing device for mathematics teaching. The drawing device comprises a bottom plate; the bottom ofthe bottom plate is fixedly connected with an idler wheel, and the top of the bottom plate is fixedly connected with a supporting rod; and the top of the supporting rod is fixedly connected with a waste box, and the surface of the waste box is movably connected with a movable cover through hinges. According to the drawing device, by arranging the idler wheel, the device can be moved conveniently;through the waste box, dust falling from chalk during drawing can be collected to prevent the situation that the dust falls to the bottom of a teaching frame and consequently cannot be cleared; through a rotating motor, the rotating motor works to drive a lead screw to rotate, the lead screw drives a threaded block and a connecting plate to move left and right, and thus a drawing on a writing board is erased automatically; through a dust collector, the dust generated during working of a board wiper can be sucked and is conveyed into a storing tank through a dust collection pump, and thus people are prevented from sucking the excessive dust; and the whole device is reasonable in structure, convenient to use and high in practicability.
本发明属于数学教学技术领域,尤其为一种数学教学用绘图装置,包括底板,所述底板的底部固定连接有滚轮,所述底板的顶部固定连接有支撑杆,所述支撑杆的顶部固定连接有废料箱,所述废料箱的表面通过合页活动连接有活动盖;本发明,通过设置滚轮,可方便装置进行移动,通过废料箱,可将在绘图时粉笔掉落的粉尘进行收集,避免粉尘掉落到教学框的底部而无法清理,通过转动电机,转动电机工作带动丝杆转动,丝杆转动带动螺纹块和连接板左右移动,从而自动将写字板上的图擦掉,通过吸尘器,可将板擦工作时产生的粉尘进行吸收,并通过吸尘泵输送到储料槽中,从而避免人们吸收过多的粉尘,整个装置结构合理,使用方便,实用性强。
