一种用于黑板擦粉笔灰的环保清理装置
摘要：
本发明公开了一种用于黑板擦粉笔灰的环保清理装置，处理箱的一侧设有开合门，处理箱的内部设有两个固定块，两个固定块的下方固定有黑板擦，处理箱的另一侧设有滑轨，滑轨上设有滑块，滑块上连接有伸缩杆，伸缩杆连接有液压缸，滑块的一侧连接有连接杆，连接杆连接有塑料薄板，处理箱的顶部设有控制面板，处理箱的底部设有集尘箱，集尘箱的顶部设有网层，集尘箱与处理箱之间通过活动卡扣连接，该种装置，通过控制面板控制液压缸，驱动伸缩杆的不断拉伸和收缩，从而带动塑料薄板在黑板擦上不断击打，来除掉黑板擦上的粉笔灰，掉落的粉笔灰会经过网层落入集尘箱内，避免了粉笔灰弥漫在教室空气中，对人体造成伤害。
摘要（英）：

The invention discloses an environment-friendly removal device for chalk dust of an eraser. An openable door is formed in one side of a processing tank. Two fixing blocks are arranged inside the processing tank. The eraser is fixed below the two fixing blocks. The other side of the processing tank is provided with slide rails, and a slide block is arranged on the slide rails. The slide block is connected with a telescopic rod, and the telescopic rod is connected with a hydraulic cylinder. A connecting rod is connected to one side of the slide block and connected with a plastic sheet. A control panel is arranged on the top of the processing tank. A dust collecting tank is arranged at the bottom of the processing tank. A mesh layer is arranged on the top of the dust collecting tank. The dust collecting tank and the processing tank are connected through movable buckles. According to the environment-friendly removal device for chalk dust of the eraser, the hydraulic cylinder is controlled by the control panel to drive the telescopic rod to keep stretching and retracting, the plastic sheet is driven to continuously impact the eraser accordingly so that chalk dust on the eraser can be removed, the falling chalk dust falls into the dust collecting tank via the mesh layer, thus the chalk dust is prevented from being diffused in air in a classroom, and harm to human beings is avoided.
