Description
Technical field
This invention relates to the cleaning plant technical field of blackboard eraser, specifically a kind of foot-operated blackboard eraser cleaning plant.
Background technology
Although the teaching means (such as multimedia teaching) of some advanced persons uses in teaching now; but most schools still with traditional blackboard and chalk for main teaching method; even if employed the school of advanced teaching means, there is a lot of course still from not blackboard and chalk.And present blackboard eraser use several lower after, be just stained with chalk powder, then continued to use the effect erased the board just to become very poor, affected teaching efficiency.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of foot-operated blackboard eraser cleaning plant can clearing up blackboard eraser dust in classroom fast.
The present invention realizes with following technical scheme: a kind of foot-operated blackboard eraser cleaning plant, comprises frame; Described frame is provided with the small band wheel shaft be parallel to each other, large belt shaft and pedal shaft; Described small band wheel shaft is fixed with small pulley and triangular cam; Described large belt shaft is provided with large belt wheel; Described large belt wheel is connected with small pulley by driving-belt; Described pedal shaft one end is fixed with pedal, is fixed with two linkages in the middle part of pedal shaft; Two described linkages comprise the straight-bar that two tops are hinged, and two linkage one end are fixed on pedal shaft, and the other end is hinged on large belt wheel end face;
Described frame be also provided with the clamping device of blackboard eraser and pat bar; Be hinged in frame in the middle part of described beating bar, pat bar one near triangular cam, the other end is near blackboard eraser surface; Described beating bar is fixed with and makes the automatically reset back-moving spring of beating bar on blackboard eraser one end; Back-moving spring one end is fixed in frame.
It is further: described clamping device is two to the arched elastic sheet metal be fixed in frame.
During use, blackboard eraser is needed to be arranged on clamping device, clamping device top arched elastic sheet metal makes, when filling blackboard eraser, pressing arched elastic sheet metal, making it to form decurved arch and clamp blackboard eraser, when blackboard eraser will be taken off, pull on arched elastic sheet metal, form upwards curved arch, just can take out blackboard eraser.The present invention adopts and tramps with one's feet as power source, when foot-treadle, pedal can produce reciprocally swinging, recycle two linkages swinging the rotation converting large belt wheel to, again by the accelerating function of V belt translation, rotation is delivered to is equipped with on the small band wheel shaft of triangular cam, utilize the continuous switching on the summit of triangular cam and limit, beating bar is driven constantly to swing around fulcrum, the afterbody patting bar contacts with triangular cam, head is used for beaing blackboard eraser, for ensureing to pat the afterbody of bar and the close contact of triangular cam, at the head patting bar, a back-moving spring is housed.
The invention has the beneficial effects as follows: volume is little, location is convenient, steps on as power source, can clear up the dust of blackboard eraser quick, simple and direct, easily with pin, improves teaching efficiency.
