Description
Technical field
The utility model belongs to teaching aid technical field, specifically, and particularly a kind of electric-controlled type chalk dust ledge cleaning structure.
Background technology
Blackboard plays a part very important in teaching practice, applies very extensive.At present, in order to solve the problem of the remaining chalk end of cleaning chalk dust and use, a chalk dust ledge consistent with blackboard length is set mostly under blackboard, in the time that people write on blackboard or after writing, chalk end and used up chalk dust directly fall in this groove, and then sweep with burnisher, though this setting has solved the problem of cleaning chalk end and chalk dust to a certain extent, but be difficult to thoroughly cleaning, and scale removal process is more loaded down with trivial details.
For this reason, there is people that a cleaning slide block is set in chalk dust ledge, clear up chalk end and chalk dust by the slip of cleaning slide block.But in the process of sliding at cleaning slide block, chalk end is easy to be stuck in the gap between slide block and cell wall, thereby having hindered slide block continues to push ahead, need to end cleaning work, the chalk end of jam is taken out and just can be proceeded, so on the one hand complex operation, inconvenience; On the other hand, the efficiency of cleaning is low, and the effect of cleaning is also undesirable.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of electric-controlled type chalk dust ledge cleaning structure of simple operation.
The technical solution of the utility model is as follows: a kind of electric-controlled type chalk dust ledge cleaning structure, comprise notch cell body (1) upward, one end of described cell body (1) is sealed by baffle plate (10), the other end of cell body (1) is uncovered, and be provided with ash bucket (4) in the uncovered below of this end of cell body (1), the outline of described ash bucket (4) is up big and down small tetragonous cone table, the one end at this ash bucket (4) top articulates mutually with cell body (1), and the other end at ash bucket (4) top is equipped with convertible handle, in described cell body (1), be provided with slide block (6), the bottom of this slide block (6) is fixed with sponge (7), and be provided with push pedal (8) at described slide block (6) towards one end of ash bucket (4), this push pedal (8) is arcuate structure, and arc top and the end of slide block (6) of push pedal (8) fix, in the front end cantilever mounted (9) of described slide block (6), this cantilever (9) stretches out forward the front cell wall of cell body (1), the hole (11) of passing through for cantilever (9) on the front cell wall of cell body (1) is strip, the front end of described cantilever (9) and screw mandrel (5) threaded engagement, described screw mandrel (5) parallels with cell body (1), support with cell body (1) mutually by bearing and bearing block (2) at the two ends of screw mandrel (5), and screw mandrel (5) the wherein end of one end is connected with the output shaft of motor (3), the gauge tap of described motor (3) is arranged on the bottom surface of cell body (1).
Adopt above technical scheme, when needs are cleared up chalk dust and chalk end, only need be by opening gauge tap, motor is started working, the output shaft of motor drives screw mandrel original place to rotate, the rotation of this screw mandrel is by the direction moving linearly that drives cantilever and slide block to ash bucket, in motion process, the push pedal of slide block one end is drawn chalk end together in, and promote the direction motion of chalk end towards ash bucket, gap between push pedal and cell body is less, can prevent that chalk end is stuck in the gap between slide block and cell wall, thereby guarantee the smoothness of scale removal process.The most of chalk dusts that retain in groove are also promoted by push pedal, remaining chalk dust carries out wiping by the sponge of slider bottom and absorption is clean, when slide block movement is to ash bucket when top, chalk end and chalk dust are fallen in ash bucket under the effect of gravity, are collected by ash bucket.As can be seen here, the utility model is not only time saving and energy saving, and uses very convenient, fastly, and the efficiency of cleaning is high, effective; The gauge tap of motor is arranged on the bottom surface of cell body, good concealment, and do not affect operation.Ash bucket is tetragonous cone table, and articulates mutually with cell body, and self structure is simple on the one hand, is easy to processing and fabricating, and production cost is low; On the other hand, ash bucket and cell body are easy to connect, and dismounting is very quick, are conducive to topple over fast chalk dust and the chalk end of collection; Meanwhile, convertible handle is installed on ash bucket, can convenient operation and mobile ash bucket.
Described slide block (6) is rectangle hollow structure, and slide block (6) and push pedal (8) are by injection mo(u)lding.Processing and fabricating is easy on the one hand, cost is low for above structure; On the other hand, slide block is good together with the structural strength of push pedal, not yielding or damage.Meanwhile, slide block is comparatively light and handy, operates more laborsaving.
Hurt sb.'s feelings in order to prevent that rotating part from exposing, described screw mandrel (5) and bearing block (2) are arranged in same guard shield, and this guard shield and cell body (1) fix.
For the ease of processing and fabricating, described sponge (7) is by being adhesively fixed on the bottom of slide block (2).
Beneficial effect: the utility model can be cleared up the chalk dust and the chalk end that drop in chalk dust ledge automatically, easily and quickly, has the features such as novel, simple in structure, easy to operate, transformation is easy, improvement cost is low.
