Description

The device of Automatic clearance chalk dust
Technical field
The utility model belongs to teaching aid technical field, specifically, and particularly a kind of device of Automatic clearance chalk dust.
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 the device of the Automatic clearance chalk dust that a kind of simple operation is provided.
The technical solution of the utility model is as follows: a kind of device of Automatic clearance chalk dust, comprise notch cell body (1) upward, described cell body (1) is direct through groove structure, and is equipped with ash bucket (4) in the below of cell body (1) open at both ends, and this ash bucket (4) articulates mutually with cell body (1); 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, arc top and the end of slide block (6) of push pedal (8) fix, between cell wall corresponding to the two ends of described push pedal (8) and cell body (1), there is the gap of 2-5mm, between the bottom of push pedal (8) and the interior diapire of cell body (1), there is the gap of 1-3mm; 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) is wherein connected with the output shaft of motor (3) end of one end.
Adopt above technical scheme, when needs are cleared up chalk dust and chalk end, only needing to press breakdown closes, 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.
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.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1 and Figure 2, the cell body 1 of chalk dust ledge is the direct through groove structure that left and right directions extends, and is positioned at the below of blackboard, the notch of this cell body 1 upward so that accept chalk dust and chalk end.The below of the left and right open at both ends of described cell body 1 is provided with ash bucket 4, and this ash bucket 4 articulates mutually with cell body 1.In described cell body 1, be provided with slide block 6, described slide block 6 is rectangle hollow structure, the bottom of this slide block 6 is provided with sponge 7, described sponge 7 is by being adhesively fixed on the bottom of slide block 2, and be provided with push pedal 8 at described slide block 6 towards one end of ash bucket 4, slide block 6 and push pedal 8 are by injection mo(u)lding, this push pedal 8 is arcuate structure, arc top and the end of slide block 6 of push pedal 8 fix, between cell wall corresponding to the two ends of described push pedal 8 and cell body 1, there is the gap of 2-5mm, between the bottom of push pedal 8 and the interior diapire of cell body 1, there is the gap of 1-3mm.
As shown in Figure 1 and Figure 2, 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, and the hole 11 of passing through for cantilever 9 on the front cell wall of cell body 1 is strip, and the left end in this hole 11 is near ash bucket 4, and right-hand member is near baffle plate 10.The front end of described cantilever 9 and screw mandrel 5 threaded engagement, screw mandrel 5 parallels with cell body 1, and support with cell body 1 mutually by bearing and bearing block 2 at the two ends of this screw mandrel 5, and screw mandrel 5 is wherein connected with the output shaft of motor 3 end of one end.Described screw mandrel 5 and bearing block 2 are arranged in same guard shield, and this guard shield and cell body 1 fix.
Operation principle of the present utility model is as follows:
When needs are cleared up chalk dust and chalk end, the start button of opening motor 3, starts working motor 3, and the output shaft of motor 3 drives screw mandrel 5 original places to rotate, the rotation of screw mandrel 5 is by the direction motion that drives cantilever 9 to ash bucket 4, and slide block 6 is with cantilever 9 motions.In motion process, push pedal 8 is drawn chalk end together in, and promotes the direction motion of chalk end towards ash bucket 4; Simultaneously, the most of chalk dusts that retain in groove are also promoted by push pedal 8, and remaining chalk dust carries out wiping by the sponge 7 of slide block 6 bottoms and absorption is clean, in the time that slide block 6 moves to ash bucket 4 top, chalk end and chalk dust are fallen in ash bucket 4 under the effect of gravity, are collected by ash bucket 4.After having cleared up, motor 3 reverses, and makes slide block 6 get back to initial position, to wait for prune job next time.
