Description
Technical field
The utility model belongs to teaching aid technical field, specifically, and particularly a kind of chalk dust Automatic clearance 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, when 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, by the slip of cleaning slide block, clear up chalk end and chalk dust.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 chalk dust Automatic clearance structure of simple operation.
The technical solution of the utility model is as follows: a kind of chalk dust Automatic clearance 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, and 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 towards one end of ash bucket (4), be provided with push pedal (8) at described slide block (6), this push pedal (8) is arcuate structure, and arc top and the end of slide block (6) of push pedal (8) fix; Front end cantilever mounted (9) at 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 chalk end towards the direction motion of 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 is carried out wiping and is adsorbed clean by the sponge of slider bottom, 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, by ash bucket, are collected.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.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.
In order to prevent that rotating part from exposing, hurt sb.'s feelings, 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 automatically, cleaning easily and quickly drops into chalk dust and the chalk end in chalk dust ledge, have novel, simple in structure, easy to operate, transformation easily, the feature such as improvement cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of Fig. 1.
The specific embodiment
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 positioned at the below of blackboard, and extends along left and right directions, the notch of this cell body 1 upward so that accept chalk dust and chalk end.The right-hand member of described cell body 1 is sealed by baffle plate 10 as shown, the left end of cell body 1 is uncovered, and cell body 1 left end uncovered below be provided with ash bucket 4, the outline of described ash bucket 4 is up big and down small tetragonous cone table, the one end at these ash bucket 4 tops articulates mutually with cell body 1, and the other end at ash bucket 4 tops is equipped with convertible handle.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 towards one end of ash bucket 4, be provided with push pedal 8 at described slide block 6, 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, the gap between the cell wall corresponding with cell body 1 of the two ends of described push pedal 8 with 2-5mm, has the gap of 1-3mm between the bottom of push pedal 8 and the interior diapire of cell body 1.
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.
