Description

The chalk dust ledge device that automatically sweeps up dust
Technical field
The utility model belongs to teaching aid technical field, specifically, and particularly a kind of chalk dust ledge device that automatically sweeps up 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, 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 above-mentioned cleaning slide block can only manual drives, inconvenient operation not only, labour intensity is larger, and 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 ledge of simple operation device that automatically sweeps up dust.
The technical solution of the utility model is as follows: a kind of chalk dust ledge device that automatically sweeps up dust, comprise notch cell body (1) upward, one end of described cell body (1) is sealed by baffle plate (8), the other end of cell body (1) is uncovered, and being provided with ash bucket (4) in the uncovered below of this end of cell body (1), 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); 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, and in motion process, slide block will promote the direction motion of chalk end towards ash bucket.The most of chalk dusts that retain in groove are also by slipper push, 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.
Described slide block (6) is rectangle hollow structure, and by injection mo(u)lding, cantilever (9) inserts the front bulkhead of slide block (6), both threaded engagement.Processing and fabricating is easy on the one hand, cost is low for above structure; On the other hand, the structural strength of slide block is good, not yielding or damage, and cantilever installation is convenient, and fastness is good.
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 8 as shown, and the left end of cell body 1 is uncovered, and cell body 1 left end uncovered below be provided with ash bucket 4, 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, and by injection mo(u)lding, the bottom of this slide block 6 is provided with sponge 7, and described sponge 7 is by being adhesively fixed on the bottom of slide block 2.
As shown in Figure 1 and Figure 2, in the front end cantilever mounted 9 of described slide block 6, this cantilever 9 inserts the front bulkhead of slide block 6, both threaded engagement.Described 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 8.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, slide block 6 promotes chalk end towards the direction motion of ash bucket 4; Simultaneously, the most of chalk dusts that retain in groove are also promoted by slide block 6, and remaining chalk dust is carried out wiping and adsorbed totally by the sponge 7 of slide block 6 bottoms, when 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, by ash bucket 4, are collected.
