Description

The automatically controlled device that sweeps up dust of chalk dust ledge
Technical field
The utility model belongs to teaching aid technical field, specifically, and the particularly automatically controlled device that sweeps up dust of a kind of chalk dust ledge.
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 automatically controlled device that sweeps up dust of chalk dust ledge of simple operation.
The technical solution of the utility model is as follows: the automatically controlled device that sweeps up dust of a kind of chalk dust ledge, 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), 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 (8) 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, slipper push chalk end is towards the direction motion of 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, 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.The gauge tap of motor is arranged on the bottom surface of cell body, good concealment, and do not affect operation.
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, and the structural strength of slide block is good, not yielding or damage; On the other hand, it is convenient that cantilever is installed, and connects not only firmly but also reliable.
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 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, 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, the vertical front bulkhead that inserts slide block 6 of this cantilever 9, both threaded engagement.Described cantilever 9 stretches out forward the front cell wall of cell body 1, and the hole 8 of passing through for cantilever 9 on the front cell wall of cell body 1 is strip, and the left end in this hole 8 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, 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, and the gauge tap of motor 3 is arranged on the bottom surface of cell body 1.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 gauge tap 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 will drive the cantilever 9 direction motion of edge joint ash bucket 4 left, and slide block 6 is with cantilever 9 motions.In motion process, slide block 6 promotes chalk end towards the direction motion of left side ash bucket 4; Simultaneously, the most of chalk dusts that retain in groove are also promoted by slide block 6, remaining chalk dust is carried out wiping and is adsorbed clean by the sponge 7 of slide block 6 bottoms, when slide block 6 moves to ash bucket 4 top, the left side, chalk end and chalk dust are fallen in left side ash bucket 4 under the effect of gravity, by left side ash bucket 4, are collected.In the time of cleaning next time, the output shaft reversion of motor 3, makes the slide block 6 direction motion of edge joint ash bucket 4 to the right, and motion mode is same as described above, and therefore not to repeat here.
