Fixed bin is welded with before plate on front side of table wall, is connected along the vertical direction by the multiple beam barrels rotation being placed equidistant with inside the fixed bin
Multiple second gear disks are connected to, the multiple beam barrel rear end is welded through fixed bin and with brush plate, the multiple second gear
Disk is intermeshed between any two, and the second gear disk engagement of top is connected with first gear in multiple second gear disks
Disk, the first gear disk engage connection with the rack gear that level is welded on upper housing inner surface wall.
Wherein, the brush plate centre offers the through-hole of penetration type, and brush plate and table wall before clipboard are close
Fitting.
Wherein, the length of the fixed bin is equal with clipboard height size, and also fixation connects on table wall before fixed bin
It is connected to dust hood.
Wherein, described lead screw one end is passed by output shaft with the either-rotation motor being fixed on the lower case side appearance wall
Dynamic connection.
Wherein, the multiple beam barrel front end runs through fixed bin and extends to the dust hood inner cavity, and table before dust hood
It is communicated with air pump on wall, the air pump is connected to by pipeline with the dust-collecting box for being removably mounted at before dust hood on table wall.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are:
1, in the utility model, lead screw rotation is driven by either-rotation motor, so that nut set moves up in the horizontal direction
It is dynamic, mobile drive fixed bin is covered by nut and is moved horizontally, first gear disk rotates under the engagement of rack gear at this time,
It is rotated by first gear disk, drives multiple second gear disk common rotations, and adjacent in multiple second gear disks two
The rotation direction of second gear disk is on the contrary, so that two adjacent brush plates are equally reversely rotated, in the shifting of brush plate level
Rotation is carried out during dynamic, completes the efficient wiped clean of letter written with chalk, high degree of automation, laborsaving convenience.
2, it in the utility model, is worked by air pump so that brush plate centre generation air negative pressure, negative by air
Pressure acts on, and the chalk dust generated in wiping process is entered in dust hood by beam barrel, and eventually enters into dust-collecting box and collect, and leads to
The structure is crossed, the timely collection of chalk dust is realized, chalk dust splashing is avoided, improves the air environment in teaching region, protect
Teachers and students' respiratory health is demonstrate,proved.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only to explain this
Utility model is not used to limit the utility model.
Referring to Fig.1-3, a kind of literary education teaching aid, including clipboard 1, about 1 two sides of clipboard are respectively welded
Shell 10 and lower case 7,7 inner horizontal of lower case be equipped with lead screw 6, and be socketed on lead screw 6 nut set 5, nut set 5 top and
Fixed bin 3 is welded on front side of table wall before clipboard 1, passes through the multiple axis being placed equidistant with along the vertical direction inside fixed bin 3
Cylinder 15 is rotatably connected to multiple second gear disks 14, and multiple 5 rear ends of beam barrel are welded through fixed bin 3 and with brush plate 2, Duo Ge
Two toothed discs 14 are intermeshed between any two, and the second gear disk 14 of top engages connection in multiple second gear disks 14
There is first gear disk 8, first gear disk 8 engages connection with the rack gear 9 that level is welded on 10 inner surface wall of upper housing.
2 centre of brush plate offers the through-hole of penetration type, and brush plate 2 is fitted closely with table wall before clipboard 1, Gu
The length for determining box 3 is equal with 1 height size of clipboard, and is also fixedly connected with dust hood 13, lead screw before fixed bin 3 on table wall
6 one end are sequentially connected by output shaft with the either-rotation motor 4 being fixed on 7 side appearance wall of lower case, multiple 15 front ends of beam barrel
Run through fixed bin 3 and extend to 13 inner cavity of dust hood, and be communicated with air pump 12 before dust hood 13 on table wall, air pump 12 passes through pipe
Road is connected to the dust-collecting box 11 for being removably mounted at before dust hood 13 on table wall.
Brush plate 2 is fitted closely with table wall before clipboard 1, to guarantee that brush plate 2 can be by letter written with chalk wiped clean, axis
Cylinder 15 is the structure of inner hollow, on the one hand for fixing second gear disk 14, on the other hand, facilitates passing through for chalk dust,
2 centre of brush plate may make to generate air negative pressure by air pump 12, to facilitate extraction chalk dust.
Working principle: in use, driving lead screw 6 to rotate by either-rotation motor 4, so that nut set 5 is in the horizontal direction
