It does a cleaning brush and connects with the one-to-one adjusting part of cleaning brush, the upper end of installing plate and the sliding nut of upper driving device
It connects, the lower end of installing plate is connect with the sliding nut of lower driving device, several cleaning brush are closely arranged along installing plate length direction
Cloth, and cleaning brush is connect close to the side of installing plate by telescopic rod with installing plate；Adjusting part includes rotating handles and stretches
Axis, rotating handles are rotatablely connected by bearing and installing plate, and one end of rotating handles towards installing plate opens up fluted, groove side
Wall has an internal thread, and there is telescopic shaft outer wall external screw thread, one end of telescopic shaft to be stretched into groove after passing through installing plate and and groove
Internal thread engagement, the other end of telescopic shaft is fixedly connected with corresponding cleaning brush.
Compared with prior art, the present invention has the following advantages：
(1) two motor synchronous rotary can drive installing plate to move to the left or to the right, clear on installing plate so as to drive
Clean brush movement, cleaning brush clean blackboard during movement, realize automated cleaning, and cleaning efficiency is high；And it can pass through
Rotation rotating handles make cleaning brush close to blackboard or far from blackboard, so as to adjust clean region, using flexible；
(2) one dust collection mechanism is respectively set in the both sides of installing plate, during dust is sucked while automatic-cleaning backboard
In empty capsid, dust the drawbacks of falling under gravity into dust-collecting box, preventing dust from flying after wind turbine is closed, is greatly changed
Sanitation and hygiene inside and outside classroom, beneficial to the health of teachers and students；
(3) dust-collecting box is detachably connected with hollow housing, convenient for the dust in processing dust-collecting box.
Description of the drawings
Attached drawing described herein is used for providing further understanding of the present application, the part of the application is formed, at this
The same or similar part, the illustrative embodiments and their description of the application are represented using identical reference label in a little attached drawings
For explaining the application, the improper restriction to the application is not formed.In the accompanying drawings：
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the structure diagram of cleaning mechanism of the present invention.
Specific embodiment
Purpose, technical scheme and advantage to make the application are clearer, below in conjunction with drawings and the specific embodiments, to this
Application is described in further detail.For the sake of simplicity, it is omitted that well known to a person skilled in the art certain skills in being described below
Art feature.
As shown in Figure 1, the present embodiment provides a kind of automatic erasing blackboard machine, the upper driving including being located at 2 top edge of blackboard fills
Put 1, the lower driving device 3 positioned at 2 lower edge of blackboard, the cleaning mechanism that is connected between upper driving device 1 and lower driving device 3
4.Upper driving device 1 and lower driving device 3 include screw 11, motor 13 and sliding nut 12,11 one end of screw and motor 13
Output terminal connection, sliding nut 12 is set on screw 11 and engaged with screw 11.As shown in Fig. 2, cleaning mechanism 4 includes erecting
The installing plate 47 that directly sets, several cleaning brush 46 and with 46 one-to-one adjusting part of cleaning brush, the upper end of installing plate 47
It being connect with the sliding nut 12 of upper driving device 1, the lower end of installing plate 47 is connect with the sliding nut 12 of lower driving device 3, if
A dry cleaning brush 46 is closely arranged along 47 length direction of installing plate, ensures that there is no cleaning blind areas between two cleaning brush 46；Clearly
Clean brush 46 is connect close to the side of installing plate 47 by telescopic rod 45 with installing plate 47, and telescopic rod 45 can hang down with installing plate 47
