Further improvement as automatic blackboard cleaning device of the present utility model: the left end at lower guideway is provided with left lateral journey switch, is provided with right lateral journey switch at the right-hand member of lower guideway; Left lateral journey switch, right lateral journey switch link to each other with controller signals respectively with drive motors.

Further improvement as automatic blackboard cleaning device of the present utility model: below lower guideway, be provided with the powder ash-pit.

Further improvement as automatic blackboard cleaning device of the present utility model: be provided with screw in the slide block, internal thread on the screw and the external screw thread on the screw rod match.

Further improvement as automatic blackboard cleaning device of the present utility model: stripe board brushes and is provided with fur.

Automatic blackboard cleaning device of the present utility model can carry out wiping to blackboard automatically, has not only improved the utilization rate of time in classroom, has also reduced the chalk dust injury healthy to teachers and students.

Description of drawings

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.

Fig. 1 is the structural representation of automatic blackboard cleaning device of the present utility model;

Fig. 2 is the actual user mode schematic diagram of Fig. 1.

The specific embodiment

Embodiment 1, Fig. 1 have provided a kind of automatic blackboard cleaning device, comprise the drive motors 2 that is installed on the motor mount 3, be installed in the screw rod 6 on the screw rod mount pad 5 and be installed in lower guideway 10 on the guide rail mount pad 11; The left end of shaft coupling 4 links to each other with the motor shaft of drive motors 2, and the right-hand member of shaft coupling 4 links to each other with screw rod 6.

Suit slide block 7 on screw rod 6 is provided with screw in the slide block 7, and the external screw thread on internal thread on this screw and the screw rod 6 matches; By above-mentioned internal thread and externally threaded cooperation, slide block 7 can horizontally slip along screw rod 6.The lower guideway 10 that parallels with screw rod 6 is set below screw rod 6, on lower guideway 10, be provided with the linear bearing 9 that slides and link to each other with lower guideway 10, bar shaped scrubbing brush 8 is between screw rod 6 and lower guideway 10, the upper end of bar shaped scrubbing brush 8 and slide block 7 are fixedly linked, and the lower end of bar shaped scrubbing brush 8 and linear bearing 9 are fixedly linked; Bar shaped scrubbing brush 8 is provided with fur.

Left end at lower guideway 10 is provided with left lateral journey switch 13, is provided with right lateral journey switch 14 at the right-hand member of lower guideway 10; Left lateral journey switch 13, right lateral journey switch 14 and drive motors 2 link to each other with controller 1 signal respectively; Clear for drawing, this signal annexation has been done to omit in Fig. 1 and has been handled.Below lower guideway 10, be provided with powder ash-pit 12.

During the actual use of this automatic blackboard cleaning device, as shown in Figure 2; Fixedly install blackboard 100 on body of wall, make screw rod 6 be positioned at the top of blackboard 100, lower guideway 10 is positioned at the below of blackboard 100, and screw rod 6, blackboard 100 and lower guideway 10 are parallel to each other, thereby makes the fur of bar shaped scrubbing brush 8 can be over against blackboard 100; Motor mount 3, screw rod mount pad 5, guide rail mount pad 11 and powder ash-pit 12 all are fixedly linked with body of wall.The concrete course of work is as follows:

When the needs blackboard wiping, press the start button on the controller 1, drive motors 2 is rotated, drive motors 2 drives screw rod 6 by shaft coupling 4 and rotates together, slide block 7 moves from left to right along screw rod 6, from left to right blackboard 100 is carried out wiping thereby drive bar shaped scrubbing brush 8; Meanwhile, linear bearing 9 moves from left to right along lower guideway 10 under the drive of bar shaped scrubbing brush 8, and when linear bearing 9 contacted with right lateral journey switch 14, right lateral journey switch 14 sent a signal to

controller

1,2 counter-rotatings of controller 1 command driven motor.

When drive motors 2 counter-rotatings, slide block 7 just moves from right to left along screw rod 6, from right to left blackboard 100 is carried out wiping once more thereby drive bar shaped scrubbing brush 8; Meanwhile, linear bearing 9 moves from right to left along lower guideway 10 under the drive of bar shaped scrubbing brush 8, and when linear bearing 9 contacted with left lateral journey switch 13, left lateral journey switch 13 sent a signal to controller 1, and controller 1 command driven motor 2 quits work; The whole release that erases the board.At this moment, bar shaped scrubbing brush 8 is positioned at the left side of blackboard 100, for task is ready down.The chalk dust that powder ash-pit 12 is produced when being used to collect bar shaped scrubbing brush 8 blackboard wipings 100.

At last, it is also to be noted that what more than enumerate only is a specific embodiment of the present utility model.Obviously, the utility model is not limited to above embodiment, and many modification can also be arranged.All modification that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
