The specific embodiment
Below in conjunction with accompanying drawing, the present invention is done further and explained.
As shown in Figure 1, 2, the present invention's two dimension automatic blackboard cleaning device comprises travel mechanism and Wiping mechanism, and described travel mechanism comprises mobile platform 1, the second motor, tooth bar 3, travelling gear 4, gear shaft rod 5, support bar 2, the second described motor is used for driving tooth bar 3, described tooth bar 3 is symmetrically distributed in the both sides up and down of blackboard, and be connected with a joggle with travelling gear 4, described gear shaft rod 5 is positioned at described travelling gear 4 axle center, and the connecting rod by both sides 14 is connected with described support bar 2 respectively, between described connecting rod 14 and described gear shaft rod 5, be hinged, and described support bar 2 is rectangular, described support bar 2 is connected with described mobile platform 1 length direction two ends, described mobile platform 1 is positioned at blackboard outer side surface, and parallel with blackboard surface, described Wiping mechanism comprises the first motor, gear drive and executing agency, the first motor is for driven wheel transmission mechanism, described gear drive is positioned on described mobile platform 1, described gear drive comprises driving wheel 8, gear wheel 9 with driving wheel engagement, the partial gear 10 coaxial with gear wheel 9, respectively with the thrust gear 11 being arranged symmetrically and the idle pulley 12 of partial gear 10 engagement, and with the secondary thrust gear 13 of idle pulley 12 engagement, described driving wheel 8 and gear wheel 9 are positioned at same plane, described partial gear 10, thrust gear 11, idle pulley 12 and secondary thrust gear 13 are positioned at same plane, and described partial gear 10 is by forming by toothed portion with without toothed portion, and there is toothed portion and respectively account for half without toothed portion, and partial gear 10 is by having the unidirectional and described thrust gear 11 of toothed portion or idle pulley 12 engagements, described executing agency comprises two identical connecting rods 6 and blackboard eraser 7, one end of two described connecting rods 6 is connected with secondary thrust gear 13 with described thrust gear 11 respectively and synchronizes rotation with described thrust gear (11) and secondary thrust gear (13), the other end of two connecting rods 6 is connected with the two ends of blackboard eraser 7 respectively, and described two connecting rods 6 be arranged in parallel.
While erasing the board, first the first driven by motor tooth bar 3 moves horizontally along blackboard length direction, by the engagement with gear 4, with nutating gear 4, the along continuous straight runs on tooth bar 3 rolls tooth bar, because connecting rod 14 and support bar 2 are affixed, make to support 2 and move horizontally together with following gear 4 by connecting rod 14 with gear shaft rod 5, thereby realize the translation of the mobile platform 1 affixed with support bar 2.
The second driven by motor driving wheel 8 rotates simultaneously, driving wheel 8 drives the rotation of gear wheel 9 by engagement, the number of teeth of gear wheel 9 is greater than the number of teeth of driving wheel 8, therefore transmission speed declines, play decelerating effect, power is delivered on coaxial partial gear 10 after the deceleration of gear wheel 9, and partial gear 10 drives thrust gear 11 to be rotated counterclockwise half cycle within upper half cycle that turns clockwise, thereby drivening rod 6 upwards swings; Partial gear drives idle pulley 12 to be rotated counterclockwise within lower half cycle that turns clockwise, idle pulley 12 drives secondary thrust gear 13 to turn clockwise again, thereby thereby drivening rod 6 has been realized the up and down reciprocatingly swing of connecting rod to lower swing, the idle pulley 12 here plays the effect of translational movement direction.
