Embodiment 1
As it is shown in figure 1, a kind of self-cleaning crawler belt device for blackboard eraser, including box body 7, guide rail bracket, ash-swabbing device, deashing dress
Put, store up apparatus for ash；Guide rail bracket includes rolling wheel guide rails 3 and is horizontally installed on the guide wheel 2 at rolling wheel guide rails 3 two ends；Rolling wheel guide rails 3 is in card
Channel-shaped；
As shown in Figure 4 and Figure 5, ash-swabbing device is a crawler type rub body 12, is arranged at the inside of box body 7, and it includes snag
14, track chain 15 and crawler belt gear 8；As in figure 2 it is shown, the middle part of crawler belt gear 8 is coaxial therewith being fixedly installed crawler belt gear
Wheel shaft 17；Crawler belt gear hub 17 through the both sides of box body 7, and and box body 7 between be provided with bearing；
As shown in Figure 4 and Figure 6, deashing device is a brush body 13, is arranged in box body 7；The surface of deashing device brush body 13
For bristle 18；Brush body 13 is fixed on box body 7 on the internal face relative with snag 14 in crawler type rub body 12；As it is shown in fig. 7, brush
Hair 18 is made up of some rigid plastics taper pin hairs；Use the bristle 18 that rigid plastics taper pin hair is made, on the one hand compare gold
The cost of material is low for genus, and on the one hand hard material can improve the effect scraping chalk dust from snag 14, and on the one hand chalk dust can
Falling to drawing and pulling type stored ash box 11 with the gap between each pin hair, one end that another further aspect taper pin hair is thick is fixed on brush body 13
On more firmly, stable, thin one end is better for striking off the chalk dust in snag 14, improves ash-removal effect；
As it is shown in figure 1, storage apparatus for ash is arranged on the bottom of box body 7, storage apparatus for ash is movable drawing and pulling type stored ash box 11, takes out
Being provided with stored ash box body handle 16 on pull-type box body 11, convenient extraction out at any time by drawing and pulling type box body 11 clears up chalk dust therein；
As shown in figures 1 and 3, box body 7 two ends are each provided with a wheel shaft 5；It is provided with bearing between wheel shaft 5 and box body 7；
Respectively being fixedly installed two rollers 4 on two wheel shafts 5, roller 4 coordinates with the rolling wheel guide rails 3 of card channel-shaped, can block at rolling wheel guide rails 3
Groove moves up and down, it is to avoid roller 4 swings；The end of a piece wheel shaft 5 is additionally provided with the first meshing gear 10；Caterpillar teeth
Wheel wheel shaft 17 one end is stretched out outside box body 7, and this end is fixed with the second meshing gear 9；Second meshing gear 9 and the first meshing gear 10
Engagement；Roller 4 diameter is equal to the diameter of the first meshing gear 10, and the diameter of crawler belt gear 8 is straight more than the second meshing gear 9
Footpath；When roller 4 moves, its maximum line velocity, angular velocity are all equal with the first meshing gear 10, the line that the second meshing gear 9 rotates
The linear velocity that speed rotates equal to the first meshing gear 10, owing to the diameter of crawler belt gear 8 is more than the straight of the second meshing gear 9
Footpath, so the linear velocity that the linear velocity that crawler belt gear 8 rotates rotates more than the second meshing gear 9 such that it is able to make box body 7 in fortune
Drive crawler belt gear 8 to produce speed difference time dynamic, and crawler belt gear 8 drives the relative blackboard movement velocity of snag 14 more than box body 7
Movement velocity；Such as when box body 7 moves downward with speed v, through the second meshing gear 9 and transmission of the first meshing gear 10
To crawler type rub body 12 move downward time, the speed that crawler type rub body 12 moves downward is 2v, at this time can improve blackboard and remove
The efficiency of ash, is equivalent in the case of box body 7 moves downward distance S, and snag 14 has been moved 2S relative to blackboard, say, that wiping
Hair 14 is to the blackboard-cleaning at least twice in S distance, thus improves wiping ash efficiency.
The using method of a kind of self-cleaning crawler belt device for blackboard eraser, comprises the steps:
S1. guide rail bracket upper block 2 is fixed on blackboard on blackboard guide rail 1, makes on blackboard, need wiping powder
In place of ash；
The most hand-held box body 7 makes its roller 4 be combined with rolling wheel guide rails 3, and crawler type rub body 12 contacts with blackboard surface simultaneously；
S3. box body 7 in step S2 is promoted so that it is roller 4 moves from the top down along rolling wheel guide rails 3；The rotation of roller 4 drives
The wheel shaft 5 being secured to connect rotates, and axle wheel 5 rotation drives the first meshing gear 10 being secured to connect to rotate, and first nibbles
Closing rotating of gear 10 drives the second meshing gear 9 engaged to reversely rotate, rotarily driving and it of the first meshing gear 9
The fixing crawler belt gear hub 17 connected rotates, and rotating of crawler belt gear hub 17 drives the crawler belt gear 8 being secured to connect
Rotating, the rotation of crawler belt gear 8 drives and is wrapped in track chain 15 thereon and snag 14 relative to blackboard mantle friction slip；
S4. the snag 14 slided relative to blackboard mantle friction in step S3 with walk around after crawler belt gear 8 relative to brush body
The bristle 18 of 13 moves upward, and in snag 14, chalk dust falls to store up in apparatus for ash 11 through the brushing of bristle 18；
S5. box body 7 transverse shifting box body 7 again after blackboard top is pushed to blackboard bottom in step S3, repeats step S3
And S4, until blackboard wipes.
The method of the present embodiment can improve efficiency and the effect of blackboard-cleaning, and the rolling by box body 7 upper roller 4 is final
Snag 14 is driven to move relative to blackboard, it is achieved the effect of blackboard wiping, and by the first meshing gear 10 and the second engaging tooth
Take turns 9 chronotropic actions, it is achieved that snag 14 is more than the box body 7 effect relative to blackboard movement velocity relative to blackboard movement velocity,
Thus increase wiping effect and wiping efficiency.
