Synchronous belt 44 rotates together, and brush plate 45 constantly can forward clean the dust at 92 middle part of pole plate.Brush plate 45 is with same
Step band 44, which rotates together, encounters flexible block 46, and when continuing rotation disengaging flexible block 46 forward, brush plate 45 swings energy
Preferably clean pole plate 92.Elastic balloon 7 is equipped between first brush holder support 1 and the second brush holder support 2, when the first brush holder support 1 and the second brush holder support 2
Angle constantly changes, and elastic balloon 7 is squeezed at this time, elastic balloon 7 toward 8 gas transmission of gas chamber, air-flow make piston 9 forward before
Into air-flow is vented outward by the stomata 91 of 8 bottom of gas chamber, and a gas vent 91 of 8 bottom of gas chamber is opened one by one, air-flow
The dust at 92 middle part of pole plate is gradually purged can forward.When dedusting mechanism 4 moves to lug edge, No.1 is flexible
Bar 61 travels forward the top for pushing sliding panel 63 to arrive lug, and then No. two 62 Work Promote racks 64 of telescopic rod move forward,
And then the rotation of gear 65 drives cleaning brush 68 to laterally rotate, and the dust among lug is cleaned to both sides, it is single to avoid cleaning
Member 6 makes lug edge deformation from one end of lug to other end cleaning, and cleaning brush 68, which laterally rotates, encounters elastic baffle 11, bullet
Property baffle 11 make cleaning brush 68 swing increase clean effect.
The basic principles, main features and advantages of the invention have been shown and described above.The technical staff of the industry should
