On the basis of embodiment 4, as shown in fig. 15 and 16, the power mechanism 8 is further included, the power mechanism 8 includes a connecting rod 81, a pulling rope 82, a second connecting block 83, pulley 84, slider 85 and slide rail 86, the equal riveting of the left and right sides of third connecting plate 71 has connecting rod 81, all be connected with stay cord 82 on two connecting rod 81, the middle part of two second ventilating board 52 front sides all has second connecting block 83 through the screw rigid coupling, the equal rotary type in front side of two second connecting block 83 is connected with two pulleys 84, stay cord 82 walks around two pulleys 84 of homonymy, the front side of two second ventilating boards 52 all has connected slide rail 86 through bolted connection, all be connected with slider 85 on two slide rails 86 slidingly, the bottom at two corresponding sliders 85 is connected respectively to the other end of two stay cords 82, second connecting block 83 and slider 85 contact, first connecting block 65 rebound can contact with slider 85.
In the process of cleaning dust on the surface of the second vent plate 52, the first connecting block 65 drives the sliding block 85 to move upwards along with the first connecting block, under the sliding fit action of the sliding block 85 and the sliding rail 86, the pulling rope 82 slides upwards along with the first connecting block, under the wrapping action of the pulling rope 82 and the two pulleys 84, the pulling rope 82 drives the connecting rod 81 to slide downwards along with the first connecting block, so that dust impurities on the V-shaped plate 44 can be cleaned conveniently, after the dust impurities on the V-shaped plate 44 are cleaned, the first connecting block 65 drives the sliding block 85 to slide downwards along with the first connecting block, the pulling rope 82 is loosened along with the first connecting block, under the elastic force action of the spring 72, the third connecting plate 71 drives the connecting rod 81 to reset, so that the dust impurities remained on the V-shaped plate 44 can be cleaned conveniently, and convenience is provided for the operation of cleaning the dust impurities on the V-shaped plate 44.
While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. The scope of the following claims is to be accorded the broadest interpretation so as to encompass all such modifications and equivalent structures and functions.
