Second, the material conveying roller 341 drives the pushing member 35 to move synchronously, so that the inclined plate 352 pushes the material conveying roller 341 to the rear side, and when the pushing member 35 moves to be out of contact with the inclined plate 352, the pushing spring pushes the material conveying roller 341 to the front side, so that the material conveying roller 341 moves back and forth in a reciprocating manner, and therefore the material is rocked, and the overlapping phenomenon of the material is avoided.
Third, the material transporting roller 341 drives the pushing plate 361 thereon to move backward through the arc plate 36, so that the supporting rod 33 pushes the pushing plate 361 to the outside through the conical surface thereof, so that the pushing plate 361 drives the arc plate 36 at the corresponding position to move to the outside, and the ice and snow covered on the outside of the material transporting roller 341 is broken through the extending arc plate 36.
Fourth, the driven gear 342 is moved leftwards and simultaneously rotates clockwise through the engagement with the fixed rack 345, and at this time, the support rod 33 drives the material conveying roller 341 to move leftwards until contacting with the beating plate 371, so that the beating plate 371 beats on the outer side of the next material conveying roller 341, and further the ice and snow on the outer side of the material conveying roller 341 is smashed and falls.
Fifth, the material transporting roller 341 moving leftwards pushes the scraping plate 381 downwards, and meanwhile, the rotating material transporting roller 341 contacts with the scraping plate 381, so that the scraping plate 381 scrapes the adhered ice and snow on the material transporting roller 341, and the contact time of the material transporting roller 341 and the scraping plate 381 is prolonged through the contact of the material transporting roller 341 and the plurality of scraping plates 381, and the scraping effect of the ice and snow is guaranteed.
Sixth, the material transporting roller 341 rotated to the lower side drives the driven gear 342 at the corresponding position to move leftwards to engage with the rotating gear 391, at this time, the arc-shaped wiping plate 393 drives the cleaning cloth thereon to cover the lower side of the material transporting roller 341 attached to the corresponding position, and meanwhile, the executing motor 39 is started to drive the rotating gear 391 to rotate, so that the arc-shaped wiping plate 393 wipes the accumulated water outside the material transporting roller 341 through the cleaning cloth thereon.
While embodiments of the present invention have been shown and described above, it should be understood that the above embodiments are illustrative and not to be construed as limiting the invention, and that variations, modifications, alternatives, and variations may be made to the above embodiments by one of ordinary skill in the art within the scope of the invention, which is also intended to be covered by the present invention.
