Abstract
The invention discloses a triple helix rod car cleaner for a U-shaped tramcar. A triple helix rod structure is adopted, two helix rods at the bottom are separated from the middle, and the two ends adopt helix rods with different rotating directions, accordingly, when the helix rods rotate, loose ash (or marl) is pushed to the middle by the two ends, and all loose ash (or plaster) is pushed to the middle as much as possible in order to improve efficiency. A double helix rod structure is adopted, and the ash (or marl) pushed to the middle is lifted by a lifting helix rod 8 and is drained to the outside of the tramcar. The car cleaner, in particular to the triple helix rod car cleaner for the U-shaped tramcar, completes the car cleaning work under the premise that any damage to the tramcar is not generated, is flexible and convenient, has high efficiency, and can clean vast majority of marl adhered in the tramcar.
Description
Technical field
