The invention belongs to the technical field of
greening maintenance, and particularly relates to a
trunk whitewashing method for a road
green belt. A
trunk whitewashing device is adopted for cooperatively implementing the method and comprises a base, wherein idler wheels and a push frame are installed on the base, two installing plates are installed on the base, strip-shaped slide grooves are formed in the side faces of the installing plates, and two first air cylinders are in sliding fit with each other in the strip-shaped slide grooves. Semicircular installing frames are fixedly connected to the ends of the first air cylinders, semicircular slide grooves are formed in the upper surfaces of the semicircular installing frames, and have the identical
radius and are matched with each otherin end, vertical n-shaped installing frames are in sliding fit with each other in the semicircular slide grooves, and sweeping mechanisms and brushing mechanisms are installed on the n-shaped installing frames. Before trunks of trees on the
green belt are whitewashed by means of the
trunk whitewashing method, hairbrush rollers rotating at a high speed conduct annular sweeping on the surface of
bark in the vertical direction to clean away
moss and other inquilines growing in gaps of the
bark, in this way, a whitewashing agent sufficiently enters the gaps of the
bark to kill pests hidden in treegaps, and the whitewashing effect is improved.
