Description

Technical Field

[0001] The utility model relates to the technical field of cleaning tools, in particular to a roller-brush linkage conveying structure for cleaning garbage. Background Art

[0002] The road sweeper is a new type of efficient cleaning equipment that integrates road sweeping, garbage collection and transportation. It is a type of equipment suitable for all-round cleaning of factories, highways, parks, squares and other roads, and is suitable for cleaning operations in various climates and different dryness of roads.

[0003] The cleaning system of a road sweeper is generally mainly a disc brush, which is distributed at both ends of the front of the road sweeper and is mainly used to clean the garbage on both sides and concentrate it in the middle of the vehicle body; in addition, many road sweepers are equipped with high-power fans, which provide suction to suck the garbage cleaned by the disc brush into the filter and separate the solid impurities in the sucked gas. Since the cleaning range of the disc brush is limited, in order to expand the cleaning area and improve the cleaning effect, the current road sweepers also use roller brushes for dust removal and impurity transportation.

[0004] In actual application, the sweeper needs to fold and lower the roller brush. In the prior art, the roller brush is usually folded and lowered through a large hydraulic device. Due to its long stroke, it takes a long time to fold and lower, and the work is large. Sometimes the roller brush only needs to be folded a little, such as when crossing a puddle. The use of a large hydraulic device causes waste and is not flexible enough. In addition, the outer surface of the roller brush is provided with dense hard bristles. After long-term use, impurities adhere to it, making it difficult to clean, and there is room for improvement. Utility Model Content

[0026] The working principle of the utility model is as follows: when the roller brush 15 only needs to be slightly lifted to facilitate crossing puddles and muddy sections, the hydraulic rod 2 13 operates to drive the transverse mounting member 11 to rotate at the support arm 6, thereby changing the inclination angle of the roller brush 15 and achieving a slight lift; when the operation is completed and the roller brush 15 needs to be retracted upward significantly, the hydraulic rod 1 7 operates to cause the support arm 6 to rotate around the side mounting plate 5, thereby driving the roller brush 15 to be retracted upward through the support arm 6; when the roller brush 15 needs to be cleaned, first the motor 21 drives the hollow shaft 24 to rotate through the power rod 22 and the synchronous belt 23, that is, drives the roller brush 15 to rotate, and then opens the valve, and the water in the water tank 17 is transported to the hollow shaft 20 through the water pipe 24, and the water is thrown out through the leaking hole 28 and the through hole 19, and the water flows out between several bristles. The roller brush 15 rotating at a high speed can remove impurities in the process of throwing out the water, complete self-cleaning, and avoid the wear of the bristles due to the accumulation of impurities for a long time and the influence on the roller brush operation effect.
