Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning brush disassembly and assembly, and particularly relates to a quick-release structure for a cleaning brush of a sanitation vehicle. Background Art

[0002] A sanitation vehicle is a special vehicle used for urban appearance tidying and cleaning. A cleaning vehicle is a new and efficient cleaning device integrating road surface cleaning, garbage collection and transportation. It is a vehicle type suitable for all-round cleaning work on road surfaces such as factories, roads, parks, and squares. This new vehicle type can complete ground cleaning, curb cleaning, curb washing, and sprinkling on the ground after cleaning at one time, and is suitable for cleaning operations in various climates and on different dry road surfaces.

[0003] After the cleaning brush set on a sanitation cleaning vehicle is used for a period of time, when the cleaning brush is severely worn, the cleaning brush needs to be replaced. However, usually, the cleaning brush is sleeved on the outside of one end of a transmission shaft, and then the cleaning brush is fastened by a nut. Therefore, when disassembling and installing the cleaning brush, a wrench needs to be placed under the cleaning brush to unscrew or fasten the nut. Since the position of the cleaning brush set on many sanitation vehicles is relatively low, there is a small reserved space, which will affect the screwing of the nut, thus making it inconvenient to disassemble the cleaning brush. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a quick-release structure for a cleaning brush of a sanitation vehicle to solve the technical problem of inconvenient disassembly of the cleaning brush proposed in the background art.
