Description

A ball-cage type coupling dual-fan power transmission mechanism and a high-speed road sweeper Technical Field

[0001] This utility model relates to the technical field of road sweeping equipment, and in particular to a ball cage type coupling dual fan power transmission mechanism and a high-speed road sweeper. Background Technology

[0002] With the rapid development of mechanized road sweeping in my country, large-scale urban road sweeping operations are now primarily carried out by dedicated road sweeping vehicles. During operation, these vehicles sweep road debris to a range in front of a suction nozzle using a sweeping disc. As the nozzle passes, the suction provided by a blower draws the debris into a garbage bin. For example, Chinese patent CN205059176U discloses a road sweeping vehicle; however, this patent uses a single-fan structure, resulting in relatively weak suction due to the single fan.

[0003] Therefore, to address the above problems, a ball-cage type coupling dual-fan power transmission mechanism and a high-speed road sweeper are proposed to solve these problems. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by developing a ball-cage type coupling dual-fan power transmission mechanism and a high-speed road sweeper. This invention can drive two fans to sweep the road surface.

[0006] The power unit outputs power to the first blower, which then transmits the power to the second blower via a ball-cage coupling. The first and second blowers work together to sweep the road surface below, improving sweeping efficiency.

[0007] Preferably, a first suction duct is provided on the first fan, and multiple first filters are provided on the first suction duct.

[0009] The first and second fans are connected to the first and second collection boxes, respectively. The operation of the first and second fans creates negative pressure in the first and second collection boxes, which then collects the garbage on the road through the first and second collection pipes and puts it into the first and second collection boxes.

[0010] Preferably, the first fan is connected to the first pulley, the first pulley is connected to the second pulley via a drive belt, the second pulley is mounted on the engine, the engine is mounted on the mounting base, the base is also mounted on the mounting bracket, the mounting bracket is mounted on the tensioning wheel, and the tensioning wheel presses against the outside of the drive belt.

[0017] The effects provided in the utility model description are merely those of the embodiments, and not all the effects of the utility model. The above technical solution has the following advantages or beneficial effects:

[0018] The power unit outputs power to the first blower, which transmits the power to the second blower through a ball cage coupling.
