The working principle of a road sweeper mainly includes the following aspects:
Cleaning device: Road sweepers are usually equipped with multiple sweeping brushes, including front sweeping brushes, side sweeping brushes, and rear suction nozzles. The front sweeping brush is responsible for sweeping garbage from the outside to the inside towards the bottom of the car, while the side sweeping brush is responsible for cleaning garbage in corners and along the roadside. These brushes are lifted and extended outward through a hydraulic system, driven by a hydraulic motor for high-speed rotation.
Vacuum system: The vacuum system of the road sweeper consists of a fan and a suction nozzle. The fan generates negative pressure through high-speed operation and sucks the garbage on the road into the garbage bin. The suction nozzle design has a height adjustable function, which can adjust the reasonable gap between the suction nozzle and the road surface as needed to ensure efficient suction effect.
Water spray dust reduction system: To control dust, road sweepers are usually equipped with water spray devices. The spray rack generates water mist through the electric diaphragm pump, and spray is used to reduce dust during the cleaning process to further ensure the cleaning effect and the cleanness of the environment.
The structure of a road sweeper includes the following main parts:
Chassis: The chassis of a road sweeper is its basic structure, and common chassis brands include Dongfeng, Foton, Isuzu, Jianghuai, etc. The choice of chassis directly affects the performance and applicability of the vehicle.
Cleaning device: The cleaning device includes a front sweeping brush, a side sweeping brush, and a rear suction nozzle. The front sweeping brush is responsible for sweeping garbage from the outside to the inside towards the bottom of the car, while the side sweeping brush is responsible for cleaning garbage in corners and along the roadside. These brushes are lifted and extended outward through a hydraulic system.
Vacuum system: The vacuum system consists of a fan and a suction nozzle. The fan generates negative pressure through high-speed operation and sucks the garbage on the road into the garbage bin. The nozzle design has a height adjustable function, which can adjust the reasonable gap between the nozzle and the road surface according to needs.
Water spray dust suppression system: the water spray dust suppression system generates water mist through the water spray rack and the electric diaphragm pump, and spray dust suppression is carried out during the cleaning process to control dust.
Electro hydraulic control system: The electro-hydraulic control box controls all key operations of the road sweeper, and the driver can easily control the lifting and rotation of the left and right sweeping discs, as well as the lifting and lowering of the suction nozzle, the opening and closing of the garbage bin rear door, etc. through it
