Problems solved by technology

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the need to increase the volume of the hydraulic oil tank and adopt a gear pump with a larger displacement in order to ensure the supply of hydraulic oil after the hydraulic system in the prior art increases the components to be driven, so that the cost is too high Therefore, even after increasing the number of components to be driven, without increasing the volume of the hydraulic oil tank and without using a gear pump with a larger displacement, the supply of hydraulic oil can be guaranteed, so the cost of hydraulic pressure is lower. system

Abstract

The invention provides a hydraulic system, a motor sweeper hydraulic system and a motor sweeper with the motor sweeper hydraulic system. The hydraulic system comprises a hydraulic oil tank, a hydraulic pump, an oil conveying pipe, an oil return pipe, at least one oil pipe and a plurality of hydraulic motors. The hydraulic oil tank is provided with a hydraulic oil inlet and a hydraulic oil outlet. The hydraulic pump is provided with a hydraulic pump inlet and a hydraulic pump outlet, and the hydraulic pump inlet is communicated with the hydraulic oil outlet through a pipe. The oil conveying pipe is communicated with the hydraulic pump outlet. The oil return pipe is communicated with the hydraulic oil inlet. The two ends of the oil pipes are communicated with the oil conveying pipe and the oil return pipe respectively. At least two hydraulic motors are connected to one oil pipe in series. Compared with a hydraulic system in the prior art, according to the hydraulic system, the number of branches from the oil conveying pipe to the oil return pipe is lowered, the requirements for the hydraulic oil tank and a gear pump are lowered, and equipment cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of hydraulic systems, in particular to a hydraulic system, a cleaning vehicle hydraulic system and a cleaning vehicle equipped with the hydraulic system. Background technique [0002] Sweeping vehicles are mainly used for road rubbish cleaning on urban roads, and generally include multiple side sweeping discs driven by hydraulic motors, and suction cups connected to fans. When the hydraulic motor drives the side sweeping disc to work, the side sweeping disc sweeps the garbage to the vicinity of the suction cup, and the fan rotates to make the suction cup generate negative pressure to suck out the garbage. When the road conditions are poor or there is too much rubbish on the road surface, it is necessary to add a rolling sweeper to continue sweeping the rubbish that has not been sucked up by the suction cup until the sucker completely sucks all the rubbish away. [0003] In the hydraulic system of the cleani...
