Problems solved by technology
[0005] At present, road sweepers generally use springs to prevent the bristles from wearing out quickly and causing poor cleaning quality due to excessive pressure on the ground due to their own gravity. This method requires manual adjustment of the springs, and the adjustment needs to be based on experience. The adjustment frequency is high, time-consuming and labor-intensive, which greatly reduces the working efficiency of the road sweeper

Embodiment Construction
[0015] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0016] like figure 2 and 3 As shown, a floating hydraulic system of a road sweeper working device includes a fuel tank 1, a hydraulic pump 2, a first solenoid valve 3, an electromagnetic proportional pressure regulating valve 4, a second solenoid valve 5, a brush lifting cylinder 6, and a suction cup lifting cylinder 7. The third electromagnetic valve 8 and the reversing valve 9.
[0017] The functions of each part are as follows:
[0018] Oil tank 1: store hydraulic oil.
[0019] Hydraulic pump 2: Provide hydraulic oil for hydraulic action.
[0020] The first solenoid valve 3: It can be used to select whether the brush (and suction cup) works in floating mode or lifting mode.
[0021] El...

The invention discloses a floating hydraulic system of a road sweeper work device. The floating hydraulic system comprises an oil tank, a hydraulic pump, a first electromagnetic valve, an electromagnetic proportional pressure regulating valve, a second electromagnetic valve, a sweeping brush lifting oil cylinder, a suction cup lifting oil cylinder and a reversing valve. The oil tank is connected with the hydraulic pump, and the hydraulic pump is connected with the first electromagnetic valve. The first electromagnetic valve is connected with the electromagnetic proportional pressure regulating valve, the second electromagnetic valve and the reversing valve. The electromagnetic proportional pressure regulating valve is connected with the second electromagnetic valve and the oil tank. The second electromagnetic valve is connected with the sweeping brush lifting oil cylinder and the suction cup lifting oil cylinder. The sweeping brush lifting oil cylinder is connected with the reversing valve. The suction cup lifting oil cylinder is connected with the reversing valve and the oil tank. The reversing valve is connected with the oil tank. According to the floating hydraulic system, oil cylinder floating pressure regulation can be achieved by regulating the electromagnetic proportional pressure regulating valve; and in the use process, the electromagnetic proportional pressure regulating valve is externally connected with a control device, a driver can regulate the contact force between a sweeping brush and the ground in a cab without getting off for operation, and work efficiency is greatly improved.
Description
technical field [0001] The invention relates to a floating hydraulic system of a road sweeper working device, which belongs to the field of sanitation machinery and equipment. Background technique [0002] With the development of domestic society, human beings have higher and higher requirements for living environment and environmental protection. Electric road sweepers are used more and more frequently because of their low noise and zero emission. [0003] During the operation of the road sweeper, the pressure of the sweeping brush of the road sweeper on the ground affects the wear speed of the bristles and the cleaning quality. like figure 1 As shown, the gravity G of the sweeping brush (and the bracket for installing the sweeping brush), the force Fn of the ground facing the sweeping brush and the force F of the oil cylinder are balanced. Wherein, the ground-to-sweeping force Fn is the ground pressure. [0004] When the cleaning quality is poor due to the high adhesion...
