Sweeping disc hydraulic control system and road sweeping operation vehicle
The invention discloses a sweeping disc hydraulic control system and a road sweeping operation vehicle, the sweeping disc hydraulic control system comprises an oil supply device, a sweeping disc driving device, a first reversing valve and a second reversing valve, and the sweeping disc driving device comprises a first driving piece and a second driving piece; a first oil inlet of the first reversing valve is communicated with the oil supply device, a first working oil port is communicated with the first driving part, and the first reversing valve is used for selecting one of the first working oil port and the closed oil port to be communicated with the first oil inlet; a second oil inlet of the second reversing valve is communicated with the oil supply device through the second driving piece, the second working oil port is communicated with the first driving piece, the third working oil port is connected with the oil return tank, and the second reversing valve is used for selecting one of the second working oil port and the third working oil port to be communicated with the second oil inlet. The sweeping disc hydraulic control system can supply oil to the first driving part and/or the second driving part, and the oil only needs to flow through the first reversing valve or the second reversing valve, so that the oil pressure loss is greatly reduced, and the cost is reduced.
本发明公开一种扫盘液压控制系统及道路清扫作业车，扫盘液压控制系统包括供油装置、扫盘驱动装置、第一换向阀和第二换向阀，扫盘驱动装置包括第一驱动件和第二驱动件；第一换向阀的第一进油口与供油装置连通，第一工作油口与第一驱动件连通，第一换向阀用于在第一工作油口和封闭油口中选择一者与第一进油口连通；第二换向阀的第二进油口通过第二驱动件与供油装置连通，第二工作油口与第一驱动件连通，第三工作油口连回油箱，第二换向阀用于在第二工作油口和第三工作油口中选择一者与第二进油口连通。扫盘液压控制系统能向第一驱动件和/或第二驱动件供油，且油液仅需流经第一换向阀或第二换向阀，大幅减少了油压耗损并降低了成本。
