The invention discloses a hydraulic system of a motor sweeper and the motor sweeper. The hydraulic system of the motor sweeper comprises a box body and a rear door rotationally connected to the box body, an opening and closing oil cylinder is arranged on the rear door, a lifting oil cylinder is arranged on the box body, the opening and closing oil cylinder is connected to a rear door opening and closing pipeline, the lifting oil cylinder is connected to a box body lifting pipeline, the rear door opening and closing pipeline and the box body lifting pipeline are connected in parallel and then are connected into a dumping pipeline, a dumping control valve group is arranged on the dumping pipeline, and the hydraulic system further comprises a sequence control valve arranged on the rear door opening and closing pipeline and the box body lifting pipeline so as to control the opening and closing oil cylinder and the lifting oil cylinder to be sequentially opened. According to the hydraulic system of the motor sweeper, linkage control over lifting of the box body and opening of the rear door is achieved through a control valve group, misoperation of a user is avoided, the user cannot complete lifting operation under the condition that the box body is fully loaded, and safety is improved.
本发明公开了一种清扫车液压系统及清扫车，其中清扫车液压系统,包括箱体和转动连接在箱体上的后门，后门上设有启闭油缸，箱体上设有举升油缸，启闭油缸连接至后门启闭管路，举升油缸连接至箱体举升管路，后门启闭管路和箱体举升管路并联后接入倾倒管路，倾倒管路上设有倾倒控制阀组，还包括设置在后门启闭管路和箱体举升管路上的顺序控制阀，以控制启闭油缸和举升油缸顺序开启。本发明所述的清扫车液压系统通过控制阀组实现箱体举升和后门开启的联动控制，避免用户出现误操作，使用户无法在箱体满载的情况下完成举升操作，提高安全性。
