Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of vehicles, and in particular relates to a cleaning vehicle hydraulic system and a cleaning vehicle for realizing linkage control of box body lifting and rear door opening. Background technique [0002] Sweeper is a special operation vehicle used for urban road cleaning. It creates negative pressure in the garbage bin through fan suction, and collects garbage into the garbage bin. The hydraulic system of the sweeper is a key technology of this type of vehicle. The stability and complexity of the hydraulic system of the sweeper affect the safety and maintenance efficiency of the system. [0003] The existing hydraulic system of the sweeper realizes the control of the hydraulic system of the sweeper through electronic control, resulting in a complex structure of the hydraulic system of the sweeper, which is prone to misoperation and poor in safety. Contents of the invention [0004] In order to solve the t...
