Washing and sweeping vehicle applying joint one-way valve technology

The utility model discloses a cleaning and sweeping vehicle applying the joint one-way valve technology, which comprises a transmission mechanism and a vehicle body, the transmission mechanism is fixed at the front end of the vehicle body, and a working motor for providing power for the transmission mechanism is fixed at the upper end of the transmission mechanism. When a working motor drives a main gear to rotate through a motor shaft, due to the fact that every two adjacent gears in a transmission frame are in a meshed state, a first gear and a second gear start to rotate under the action of a second auxiliary gear and a first auxiliary gear respectively, the rotation directions of the first gear and the second gear are opposite, and at the moment, the first gear and the second gear are driven to rotate. And under the driving of the rotating rod, the two sweeping discs can quickly rotate, so that the sweeping discs can gather garbage on the road surface towards the lower end of the vehicle body, the roller
