The invention discloses a green fence cleaning system. The system comprises a water distributor, a telescopic mechanism, a water distributor fixing base, a support, a water pipe, a ball valve, a waterpump, a power source, a connection wire, a controller, a control screen, tracks, sliding mechanisms, a camera and nozzles; the support is fixed to two sides of a chassis respectively, a power sourcewhich is carried by a water truck is used for driving the water pump, and then the water pipe which is provided with the ball valve is used for introducing water into the water distributor; clear water is atomized and sprayed out through the nozzles, the nozzles are of a multi-row structure and form the water distributor, and the water distributor is fixed in the water distributor fixing base; twosides of the water distributor fixing base are slidingly matched with the tracks which are fixed to two sides of the support through the sliding mechanisms, the telescopic mechanism which is arrangedin the same direction as the tracks is arranged between the support and the water distributor fixing base, and the telescopic mechanism is in an electric control driving or hydraulic control drivingmode. According to the green fence cleaning system, the technical aims can be achieved that a green belt cleaning mechanism is arranged on a sanitation vehicle with a water tank, a green belt is cleaned up, and water, time and labor are saved.
