Mowing device with blade collision prevention function for smart city gardens

The invention relates to the technical field of mowing equipment, in particular to a mowing device with a blade collision prevention function for smart city gardens. The mowing device comprises an equipment main body, a driving shaft is inserted in the equipment main body, and a gear I sleeves the outer part of the driving shaft and is positioned in the equipment main body; knife rests are fixedly connected to the left side face and the right side face of the driving shaft correspondingly, spray nozzles are inserted in the knife rests, and a fixing plate is fixedly connected to the lower surface of the equipment main body; blades on the driving shaft are integrally lifted when the tensile force of a second crank connecting rod and the restoring force of a delay spring frame are larger than the pressure of the driving shaft, so that the blades are prevented from colliding with stones, damage to the blades is avoided, and the service life of the blades can be well prolonged; water sprinkling treatment is conduc
