The invention relates to a solar driving device of a coil type automatic walking sprinkler. The device comprises a coil type sprinkler, wherein the coil type sprinkler is provided with a solar panel, a light illumination sensor, a rotary mechanism, a driving motor, a speed reducer, a speed sensor and the like. The device has the advantages that the device is driven by a motor which can be powered by solar energy, so the defect of high energy consumption of common water turbine driving of the general sprinkler is overcome; a storage battery is powered by the solar panel, so the complicated condition of a power supply line overhead a farmland is avoided; the solar panel is provided with an intelligent sun tracing system, the solar panel is enabled to automatically rotate and adjust the angles, and the higher photovoltaic power generation efficiency of the solar panel is realized; a hose pipe is provided with the speed sensor, a closed loop control system is controlled through speed to enable the hose pipe of a coiling vehicle to move at constant speed during pipe coiling, the speed difference caused by the winding layering of the hose pipe is avoided, and the uniform distribution of water spraying amount is ensured; the defects of high energy consumption, heavy weight, nonuniform distribution of water spraying amount and the like of the existing coil type sprinkler are overcome, and the solar driving device is a novel green, energy-saving and environment-friendly type intelligent driving device.
