Abstract

The utility model belongs to the technical field of urea solutions, and particularly discloses a urea solution spraying device which comprises a solution cylinder, a grab handle is arranged on the outer surface of the solution cylinder, a liquid injection valve is arranged at the top of the solution cylinder, a miniature water pump is fixedly installed at the bottom of the solution cylinder, and the output end of the solution cylinder is fixedly communicated with a communication chamber. The output end of the communicating chamber fixedly communicates with a straight pipe, an atomizing nozzle is arranged at the end, away from the communicating chamber, of the straight pipe, and a liquid control mechanism is arranged on the communicating chamber. According to the urea solution spraying device, the grab handle is held by hand to lift the spraying device, the liquid control mechanism is matched with the micro water pump to enable a urea solution to be sprayed out of the atomization spray head, the spraying amount of the solution is accurately controlled through the liquid control mechanism, the spraying amount can be adjusted according to the requirements and growth stages of different crops, and the problem of excessive or insufficient fertilization is avoided; the fertilizing effect is improved to the greatest extent, and the urea solution is accurately sprayed in a point-to-point manner.
