Multi-directional pressurizing sprinkling irrigation device of plant protection unmanned aerial vehicle

Abstract

The invention relates to a multi-directional pressurizing sprinkling irrigation device of a plant protection unmanned aerial vehicle and relates to the field of sprinkling irrigation devices. The device comprises a liquid outlet cylinder, a liquid storage cylinder, a driving assembly, a pressure adjusting assembly, a liquid mixing assembly, a piston plate, a water inlet pipe, a water outlet pipe, a sprinkling irrigation head and a controller. The pressure adjusting assembly and the liquid mixing assembly are respectively arranged in a pressure adjusting chamber and a liquid mixing chamber. The piston plate is matched with the pressure adjusting assembly. The water inlet pipe is communicated with the liquid mixing chamber and the pressure adjusting chamber. The water outlet pipe communicates with the pressure adjusting chamber and the sprinkling irrigation head. The liquid storage cylinder is sleeved on the periphery of the liquid outlet cylinder. According to the device, multiple independent liquid storage chambers are arranged, through the effect of a liquid level sensor and in cooperation with manual judgment, on-site liquid preparation is achieved, the concentration is accurate, and the irrigation effect is guaranteed; the driving assembly is arranged, synchronous work of the pressure adjusting assembly and the liquid mixing assembly is achieved, on one hand, the pressure in the pressure adjusting chamber is adjusted, liquid inlet-liquid outlet circulation is achieved, meanwhile, the liquid outlet pressure and direction are guaranteed, and the purpose of efficient and low-energy-consumption irrigation is achieved.

Description

technical field [0001] The invention relates to the field of sprinkler irrigation devices, in particular to a multi-directional pressurized sprinkler irrigation device for a plant protection drone. Background technique [0002] Plant protection UAV, unmanned aerial vehicle, as the name implies, is an unmanned aircraft used for agricultural and forestry plant protection operations. Part of the composition, through ground remote control or navigation flight control, to achieve spraying operations, can spray chemicals, seeds, powder, etc. When the plant protection UAV performs high-altitude sprinkling irrigation, it is necessary to install the liquid storage tank with the UAV, and the liquid inside the liquid storage tank is sprayed out through the UAV control nozzle. The range and distance of spraying are small, which reduces the efficiency of sprinkler irrigation. Contents of the invention [0003] (1) Purpose of the invention [0004] In order to solve the technical pro...
