A self-carrying liquid type vegetation layer material spraying unmanned aerial vehicle and a construction method thereof

Abstract

The application discloses a self-carrying liquid type vegetation layer material spraying and seeding unmanned plane and a construction method thereof. The spraying and seeding unmanned plane comprises an unmanned plane flight platform, a machine-mounted hopper installed in the belly area of the unmanned plane flight platform, a conveying assembly communicated with the machine-mounted hopper, a driving motor for driving the conveying assembly, a universal pump spraying assembly communicated with the conveying assembly through a transition feeding cavity, and a stretching arm assembly connected with the universal pump spraying assembly. The two-stage feeding system and the pneumatic pressurized spraying device are carried by the unmanned plane flight platform, so that the ecological restoration problem of a poor accessibility area of a high and steep slope surface is solved. The stable feeding of the conveying assembly and the pressurization of the volumetric pumping cavity are adopted, so that the stable conveying of high viscosity material is realized. The spraying energy in the super high viscosity working condition is compensated by the low angle pneumatic boost of the air jet spraying ring, the spraying nozzle material is inhibited, and finally the long-distance, directional and uniform spraying and seeding in the complex slope surface working condition is realized, and the operation safety and the material utilization rate of the ecological restoration are significantly improved.
