The autonomous navigation pesticide spraying robot for the orchard operation and the working method of the autonomous navigation pesticide spraying robot can significantly reduce the labor amount and labor intensity of orchard pesticide spraying operation, and are of great significance to the improvement of quality and synergy of the modern fruit industry and the conversionof new and old kinetic energy.

The present invention relates to the field of UAV plant protection, and discloses a polygonal plot segmentation method, device, storage medium and electronic equipment, by obtaining the set UAV initial spraying heading, spraying width, plot boundary vertices and obstacles The position of the boundary vertex, the latitude and longitude coordinates are converted into plane coordinates, and the x-axis and y-axis directions are determined according to the initial spraying course, the position of the boundary point of the plot and the position of the initial spraying point; the scanning direction is divided according to the plot Sorting the plot boundary vertices and obstacle boundary vertices; performing plot segmentation scanning on the sorted plot boundary vertices and obstacle boundary vertices to divide the operation plot into multiple sub-regions and generate a sub-region adjacency graph; According to the spraying heading of the UAV, the plane coordinates will be reversely rotated to obtain and store the boundary information of the divided sub-regions. The present invention can divide any polygonal plot containing arbitrary polygonal obstacles into several simple polygonal plots, so that the covering and spraying operation of each segmented plot can be realized by using the existing planning method, and then the arbitrary polygonal plot can be realized spraying operations.

The invention discloses an agricultural unmanned aerial vehicle self-regulating spraying frame, which includes an unmanned aerial vehicle body, a water tank and a rotor arranged on the unmanned aerial vehicle body, and at least one horizontally arranged horizontal pipe is fixedly connected to the bottom end of the unmanned aerial vehicle body , the horizontal pipe communicates with the water tank through a connecting pipe, and a valve is installed on the connecting pipe; a female sleeve is vertically arranged at the lower end of the rotor, and the female sleeve adopts a hollow structure. The invention takes the traditional fixed spraying frame as the active one, so that it can dynamically adjust and spray low-altitude trees and ultra-low-altitude vegetation under the action of wind force. Fog droplets penetrate deep into the leaf layer according to gravity or along the wind; when spraying relatively low vegetation close to the ground, multiple nozzles are approximately at the same level, so as to maximize the spraying range. And this adjustment does not require electricity, which indirectly improves the battery life of agricultural drones, energy saving and environmental protection.

The invention discloses a full-chain cold-state preparation method of an asphalt-based coating material, belonging to the field of road engineering tests. The coating material is prepared from a specific ratio of main solvent 1, asphalt binder, functional filler, modified masterbatch, stabilizer, and drier. The Brookfield viscosity of the coating material at 20°C is 2000 ‑4000cPs, the whole process of coating material preparation is carried out under cold state or normal temperature conditions. Compared with the prior art, the implementation method of the present invention overcomes the requirement that the asphalt binder needs to be heated and transported during the traditional process, and the whole production chain It realizes cold crushing and normal temperature mixing, ensures the uniformity and stability of stirring, improves production safety, reduces production energy consumption, and has good popularization and application value.

The invention provides a garden irrigation device. A small trolley frame is provided with a retractable cylinder and a lifting cylinder, the retractable cylinder pushes a pesticide spraying tube to stretch and retract, the lifting cylinder drives the retractable cylinder and a pesticide spraying tube support mounted at the front end of the retractable cylinder to lift and fall, thus, pesticide spraying operation is realized, the far end of the pesticide spraying tube is overturned upwards by a lifting push plate on an extending support which is horizontally arranged at the front end of the trolley frame, and a pesticide spraying height adjusting function is fulfilled. The garden irrigation device is simple in structure and convenient to use, and can be widely applied to various gardens.
