[0003] When traditional forestry drones operate in complex forest environments, their ultra-low-altitude flight is often restricted by trees, and fixed spraying devices have a small coverage area and uneven spraying, which affects the efficiency of plant protection. Therefore, there is an urgent need for a vector drone for forestry. Utility Model Content

[0006] The spraying mechanism includes a liquid storage tank, a pump body installed at the bottom of the liquid storage tank, a pump body with a fixed connection to a pump pipe at the pump's pumping end, a pump body with a fixed connection to an outlet pipe at the pump's outlet end, and branch pipes fixedly connected to both ends of the outlet pipe. Spray pipes are installed at the ends of the branch pipes away from the outlet pipes via rotary joints. Multiple nozzles are fixedly connected to the outer side of each spray pipe.

[0007] Preferably, the end of the pumping pipe away from the pump body is fixedly connected to the liquid storage tank, and the liquid storage tank is provided with an injection pipe.
[0008] The drone, which uses vector flight, can rotate its propellers to adjust its flight attitude to pass through forests, avoid being blocked by trees, and avoid the possibility of operating at extremely low altitudes (below 5 meters) in forestry fields due to tree obstruction.
[0009] Preferably, the two spray pipes are rotatably mounted inside the limiting ring, and the front of the liquid storage tank is provided with a transparent observation window.

The pump body draws liquid through the water extraction pipe and delivers it to the distribution pipe through the water outlet pipe. The distribution pipe distributes the liquid to the spray pipes on both sides, and the liquid is sprayed out by multiple nozzles on the spray pipes to achieve synchronous spraying on both sides. The spray pipes are connected to the distribution pipes through a rotary joint, which enables the spray pipes to rotate. The second synchronous pulley is driven by a servo motor, and the two first synchronous pulleys are driven by a synchronous belt to make the spray pipes rotate back and forth.

[0013] Preferably, the top of each spring is fixedly connected to the support leg, and the bottom of each base sleeve is fixedly connected to a buffer base plate.
[0014] The support legs and the base sleeve adopt a sliding sleeve design. When landing, the support legs compress the springs, which provide primary cushioning. The cushioning base plate is made of rubber and provides secondary shock absorption.
[0015] Preferably, the four support legs are arranged in pairs, and each pair of support legs is respectively located at both ends of the liquid storage tank.
[0016] Compared with the prior art, the beneficial effects achieved by this utility model are:
[0017] First, this utility model uses a servo motor to drive the spray pipe to rotate back and forth, and with the fan-shaped spray surface design, the coverage area of a single flight is greatly increased, the number of repeated flights is significantly reduced, and the plant protection efficiency is improved.
[0018] Secondly, the support mechanism of this utility model adopts a primary spring buffer and a secondary rubber buffer base plate for shock absorption, which absorbs the landing impact force, avoids damage to the medicine box and precision parts, and extends the service life of the equipment.

[0030] Two spray pipes 15 are respectively rotatably installed inside the limiting ring 18, and a transparent observation window is provided on the front of the liquid storage tank 11.
[0031] The top of the liquid storage tank 11 is fixedly connected to the main body 1 of the drone, and the two first synchronous pulleys 19 and one second synchronous pulley 21 are connected by a synchronous belt 22.

The liquid storage tank 11 is replenished with liquid through the injection pipe, and the pump body 12 draws liquid through the water extraction pipe 13 and delivers it to the distribution pipe 14 through the water outlet pipe.

Multiple nozzles 16 are evenly distributed on the surface of the spray pipe 15, forming a fan-shaped spray surface during rotation to expand the coverage area. The support rod 17 and the limiting ring 18 form a rotation guide structure to ensure the smooth rotation of the spray pipe 15.
