Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a UAV equipped with an agricultural and forestry spraying device. Background Technology

[0002] With the modernization of agriculture, traditional manual agricultural labor is gradually being replaced by agricultural drones. For example, when spraying pesticides and fertilizers, agricultural drones can be remotely controlled to ensure that the pesticides are evenly sprayed onto crops, avoiding the harm to manual labor and improving work efficiency. Traditional agricultural drones are equipped with a storage tank at the bottom to store the pesticides, and a nozzle at the bottom of the tank to spray the pesticides. The pesticides in the storage tank are pressurized by a booster pump and sprayed out of the nozzle. However, due to the limited carrying capacity of the drone, the volume of the storage tank cannot be made too large, which limits the spraying range of the pesticides. This also results in a long travel path for the drone. Therefore, it is necessary to design a spraying device that can both increase the spraying range and maintain structural balance. Utility Model Content

[0003] To overcome the shortcomings of the prior art, the technical solution adopted by this utility model is as follows: a drone with an agricultural and forestry spraying device, including a drone body and a fixed frame set inside the drone body, and also including a liquid storage tank, a booster pump, a spray pipe, nozzles, a fixing rod and a clamp. The liquid storage tank is detachably connected to the bottom of the fixing frame. The top of the liquid storage tank is provided with a booster pump and a liquid inlet pipe. The bottom of the liquid storage tank is connected to a spray pipe extending to one side of the drone body. The bottom of the spray pipe is provided with nozzles distributed at intervals. The drone body and the spray pipe are connected by a fixing rod distributed in a triangular pattern. One end of the fixing rod is detachably connected to the fixing frame, and the other end is detachably connected to the spray pipe through a clamp.

[0004] Using the above technical solution, the liquid storage tank is a hollow, sealed tank used to store liquids such as pesticides and liquid fertilizers. The air pressure inside the liquid storage tank is increased by a booster pump, and together with the drone body, it meets the needs of high-altitude spraying. The liquid storage tank is connected to spray pipes extending to both sides, which increases the spraying range and reduces the travel of the drone body. The spray pipes are fixed by a fixed rod in a stable triangular structure to prevent the spray pipes from bending. The spray pipes are symmetrically distributed on both sides of the drone body to maintain the balance of the drone body during flight.

[0005] The present invention is further configured such that the fixing frame includes a vertical rod and a horizontal rod, the two ends of the horizontal rod are provided with screws for connecting the fixing rod, and the bottom of the vertical rod is provided with a mounting part for connecting the liquid storage tank.

[0006] Furthermore, the liquid storage tank is provided with connecting blocks distributed in a circular pattern, and the mounting part is provided with a slot and a connecting hole. The connecting block is snapped into the slot and connected to the fixing frame by bolts through the connecting hole.

[0007] Furthermore, the two ends of the fixing rod are respectively provided with a first connecting ring and a second connecting ring, the clamp is provided with mounting holes coaxially distributed with the first connecting ring, and the screw is provided with threaded holes corresponding to the second connecting ring.

[0008] Using the above technical solution, the mounting frame is composed of vertical and horizontal bars connected by welding or sleeves to form a rectangular skeleton structure. The bottom of the vertical bar is milled with a slot for installing the liquid storage tank, and the two ends of the horizontal bar are detachably connected with screws for installing the mounting rods. This ensures that during the flight of the UAV, the resistance experienced by the liquid storage tank, spray pipe, and mounting rods is transferred to the mounting frame, maintaining the stability of the structure.

[0009] The present invention is further configured such that two sets of fixing rods are symmetrically distributed on both sides of the mounting hole of the clamp, and the two sets of fixing rods form a triangular structure by the fixing combination of screw and clamp.

[0010] Using the above technical solution, two sets of semi-circular clamps are combined and fitted onto the spray pipe. The first connecting ring and the second connecting ring are welded to both ends of the fixing rod. The first connecting ring and the clamps share the same set of bolts for fixing. The second connecting ring is connected to the end face of the screw rod by screw threads. The overall structure design is reasonable.

[0011] The present invention is further configured such that the liquid storage tank is threadedly connected to a nozzle via a flange, the spray pipe is provided with a sleeve rotatably connected to the nozzle, the nozzle is provided with a stepped surface that restricts the sleeve, and a side hole that communicates with the spray pipe.

[0012] Furthermore, the nozzle has sealing grooves on the upper and lower sides of the side hole for installing sealing rings, and the sleeve is sealed to the nozzle through the sealing grooves.

[0013] By adopting the above technical solution, when installing the spray pipe, the spray pipe is movably connected to the liquid storage tank, which compensates for the installation error of the fixing rod, so that the spray pipe will not bend and generate stress, thus maintaining the stability of the spray pipe structure.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The storage tank is connected to spray pipes extending to both sides, which increases the spraying range and reduces the flight distance of the drone.

[0016] 2. The spray pipe is fixed by a fixing rod in a stable triangular structure to prevent the spray pipe from bending during flight, thereby improving the stability of the spraying device structure and maintaining the balance of the aircraft.
