Description

Technical Field

[0001] This utility model relates to the field of drone spraying technology, specifically a wind speed and direction sensing plant protection drone spraying device. Background Technology

[0002] Unmanned aerial vehicles (UAVs), also known as drones, are unmanned aircraft controlled by radio remote control equipment and their own program control devices. The term "UAV" is actually a general term for unmanned aerial vehicles, which can be technically categorized as: unmanned fixed-wing aircraft, unmanned vertical takeoff and landing aircraft, unmanned airships, unmanned helicopters, unmanned multi-rotor aircraft, and unmanned paragliders, etc. Today, UAVs are used in various fields. In agricultural spraying, unmanned multi-rotor aircraft are commonly used for plant protection spraying. Plant protection UAV spraying devices are core equipment in modern agricultural plant protection, mainly used for the prevention and control of pests and diseases in crops such as wheat, rice, and fruit trees. However, traditional drone spraying equipment typically has fixed nozzles with a fixed spray direction and no wind-adaptive adjustment function. The pesticide droplets are easily blown away by crosswinds, which can easily lead to insufficient pesticide coverage on the target crops. Utility Model Content

The vertical plate is fixedly connected to the limiting plate. The ball bearings are rotatably connected to the upper and lower surfaces of the limiting plate, and two sets of ball bearings are provided on each of the upper and lower surfaces of the limiting plate. The rotary joint is rotatably connected between the two sets of vertical plates.

[0009] Furthermore, the upper end of the medicine box is provided with a feeding port, and a sealing cap is threaded onto the feeding port.

[0018] The mounting mechanism 9 includes a fixing ring 91, a rotating assembly 92, a rotary joint 93, a nozzle 94, and a stepper motor 95. The fixing ring 91 is fixedly connected to the bottom of the mounting plate 4. The rotating assembly 92 is located inside the fixing ring 91, and there are two sets of rotating assemblies 92. The rotary joint 93 is located between the two sets of rotating assemblies 92. The bottom end of the hose 10 is rotatably connected to the rotary joint 93. The nozzle 94 is fixedly connected to the bottom of the rotary joint 93. The stepper motor 95 is located to the right of the rotating assembly 92 on the right side.

[0019] The inner wall of the fixing ring 91 is provided with a rotating groove 911, and the upper and lower sides of the inner wall of the rotating groove 911 are provided with positioning grooves 912.

[0020] The rotating assembly 92 includes a vertical plate 921, a limiting plate 922, and ball bearings 923. The limiting plate 922 is slidably connected inside the rotating groove 911. The vertical plate 921 is fixedly connected to the limiting plate 922. The ball bearings 923 are rotatably connected to the upper and lower surfaces of the limiting plate 922, and two sets of ball bearings 923 are provided on each of the upper and lower surfaces of the limiting plate 922.

[0021] The medicine box 6 is provided with a feeding port 61 at the top, and a sealing cap is threaded onto the feeding port 61.

[0022] The upper end of the mounting plate 4 has a through groove 41, through which the hose 10 passes.

[0023] The back of the mounting mechanism 9 is provided with a wind direction positioning mechanism 11. The wind direction positioning mechanism 11 includes a side plate 111, a vertical rod 112 and a wind direction arrow 113. The side plate 111 is fixedly connected to the back of the two sets of vertical plates 921, the vertical rod 112 is fixedly connected to the bottom of the side plate 111, and the wind direction arrow 113 is fixedly connected to the bottom of the vertical rod 112.

[0024] It should be noted that the wind speed sensor 71, signal receiver 72, controller 73, water pump 8 and stepper motor 95 can all be purchased on the market or customized in the factory, and the wiring connection method and control method are mature technologies in this field and have been fully disclosed, so they will not be described again in this article.

[0025] In summary, the wind speed and direction sensing agricultural drone spraying device provided by this utility model, when the side plate 111 senses wind force, the wind direction arrow 113 will be blown by the wind and point in the direction of the wind. At this time, the wind direction positioning mechanism 11 will drive the rotating component 92 to rotate along the fixed ring 91. At this time, the ball 923 rolls along the positioning groove 912. The rotation of the rotating component 92 can make the nozzle 94 rotate synchronously. The wind speed sensor 71 can detect the wind speed, and then the signal receiver 72 transmits the signal to the controller 73. The controller 73 can control the stepper motor 95 to rotate. At this time, the stepper motor 95 can drive the rotary joint 93 to rotate, so that the spraying end of the nozzle 94 is directed towards the wind. The rotation angle of the rotary joint 93 driven by the stepper motor 95 is determined by the wind speed. For example, when the wind speed is level 3 (3.4-5.4 m / s), the rotary joint rotates 15°-20° in the direction of the wind (the higher the wind speed, the larger the angle). When the wind speed is level 4 (5.5-7.9 m / s), it deflects 25°-30°. When the wind speed is level 5 (8.0-10.7 m / s), it deflects 35°-40°. At this time, the nozzle 94 can spray obliquely in the direction of the wind. The distance of the oblique spray can offset the distance of the pesticide droplets blown by the crosswind, so that the pesticide droplets can cover the target crop. Through this structure, the spray angle and spray direction of the nozzle 94 can be adjusted in real time according to the wind speed and wind direction.
