Description

Technical Field

[0001] This invention belongs to the field of unmanned aerial vehicle (UAV) technology, specifically relating to a pollination device for agricultural UAVs. 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, or operated autonomously, either completely or intermittently, by an onboard computer. Currently, my country's intelligent manufacturing industry is developing rapidly, with various intelligent new products emerging in an endless stream, and UAV technology is one of them. According to statistics from industry development associations, agricultural drones account for more than 40% of UAV applications.

[0003] In fruit tree cultivation, pollination is necessary to improve fruit quality and yield, promoting pollen transfer and fertilization. However, many cross-pollinated crops cannot self-pollinate or have low fruit set rates, requiring artificial cross-pollination. Given the large number of fruit trees planted, artificial pollination necessitates the use of pollinators to spray pollen onto female flowers, which is time-consuming, labor-intensive, and may delay optimal pollination. Therefore, using agricultural drones for pollination is a better solution.

[0004] Existing drone pollination devices often suffer from pollen clumping due to the compression of pollen grains during storage, hindering effective pollen fragmentation and reducing pollen viability during operation, thus lowering pollination efficiency. Furthermore, when these clumped pollen grains are sprayed through the spraying device, they adhere to the nozzle or spray nozzle, leading to uneven and discontinuous pollen distribution. This can negatively impact plant fertilization and fruit set. Utility Model Content

[0005] The purpose of this invention is to provide a pollination device for agricultural drones that can stir pollen to prevent it from clumping together and ensure that the pollen is finely processed. Simultaneously, it can filter and absorb the stirred pollen, removing impurities to prevent clogging during spraying.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A pollination device for agricultural drones includes a drone body, with a pollination mechanism located at the bottom of the drone body.

[0008] The pollination mechanism includes a mounting box located at the bottom of the drone body, a storage slot is provided inside the mounting box, a pollination box is slidably arranged in the storage slot, and a stirring device is provided inside the pollination box;

[0009] The stirring device includes a stirring motor, the output end of which is connected to a spiral blade and a stirrer via a transmission assembly. The transmission assembly includes a drive gear fixedly mounted on the output end of the stirring motor, the drive gear being connected to a driven gear via a transmission chain, and the driven gear being fixedly connected to the stirrer via a transmission rod. This device is used to stir and agitate the pollen to prevent it from clumping.

[0010] An aspiration assembly, comprising an aspirator slidably disposed within the storage slot, wherein the aspirator is located above the pollination box;

[0011] The pollen is placed in the pollination box and stirred by the stirring device. Then, the suction component is controlled to work to suction the pollen. Finally, the pollen is sprayed through the pollination nozzle.

[0012] Furthermore, a stirring rod is fixedly connected to the output end of the stirring motor, the stirring rod is rotatably connected to the pollination box, and the spiral blade is fixedly disposed on the outside of the stirring rod.

[0013] Furthermore, a motor plug is fixedly provided on one side of the stirring motor, and the motor plug is slidably connected to the connection port opened in the storage tank.

[0014] Furthermore, the suction assembly also includes an electric push rod fixedly disposed above the storage slot, and the suction device is fixedly disposed at the output end of the electric push rod.

[0015] Furthermore, the absorber is connected to the pollination nozzle via a transmission pipe, and the absorber is equipped with an aspiration pump to generate negative pressure, thereby absorbing the pollen and transferring it to the nozzle.

[0016] Furthermore, a control connector is fixedly provided on the pollination box. When the control interface opened in the storage slot of the control connector is slidably connected, the electric push rod is energized.

[0017] The technical effects achieved by this utility model are as follows:

[0018] This invention relates to a pollination device for agricultural drones. By incorporating a stirring device, the pollen in the pollination box is stirred and turned, resulting in finely broken-down pollen. This ensures that the pollen transferred to the nozzle does not stick together, allowing it to be evenly sprayed onto the crop through the nozzle, achieving precise and efficient aerial pollination and improving the pollination success rate.

[0019] This invention relates to a pollination device for agricultural drones. By setting up an adsorption device, it can effectively control the absorption of pollen, ensuring precise control of the amount of pollen sprayed, so that plants can receive a sufficient amount of pollen, ensuring accurate pollination. At the same time, the adsorption device can effectively filter out residual impurities in the pollen, ensuring that the amount of pollen sprayed is uniform and continuous.

Detailed Implementation

[0026] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0027] like Figures 1-4 As shown, a pollination device based on an agricultural drone includes a drone body 10, and a pollination mechanism 20 is provided at the bottom of the drone body 10.

[0028] The pollination mechanism 20 includes a mounting box 21 located at the bottom of the drone body 10. A storage slot 22 is provided inside the mounting box 21. A pollination box 23 is slidably arranged inside the storage slot 22. A stirring device 30 is provided inside the pollination box 23.

[0029] The stirring device 30 includes a stirring motor 31, the output end of which is connected to a spiral blade 32, and a stirrer 34 is connected to it via a transmission assembly 33. The transmission assembly 33 includes a drive gear 331 fixedly mounted on the output end of the stirring motor 31. The drive gear 331 is connected to a driven gear 333 via a transmission chain 332. The driven gear 333 is fixedly connected to the stirrer 34 via a transmission rod. The device is used to stir and agitate the pollen to prevent it from clumping.

[0030] The suction assembly 40 includes a suction device 41 that is slidably disposed in the storage slot 22 and is located above the pollination box 23.

[0031] In this process, pollen is placed in pollination box 23, stirred by stirring device 30, and then the suction component 40 is controlled to work to suction the pollen. Finally, the pollen is sprayed through pollination nozzle.

[0032] It should be noted that a camera is installed at the bottom of the drone to observe the area to be pollinated, ensuring accurate pollination of the plants. Simultaneously, an intake port is located at the bottom of the extractor 41, and a filter screen is installed at the intake port to effectively filter the refined pollen, ensuring that no impurities enter the transmission tube and clog the nozzle during pollination, thereby improving pollination efficiency. Furthermore, a handle is provided on the pollination box 23 for easy placement and removal.

[0033] In this embodiment, the drone body 10 serves as the carrier of the pollination device, responsible for transporting the pollination mechanism 20 to the designated crop area. The pollination mechanism 20 is used to perform pollination, including a mounting box 21 located at the bottom of the drone body 10 for fixing and protecting the components inside the pollination mechanism 20. A storage slot 22 is provided in the mounting box 21 to accommodate and position the pollination box 23, allowing the pollination box 23 to slide inside while preventing the external environment from affecting the pollination process. A stirring device 30 is used to mix and disperse pollen. By placing it inside the pollination box 23, it ensures that there is no sticky or clumped pollen during the pollination operation, which would lead to uneven pollination. The stirring device 30 includes a stirring motor 31 that provides power for the stirring process, with a spiral blade 32 and a transmission assembly 33 at its output end. The spiral blades 32 are mounted on the output end of the stirring motor 31 via the stirring rod 311. Through rotation, they generate a vortex effect, thoroughly agitating the pollen stored in the pollination box 23, effectively preventing pollen accumulation and improving pollination efficiency. Specifically, the drive gear 331 in the transmission assembly 33 is fixed to the output end of the stirring motor 31. The efficient operation of the stirring motor 31 enables its rotation. Since the drive gear 331 is connected to the driven gears 333 via the transmission chain 332, it effectively drives the driven gears 333 on both sides to rotate synchronously. A transmission rod is fixedly mounted on the driven gears 333, and a stirrer 34 is fixedly mounted above the transmission rod, causing the stirrer 34 to rotate within the pollination box 23 and agitate the pollen. The spiral blades 32 and the stirrer 34 ensure that the pollen is evenly distributed within the pollination box 23, preventing pollen clumping and increasing the pollination probability. The suction assembly 40 is used to absorb the stirred pollen, ensuring it can be transferred to the pollination nozzle for spraying. By placing the suction device 41 inside the storage tank 22 and above the pollination box 23, and through the action of the electric push rod 42, the suction device 41 can be slidably connected to the pollination box 23, forming a sealed space. Through the operation of the suction device 41, pollen can be drawn from the pollination box 23 and evenly sprayed onto the crop through the nozzle at the bottom of the mounting box 21, achieving precise and efficient aerial pollination. This ensures that pollen is efficiently and evenly distributed on the crop surface, ensuring that each flower fully contacts the pollen, thus improving the pollination success rate.

[0034] like Figure 3 , Figure 4As shown, the stirring rod 311 is fixedly connected to the output end of the stirring motor 31 and rotatably connected to the pollination box 23. This ensures that the stirring rod 311 can effectively drive the spiral blades 32 located on its outer side to rotate. The power transmission through the stirring rod 311 enables the spiral blades 32 to generate a vortex effect, preventing pollen deposition and clumping, ensuring uniform pollen distribution, and improving pollination efficiency. A motor plug 312 is fixedly provided on one side of the stirring motor 31 and is electrically connected to the stirring motor 31. Through a sliding connection with the connection port opened in the storage tank 22, the stirring motor 31 can be effectively powered and controlled, thereby effectively controlling the stirring time and ensuring flexibility and stability during operation.

[0035] like Figure 2 , Figure 3 As shown, by fixing the electric push rod 42 above the storage tank 22 and fixing the extractor 41 at its output end, the electric push rod 42 provides power to drive the extractor 41 to move up and down, thereby controlling the position of the extractor 41 within the storage tank 22. This allows the extractor 41 to slide above the pollination box 23, forming a relatively stable sealed space, thus facilitating pollen extraction. An extraction pump is installed inside the extractor 41 to generate negative pressure for pollen extraction. A transmission pipe is installed at the output end of the extraction pump to ensure that pollen does not leak or clog during transport, ensuring the continuity and stability of pollination. The pollination nozzle is fixed at the other end of the transmission line to effectively output the extracted pollen. It should be noted that a control connector 231 is fixedly installed on the pollination box 23. The control connector 231 is the wiring connector for the electric push rod 42. When the control connector 231 is slidably connected to the control interface opened in the storage slot 22, the electric push rod 42 is energized, which can effectively control the electric push rod 42 to move the absorber 41, ensuring the safety of the absorption assembly 40 during use. When pollination is not required, the electric push rod 42 can be controlled to separate the absorber 41 from the pollination box 23, and the pollination box 23 can be disassembled, facilitating the user's control and management of the absorption assembly 40.

[0036] The working principle of this utility model is as follows: Pollen is placed in the pollination box 23, which is then slidably connected to the storage tank 22. The pollination box 23 is then moved within the storage tank 22, connecting the control connector 231 on the pollination box 23 to the control interface in the storage tank 22. This enables the electric push rod 42 to conduct electricity and control, thereby driving the absorber 41 to slide above the pollination box 23, forming a sealed space. At this time, the stirring motor 31 located below the pollination box 23 connects to the connection port in the storage tank 22 via the motor plug 312, energizing and controlling the stirring motor 31. The stirring motor 31 can then be started, driving the transmission assembly 33 and the stirring rod 311 to rotate. This, in turn, drives the spiral blades 32 located on the outside of the stirring rod 311 and the stirrer 34 fixed above the transmission rod to work, thus stirring and agitating the pollen within the pollination box 23. Then, the absorber 41 can be activated to absorb the pollen in the pollination box 23 and transfer it to the pollination nozzle through the transmission tube, so that the pollination nozzle can spray the pollen evenly onto the crop and improve the pollination success rate.

[0037] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
