[0022] 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 embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figure 1 As shown, an agricultural drone fertilization device includes: a loading platform 2, on which a fertilization drone 1 is placed, and a storage box 3 is provided on one side of the loading platform 2; a guide rail 5 is inserted and connected to the loading platform 2 at a position below the storage box 3, a sliding frame 8 is slidably provided on the top of the guide rail 5, and a pulley of H-shape is rotatably connected to the bottom of the sliding frame 8; the storage box 3 is connected to the top of the sliding frame 8; a conduit 301 is provided on the side of the storage box 3 near the loading platform 2; a suction pump 7 is provided on the other side of the storage box 3; a suction head 6 is provided at the input end of the suction pump 7; solid fertilizer granules 4 are placed on one side of the guide rail 5; the suction head 6 extends to the solid fertilizer granules 4; the output end of the suction pump 7 is connected to the storage box 3; and a limit pedal 9 is provided at the bottom of the loading platform 2 at a position corresponding to the side of the sliding frame 8.

[0024] When fertilizing a field using a fertilizing drone 1, the loading platform 2 is first placed in a suitable position. Then, the guide rail 5 is inserted into the bottom of the loading platform 2. Next, the sliding frame 8 is placed on the guide rail 5 and coupled with the guide rail 5 through the H-shaped pulley to increase its stability. Then, the storage box 3 is placed on top of the sliding frame 8, and the solid fertilizer granules 4 are unloaded and placed aside. The fertilizer inside the solid fertilizer granules 4 is pumped into the storage box 3 through the suction head 6 and the suction pump 7. Then, the fertilizing drone 1 is placed in a suitable position above the loading platform 2. The waste inside the storage box 3 is poured into the fertilizing drone 1 through the conduit 301 to fill the fertilizing drone 1. Then, the sliding frame 8 is slid away from the drone, and the drone is controlled to perform fertilization.

[0025] The limiting pedal 9 is used to limit the fertilizer application drone 1 when it is being fed, to prevent the fertilizer from being spilled due to the rotation of the loading platform 2. When the drone returns, it will still stay above the loading platform 2. At this time, the position may be too low. The drone can be rotated to a suitable position through the loading platform 2, and then the fertilizer can be fed through the conduit 301.

[0026] The device has a simple structure and can be disassembled, making it convenient for transportation. It can also achieve fast and safe loading without requiring much manual operation.

[0027] See attached document Figure 2 A support rod 802 is fixedly connected to the bottom of the storage box 3. A roller is provided at the end of the support rod 802. A concave groove 801 is fixedly installed longitudinally on the sliding frame 8 corresponding to the position of the roller. The roller is slidably connected to the concave groove 801.

[0028] According to the above structure, the concave chute 801 and the roller are designed for longitudinal sliding of the storage box 3, and cooperate with the lateral sliding of the sliding frame 8 and the guide rail 5 to adjust the position of the outlet of the conduit 301 to adapt to the position of the fertilizer application drone 1. The H-shaped groove of the pulley is deep enough to engage deeply with the guide rail 5, so that the shape and structure of the pulley can balance the center of gravity shift caused by the longitudinal sliding of the storage box 3.

[0029] See attached document Figure 3 The loading platform 2 includes a base plate 201, a turntable 202 is rotatably mounted on the top of the base plate 201, a sealing air pressure chamber 204 is opened on the base plate 201 corresponding to the sealing cavity 903, and a friction limiting block 203 is vertically slidably mounted on the top of the sealing air pressure chamber 204; the limiting pedal 9 includes a lower support block 901, a sealing cavity is opened inside the lower support block 901, a step block is slidably mounted inside the sealing cavity, a step block 902 is slidably mounted inside the sealing cavity 903, the step block 902 is vertically slidably mounted with the sealing cavity 903, and a return spring 904 is fixedly connected between the step block 902 and the sealing cavity 903, and the return spring 904 is connected to the sealing air pressure chamber 204.

[0030] According to the above structure, when the fertilizer application drone 1 returns and stops above the loading platform 2, its position may be slightly off. At this time, the turntable 202 needs to be rotated manually to make the fertilizer application drone 1 rotate to the appropriate position for filling. During the filling process, in order to prevent the turntable 202 from rotating, the staff needs to step on the foot block 902 to make it slide downward. Since the sealing cavity 903 is a sealed design, the gas inside is compressed and flows through the sealed air pressure cavity 204 to the bottom of the friction limit block 203, causing the friction limit block 203 to move upward and contact the turntable 202. The top of the friction limit block 203 is set as a rough surface to increase the friction between it and the turntable 202.

[0031] See attached document Figure 4 A conduit 301 is fixedly connected to the side of the storage box 3 near the fertilizer drone 1. A discharge port is opened in the storage box 3 corresponding to the position of the conduit 301. A discharge gate 302 is vertically slidably arranged inside the discharge port. A drive motor 305 is fixedly installed on the top of the storage box 3 corresponding to the discharge gate 302. A screw 304 is fixedly connected to the output end of the drive motor 305. A threaded drive column 303 is fixedly connected to the outside of the discharge gate 302. The screw 304 and the threaded drive column 303 are threadedly connected.

[0032] According to the above structure, a handle is provided on one side of the storage box 3. The handle is used to slide the storage box 3 and is equipped with a motor switch. When the end of the conduit 301 is connected to the feed inlet of the fertilizer drone 1, the drive motor 305 can be controlled by pressing the switch on the handle on one side of the storage box 3 to drive the screw 304 to rotate and make the threaded drive column 303 move upward. At this time, the fertilizer inside the storage box 3 will be discharged through the discharge port into the conduit 301 and enter the fertilizer drone 1.

[0033] The working principle of this utility model is as follows: When it is necessary to fertilize the field with the fertilizer application drone 1, firstly, place the loading platform 2 in a suitable position, then insert the guide rail 5 into the bottom of the loading platform 2, then place the sliding frame 8 on the guide rail 5, then place the storage box 3 on the top of the sliding frame 8, unload the solid fertilizer granules 4 and place them aside, and then use the suction head 6 and the suction pump 7 to pump the fertilizer inside the solid fertilizer granules 4 into the storage box 3. Then, place the fertilizer application drone 1 in a suitable position above the loading platform 2, and pour the waste material inside the storage box 3 into the fertilizer application drone 1 through the conduit 301 to fill the fertilizer application drone 1. Then, slide the sliding frame 8 away from the drone, and then control the drone to apply fertilizer.

[0034] The limiting pedal 9 is used to limit the fertilizer application drone 1 when it is being fed, to prevent the fertilizer from being spilled due to the rotation of the loading platform 2. When the drone returns, it will still stay above the loading platform 2. At this time, the position may be too low. The drone can be rotated to a suitable position by the loading platform 2, and then the fertilizer can be fed through the conduit 301.

[0035] 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 principle 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.
