This invention discloses a fertilization device for the ecological cultivation of Chinese medicinal herbs, relating to the field of agricultural planting technology. It includes a spreading bucket, multiple discharge pipes at the bottom of the spreading bucket, valves on the discharge pipes, and an electric walking track at the bottom of the spreading bucket. A feeding rack is installed inside the spreading bucket, forming a semi-cylindrical storage space to hold fertilizer. Multiple through holes are located at the center of the arc-shaped surface of the feeding rack, directly below the discharge pipes. This invention allows the dispersing rack and separating plate to move laterally within the feeding rack, dispersing the fertilizer inside and effectively preventing fertilizer compaction. This ensures the fertilizer falls onto the soil surface after conforming to the specifications of the through holes, improving the quality of fertilizer application. Simultaneously, a rotating bending rod and a stirring rod can rotate along a path perpendicular to the lateral movement path of the dispersing rack, further agitating the fertilizer and improving the uniformity of fertilization.

This utility model relates to the field of seed sowing technology and discloses a special rice seed sowing device for drones. It includes a drone body, a mounting plate fixedly connected to the right end of the drone body, a storage component at the right end of the mounting plate, an adjustment component at the bottom of the storage component, and a storage box with a sliding groove on its inner wall. An extension frame is slidably connected to the inner wall of the sliding groove, and a handle is fixedly connected to the top of the extension frame. Specifically, by setting up the storage component, when the capacity of the storage box needs to be adjusted, the locking bolt is first loosened, then the handle is pulled to move the extension frame upwards. After adjusting to the appropriate position, the locking bolt is threaded into the threaded hole to lock the position of the extension frame, thereby increasing the storage capacity of the storage box, reducing the need for the drone body to fly back to add seeds, and improving sowing efficiency.
