A seed metering box 4 is fixedly installed inside the device housing 1. A feed port 5 is installed on the side wall of one side of the seed metering box 4, and the feed port 5 is connected to the feed pipe 2. A driving motor 17 is installed on the side wall of the other side of the seed metering box 4. The driving motor 17 plays a role of power driving. The output end of the driving motor 17 is installed with a transmission shaft 19. A transmission gear 18 is sleeved on the surface of the transmission shaft 19. An articulated shaft 15 is movably installed inside the seed metering box 4 on one side of the transmission shaft 19. A discharge gear 23 is sleeved on the surface of the articulated shaft 15, and the discharge gear 23 meshes with the transmission gear 18. A pin shaft 21 is movably installed inside the seed metering box 4 on one side of the articulated shaft 15. A driven gear 22 is sleeved on the surface of the pin shaft 21, and the discharge gear 23 meshes with the driven gear 22.

An internal discharge port 16 is installed at the bottom end of the seed metering box 4;

[0025] First, install this structure on the drone, connect the feed pipe 2 to the material bucket, connect the circuit of this structure to the drone, and connect this structure to the controller of the drone. When it is necessary to seed and sow the seeds, the seeds enter the inside of the seed metering box 4 from the material bucket through the feed pipe 2 and the feed inlet 5. Then, turn on the drive motor 17. The drive motor 17 drives the transmission shaft 19 to rotate, and the transmission shaft 19 drives the transmission gear 18 to rotate. Under the mutual meshing of the transmission gear 18 and the spring 13, the transmission gear 18 drives the discharge gear 23 and the discharge roller 8 to rotate around the hinge shaft 15. Under the mutual meshing of the discharge gear 23 and the driven gear 22, the discharge gear 23 drives the driven gear 22 to rotate around the pin shaft 21. Under the mutual meshing of the driven gear 22 and the extrusion gear 20, the driven gear 22 drives the extrusion gear 20 and the extrusion roller 9 to rotate around the movable shaft 11. The discharge roller 8 drives the discharge holes 7 to rotate. The seeds fall into the inside of the discharge holes 7 and rotate together with the discharge holes 7. Under the transmission of multiple gears, the rotation directions of the discharge roller 8 and the extrusion roller 9 are opposite. Therefore, under the sliding fit of the extrusion roller 9 and the discharge roller 8, the extrusion roller 9 blocks the seeds overflowing from the discharge holes 7 to prevent them from falling. At the same time, the strip-shaped scraper 10 scrapes the surface of the extrusion roller 9 to prevent the seeds adhered to the surface of the extrusion roller 9 from falling through the gaps. Under the elastic support of the spring 13, the spring 13 drives the arc-shaped scraper 14 to closely adhere to the surfaces of the discharge roller 8 and the extrusion roller 9 to scrape the seeds on the surfaces of the discharge roller 8 and the extrusion roller 9 for the second time, further preventing the seeds from falling through the gaps. The discharge holes 7 drive the seeds to continuously rotate in sequence. When passing through the arc-shaped scraper 14, the seeds fall under the action of gravity and are discharged through the inner discharge port 16 and the outer discharge port 3 to complete the seed metering and sowing operation of the seeds, realizing convenient multi-structure linkage type seed metering and sowing, facilitating the scraping of the adhered seeds, and improving the accuracy of seed metering;

[0028] A servo motor 24 is installed on the inner wall of the equipment housing 1. The servo motor 24 plays a role in power driving, and a dialing gear 25 is installed at the output end of the servo motor 24;

[0029] A movable ring 27 is movably installed on the outer wall of the seed metering box 4. A toothed ring 26 is installed on the side wall of the movable ring 27, and the toothed ring 26 meshes with the feeding gear 25. A plurality of groups of feeding claws 6 are installed at equal intervals on the side wall of the movable ring 27 on one side of the toothed ring 26, and the feeding claws 6 are slidably connected to the inner wall of the equipment housing 1;

[0030] If the seeds fall into the interior of the equipment housing 1 after passing through the inner discharge port 16 and do not discharge from the outer discharge port 3, the servo motor 24 is turned on. The servo motor 24 drives the feeding gear 25 to rotate. Under the mutual meshing of the toothed ring 26 and the feeding gear 25, the feeding gear 25 drives the toothed ring 26 to rotate. The toothed ring 26 drives the movable ring 27 to rotate on the outer wall of the seed metering box 4. The movable ring 27 drives a plurality of groups of feeding claws 6 to rotate. Under the sliding fit of the feeding claws 6 and the equipment housing 1, the feeding claws 6 dial out the seeds that have fallen into the interior of the equipment housing 1 from the outer discharge port 3, so as to prevent material accumulation inside the equipment housing 1, realizing convenient scraping and sweeping of the fallen seeds, preventing material accumulation inside the device, reducing the occurrence of seed empty sowing, and improving the convenience of use.

[0031] Working principle: First, install this structure on the drone, connect the feed pipe 2 to the material bucket, connect the circuit of this structure to the drone, and connect this structure to the controller of the drone. When it is necessary to seed and sow the seeds, the seeds enter the inside of the seed metering box 4 from the material bucket through the feed pipe 2 and the feed port 5. The drive motor 17 drives the transmission shaft 19 to rotate, the transmission shaft 19 drives the transmission gear 18 to rotate, the transmission gear 18 drives the discharge gear 23 and the discharge roller 8 to rotate around the hinge shaft 15, the discharge gear 23 drives the driven gear 22 to rotate around the pin shaft 21, the driven gear 22 drives the extrusion gear 20 and the extrusion roller 9 to rotate around the movable shaft 11, the discharge roller 8 drives the discharge holes 7 to rotate, the seeds fall into the discharge holes 7 and rotate together with the discharge holes 7. The rotation directions of the discharge roller 8 and the extrusion roller 9 are opposite. Therefore, under the sliding fit of the extrusion roller 9 and the discharge roller 8, the extrusion roller 9 blocks the seeds overflowing from the discharge holes 7 to prevent them from falling. At the same time, the strip-shaped scraper 10 scrapes the surface of the extrusion roller 9 to prevent seeds from adhering to the surface of the extrusion roller 9 and falling from the gap. Under the elastic support of the spring 13, the spring 13 drives the arc-shaped scraper 14 to closely adhere to the surfaces of the discharge roller 8 and the extrusion roller 9 to scrape the seeds on the surfaces of the discharge roller 8 and the extrusion roller 9 for the second time, further preventing the seeds from falling from the gap. The discharge holes 7 drive the seeds to continuously rotate in sequence. When passing through the arc-shaped scraper 14, the seeds fall under the action of gravity and are discharged through the inner discharge port 16 and the outer discharge port 3 to complete the seed metering and sowing operation of the seeds. If the seeds fall into the equipment housing 1 after passing through the inner discharge port 16 and do not discharge from the outer discharge port 3, the servo motor 24 drives the dialing gear 25 to rotate, the dialing gear 25 drives the toothed ring 26 to rotate, the toothed ring 26 drives the movable ring 27 to rotate on the outer wall of the seed metering box 4, the movable ring 27 drives multiple groups of dialing claws 6 to rotate, and the dialing claws 6 dial out the seeds that fall into the equipment housing 1 from the outer discharge port 3 to prevent material accumulation inside the equipment housing 1, thus completing the seed metering structure for drone sowing.
