[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This invention involves horizontally mounting the main support rod onto the seeder, securing the mounting block with bolts, and then pushing multiple movable side boxes to allow the side locking blocks to move horizontally along the side locking grooves, creating a specified spacing between the side boxes. Rotating the top locking screw secures the side locking blocks within the side locking grooves. Selecting a matching box for the appropriate seed size, the box is secured to the mounting hole using the side mounting blocks. Simultaneously, one end of the side polygonal locking shaft is inserted into the polygonal hole at one end of the rotating block. Finally, the top sealing cover is flipped open, and seeds are fed into the storage box. The internal storage operation involves connecting the seeds via a telescopic tube at the bottom, allowing them to fall downwards into the through-hole at the top. Vibration from the side vibrator ensures the seeds fall without clogging. After the seeds fall into the corresponding seed-holding troughs, a rotating motor on the side drives a rotating block to rotate the inner turntable, causing the seed-holding troughs to flip downwards and align with the through-holes below. Finally, the seeds are discharged outwards through the discharge pipe at the bottom, fulfilling the sowing requirement. The modular structure allows for assembly and use as needed, and the adjustable spacing and capacity enable more precise sowing. Attached Figure Description

[0022] Please see Figure 2-5In this embodiment of the present invention, a precision seeding device for a seeder is provided, wherein an inner turntable 13 is snapped onto the inner side of the docking box 6, and material-holding channels 14 are evenly distributed on the outer side of the inner turntable 13. A polygonal clamping shaft 15 is inserted into one side of the docking box 6. A telescopic connecting pipe 12 is configured with a telescopic pipe structure, and the top end of the telescopic connecting pipe 12 is fixedly connected to the center through hole on the bottom surface of the storage box 9, while the bottom end is fixedly inserted into the through hole 17 on the top surface of the docking box 6. The outer side wall of the inner turntable 13 is tightly connected to the inner side wall of the docking box 6. There are multiple material-holding channels 14, which are arranged in a ring at equal intervals on the outer side of the inner turntable 13.

Then, multiple movable side boxes 5 are pushed, causing the side locking blocks 21 to move horizontally along the side locking grooves 2, creating a specified spacing between the movable side boxes 5. The locking screw 22 on the top surface is rotated to fix the side locking blocks 21 inside the side locking grooves 2. After selecting the appropriate connecting box 6 for the seed size, the connecting box 6 is locked into the mounting hole 19 using the side mounting blocks 16. Simultaneously, one end of the side polygonal locking shaft 15 is inserted into the polygonal hole at one end of the rotating block 18. After the top sealing cover 10 is flipped open, seeds are placed into the storage box 9. The seeds fall downwards into the through hole 17 at the top through the telescopic connecting pipe 12 at the bottom. The vibration of the vibrator 11 on the side prevents the seeds from falling and causing blockage. After the seeds fall into the corresponding material trough 14, the rotation of the rotating motor 20 on the side causes the rotating block 18 to drive the inner turntable 13 to rotate. The material trough 14 containing the corresponding amount of seeds flips downwards and connects with the through hole 17 at the bottom. Finally, the seeds are discharged outwards through the discharge pipe 7 at the bottom to meet the sowing requirements.
