The double-groove pulley 13 can simultaneously use the first belt 15 and the second belt 18 to drive the first pulley 14 and the second pulley 17 to rotate respectively. The rotation of the first pulley 14 drives the stirring shaft 21 to rotate. This action drives the multiple stirring blades 22 thereon to rotate, stirring the pelletized pepper seeds. At the same time, the screening net 32 screens the seeds that are oversized and retains them on it, while the pelletized pepper seeds that meet the size requirements pass through the screening net 32. The seeds that meet the size requirements after screening enter the conical guide barrel 3, and then are introduced into the upper discharge barrel 4, and then enter the sowing barrel 5 (a barrel with alternating curved surfaces and flat surfaces). at the same time, the rotation of the second pulley 17 drives the rotating rod 16 to rotate, and this action drives the multiple first bevel gears 19 installed thereon. The first bevel gear 19 engages with the second bevel gear 20, prompting the second bevel gear 20 to also rotate, thereby synchronously driving the first rotating shaft 8 connected to the second bevel gear 20 to rotate. Driven by the first rotating shaft 8, the working disk 9 rotates, and the grooves 10 on the working disk 9 cooperate with the pelletized pepper seeds and are transmitted to the lower discharge barrel 6. Finally, they are sown into the field through the sowing nozzle 7. It is worth mentioning that the device realizes the synchronous rotation of the stirring mechanism and the multiple first rotating shafts 8 through the driving mechanism, which not only saves energy consumption, but also improves the overall efficiency of the sowing operation. In addition, during the sowing process of the pelletized pepper seeds, the device can screen and separate the pelletized pepper seeds that are too large in size, avoiding the problem of clogging caused by the seeds being too large and getting stuck in the grooves 10 of the working disk 9, thereby improving the sowing efficiency and uniformity of the pelletized pepper seeds.
