[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0024] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, welding, and bonding that are mature in the existing technology, and will not be described in detail here.
[0025] Depend on Figures 1 to 7As shown in the embodiment, this embodiment includes a drum 1, multiple duckbill-type seeding mechanisms, and multiple duckbill-type seeding mechanisms arranged circumferentially along the drum wall of the drum 1. Each duckbill-type seeding mechanism includes a seeding cavity 10 disposed on the outer wall of the drum 1. The inner end of the seeding cavity is provided with a seeding cavity inlet, and the outer end of the seeding cavity is provided with a seeding outlet. A seeding outlet opening and closing rotating plate 2 and a rotating plate opening and closing drive mechanism 13 are used to open or close the seeding outlet. When the rotating plate opening and closing drive mechanism 13 is in contact with the ground and is pressed, it controls the seeding outlet opening and closing rotating plate 2 to open the seeding outlet. When it leaves the ground, it controls the seeding outlet opening and closing rotating plate 2 to close the seeding outlet. The duration for which the rotating plate opening and closing drive mechanism 13 controls the seeding outlet opening and closing rotating plate 2 to open the seeding outlet is the seeding time window. It also includes multiple volute-type inoculation structures. Each volute-type inoculation structure is fixed on the inner side of the drum wall of the drum 1 and corresponds one-to-one with each duckbill-type seeding mechanism. Each volute-type inoculation structure includes an inoculation cup, an inoculation cup outlet conveying channel 9, and a volute-type seed conveying structure.
[0026] The inoculation cup includes an inoculation cup body 3, which has an inoculation cup inlet 8 and an inoculation cup outlet. The inoculation cup inlet 8 corresponds to the seed outlet 4 of the seeder, so that the seeds discharged from the seed outlet 4 of the seeder are collected by the inoculation cup body 3 through the inoculation cup inlet 8. The inoculation cup outlet is located at the bottom of the inoculation cup body 3.
[0027] The volute-type inoculation structure includes a volute-type inoculation structure seed inlet 5, a volute-type seed transport channel 6, and a volute-type inoculation structure seed outlet 7. The volute-type inoculation structure seed inlet 5 is connected to the seed outlet of the inoculation cup through the seed transport channel 9. The inner end of the volute-type seed transport channel 6 is the seed inlet end 6-1, which is located at the lower end of the volute-type inoculation structure seed inlet 5 and is used to receive the seeds that fall from the volute-type inoculation structure seed inlet 5. The outer end of the volute-type seed transport channel 6 is the seed outlet 7, which is the seed outlet end of the volute-type seed transport channel. The volute-type structure from the seed inlet end 6-1 to the seed outlet end is a volute-type structure that surrounds the volute-type inoculation structure seed inlet 5 from bottom to top and then downwards.
[0028] During sowing, when the volute-type inoculation structure rotates to its lowest point with the roller 1, it is positioned at the seed outlet 4 of the seeder. The seeds sown at the seed outlet 4 fall into the inoculation cup body 3 through the seed inlet 8. As the volute-type inoculation structure continues to rotate, it tilts upwards. The seed delivery channel 9 at the seed outlet of the inoculation cup gradually tilts downwards from the connection end of the seed outlet of the inoculation cup to the connection end of the seed inlet 5 of the volute-type inoculation structure, allowing the seeds to slide from the seed outlet of the inoculation cup into the seed inlet 5 of the volute-type inoculation structure and fall to the seed inlet end 6-1 of the volute-type seed delivery channel. As the volute-type inoculation structure continues to rotate, the seed delivery channel 6, located at its lowest point, gradually moves from the seed inlet end 6-1 to the seed outlet end of the volute-type seed delivery channel. This guides the seeds from the seed inlet 6-1 of the volute seed conveying channel to the seed outlet 6-1. When the duckbill-type sowing mechanism corresponding to the volute inoculation structure approaches the ground, the seeds fall from the seed outlet 7 of the volute inoculation structure to the seed inlet of the sowing chamber of the duckbill-type sowing mechanism under their own gravity, thus entering the sowing chamber 10. This ensures that the seeds are transported into the sowing chamber 10 in advance before the sowing port opening and closing rotating plate 2 opens, before the rotating plate opening and closing drive mechanism 13 contacts the ground. This prevents missed sowing caused by the sowing time window being too short when the sowing speed is too fast, resulting in too long a time for the seeds to be discharged from the seed outlet 4 to the inoculation cup and then directly discharged from the inoculation cup into the sowing chamber 10, which may lead to the seeds not being discharged in time during the opening period of the sowing port opening and closing rotating plate 2.
[0029] The outer walls of each inoculation cup 3 and the outer walls of each volute-type seed delivery channel 6 of the volute-type inoculation structure are respectively annular sidewall plates 11. The two annular sidewall plates 11 fix each volute-type inoculation structure together to form an integrated volute-type inoculation structure.
[0030] When the inoculation cup outlet conveying channel 9 is located below the seeding port position (i.e., the seeding position) of the seeder, the inoculation cup outlet conveying channel 9 is horizontal.
[0031] The seed inlet end 6-1 of the volute-type seed conveying channel and the seed outlet end of the volute-type seed conveying channel are separated by an isolation baffle 12.
