Embodiment 1
[0035] Seed selection institution:
[0036] See Figure 1-4 , The funnel 1 is installed on the seed cleaning rack 5; the bottom of the funnel 1 is equipped with a guide groove, and the sowing rate adjustment plate 2 is installed in the bottom guide groove of the funnel 1; the fan 3 is installed on the seed cleaning rack 5; the baffle 4 is installed on the cleaning rack. Seed rack 5; conveying pipe 6 is installed on seed cleaning rack 5; three-level sorting box 9 is installed on seed filling box 10; second-level sorting box 8 is installed on three-level sorting box 9; first-level sorting The box 7 is installed on the secondary sorting box 8.
[0037] Part of the filling institution:
[0038] See Figure 1-6 , The drive motor 15 is mounted on the frame 16; the gear one 14 is mounted on the drive motor 15, the gear two 13 is mounted on the eccentric support 12, concentric with the main shaft of the eccentric support 12, the gear one 14 and the gear two 13 form a gear pair, which is Th...
Embodiment 2
[0047] This embodiment is aimed at seeds with a large hole size or low-density sown, such as vegetable seeds. The difference between this embodiment and the first embodiment is that there is no seeding rack and seeding platform. See Figure 7 , A plug tray is directly arranged at the lower part of the seed filling box 10. Mainly for low-density sown seeds, such as cucumber, tomato, pepper and other vegetable seeds, choose an eccentric support with a small eccentricity to complete the low-amplitude and high-frequency filling process. Do compound movement within the projection range of the hole size. When the upper cover is closed, the lower bottom plate opens, and the seeds fall freely into the hole to complete the seeding process; the reciprocating linear movement of the upper and lower bottom plate opening and closing mechanism of the filling box can be Refer to the closest prior art cited in the background art.
[0048] This embodiment discards the planting platform and planti...
