Embodiment 1
[0030] Seed selection agency part:
[0031] see Figure 1-4 , the funnel 1 is installed on the seed clearing frame 5; the bottom end of the funnel 1 is provided with a guide groove, and the seeding rate adjustment plate 2 is installed in the guide groove at the bottom end of the funnel 1; the fan 3 is installed on the seed clearing frame 5; On the seed rack 5; the conveying pipe 6 is installed on the seed clearing rack 5; the three-stage sorting box 9 is installed on the seed filling box 10; the second-stage sorting box 8 is installed on the third-stage sorting box 9; Box 7 is installed on the secondary sorting box 8.
[0032] Part of the filling mechanism:
[0033] Drive motor 15 is installed on the frame 16; Gear one 14 is installed on the drive motor 15, and gear two 13 is installed on the eccentric support 12, is concentric with eccentric support 12 main shafts, and gear one 14 and gear two 13 form gear pair, for driving Motor 15 transmits power to eccentric support 12;...
Embodiment 2
[0040] What this embodiment is aimed at is that hole size is bigger, or the seed of low-density sowing, such as super rice, vegetable seed etc., the difference between this embodiment and embodiment 1 is: do not arrange seed drop frame and drop seed platform. see Figure 7 , the bottom of the seed filling box 10 is directly provided with a hole tray. Mainly for low-density sowing seeds, such as cucumber, tomato, pepper and other vegetable seeds, etc., the eccentric support with small eccentricity is selected to complete the low-amplitude and high-frequency seed filling process. The compound movement is performed within the projection range of the hole size. When the upper cover plate is closed, the lower bottom plate opens the door, and the seeds fall freely into the hole to complete the sowing process; the reciprocating linear motion of the opening and closing mechanism of the upper and lower bottom plates of the seed filling box can be See the closest prior art cited in the...
