Problems solved by technology

[0003] 1) In the seed selection process, the sorting box has a circular structure, the hole layout efficiency is low, and the space is not fully utilized, which may cause insufficient supply of seeds from the sorting box to the seed filling box; the selected seeds need to remove sand and dust in advance and other impurities, increasing the workload;
[0004] 2) In the seed filling process, four eccentric wheel structures are used to support the seed filling box, which requires high installation accuracy. If there is an installation error, since one of them is a driving wheel and the other three are driven wheels, when working, Self-locking phenomenon is prone to occur, which affects the reliability and stability of the equipment, and there is a risk of early damage; according to different seed requirements, if the eccentric support is replaced to adjust the rotation diameter of the seed filling box, four eccentric supports need to be replaced at the same time, which greatly increases the installation cost. Accuracy requirements;
[0005] 3) In the connection link of filling and unloading, the reset of the upper cover and the lower base completely depends on the return spring, and the reliability is difficult to guarantee

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...

Abstract

The invention relates to an air duct seed selection translational precision seeding device. The device comprises a seed selection mechanism, a seed filling mechanism and a seed filling and dischargingmechanism; the seed selection mechanism comprises a seed cleaning part and a sorting part; the seed filling mechanism comprises a mechanical translation driving mechanism fixedly connected with the side wall of a seed filling box, the opposite side of the mechanical translation driving mechanism is provided with a translation sliding sheet structure, the translation sliding sheet structure comprises a U-shaped sliding groove and a support sliding sheet which are fixedly arranged, and one end of the support sliding sheet can slide in the U-shaped sliding groove; a power output shaft of the seed filling and discharging mechanism is provided with a lower connecting gear and an upper connecting gear, the upper connecting gear is meshed with an upper rack frame, and the lower connecting gear is meshed with a lower rack frame; a small motor drives an upper cover plate and a lower bottom plate to reciprocate through the two rack frames separately to achieve seed filling and discharging.

Description

Technical field [0001] The invention relates to a seeding device, in particular to a precision seeding device for air channel selection and translational movement. Background technique [0002] The document number is CN208987276U, and the publication date of the Chinese patent document on June 18, 2019 discloses a mechanical translational type single seed precision seeding device for special-shaped seeds, which has the following technical problems: [0003] 1) In the seed selection process, the sorting box has a circular structure, the hole layout efficiency is low, and the space is not fully utilized, and the problem of insufficient seed supply to the filling box may occur; the selected seeds must be removed in advance of sand and dust Wait for impurities and increase workload; [0004] 2) In the seed filling process, four eccentric wheel structures are used to support the seed filling box, which requires high installation accuracy. If there is an installation error, one of them is...
