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 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

[0032] Seed selection agency part:

[0033] 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.

[0034] Part of the filling mechanism:

[0035] see figure 1 , the drive motor 15 is installed on the frame 16; the gear one 14 is installed on the drive motor 15, the gear two 13 is installed on the eccentric support 12, and is concentric with the main shaft of the eccentric support 12, the gear one 14 and the gear two 13 form a gear pair, for The driving m...

Embodiment 2

[0044] This embodiment is aimed at seeds with larger hole sizes or low-density sowing, such as vegetable seeds. see Figure 7 , the bottom of the seed filling box 10 is directly provided with a plug tray 19 . 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 Background.

[0045] In this embodiment, the structure of the seed drop platform and the seed drop stand is abandoned, which saves materials a...

Abstract

The invention relates to a mechanical translational gear type precision seeding device. The device comprises a seed selection mechanism, a seed filling mechanism and a seed filling-unloading mechanism, wherein the seed filling-unloading mechanism comprises a fixedly arranged small motor, a power output shaft of the small motor is horizontal, the power output shaft 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; the upper rack frame is fixedly connected with an upper cover plate, and the lower rack frame is fixedly connected with a lower bottom plate; the upper connecting gear and the lower connecting gear are both partial-toothed gears, and only one of the upper connecting gear and the lower connecting gear is in a meshed state at the same moment; the small motor drives the upper cover plate and the lower bottom plate to reciprocate through the two rack frames respectively to achieve seed filling and seed unloading. In the seed selection process, seed cleaning and seed selection operation can be completed at one time to obtain seeds meeting the seeding requirements; in the seed filling-unloading connection process, the problem of unreliable mechanism caused by the use of a return spring is avoided.

Description

technical field [0001] The invention relates to a sowing device, in particular to a mechanical translational gear type precision sowing device. Background technique [0002] The document number is CN208987276U, and the Chinese patent document whose disclosure date is June 18, 2019 discloses a mechanical translation type special-shaped seed single-grain precision sowing device, 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, 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 link between 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.
