Problems solved by technology

[0003] 1) In the seed selection process, the sorting box has a circular structure, and the space is not fully utilized, and the problem of insufficient seed supply from the sorting box to the filling box may occur;
[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 a driving wheel and the other three are driving wheels. During work, it is easy to Self-locking phenomenon occurs, 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 accuracy. requirements;
[0005] 3) In the connection between filling and unloading, the reset of the upper cover and the lower bottom completely depends on the return spring, and the reliability is difficult to guarantee; the material of the upper cover and the lower bottom is opaque, and it is not convenient to observe the seeds in the process of filling and unloading status

Embodiment 1

[0030] Seed selection agency part:

[0031] see Figure 1-5 , the third-level sorting box 3 is installed on the seed filling box 4; the second-level sorting box 3 is installed on the third-level sorting box 3; the first-level sorting box 1 is installed on the second-level sorting box 2;

[0032] Part of the filling mechanism:

[0033] The driving motor 9 is installed on the frame 10; the gear one 8 is installed on the driving motor 9, the gear two 7 is installed on the eccentric support 6, and is concentric with the main shaft of the eccentric support 6, and the gear one 8 and the gear two 7 form a gear pair for driving Motor 9 transmits power to eccentric support 6; Eccentric support 6 is installed on the frame 10; Then, between the main shaft of the eccentric support 6 and the frame 10, the rotating motion is completed through the frame bearing 16; the support bearing 15 is fixedly connected with the support frame 5, and the rotation between the eccentric shaft of the ecce...

Embodiment 2

[0038] The difference from Embodiment 1 is: see Figure 7 , In the present embodiment, the seed drop platform is not provided, and the hole tray 14 is directly provided at the bottom of the seed filling box 4 . It is mainly aimed at low-density sowing seeds, such as vegetable seeds such as cucumber, tomato, and pepper, etc., without setting up a seed drop frame and a seed drop platform. Abandoning the seed drop platform and seed drop stand structure saves materials and reduces the difficulty of installation; the distance between the hole plate and the lower bottom plate is relatively short, which reduces the uncontrolled travel of seeds and prevents the seeds from being too long due to initial velocity and free fall distance And fly out of the hole range; after shortening the distance between the hole plate and the lower bottom plate, the overall structure is more compact.

[0039] All the other are the same as embodiment one.

Abstract

The invention relates to a reel type accurate hole-seeding device. A seed filling and unloading mechanism comprises a small motor which is fixed relative to a seed filling box and a reel, the reel ismade of a soft material, two sides of the reel are located through rotating shafts, the middle of the reel is divided into an upper layer structure and a lower layer structure, and the upper layer structure and the lower layer structure are located on two sides of a bottom plate of the seed filling box and are both installed in guide grooves at the bottom of the seed filling box; the upper layer structure and the lower layer structure are both provided with the same holes, the small motor drives the reel to rotate through one rotating shaft, when the holes at the upper part of the reel are aligned with the holes of the seed filling box, the holes at the lower part of the reel are staggered with the holes of the seed filling box, seeds conforming to the size of the holes fall into the holesof the seed filling box at the moment, the seed filling process is completed, and when the holes at the lower part of the reel are aligned with the holes in the seed filling box, the holes at the upper part of the reel are staggered with the holes of the seed filling box, and at the moment, seeds fall into the holes of the lower bottom plate and fall from an inside pipeline of a seed falling platform to a holed tray. The seed filling process and the seed unloading process are periodically linked up, and continuous work can be realized.

Description

technical field [0001] The invention relates to a sowing device, in particular to a precision sowing device for scroll-type hole seeds. 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, and the space is not fully utilized, and the problem of insufficient seed supply from the sorting box to the filling box may occur; [0004] 2) In the seed filling link, 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 a driving wheel and the other three are driving wheels. During work, it is easy to Self-locking phenomenon occurs, which affects the reliability and s...
