Reel type hole precision seeding device

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...

AI Technical Summary

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
