Air duct seed selection reel type seed cell precision seeding device

Abstract

The invention relates to an air duct seed selection reel type seed cell precision seeding device. The device comprises a seed selection mechanism, a seed filling mechanism and a seed filling-unloadingmechanism; the seed selection mechanism comprises a seed cleaning part and a sorting part; the seed filling mechanism comprises a mechanical translational drive mechanism fixedly connected to the side wall of a seed filling box, the side, opposite to the mechanical translational drive mechanism, of the seed filling mechanism is provided with a translational sliding piece structure, and a supporting sliding piece of the translational sliding piece structure slides in a U-shaped sliding groove; the seed filling-unloading mechanism comprises a soft reel, the two sides of the reel are positionedthrough rotating shafts, the middle of the reel is divided into an upper layer structure and a lower layer structure, the upper layer structure and the lower layer structure are both provided with thesame seed cells, seeds firstly fall into the seed cells of the seed filling box through the upper layer structure to complete seed filling, the reel rotates until the seed cells of the lower layer structure correspond to the seed cells of the seed filling box, and seed falling is completed.

Description

technical field [0001] The invention relates to a sowing device, in particular to an air duct seed selection reel type hole 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 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 ...

AI Technical Summary

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, 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
