Description

technical field

[0001] The invention relates to a sowing device, in particular to an air duct seed selection translational 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, and the problem of insufficient seed supply from the sorting box to the seed filling box may occur; 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 ...
