Air duct seed selection translational precision seeding device

Abstract

The present invention relates to an air duct seed selection translational precision seeding device, comprising a seed selection mechanism, a seed filling mechanism, a seed filling-unloading mechanism; the seed selection mechanism includes a seed cleaning component and a sorting component; the seed filling mechanism includes a The mechanical translation drive mechanism fixedly connected to the side wall of the seed filling box is provided with a translation slide structure on the opposite side of the mechanical translation drive mechanism. The translation slide mechanism includes a U-shaped slide groove and a support slide fixedly arranged. One end of the supporting sliding piece can slide in the U-shaped sliding groove; the power output shaft of the filling-unloading mechanism is provided with a lower connecting gear and an upper connecting gear, the upper connecting gear meshes with the upper rack frame, and the lower connecting gear and The lower rack frame meshes; the small motor drives the upper cover plate and the lower bottom plate to reciprocate through the two rack frames to realize seed filling and unloading.

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 ...

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, 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 of them is the driving wheel and the other three are driven wheels. When working, Self-locking phenomenon is prone to occur, 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 cost. Accuracy requirements;

[0005] 3) In the connection 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
