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 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

Abstract

The invention relates to a mechanical sliding sheet translation type precise seeding mechanism which comprises a seed selecting mechanism, a seed filling mechanism and a seed filling-discharging mechanism. The seed filling mechanism comprises a mechanical translation driving mechanism fixedly connected with the side wall of a seed filling box, a translation sliding sheet structure is arranged on one side opposite to the mechanical translation driving mechanism and comprises a U-shaped sliding groove in fixed arrangement and a supporting sliding sheet, and one horizontal end of the supporting sliding sheet is fixed on the side wall of the seed filling box while the other end of the same can slide in the U-shaped sliding groove; a power output shaft of a small motor of the seed filling-discharging mechanism is horizontal, an upper linkage gear is meshed with an upper rack frame, a lower linkage gear is meshed with a lower rack frame, the upper rack frame is fixedly connected with an upper cover plate, and the lower rack frame is fixedly connected with a lower bottom plate; each of the upper linkage gear and the lower linkage gear is a non-full-tooth gear, and only one of the upper linkage gear and the lower linkage gear is in a meshed state; the small gear respectively drives the upper cover plate and the lower bottom plate to be in reciprocating motion through the two rack frames to realize seed filling and seed discharging.

Description

technical field [0001] The invention relates to a sowing device, in particular to a mechanical sliding plate translational precision sowing device for 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 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 affec...
