Seed discharging mechanism

Abstract

The invention discloses a seed discharging mechanism which comprises an upper partition plate, a lower partition plate, an upper seed discharging door, a lower seed discharging door, an upper driving rod, a lower driving rod and a second connecting rod. The upper partition plate and the lower partition plate are arranged in a layered manner in the up-down directions, a seed collecting cavity is formed between the upper partition plate and the lower partition plate, an upper seed discharging opening is formed in the upper partition plate, a lower seed discharging opening is formed in the lower partition plate, and the upper seed discharging door is obliquely hinged into the upper seed discharging opening, so that the upper seed discharging opening can be opened; the lower seed discharging door is horizontally hinged into the lower seed discharging opening, so that the lower seed discharging opening can be closed; the upper seed discharging door and the lower seed discharging door are connected with the second connecting rod by the upper driving rod and the lower driving rod; the second connecting rod can upwardly move and drives the upper seed discharging door and the lower seed discharging door to upwardly rotate, the upper seed discharging opening can be correspondingly closed, and the lower seed discharging opening can be correspondingly opened. The seed discharging mechanism has the advantages that the seed discharging mechanism not only can be used for sowing large-grain seeds of rice, wheat\corns and the like, but also can be used for sowing small-grain seeds of rapeseeds, sesame and the like, and is convenient to operate and high in seed sowing precision.

Description

[0001] Technical field: [0002] The invention relates to a seeding mechanism. [0003] Background technique: [0004] The seed meter is one of the important parts of the seeder. Its function is to guide the seeds in the seed box of the seeder into uniform seeds, so as to control the sowing amount and achieve uniform sowing. The existing seed metering devices are generally wheel-type seed metering devices. The seed metering device with this structure cannot be used for sowing seeds with large size differences at the same time, that is, the seed metering device suitable for large seeds cannot be used for sowing small seeds. seeds and vice versa. [0005] Therefore, it is necessary to improve the prior art to solve the deficiencies of the prior art. [0006] Invention content: [0007] The present invention provides a seed-discharging mechanism in order to solve the above-mentioned problems in the prior art. [0008] The technical solutions adopted in the present inventio...
