Description

Technical Field

[0001] The invention belongs to the technical field of sliding doors, and in particular relates to a no-tillage sowing machine capable of sowing multiple forage grass seeds at the same time. Background Art

[0002] The reseeder is a special seeding machine for sowing grass seeds on natural grasslands. It is used to reseed high-quality grass seeds without destroying the original vegetation, so as to restore the production capacity of natural grasslands and improve the quality of forage. The restoration of grassland ecology is a long way to go. The main reason is the lack of grassland restoration equipment and technology, and the lack of systematic restoration experience. In order to improve the ecological environment of my country's grasslands, promote the benign cycle of grassland ecology, curb grassland degradation, and achieve grassland ecological restoration and productivity improvement, it is necessary to develop key equipment suitable for natural grassland vegetation restoration and construction, and form grassland ecological restoration. In modern agricultural production, no-till reseeding technology is widely used in forage planting, grassland ecological restoration, and agricultural sustainable development because of its advantages such as reducing soil tillage times, protecting soil structure, improving soil fertility, and saving water.

[0003] Although the existing no-tillage seeder is provided with a seed box for storing seeds, it lacks an effective turning mechanism, which causes the seeds to be easily piled up in the seed box and has poor fluidity, which easily causes uneven sowing or missed sowing, and is also prone to blockage during discharge. Traditional no-tillage seeders can usually only sow a single type of forage seeds, and cannot meet the needs of diversified and mixed sowing in modern agricultural production. In terms of furrowing, the no-tillage seeder in the prior art often adopts a fixed furrowing depth, which cannot be flexibly adjusted according to soil conditions and the sowing needs of forage seeds, resulting in poor sowing effects. Finally, during the furrowing process, the adhesion between soil particles is large, the furrowing resistance is large, the furrowing knife is easily worn, and its service life is reduced. For this reason, the present invention provides a no-tillage seeder that can sow multiple forage seeds at the same time. Summary of the invention
