Invention entitled ‘Seed drill, especially for sowing grains and rapeseed’ (Pat.225944/P.409445)

Description:

The object of the invention is a seed drill, especially for sowing grains and rapeseed, which can be mounted on a tractor or a cultivation tool.

The seed drill according to the invention eliminates the inconvenience known from other constructions, as it is equipped with a roller which compacts the soil in strips in front of the coulters and at the same time drives the sowing roller through gears. Such a seed drill can be operated individually or in combination with a cultivating tool, which does not need to be equipped with a rear shaft. The roller of the seed drill, made up of a series of wheels and located underneath the hopper, ensures effective drive of the sowing roller and strip compaction of the soil in front of the coulters. A characteristic feature of the seed drill is also the correlated alignment of the roller wheels, coulters and scraper tines.

With this positioning of the disc coulters, rows of seed are sown in the wheel tyre-compacted tracks and the tines scatter the soil that has not been compacted by the wheels and provide good seed coverage. Sowing the seed in the strip compacted soil also ensures even emergence conditions in all rows.

Benefits:

• the seed drill is equipped with a compacting roller, which allows the tool to be used without the need for aggregation with a cultivating machine,
• the drive of the sowing roller is carried out internally via the packer roller,
• the mutual correlation of the individual components of the seed drill enables precise sowing in compacted soil and adequate seed coverage

Status of legal protection:

The technology consists of patent Pat.225944 granted by the Patent Office of the Republic of Poland, in force from 10 September 2014.

Property rights to the invention are vested 100% in the Łukasiewicz Research Network – Poznan Institute of Technology.
