The operational process of sowing seeds of both grain and leguminous crops imposes a number of strict requirements not only on the designs of sowing machines, but also to the parameters of their operation. Currently, mechanical seeding machines have become widespread, among which roller type devices are the most common [1], however, despite their main advantages, such as simplicity of design and low cost of production, they have a number of disadvantages. When working with roller devices, the following problems often arise: unsatisfactory layout of the seed material along the length of the row (uneven sowing pitch), instability of the general seeding rate and injury to the seed material, as a result of which all this will lead to an increase in seed consumption and a decrease in their germination. To eliminate the mentioned above disadvantages, scientists and engineers are working on improvement of the technological process of seeding and the designs of seeding machines. One of the most promising areas of improvement of the seeding machine is to change the profile of the grooves of sectional rollers.
The article describes a designed seeding machine with a modified shape of the groove profile of the sectional roller. This seeding machine is designed for sowing seeds of grain and leguminous crops by the example of seeds of soft winter wheat of the cultivar Fotinya. The functional diagram of the operation of this sowing machine is based on the fact that the modified shape of the groove provides a more uniform layout of seeds along the length of the ridge. The use of a modified shape of the roller groove leads to an increase in the consistancy of the overall seeding rate and a decrease in the injury rate of the seed material.
Keywords: seeding roller, seeding machine, grain and leguminous crops, seeds, seed drill.
