CONSTRUCTION OF GRAIN SEEDER COULTER WITH A HINGE JOINT OF A SEED GUIDE AND A SOIL CULTIVATOR WITH THE COULTER BODY

Abstract

The even distribution of seeds along the length and depth of the row mostly depends on the coulter, since it is one of the most responsible working parts of the seeder for sowing agricultural seeds. The disadvantages of the available coulters include the adhesion of soil to the discs, which leads to poor compaction of the bottom of the furrow and shifting of seeds along the furrow, while the even distribution of seeds along the depth and the length of the furrow is disturbed. Moreover, modern coulters have mainly open type seed guides, which leads to the drop of seeds not to the bottom of the furrow, but to its walls, while the even distribution of seeds along the depth and along the length of the furrow is disturbed. All these disadvantages lead to a decrease in crop yields. The conducted studies aimed at improving the quality of sowing grain crops by improving the technological process of the coulters of a grain seeder with a hinge joint of the seed guide and the soil cultivator with the coulter body are relevant and have high economic and economic importance for the agro-industrial complex of the Russian Federation. The article presents the device and principle of operation of the designed grain seeder coulter with a hinge joint of the seed guide and soil cultivator with the coulter body. When the coulter operates, the seeds are embedded not only due to the crumbling soil from the walls of the furrow caused by the coulter disks, but a complete and even filling of the furrow with seeds is carried out without displacement along with the soil, and also provides a more even distribution of seeds along the length and the depth of the furrow.
