| Popis: | A coulter is one of the most important working elements of a grain seeder. Its operation affects not only the uniform distribution of the seeds but also the depth of their sowing. The manufacture of coulters without a seed covering device can be considered a disadvantage of the present coulters. This results in partial and uneven coverage of the seed furrow only caused by sloughing soil from the furrow walls, following the coulter disks. In this case, the partially and unevenly placed seeds can be distributed in the soil with different depths, etc. In turn, this can lead to the seeding quality and crop yields decrease. The research presented in this article is oriented towards improving the quality of sowing of grain crops by upgrading the coulter working process with furrow covering devices. These studies are relevant and of high economic importance to the agro-industrial complex of the Russian Federation. This article presents the design and operating principle of the developed coulter with furrow covering device. When using it, the seeding-down only by falling soil from the furrow walls is avoided; complete and uniform furrow covering without seed displacement together with the soil is provided; the most uniform seed distribution over the length of the furrow and the sowing depth is ensured. |
