| Popis: | For sowing grain crops on stubble, stubble seeders with tine coulters are used, which perform technological operations in one pass. However, they do not meet the requirements of the agricultural machinery to ensure an even distribution of seeds in the sub-spear space. The subsoil no-drill planting creates the most favorable conditions for growth and development of cultivated crops and at the same time, grain crop yields are increased on average by 10…30%. Using no-drill planting, seeders equipped with spear coulters with spreaders for no-drill subsoil seeding provide the best quality and distribute the seeds evenly over the field. The article proposes the original design of the seed drill coulter for no-drill planting, which provides an even seed distribution over the feeding area. As a result of the theoretical researches the optimal parameters of the diffuser for the grain drill coulter are determined and the dependence between the unevenness on the test parameters of the diffuser and the height of the pendulum spreader, the base diameter are obtained. The purpose of this research is to develop the design and rationale of parameters of the grain drill for subsoil no-drill planting, the use of which will reduce the uneven distribution of grain crops seeds or mineral fertilizer granules. |
