Abstract

In this paper, we propose the substantiation procedure of a technological complex design on the example of a seeding complex. As a result of performed research, design of the seeding complex for grain crops has been improved using non-standard devices and typical parts that provide: reduction in the time of seeding and energy consumption, possibility of using the seeding complex as a cultivator and a disk harrow. Analysis of computational research results allowed us to specify the following parameters: disc angle of 15 degrees, while the specific traction resistance of the seeding complex does not exceed 3.44 kN/m on the stubble background, and 3.19 kN/m on the fallow background. Field studies of the developed complex has shown that at the given seeding depth (with the variation ± 1cm) the accuracy is 83.5 ... 84.2 %. Optimum quantity of plants of grain crops per unit area is provided under the following conditions: bucket volume 7,2 dm³, distance between buckets 0.21 m; speed of the bucket elevator is 0.12 m/s. The proposed design of the seeding complex is recommended to be used for combining several operations: soil preparation, sowing of cereals and soil packing.
