Theoretical Substantiation of the Traction Resistance of the Ridge Seeder

Abstract

The analysis of the current state of the enterprises of the agro-industrial complex of Russia has shown that various energy-saving cultivation technologies of agricultural crops, including row crops on ridges, are being applied on a large scale. Mainly, such technologies imply a reduction in the number of technological operations performed, the replacement of sowing on pre-treated soil with sowing according to minimal technology or no-till at all. When implementing comb sowing of row crops, the problem of energy saving remains relevant. Keeping in mind the design features and the operation principle of tillage rollers, it can be stated that they are designed mainly for the destruction of soil lumps and compaction of soil on a flat field before or after sowing. There is a problem of high-quality rolling of soil ridges formed simultaneously with the sowing of row crops. (Research purpose) The research purpose is to substantiate the traction resistance of a roller aggregated with a combed roller theoretically. (Materials and methods) The algorithms used to assess the quality of the rollers are imperfect, for reliable justification of the optimization parameter, it is necessary to solve a number of issues, in particular, the methodology for determining the traction resistance of rollers designed for the final creation of soil ridges by simultaneous action of spherical disks and conical wheels on their sides. A skating roller has been developed for the finishing operation of forming a soil ridge with the required parameters and density simultaneously with sowing, the novelty of which is confirmed by patents of the Russian Federation No. 194330, No. 194348, No. 196712. (Results and discussion) The article presents the process of forming a soil ridge by a roller, and the justification of the traction resistance of a ridge drill roller. A vertical load artificially created by a spring additionally acts on the roller of the comb seeder, this load evenly spreads to the conical core and spherical disks of the roller. (Conclusions) The total traction resistance of the roller of the comb seeder is affected by the weight of the conical wheel, frame, additional spring compression load, the size of the rolling wheel and spherical discs, the speed of the roller, as well as the physical and mechanical properties of the soil.
