The paper presents the results of studies of grain crops row sowing method agrotechnical indicators after the modernization of the working bodies of the SZS-2.1 seeder-cultivator. The SZS-2,1 stubble cultivator seeder has found wide application in the arid regions of the Republic of Buryatia, whose soils are prone to wind erosion. This seeder provides a combination of pre-sowing cultivation, sowing grain crops, applying mineral fertilizers to the sown rows and rolling them on stubble backgrounds, that is, in fields that have been processed since autumn with flat-cutting tools or have not been cultivated at all. Sowing with these seeders with 23 cm row spacing in a row method is the main method of sowing spring wheat in the soil conservation agriculture system. Routine sowing on soils of light texture, subject to wind erosion, causes thickening of plants in a row, which leads to irrational use of the feeding area by plants, increased weediness of crops between rows and, ultimately, to a decrease in yield. A distributor for the coulter has been developed, where the seeds are fed to the distributor. Then, reflecting from the distributor, the seeds are evenly dispersed in the opener under the plow space. Also, instead of serial wedge-shaped packer rollers, ring-spur rollers of the 3KSH-6 type are installed on the seeder. In addition, continuous rolling provides the necessary contact of seeds with the soil, preserves soil moisture and helps to attract it from the lower layers. Thus, the modernization of the SZS-2.1 seeder made it possible to substantiate subsurface-spread strip sowing with continuous rolling, which ultimately led to an increase in grain yield by 10-15%.

In this paper, we present a novel method of using the continuous rolling to fabricate three-dimensional sheet metal. The core bendable roller is composed of the flexible axis and the controllable equipment. The transversal shape of the sheet metal can be realized by regulating the controllable equipment to make the axis of bendable roller bent; the longitudinal shape is formed by driving the three bendable rollers rotated and the top roller making a displacement synchronously. Some experiments were performed and typical 3D surface parts were formed. Based on the results of the experiments, the effects of the thickness and the rolling times are discussed. The results of the research will be beneficial to define the parameters and perfect the theory of continuous multipoint forming of multiform 3D parts.

This paper used the finite element software to simulate the process of the heavy rail rolling deformation between the UR and ER racks. It studied on the stress distribution law of the universal mill pass, the relationship between the universal mill unbalanced rates of velocity and tension changes of the rack, effect of the universal mill unbalanced rates of velocity on the change of the rolling geometric dimensions caused by the unbalanced rates of velocity. The research can guide the adjustment of the dimensional accuracy of the rail’s universal rolling.
