The article presents the results of metallographic study of low-carbon 20 steel grade and high-carbon 70 and 65G steel grades upon carburizing, heat treatment, and laser hardening. The change in the microhardness through the depth of the surface layer of steels and their abrasion resistance upon hardening under different conditions has been measured. Optimal hardening conditions have been proposed for steels for cutting blades of tillage machines that enable the durability of the blades to be improved.
The present-day agriculture involves anthropogenic effects on the soil, including the compaction and overcompaction of soil horizons at depths up to 1.2 m. The plowing of the soil with moldboard plows to a depth of 0.3 m results in the formation of a plow pan (hardpan), which hampers the development of plant roots; the optimum soil density for most agricultural crops is ρ = 1.1-1.3 t/m3. There are supporters and opponents of deep subsoil plowing; only the plow horizon is the main object of studies. Chisel tools (subsoilers) have been studied on modernized models, which ensure the deep non-moldboard loosening to a depth of 0.30-0.45 m and more (down to 0.8 m) with the use of straight or slant shanks. Shank cultivators developed by the Siberian Research Institute of Mechanization and Electrification of Agriculture (SibIME), which penetrate to 0.30 m, were first used to control deflation. The American slant-shank subsoiler (Trade name, Paraplow) is the prototype of chisel implements. A range of tillage tools has been developed to form a ridged furrow bottom due to soil breakdown. Modernized tillage tools include breasts mounted on shanks for turning the upper (loosened) soil layer up to 0.20 m thick, as well as blades for cutting weeds, ridges, etc. Chisel modifications are mainly aimed at expanding their functional capabilities and decreasing the energy intensity of soil cultivation. The tests have confirmed the decrease of C, N and humus losses; the improvement of the water and air conditions in the soil; the prevention of erosion; the improvement of tillage quality parameters; the increase of tractor aggregate output; and the saving of up to 25% of motor fuel.
An enzymatic-cavitation method for the biological treatment of organic-containing wastewater and sludge treatment has been developed, according to which the air supply is carried out not by compressors, but rather ejectors. In addition, low-intensity cavitation is provided. The biological treatment of the wastewater has been performed at a temperature of 10-42 °C. The energy consumption of the process is reduced by six times, while the time of sludge treatment is 8–10 h at a pressure of 0.30-0.35 MPa. The treated sludge has some adsorptive properties.
Dampers and shock absorbers consisting of vertical concentric elastic shells are considered. The external and internal shells are made of hard rubber, while the middle shell is made of soft rubber. Independent action of the shells permits optimal loading and energy-efficient operation of the device.
Results of experimental studies of low-carbon steel 20 and high-carbon steels of types 70 and 65G after carburizing, heat treatment and laser hardening are presented. The variation of the microhardness of the surface layers of the steels and of their wear resistance due to different variants of hardening is determined. Optimum modes of treatment aimed at raising the strength and wear resistance are suggested for the steels used for working members of cultivating machines.
Blocked cutting takes place at the impact of soils on the subsurface level – without carrying of soil particles over the ground surface. Lumps of soil, condensed around the chisel of the tool due to air (elasticity modulus increases up to 40 MPa) and the impact supersonic waves, are formed and propagated at an angle of the natural slope (≈ 45°) and decompress the soil.
