The article presents the results of theoretical and experimental studies of rolls with spiral winding in the process of transportation of sugar beet mother plants to planting unit. The results of studies allow to substantiate the kinematic parameters of roller transporting device at the given rate of planting.
The article presents the design of experimental digger for tuberous roots, describes its features and operational principle. The basic data and results of experimental researches of the digger are given.
The paper considers the design of seeder for grain crops with bladed and milling working organs.
The paper describes a mathematical model for wheeled vehicle with automatic transmission of «torque converter - coupling - gearbox» type. In order to compare this type of transmission and mechanical one with same number of gears and ratios, optimal characteristics of torque converter for considered vehicle are selected. The paper presents the results of simulation of wheeled vehicle moving for both variants of gearbox in conditions involving variable resistance and moving velocity assigned by driver. Efficiency of hydromechanical transmission use is estimated.
The article presents the results of comparative evaluation of the efficiency of energy costs for technological process of ploughing units on the basis of the serial tractor (K-701), the gas-turbine engined one (K-701 Turbo) and the ПЛН-9-35 plough.
The article reviews the designs of extruders and screws. It describes the main known methods of determination of material quality. As a technical solution improving the design of extruder, a double-threaded screw that should be installed in the material forming zone is proposed.
The article presents a developed electromechanical motion control system for wheeled tractors using GPS and GLONASS satellite navigation systems, a transmission system of differential corrections of the satellite signal, the results of laboratory and field tests of the control system.
The article is devoted to finding ways to improve the crumbling of soil layer by rotary rippers through the use of double-drum schemes providing kinematic connection of drums.
The article analyzes the traction power of small-scale mechanization means of agricultural engineering when performing agrotechnological operations.
