Studies show that due to variability of physical and mechanical properties of the soil, hard lumps are formed when carrots are harvested by diggers and remain inseparable from the tubers complicating the sifting process, which leads to overloading of machines. A lattice loosening working part that improves the separating ability of the digger elevator has been developed. The research objective is to seek rationale for the parameters of the lattice ripper of the carrot digger, which ensures a uniform distribution of the soil pile along the width of the elevator and improves complete separation of impurities with minimal damage to root crops. (Materials and methods) The study looked into the geometrical, kinematic parameters of the lattice ripper of the carrot digger. After investigating the physical and mechanical properties of the carrot bed, the research could provide theoretical rationale for the design parameters of the mechanism and its kinematic indicators. (The research results and analysis) It has been found that when the lattice cultivator interacts with the soil layers on the elevator, soil clods get destroyed and the soil gets loosened at the following parameters: the radius of the cultivator - at least 9.5 centimeters, the height of the shaft - 20 centimeters, the loaded part of the foot of the cultivator - 6 centimeters, the width of the grid ripper - 47 centimeters. (Conclusion) It has been revealed that lattice rippers help separate carrot root crops quickly from the soil layer without any damage or loss. It appears that the rotation speed of the grid ripper should not exceed 2.5 meters/second, the kinematic mode of the intensification agent of separation - 2.5, and the radius of the ripper should be at least 9.5 centimeters.

Abstract. The authors noted that in order to increase the energy-saturated equipment technical readiness, reduce its operation costs and ensure full use of the resource, it is necessary to quickly assess the current technical condition. The authors have created a counter-indicator prototype for high-precision control of gearbox technical condition. (Research purpose) To formulate a proposal for developing a system for the remote monitoring of gearbox technical condition applicable to the Kirovets tractor family. (Materials and methods) To increase the precision level of traceability and technical condition detection, a system of diagnostic tools was proposed based on the developed counters-indicators, which take into account design features when determining diagnostic parameters. (Results and discussion) It was shown that to assess the gearbox technical condition, it is necessary to use additional monitoring systems, obtain information for calculating the residual life, when using direct measurements and having a possibility of the ongoing monitoring over the actual change in the gearbox units diagnostic parameters. The authors studied the options for using meter-indicators to minimize group II and III failures during operation.(Conclusions) It was identified that in order to increase the level of gearbox operational reliability, it is necessary to introduce a system of counters-indicators. The authors revealed the possibility of monitoring the individual unit technical condition in accordance with the specified indicators, as well as in order to prevent operation in emergency (abnormal) modes.

Annotation This article examines the study of strength properties of polymer composite material, based on 3D-printed frame produced by FDM technology. The printing material is ABS plastic (acrylonitrile butadiene styrene). After the printing samples frames were soaked in pure epoxy resin with various hardeners. Subsequent curing went in two modes. After that, tensile tests were performed. The strength of impregnated, non-impregnated (clean frame) samples and samples made of pure resin was compared. Tests have shown that the strength of impregnated samples exceeds the strength of non-impregnated ones, but obtained strength value of impregnated samples were far from the expected theoretical values. It was found that low strength is associated with poor quality of the impregnation.
