“…Works [16; 17] substantiate the design, kinematic and technological parameters of screw working bodies by considering their functional purpose. The possibility of using a helical surface for the manufacture of conveyor working bodies was considered in [18]. The theoretical foundations of the design and construction of linear screw surfaces are presented in [7; 19].…”

Existing designs of screw working bodies of transport and processing machines cannot always provide the required performance and avoid overloading, which causes deformation and damage to parts of the mechanisms. Thus, it is necessary to establish new efficient screw working bodies that would ensure the execution of the technological process. The purpose of the study was to substantiate and explore the design and methodology for calculating the main structural-power parameters of the developed screw loader, to synthesise screw loaders using the method of morphological analysis to obtain designs of mechanisms with better technical and economic characteristics. The methods of surface theory, analytical and differential geometry, computer graphics and mathematics were used to conduct the research. As a result of theoretical and experimental studies, the designs of screw conveyors with hopper loading and screw conveyors with nozzle loading are presented. In addition, a classification of loaders for screw transport and technological mechanisms is presented. The dependencies for calculating the design of screw conveyor loaders are determined. The synthesis of loaders and mixers by the method of morphological analysis was performed to obtain designs of mechanisms with the best technical and economic characteristics and competitive designs of mechanisms were established. A system of coding and synthesis of structural elements and mechanisms of screw implements with improved technological properties is proposed, and competitive designs of screw implement that perform technological processes efficiently and effectively are selected. A methodology for calculating the main structural and power parameters of a screw loader has been developed, which allows for determining the parameters of a screw loader. The materials of the research can be used in further studies of screw conveyors and, in particular, screw loaders to determine their design, technological, energy and power parameters

“…For this purpose, new designs of bridge power facilities were developed in researches [1][2][3], and their theoretical and experimental studies were carried out. According to them, the same transport and technological tracks for the movement of vehicles and energy vehicles are used for tillage, sowing of plants, spraying and harvesting [4][5][6]. In the works [7][8][9], it is described the process of formation of compacted and aligned traces of a constant technological track that consists in its laying on the field area with a given step, either as a result of repeated Methodology for experimental study of soil microrelief... passes of agricultural machinery, or with the help of special tools [7][8][9].…”

The study of issues related to the research of the soil's state on the surface of the most constant technological track is relevant, since the movement of running wheels along narrow tracks determines the traction and coupling properties of the machine-tractor units, their vibrations, the stability of movement and the controllability of movement. The рurpose of this study was to increase the efficiency of the process of profiling the microroughnesses of the soil surface located in areas that form a track along which the running wheels of machine-tractor units will move, by substantiating a new scheme of an automated profilograph and developing methods for its use. For this study, modern methods of experimental researches based on IT technologies were used. In particular, an automated complex has been developed for measuring and evaluating the microprofile of soil surface irregularities on the very track of the tramline. The results of experimental studies in this matter have shown that the standard deviation of the soil surface irregularities reaches ±0.84 cm. This gives reason to consider the harmonic components of these functions as damped, having normalized correlation functions. The graphs constructed using PC have showed that most of the dispersions of soil surface irregularities on the ruts are concentrated in the range of 0…0.3 cm −1 . It has been established that the generator of the formation of irregularities in the longitudinal profile of traces of a permanent technological track acts as parameters of the treads of the wheels of machines moving along it. The obtained results of the study can be used when selecting the protectors of pneumatic tires of the running wheels of machine-tractor units moving on two tracks
