In recent years, research has been underway to create working bodies of excavation machines that allow digging soil at higher speeds. One of these new types of machines are excavation and transport machines with an inertial bottom discharge rotor. The paper presents the results of studies of high-speed digging and proposes a method for determining the average values of the energy intensity of soil transportation, and the proposed equations can be recommended for calculating the inertial rotor. The table of costs of specific energy consumption and productivity from the speed of rotation of the rotor at constant chip sizes is given. The analysis of studies showed that the energy intensity increases with an increase in the speed of rotation of the rotor, and the productivity grows according to a linear law. The inertial-type rotor during the test proved to be quite efficient, and the performance of the tested rotor is four times higher than that of the existing gravity-type rotor.

Industrial robots cover most of the field of technology and are most successfully applied in machining, in motion modelling, in capturing and moving objects of research. In recent times, the complexity and variety of industrial robots and robotic manipulators have increased significantly. These are purposefully designed to attain a much greater level of independence than what is seen in conventional mechanical manipulators. In this article the classification of different configurations of manipulators and analysis of manipulators with artificial vision on the existing research of scientists is conducted. Also, the article analyzes the development of a manipulator with six degrees of freedom and the use of analytical methods to analyze the geometric structure of 3D data for optimal object recognition.

Numerous studies have established that the damage to the lower surface of hot-rolled strips is mainly due to their friction against rollers of mill rollers. In this case, the probability of scoring, scrapes and other mechanical damage increases otherwise severe wear on the surface of the rollers, improper installation and jamming. This also applies fully to the pulling and forming rollers of the coilers. On modern broadband mills the following measures are used to prevent damage to the surface of hot-rolled strips: reduce the distance between the axes of adjacent rollers; Increase the accuracy installation of rollers in the horizontal plane; apply the individual drive of each roller; provide a smooth increase in the speed rotation of the rollers along the length of the withdrawing roller table; increase the wear resistance of rollers. A prerequisite for preventing damage to the surface of hot-rolled strips is also the maintenance of a high level technical condition of the mill equipment, which includes inspections of wiring armature bars, roller conveyor rollers and other units for each transshipment, timely replacement and repair of individual parts and assemblies (primarily roller conveyors, interroller plates, etc.).

Increasing the flow rates of the main work processes is one of the promising ways to achieve the highest productivity of earthmoving machines. In this regard, the requirements of increasing the maneuverability and mobility of these machines while simultaneously increasing output, reducing their weight, and specific energy consumption of work processes leads to the widespread use of continuous transport with rotary machines of layered development. One of these new types of machines are excavating and transport machines with an inertial rotor of lower unloading, which can be widely used when performing large volumes of excavation, stripping and mining operations in the mining, reclamation and construction industries. The paper presents the results of studies of high-speed digging and suggests a method for determining the average energy intensity of soil transportation, and the proposed equations can be recommended for calculating the inertial rotor. The table of costs of specific energy intensity and productivity from the speed of rotation of the rotor at constant chip sizes is given.

This study presents the kinematic synthesis of planar mechanisms using precision point analysis for three, four, and five target positions. The research explores the application of graphical synthesis techniques to design mechanisms that accurately follow prescribed motion paths. Various configurations are examined, comparing their synthesized motion with theoretical precision points to evaluate the accuracy and feasibility of the proposed designs. Additionally, numerical optimization methods are considered to refine the results and improve motion fidelity. The study also extends the discussion to higher-order synthesis, incorporating additional precision points for improved accuracy in motion generation. The graphical results highlight the effectiveness of the synthesis approach, demonstrating its applicability to practical mechanism design. The findings contribute to the understanding of planar mechanism synthesis and provide insights into enhancing design methodologies for motion control applications. This paper presents GIM software, an educational and research software designed to facilitate the kinematic analysis of planar mechanisms. The software was developed to address the challenges students face in understanding kinematic theory and mechanism synthesis, providing an interactive and user-friendly platform for modeling and analyzing n-degree-of-freedom linkages.

This paper examines ways to improve the efficiency of the scraper’s operating process by refining the cutting system and bucket-filling technology. The objective of the study is to justify design and technological solutions that reduce digging resistance, ensure more uniform bucket filling, and increase technical productivity. The research included an analysis of existing cutting systems, the development of a combined design featuring two side cutting blades and a center adjustable cutting blade, the refinement of the calculation method for filling resistance, as well as laboratory and field experiments using physical models and a modernized DZ-77A scraper. It has been established that changing the geometry and cutting angles of the blades promotes the stepwise formation of chips and improves the distribution of soil in the bucket. Using the two-stage filling technology, the volume of soil collected increased by 17–19% depending on the soil type, and the technical productivity when excavating loam reached 67.97 m³/h compared to 58.32 m³/h using the traditional method, which corresponds to a 16.51% increase. The results obtained confirm the potential of improving the cutting system and the two-stage filling technology to increase the efficiency of scrapers.
