The article presents the results of research on the wear of belt conveyors’ elements made of various materials. For the purpose of the experiment, a test stand was built, reflecting the real working conditions of the conveyor belt, on which abrasive tests of samples made of appropriately selected materials and a control sample of steel were carried out. Obtained wear values indicated the most wear-resistant...
The paper presents quantitative results of mass wear of plough chisels working in soil made of various steel types and subjected to pad welding. The research was carried out in real field conditions on soils with similar physical and chemical parameters during routine field work in autumn. The scope of the research included the quantitative determination of wear values depending on the type of steel...
The use of 3D printing technology allows to make simple machine parts including agricultural machinery in home conditions using FDM printers. Printing technology can be used to produce machine components that are subject to accelerated wear or variable strains that damage them. It is an alternative to parts made of plastics whose cost is significant and the availability is limited. The article presents...
The paper presents the most frequently applied multibucket excavator solutions used in brown coal surface mining. The authors have analyzed the design of the excavator bucket individual components in terms of its wear during operation and the possibility of regeneration. The main aim of the performed analyses was to determine the costs of regeneration of the excavator buckets for selected multibucket...
Application of materials of adequate hardness and abrasion resistance is important from the point of view of the exploitation of agricultural and heavy-duty machinery, especially the components of those machines that work in the ground. Therefore, the main goal of the studies is to determine the mass loss of 7 and 8 mm thick samples made of Armox 600, Ramor 500 and S355 steel. The study was carried...
The main goal of the research was to design and build a prototype of device used for pneumatic transport, which will increase the difference of pressure in the pipeline and will increase velocity of the airflow during the transport of materials over different distances. During design process of the device using graphics software assumes that the system of separation of grain and air should be eliminated...
