PALIČKA, M.: Anti Overload Equipment of the Plowing System. Ostrava: Department of Production Machines and Design - 340, Faculty of Engineering VŠB – Technical University of Ostrava, 2015. 76p. Diploma thesis, head: Kubín, T. This diploma thesis deals with the engineering design device against overload of plowing system. It is a hydro-pneumatic non-stop protection of plowing system for sided furrow ploughs. When plough body runs on an obstacle in soil, it moves upwards or sideways. After overcoming the obstacle, the body returns to the working position. The body is secured by a force generated by linear hydraulic motor connected to hydraulic accumulator, which is pressurized to operation pressure. Securing force, when the body is deflected from the working position, is controllable by changing the pressure in hydraulic circuit depending on conditions and soil type. The device is intended for ploughing in medium and heavy conditions with high incidence of stones.
