TECHNICAL SUPPORT OF FLAT PLOWING BY MOLDBOARD WORKING BODIES
The paper deals with a review of theoretical and experimental studies on the problems of substantiation the parameters of the plow bodies for rhomboid plowing, meeting the technological requirements of flat plowing with the lowest energy consumption and ensuring the enhancement of tillage machines performance and reduction of the plow metal-intensity. The results of studies conducted show that by changing the shape of the furrow layer cross section to the form of a rhomb it is possible to improve the process of the furrow slice turning. The main trends of improving the plow working bodies and the methods of designing their share-moldboard surfaces, as well as the works on the theory of plow working bodies’ interaction with the soil, have been analyzed. The necessity to develop the methods of designing the share-moldboard surfaces of the rhomb - like body, regulating the soil layer movement along the trajectory, which ensures minimal energy consumption, has been substantiated.
