EXPERIMENTAL RESULTS ON THE EFFECT OF PRESSURE SPRINGS GENERATING THE PRESSURE FORCE APPLIED TO THE SUPPORT DISC INSTALLED ON A DISC PLOUGH ON ITS OPERATING PERFORMANCE

This paper presents the results of experimental studies on the influence of the pressure force applied to the support disc on the operating performance of a disc plough. The experiments showed that when the pressure force applied to the support disc was 500 kN, the supporting force was insufficient, which caused the actual working width of the plough to exceed the design working width by 6.3 and 8.2 cm during mouldboard-type ploughing. Under the same pressure force of 500 kN, the use of pressure springs led to lateral deviation of the plough during operation. When the pressure force applied to the support disc was increased to 600-700 kN, the plough operated without lateral deviation; as a result, its actual working width was almost identical to the design working width.
