TEMPERATURE OF PLOUGHSHARE MATERIAL IN THE COURSE OF PLOUGHING
Journal Title: Tribologia - Year 2016, Vol 266, Issue 2
Abstract
The change of temperature of subsurface layer material of ploughshare, occurring in the course of fine sandy loam (8% moisture and temperature 15.3°C) cultivation, done with bed making plough, was determined. Measuring system with 10 temperature sensors built in the ploughshare material was used in the research. Temperature value was registered with frequency of 1 Hz. The increase of temperature of subsurface layer of ploughshare blade material used in soil was fast – time of temperature stabilization was, depending on location the place of measuring from 17 to 43 s. In the course of ploughing the most heated was the initial area of the attack of landslide part of ploughshare blade and area adjacent to field edge – from 42.6 to 47.3°C. The temperature of material of trapezoid part of ploughshare blade was 26.6 to 29.7°C. In the conditions of the conducted measurements the rate of cooling of the subsurface layer of ploughshare blade material as the result of its cooling was 0.007 to 0.028°C·s-1 while plough was not working, however while making U-turns was from 3 to 7 times higher. In the places where the material of ploughshare blade was more heated the rate of cooling was of course higher. Faster cooling of ploughshare blade during U-turns was probably the result of intensified cooling induced by plough movement in the air.<br/><br/>
