design, construction and field evaluation of a tractor-mounted penetrometer
soil compaction is an important aspect of agriculture and different methods are available to measure this parameter. one method is called the cone index; measuring the force required per unit area for penetration of a standard steel cone into the ground. cone penetrometers are used for cone index measurement. in this study, a tractor mounted, hydraulically-operated penetrometer was designed, bu...
متن کاملdesign, development and evaluation of electronic control valve for hydraulic pump of mf 285 tractor
the depth control systems used in iranian tractors are mechanical and they produce variable tillage depth in uneven field surface. in this research a rotary type electronic control valve was designed and constructed. by using this valve, electro-hydraulic tillage depth control system was developed and installed on the tractor. the control system was composed of: a depth sensor, a programmable l...
متن کاملdesign, fabrication and evaluation of a tractor-mounted soil cone penetrometer with multiple probes
soil compaction is a major problem in many parts of the world. the determination of soil compaction profiles requires fast sampling systems to keep pace with the change in soil moisture condition over time. soil cone penetrometers are commonly used for this purpose. a tractor-mounted soil cone penetrometer was designed and fabricated with multiple probes and the ability to determine cone index ...
متن کاملdesign, fabrication and evaluation of a tractor mounted digital cone penetrometer
for a determination of soil characteristics one should have access to instruments that can measure these characteristics, including: soil penetration resistance with high accuracy. one of the accurate instruments commonly employed in soil penetration determinations is cone penetrometer. this apparatus, by measuring soil cone index at different soil depths can provide useful about information ab...
