Real-time measurement of cone index in a soil bin

Computers and Electronics in Agriculture, 1993
Abstract A personal computer-based measurement and control system for a hydraulic powered penetrometer developed as an integral part of a soil bin facility is described with respect to its construction, accuracy, repeatability and versatility. The system can, for example, measure and display cone index versus depth graphically in real time or at the ...

Computer instrumentation for the NSDL soil bin penetrometer car

Computers and Electronics in Agriculture, 1986
Abstract A microcomputer instrumentation system was developed for use with the National Soil Dynamics Laboratory (NSDL) soil bin penetrometer car. This system provided measurement of penetrometer force and depth as well as location on the soil bin, graphic display of penetrometer force vs. depth, and transmission of all data to the NSDL host computer.

Deformation and Failure in Wet Clay Soil: Part 2, Soil Bin Experiments

Journal of Agricultural Engineering Research, 1993
Abstract Tests of soil cutting by wide tines were conducted in wet clay soil. Force-displacement curves were obtained and the soil deformation patterns were observed and analysed with the help of a painted grid. The tine experiment showed that the soil deformation pattern depended on the tool rake angle (the angle between the tine face and the ...

Soil-Bin Performance of a Modified Bent Leg Plow

Applied Engineering in Agriculture, 2008
The present study was conducted to design and develop a new shape of bent leg plow (BL). The main difference between modified and conventional BL plows is the direction of angle between cutting blade and the line perpendicular to the plow shank. Soil-bin tests were conducted to study the performance of the modified plow as compared to the conventional ...

Evaluation of an On-the-go Soil Strength Profile Sensor Using Soil Bin and Field Data

2004, Ottawa, Canada August 1 - 4, 2004, 2004
An on-the-go soil strength profile sensor (SSPS) has been developed to measure the within-field spatial variability in soil strength at multiple depths up to 50 cm. In this paper, performance of the SSPS was evaluated using soil bin and field data. First, the SSPS was tested in a soil bin at different depths (10, 20, and 30 cm), forward speeds (from

Designing Better Transducers for Soil Bin Tests

1995
One of the most widely force transducers used in soil bin for cutting forces measurements is the well known extended octagonal ring dynamometer. This device, though originally developed mainly by empirical considerations [1], gives generally a satisfactory response to the demands imposed by static or quasi-static tests where a high degree of accuracy ...
