Energy Evaluation of Tillage Tools Using Soil Bin

SAE Technical Paper Series, 1991
<div class="htmlview paragraph">Tillage is an importantcomponent of crop production system and may be defined as any mechanical manipulation of soil to improve its appearance and physical condition for crop production. The factors affecting the energy requirement by a tillage tools include initial soil conditions, tool shape, and manner of tool ...

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.

Soil-Blade Interaction of a Rotary Tiller: Soil Bin Evaluation

International Journal of Sustainable Agricultural Research, 2014
In this paper soil-blade investigation of a rotary tiller in a controlled soil bin is presented. Among the soil cutting agricultural tools currently used, the rotary tiller is one of the most promising equipment, saving operating time and labor. In a rotary tiller working tool is always a blade.

An Explosive Subsoiler for the Improvement of Meadow Soil, Part 2: Soil Bin Experiments

Journal of Agricultural Engineering Research, 2000
Abstract An explosive subsoiler was envisaged and designed to achieve greater soil rupture volume and longer sustainability of drainage for the improvement of meadow soil. In this paper, the results are presented from soil bin experiments with the explosive subsoiler, that were conducted in Japan prior to field experiments in China, to investigate ...

Innovative Design Features of A Soil Bin to Facilitate Research on Soil-Tool Interaction

2002 Chicago, IL July 28-31, 2002, 2002
A soil bin test facility has been designed to study on soil-tool interaction. It features a 20-m long by 2.44-m wide by 1-m deep bin, which supports eight segmented soil boxes. Soil conditions can be changed by inserting replacement soil box. The bin can be inclined up to the maximum slope grade of 20%.

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 ...

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 ...
