Instrumentation System for a Model Laboratory Soil Bin

FUOYE Journal of Engineering and Technology, 2023
Tool development and prime mover selection for optimum tillage operation require both the knowledge of soil and tillage tool interaction dynamics which is a function of some system parameters. The actual value of these parameters can only be determined either from field or soil bin experiment via appropriate instrumentation systems.

Predicting the wheel rolling resistance regarding important motion parameters using the artificial neural network [PDF]

Journal of Agricultural Machinery, 2016
Introduction: Rolling resistance is one of the most substantial energy losses when the wheel moves on soft soil. Rolling resistance value optimization will help to improve energy efficiency.

Ação de rodas compactadoras de semeadoras submetidas a cargas verticais na deformação do solo Effect of submitted seeders press wheels under the vertical loads in soil physical deformation

Ciência e Agrotecnologia, 2005
Uma semeadura bem realizada é fundamental para o sucesso de implantação de uma cultura e as rodas compactadoras utilizadas nessa operação devem ser capazes de melhorar o contato solo-semente para promover boa emergência das plântulas.

Discrete Element Modelling of Soil Compaction of a Press-Wheel

AgriEngineering, 2021
Press-wheels are wheels designed to compact the soil above seeds in the “seed cover” region. Soil compaction, produced by the press-wheels of seeders, affects seedling emergence and early plant growth.

VIII.—The Soils and Vegetation of the Bin and Clashindarroch Forests

Transactions of the Royal Society of Edinburgh, 1941
The Bin and Clashindarroch Forests lie some 40 miles to the north-west of Aberdeen. Clashindarroch Forest, the larger of the two, stretches from the Rhynie-Cabrach road in the south almost to the Huntly–Glass road in the north. The Bogie valley in the east forms another rough boundary for the hill mass that the forest occupies.

Effect of soil particle-size distribution (PSD) on soil-subsoiler interactions in the discrete element model

Spanish Journal of Agricultural Research, 2021
Aim of study: This work investigated the significance and mechanism for the effect of particle-size distribution (PSD) under different nominal radii using the discrete element method (DEM) and validated using the laboratory soil-bin results to accurately

Design and Construction of a Disc Harrow Carrier Chassis in a Soil Bin and Measuring Its Draft Force [PDF]

Journal of Agricultural Machinery
IntroductionOne of the most important parts of agricultural operations is tillage, which accounts for about 60% of the total energy consumed. Therefore, reducing tillage energy demand by lowering the number of passes through the development of cost ...
