In the paper, the necessity of root stubble harvesting and recycling was put forward from the perspective of biomass energy utilization. To accomplish mechanized harvesting on root stubble, a rotary digging machine was designed based on parametric modeling software Solidworks. Firstly, parts were built under entity modeling module, and then assembled to 4 main mechanisms in assembling environme...

This paper concerns the analysis of the relationship between the threshing process in an axial flow harvesting machine and its vibro-acoustic behaviour. Several indoor and outdoor measurements are performed in various operational conditions in order to evaluate their influence on the vibration response of the threshing unit. The test results have been used to identify how the vibration and soun...

We have proposed and successfully demonstrated a novel approach to direct conversion of mechanical energy into electrical energy using microfluidics. The method combines previously demonstrated reverse electrowetting on dielectric (REWOD) phenomenon with the fast self-oscillating process of bubble growth and collapse. Fast bubble dynamics, used in conjunction with REWOD, provides a possibility ...

The applications for forest trees in computer graphics are varied, e.g.: children’s movies (e.g. Barnard, 2000), influencing opinion on extractive forestry (e.g. Bishop et al. 2003), harvesting machine simulators (CMLabs, circa 2003), immersive virtual reality (Gigliotti, 2002), games (e.g. Szijártó & Koloszár, 2003), and ecological studies (e.g. Dzierzon et al. 2003). The present work was foun...

Machine harvesting is an essential step of crop production, considering a dynamic operation, and subject to losses due several factors that affect its quality. The objective this study was evaluate the quality mechanized peanut pickers in three soil tillage operations using Statistical Quality Control (SQC) tools. We conducted experiments field located at 21°20′23″ S 47°54′06″ W Brazilian farme...

assessment and management of the environmental impacts of forest harvesting operations have become increasingly critical factors in practicing commercial forestry. this study investigated soil disturbance from a forest logging system operation on an 8-hectare mixed broadleaved stand in compartment no. 309 in gorazbon district in kheyrud educational and research forest. the objective of this stu...
