BACKGROUND: Currently there is no simple and reliable algorithm of assessment pressure on soil for the harvesters presented market. Therefore, analysis methods in active standards used calculation propulsion as well development simplified acceptable manufacturing specialists method are relevant.
 AIMS: Simplification force action to wheels during operation cycle from beginning until end co...

Aiming at the common problems of high working resistance, low soil disturbance, and rates missed extraction in operation carrot combine harvesters, a high-efficiency drag-reducing bionic soil-loosening shovel was designed this study. The physical parameters carrots were measured, using badger claw toe as prototype. wing structures designed. Based on EDEM discrete element simulation technology, ...

As one of the core working parts a combine harvester, cleaning device directly affects operation performance whole machine. This is especially case on hilly and gently sloping terrain, which, due to uneven ground, causes harvester body incline material accumulates side, resulting in high loss rate. To solve this problem, self-leveling screen control system based fuzzy PID algorithm are develope...

This study investigated the status of mechanized power and self-propelled rice cultivation machinery in Guilan Province in northern Iran. The raw data was obtained from 2013 statistics of the Agricultural Jihad Organization of Guilan province. Power per unit of area, mechanization level, area per unit of self-propelled machinery, and mechanization requirement were calculated for eastern, wester...

in recent decades, canola has been considered as the most important oilseed. harvesting is the most major problem of canola cultivation, since canola pods are very sensitive to shocks and vibrations. large amount of produce will fall on the ground especially when the combine's head is not adjusted properly. when canola harvested with a combine, the losses may reach up to 50%. the yields can be ...

To improve the automation level and operation quality of China's beet harvester reduce loss due to damaged missed excavation, this study used a self-developed sugar combine field simulation experiment platform, based on single-factor bench test automatic row following system in early stage, taking hydraulic flow A, spring preload B, forward speed C which have significant influence performance i...
