abstract- noise is considered as one of the most debilitating conditions in farming operations. in this study, a number of factors affecting the noise generated by sampo 3065 combine harvesters were evaluated. factors were engine speed and gear ratio for combines with and without original cabins. a factorial experiment arranged as a completely randomized design with four replicates was used. re...

rice is a main food for iranian people and has an important role in providing food security. regarding the population growth, increase of rice production and reduction of losses have special importance in prevention of rice import. rice losses in the harvest stage are the highest through the whole production period of this crop and hence the reduction of these losses is necessary. provision of ...

two types of paddy combine harvester (head-feed and whole-crop) are commonly available in different widths in developed countries. the use of combine harvesters can greatly decrease labor costs and efficiency. combine harvesters have been introduced in several east asian countries (china, japan, south korea) to decrease costs, but their technical and economic performance has not yet been studie...

rice is one of the most important staple cereals‏ ‏in iran and has a main role in providing ‎the food ‎security. harvesting by hand postpone the rice harvesting stage, and facing late season ‎rainfall, and increase of yield losses during harvesting. to determine the most suitable ‎harvesting method in gilan, three different harvesting methods (by hand, harvester and ‎combine) were considered as...

Working on new equipments to increase agricultural productivity and safety, reducing human action hardness , Cemagref and Lasmea have developed an help guidance system for agricultural vehicles. The aim of this system is to help the operator to guide the machine in order to give more attention to the order task. To reach this goal, we use a visual perception of the environment because this sens...

The results of these studies showed that mechanical loader and combine harvester performance varied considerably depending on the type of machine, cane yield, and crop and field conditions. Instantaneous loading rates and mechanical harvesting pour rates varied between 60 and 100 tons per hour. Infield cane losses were significantly lower where the cane was manually cut and mechanically loaded ...

Using CAN (controller area network) field bus and iCAN protocol, an integrated measuring and controlling system for combine harvester is constructed in this paper. ARM is used as the processor of host computer. Lower computers are several measuring and controlling modules of combine harvester. Host computer communicates with lower computers through CAN bus. Information between measurement and c...
