Design a capacitive sensor for rapid monitoring of seed rate of sugarcane planter CIGR Journal
Taghinezhad, Javad; Alimardani, Reza; Jafary, Ali.
A capacitive sensor method for measuring billet spacing uniformity with sugarcane (Saccharum officinarm L.) billet planter is investigated in this paper.  Therefore, an electronic device based on capacitive sensor was designed and developed to predict the planting spacing of sugarcane billets.  It consisted of four components: a rectangular parallel plate capacitor, electronic circuitry, microcontroller, and display unit.  Accordingly, a prototype of the precision metering device for sugarcane billets was developed.  After calibrating the monitoring system, the results were verified with calibrated curve by means of linear regression and paired T-test.  The performance of the device, including quality of feed index (QFI), multiple index and miss index was...

Models of mechanical cutting parameters in terms of moisture content and cross section area of sugarcane stalks CIGR Journal
Taghinezhad, Javad; Alimardani, Reza; Jafary, Ali.
The objective of this study was to find optimizing moisture content and cutting area of sugarcane stalk cutting parameters using multiple regressions and to verify the optimum levels of the variables.  The effect of moisture content and cutting section area on mechanical cutting properties of sugarcane stalks was studied using a linear blade cutting and UTM (Universal Testing Machine) size reduction device.  Data obtained in the laboratory were divided into four different groups in order to determine the peak force, cutting energy, ultimate stress and specific energy.  Additional criterions were also proposed and used as an indicator of the cutting performance.  These were the marginal cutting parameter (MCP) and return to scale (RTS).  The data obtained...

Development and performance simulation of a novel helical manure distributer machine CIGR Journal
taghizadeh tameh, jalil; Jafary, Ali; mousazadeh, hossein; tarabi, nazilla.
Organic manures play an important role in improvement of soil fertility, increase of crop yield and quality. Among these, the use of advantages of manures depends on method of spreading. Unsuitable method in spreading manure caused decreased crop production. Therefore in this study, a novel helical manure distributer machine was developed that capable to speared manure with maximum distribution width at different moisture of manure. The machine performance was modeled as well. This machine consisted of two screw conveyors (auger) on the bottom of hopper, grips, two drums, meshing plate and other component. Effect of speed of drum and mass of particle of manure on distribution width were considered. The power requirement of auger was calculated in different...
