Development and Evaluation of Laser-Controlled Chesil Plough CIGR Journal
Hegazy, Rashad Aziz; El-Sheikha, Ahmed.
The main purpose of this study is to improve the tillage operational efficiency of using chesil plough by transforming it into a more reliable system based on laser levelling technology. And thus, achieve quality of field sub-surface levelling in term of continues proper tilled layer and more stability of the soil tilled layer height along the whole field. The developed chesil plough chassis-attached laser control unit constructed by attaching levelling adjustment wheel system to chesil plough’ main frame and both coupled with the hydraulic system to facilitates the using of laser unit and to manage the receiver tower's up and down motion. Measured data of tilled layers elevations was collected after using laser-controlled chesil plough l and normal...

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...

Functional analysis in the evaluation of four concepts of planters Ciência Rural
Reis,Ângelo Vieira dos; Forcellini,Fernando Antônio.
The essential functions of a planter are to open the planting furrow, meter the seeds, deposit them in the furrow, cover them and compact the soil around them. The planter precision is affected, in some way, by each of those functions. Function analysis is a tool used in the conceptual phase of product design which allows an abstract formulation for the function of the technical system, thus making it very useful in product design and in the analysis of existing products. Therefore, the technique of function analysis makes it possible to identify, in the various concepts of planters sold in the Brazilian market, which function is not well implemented when considering precision planting of small grains, being this the main objective of this study. This...
