Descripción: COMPENDIOPara determinar y eficientar los requerimientos de energía en la labranzavertical en esta investigación se desarrolló y evaluó un transductor integralpara la medición de la fuerza de tiro en un prototipo de labranza vertical conarreglos de hasta seis cinceles con y sin alas expansoras. La calibración delos octagonales bajo condiciones de laboratorio mostraron un coeficiente decorrelación superior al 99% en la eficiencia del monitoreo y detección de lasfuerzas. Se detectó en laboratorio con el uso del transductor integral unmomento de fuerza resultante con una proporción de 1:1.01 y de 1:1.3cuando las cargas se localizaron a 0.59 y 0.79 m de profundidad conrespecto al centro de los octagonales inferiores. En las evaluaciones encampo del transductor integral en conjunto con el dinamómetro de tiro, lasmagnitudes de las fuerzas presentaron la misma proporción de 1:1.3obtenidas en laboratorio, lo que valida la alta confiabilidad del equipo. De laspruebas realizadas en el sitio experimental de Navidad, propiedad de laUAAAN, de los arreglos del primer bloque en la que se compara un cincelcon tres diferentes tamaños de alas contra la prueba de dos cincelesfrontales a 0.20 m de profundidad no hubo diferencias estadísticassignificativas en la resistencia específica del suelo con un promedio de 83kN/m2.
An integral force transducer was designed to determine the energy requirements on vertical tillage with a six arrays chisel winged tine implement. In laboratory conditions a correlation coefficient greater that 99% force monitoring was found during the calibration of three octagonal ring transducers. Using the integrated force transducer a resultant moment was detected, the ratio moment was 1:1.01 and 1:1.3 when loads located to 0.59 and 0.79 m of depth about center of the octagonal rings. In field evaluation of the integral transducer overall dynamometer compare with de axial dynamometer, found same ratio of 1:13, the same obtained in laboratory conditions, demonstrated the reliability of the integral force transducer. The field experimental trials were conducted in UAAAN Navidad experimental station. For the evaluation purpose the set of experiments were divided in three blocks, the first group for specific soil resistance does not exist significant differences, comparing one winged chisel tines versus two shallow tines, were not found at 0.20 m depths with a mean 83 kN/m2. Using winged x chisel tines (SW, MW and WL) proportionally improved by 30% versus one chisel tines without wings from 121 to 82 t kN/m2, respectively. For the second block, the arrangement of two front shallow tines at 0.20m depth combined with a single winged chisel tine at 0.30 m depth (MW) contributes significantly to reduce the specific soil resistance compared with the arrangement of two front shallow tines at 0.20 m depths and rear chisel tines without wings, the specific resistance varied of 73 to 84 kN/m2 respectively. The Evaluation test of third block, two rear tines (SW, MW and WL) at 1.20 m spacing and 0.30 m depth, the specific soil resistance decreased significantly using (LW) winged tine versus other (SW and MW) from 84 to 100 kN/m2, respectively.
