Abstract:
A presente invenção refere-se a um novo método para efetuar a imediata compensação lateral de máquinas agrícolas, do tipo colheitadeiras, as quais são particularmente providas de conjuntos de esteiras como meios de tração. O presente método compreende etapas configuradas para obter uma simplificação substancial na maneira de condução feita pelos operadores e, ao mesmo tempo, assegurar um controle eficiente do conjunto de tração, para evitar derrapagens que possam afetar a qualidade da colheita. Mais especificamente, o presente método de compensação lateral compreende as etapas de verificação da solicitação de aumento ou redução da compensação; confirmação do acionamento; envio de sinais de referência para a unidade de controle da máquina com o objetivo de incrementar ou reduzir a compensação e aguardar um período de tempo Δt1 para retornar para a etapa inicial para nova checagem. A presente invenção também se refere a uma máquina agrícola do tipo colheitadeira.
Abstract:
A grain quality sensor comprising a lens, a filter, a photosite array, an illumination source, and an electronics module, wherein the illumination source directs light containing a known set of wavelengths onto a crop sample, wherein the lens picks up light reflected by the crop sample and directs it into the filter, which allows light to pass into different parts of the photosite array such that certain locations on the photosite array only get certain frequencies of the reflected light, wherein the electronics module is electrically connected to the photosite array and capable of determining which parts of the photosite array received light and what frequency the light received was, wherein the electronics module can analyze the optical data received by the photosite array, and wherein the analysis of the optical data is used to determine the composition of different parts of the crop sample.
Abstract:
L'invention porte sur un système d'ajustement de la hauteur d'un outil agricole (0), comprenant un bras (1) apte à être commandé pour permettre d'élever et d'abaisser l'outil, un capteur de mesure de hauteur (E, R) monté sur le bras et positionné de manière à être au-devant de l'outil dans une direction de trajet d'un véhicule équipé du bras, et un calculateur configuré pour fournir une consigne de commande de la hauteur du bras à partir des mesures réalisées par le capteur, caractérisé en ce que le capteur est un appareil à rideau de lumière composé d'un émetteur (E) sous la forme d'une colonne de sources lumineuses (S1, S2, Sm) et d'un récepteur (R) sous la forme d'une colonne de photorécepteurs, l'émetteur et le récepteur étant montés sur le bras de manière à se faire face et à s'étendre selon leur direction longitudinale perpendiculairement au sol pour mesurer la hauteur de végétaux présents entre eux.
Abstract:
A material flow sensor for a harvesting machine comprising an acoustic chamber comprising an impact plate and a housing, microphone, a pneumatic impulse line connecting the housing and the microphone, and an electronics module, wherein the housing is shaped so as to direct sound waves created by crop matter striking the impact plate into the pneumatic impulse line, wherein the sound waves move through the pneumatic impulse line into the microphone, which detects the sound waves and converts them into an electrical signal that is a representation of the sound power derived from the sound waves, which in turn is a representation of the mass of the crop matter striking the material flow sensor.

An agricultural combine (1) comprising a residue spreading system (4) that is steerable to influence distribution (5) of the residue spreading system, wherein the combine is provided with a sensor (7) provided for emitting a wave signal through the residue when the combine is spreading the residue, and wherein the sensor measures reflections of the signal from a first zone (8) of the residue and from a second zone (9) of the residue, and wherein the spreading system is steered based on the reflections, wherein the wave signal has a wavelength that is larger than 0,001 mm and that is smaller than 50 mm.
Abstract:
A method implemented in an agricultural machine (10) harvesting alfalfa plants, the method (68) comprising: receiving, in real time, input corresponding to a plurality of sensed parameters corresponding to alfalfa plant height and cut alfalfa volume (70); associating the cut alfalfa volume to an alfalfa stem diameter (72); and automatically determining a feed quality value for the alfalfa plants based on the sensed alfalfa plant height and the alfalfa stem diameter (74).
Abstract:
The present invention is related to a combine harvester comprising a pair of track units or equivalent ground engaging means at the front of the harvester. The track units are suspended in the way known in the art, i.e. the frame of the units is pivotable about a centrally placed pivot axis, the axis dividing the track unit between a front and rear portion, so that the pivoting of the track unit results in upward and downward tilting of the front and rear portions. For each of the track units, the harvester comprises at least one variable length actuator mounted between the chassis of the harvester and the frame of the track unit, the actuator being mounted so that it is capable of actuating an upward and/or downward tilting of the front portion of the track unit. The actuator is operated to counteract an excessive downward and/or upward tilting of the front portion of the unit. The actuator may be operated by a control mechanism working on the basis of measurements performed by suitable sensor arrangements that monitor or predict the downward or upward tilting. The actuators may be part of a lifting system for the entire frame of the actuator. In the latter case, the cleaning arrangement of the harvester may be placed above the track units, the cleaning arrangement having a functional width that is larger than the distance between the track units.
Abstract:
In one embodiment, a system, comprising: a detachable implement (12) comprising a target area; and a machine (10) comprising: a portion configured to couple to the detachable implement in an area corresponding to the target area; and a control system (64) configured to: detect the target area; automatically cause the portion to align with the target area; and responsive to the alignment, cause automated coupling of the portion with the detachable implement in the area corresponding to the target area.
Abstract:
A control system and method for adjusting a rotational speed of a header on an agricultural vehicle based on ground speed of the agricultural vehicle. The header may include a plurality of cutters rotatably actuated with a header actuator. The control system may have a processor that compares a ground speed of the agricultural vehicle with a threshold ground speed. If the ground speed of the agricultural vehicle is below the threshold ground speed, the processor may command the header actuator to rotate the cutters at a constant predetermined rotational speed. If the ground speed of the agricultural vehicle is above the threshold ground speed, the processor may command the header actuator to increase rotational speed of the cutters in proportion to the ground speed of the agricultural vehicle.
