An agricultural implement guidance control system has a wand sensor housing which contains a vertical shaft attached to the wand bracket and thus to the sensing wands. Affixed to the shaft is a photoelectric light source which projects a beam of light at a pair of photoelectric sensors. The photoelecltric sensors are mounted on a printed circuit board which is mounted to a slide plate. The slide plate is supported by slide supports and the slide supports have grooves in which the edges of the slide plates are positioned. The slide plate is able to slide left or right inside the grooves. An adjustment screw threadably engages a flange on the slide plate. The rotation of the adjustment screw causes the adjustable positioning of the slide plate to the left or right depending upon the rotation of the screw. Calibration of the guidance system with respect to the position of the sensing wands is accomplished by selective rotation of the adjustment screw.
An agricultural implement guidance system comprising a sensing means for sensing the position of plants or other ground reference indicia, a position indication means for indicating the position of said sensing means relative to an implement on which said sensing means is mounted, a receiving means for receiving a signal from said position indication means in accordance with the relative position therebetween, and an adjustment means for adjusting the relative position of said receiving means or said position indication means with respect to the other, said adjustment means including a rotatable threaded drive element which effects such relative positioning adjustment movements during the rotation of said element.
An agricultural implement guidance system comprising a sensing means for sensing the position of plant or other ground reference indicia, a photoelectric light source which emits a beam of light, means for moving said light source to adjust the position of aid beam in accordance with movement of aid sensing means during normal operation, a photoelectric sensor for receiving the beam of light from said photoelectric light source, and an adjustment means including a positive drive for calibration adjustment of the relative position between said photoelectric sensor means and said photoelectric light source.
An adjustment mechanism for an agricultural implement guidance system which system has a photoelectric light source which emits a beam of light towards a photoelectric sensor, means mounting said light source and said photoelectric sensor for movement of one relative to the other during normal operation of said guidance system to generate output signals for guidance control of said implement, and calibration means comprising a screw element and a complimentary threaded driving element which are attached to one of said
An agricultural implement guidance system comprising at least one sensing wand for sensing the position of plants or other ground reference indicia, a photoelectric light source which emits a beam of light for indicating the position of the sensing wand, at least one photoelectric sensor for receiving a signal from the photoelectric light source in accordance with the relative position therebetween, and an adjustment screw which is attached to said photoelectric sensor whereby rotation of said screw provides a means for adjustment of the position of said photoelectric sensor relative to said wand.
An agricultural implement comprising an implement frame for supporting the implement tools or units, at least one sensing wand for sensing the position of plants or other ground reference indicia, a photoelectric light source which emits a beam of light for indicating the position of the sensing wand, at least one photoelectric sensor for receiving a signal from the photoelectric light source in accordance with the relative position therebetween, an adjustment screw which is attached to said photoelectric sensor whereby rotation of said screw provides a means for adjustment of the position of said photoelectric sensor relative to said wand, and a support structure for supporting said sensing wand, said photoelectric light source, said photoelectric sensor, and said adjustment screw.
An agricultural implement guidance system comprising a sensing means for sensing the position of plant or other ground reference indicia, a photoelectric light source which emits a beam of light, means for moving said light source to adjust the position of said beam in accordance with movement of said sensing means during normal operation, a photoelectric sensor for receiving the beam of light from said photoelectric light source, and a calibration screw means, attached to said photoelectric sensor, for calibration adjustment of the position of said photoelectric sensor means with respect to said photoelectric light source.
