摘要： A sensor system for determining crop yield is disclosed. The sensor system comprises a mounting structure mounted to a housing of a grain elevator of an agricultural work machine and has at least one aperture formed therein. A fulcrum assembly is arranged on the mounting structure. A rocker arm is pivotal about a pivot axis of the fulcrum assembly and extends between a first end and a second end. An engagement member is coupled to the second end of the rocker arm and extends through the at least one aperture of the mounting structure. At least one gap distance sensor is mounted to the fulcrum assembly and is configured to detect an inclination of the rocker arm relative to the fulcrum assembly. A processing device is coupled to the gap distance sensor and is configured to correlate the detected inclination of the rocker arm to an applied force.

摘要： A sensing system (100) for obtaining a gradient of soil properties in real-time as a function of soil depth is disclosed herein. The sensing system includes a support structure (102) coupled to an agricultural implement and which is rotatable about a rotational axis relative to a frame of the agricultural implement. A sensor (106) is arranged on a surface of the support structure and configured to generate an output signal indicative of the measured soil property based on a sensed a capacitance change corresponding to a change in a dielectric property of a measured soil sample with which the sensor interacts. A measuring unit (108) is coupled to the at least one sensor and processes the output signal generated by the at least one sensor to generate a gradient profile of the soil properties in real-time as a function of one or more depths for display on a user interface.

摘要： Embodiments herein relate to a time domain depth sensor system (100) and method for determining a depth of a ground engaging device (220) in soil. The sensor system may include a signal transmission element (104) arranged on an outer periphery of a ground engaging device that is adapted to penetrate soil. The signal transmission element can be arranged to receive and transmit an electrical signal that is responsive to impedance discontinuities detected by a pulse detector (122). The pulse detector is configured to detect a first and a second reflected signal corresponding to a sensed impedance discontinuities at a first and a second soil location. An electronic data processor (132) is communicatively coupled the pulse detector and is configured to determine the depth of the ground engaging device in the soil based on a difference between a first time of propagation of the first reflected signal and a second time of propagation of the second reflected signal.
