HARVESTER STABILITY MONITORING AND CONTROL
A controller for a harvester receives a speed of the harvester, the pitch, the yaw and the roll of the vehicle body, compares the sensed yaw, pitch and roll of the vehicle body to respective acceptable yaw, pitch and roll ranges. The controller also receives a conveyor position respect to the vehicle body, compares the conveyor position to an acceptable range of conveyor positions, calculates a center of gravity of the harvester based upon the yaw, pitch, roll and conveyor position, and compares the speed of the harvester to an acceptable range of speeds based upon the calculated center of gravity of the harvester. The controller also sends a signal to move the conveyor with respect to the vehicle body, alert the user to move the conveyor with respect to the vehicle body, reduce the speed of the harvester, or alert the user to reduce the speed of the harvester.
SENSOR ARRANGEMENT FOR AN AGRICULTURAL VEHICLE
A sensor arrangement for an agricultural vehicle includes a first electro-optical sensor including a first field of view having an optical axis, and a second electro-optical sensor including a second field of view having an optical axis. The first and second sensors are spaced apart from one another and oriented such that the optical axes of the two sensors intersect at a distance from the two sensors.
Speed Control Method and System for Harvester
A method of autonomously controlling the ground speed of a harvester, such as a self-propelled or towed wind rower, uses both the engine speed and the header speed as control parameters to increase or decrease the ground speed as necessary to maintain efficient harvester operation over varying terrain and crop conditions. A control system includes a controller which receives signals from sensors indicative of engine speed, header speed and harvester ground speed and uses actuators to control the header speed, engine speed and harvester ground speed. An operator interface permits an operator to engage or disengage the autonomous mode of control system operation, as well as to directly control the harvester.
Updating execution of tasks of an agricultural prescription
A method begins by a computing device allocating a plurality of tasks of an agricultural prescription for a farming geographic area to a fleet of farming equipment. While executing tasks of the plurality of tasks, the method continues with at least some of the fleet of farming equipment collecting task execution data. Based on the task execution data, the method continues with the computing device updating at least one of the agricultural prescription, the plurality of tasks, and the allocation of at least one task of the plurality of tasks.
Harvester
A harvester capable of autonomous travel in a field includes: a harvesting unit that harvests a crop from the field; a conveyance device that conveys, toward the rear of a harvester body, a whole culm of the harvested crop harvested by the harvesting unit; a detection sensor that detects a drive speed of the conveyance device; and a clog determining unit that determines a clog of the harvested crop in the conveyance device on the basis of the drive speed. The clog determining unit outputs a vehicle stop command that stops the harvester body when the drive speed becomes lower than a pre-set first threshold during the autonomous travel.
Drive System for a Harvester
A harvester comprising: a drive engine connected via a first drive train to ground engagement equipment of the harvester and via a second drive train to crop processing equipment of the harvester; an actuator configured to adjust the transmission ratio of the first drive train to control the propulsion speed of the harvester; and a controller configured to receive setpoint and actual values dependent on the crop throughput of the harvester, the controller configured to calculate an acceleration signal based on the setpoint and actual values, the acceleration signal representing an acceleration of the harvester suitable for minimizing the difference between the setpoint and actual values, and to determine a control signal for controlling the actuator based on the acceleration signal.
GANG ARM GAUGE WHEEL HEIGHT CONTROL FOR CROP HARVESTING DEVICE
A harvesting head for an agricultural harvester including a center frame section that is pivotally coupled to each of a left frame section and a right frame section. The elevation or height of the center frame section is determined by setting a height of the inner gauge wheels of the left and right frame sections. A gauge assembly for each of the left and right frame sections includes a linking member that spans between and operatively connects to outer and inner gauge wheels. The gauge assemblies are operably connected to the left and right frame sections to adjust an elevation of the outer and inner gauge wheels relative to the linking member to thereby adjust the elevation or height of the frame section when actuated by an actuation mechanism.
AI-optimized harvester configured to maximize yield and minimize impurities
Systems and methods are disclosed herein for detecting impurities of harvested plants in a receptacle of a harvester. In an embodiment, a harvester controller receives, from a camera facing the contents of the receptacle, an image of the contents. The harvester controller applies the image as input to a machine learning model. The harvester controller receives, as output from the machine learning model, an identification of an impurity of the harvested plants. The harvester controller transmits a control signal based on the impurity.
Monitoring device for monitoring crop yield
A monitoring device for monitoring crop yield is disclosed. The monitoring device is mounted to a housing of a grain elevator of an agricultural work machine proximate a crop conveyor assembly arranged in the housing and has at least one aperture formed therein. A material engagement member is arranged on the mounting structure and is pivotal with respect to the mounting structure about a pivot point. The material engagement member can comprise first end and a second end opposite of the first end. At least one rotational sensor is arranged in the monitoring device and is configured to detect spatial movement or position of the material engagement member. A processing device is coupled to the at least one rotational sensor and is configured to determine an aggregate crop yield based on the detected rotational magnitude of the displacement of the first end or second end.
Control method and apparatus for a rotor cage with actuated cage vanes in a harvester
A method for controlling crop material speed through a rotor/cage assembly of an agricultural combine. The method includes the steps of monitoring a grain loss of the combine and adjusting an orientation of a vane coupled to the cage responsive to the grain loss, a cleaning system load and/or a straw length.
