摘要： In one aspect, a system for rephasing fluid-driven actuators includes a plurality of fluid-driven actuators fluidly coupled together in series. A controller is configured to monitor a position differential existing between current positions of rods of the actuators relative to a differential threshold based on sensor measurements. The actuators are out-of-phase when the monitored differential exceeds the threshold. The controller is also configured to initiate a flow of fluid to the actuators to rephase the actuators when the monitored differential exceeds the threshold. The controller is further be configured to continue to monitor the differential following initiation of the flow of fluid to the actuators. Additionally, the controller is configured to implement a control action associated with terminating the rephasing of the actuators when the monitored differential remains constant after a first time period has elapsed following initiation of the flow of fluid.

摘要： An agricultural air seeder planting unit incorporates control valves that split flow and change direction from supply to distribution hoses. The flow area of the control valves is automatically adjusted pneumatically by movement of a piston in response to total pressure to provide a uniform velocity flow from each of the control valves.

摘要： The present disclosure provides systems and methods that measure soil roughness in a field from imagery of the field. In particular, the present subject matter is directed to systems and methods that include or otherwise leverage a machine-learned clod detection model to determine a soil roughness value for a portion of a field based at least in part on imagery of such portion of the field captured by an imaging device. For example, the imaging device can be a camera positioned in a downward-facing direction and physically coupled to a work vehicle or an implement towed by the work vehicle through the field.

摘要： A metering system for an agricultural vehicle includes meter rollers, each including protrusions driving flow of flowable particulate material in response to rotation of the meter roller. The metering system also includes a drive shaft driven in rotation and includes transmission assemblies that each correspond to a respective meter roller. Each transmission assembly includes a respective moveable gear actuatable to engage each of a plurality of gears to establish a respective gear ratio corresponding to one of a plurality of different speeds of the respective meter roller relative to the drive shaft.

摘要： A product distribution control system for an agricultural system includes a controller having a memory and a processor. The controller is configured to receive a first signal indicative of a prescription map. The controller is further configured to determine a first parameter associated with operation of an air cart of the agricultural system based at least in part on the prescription map. The controller is further configured to determine at least one of a second parameter associated with operation of a work vehicle of the agricultural system based at least in part on the prescription map, and a third parameter associated with an implement of the agricultural system based at least in part on the prescription map, wherein the implement includes one or more row units. The controller is further configured to output, in response to determining the first parameter, a second signal indicative of an instruction to control a first element of the air cart based at least in part on the first parameter, output, in response to determining the second parameter, a third signal indicative of an instruction to control a second element of the work vehicle based at least in part on the second parameter, and output, in response to determining the third parameter, a fourth signal indicative of an instruction to control a third element of the implement based at least in part on the third parameter.

摘要： In one aspect a system for controlling the operation of an agricultural implement may include a vehicle-based controller configured to control an operation of a valve provided in operative association with a work vehicle, with the valve being configured to control a fluid flow to a plurality of fluid conduits. The system may also include an agricultural implement configured to be towed by the work vehicle. The implement may include a user interface having a first input device configured to receive an input associated with a selected fluid conduit of the plurality of fluid conduits. Furthermore, implement may include an implement-based controller supported on the implement and communicatively coupled to the user interface. The implement-based controller may be configured to initiate control of the operation of the valve based on the input received from the user interface in a manner that provides the fluid flow to the selected fluid conduit.

摘要： The present invention is directed to an applicator having an agricultural product mechanical and/or pneumatic conveying system which transfers particulate material from one or more source containers to application equipment on demand, and meters the material at the application equipment. The conveying system includes a static distributor interconnecting the supply lines of the conveying system with the distribution lines connected to the individual nozzles. The static distributor includes internal structures that effectively divert the incoming particulate material evenly across the interior of the static distributor such that the particulate material is evenly distributed into each of the distribution lines. The static distributor accomplishes this without the need for any moving parts or control systems/devices. In addition, damage done to the particulate material flowing through the distributor is not high, and the operation of the distributor creates a lower pressure drop across the distributor than prior art vertical distributors.

摘要： In one aspect, a system for removing blockages present within a delivery conduit of a seeder may include a plurality of delivery conduits, a plurality of flow blocking devices, and a plurality of blockage sensors. A controller may be configured to determine when a blockage is present within a first delivery conduit of the plurality of delivery conduits based on measurement signals received from the plurality of blockage sensors. The controller may be further configured to control the flow blocking devices to occlude the flow of air through the other delivery conduits of the plurality of delivery conduits such that an air pressure in the first delivery conduit is increased.

摘要： A seed planting unit of an agricultural implement may include a wheel support arm having an upper portion and a lower portion, the upper portion defining a depth adjustment slot. A wheel may be rotatably supported by the lower portion of the wheel support arm, the wheel configured to contact the soil surface to define a penetration depth setting for the ground engaging tool relative to the soil surface. A depth adjustment lever is selectively movable relative to the wheel support arm to vary the penetration depth setting for the ground engaging tool. The lever may include a guide pin that is configured to be received within the depth adjustment slot, the guide pin configured to move within the depth adjustment slot as the depth adjustment lever is moved relative to the wheel support arm to adjust a vertical position of the wheel relative to the ground engaging tool.
