摘要： A direct drive electric seed metering system is provided for use with a row crop planter or seed planter that intakes a volume of multiple seeds from a seed hopper, draws individual seeds from the volume of multiple seeds and discharges them into a seed furrow formed in an agricultural field. The direct drive electric seed metering system includes a meter assembly having a meter housing and a seed plate rotatably mounted concentrically in the housing for singulating the seeds. A direct drive mechanism is mounted to the meter assembly for interfacing and driving the seed plate at an angular velocity which corresponds to the travel velocity of the seed planter. A single seed planter can have multiple direct drive electric seed metering systems, and each of the multiple direct drive electric seed metering systems preferably has its own prime mover to effectuate driving the seed plate.

摘要： An agricultural material metering system includes a metering member, a hydraulically driven actuator, a pump, a rotatable ground driven member, a variable drive control and an actuator coupled to the variable drive control. The metering member is configured to meter agricultural material upon being driven. The hydraulically driven actuator is coupled to the metering member to drive the metering member. The variable drive control is coupled between an inlet of the pump and the metering member and is configured for actuation between a first position in which the hydraulically driven actuator drives the metering member at a first rate and a second position in which the hydraulically driven actuator drives the metering member at a second rate. The rotatable ground driven member is coupled to the pump and drives the pump when rotating. The pump is coupled to the hydraulically driven actuator and displaces fluid upon being driven to drive the hydraulically driven actuator. The actuator coupled to the variable drive control is configured to actuate the variable drive control between the first and second positions to vary the rate in which materials metered by the metering member. One exemplary embodiment, the variable drive control is incorporated into the pump, wherein the pump comprises a variable displacement pump. In another embodiment, the variable drive control is incorporated into the hydraulically driven actuator such that hydraulically driven actuator comprises a variable displacement hydraulic motor.

摘要： A row unit for a seed-planting implement includes a frame, a gauge wheel arm pivotably coupled to the frame and a gauge wheel rotatably coupled to the gauge wheel arm. Additionally, the row unit includes a wobble bracket configured to engage the gauge wheel arm and a linkage arm coupled to the wobble bracket. Moreover, the row unit includes an actuator, a gearbox coupled to the actuator, a threaded shaft coupled to the gearbox, and a handle coupled to the threaded shaft. In addition, the row unit includes an actuation assembly such that the actuation assembly transmits rotation of the threaded shaft into linear motion of the linkage arm. The actuation assembly includes a hook arm having a first end forming a hook that directly couples to the linkage arm. Furthermore, the actuation assembly includes a collar threadingly coupled to the threaded shaft.

摘要： An agricultural system includes a controller comprising a memory and a processor. The controller is configured to receive a sensor signal, determine a current flow based on the sensor signal, determine whether the current flow exceeds a current threshold for a time threshold, and operate a drive system of the agricultural system in an alternative operation instead of a normal operation in response to determining the current flow exceeds the current threshold for the time threshold.
