摘要： A row unit for a seeding machine includes a seed reservoir and a seed meter assembly having a metering member with a seed side facing the seed reservoir and a non-seed side opposite the seed side. The metering member is operable to selectively move seeds from the seed reservoir. A pump provides a pressure differential between the seed side and the non-seed side for adhering the seeds to the metering member. A conveyor has an inlet for receiving the seeds and an outlet configured to discharge the seeds from the seeding machine. The conveyor includes a belt movable from the inlet to the outlet. A pneumatic seed displacer includes a nozzle disposed adjacent the metering member for concentrating air. The nozzle is configured to eject the air towards the metering member for directing the seeds from the metering member to the conveyor.

摘要： A product on demand nozzle assembly includes a chamber at least partially defined by an external wall and an array of vertically spaced nozzles. Each nozzle has an air inlet, an air and entrained product outlet extending from the external wall, and an entrainment zone between the air inlet and the air and entrained product outlet to receive a product therein to be distributed.

摘要： A row unit for a seeding machine includes a ground view sensor coupled to the frame. The ground view sensor is operable to sense the furrow and generate depth signals corresponding to actual sensed depth of the furrow. The row unit also includes a controller configured to receive the signals, and a downforce adjustment mechanism coupled to the frame and to the controller. The controller is configured to activate the downforce adjustment mechanism to adjust a downforce on the frame based on the signals received by the controller.

摘要： A row unit for a work vehicle includes a row unit frame with a closer frame. The closer frame defines a longitudinal axis and a transverse axis. The closer frame is supported for rotational movement about a substantially vertical steering axis to vary a turning angle between the longitudinal axis the vehicle longitudinal axis. The row unit includes a closer implement assembly with first and second closer implements and a walking beam construction. The first and second closer implements are attached to opposite areas of the walking beam construction. The walking beam construction is rotationally attached to the closer frame to support rotation of the closer implement assembly about the transverse axis. The first and second closer implements are configured to move ground material into a ground opening from opposites sides as the work vehicle moves across the field.

摘要： An equipment control system detects a physical position of a first vehicle, carrying a material to deliver, relative to a second vehicle. A physical position of a conveyor is controlled, relative to an outlet opening defined on the first vehicle and an inlet opening defined on the second vehicle. The material is then illustratively automatically conveyed from the first vehicle to the second vehicle.

摘要： A seeding machine includes a main frame, and a row unit coupled to the main frame. The row unit has a row unit frame, a gauge wheel coupled to the row unit frame, and a furrow opener coupled to the row unit frame, the furrow opener having a stationary or rotating surface that contacts and moves soil. The row unit also includes a furrow closer, the furrow closer having a stationary or rotating surface that contacts and presses soil. The seeding machine also includes a downforce adjustment system for adjusting an amount of downforce applied to the row unit, the downforce adjustment system including a moisture sensor, a controller configured to receive a signal from the moisture sensor, and an actuator configured to change the amount of downforce applied to the row unit based on the signal received by the controller.

摘要： A product distribution system includes a product on demand pick-up assembly including a hopper. The hopper is configured such that an air stream flowing into the pick-up assembly entrains product therein and conveys product downstream through a plurality of conduits. The product distribution system further includes a container for storing product prior to delivery of product to the pick-up assembly and a meter and conveyor assembly configured to move product from the container to the pick-up assembly hopper such that an amount of product greater than a predetermined quantity is maintained in the pick-up assembly hopper during operation of the system.
