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： A seeding machine includes a seed metering system and a seed delivery system in communication with the seed metering system. The seed delivery system includes a housing having a first opening for receiving seed from the seed metering system and a second opening through which seed is discharged. The seed delivery system also includes a conveyor forming a loop with a fixed length and positioned within the housing. The conveyor is disposed around a first drive pulley and a second idler pulley. The conveyor is deformable in order to retain seed at any point along the fixed length.

摘要： A seeding machine for a row unit, in which the row unit has a seed disk rotatable about a first axis to convey seed from a seed reservoir, includes a seed delivery apparatus. The seed delivery apparatus includes an elongated housing having a first opening through which seed is received, a second opening through which seed exits, and an elongated interior chamber. The seed delivery apparatus further includes a first pulley, a second pulley, and an endless member driven by the first pulley and/or the second pulley. The endless member is movable within the elongated interior chamber to receive seed from the first opening and convey seed to the second opening. A seed diverter is movable with respect to the endless member and pivotable about a second axis non-coincident with the first axis. The seed diverter is positioned to contact and guide seed into the seed delivery apparatus.

摘要： A seeding machine with a seed meter and a seed delivery system for moving seed from a seed meter to a furrow formed in the soil. The delivery system has an endless member moving in a housing about pulleys to move seed from an upper opening in the housing to a lower discharge opening. In one embodiment, a loading wheel at the upper opening to the housing engages seed on a metering disk to move seed into the housing. The metering disk and housing can be arranged in planes parallel to one another.

摘要： A planting unit for a seeding machine having a seed meter with a metering member that moves seed sequentially along a first path to a release position at which the seed is moving in a first direction and a delivery system adapted to take seed from the metering member at the release position and control movement of the seed from the seed meter to a discharge location adjacent a seed furrow formed in soil beneath the seeding machine. The delivery system, at the release position, moves seed in a second direction along a second path. A blocking member located adjacent the first path immediately preceding the release position prevents movement of the seed in the second direction until the seed has passed the blocking member.

摘要： An agricultural planter is operable in a travel direction and a travel velocity and configured to dispense seeds into a furrow formed within an agricultural surface. An adjustment assembly is for the agricultural planter and includes a bracket configured to be coupled to a frame of the agricultural planter and a debris cleaner coupled to the bracket. The debris cleaner is configured such that during operation of the agricultural planter the debris cleaner has, relative to the travel direction, a leading edge and a trailing edge. The debris cleaner is movable such that a distance between the leading and trailing edges in the travel direction is adjustable.

摘要： A seeding machine for a row unit includes a rotatable seed disk with a plurality of apertures through which an air pressure differential is applicable to retain seed thereon. A seed delivery apparatus includes an elongated housing having a first opening through which seed is received, a second opening through which seed exits, and an elongated interior chamber. The seed delivery apparatus further includes a first pulley, a second pulley, and an endless member driven by the first pulley and/or the second pulley. The endless member is movable within the elongated interior chamber to receive seed from the first opening and convey seed to the second opening. The endless member is further positioned to sweep across a portion of the seed disk, which is controllable to angularly accelerate cooperatively with movement of the endless member to facilitate movement of a retained seed by the endless member from the seed disk.

摘要： A seed delivery system for use in a seeding or planting machine that removes the seed from a seed meter by capturing the seed therefrom. The delivery system then moves the seed down to a lower discharge point and accelerates the seed horizontally rearward to a speed approximately equal to the forward travel speed of the seeding machine such that the seed, when discharged has a low or zero horizontal velocity relative to the ground. Rolling of the seed in the trench is thus reduced. Furthermore, as the seed only has a short crop from the outlet to the bottom of the seed trench, the seed has little vertical speed to induce bounce. The delivery system uses a brush belt to capture move and accelerate the seed By capturing the seed and moving it from the meter to the discharge, the seed is held in place relative to other seeds and the planter row unit. As a result, the seeds are isolated from row unit dynamics thereby maintaining seed spacing.
