摘要： An agricultural planting machine includes a seed meter configured to meter seed, a transport mechanism configured to transport the seed to a discharge location, and a loader assembly. The loader assembly includes an element having an actuating surface, a hub configured to rotate relative to the actuating surface, and a compartment supported on the hub and configured to receive the seed from the seed meter and to eject the seed into the transport mechanism, the compartment comprising first and second movable elements that are movably coupled to the hub and configured to engage the actuating surface and move relative to the hub based on rotation of the hub relative to the actuating surface.

摘要： Devices and systems for seed capture, transport and distribution for planting fields. Seed capture devices for a seed meter may include a movable element configured to capture seeds from a seed disk of a seed meter and a power transmission element operably coupled to the movable element to drive the movable element when the seed meter is in operation and operably coupled to a mechanical contact element of the seed disk of the seed meter to drive the power transmission element when the seed meter is in operation.

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 drop 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.

摘要： A pre-metering system for feeding different types of seed into a seed meter of a planter includes separate feeder wheels that are selectively rotated to deliver different types of seed from on-row storage into the seed meter at a given time. The feeder wheels may be supported by a feeder wheel carrier that may also support various wall and ramped structures, such as upright divider walls and sloped walls that maintain separation between the different types of seeds in the on-row storage and direct the different types of seed toward the individual feeder wheels.

摘要： A system includes an agricultural metering system a meter roller configured to meter product from an agricultural product storage compartment to a product distribution system via rotation of the meter roller. The meter roller includes a first meter roller segment having a first plurality of flutes and a corresponding first plurality of recesses, and a second meter roller segment having a second plurality of flutes and a corresponding second plurality of recesses. The first meter roller segment includes a first profile, the second meter roller includes a second profile, and the first profile is different from the second profile. The system also has a dividing ring axially positioned between the first meter roller segment and the second meter roller segment.

摘要： A volumetric metering system for metering a product in an agricultural machine includes a roller element, a drive mechanism configured to rotationally drive the roller element to convey the product along a conveyance path to a product receiving component, and a guide element disposed on a side of the roller element. The guide element is configured to guide the product along the conveyance path, and is biased towards the roller element.

摘要： The present invention is directed to a seed discharge system is that employs a pair of rotating belts spaced from one another to receive the seeds from a seed metering device and to direct the seeds into the desired location within a trench over which the discharge system is positioned. The seeds are received within a gap formed between the belts and are clamped and held between the belts as the belts move, consequently moving the seeds from the seed metering device to the discharge opening of the discharge system. The constant engagement of the seeds with the belts through the discharge system prevents the seeds from bouncing, thereby maintaining a constant residence time for the seeds within the discharge system.
