Seeding machine with seed delivery system
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.
AIR SEED METER WITH ADJUSTABLE SINGULATOR
A seed metering system, for use on a row crop planter, selects individual seeds from a seed reservoir and dispenses the seeds singularly at a controlled rate. A direct drive seed metering system includes a seed disc having a plurality of suction apertures with a recessed pocket adjacent to an aperture. The recessed pockets act to agitate seeds in the seed reservoir and to direct seed flow towards the apertures. A seed path relief system provides for allowing the placement of the seeds such that they are released from an outer edge of the seed disc. An adjustable seed singulator is mounted adjacent to the face of the seed disc where inner and outer blades are adjusted radially to compensate for the singulation of various seed sizes and shapes. The seed disc is driven via engagement of an internal gear with the external gear of an independent drive motor.
Seeding machine with seed delivery system
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.
METERING APPARATUSES FOR SECTIONAL CONTROL
A metering apparatus for distributing an agricultural product in a field has a meterbox configured for association with a hopper for receiving agricultural product from the hopper. A rotatable metering element is disposed within a chamber in the meterbox, and the rotating metering element is configured to deliver the agricultural product at a regulated rate from the hopper through the chamber to a product distribution line. Delivery of the agricultural product to the product distribution line may be selectively stopped by a disengagement structure for disengaging the agricultural product from the meter roller while the meter roller continues to rotate. The disengagement structure may comprise the meter roller moveable between a lowered product engaging position and a raised product disengaging position.

A rotatable metering element is disposed within a chamber in the meterbox, and the rotating metering element is configured to deliver the agricultural product at a regulated rate from the hopper through the chamber to a product distribution line. Delivery of the agricultural product to the product distribution line may be selectively stopped by a reversibly inflatable seal between the metering element and an outlet to the distribution line, a reversible seal formed by contact between the metering element and an inlet from the hopper to the chamber, or a disengagement structure for disengaging the agricultural product from the metering element while the metering element continues to rotate.
SPRING-LOADED GUIDE TO REDUCE VARIATION IN A VOLUMETRIC METER
A volumetric metering system for metering a product in an agricultural machine is presented. In one example, the volumetric metering system comprises 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.
Method and system for placement of single seeds one by one
A method for placement of seeds one by one onto a growth medium, whereby initially seeds are extracted and singled-out from a disorderly group of seeds is disclosed. The method comprises: placement of the disorderly group of seeds onto a seed wheel which has a wheel plane, wherein the wheel plane is angled with respect to a horizontal plane such that single seeds are allowed to enter openings in the seed wheel which openings are distanced from a rotation axis of the seed wheel, whereby the seed wheel is rotated around the rotation axis which axis is perpendicular to the wheel plane thereby elevating a single seed in each opening out of the group of seeds and allowing singled-out seeds in each opening to leave the opening at a predetermined rotational position of the seed wheel and fall or trickle down a tube or chute onto a growth medium.
Dual seed meter and related systems and methods
Disclosed herein are various embodiments of dual seed meters having a metering housing having first and second seed disks with a plurality of openings arranged along a curved path of each disk, wherein the disks overlap to form a convergence region such that seed traveling along the curved paths is delivered to a single point. Certain implementations also have a vacuum chamber defined between a first wall of the metering housing and the first and second seed disks and a seed chamber defined between a second wall of the metering housing and the first and second seed disks.
