20100192819 | 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. | 08-05-2010 |
20100224110 | Seed Meter And Seed Disk With Peripheral Edge Seed Pick-Up - A seed meter with a flat seed disk with seed apertures on the peripheral edge of the disk results is provided. The seed pick-up on the disk edge enables a more predictable seed trajectory thereby improving the accuracy of seed spacing. With seed pick-up on the disk periphery, the seed reservoir in the meter housing is located rearward of the disk as opposed to the side of the disk, resulting in a narrowing of the meter housing, making it easier to package two meters close together for twin row planting or to lower the meter in the row unit, reducing the seed drop distance. With improved seed placement accuracy, the planter travel speed can be increased. Further efficiency is gained by a vacuum clean-out of the seed meters, reducing the time required to change seed type or variety. | 09-09-2010 |
20100307394 | VOLUMETRIC METERING SYSTEM WITH SECTIONAL SHUT-OFF - A volumetric metering system for a seeding machine is provided with movable gates disposed downstream from the meter roller but before the product enters a distribution system to selectively stop the flow of product through sections of the metering system. By placing the shut-off gate after the meter but before product enters the distribution system, there will not be a delay in stoppage of product flow while the meter empties of product. Furthermore, by locating the gate before the distribution system, the metered product is not mixed with the air stream or with additional products, causing a need for product redirection into a pressurized tank or separation of multiple products. | 12-09-2010 |
20100307395 | VOLUMETRIC METERING SYSTEM WITH SECTIONAL SHUT-OFF - A volumetric metering system for a seeding machine is provided with a plurality of movable inserts each insert defining a ledge over which the seed falls to the meter outlet. The inserts are selectively movable between an open position in which seed is allowed to flow over the ledge and a closed position in which the inserts close the product flow to the outlet. By locating the product shut-off after the meter but before product enters the distribution system, there will only be a short delay in stoppage of product flow once the shut-off is closed. | 12-09-2010 |
20110232549 | Seed meter control - A seed metering apparatus having a selectably actuated panel positioned between the metering apparatus and discharge chute, the panel moving between an open position and a closed position such that seeds may be more accurately spaced and metered without disrupting the drive mechanism of the seed metering apparatus.

The manifold actuator assembly may also be used as a locking apparatus to lock and unlock members in a wide variety of applications. | 03-22-2012 |
20130036956 | SEEDING MACHINE WITH SEED DELIVERY SYSTEM - A seed delivery system for use in a seeding machine that removes seed from a seed meter by capturing seed therefrom. The delivery system moves seed down to a lower discharge point and accelerates seed horizontally rearward to a speed approximately equal to the forward travel speed of the machine such that the seed, when discharged has a low or zero horizontal velocity relative to the ground. 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, each 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. | 02-14-2013 |
20130298810 | 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.
