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.

Seeding machine with seed delivery system

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.

A seed delivery system for a seeding machine having a seed meter comprises a housing that defines an upper seed loading area and a lower seed discharge area. A drive pulley is mounted to rotate with respect to the housing. A belt is supported for rotation by the drive pulley within the housing. A loading wheel is mounted to rotate with respect to the housing to transfer seeds from the seed meter into the belt at the seed loading area. The belt conveys the seeds through the housing as the belt travels from the seed loading area to the seed discharge area.

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.

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 blocking loading surface guides seed from the metering member of the seed meter and into the delivery system.
