Abstract
A method of harvesting a seed from a rooted plant utilizing a seed harvester. The method includes dislodging the seed from the rooted plant via a seed dislodging system on the seed harvester by contacting the rooted plant with at least one of a plurality of dislodging members of the seed dislodging system. The method also includes collecting the seed via a seed collection system on the seed harvester. The method further includes transporting the seed via a seed transport system on the seed harvester from the seed collection system to a seed isolation system on the seed harvester. The method also includes isolating the seed from a waste material via the seed isolation system. A seed harvester is also included.

A method of harvesting seeds from a living and rooted plant utilizing a seed harvester, the method comprising:
- receiving the living and rooted plant within a pass-through opening of a seed dislodging system on the seed harvester and within a slot disposed between first and second collection reservoirs of a seed collection system, the pass-through opening having a height and a width with a plurality of dislodging members disposed within the pass-through opening, the plurality of dislodging members including a first dislodging member extending in a heightwise direction along a first side of the pass-through opening, a second dislodging member extending in the heightwise direction and spaced apart from the first dislodging member in a widthwise direction along a second side of the pass-through opening opposite the first side, and a third dislodging member extending in the widthwise direction and across a top of the pass-through opening with the first and second collection reservoirs disposed along a bottom of the pass-through opening such that the living and rooted plant passes through the slot and the pass-through opening as the seed harvester moves along a row of living and rooted plants;
- contacting the living and rooted plant with the dislodging members of the seed dislodging system on the seed harvester and thereby dislodging the seeds from the living and rooted plant in a nondestructive manner such that the plant remains living and rooted after the seeds have been dislodged;
- collecting the seeds via the seed collection system on the seed harvester with one or more of the seeds falling into at least one of the first and second collection reservoirs and generating pressurized gas flow drawing one or more of the seeds upwardly from a top of the living and rooted plant into the seed collection system through a passage disposed along the top of the pass-through opening adjacent the third dislodging member;
- transporting the seeds via a seed transport system on the seed harvester from the seed collection system to a seed isolation system on the seed harvester;
- and,
- isolating the seeds from a waste material via the seed isolation system.

A seed harvesting header for a seed harvester, the seed harvesting header operable to dislodge associated seeds from an associated row of associated living and rooted plants, the seed harvesting header comprising:
- a first sidewall and a second sidewall opposite the first sidewall such that a pass- through opening is at least partially defined therebetween, the first sidewall positionable along an associated first side of the associated row of associated living and rooted plants and the second sidewall positionable along an associated second side of the associated row of the associated living and rooted plants such that the associated row of associated living and rooted plants travels through the pass-through opening during travel of the seed harvesting header;
- a collection shroud extending in a widthwise direction between the first and second sidewalls and across a top of the pass-through opening, the collection shroud including a passage extending therethrough in fluid communication with the pass-through opening;
- a first dislodging member extending in a heightwise direction, the first dislodging member supported along the first sidewall and extending into the pass-through opening from along the first sidewall a distance sufficient to contact the associated living and rooted plants along the first side of the associated row thereof;
- a second dislodging member extending in the heightwise direction, the second dislodging member supported along the second sidewall and extend into the pass-through opening from along the second sidewall a distance sufficient to contact the associated living and rooted plants along the second side of the associated row thereof;
- a third dislodging member extending in the widthwise direction, the third dislodging member supported across the top of the pass-through opening and extending into the pass-through opening a distance sufficient to contact the associated living and rooted plants along a top of the associated row thereof;
- a collection reservoir beneath at least one of the first dislodging member and the second dislodging member;
- and,
- an air pressure source in fluid communication with the passage in the collection shroud and operable to draw dislodged seeds into the passage from along a top portion of an associated living and rooted plant during use of the seed harvesting header.
5 more elements
A seed harvester comprising:
- a plurality of headers coupled to the seed harvester with at least one of the plurality of headers including:
- a seed dislodging system including a pass-through opening dimensioned to receive an associated plant, the seed dislodging system configured to dislodge an associated seed from the associated plant as the associated plant passes through the pass-through opening;
- and,
- a seed collection system disposed in communication with the seed dislodging system, the seed collection system configured to collect the associated seed dislodged from the associated plant via the seed dislodging system;
- and,
- a seed transport system in communication with the seed collection system and operable to transport the associated dislodged seed out of the seed collection system and into a feed duct in communication with the seed collection system through an inlet, a pump duct coupled to the feed duct and configured to assist in transporting the associated dislodged seed through the feed duct utilizing a positive pressure source, and a blockage clearance system including a nozzle disposed in fluid communication with the feed duct adjacent inlet, the blockage clearance system operable to selectively deliver pressurized gas to the nozzle.
