A nc\,. This process unfortunately causes significant damage to mature and immature flowers and allows for about two harvests before the canopy is effectively destroyed. Most native grass seeds are hard to harvest and naturally shatter quickly once they are mature. Several species are known to possess seed characteristics similar to hoary tansyaster, namely indeterminate ripening and light airborne dispersal, and may be effectively harvested with a chain-modified Flail-Vac. 3, thereby providing access to the collected seeds. Photo by Derek Tilley. The seed harvester of the instant invention comprises an elongated hollow housing adapted for support from front loader bucket arms mounted on a tractor with the housing extending transversely of the forward end of the tractor. 4 Figure 1. Loops of heavy log chain replaced the rigid pipe rake allowing for multiple, non-destructive harvests. Though precise comparisons can’t be made because we harvested in subsequent years under different conditions, we observed a clear improvement in hoary tansyaster seed yields due to the increased number of harvests performed. The force of friction strips the seed off the stalk. Vacuum harvesting of seeds. An elongated seed stripping rotary brush is journaled in the housing for rotation about an axis extending longitudinally thereof with between 30° and 90° of the periphery of the brush registered with the inlet. Hand or vacuum-assisted harvesting is often used, but can be labor intensive and increase costs. 3 of the drawings whereby the brush bristles 56 swing pass the marginal portion 50 into the inlet 46 and from the inlet 46 pass the marginal portion 52. Over the last few years we have examined several techniques for harvesting light airborne seed with varying levels of success. ... high output blower, with built in seed cup vacuum, 3 point hitch mounted, very low acres on seeder Argicola Italiana Carrot Seeder. We completed two harvests using the Flail-Vac for a combined total of 7.3 lb (3.3 kg) of pure seed, equivalent to 12.2 lb/acre (13.7 kg/ha). & Terms of Use. Vac Stripper brush harvester. The dispersal units of some native grasses (e.g. The main object of this invention is to provide an effective seed harvester which may be utilized to harvest seeds from tall grasses. Harvested material from a standard Flail-Vac contains significant amounts of vegetative material. Hoary tansyaster exemplifies the problems associated with harvesting fluffy seed that ripens over a long maturation window.

Photo by Derek Tilley. 2 is an enlarged fragmentary top plan view of the left hand portion of the structure illustrated in FIG. Leaf vacuums and jet harvesters developed for harvesting forb seed work well, but creating even distribution of the suction has been problematic. The foregoing is considered as illustrative only of the principles of the invention. Seed separating structure is provided within the air passage intermediate the inlet and outlet and is operative to separate seeds from the air flow moving through the passage. In 2015 we experimented with two modifications to the standard Flail-Vac harvester in an attempt to increase yields of pappus-bearing seed. The housing has been constructed for support from the vertically swingable support arms of a front loader bucket supporting mechanism mounted on a tractor. Whilst they are useful for … Flail-vacuum seed harvester 1. The housing 16 defines an air passage 44 extending therethrough including an inlet 46 and an outlet 48. To harvest seed, you hold the box with one hand and use your other hand to hold the stalks in place while pulling the box across the plant material. The use of a Flail-Vac harvester (Woodward Flail-Vac Seed Stripper, Ag-Renewal Inc., Weatherford, Oklahoma), can be a viable alternative in some cases, but this harvester can be highly destructive, and it limits the number of times one can go through the field. cotton air harvesters use atmospheric pressure (air flow, vacuum,) to extract seed cotton much like hand picking, in that the pickers fingers would reach around the seed cotton and pull the seed cotton from the cotton burr, without pulling the burr from the cotton stalk, thus making cotton air harvesters self-cleaning extractor row units the perfect apparatus for vacuum cotton … In the first iteration we created a rigid pipe rake by mounting thirteen 24-inch (61 cm) lengths of 0.75 inch (1.9 cm) galvanized tubing to the front of the Flail-Vac hood. 5). In the second iteration we removed the lengths of pipe and replaced them with loops of heavy chain (Fig. We went through a 1.0 acre (0.4 ha) field a total of 8 times over a period of 21 days with the modified Flail-Vac. However, most of these harvesters utilize complex structure for separating seeds from the grass stalks and further utilize their own mobile platforms. The brush creates a vacuum, pulling the seed head into the brush. A rotating ‘beater / brush’ mounted inside the head unit helps to dislodge seed from the grass stem. A hydraulic motor 56 is supported from the end 24 and drives the brush 54 in a clockwise direction as viewed in FIG. The marginal portion 52 is spaced forward and above the marginal portion 50 with the vertical spacing of the marginal portion 52 above the marginal portion 50 being greater than the horizontal spacing of the marginal portion 52 forward of the marginal portion 50. This technique both damages the plant, limiting the number of harvest, and accumulates significant amounts of vegetative material with the harvested seed. 1).
