Abstract
The Multipurpose Leaf Crop Harvesting Apparatus and Processing Method will accomplish seven steps in one pass of the combine harvester. This apparatus and processing method harvests leaf crops and is configured to perform multiple processing operations, including fractionation of the leaf crop, leaf maceration, leaf sizing, elevating the leaf fraction to a transport vehicle, and stem conditioning, cutting and windrowing, in a single pass through the crop field. These steps are accomplished using a header unit, an adapter feeder macerator and a forage harvester vehicle, expeditiously removing the leaf fraction from the field. Following leaf fraction harvesting, the leaf fraction is processed by densification into forage feed products. The processed leaf fraction can be combined with other feeds to make up customized feed rations. The stem fraction is also processed. The present invention can also be used to harvest grass crops.

[0101] For a fuller understanding of the nature and advantages of the Multipurpose Leaf Crop Harvesting Apparatus and Processing Method, reference should be had to the following detailed description taken in conjunction with the accompanying drawings which are incorporated in and form a part of this specification, illustrate embodiments of the design and together with the description, serve to explain the principles of this application.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0102] Referring now to the drawings, wherein similar parts of the Multipurpose Leaf Crop Harvesting Apparatus and Processing Method 10 are identified by like reference numerals, there is seen in
[0103] Referring now to the Multipurpose Leaf Crop Harvesting Apparatus and. Processing Method 10 as shown in
[0104] Block 14-Step 2 indicates the leaf macerating step where leaves are run through a macerator to rupture the cells of the plant leaf to speed up the drying process.
[0105] Block 16-Step 3 indicates leaf forage sizing step where the leaves are conveyed into a chopper to size the leaf fraction for processing. It is anticipated that the leaf sizing and maceration could take place within the harvester, or alternatively, on site at the processing facility after the leaf fraction is transported to that facility.
[0106] Block 18-Step 4 indicates where the leaf fraction is elevated into a transport vehicle or trailer and taken by truck to a drying facility for curing and processing, wherein such processing steps are performed expeditiously after harvesting.
[0107] Block 20-Step 5 indicates the stem conditioning, the first step in which the leaf crop stems are cut, conditioned, and windrowed in the same pass. This leaf combine completes seven steps in one pass, and because it removes the leaf fraction from the field expeditiously after being harvested, this harvesting process eliminates weather associated harvest risks to the high value leaf fraction.
[0108] Block 22-Step 6 indicates the stem mowing step where the stems are mowed and cut.
[0109] Block 24-Step 7 indicates the stem fraction step where the plant will be windrowed or may be conventionally sun cured, raked and baled. The stem conditioning, cutting and windrowing operations can be accomplished in the same pass. This leaf crop harvesting combine completes each of these seven steps in one pass, thereby eliminating weather associated harvest risks to the high value leaf fraction. The valuable leaf fraction is expeditiously removed from the field to be further processed, while the less valuable stem fraction remains in the field and can be expeditiously baled or removed contemporaneously.
[0110] Therefore, it should be understood that the multipurpose leaf crop harvesting apparatus is configured to be capable of performing one or more the following seven operations in one pass through a crop field:
[0111] a) leaf stem fractionation;
[0112] b) leaf maceration;
[0113] c) leaf forage sizing;
[0114] d) elevation of leaf fractions onto a transport vehicle;
[0115] e) stem conditioning;
[0116] f) stern mowing/cutting; and
[0117] g) stem windrowing;
[0118] wherein said multipurpose leaf crop harvesting apparatus enables the direct and expeditious removal of the leaf crop leaf fraction from the Cr op field upon harvest of the leaf crop simultaneously with the seven operations performed.
[0119]
[0120] Therefore, it should be understood from
[0121] First, providing a multipurpose leaf crop harvesting apparatus which is configured to be capable of performing one or more of the following seven operations in one pass through a crop field: 1) leaf stem fractionation; 2) leaf maceration; 3) leaf forage sizing; 4) elevation of leaf fraction onto a transport vehicle; 5) stem conditioning; 6) stem mowing/cutting; and 7) stem windrowing; wherein said multipurpose leaf crop harvesting apparatus enables the direct and expeditious removal of the leaf crop leaf fraction from the crop field upon harvest of the leaf crop simultaneously with the seven operations performed.
[0122] Second, transporting the leaf fraction to a processing plant where the leaf fraction is expeditiously densified which normally includes drying; and formulated into feed rations per customer feed ration requirements. Other forms of leaf fraction densification are also anticipated.
[0123] Third, forming the resulting feed rations into hales, bale bags, cubes and pellets for distribution and marketing of the feed rations generated, wherein the processing steps are taken expeditiously after harvesting the leaf crop to generate the formulated forage feed rations per customer feed ration requirements. In this way, a leaf crop forage feed ration product is generated employing the method of harvesting and processing a harvested leaf crop comprising the above enumerated steps, wherein the forage feed ration is subsequently processed into custom feed ration products by the addition of feed additives as per customer requirements.
[0124] The stem fraction of the plant will be conditioned (broken and damaged to expose inner moisture and expedite drying), cut and windrowed after the leaf fraction has been removed. In addition to the leaf fraction being densified then utilized, the stem fraction can also be densified, then utilized by further processing into animal rations. Several anticipated ways to utilize the stem fraction include (1) double compressing the stem fraction will yield a softer and more palatable product for animals; (2) chopping the stem fraction will create a loose form which may then be added to pellets and cubes, thereby creating a customized animal ration. In this way, a leaf crop stem fraction forage feed ration product is generated employing the method of harvesting and processing a harvested leaf crop comprising the above steps, wherein the stem forage feed ration is processed into custom feed ration products by the addition of feed additives as per customer requirements. Moreover, the stem fraction may be sold directly as bales, or further processed into any of many varying forms to be used as a feed ration or to be mixed into feed ration formulations. Additionally, the stem fraction may also be densified and used as a biofuel.
