Patent Application
20180213722
This application describes an multipurpose leaf crop harvesting apparatus and processing method that harvests leaf crops and grasses and is capable of performing seven different processes including in-field fractionation of leaf crop leaves and stems, leaf maceration of the leaf fraction, leaf forage sizing, elevating the leaf fraction to a transport vehicle or trailer, as well as cutting the stem fraction, conditioning the stern fraction and windrowing the stem fraction for later baling, all in a single pass through the crop field.
The present problem is the inconsistent quality of product, inclement weather, and leaf loss at harvest. Animals produce better yields and are healthier when given consistent proper nutrition. Leaves in alfalfa, whether they are harvested early or late in the growth cycle of the plant, make up a primary component of a resulting feed ration derived from harvested alfalfa. Using the Multipurpose Leaf Crop Harvesting Apparatus and Processing Method, the leaf fraction of the plant can be harvested for optimal leaf yield. The conventional methods for producing quality alfalfa are responsible for losing about 24% of the high-quality leaf yield potential due to harvest intervals, poor weather, and mechanical losses.
The Multipurpose Leaf Crop Harvesting Apparatus and Processing Method eliminates all but 3-5% of leaf loss, increases nutritional values by retaining water soluble nutrition by quickly drying leaf fraction, and eliminating harvest weather risks to the leaf fraction. The conventional method for producing dried alfalfa has not changed since the 1950's. Alfalfa is cut, conditioned, windrowed, raked, baled, and stacked. The sizes of both the machinery and the bales have gotten bigger and faster over time but the basic process has remained the same. Conventional haying faces the following problems: mechanical yield loss at each step of the process, yield and quality losses due to the harvest weather risks of rain, hail, humidity, wind, too much dew, not enough dew and sun bleach producing an inconsistency of product due to the maturation and ever-changing feed quality of the stem fraction.

What is Alfalfa Leaf Hay? The Alfalfa Leaf Hay process fractionates the alfalfa plant. The leaf fraction is separated from the stem fraction of the alfalfa plant at harvest. The high value, high quality leaf fraction is taken directly from the field to be cured in a dryer and the stem fraction is left in the field to be sun cured. This eliminates leaf fraction harvest weather risk and increases the yield of the harvested leaves by about 24% through reduced harvest leaf loss and the ability to time the harvest for maximum leaf fraction yield. The leaf and stem products can then be used to provide the customer with the exact alfalfa nutrition required for their animals,
Numerous innovations for the harvesting alfalfa have been provided in the prior art that are described as follows. Even though these innovations may be suitable for the specific individual purposes to which they address, they differ from the present design as hereinafter contrasted. The following is a summary of those prior art patents most relevant to this application at hand, as well as a description outlining the difference between the features of the Multipurpose Leaf Crop Harvesting Apparatus and Processing Method.
U.S. Pat. No. 4,678,129 of James F Dallenger describes a crop processor for forage harvesters that includes a paddle wheel assembly for replacing the lower compressor roll of a compressor roll assembly. The paddle wheel assembly includes paddles arranged to convey crop material that has been previously cut and chopped by a cutter head toward a discharge blower while causing only minimal further conditioning of the cut and chopped crop material. When harvesting grass crops such as alfalfa, the paddle wheel assembly prevents plugging of the crop processor.
This patent describes a modification to a crop processor for forage harvesters that includes a paddle wheel assembly but does not describe the unique features of the Multipurpose Leaf Crop Harvesting Apparatus and Processing Method capable of performing multiple steps in one pass of the harvester, to directly remove the crop from the field and reduce the risk of damage to the crops by moisture when it is left in the field to dry before processing.
U.S. Pat. No. 5,884,225 of Michael S. Allen et al, describes a system and a method for providing farmers/producers with crop characteristic predictions for standing crops located in fields includes a central database for storing field and crop information for the crops. A weather data processor receives raw weather data from either or both of (1) a weather data service with collected weather data from a plurality of weather stations; and (2) one or more site specific weather stations associated with a particular field whose information is in the database. The raw weather data are processed to obtain field weather parameters for entry into a crop characteristic prediction equation, and the parameters are stored in the central database. With a user interface, a crop whose information is stored in the central database is selected. A computer calculates a crop characteristic prediction for the selected field based on the crop and field information stored in the central database, including the field weather parameters in the database, and the crop characteristic prediction formula. The producer uses the prediction to determine time of harvest. In one embodiment, the crops are alfalfa crops and the crop characteristic is neutral detergent fiber content.
This patent describes a system and a method for providing farmers/producers with crop characteristic predictions for standing crops regarding the possibility of crop damage to the crops harvested and left on the field when inclement weather changes create rain or hail which can damage the crops. By harvesting using the Multipurpose Leaf Crop Harvesting Apparatus and Processing Method capable of performing multiple steps in one pass of the harvester to directly remove the crop from the field, the risk of damage to the crops by moisture when it is left in the field to dry before processing, are significantly reduced.

None of these previous efforts, however, provides the benefits attendant with the Multipurpose Leaf Crop Harvesting Apparatus and Processing Method. The present design achieves its intended purposes, objects and advantages over the prior art devices through a new, useful and unobvious combination of method steps and component elements by employing readily available equipment and materials.
In this respect, before explaining at least one embodiment of this application in detail it is to be understood that the process is not limited in its application to the details of construction and to the arrangement of the components set forth in the following description or illustrated in the drawings the Multipurpose Leaf Crop Harvesting Apparatus and Processing Method is capable of other embodiments and of being practiced and carried out in various ways. In addition, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting. As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for designing of other applications and systems for carrying out the several purposes of the present design. It is important, therefore, that the claims be regarded as including such equivalent processes insofar as they do not depart from the spirit and scope of the present application.
The principal advantage of the Multipurpose Leaf Crop Harvesting Apparatus and Processing Method is to provide a method for fractionating plants into their leaf and stem parts to increase yield, quality and marketability.
Another advantage of the Multipurpose Leaf Crop Harvesting Apparatus and Processing Method is to strip the leaf from the standing plant and size and, macerate the leaf in preparation for processing the leaf into its final product.

Another advantage of the Multipurpose Leaf Crop Harvesting Apparatus and Processing Method by making one pass over the field is the savings in labor, machine time and fuel costs, and lessens crop field soil compaction.
Another advantage of the Multipurpose Leaf Crop Harvesting Apparatus and Processing Method is to provide a unique single pass harvesting leaf combine to process and remove the high-quality leaves from the field and cut and windrow the stems to be baled for transport to be processed.
These together with other advantages of the Multipurpose Leaf Crop Harvesting Apparatus and Processing Method along with the various features of novelty, which characterize the design, are pointed out with particularity in the claims annexed to and forming a part of this disclosure. In this respect, before explaining at least one of the embodiments of the Multipurpose Leaf Crop Harvesting Apparatus and Processing Method in detail it is to be understood that the design is not limited in its application to the details of construction and to the composition set forth in the following description or illustrated in the drawings. The Multipurpose Leaf Crop Harvesting Apparatus and Processing Method are capable of other embodiments and of being practiced and carried out in various ways. In addition, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting.
The Multipurpose Leaf Crop Harvesting Apparatus and Processing Method have been developed to harvest the leaf fraction directly from the field and take it expeditiously to a processing facility where the leaf fraction will be densified, for example dry-cured. The removed leaf fraction is transported to the processing facility expeditiously to prevent/stop cellular respiration. Expeditiously can be defined herein as the time necessary to arrest and stop cellular respiration, typically 10 to 90 minutes. The densified leaf fraction can then be processed into a customer-desired forage feed ration product.
The Multipurpose Leaf Crop Harvesting Apparatus and Processing Method strips the leaves of a standing plant such as alfalfa. The leaves are conveyed into a chopper to size the leaf fraction for processing. The leaves are run through a macerator to rupture the cells of the plant leaf to speed up the drying process. The sized, chopped and macerated leaf fraction is then elevated onto a trailer. 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.
The stem fraction of the plant will be cut, conditioned and windrowed after the leaf fraction has been removed. In addition to the leaf fraction being utilized, the stem fraction can also be used and processed into animal rations. Several anticipated ways to utilize the stem fraction include: (1) Double compressing the stern 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. Moreover, the stem fraction may be sold directly as bales. The stem fraction may also be used as a biofuel.
The Multipurpose Leaf Crop Harvesting Apparatus and Processing Method, will include a stripper header, chopper, macerator, elevator and railer for the leaf fraction and a cutting head, conditioner and windrower for the stem fraction. This process can be applied to a wide variety of leaf crop plants like legumes such as Alfalfa, Clover, Sainfoin, Birdsfoot Trefoil and Austrian Winter Peas, as well as grasses and green (not ripe) plant seed head removal of grasses, such as Timothy, Orchard, Bermuda, Brome, Bluegrass Oat and Barley, Wheat, and Triticale, and many other leaf stem plants or other green grass seed head plants.
Production Requirements
The leaf fraction will be fractionated, sized, and elevated for transportation in one, pass. The stem fraction will be cut in a separate pass using a conventional hay swather. The macerator will be located at the production facility prior to drying. However, we are working to build a machine that will incorporate the steps of fractionation, maceration, sizing, elevating, and cutting the stem fraction all in one pass. This process improves nutritional values, eliminates harvest weather risks and prevents losses in quality to the leaf fraction from bleaching, prolonged plant respiration, dirt, mold and decay. The quick drying of the leaf fraction improves carbohydrate retention by stopping plant respiration much faster than is possible in the conventional baying process. The consistency of the leaf fraction will make it possible to formulate consistent high-quality rations for the varying feed requirements in an animal's life cycle.
Livestock and pets have optional nutritionally balanced diets based on the stage of life and production utility. The fractionation of the plants will allow animal nutritionists to better optimize feeding rations for animal health and performance. This will also allow producers to better balance the feed rations of the animals. The leaf fraction provided can be mixed with any available fiber, feed and supplement to create the ideal consistent ration for optimal production and health. This invention allows for higher yields per acre, higher quality per ton produced, eliminates weather risk to the high value leaf fraction and nutritional consistency to the end user.
The conventional method for the producing dried alfalfa has not changed since the 1950's. Alfalfa is cured, conditioned, windrowed, raked, baled and stacked. The sizes of both the machinery and the bales have gotten bigger and faster over time but the basic process has remained the same. Conventional haying faces the following problems; mechanical yield loss at each step of the process, yield and quality losses due to the harvest weather risks of rain, hail, humidity, wind, too much dew, not enough dew and sun bleach along with the inconsistency of product due to the maturation and ever-changing feed quality of the stem fraction. Using the Multipurpose Leaf Crop Harvesting Apparatus and Processing Method, the leaf fraction of the plant can be harvested for optimal leaf yield. The conventional methods for producing quality alfalfa are responsible for losing 10% to 40% of the high-quality leaf yield potential due to harvest intervals, poor weather, and mechanical losses. The present Multipurpose Leaf Crop Harvesting Apparatus and Processing Method, for alfalfa leaf hay process, for example, eliminates all but 3 to 5% of leaf loss, and eliminates harvest weather risks to the leaf fraction.
Leaves are leaves in alfalfa; however, alfalfa forage quality changes daily through the maturation of the stem fraction of the plant Leaves harvested in the vegetative state through 40% bloom have the highest nutritional value. This harvesting and curing process gives customers nutritionally consistent, highly palatable products tailored to animal feeding requirements. Separate leaves in a process that strips the leaves from the stems macerates the leaves, sizes the leaf fraction for drying and elevates the leaves onto a truck. The sterns are cut, conditioned, and windrowed in the same pass. This leaf combine completes seven steps in one pass, eliminating weather associated harvest risks to the high value leaf fraction, and increases leaf yield by 15% to 30% over conventional methods. However, timing for maximum leaf expression will increase yields, extend stand life and result in fewer harvests per year.
The leaf fraction of the alfalfa will be transported by truck to a processing facility for densification, drying, curing and a wide variety of other further processing operations. The leaf fraction will be dried as soon as possible to stop respiration for maximum nutritional value. The stem fraction of the plant will be conventionally sun cured, raked and baled. The same can be accomplished with green (not ripe) grass seed heads and resulting stripped grass stems.
Alfalfa fractionation brings customizable product consistency to the market. Higher yields (due to mechanical efficiencies and harvest timing) and leaf fraction weather risk abatement allow for more profitability as compared to existing conventional haying methods. The nutritional consistency and superior palatability of these products will be highly sought after in the marketplace and new markets will be opened to alfalfa targeted products. Animal nutritionists will be able to have a more consistent ration for livestock and pets.
Export markets will be more accessible. Dozens of leaf fraction processing facilities will be located in targeted geographical areas across the USA and beyond to change the way alfalfa is harvested and marketed worldwide. The production of alfalfa has not changed in 75 years beyond the size and speed of equipment and bales. Alfalfa fractionalization, technology brings greater yields per acre of the high value leaf fraction, higher quality per ton, decreased weather risks, and accomplishing fractionation and removal in one pass lessens crop field soil compaction. All of this adds up to increased profitability to the forage industry. We have the potential for branding high quality products and carving out a large percentage of the alfalfa industry.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of this application, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art. All equivalent relationships to those illustrated in the drawings and described in the specification intend to be encompassed by the present disclosure. Therefore, the foregoing is considered as illustrative only of the principles of the Multipurpose Leaf Crop Harvesting Apparatus and Processing Method. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the design to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of this application. It should also be realized by those skilled in the art that such equivalent constructions and methods do not depart from the spirit and scope of this application as set forth in the appended claims.
The accompanying drawings, which are incorporated in the Multipurpose Leaf Crop Harvesting Apparatus and Processing Method and form a part of this specification, illustrate embodiments of the and together with the description, serve to explain the principles of this application.
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.
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
Referring now to the Multipurpose Leaf Crop Harvesting Apparatus and. Processing Method 10 as shown in
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.
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.
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.
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.
Block 22-Step 6 indicates the stem mowing step where the stems are mowed and cut.
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.
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:
a) leaf stem fractionation;
b) leaf maceration;
c) leaf forage sizing;
d) elevation of leaf fractions onto a transport vehicle;
e) stem conditioning;
f) stern mowing/cutting; and
g) stem windrowing;
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.

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.
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.
