Description
- This application is a continuation application of U.S. Ser. No. 12/262,271 filed Oct. 31, 2008 which claims priority under 35 U.S.C. §119 to a provisional application, U.S. Ser. No. 60/984,719 filed Nov. 1, 2007, which is hereby incorporated by reference in its entirety.
- The present invention relates to air flow separation associated with a harvesting machine, more particularly, but not exclusively, the present invention relates to air flow separation of a harvesting machine which is adapted to harvest grain as well as biomass material also sometimes referred to as crop residue, cellulosic material, stover, or material other than grain (MOG) which may include leaves, stalks, husks, chaff, or any other material that passes through a combine but is not removed in the grain stream.
- Harvesting machines or combines are self-propelled machines which harvest, thresh, separate, and clean an agricultural crop. The resulting clean grain is stored in a grain tank located on the harvesting machine and can be transported from the grain tank to a wagon, cart, truck, or other container by an unloading auger. In a typical process, after separation and threshing of the grain, it is directed to a cleaning system that typically includes a cleaning shoe having a chaffer and a sieve. A cleaning fan directs aspirated air through the chaffer and sieve blowing the lighter chaff and straw out the rear of the combine. The clean grain, being heavier falls through the chaffer and sieve and may be collected by a clean grain auger which directs it to a clean grain elevator which conveys the clean grain to the grain tank.
- One of the problems with combines is providing sufficient airflow out of the cleaning shoe, particularly in a manner which does not add increased complexity to the design or operation of the combine. Another seemingly unrelated problem to one not having the benefit of this disclosure involves biomass collection and the addition air flow related problems introduced by biomass collections. Thus, what is needed is a combine with an air movement unit that assists in biomass conveyance or enhances combine performance.
- Therefore, it is a primary object, feature, or advantage of the present invention to improve over the state of the art.
- According to one aspect of the present invention, a harvesting machine includes a self-propelled vehicle adapted for separating grain from non-grain material, a cleaning shoe and a fan for controlling air flow. The fan is positioned downstream of the cleaning shoe and the fan having an air inlet for providing air to the fan and an aspiration outlet for providing air from the fan. The fan assists in reducing static air pressure within the harvesting machine.
- According to another aspect of the present invention, a harvesting machine includes a self-propelled vehicle adapted for separating grain from non-grain material, a chopper operatively connected to the vehicle and adapted for receiving the non-grain material and chopping the non-grain material, a blower adapted for assisting in conveying the non-grain material from the chopper, a fan for controlling air flow; an air inlet for providing air to the fan, and an aspiration outlet for providing air from the fan.
- According to another aspect of the present invention, a method for controlling air flow includes providing a harvesting machine comprising (a) a self-propelled vehicle adapted for separating grain from non-grain material, (b) a cleaning shoe, (c) a fan for controlling air flow, the fan positioned downstream of the cleaning shoe and the fan having an air inlet and an aspiration outlet, and (d) wherein the fan assists in reducing static air pressure within the harvesting machine. The method further includes intake of air through the air inlet of the fan and aspirating air through an aspiration outlet of the fan. The fan can have other functions, included but not limited to, separation of lighter non-grain material from heavier non-grain material.

FIG. 1 illustrates a combine harvester orharvesting machine 10 which is adapted for both harvesting biomass as well as spreading biomass. Theharvesting machine 10 may be based on a self-propelled combine such as a John Deere 9750STS combine or similar platform. Aresidue chopper 12 is provided. Aheader 11 is shown on the front of theharvesting machine 10. In addition, a particle accelerator orsilage blower 14 from a self-propelled forage harvester is mounted behind thechopper 12. Theblower 14 may be from a John Deere 7500 self propelled forage harvester or similar blower and is mounted on the back of theharvesting machine 10 immediately behind thechopper 12. Theblower 14 is a device used in conveying material. The blower may include a shaft upon which a series of paddles are mounted radially from the center. Material is fed tangentially into the perimeter of the paddles so the paddles hit and accelerate the material. Through the use of atransition member 13, all or a certain fraction of material flowing through thechopper 12 may be discharged either onto the ground or through theblower 14. A deflector plate may be positioned immediately below thetransition member 13. When thetransition member 13 is set to collect the crop residue, crop residue material is sent to theblower 14, and the crop residue material may then be blown through thechute 16 into a wagon or truck or other support vehicle to be removed from the field. Anair movement unit 20 having one or more fans may be mounted on a rearward portion of thecombine 10. -
FIG. 2 illustrates a cross section of aharvesting machine 10. Note that biomass material leaving thechopper 12 is either discharged at thetransition member 13 or conveyed by theblower 14 through thechute 16. The position of thetransition member 13 may be set through hydraulic, electronic, or other type of control so that 0 to 100 percent of the biomass material leaving the chopper is spread and that a corresponding 100 to 0 percent of the biomass material is collected.FIG. 4 illustrates thecombine 10 with anair movement unit 20 including one ormore fans 22 positioned at the back end of thecombine 10. Eachfan 22 is a device used to move air. One or more centrifugal fans, each having paddles mounted radially outward from a center shaft may be used. Eachfan 22 moves air from an inlet at the center to outlets at the perimeter. As air moves into eachfan 22, the paddles accelerate it and the air is forced outwardly by centrifugal force. Thefans 22 used need not be centrifugal fans. Thefans 22 may be mounted on a common shaft with theblower portion 14, or the fans may be remote mounted. Mounting on a common shaft may reduce complexity, parts, and maintenance compared to remote mounting. However, remote mounting will allow thefans 22 to be used for air movement when the combine is utilized in normal operation without biomass harvest. Havingfans 22 co-located with ablower 14 at the exit of thecombine 10 will increase combine efficiency, increase dust control, and assist feed into the chopper by evacuating air, as well as separating heavy and light materials through aspiration in and after the blower segment. In addition, it is to be understood that fan size may be adjusted in either the width or radial dimensions to alter the amount of airflow needed and the application at hand. Applications may include, without limitation, increased aspiration for separation of heavy and light materials, improved feeding through the chopper, improved grain shoe performance, improved dust control, and improved stover spreading. - The
air movement unit 20 shown is positioned between thechopper 12 and theblower 14. The air aspiration conduit oroutlet 28 is shown after theblower 14 to provide for cross aspiration and theair inlet 24 is shown between thechopper 12 andblower 14. - A
harvesting machine outlet 30 is shown after thechopper 12. The embodiment shown inFIG. 2 assists in conveying light material from theharvesting machine outlet 30 to theinlet 32 of theblower 14. Theinlet 24 to thefan 22 may be coincident with the center of theblower 14, or located near theblower 14 such that any airflow will assist material movement in the direction of theblower 14. For purposes of explanation, it is to be understood that a material is considered heavy if it has a low surface area to density ratio such that it is likely to be unaffected by an airstream. Stalks, corn cobs, and pebbles are examples of heavy materials. A material is considered light if it has a relatively high surface area to density ration. This material is likely to be displaced by an airstream. Chaff, corn husks, and feathers are examples of light materials. - During biomass harvesting operations, the
fan 22 may assist pulling material into the area of the blower paddles 40 where the heavier material will be picked up by thepaddles 40 and conveyed onwards towards thechute 16 while the lighter material is conveyed with the air. Thefan 22 assists in evacuating air from the back end of thecombine 10. Thus, the fan creates a low pressure area which helps pull material and dust through the machine. In addition, thefan 22 provides a source of air which may be used for further fractionation of light material from heavy material. An example can be separation of lighter non-grain material from heavier non-grain material. For instance heavier non-grain material like cobs (or substantial pieces of cobs) can be conveyed toblower 14 while lighter non-grain material like chaff, dust, and lighter debris or plant material can be aspirated byfan 22 by drawing the lighter non-grain material (e.g. chaff and dust), and separating it from heavier non-grain material (e.g. cobs), which continues toblower 14. The aspirated material can be carried by air flow generated byoutlet 28. This is one way to achieve cob separation from lighter debris. - In addition to the specific configuration shown in
FIG. 2 , the present invention contemplates that theair inlet 24 may be located in various positions including positions which allow the air inlet to provide for intake of ambient air, before thechopper 12, or to provide for air intake from the cleaning shoe area or other vents of thecombine 10 Likewise, theair outlet 28 from thefan 22 for cross aspiration is shown after theblower 14. However, the crossaspiration air outlet 28 could be in a number of different configurations such as, without limitation, after thechopper 12, between thechopper 12 and theblower 14, or elsewhere. -
FIG. 3 illustrates an alternative location for theair inlet 24 and theair outlet 28. InFIG. 3 , the air inlet is before the chopper at thecleaning shoe 26. Theair outlet 28 is after thechopper 12 and before theblower 14. -
FIG. 4 is a diagram showing basic flow of material other than grain (MOG) and how air may be drawn into the fan from various locations and aspirated to various locations. The particular placement of theair inlet 24 and theair outlet 28 may be determined based upon the desired objectives and attendant design considerations. - For example, where a desired objective is to keep the cleaning
shoe 26 of the combine clean, thefan 22 may have itsair inlet 24 placed nearer thecleaning shoe 26 to provide for removal of air from the cleaningshoe 26. This may be achieved whether the combine is operating conventionally or for biomass collection. The cleaningshoe 26 may include a perforated screen which uses a stream of air to lift and fluidize the bed of crop material including grain and material other than grain (MOG). In this manner, the grain, being denser, falls through the screen while the MOG is carried over the screen and out the back of the harvesting machine. Modern harvesting machines have gained so much capacity that the evacuation of this air from the rear of the harvesting machine can be challenging. In fact, modern combines may flow more than 16,000 cubic feet per minute (CFM) through the cleaning shoe. When the stream of air is reduced, the fluidization breaks down and MOG falls through the screen, contaminating the grain sample. The addition of biomass harvest further complicates the matter as the additional machinery provides a restriction to airflow. Thus, thefan 22 may have its air inlet placed after thecleaning shoe 26 to assist in air flow by evacuating air from the harvesting machine. Having one ormore fans 22 creating negative pressure at the outlet may increase the combine efficiency for conventional combines, or combines used in biomass harvest. - Where the desired objective is dust control, placement of the
air inlet 24 of thefan 22 to evacuate air from the combine may be performed. Dust control is a challenge with modern combines flowing massive amounts of air. A restriction at the exit of the combine will cause a pressure build-up in thecleaning shoe 26. This pressure buildup may manifest itself as dust blowing out of the feeder house entrance. Havingfans 22 creating negative pressure at theoutlet 28 reduces dusting from other areas of the combine, and concentrates dust at the exit for better control. Thus dust and dusting out of the feeder house at the front of machine is controlled, thereby improving visibility from the front. - Where the desired objective is to provide for enhanced flow of chopped crop residue from the
chopper 12 to thecrop blower 14, thefan 22 may be placed at thechopper 12 or between thechopper 12 and theblower 14 to induce air flow. Such a placement may also be used to provide for fractionation of biomass into light and heavy fractions in the field and on the go. One of the existing concerns with biomass is the selective harvest of corn cobs. The primary contaminant in corn cobs coming out of thecleaning shoe 26 is husk. Thefans 22 allow a double advantage by both sucking husks out and providing a source of air for further blowing husks out. The exhaust of thefans 22 can be used to increase the acceleration of light crop residues for improved delivery to the in field container such as a truck or wagon. - Thus, the
fan 22 may haveair inlets 24 orair outlets 28 at different positions depending upon the specific objectives to be achieved as thefan 22 has several purposes. The induced air flow from the harvesting machine body to thefan 22 will improve cleaning shoe function by reducing static air pressure inside the combine overall. In biomass harvest, the airflow will assist crop flow from thechopper 12 to thecrop blower 14 or other location where the air inlet is positioned. Secondly, the exhaust air from thefan 22 can be used to aspirate the accelerated crop residue before delivery to the support vehicle (or other container) or the exhaust air can be utilized to enhance the flow of the crop residue to thesupport vehicle 50 shown inFIG. 5 . Thesupport vehicle 50 may be a wagon or truck which includes or forms acollection container 52. - It is further believed that many of the problems associated with conventional combines are the result of improper airflow. The present invention assists with addressing those problems through allowing for various placements of the air inlet of fans and the outlets of the fans. Thus, fans may be added to help cope with the loss of airflow accompanying the modifications to allow biomass harvest. In addition, the proper addition of fans offers advantages for conventional harvest.
- Therefore, advantages associated with the present invention may include assisting in conveying light material from combine outlet to inlet of the blower, assisting in fractionation of plant material, assisting in combine efficiency by evacuating air from the cleaning shoe thus allowing the crop mat to maintain a fluidized bed, controlling dust, conveying light material, assisting in further fractionating heavy and light material downstream from the blower through aspiration, and other advantages.
- Therefore, an improved combine has been disclosed. The present invention contemplates numerous variations in the number, type, and placements of a fan, its inlets, and its outlets. The present invention contemplates variations and alternatives in the manner in which the fan is used to affect air flow in either conventional or biomass harvesting applications both with respect to the air inlet and the aspiration. The present invention is not intended to be limited to the specific embodiments provided herein.
