Abstract
Description
- The present invention relates generally to agricultural combines. It relates particularly to axial-flow, rotary combines and the feeding of crop material from the combine's header assembly to its rotary threshing assembly.
- In the Ricketts et al. U.S. Pat. No. 5,368,522, assigned to the same assignee as the present invention, a combine is described wherein the rearwardmost extremity of a rotating feeder element is placed from 5 to 16 inches, and preferably about 7 inches, from the forwardmost extremity of the impeller blade or blades on a rotary threshing assembly. In the instances where a feeder assembly includes a rotary beater feeder element between the impeller blades and the rearwardmost sprocket member of a feeder conveyor, the axis of rotation of the beater is forward of the pivot axis which connects the feeder housing to the combine frame.
- The afore-described arrangement was thought to provide the optimum relationship of components for highly effective crop feeding to the rotary threshing assembly. The applicant has now designed an improvement on that arrangement, however.
- It is an object of the present invention to provide an improvement in an agricultural combine.
- It is another object to provide an improvement in an agricultural combine which substantially eliminates problems normally encountered in transitioning a crop material mat from feeder elements to rotor elements.
- The foregoing and other objects are realized in a combine feeder assembly and rotor interface including a feeder housing having a front section and a rear section, interconnected in a pivot axis. The front section contains an elongated conveyor. The rear section contains a beater. The rearmost extremity of the beater is spaced from 5 to 16 inches and preferably about 7 inches from the forwardmost extremity of the impeller blade or blades on the front end of the rotor in the axial-flow threshing assembly.
- The invention, including its construction and method of operation, is illustrated more or less diagrammatically in the drawings, in which:
- FIG. 1 is a side elevational view, partly in section of an axial-flow combine incorporating the improved combination of feeder, threshing rotor and chassis or frame of the invention; and
- FIG. 2 is an enlarged side elevational view, partly in section of the improved combination seen in FIG. 1.
- Referring now to the drawings, and particularly to FIG. 1, there is shown a self-propelled
rotary combine 10. Thecombine 10 includes aframe 12 supported by front wheels 14 (the rear wheels are not shown). Anoperators cab 18 is mounted on theframe 12 over thewheels 14. - The
combine 10 is operatively powered by an engine (not shown), suitably supported on theframe 12. The transfer of power from the engine to various driven components of the combine is conventional in nature and could include fixed, variable belt or chain drives which are not shown or described but are well known in the art. - At its front end, the
combine 10 is provided with a cropharvesting header assembly 20 for severing and gathering crop materials. Theheader assembly 20 cuts and directs crop materials toward acrop feeder assembly 22 including aconveyor 24. Theconveyor 24 moves crop materials in a crop layer or mat toward a rotary threshingassembly 28 which threshes the grain from materials other than grain. - The
threshing assembly 28 is supported in a conventional manner on theframe 12 of thecombine 10 and embodies crop threshing and separating means in a single unit. More specifically, theassembly 28 includes a generally tubular rotor casing orhousing 30 mounted in a fore-and-aft direction on theframe 12 of thecombine 10. A generallycylindrical rotor 31 is arranged coaxially within thecasing 30. Therotor 31 has a plurality ofthreshing elements 32 mounted circumferentially around, and longitudinally along, its outer surface. - At its forward end, the
rotor 31 includes animpeller blade sub-assembly 34 for drawing air and crop materials into and through therotary threshing assembly 28. Theimpeller blade sub-assembly 34 includes a plurality of substantiallyidentical impeller blades 36 which are secured to therotor 31 and are equally spaced relative to each other. Theimpeller blades 36 of theimpeller sub-assembly 34 may take different shapes, depending upon the particular manufacturer and other criteria. Nevertheless, eachimpeller blade 36 has a leadingedge 38 which lies in a plane extending generally normal to the rotational axis of therotor 31. As will be appreciated, upon rotation ofrotor 31, theimpeller blade sub-assembly 34 also rotates. - Referring now to FIG. 2, as well as FIG. 1, the
feeder assembly 22 includes ahousing 39 having afront section 40 which encloses theconveyor 24 and arear section 41. Thehousing section 40 includes a pair ofsidewalls bottom walls 46 and 48 respectively. Thesidewalls - The
feeder housing section 40 is joined at a forward end 49 to the cropharvesting header assembly 20. Toward a rear end, thefeeder housing section 40 is pivotally connected to the feeder housingrear section 41 on a pivot axis A. Therear section 41 is rigidly connected to theframe 12. Thefeeder housing section 40, with the cropharvesting header assembly 20 affixed to the forward end thereof, is vertically movable about the axis A by a hydraulic cylinder 52 selectively operable from the operator station 16. - The
conveyor 24 of thefeeder assembly 22 receives crop materials from the cropharvesting header assembly 20 at a forward end and discharges the crop materials at a rearward end. Theconveyor 24 includes a plurality of transversely spaced, endless chains 54 having a series of elongated slats or crossbars 56 which span the distance between the chains 54. The slats 56 are connected in a conventional manner to the chains 54, so as to be driven thereby. - The endless chains54 are entrained for orbital rotation about a pair of longitudinally spaced, rotatable chain supports 58 and 61. In the illustrated embodiment, rotatable chain support 58 defines a rotary-drive including a plurality of laterally spaced sprockets 57 (only one shown) secured along the length of a driven shaft 59. The shaft 59 is supported on the axis A by the respective sidewalls of the
feeder housing section 40. Securing all thesprockets 57 to a common drive shaft ensures that the chains 54 will be driven in unison relative to each other. The rotatable chain support 61 serves as an idler. - According to the invention, the
feeder assembly 22 includes a stone trap 62 provided in the housingrear section 41 between the discharge end of theconveyor 24 and therotor assembly 28, to inhibit the introduction of foreign articles such as stones, rocks, or the like into the threshing area. The stone trap 62 includes a rotary drivenbeater 66 arranged in a cooperative relationship with astone receiving trough 68. Thebeater 66 includes a plurality of radial blades or vanes 70. The drivenbeater 66 is supported at opposite ends in therear section 41 for rotation about transverse axis B. - During operation of the
combine 10, unthreshed crop materials are moved rearwardly in a linear fashion between theconveyor 24 and thebottom wall 48 of thefeeder housing 40. As the crop materials move rearwardly, they are generally in the form of a cohesive sheet or mat. The crop materials are linearly driven toward therotor assembly 28 as the chains 54 orbit around thesprockets 57 of the chain support 58. - The crop materials are discharged onto the beater62. If the crop layer or mat of unthreshed crop materials contains any foreign articles having a mass, such as small stones or rocks, the vanes 70 of the
beater 66 engage them and forcibly drive them into thetrough 68, thereby preventing their introduction into the rotor assembly. - According the present invention, the transverse axis B of the
beater 66 is longitudinally displaced upstream (rearwardly) of the transverse pivotal axis A about which theheader assembly 20 vertically moves. It is been found that providing a transitional area of 5 to 16 inches between the discharge end of thefeeder assembly 22 and the leading edge or forwardmost extremity of theimpeller blade assembly 34 allows the movement of crop materials to translate smoothly from a linear flow imparted to the materials by thefeeder assembly 22 to a rotary or circulatory flow imparted to the materials by theimpeller blades 36 of theimpeller blade assembly 34. In the preferred form of the invention, the transitional spacing between the rearwardmost extremity of the vanes 70 in thebeater 66 of thefeeder assembly 22, and a leading edge or forwardmost extremity of theimpeller blade assembly 34, is about 7 inches. - While a preferred embodiment of the invention has been described, it should be understood that the invention is not so limited, and modifications may be made without departing from the invention. The scope of the invention is defined by the appended claims, and all devices that come within the meaning of the claims, either literally or by equivalence, are intended to be embraced therein.
