Description
21~S~389 CLEANING SHOE ADJUSTMENT MECHANISM
BACKGROUND OF THE INVENTION
1. Field of the Invention:
The invention is directed to an adjustment mechanism for adjusting the louvers in a cleaning shoe from outside the sidesheets of the combine's supporting structure.
BACKGROUND OF THE INVENTION
1. Field of the Invention:
The invention is directed to an adjustment mechanism for adjusting the louvers in a cleaning shoe from outside the sidesheets of the combine's supporting structure.
2. Description of the Prior Art:
Typically, after threshing and separation, some chaff and straw are still mixed with the grain; the cleaning assembly removes this trash from the grain. In most combines, the cleaning assembly comprises three major components: a cleaning fan, a chaffer and a sieve. The cleaning fan has its own housing, whereas the chaffer and sieve are mounted to the cleaning shoe.
The cleaning fan is a multi-bladed fan located in front of the cleaning shoe. The air blast from the fan removes most of the chaff and straw from the grain by blowing it out the rear of the combine. The air blast can be regulated by adjusting fan speed or by changing the fan opening.
The cleaning shoe, which contains the chaffer and sieve, is mounted to the supporting structure of the combine below the separating assembly. The bottom of the cleaning shoe contains the tailings auger and the clean grain auger.
The chaffer and sieve are suspended on hangers attached to the sides of the cleaning shoe. There are three types of typical shoe action, reciprocating, shaking and cascading. In the reciprocating shoe the chaffer and sieve move in opposite directions to one another. In the shaking shoe the chaffer and the sieve move in the same direction. In the cascading shoe the chaffer and sieve are arranged so that the material drops from one unit to another in a cascading or rolling motion.
Chaffers are either adjustable or non-adjustable. The adjustable chaffer is made up of a series of transversely extending louvers with rows of teeth. Each of these louvers is mounted on a crank shaft having a crank arm that engages an 2145~9 axially extending adjusting bar. By axially moving the adjusting bar all of the louvers are moved simultaneously.
The two most common sieves are the adjustable louver type, which is similar to the chaffer with smaller openings, and the non-adjustable round-hole type.
The adjustable chaffer and sieve are adjusted in response to crop conditions. The louvers of the chaffer are opened or closed just enough so that the grain falls through the chaffer before passing the length of the chaffer. If the chaffer is opened to wide, it may overload the sieve with chaff. If the chaffer is not opened wide enough, excess grain will be directed to the tailings auger and some will be lost out the rear of the combine. The louvers of the sieve must be opened far enough to allow kernels of grain to fall through easily, but not so far that straw and chaff are allowed to drop through.
Presently an operator must crawl into the back of the combine between the sidesheets to make these adjustments.
This makes these adjustments cumbersome and time consuming.
SUMMARY
It is an object of the present invention to provide a simple adjustment mechanism for adjusting the louvers on the chaffer and the sieve of the cleaning shoe from outside the sidesheets of the combine.
The present invention is directed to a the sieve assembly which comprises the chaffer and sieve. Both the chaffer and sieve are provided with a plurality of transversely extending louvers. Each louver is provided with a crank shaft having a crank arm for adjusting the angular orientation of the louver.
The crank arms are received in slots formed in an axially extending adjusting bar. By moving the adjusting bar axially fore and aft the angular position of the louvers and thereby their openings are changed.
In a first embodiment, the adjusting bar is provided with an internally threaded member that engages the externally threaded portion of an axially arranged rotatable shaft. The axially arranged rotatable shaft is provided with an axial 211~889 bevel gear that meshes with a perpendicular transverse bevel gear that is mounted to a transversely arranged rotatable shaft. The transversely arranged rotatable shaft is provided with an end remote from the transverse bevel gear having an engagement handle for rotating the rotatable shafts. The engagement handle is located adjacent to a hole formed in the left sidesheet of the supporting structure of the combine.
The engagement handle comprises a pin extending through the transversely arranged rotatable shaft. The handle is engaged by a tool having two slots for engaging the pin and rotating the shaft.
In another preferred embodiment, a non-rotatable shaft having an externally threaded portion is mounted to the adjusting bar. The threaded portion of the non-rotatable shaft engages the internally threaded portion of the axial bevel gear to move the adjusting bar fore and aft axially in the combine.

DETAILED DESCRIPTION
Figure 1 is the side view of a self-propelled agricultural combine 10. The combine comprises a supporting structure 12 having wheels 14 supporting the frame. The supporting structure comprises two axially extending sidesheets between which are located the various processing assemblies. Extending forwardly from the combine is a harvesting platform 16 which directs a harvested crop to feederhouse 18. The feederhouse is a conveyor for directing the harvested crop material to the threshing, separating and cleaning assemblies located within the sidesheets of the combine. Although the present invention is disclosed as being 21458~9 mounted on a axial combine it may also be used on conventional and other combine configurations having a cleaning shoe.
In the illustrated combine, the feederhouse 18 directs the harvested crop to a transverse beater 20 which propels the crop material through an inlet transition section 22 to an axial threshing and separating assembly 24. Grain and chaff are directed from the axial threshing and separating assembly 24 to cleaning assembly 26. The cleaning assembly in turn directs the clean grain to grain tank 28 and the chaff is blown out the rear of the combine by cleaning fan 30. Crop material other than grain and chaff is directed by the axial separating unit to transverse beater 32 which propels this material out the rear of the combine. Clean grain temporarily stored in grain tank 28 can be unloaded by an operator in operator's cab 34 actuating unloading auger 36. The threshing and separating assembly and the cleaning assembly are located between the sidesheets of the supporting structure.
The present invention is directed to a mechanism for adjusting the louvers in the cleaning shoe from the side of the combine. The cleaning shoe 38 is provided with a chaffer 40 and a sieve 42. The chaffer and sieve are provided with transverse adjustable louvers 44, best shown in Figure 4, which are mounted in a rectangular frame that is secured to the sidewalls of the cleaning shoe. Each of the louvers is provided with a crank shaft 46 having a crank arm 48. The crank arm 48 is positioned in slot 50 of axial adjusting bar 52. By moving the adjusting bar axially the angular orientation of all the louvers in the chaffer or all the louvers in the sieve can be adjusted. The adjusting bar 52 is housed in an axially extending inverted U-shaped housing 53.
The adjusting bar 52 is attached to internally threaded member 54 by strap 56. Threaded member 54 is mounted to the threaded portion 57 of axially arranged rotatable shaft 58.
Rotatable shaft 58 is provided with an axial bevel gear 60.
The axial bevel gear 60 is located in inverted U-shaped channel 62. The channel 62 forms the end wall of the chaffer and/or sieve. The rotatable shaft 58 extends through both end walls 64 to prevent the shaft from twisting.
Perpendicular transverse bevel gear 66 meshes with axial bevel gear 60 and is mounted to transversely arranged rotatable shaft 68. A series of web members 70 extend across the channel 62 to prevent the rotatable shaft 68 from twisting therein. Rotatable shaft 68 extends transversely approximately halfway across the interior of the supporting structure defined by the sidesheets. This rotatable shaft 68 terminates in an end 72 that is located adjacent to either chaffer openings 74 or sieve opening 76 located in the sidesheets of the supporting structure of the combine. End 72 is provided with an engagement handle 76 comprising a pin 78 which is inserted through the rotatable shaft 68.
An operator in adjusting the chaffer and/or sieve uses a tool having two slots that engage the pin 78. The tool is provided with a crank for rotating the rotatable shaft 68 and thereby adjusting the chaffer and/or sieve. This engagement arrangement is similar to the engagement arranged disclosed in U.S. Patent 4,969,853 for removing an axial separator module.
In another preferred embodiment, a non-rotatable shaft having an externally threaded portion is mounted to the adjusting bar. The threaded portion of the non-rotatable shaft engages an internally threaded portion of the axial bevel gear to move the adjusting bar fore and aft axially in the combine. The transverse bevel gear, the transverse rotatable shaft and the engagement handle remain the same.
It should be noted that the externally threaded portion of the non-rotatable shaft constitutes a threaded member similar to the threaded member 54 which cooperates with the axial bevel gear to drive the adjusting bar in an axial direction.
The present invention should not be limited by the above-described embodiment, but should be limited solely by the claims that follow.

DETAILED DESCRIPTION
Figure 1 is the side view of a self-propelled agricultural combine 10. The combine comprises a supporting structure 12 having wheels 14 supporting the frame. The supporting structure comprises two axially extending sidesheets between which are located the various processing assemblies. Extending forwardly from the combine is a harvesting platform 16 which directs a harvested crop to feederhouse 18. The feederhouse is a conveyor for directing the harvested crop material to the threshing, separating and cleaning assemblies located within the sidesheets of the combine. Although the present invention is disclosed as being 21458~9 mounted on a axial combine it may also be used on conventional and other combine configurations having a cleaning shoe.
In the illustrated combine, the feederhouse 18 directs the harvested crop to a transverse beater 20 which propels the crop material through an inlet transition section 22 to an axial threshing and separating assembly 24. Grain and chaff are directed from the axial threshing and separating assembly 24 to cleaning assembly 26. The cleaning assembly in turn directs the clean grain to grain tank 28 and the chaff is blown out the rear of the combine by cleaning fan 30. Crop material other than grain and chaff is directed by the axial separating unit to transverse beater 32 which propels this material out the rear of the combine. Clean grain temporarily stored in grain tank 28 can be unloaded by an operator in operator's cab 34 actuating unloading auger 36. The threshing and separating assembly and the cleaning assembly are located between the sidesheets of the supporting structure.
The present invention is directed to a mechanism for adjusting the louvers in the cleaning shoe from the side of the combine. The cleaning shoe 38 is provided with a chaffer 40 and a sieve 42. The chaffer and sieve are provided with transverse adjustable louvers 44, best shown in Figure 4, which are mounted in a rectangular frame that is secured to the sidewalls of the cleaning shoe. Each of the louvers is provided with a crank shaft 46 having a crank arm 48. The crank arm 48 is positioned in slot 50 of axial adjusting bar 52. By moving the adjusting bar axially the angular orientation of all the louvers in the chaffer or all the louvers in the sieve can be adjusted. The adjusting bar 52 is housed in an axially extending inverted U-shaped housing 53.
The adjusting bar 52 is attached to internally threaded member 54 by strap 56. Threaded member 54 is mounted to the threaded portion 57 of axially arranged rotatable shaft 58.
Rotatable shaft 58 is provided with an axial bevel gear 60.
The axial bevel gear 60 is located in inverted U-shaped channel 62. The channel 62 forms the end wall of the chaffer and/or sieve. The rotatable shaft 58 extends through both end walls 64 to prevent the shaft from twisting.
Perpendicular transverse bevel gear 66 meshes with axial bevel gear 60 and is mounted to transversely arranged rotatable shaft 68. A series of web members 70 extend across the channel 62 to prevent the rotatable shaft 68 from twisting therein. Rotatable shaft 68 extends transversely approximately halfway across the interior of the supporting structure defined by the sidesheets. This rotatable shaft 68 terminates in an end 72 that is located adjacent to either chaffer openings 74 or sieve opening 76 located in the sidesheets of the supporting structure of the combine. End 72 is provided with an engagement handle 76 comprising a pin 78 which is inserted through the rotatable shaft 68.
An operator in adjusting the chaffer and/or sieve uses a tool having two slots that engage the pin 78. The tool is provided with a crank for rotating the rotatable shaft 68 and thereby adjusting the chaffer and/or sieve. This engagement arrangement is similar to the engagement arranged disclosed in U.S. Patent 4,969,853 for removing an axial separator module.
In another preferred embodiment, a non-rotatable shaft having an externally threaded portion is mounted to the adjusting bar. The threaded portion of the non-rotatable shaft engages an internally threaded portion of the axial bevel gear to move the adjusting bar fore and aft axially in the combine. The transverse bevel gear, the transverse rotatable shaft and the engagement handle remain the same.
It should be noted that the externally threaded portion of the non-rotatable shaft constitutes a threaded member similar to the threaded member 54 which cooperates with the axial bevel gear to drive the adjusting bar in an axial direction.
The present invention should not be limited by the above-described embodiment, but should be limited solely by the claims that follow.
