Description
TITLE OF THE INVENTION:
Flow Control Apparatus For a Grain Auger NAMES) OF INVENTOR(S):
Eric Allen Klein FIELD OF THE INVENTION
The present invention relates to a flow control apparatus for a grain auger.
BACKGROUND OF THE INVENTION
There are a number of flow control problems associated with grain augers. A grain auger requires a minimum depth of grain in order to operate. When the grain storage bin is substantially empty the grain auger is unable to operate and the farmer must remove whatever grain remains manually using a shovel.
When a grain auger is turned off, a substantial quantity of grain remains in the grain auger. The larger the grain auger, the greater the quantity of grain. This quantity of grain sometimes makes it impossible to move the grain auger without first unloading the accumulated grain. When there is not a transport vehicle or storage container available into which the accumulated grain can be discharged, the grain must be discharged onto the ground.
United States Patent 5,845,762 which issued to Stark in 1998 proposes a potential solution to the first problem. The Stark patent reference discloses an "auger boot" which has an grain accumulator and a grain hopper. The auger boot is placed over a feed end of an auger. Grain is shovelled into the grain hopper which, in turn, supplies grain to the grain accumulator.
The grain accumulator accumulates a sufficient quantity of grain to enable the grain auger to operate. The Stark patent reference does not propose any solution to the second problem described above.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The preferred embodiment, a flow control apparatus for a grain auger, generally identified by reference numeral 10, will now be described with reference to FIGURES 1 through 4.
Although apparatus 10 will be described with reference to augering of grain, it will be recognized that apparatus 10 will also be useful for augering granular or finely divided materials other than grain.
Referring to FIGURE 1, flow control apparatus 10 includes a body 12. Referring to FIGURES 3 and 4, flow control apparatus 10 has an auger receiving channel 14 into which an auger 16 can be received. Body 12 has an open first end 18 communicating with auger receiving channel 14 and an open second end 20 communicating with auger receiving channel 14.
Body 12 has projecting tabs 22 that extend from first end 18 parallel to auger receiving channel 14. Projecting tabs 22 have pin receiving apertures 24. An end closure 26 is pivotally mounted by a hinge 28 to first end 18 of body 12.
End closure 26 has tab receiving slots 54, which receive projecting tabs 22 as will hereinafter be further described.
A handle 34 is secured to an external surface 36 of body 12, for use in moving body 12 relative to auger 16. Flow control apparatus 10 has flanges 30 which extend upwardly and outwardly from opposed upper peripheral edges 32 of auger receiving channel 14.
Flow control apparatus 10 has two operating modes. The first of the two operating modes is illustrated in FIGURES 1 and 2. Flow control apparatus 10 is movable laterally along a length of auger 16 between a disengaged position in which body 12 is distanced from a working end 41 of auger 16, illustrated in FIGURE 1, and a covering position in which body 12 covers working end 41 of auger 16, illustrated in FIGURE 2. Referring to FIGURE 1, when grain is to be augered, apparatus 10 is distanced from an opening 40 at working end 41 of auger 16.
The preferred embodiment, a flow control apparatus for a grain auger, generally identified by reference numeral 10, will now be described with reference to FIGURES 1 through 4.
Although apparatus 10 will be described with reference to augering of grain, it will be recognized that apparatus 10 will also be useful for augering granular or finely divided materials other than grain.
Referring to FIGURE 1, flow control apparatus 10 includes a body 12. Referring to FIGURES 3 and 4, flow control apparatus 10 has an auger receiving channel 14 into which an auger 16 can be received. Body 12 has an open first end 18 communicating with auger receiving channel 14 and an open second end 20 communicating with auger receiving channel 14.
Body 12 has projecting tabs 22 that extend from first end 18 parallel to auger receiving channel 14. Projecting tabs 22 have pin receiving apertures 24. An end closure 26 is pivotally mounted by a hinge 28 to first end 18 of body 12.
End closure 26 has tab receiving slots 54, which receive projecting tabs 22 as will hereinafter be further described.
A handle 34 is secured to an external surface 36 of body 12, for use in moving body 12 relative to auger 16. Flow control apparatus 10 has flanges 30 which extend upwardly and outwardly from opposed upper peripheral edges 32 of auger receiving channel 14.
Flow control apparatus 10 has two operating modes. The first of the two operating modes is illustrated in FIGURES 1 and 2. Flow control apparatus 10 is movable laterally along a length of auger 16 between a disengaged position in which body 12 is distanced from a working end 41 of auger 16, illustrated in FIGURE 1, and a covering position in which body 12 covers working end 41 of auger 16, illustrated in FIGURE 2. Referring to FIGURE 1, when grain is to be augered, apparatus 10 is distanced from an opening 40 at working end 41 of auger 16.
With flow control apparatus 10 out of the way, grain can flow freely into opening 40 at working end 41 of auger 16. The grain is then carried by auger flighting 44 along an interior passage 42 of auger 16. When a truck into which grain is being loaded is close to being full it is desirable to stop the flow of grain. Simply stopping rotation of auger flighting 44 will stop the flow of grain, but will leave auger 16 full of grain.
When auger 16 is full of grain it is difficult, if not impossible to move. Referring to FIGURE 2, when it is desired to shut off the flow of grain, rotation of auger flighting 44 is maintained and flow control apparatus 10 is moved laterally along auger 16 to the covering position with body 12 covering opening 40. The positioning of body 12 of flow control apparatus 10 over opening 40 prevents further grain from entering auger 16. The continued rotation of auger flighting 44 enables grain to be emptied from auger 16.
The second of the two operating modes is illustrated in FIGURES 3 and 4. When a granary has been substantially emptied, a residual amount of grain remains on the floor of the granary which cannot be picked up by auger 16. The residual amount of grain must be moved manually using a shovel. By repositioning flow control apparatus 10, the task of removing the residual amount of grain is made easier as flow control apparatus 10 can be used with auger 16. Flow control apparatus 10 is resituated on auger 16 so that first end 18 of flow control apparatus 10 is positioned at working end 41 of auger 16. Flow control apparatus 10 is positioned so that opening 40 is uncovered and flanges 30 extend in an upward and outward direction on each side of opening 40. Referring to FIGURE 3, end 41 of auger 16 is closed by pivotally moving end closure 26 to cover end 41, as shown by curved arrow 56. End closure 26 is secured in position by inserting projecting tabs 22 into tab receiving slots 54 of end closure 26 and then inserting locking pins 58, as indicated by dotted lines 60, to prevent tabs 22 from being withdrawn from tab receiving slots 54.
Referring to FIGURE 4, with end closure closed, the residual amount of grain in the Brainier can then be shovelled into auger receiving channel between flanges 30 and end closure 26, and thus is fed into opening 40 of auger 16. A spring 50 extends between hooks 52 on flanges 30 at second end 20. This 5 helps prevent auger receiving channel 14 from spreading as it becomes filled with grain and helps hold flow control apparatus in position on auger 16.
It will be apparent to one skilled in the art that 10 modifications may be made to the illustrated embodiment without departing from the spirit and scope of the invention as hereinafter defined in the Claims.
When auger 16 is full of grain it is difficult, if not impossible to move. Referring to FIGURE 2, when it is desired to shut off the flow of grain, rotation of auger flighting 44 is maintained and flow control apparatus 10 is moved laterally along auger 16 to the covering position with body 12 covering opening 40. The positioning of body 12 of flow control apparatus 10 over opening 40 prevents further grain from entering auger 16. The continued rotation of auger flighting 44 enables grain to be emptied from auger 16.
The second of the two operating modes is illustrated in FIGURES 3 and 4. When a granary has been substantially emptied, a residual amount of grain remains on the floor of the granary which cannot be picked up by auger 16. The residual amount of grain must be moved manually using a shovel. By repositioning flow control apparatus 10, the task of removing the residual amount of grain is made easier as flow control apparatus 10 can be used with auger 16. Flow control apparatus 10 is resituated on auger 16 so that first end 18 of flow control apparatus 10 is positioned at working end 41 of auger 16. Flow control apparatus 10 is positioned so that opening 40 is uncovered and flanges 30 extend in an upward and outward direction on each side of opening 40. Referring to FIGURE 3, end 41 of auger 16 is closed by pivotally moving end closure 26 to cover end 41, as shown by curved arrow 56. End closure 26 is secured in position by inserting projecting tabs 22 into tab receiving slots 54 of end closure 26 and then inserting locking pins 58, as indicated by dotted lines 60, to prevent tabs 22 from being withdrawn from tab receiving slots 54.
Referring to FIGURE 4, with end closure closed, the residual amount of grain in the Brainier can then be shovelled into auger receiving channel between flanges 30 and end closure 26, and thus is fed into opening 40 of auger 16. A spring 50 extends between hooks 52 on flanges 30 at second end 20. This 5 helps prevent auger receiving channel 14 from spreading as it becomes filled with grain and helps hold flow control apparatus in position on auger 16.
It will be apparent to one skilled in the art that 10 modifications may be made to the illustrated embodiment without departing from the spirit and scope of the invention as hereinafter defined in the Claims.
