(1) Field of the Invention
The disclosure relates to shield devices and more particularly pertains to a new shield device for inhibiting grain from being spilled over a sweep auger in a grain bin. The device includes a back shield that is mounted to a sweep auger and an extension shield that is mountable to the back shield. In this way the extension shield increases the overall height of the back shield. Thus, the extension shield deflects grain back into the sweep auger that would otherwise pass over the back shield. In this way the grain does not collect on the floor of the grain bin while the sweep auger is collecting the grain.
(2) Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 1.98.
The prior art relates to shield devices including a grain screen that is integrated into a feeder chute of a grain harvester. The prior art discloses a foraminous screen for a peanut harvester. The prior art discloses a legume harvester that includes a series of augers and chutes for harvesting legumes. The prior art discloses a concave pan that is mountable beneath a conveyor of a grain harvester for collecting tailings from grain harvesting. The prior art discloses a thresher separator for a combine harvester that includes a foraminous drum.
An embodiment of the disclosure meets the needs presented above by generally comprising a sweep auger that has a back shield which is coupled to the sweep auger. An extension shield is provided that is mountable to the back shield of the sweep auger. Thus, the extension shield increases the overall height of the back shield. In this way the extension shield inhibits grain from passing over the back shield when the sweep auger is removing grain from a floor of a grain bin.
There has thus been outlined, rather broadly, the more important features of the disclosure in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
The extension shield 22 has a first end 24 and a second end 26, and the extension shield 22 is elongated between the first end 24 and the second end 26. The extension shield 22 has a front surface 28 extending between the first end 24 and the second end 26, and the extension shield 22 has a back surface 30 extending between the first end 24 and the second end 26. Additionally, the extension shield 22 has a bottom edge 32 extending between the first end 24 and the second end 26, and the extension shield 22 has a top edge 34 extending between the first end 24 and the second end 26. The extension shield 22 is comprised of a rigid material, such as steel or the like, to deflect grain 19 that is swept by the sweep auger 12. The extension shield 22 may have a length ranging between approximately 40.0 inches and 50.0 inches and the extension shield 22 may have a height ranging between approximately 5.0 inches and 7.0 inches.
The extension shield 22 has a first bend 36 extending between the first end 24 and the second end 26 to define a first mounting portion 38 and a second mounting portion 40 that are oriented at an angle with each other. The first bend 36 is spaced from the bottom edge 32 and the first bend 36 is oriented parallel to the bottom edge 32. Each of the first mounting portion 38 and the second mounting portion 40 may have a width of approximately 0.75 inches. The extension shield 22 has a second bend 42 extending between the first end 24 and the second end 26 to define a medial portion 44 forming an angle with the second mounting portion 40. The second bend 42 is oriented parallel with the first bend 36 and the medial portion 44 lies on a plane that is oriented parallel with the first mounting portion 38. The medial portion 44 is spaced rearwardly from the first mounting portion 38 such that the second mounting portion 40 extends between the first mounting portion 38 and the medial portion 44. Furthermore, the medial portion 44 may have a height of approximately 4.0 inches.
The extension shield 22 has a third bend 46 extending between the first end 24 and the second end 26 to define an upper portion 48 forming an angle with the medial portion 44. The third bend 46 is oriented parallel with the second bend 42. Additionally, the upper portion 48 lies on a plane that is oriented parallel with the second mounting portion 40 having the upper portion 48 extending forwardly from the medial portion 44. The upper portion 48 may have a width of approximately 1.0 inches.
The extension shield 22 has a fourth bend 50 extending between the first end 24 and the second end 26 to define an angled portion 52 forming an angle with the upper portion 48. The angled portion 52 angles away from the medial portion 44 such that the top edge 18 of the extension shield 22 is directed downwardly toward the bottom edge 32 of the extension shield 22. The extension shield 22 has a plurality of mounting holes 54 each extending through the front surface 28 and the back surface 30 of the extension shield 22. Each of the mounting holes 54 is positioned on the first mounting portion 38 and the mounting holes 54 are spaced apart from each other and are distributed between the first end 24 and the second end 26.
The back surface 30 corresponding to the first mounting portion 38 rests against the forward surface 20 of the vertical portion 16 of the back shield 14 on the sweep auger 12 such that the top edge 18 of the vertical portion 16 abuts the second mounting portion 40. Moreover, the medial portion 44 lies on a plane that is oriented parallel with the vertical portion 16 of the back shield 14 such that the angled portion 52 of the extension shield 22 is directed toward the sweep auger 12. In this way the medial portion 44 deflects grain 19 that is directed rearwardly from the sweep auger 12. Additionally, the angled portion 52 of the extension shield 22 deflects grain 19 that is directed upwardly from the sweep auger 12. Each of the medial portion 44 and the angled portion 52 defines a barrier 58 to inhibit grain 19 that is directed rearwardly from the sweep auger 12 from collecting on the floor 23 of the grain bin 21. In this way the sweep auger 12 can more efficiently sweep the grain 19 from the floor 23 of the grain bin 21 such that the grain 19 is inhibited from making the floor 23 unsafe to walk upon.
A plurality of fasteners 60 is provided and each of the fasteners 60 is extendable through a respective one of the mounting holes 54. Each of the fasteners 60 engages the vertical portion 16 of the back shield 14 for attaching the extension shield 22 to the back shield 14. Additionally, each of the fasteners 60 may comprise a nut and a bolt or other type of releasable, mechanical fastener. In an alternative embodiment 62 as is most clearly shown in
In use, the extension shield 22 is mounted to the back shield 14 of the sweep auger 12. In this way the extension shield 22 deflects grain 19 back into the sweep auger 12 that would otherwise pass over the back shield 14 and collect on the floor 23 of the grain bin 21. Thus, the sweep auger 12 can more efficiently remove the grain 19 from the floor 23 of the grain bin 21. Moreover, the extension shield 22 inhibits the grain 19 that would otherwise pass over the back shield 14 from making walking on the floor 23 of the grain bin 21 unsafe for a worker that is supervising the operation of the sweep auger 12. In this way the worker can safely walk on the floor 23 of the grain bin 21 without falling down and potentially being injured by the sweep auger 12.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, 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, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure 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 the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
