Abstract
Description
- The present invention relates to the transferring of grain or other particulates, and particularly to the transferring of grain or other particulates from a grain bin or other storage location.
- Grain bins, which generally are in a cylindrical configuration and having a conically shaped roof can be in excess of 40 feet in diameter and in excess of 40 feet in height, storing for example, in excess of 30,000 bushels of grain or other particulate material. The bin floor, for example, may be formed by a poured concrete slab. The bin walls which are securely anchored to the bin floor are generally made of curved, corrugated stainless steel panels which are bolted or joined together to form a continuous curved wall for the bin. An access door at the bottom of the bin is generally provided to allow access for workers and equipment onto the bin floor, for example, when the bin is substantially empty. The roof of the bin will generally have an access hole at the top to allow access for workers and equipment.
- Grain piled against a bin wall will exert outward pressure on the bin wall. It will be appreciated that this force can be significant, and in the case of large grain bins, this force is sufficient to deform bin walls if care is not taken during the grain loading and unloading processes to ensure that the grain is evenly distributed in the bin at all times during the loading and unloading processes. To minimize the risk of deformation, bins are preferably loaded and unloaded from the middle of the bin, to ensure that grain is at all times distributed throughout the bin during the loading and unloading processes, to thereby equalize to the extent possible the loading on the bin walls.
- While loading the bin from a position approximately in the middle of the grain pile is readily achieved by loading the grain into the bin by means of a conveyor, the delivery end of which is positioned at the top center of the bin (for example, when the grain is loaded from a conveyor which discharges the grain through a top access door in the roof of the bin), which conveyor delivery end is equidistant the bin walls, so that when the grain falls to the bin floor a pile is formed which continually expands to the bin walls to substantially evenly distribute the grain in the bin and as the pile continues to grow, to substantially evenly load the bin walls. This allows the outward pressure on any portion of the wall of the bin to be offset and balanced by the outward pressure on that portion of the wall of the bin which is directly opposite that portion.
- During the removal of grain from the bin, continuously unloading the bin from the center of the grain pile, while necessary to minimize the risk of deformation of the bin wall, is more difficult.
- Accordingly, one object of the present invention is to provide an improved device and method for transferring grain or other particulates from a grain bin.
- Another object of the present invention is to provide an improved device and method for effectively providing for the transfer of grain or other particulates from a grain bin, while minimizing the loading on the bin walls, and thus reducing the risk of deformation of the bin wall during the loading and unloading processes.

- According to another aspect of the present invention, there is provided a method of transferring grain from a grain bin having an interior for holding a quantity of grain, the method comprising positioning an inlet and an outlet in opposed sidewalls of the grain bin; inserting a grain transfer tube through each of the inlet and the outlet so as to be positioned substantially within the interior of the grain bin, the grain transfer tube having at least one opening therein for permitting grain in the grain bin to enter into an interior of the tube; placing at least one blower at an end of the grain transfer tube positioned at the inlet; utilizing the at least one blower to draw an air stream through the grain transfer tube; and attaching a suction hose to the outlet to draw, in combination with the at least one blower, grain in the grain bin into the tube for transferal through the outlet to a remote location.

Thevertical walls 5 and conical roof 6 of the typical grain bin 4 are generally made of corrugated stainless steel or other suitable material, known to a person skilled in the alt. Anaccess door 8 provides access for personnel and equipment into the interior of the grain bin 4 and an access port 10 at the top of the grain bin 4 permits grain to be transferred from aconveyor system 14 into the interior of the grain bin 4 for storage, which typically forms apile 12 generally centered within the grain bin 4. - Referring to
FIG. 2 , ametal tube 16 extends across the concrete pad 2 (or other floor material for the bin, hereinafter referred to as the “concrete pad”), and is securely anchored thereto by means of anchors, straps, bolts or other devices known to a person skilled in the art, so that thetube 16 remains stationary during the grain loading and unloading processes. In the preferred embodiment, the tube is of generally circular cross-section and is made of aluminum, or stainless steel, it being understood that alternative materials and cross-sections may be utilized in alternative embodiments of the present invention.

In the preferred embodiment, theexternal cover 20 is supported by and may slide along an externalhorizontal guideway 26, which may be made of, for example, channel or flat bar welded or otherwise securely fastened to the outside of thetube 16, it being understood that alternative guideways may be utilized to support and permit the movement of theexternal cover 20 between an open and closed position. Ahandle 28, fastened to the external cover, and extending through the exterior wall of the bin may be utilized to move theexternal cover 20 between the open and closed position as needed, it being understood that alternative mechanisms may be utilized to move the external cover between the open and closed position. - As illustrated in
FIGS. 5B and 5C , in one embodiment of the present invention, acoarse screen 30 is provided, and is securely attached to thetube 16 covering theorifice 18, to prevent large objects from entering into thetube 16, the coarseness of the screen being such that it would readily permit grain or other particulates to easily flow therethrough, while at the same time, preventing large objects from passing therethrough. As illustrated inFIGS. 5A, 5B and 5C, the screen is positioned to cover the entire orifice, and in such a manner as to permit theexternal cover 20 to easily slide over the screen between the closed position illustrated inFIG. 5A and the open position illustrated inFIG. 5B without interference between the screen and theexternal cover 20, as illustrated inFIG. 5A . - In an alternative embodiment of the present invention as illustrated in
FIGS. 6 and 7 , anoutlet tube 34 extends beneath or within thepad 2 from an area outside of thebin wall 5, beneath thebin wall 5 to an area near the center of the bin where there is located anopening 36 in theconcrete pad 5, theoutlet tube 34 having anorifice 18 therein substantially corresponding with theopening 36 in theconcrete pad 2, to permit grain or other particulates to flow into theoutlet tube 34 as described herein. Aninlet tube 32 extends from outside of thebin wall 5 on the opposite side of the bin, through thebin wall 5, and extends to an area proximate to theopening 36 in theconcrete pad 2. During non-use, theoutlet tube 34 andinlet tube 32 are both capped withremovable caps 17 to keep varmints, the weather and other materials from accessing thetube 16 and the interior of the grain bin 4. - Referring to
FIGS. 6, 7 , 8, and 9, in this embodiment, in operation, theremovable caps 17 are removed from the ends of theinlet tube 32 andoutlet tube 34, agrain vac hose 22 is connected to the external end of theoutlet tube 16 in a manner known to a person skilled in the art, theinternal orifice cover 38 is positioned in the open position as illustrated inFIG. 7 andFIG. 9 and in one embodiment, a blower orfan 24 is attached to the external end of theinlet tube 16 in a manner known to a person skilled in the art. The blower orfan 24 provides air from outside of the bin 4 through the external end of theinlet tube 16 to an area proximate theopening 36 in the concrete pad andorifice 18, and a grain vac (not shown), by means of thegrain vac hose 22, provides suction from the external end of theoutlet tube 34, the blower orfan 24 providing airflow proximate theopening 36 in the concrete pad andorifice 18 which when combined with the suction provided by the grain vac (by means of the grain vac hose 22) provides for a significant quantity of air passing theorifice 18 and thereby drawing grain through theorifice 18 into, and through theoutlet tube 34 in the direction of thegrain vac hose 22, for subsequent transfer to thegrain vac hose 22, and thereafter to the grain vac in a manner known to a person skilled in the art. In an alternative embodiment, rather than attaching a blower orfan 24 to the external end of theinlet tube 34 as previously described, after theremovable caps 17 have been removed and agrain vac hose 22 attached on one end of theoutlet tube 36, theinlet tube 16 is left open, permitting air from outside of the bin 4 to enter theinlet tube 34 by way of the slight vacuum created within the bin by the operation of the grain vac (by means of the grain vac hose 22). The embodiment of the present invention illustrated inFIGS. 6, 7 , 8, and 9 may readily be adapted for utilization in the retrofitting of grain bins which have, or previously had, installed therein grain augers beneath or within the concrete pad or floor of the bin, the retro-fit including the step of removing the auger and using the auger housing (still positioned in the concrete pad or floor) as the outlet tube, or alternatively, inserting an outlet tube of slightly smaller diameter within such housing. - As illustrated in
FIG. 9 , theinternal cover 38 is shown in the open position (positioned adjacent to the orifice 18), and as illustrated inFIG. 8 , theinternal cover 38 is shown in the closed position (theinternal cover 38 positioned directly below the orifice 18). In this embodiment, as illustrated inFIG. 5D , theinternal cover 38 is supported by and may slide along aninternal guideway 40, which may be made of, for example, channel or flat bar welded or otherwise securely fastened to the inside wall of theoutlet tube 34, it being understood that alternative guideways may be utilized to support and permit the movement of theinternal cover 20 between an open and closed position. Ahandle 28 accessible to an operator outside of thebin wall 5, fastened to the internal cover, and extending within theoutlet tube 34 through theexterior wall 5 of the bin may be utilized to move theinternal cover 38 between the open and closed position as needed, it being understood that alternative mechanisms may be utilized to move the external cover between the open and closed position. - The present invention has been described herein with regard to preferred embodiments. However, it will be obvious to persons skilled in the art that a number of variations and modifications can be made without departing from the scope of the invention as described herein.
