Abstract
A hopper support cone for a grain bin includes a perimeter footing support, upstanding support legs mounted on the footing support, and an inverted cone shaped hopper wall carried by the support legs in a suspended position above a support surface. The hopper support cone features top and bottom junctions respectively located at top and bottom ends of support legs and respectively joining each support leg to each of the hopper wall and the footing support. Each of the top and bottom junctions comprise upper and lower bracing members forming gusset- like structures which provide rigidity for the hopper support cone while leaving a continuous portion of the length of each support leg uninterrupted between the top and bottom junctions and a continuous portion of the hopper wall uninterrupted from the central opening thereof towards the peripheral edge. Thus, access to the continuous portion of the hopper wall is unobstructed.
Description
GRAIN BIN HOPPER SUPPORT CONE WITH SUPPORT LEGS WHICH
ARE UNINTERRUPTED ALONG THEIR RESPECTIVE LENGTHS
BETWEEN TOP AND BOTTOM JUNCTIONS
FIELD OF THE INVENTION
The present invention relates generally to grain bins and more particularly to structural bracing features of hopper support cones for grain bins.
BACKGROUND
Traditionally, a frame system of a hopper bottom or support cone comprises radial frame members spanning radially inwardly from support legs of the hopper bottom to an inverted cone shaped hopper wall at a location near a bottom end thereof which locates a central opening. These radial frame members are considered to be essential components of conventional and commercially available hopper bottoms so as to provide sufficient support to the grain bin supported above the hopper cone; however, the radial frame members found in conventional hopper support cones obstruct access circumferentially around the hopper wall from the central opening upwardly along a height of the hopper wall. The obstruction of the radial frame members can make it difficult to manipulate the position of a transfer conveyor inlet such as an auger inlet below the central opening for transferring particulate material stored in the grain bin to another location.
Canadian Patent Application No. 2,825,610 belonging to the current applicant schematically illustrates a hopper bottom or support cone having support legs connected at a bottom end by a perimeter footing. Although the support legs are shown to be uninterrupted along their length between a top junction with the cone and a bottom junction with the perimeter footing, in practice radial frame members are

DETAILED DESCRIPTION
Referring to the accompanying figures, there is illustrated a hopper support cone generally indicated by reference numeral 10 for supporting a grain bin thereon. The hopper support cone is suited for center unloading of the grain bin. Such hopper support cones may be formed integrally with the grain bin or may be formed as a separate component upon which a commercially available cylindrical bin wall is then supported, as in the first illustrated embodiment in which the cylindrical bin wall is indicated at 2.
The hopper support cone 10 comprises a hopper wall 12 which takes the shape of an inverted cone. Thus, the hopper wall extends at a downward and inward incline in a tapering fashion from a circumferentially extending peripheral edge 14 at a top end to a central opening 16 at a bottom end. A suitable gate member 17 is
8 mounted across the central opening for selectively enclosing the opening. The peripheral edge 14 and the central opening 16 are coaxially aligned with respect to a vertically oriented longitudinal axis of the hopper wall and thus are longitudinally spaced from one another. Moreover, the peripheral edge 14 corresponds approximately in diameter to the diameter of the cylindrical bin wall 2 such that the cylindrical bin wall is arranged to be supported directly on or above the top peripheral edge of the hopper wall 12.
The hopper support cone includes a plurality of support legs 18 for supporting the hopper wall in a position spaced above a support surface. The support legs 18 are located at equally circumferentially spaced positions about the hopper wall 12. Each support leg carries the hopper wall with a top end 18A of the respective support leg located near the top end of the hopper wall 12 so as to be closer to the peripheral edge 14 than to the central opening 16. The respective leg 18 spans vertically downwardly, parallel to the longitudinal axis of the hopper wall 12, from the top end 18A of the respective support leg that is at the peripheral edge of the hopper wall to a bottom end 18B of the support leg which is downwardly below the central opening 16 such that the central opening is held spaced above the support surface. In the illustrated embodiment, the support legs 18 are tubular and are rectangular, for example square, in cross-section transverse to their length. Furthermore, the illustrated embodiment of Figures 1-3 shows six support legs; however, in other embodiments, a number of the support legs may be different than that shown in accordance with the first illustrated embodiment.
The hopper support cone 10 includes an annular perimeter footing support 20 mounted at the bottom ends 18B of the support legs. The footing support 20 spans between each adjacent pair of the legs 18 so as join all of the legs for
The hopper support cone includes a plurality of support legs 18 for supporting the hopper wall in a position spaced above a support surface. The support legs 18 are located at equally circumferentially spaced positions about the hopper wall 12. Each support leg carries the hopper wall with a top end 18A of the respective support leg located near the top end of the hopper wall 12 so as to be closer to the peripheral edge 14 than to the central opening 16. The respective leg 18 spans vertically downwardly, parallel to the longitudinal axis of the hopper wall 12, from the top end 18A of the respective support leg that is at the peripheral edge of the hopper wall to a bottom end 18B of the support leg which is downwardly below the central opening 16 such that the central opening is held spaced above the support surface. In the illustrated embodiment, the support legs 18 are tubular and are rectangular, for example square, in cross-section transverse to their length. Furthermore, the illustrated embodiment of Figures 1-3 shows six support legs; however, in other embodiments, a number of the support legs may be different than that shown in accordance with the first illustrated embodiment.
The hopper support cone 10 includes an annular perimeter footing support 20 mounted at the bottom ends 18B of the support legs. The footing support 20 spans between each adjacent pair of the legs 18 so as join all of the legs for
9 resting on the support surface. As such, the footing support is arranged to be supported on the support surface such as the ground or a suitable foundation so as to lie in a generally horizontal plane with a diameter which corresponds approximately to the diameter of the cylindrical bin wall 2 to be supported thereon. In the illustrated embodiment, the footing support 20 is an endless tubular member which is circular in shape (in plan view). However, in other embodiments, the annular perimeter footing support may be in the form of a polygon with a number of sides or segment equal to the number of the support legs 18. For example, as in Figure 4 and indicated at 20', the annular perimeter footing support may be octagonal in shape so as to locate each one of the eight support legs of a second illustrated embodiment at a respective vertex of the octagon shaped footing support. Further to the diameter of the footing support, a width of the tubular member is greater than a thickness of the support leg measured across the width of the tubular member which forms the footing support.
The support legs 18 are positioned on the footing support 20 such that outer faces 19A of the support legs that face outwardly away from the hopper wall are generally aligned in a vertical plane with a peripheral outer face 20A of the footing support about an outer periphery thereof. Since the footing support's tubular member is wider in a transverse direction than a thickness of the respective support leg 18, a peripheral inner face 20B of the footing support about an inner periphery thereof is spaced radially inwardly from inner faces 19B of the support legs that face inwardly towards the hopper wall. The inner face 20B of the footing support is also spaced radially outwardly from the central opening 16 such that the central opening is locatable directly over the support surface.
Further to the support legs 18, the hopper support cone 10 includes top and bottom junctions 30 and 40 respectively located at top and bottom ends 18A
and 18B of the support legs. The top junctions 30 join each support leg 18 and the hopper wall 12, and the bottom junctions 40 join each support leg 18 and the footing support 20. As such, the top and bottom junctions are suited for bracing or strengthening connection of the legs 18 to each of the hopper wall 12 and the footing support 20 5 thereby rigidifying the hopper support cone.
More specifically, each top junction 30 comprises an upper bracing member 32 such as a gusset plate which is mounted centrally relative to the inner face 19B of the support leg so as to be centered relative to a width of the support leg 18 that is taken or measured along the circumference of the footing support 20. The
The support legs 18 are positioned on the footing support 20 such that outer faces 19A of the support legs that face outwardly away from the hopper wall are generally aligned in a vertical plane with a peripheral outer face 20A of the footing support about an outer periphery thereof. Since the footing support's tubular member is wider in a transverse direction than a thickness of the respective support leg 18, a peripheral inner face 20B of the footing support about an inner periphery thereof is spaced radially inwardly from inner faces 19B of the support legs that face inwardly towards the hopper wall. The inner face 20B of the footing support is also spaced radially outwardly from the central opening 16 such that the central opening is locatable directly over the support surface.
Further to the support legs 18, the hopper support cone 10 includes top and bottom junctions 30 and 40 respectively located at top and bottom ends 18A
and 18B of the support legs. The top junctions 30 join each support leg 18 and the hopper wall 12, and the bottom junctions 40 join each support leg 18 and the footing support 20. As such, the top and bottom junctions are suited for bracing or strengthening connection of the legs 18 to each of the hopper wall 12 and the footing support 20 5 thereby rigidifying the hopper support cone.
More specifically, each top junction 30 comprises an upper bracing member 32 such as a gusset plate which is mounted centrally relative to the inner face 19B of the support leg so as to be centered relative to a width of the support leg 18 that is taken or measured along the circumference of the footing support 20. The
10 upper bracing member 32 spans radially between the respective support leg 18 at an upper bracing location thereon, indicated at `UB', and the hopper wall 12 at a wall location thereon which is indicated at 'W'. The upper bracing location UB on each leg is closer to the top end 18A than to the bottom end 18B of the respective support leg.
Similarly, the wall location W is closer to the peripheral edge 14 than to the central opening 16 of the hopper wall. In the illustrated embodiment which employs gusset plates 32 disposed at the top ends 18A of the support legs as the upper bracing members, a free edge 32A of the respective gusset plate spans between the upper bracing location UB and the wall location W. Also, a leg edge 32B of each gusset plate 32 extends along an upper portion of the length of the respective leg 18 between the top end 18A thereof and the upper bracing location UB thereon.
Furthermore, a wall edge 32C of the respective gusset plate extends along the hopper wall 12 from the top end 18A of the respective support leg to the wall location W on the hopper wall. Thus, the upper bracing members 32 provide rigidity in directions along the longitudinal axis of the hopper wall 12 and in transverse directions with respect to the hopper wall's longitudinal axis.
Similarly, the wall location W is closer to the peripheral edge 14 than to the central opening 16 of the hopper wall. In the illustrated embodiment which employs gusset plates 32 disposed at the top ends 18A of the support legs as the upper bracing members, a free edge 32A of the respective gusset plate spans between the upper bracing location UB and the wall location W. Also, a leg edge 32B of each gusset plate 32 extends along an upper portion of the length of the respective leg 18 between the top end 18A thereof and the upper bracing location UB thereon.
