Abstract
A grain bin auxiliary floor that includes a plurality of generally side-by -side panels with their adjacently disposed edges overlapping one another .The panels cover an area corresponding to that of a horizontally flat circular floor of a conventional grain bin. The panels have one end thereof proximate a central portion of the flat floor and an opposite end adjacent an inner face surface of the grain bin outer wall. One end of the panels is hingedly connected to the flat floor adjacent the central portion thereof and the other end is free to move in a vertical direction. An inflatable annular air bag is located below the panels and by inflating the same the free outer ends of the panels are raised sufficiently to provide a hopper type floor that facilitates emptying grain from the bin by an auger with an in-feed end thereof located in the central portion of the floor.
Description
Title Collapsible Hopper Grain Bin Auxiliary Floor Field of Invention This invention relates generally to grain bins and more particularly to a collapsible hopper auxiliary floor for a grain bin and to a grain bin incorporating the same.
Background of Invention Storage of grain by farmers has been going on since farming began. Farmers have only a few months per year to grow and harvest their crops after which they must market their product. The farmer usually has to store at least a good portion of his crop of grain and conventionally does so in one or more grain bins on the farm.
The first storage bins were made of wood as steel was so expensive. They conventionally had an opening in the roof where the grain could be augered in from the grain truck. A small doorway at one end of the building allowed access to the inside of the building so one could shovel the grain that didn't flow by gravity from the auger outlet to the outside walls of the bin. When emptying the bin one had to shovel the grain toward the in-feed end of the auger, normally placed near the center of the bin, that didn't flow by gravity from the bin walls.
As farming became more lucrative metal type corrugated round storage bins became the standard in the industry. Mary farmers have a number of these bins which to this day are being manufactured across North America. Although round in shape they still have a flat bottom consisting generally of a flat concrete pad on which the bin is mounted. Emptying the bin still requires shoveling the grain from the walls of the bin toward the in-feed end of the auger positioned generally proximate the center of the bin floor.
The last several years has brought about another type of grain bin that is normally made of steel or corrugated galvanized metal carried by steel support beans that surround a cone shaped bottom of the bin. These bins are relatively expensive but the grain flows to the bottom exit port where the in-feed end of the auger is located eliminating the need for shoveling. This type of bin is quite a bit taller making them susceptible to wind damage and also the possibility of tipping over.

These bins are relatively expensive but the grain flows to the bottom exit port where the in-feed end of the auger is located eliminating the need for shoveling. This type of bin is quite a bit taller making them susceptible to wind damage and also the possibility of tipping over.
With specialty crops such as lentils, peas, canola, etc a hopper type bin bottom is needed more than ever simply because these grains do not flow as readily as wheat, flax and other standard crops thus requiring more shoveling.Bins with hopper type bottoms also save the farmer from having to breath grain dust that otherwise occurs during shoveling..
Although these bins with hopper bottoms are very expensive farmers are purchasing the same to save them time and generally make farming easier.
There are numerous flat bottom bins in use that could serve for many years to come if they could be provided with a hopper type bottom. A hopper type bin add on bottom was attempted several years ago. It consisted of building a hopper bottom inside the bin but this eliminated one third of the bins capacity thereby making it impractical. Since the majority of the bins on the farms today are still of the flat bottom type what is needed is a method of converting them to a cost effecting hopper type bin bottom and particularly without any material loss of its original capacity.
Summary of Invention A principal object of the present invention is to provide means for changing the flat bottom state of a bin to a hopper state bottom for expelling the bins contents reducing or eliminating the need for shoveling and furthermore have the bin retain essentially it's original volume for grain storage.
According to the present invention there is provided a false or auxiliary bin floor or bottom that covers the entire storage bin floor and consists of a plurality of pie shaped overlapping panel that are anchored at the narrow end thereof to a ring secured to the bin floor proximate the center thereof and at the opposite end are free to move up and down.
Below the panels there is means spaced a selected distance from the center of the bin floor to cause the free outer ends of the panel to be raised and thereby provide a hopper type bottom to facilitate emptying the grain from the bin. The panel raising means comprises an annular inflatable tube located between the hopper flat bottom and the segmental floor panels and is spaced a selected distance from the center of the bin. A metal plate is secured to the bin floor and connected thereto is a metal ring. The pie shaped panel are hingedly connected to the metal ring at their narrower inner end and the larger outer end is free to move in proximity of the inner surface of the bin outer wall. Inflating the air tube causes the outer ends of the panels to rise and together they gradually create a hopper type floor where the panels may slope for example 40 - 45 degrees. This temporary hopper type floor causes the grain in the bin to flow by gravity to a discharge opening at the center of the bin floor or in the bin where the infeed end of an auger is located that delivers the grain to a waiting truck.
Attached to the free outer end of each panel is a flap that is resiliently biased against the inner surface of the bin outer wall. Along a bottom circumferential portion of the grain bin sheets of for example a plastics material are placed and attached to provide a smooth surface covering the corrugated surface and bolts used to assemble the bin outer wall. This allows the resiliently biased flaps on the ends of the pie shaped panels to keep a smooth tight fit thereby preventing grain kernels from falling behind the false floor instead of flowing to the center of the bin floor to be augured out.
When the bin has been emptied of it's grain air is allowed to escape, for example by opening a valve, allowing the floor to recede back to it's initial flat position. Should the auxiliary floor not return completely to it's flat state ( due to friction between adjacent edges of the panels 1 S and/or against the outer walls) the weight of grain, when the bin is next being filled with grain will force the air out of the air bag and return the auxiliary floor to it's normal flat position.
In keeping with the forgoing there is particularly provided in accordance with one aspect of the present invention a grain bin auxiliary floor comprising a plurality of side-by -side panels having adjacently disposed longitudinal edges overlapping one another, said panels covering a selected area corresponding to that of a horizontally flat floor of a selected conventional grain bin, said panels having one end thereof proximate the center of said flat floor and an opposite end adjacent an inner face surface of the grain bin outer wall, means hingedly attaching said one end of said panels to said flat floor, means for selectively raising said opposite ends of said panels and thereby provide a hopper type floor that facilitates emptying grain from said bin by an auger with an in-feed end thereof located proximate the center of said flat floor and means preventing grain from escaping to a position below said auxiliary floor.
Brief Description of the Drawings The invention is illustrated, by way of example, with reference to the accompanying drawings wherein:
Figure 1 is a diagrammatic vertical sectional view of a standard metal storage bin mounted on a conventional flat floor and including, in keeping with the present invention, means proximate the center of the bin to anchor thereto a mufti-section auxiliary floor provided by the present invention;
Figure 2 is a top plan view of the flat bin floor and including an annular air inflatable bladder resting thereon and which provides means to raise the free outer end of floor panels of the auxiliary floor;
Figure 3 is a top plan view of applicants mufti-panel auxiliary bin floor that overlies the air inflatable bladder shown in figure 2;
Figure 4 is a diagrammatic vertical sectional view of a grain storage bin with applicants auxiliary mufti-segment floor mounted on the floor thereof and in it's normal flat state; and Figure 5 is similar to figure 4 but illustrating the auxiliary floor in it's hopper state caused by inflation of the air bag.
Detailed description of the Preferred Embodiment Referring to the drawings there is illustrated a circular grain storage bin having a flat concrete floor 10 with a metal plate 11 secured thereto and to which there is attached a metal ring 12. An auxiliary floor is made from a plurality of pie shaped panels 19 that are hingedly attached at the narrow inner ends thereof as indicated at 20 to the annular ring. An annular air bag 13 capable of being inflated or deflated by adding or removing air rests on the concrete floor and is located under the panels l9.The annular air bag 13 is space a selected distance from the center of the floor and as it increases in size during inflation the outer ends of the panels are caused to move upward providing a surface that slopes toward the center of the bin. There is thereby provided an auxiliary floor that in one state is flat and in the other state becomes a hopper type floor. In the hopper state the grain 26 in the bin is caused to flow by gravity to the center of the bin where the inlet end of an auger is located when emptying the bin.The auger is used to move the grain from the bin into a truck located outside of the bin.
The pie shaped panels have a free outer end disposed adjacent the inner wall of the bin.
A flap or panel 22 is attached to this free outer end of each of the panelsl9 . The flaps are resiliently biased so as to remain in contact with the inner surface of the bin wall as the end of the panels are raised thereby preventing kernals of grain from getting below the auxiliary floor.. Panels 17 are fastened to the lower inner portion of the bin outer wall and provide a smooth inner face covering the corrugated surface panels providing the bins side wall 18 and 5 bolts used to assemble the wall.
A compressor outside of the bin proximate bin entry door 25 supplies air via hose means 14 to the air bag 13..
To allow the free outer ends of the panels 19 to move up and down in the circular bin the long edges of adjacent panels overlap one another. Each panell9 has a stiffener beam 23b except for the panel 19 proximate the bin entry door 25 which has two stiffener beams 23a.
These stiffening beams( or ribs) helps reduce the stress on the panels as the air bag is inflated.
The panel with the two stiffening beams is also made of heavier material than the remaining panels because of the auger weight. The two beams( located on the upper surface) also provide a guide for the auger in-feed end to reach the center of the bin floor where the floor plate 11 is located.
A section of the air bag 13 that faces the doorway 25 has webbing wrapped tightly there around to decrease its diameter less than the rest of the tubing, This prevents raising the panel 19, below the auger tube, above a selected height above which the infeed end of the auger would be raised offthe floor .Both sides of the panels facing the doorway 25 have adjacent panel edges interconnected by means 24 consisting of a flexible material This flexible material spans the gap between adjacent panels that occurs when the panel under the auger tubing has reached it's predetermined height and the remaining panels continue rising as the air bag is further inflated. This prevents grain from escaping to space between the bin floor and the auxiliary floor.
The air bag 13 is also loosely wrapped by suitable means 16 that protects the tubing from abrasion and also prevents the air bag from over expanding from pressurization. The air bag 13 is held in position on the cement floor by three webbing straps 15 that are anchored to the floor plate 11 Figure 4 illustrates the grain 26 having been lowered in the bin to the point where the grain will no longer flow by gravity to the inlet end of an auger used to empty the bin. The hopper auxiliary floor bottom is in a horizontal flat state with the air bag 13 deflated. The bin thus is able to hold it's original capacity of stored grain 26.
Figure 5 illustrates the auxiliary floor in it's hopper state where the free outer ends of the panels have been raised by inflation of the air bag. The panels slope sufficiently as to cause the grain in the bin to flow by gravity to the in-feed end of the auger.
In figure 3 the panels 19 are perforated throughout their surface by holes 21 so that air can be caused to flow there through for drying the grain. The perforations allow the flow of air from beneath the false floor through the grain to help remove excess moisture and heat from the stored grain.
Although these bins with hopper bottoms are very expensive farmers are purchasing the same to save them time and generally make farming easier.
