Abstract:
An improved and cost effective stored grain cooling system that comprises at least one device that draws air attached to an outside area of a bin and also comprises a perforated pipe that faces in the direction of the device that draws air. 
     The perforated pipe leads to an outlet that eventually leads to the device that draws air, which allows for heat produced by stored grain to effectively cool. The perforated pipe is suspended in the bin and tightly fits into the outlet leading to the device that draws air. The pipe is suspended by a system of rope-like and chain-like elements that are attached to the pipe and extend outwards and attach to respective areas of the bin.

Description:
BACKGROUND 
       [0001]    Grain storing and cooling bins have been around for many years. Usually, grain bins are made up of a concrete base, a sidewall forming a cylindrical housing, and a roof. In the housing or the roof of the grain bin there are often outlets that allow for hot air to escape from the grain bin. Usually mounted over the outlets or mounted within proximity to the outlets is a ventilation system, fan, or turbine. These common devices for circulating air are a common part of grain bins and are useful in assisting the cooling and drying of grain stored in a bin. 
         [0002]    Historically, devices that circulate air were positioned on the outside of the sidewall of the bin. While such a mounting is satisfactory, it often leads to uneven airflow. Several modern embodiments of storing and cooling bins, mount the air circulating devices on the roof of the bin. Mounting a air circulating device on the roof takes advantage of the physical nature of hot air traveling upwards. 
         [0003]    In embodiments of grain bins, such as the embodiment disclosed in U.S. Pat. No. 4,305,490, the air circulating device is positioned on the roof of the grain bin and the circulation of air is assisted by the device and a complex system of air vents as described in the patent. 
         [0004]    Needed in the industry of grain storage, is a stored grain cooling system that makes use of a simpler system for keeping stored grain cool and dry. 
       SUMMARY 
       [0005]    A stored grain cooling system that comprises a device that draws air out of a grain storage bin. The system comprises perforated pipe that leads to an outlet of a bin. The perforated pipe draws warm air out of grain stored in a bin, which allows for hot air to escape the bin and the grain to effectively cool. 
         [0006]    In addition, the perforated pipe is suspended in the bin and a telescoping part of the pipe tightly fits into an outlet of a bin, which leads to a device that draws air. The perforated pipe is suspended by a system of chain-like elements that are attached to the pipe and extend outwards and attach to respective areas of a bin.

     DETAILED DESCRIPTION 
       [0011]    The present specification explains preferred embodiments of a stored grain cooling system. The present detailed description does not limit the system and the system may embody various forms. Furthermore, FIGS. one through four illustrate a preferred embodiment of the system and the figures are merely devices for assisting the explanation of the present detailed description and do not limit the scope of the system. 
         [0012]    As illustrated by FIGS. one and two, in general, a bin that employs the stored grain cooling system comprises at least one sidewall  1 ; a top  2 ; at least one outlet  3 . The stored grain cooling system comprises at least one device that draws air  4  that attaches to an outside area of a bin and covers the outlet  3  of a bin. Furthermore the system comprises at least one perforated pipe  5   b,  comprising a front-end  6  and a back-end  7 , which suspends in a bin, and a upper telescoping part  5   a  that tightly fits into the outlet  3  of a bin and is removable from the outlet  3 . 
         [0013]    In preferred embodiments of the stored grain cooling system, the device that draws air  4  is a turbine (see FIG. two). 
         [0014]    In preferred embodiments of the stored grain cooling system, the device that draws air comprises: at least one small hole; an outside area that comprises at least one small hole; and a pin that inserts into the hole, which secures the device that draws air to an outside area of a grain storage bin. 
         [0015]    In preferred embodiments of the stored grain cooling system, the telescoping part comprises a handle. It is also preferred that the handle attaches to the telescoping part on the front-end of the part. This allows the telescoping part to be pulled out of grain once the bin has been filled with grain. 
         [0016]    As shown in FIGS. three and four, in other preferred embodiments of the stored grain cooling system, the telescoping part  5   a  comprises a removable cap  8 ; and the cap  8  comprises a handle  9 . By capping the telescoping part  5   a,  grain does not fill the perforated pipe  5   b.  Furthermore, having the handle  9  on the top or on the front-end of the part  5   a,  the perforated pipe  5   b  becomes easier to grab out of grain stored in a bin. 
         [0017]    In preferred embodiments of the stored grain cooling system, the cap  8  may be attached to the telescoping part  5   a  by a pin  10  and at least one hole  11   a  on the cap  8  and at least one hole  11   b  on the telescoping part  5   a.  In other words, the cap  8  and front-end of the telescoping part  5   a  may each comprise at least one small hole  11   a  &amp;  11   b  and a pin that inserts into the small holes  11   a  &amp;  11   b,  which secures the cap  8  to the telescoping part  5   a.  In other embodiments of the system, the cap secures to the perforated pipe in various manners known to those skilled in the art.

In this embodiment, the three chain-like elements  12   a,    12   b,  &amp;  12   c  also respectively attach to three separate points  14   a,    14   b,  &amp;  14   c  on an upper-area of a bin that are approximately equal distance from each other. In addition, the three chain-like elements  12   a,    12   b,  &amp;  12   c  have approximately equal lengths when measuring the length of each chain-like element  12   a,    12   b,  or  12   c  from its two points of attachment. 
         [0022]    Moreover, in preferred embodiments of the stored grain cooling system where a top area of a bin comprises an outlet, the pipe suspension system also comprises at least one rope-like element that comprises a first-end that attaches to the back-end of the perforated pipe and a second-end that attaches to an inside surface of a sidewall of a bin.
