I came across an article which describes DIY system for unclogging grain bin augers from outside of the bin. This is a big deal in terms of improving safety, since entering a grain bin to remove clogs is one of the most dangerous tasks on the farm. With the wet weather this year and the late harvest, wet grain and clogs have been a huge problem this year. It seems like hardly a week has gone by lately where I haven’t seen an article about someone becoming trapped in a grain bin, and way too often these incidents have been fatal.
The DIY solution for clearing a clog from the outside was designed by Guy Mills, a Nebraska farmer. His solution uses a hose, a steel pipe, two elbow joints, and a heavy duty (250cfm) compressor to blow the clogs out/apart a few inches at a time. While most compressors that you would use to say put air in tires or operate drills don’t have that kind of pressure, most rental places have them for less than $50 a day. The compressor really packs a punch though, so if your bin is older use caution so that you don’t accidentally cause damage in the process of removing clogs. Also since this solution uses compressed air at very high pressures/velocities be extremely careful that the components you choose and your assembly methods are able to handle the pressure and follow all safety recommendations for the compressor itself.
Here is the link to the original article which gives more detailed instructions on how to build and use the de-clogger:
