Knocker Stops Bridging In Feed Bin
Anyone who feeds livestock or poultry out of a bulk feed bin has probably had plenty of experience with bridged feed. It's not unusual to see a rubber mallet hanging from a string on many bulk bins to be used to solve the problem whenever it arises.
R.E. Charlton, Jr., Dillwyn, Va., decided to solve the problem permanently with an automatic "bin knocker" that automatically strikes the bottom of the bin two times a minute.
A pulley on the end of the bin unloading auger belt-drives a small 150:1 gearbox (salvaged from an aircraft engine starter).
The gearbox drives an old silage wagon unloading drive with a large crank welded onto the shaft. As the crank comes around it engages a lever which releases a spring-loaded rubber hammer that strikes the bottom of the bin. As the erank comes around, it resets the hammer.
Charlton says that once he got it set up, his "bin knocker" works unattended whenever the auger runs. "It totally eliminated feed bridging problems," he says.
