AN IMPROVED SAFETY ARRANGEMENT FOR GRAIN AUGERS AND THE LIKE

摘要

This invention provides an improved, safety overload prevention device for a material conveying auger which includes an auger casing, a main drive shaft journalled therein and a main auger flight secured around the shaft, an intake flight section (11) secured to and extending along a tubular support sleeve (12) rotatably mounted on an intake drive shaft portion (14) which is adapted for connection to the main drive shaft of the auger so as to rotate therewith, and a clutch device (18) operatively interconnecting the tubular sleeve (12) and the drive shaft portion (14), the clutch device (18) including a radially displaceable spring loaded detent (19) movable between an engaged position wherein the tubular sleeve (12) is fast with the drive shaft portion (14) and rotates therewith, and a disengaged position wherein drive to the tubular sleeve (12) is disengaged in the event of an obstruction, such as a leg or arm being trapped in the flighting.
