US 5,393,139 A · Mixing blade mounting assembly

Abstract

A mounting assembly for the primary mixing paddles in a pan-type mixer includes a single bolt paddle support arm mounting and adjustment device, and a two bolt paddle mounting feature, both of which are constructed and located to provide reliable adjustability and demountability and to protect the assemblies against the ingress of contaminants and abrasive wear from the materials being mixed. The single bolt clamping device also provides simple vertical adjustment of the paddle height in a manner which retains the adjustment mechanism enclosed against the entry of contaminants. The two bolt paddle mounting assembly encloses both threaded connections inside the body of the paddles, and includes a protective enclosing shroud and positions the exposed bolt heads at the back of the assembly out of the direct path of abrasive materials.
