Abstract
Abstract A modular plow system for mixers and the like of the type employing a mixing chamber for holding a quantity of material wherein the chamber includes a bottom wall and a peripheral sidewall and a rotary mixing head mounted therein. The mixing head includes plow support means movable over the bottom wall, and a plow backing member is provided with an advancing face angularly disposed with respect to the bottom wall of the chamber and a lower edge spaced above the bottom wall. A planar, modular, replaceable plow member is removably mounted on the advancing face of the backing member and means are provided for securing the plow member to the backing member in a plurality of different positions whereby a selected edge of the plow may be placed in the region of most intense wear.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
173 words
A modular plow system for mixers of different sizes which include mixing chambers of different dimensions for holding a quantity of material to be conditioned, said chambers including a bottom wall, a peripheral sidewall and a rotary mixing head mounted in said chamber including plow support means having a support plate parallel to and movable over said bottom wall; said plow system comprising a plow backing member detachably mounted on said plow support plate and including a downwardly depending advancing face angularly disposed with respect to said bottom wall and a lower edge spaced above said bottom wall; at least one rectangular shaped, planar, modular plow of standard size removably mounted on said advancing face of said backing member, saId plow having at least one pair of abrasion-resistant edge portions on an outer face along substantially parallel opposite edges thereof; and means for securing said plow to said backing member in first and second positions, respectively, wherein a selected one of said opposite edges is adjacent said lower edge of said backing member.
Claim 2
Dependent Claim
173 words
A modular plow system for mixers of different sizes which include mixing chambers of different dimensions for holding a quantity of material to be conditioned, said chambers including a bottom wall, a peripheral sidewall and a rotary mixing head mounted in said chamber including plow support means having a support plate parallel to and movable over said bottom wall; said plow system comprising a plow backing member detachably mounted on said plow support plate and including a downwardly depending advancing face angularly disposed with respect to said bottom wall and a lower edge spaced above said bottom wall; at least one rectangular shaped, planar, modular plow of standard size removably mounted on said advancing face of said backing member, saId plow having at least one pair of abrasion-resistant edge portions on an outer face along substantially parallel opposite edges thereof; and means for securing said plow to said backing member in first and second positions, respectively, wherein a selected one of said opposite edges is adjacent said lower edge of said backing member.
Claim 3
Dependent Claim
39 words
The modular plow system of claim 1 including a plurality of said modular plows of equal size mounted in a horizontal row on said advancing face of backing member and interchangeable from one position in the row to another.
Claim 4
Dependent Claim
36 words
The modular plow system of claim 1 including a plurality of said modular plows of equal size mounted in vertically stacked rows on said advancing face of backing member and interchangeable from one row to another.
Claim 5
Dependent Claim
69 words
The modular plow system of claim 1 wherein said system comprises a pair of said plow backing members supported from said mixing head and spaced at different distances outwardly of the center of said bottom wall of said chamber comprising inner and outer members; a plurality of said modular plows of equal size mounted on said inner and outer plow backing members and interchangeable from one to the other.
Claim 6
Dependent Claim
59 words
The modular plow system of claim 1 wherein said advancing face of said backing member is sloped at an acute angle to the bottom wall of said mixing chamber, said modular plow having chamfered corners along said opposite edges to provide a desired clearance distance between the lower edge of said outer face and said mixing chamber bottom wall.
Claim 7
Dependent Claim
55 words
The modular plow system of claim 1 wherein said last-mentioned means comprises a plurality of removable fasteners and slot means defined in said backing members, said fasteners adjustable vertically in said slot means permitting a lower edge of said modular plow to be adjusted a selected clearance distance above said bottom wall of said chamber.
Claim 8
Dependent Claim
68 words
A mixer for abrasive materials and the like comprising a modular plow system as defined in claim 1, said mixing head including plow support means carrying an inner one of said backing members adjacent the axis of rotation of said mixing head and an outer backing member spaced outwardly of said axis, a plurality of said modular plows interchangeably mounted on said advancing faces of said backing members.
Claim 9
Dependent Claim
26 words
The mixer of claim 7 including a plurality of said modular plows mounted in end-to-end relation on the advancing face of one of said backing members.
