Floating mixing chamber for reclaiming machines

Abstract

A support assembly for supporting a mixing chamber of a reclaiming machine having a frame includes a rod member pivotally mounted on the frame at end portions, a stop member, and a L-linkage attached to the rod member. The L-linkage is further attached to the mixing chamber. The stop member is configured to rotate with the movement of the mixing chamber. Further, a float linkage is provided. The float linkage is capable of being abutted with the stop members and pivotally attached to the rod member. The float linkage is configured to stop the rotation of stop member. Further, a hydraulic cylinder is provided. The hydraulic cylinder connected with the float linkage and the frame. The hydraulic cylinder is configured to adjust the float linkage to one of a plurality of positions.

What is claimed is: 
     
         1 . A support assembly for floating a mixing chamber of an earth working machine having a frame and a mixing chamber, the support assembly comprising:
 a rod member comprising a first end portion and a second end portion, wherein the rod member is pivotally coupled to the frame at the first end portion and the second end portion;   an L-linkage comprising a first end and a second end, the first end coupled to the rod member and the second end coupled to the mixing chamber, wherein the L-linkage is configured to translate an upward and downward movement of the mixing chamber into rotation of the rod member;   a stop member coupled to one of the first end portion and the second end portion of the rod member and configured to rotate with the rotation of the rod member;   a float linkage comprising a base plate, a first section, a second section, and a spring mounted on the base plate, wherein the first section is pivotally coupled to one of the first end portion and the second end portion of the rod member, and wherein the spring is capable of being abutted with the stop member; and   a hydraulic cylinder attached to the second section of the float linkage, wherein the hydraulic cylinder is configured to extend and retract to cause pivoting movement of the float linkage at the first section and adjust a position of the float linkage to one of a plurality of positions.
