ABSTRACT:
A gathering platform extends forwardly from the front end of a mixing machine and has an upper surface in which a pair of counter-rotating gathering discs are rotatably mounted. Each disc is rotated to move mined material centrally and rearwardly on the platform upper surface toward a material guide that extends rearwardly in overlying relation with a portion of each of the gathering discs to the receiving end of a longitudinally extending conveyor. A plurality of radially extending slots extend through each disc, and a material gathering arm is positioned in each slot. One end of each arm is connected to rotate with the gathering disc. The opposite end of the arm rides on a cam surface in the gathering platform. The cam surface has a first portion and a second portion. The second portion is positioned at an elevation below the first portion and beneath the material guide. Upon each revolution of the gathering discs the arms follow the cam surface to move upwardly and downwardly in the slots to extend above the upper surface of the material guide to sweep the discs and to drop below the lower surface of the material guide to pass beneath the material guide.
