Abstract

A mobile concrete mixing apparatus comprising an aggregate storage bin and cement storage bin mounted on a mobile carrier in spaced relation, a water supply tank mounted on the carrier and in operable communication with a water discharge pipe disposed in the proximity of the cement storage bin, a conveyor apparatus movable beneath and between the aggregate storage bin and cement storage bin for moving materials therefrom for discharge into a mixing auger assembly, the aggregate storage bin containing premixed sand and rock materials for achieving a homogeneous moisture and temperature therebetween, the sand-rock mixture, cement mixture and water being mixed together prior to admission thereof into the mixing auger assembly, the auger assembly comprising a plurality of material moving stages and a plurality of mixing stages interposed therebetween to assure a homogeneous mixture for delivery from the mixing auger assembly, all of the operation of the concrete mixing apparatus being initiated by a single lever operation.

Claims

1. A truck having a forward and rearward end and having means for delivery of material comprising:

a vertical material discharge chute adjacent the truck lower rearward and;

an annular gear surrounding said discharge chute rotating about a vertical axis;

opposed flanges connected to and extending downwardly from said chute and rotated in a horizontal plane by said annular gear;

an elongated auger having an inlet opening adjacent the first end and an outlet opening adjacent the second end, the first end of the auger being pivotally secured to said flanges whereby the auger is supported at the first end and is pivotal in a vertical plane;

a cable having one end affixed to said auger adjacent said second end, the other end of the cable being secured to the truck whereby the auger is supported at both ends;

a power driven gear supported to said truck adjacent said chute, the power driven gear rotating about its vertical axis; and

a chain received around said annular gear and said power driven gear whereby said auger is pivotal in a horizontal plane to properly position said outlet opening for delivery of material.
