Abstract
A motor driven discharge chute control system for automatically controlling the lateral position of a concrete discharge chute associated with a transit mixer vehicle is disclosed including a reversing motor connected to an output gear normally engaged to rotate with the motor through a gear reducer. A rotating chute swing gear is driven by the output gear and rotates a connected pivot assembly that carries one end of a discharge chute. A manual override system is also provided.
Claims15
A motor driven discharge chute control system for controlling the lateral position of a concrete discharge chute associated with a transit mixer vehicle comprising:
- (a) a motor for reversibly rotating a motor shaft;
- (b) an output gear mounted and to rotate with an output drive shaft normally engaged to rotate with said motor shaft;
- (c) a chute swing gear member mounted to enmesh with and be angularly displaced in response to the rotation of said output gear;
- and
- (d) a pivot assembly for carrying one end of a discharge chute directly contacting said chute swing gear member in a manner such that angular displacement of said swing gear member directly pivots said pivot assembly, wherein said pivot assembly is nested in an opening in said swing gear member.
A concrete transit mixer truck comprising:
- (a) a chassis;
- (b) a driven concrete mixing drum mounted to rotate on said chassis and having a charge and discharge opening therein;
- (c) a system for dispensing concrete from said drum mounted on said chassis including a discharge chute juxtaposed and receiving concrete from said discharge opening;
- and
- (d) a motor driven discharge chute control system for controlling the lateral disposition of said discharge chute, said system further comprising:
- (1) a motor for reversibly rotating a motor shaft;
- (2) an output gear mounted and to rotate with an output drive shaft normally engaged to rotate with said motor shaft;
- (3) a chute swing gear member mounted to enmesh with and be angularly displaced in response to the rotation of said output gear;
- and
- (4) a pivot assembly for carrying one end of a discharge chute directly contacting said chute swing gear member in a manner such that angular displacement of said swing gear member directly pivots said pivot assembly, wherein said pivot assembly is nested in an opening in said swing gear member.
