Abstract
A self-leveling crop spraying apparatus is carried by a prime mover, The crop spraying apparatus includes first and second masts, and first and second opposed pendulum arm frame members slidingly engaged to the fast and second masts. A pendulum arm extends through the first and second opposed pendulum arm frame members. The first and second pendulum assemblies are coupled to opposed ends of the pendulum arm, and a carriage assembly is carried by the first and second pendulum assemblies. The carriage assembly is rotatable relative to the first and second masts and first and second opposed pendulum arm frame members.
Claims5
A self-leveling apparatus, comprising:
- a carriage assembly comprising an elongate carriage frame having a first lengthened carriage frame member and a second lengthened carriage frame member spaced apart by a first carriage frame spacer and a second carriage frame spacer, wherein the first and second carriage frame spacers are spaced apart from each other and extend between the first lengthened carriage frame member and the second lengthened carriage frame member, and wherein the first and second carriage frame spacers permit rotational movement of the first and second lengthened carriage frame members about the longitudinal axis;
- a carriage assembly support frame coupled between the carriage assembly and a vehicle, wherein the carriage assembly support frame comprises opposed forward and rearward pendulum arm frame members, wherein the carriage assembly is longitudinally moveable along the carriage assembly support frame between a raised position and a lowered position;
- a left boom and a right boom coupled to the elongate carriage frame of the carriage assembly;
- a first pendulum assembly having a first pivot coupled to the carriage assembly;
- a second pendulum assembly having a second pivot coupled to the carriage assembly, wherein the first pivot is coupled to the forward pendulum arm frame member and the second pivot is coupled to the rearward pendulum arm frame member, wherein, relative to a direction of travel of the vehicle, the second pivot is coaxial with the first pivot along a longitudinal axis that is parallel to the direction of travel of the vehicle;
- a first carriage rotation cylinder and a second carriage rotation cylinder coupled between the first and second pendulum assemblies, wherein the first and second carriage rotation cylinders are configured to be repeatedly moveable between locked and unlocked conditions;
- and
- the elongate carriage frame having opposed left and right ends and extending along an axis that is transverse to the direction of travel of the vehicle, wherein the second pendulum assembly is coupled to the first lengthened carriage frame member and the first pendulum assembly is coupled to the second lengthened carriage frame member of the elongate carriage frame, and wherein the carriage assembly, the first pendulum assembly and the second pendulum assembly move in simultaneous free pendulation about the longitudinal axis in a same direction.
