Abstract
A boom spray assembly, such as for an agricultural sprayer, has a feed pipe and a spray pipe with a continuous tubular body. The tubular body has at least one facial feed opening therein between the ends opening along a second axis at an angle to a first axis of the tubular body. A saddle fitting is coupled to the spray pipe that defines a first passageway extending along the first axis to receive the tubular body and defines a second passageway extending along the second axis in registration with the at least one facial feed opening and receiving spray material from the at least one feed pipe. At least one spray nozzle is coupled to the tubular body of the at least one pipe in communication with the first and second passageways.
Claims18
In a sprayer having a boom frame, a spray assembly mounted to the boom frame comprising:
- at least one feed pipe operationally coupled to a spray material supply;
- at least one spray pipe having a unitary tubular body including an internal passageway extending along a first axis between opposite ends, the tubular body having at least one facial feed opening formed in the tubular body between the ends and opening about a second axis at an inclined angle to the first axis and having at least one facial nozzle opening formed in the tubular body between the ends;
- and
- at least one saddle fitting mounted to the tubular body of the at least one spray pipe and to the at least one feed pipe, the at least one saddle fitting defining a first passageway extending along the first axis and receiving the tubular body and including a saddle fitting opening defining a second passageway extending along the second axis, wherein the saddle fitting opening is in registration with the at least one facial feed opening and is configured to transfer spray material from the at least one feed pipe;
- at least one nozzle coupled to the tubular body of the at least one spray pipe at the at least one facial nozzle opening and in communication with the first and second passageways, and
- an aspirator at least in part received within and extending into an open end of the tubular body of the at least one spray pipe.
A sprayer, comprising:
