Abstract
A mobile agricultural machine has a valve controlled to apply liquid material to a field. An application assembly defines a conduit from the valve to a distal application tip. The application assembly includes a distal conduit section that has an inner diameter that is smaller than an inner diameter of a more proximal conduit section, that is closer to the valve, than the distal tip of the application assembly.
Claims20
A mobile agricultural machine, comprising:
- ground engaging elements that carry the machine over a field;
- a valve, having an inlet end configured to be connected to a source of liquid, under pressure, to be applied to the field and an outlet end;
- a pump pumping the liquid from the source to the valve;
- and
- an application assembly having a proximal end connected to the outlet end of the valve and having a distal end through which pulses of the liquid pass to be applied to the field, the application assembly defining a conduit between the proximal end and the distal end, and having a first hose section with a first inner diameter defining a first section of the conduit and a second hose section, with a second inner diameter, smaller than the first inner diameter, defining a second section of the conduit, the second section of the conduit lengthening the pulses of the liquid.

A mobile agricultural machine, comprising:
- a ground engaging element that carries the machine over a field;
- a valve, having an inlet end configured to be connected to a source of liquid, under pressure, to be applied to the field and an outlet end, the valve being controlled with a pulsed control signal;
- and
- an application assembly having a proximal end connected to the outlet end of the valve and having a distal end through which the liquid passes to be applied to the field, the application assembly defining a conduit between the proximal end and the distal end, and having a first hose section with a first inner diameter defining a first section of the conduit and a second hose section, distal of the first hose section, with a second inner diameter, smaller than the first inner diameter, defining a second section of the conduit, distal of the first section of the conduit, wherein the second hose section is configured to retain its inner diameter when the liquid under pressure is in the second section of the conduit.

A mobile agricultural machine, comprising:
- a ground engaging element that carries the machine over a field;
- a valve, having an inlet end configured to be connected to a source of liquid, under pressure, to be applied to the field and an outlet end, the valve being controlled, to be opened and closed, with a pulse width modulated control signal;
- and
- an application assembly having a proximal end connected to the outlet end of the valve and having a distal end through which the liquid passes to be applied to the field, the application assembly defining a conduit between the proximal end and the distal end, and having a first hose section with a first inner diameter defining a first section of the conduit and a second hose section, with a second inner diameter, smaller than the first inner diameter, defining a second section of the conduit distal of the first section of the conduit and having an orifice member disposed on a distal tip of the second hose section, the orifice member defining an orifice with an inner diameter that remains fixed regardless of whether the valve is opened or closed.
