SPRAYER FLUID OPERATION SYSTEM

摘要

Embodiments of a spray fluid operation system include a fluid flow circuit that provides several sprayer features while using a minimum number of fluid pumps. In an agricultural setting, a first pump (one function of which is filling) is integrated with a second pump (one function of which is spraying) and both located compactly underneath the solution tank. In some embodiments that include only two pumps, they are centrifugal impeller pumps. Each of the two pumps is capable of performing more than one function. Together, they provide self-primed filling, auto dilution, eductor rinsing, and so on, in a fluid-isolated manner to avoid fluid contamination.

主权项

1. A fluid application system comprising:
a tank that holds a spray solution, wherein the tank is flow-coupled to a filling device, a circulating device, a discharge device, and a rinsing device; wherein the filling device adds the spray solution to the tank; wherein the circulating device agitates the spray solution through the tank; wherein the discharge device releases the spray solution from the tank; wherein the rinsing device empties the spray solution from the tank; a self-priming pump and a non-self-priming pump; wherein the self-priming pump operates the filling device and the rinsing device; wherein the non-self-priming pump operates the circulating device and pumps the spray solution for spraying; wherein the non-self-priming pump is located below the tank for the spray solution to flow to the non-self-priming pump by gravity; wherein the filling device is fluid-isolated from the circulating device and the discharge device; and wherein the discharge device includes at least one of a spray nozzle, a spray boom, the circulating device and the non-self-priming pump.
