Abstract
There is provided a cleaning apparatus for unclogging an irrigation emitter inlet filter by dislodging or crushing or breaking a trapped solids. In some embodiments, a ram pushes the trapped solids out of a fluid inlet of the emitter. In other embodiment, a constriction provided for retaining a particle has a changeable interior cross section. By changing the cross section of the constriction, the constriction is unclogged. In alternative embodiments the filtration member may include two rigid members moving in relation one to the other or the filtration member may be elastic. In further alternate embodiments the cleaning may be activated automatically or manually.
Claims17
A drip irrigation apparatus to be attached to an irrigation hose with an inlet entrance inserted into the hose and with a body located outside the hose, the body including a drip outlet, the apparatus comprising:
- a) a conduit having a proximal end moveably connected to the body via a screw thread and a distal end including the inlet entrance, said conduit including:
- a step located on an exterior of said conduit between said inlet entrance and said proximal end connected to said body, wherein the exterior of said conduit is wider on a distal side of said step than on a proximal side of said step, said step sized and shaped for insertion through the wall of the irrigation hose into the irrigation hose for preventing elimination of the inlet entrance from the irrigation hose through the wall, and
- a channel providing fluid communication between said inlet entrance and said body,
- b) a ram, at least a portion of said ram shaped and positioned to move longitudinally inside said channel between said step and said inlet entrance to eject a particle located between said ram and said inlet entrance out from said inlet entrance into said irrigation hose, wherein said ram includes an elongated member rigidly attached to said body and long enough to pass through said channel to reach said inlet entrance, wherein a tip of said ram is configured to extend out said inlet entrance into said irrigation hose,
- c) a handle for rotating said conduit with respect to said screw thread via human manipulation thereby moving said conduit longitudinally with respect to said ram for said ejecting.
