Wear resistant granular direction altering device
The invention provides a pneumatic conveying system having a series of supply lines with at least portions of the lines being wear resistant to extend the useful lifespan of an agricultural product delivery applicator. The wear resistant supply line(s) may be made from a hard material and have a curve(s) defined by angled or mitered segments that are welded or otherwise joined to collectively provide the curve(s) The wear resistant supply lines may be at least partially reinforced by way of, for example, welded or other build up wear resistant material(s) at high wear zones of the supply lines.
1. An agricultural application implement comprising:
a plurality of wheels supporting a frame;
a pneumatic conveying system supported by the frame for applying particulate matter, the pneumatic conveying system comprising:
at least one fan directing air flow through at least one plenum, the air flow being further directed through the at least one plenum into at least one primary supply line;
the at least one primary supply line including at least one straight segment and at least one curved segment;
an inner surface of at least a portion of the at least one curved segment having a greater wear resistance than the at least one straight segment as a wear-resistant portion of the at least one curved segment, wherein the inner surface of the at least a portion of the at least curved segment includes a series of filler metal lines defined by a series of weld beads comprising a wear-resistant steel weld electrode, and wherein the weld beads are applied in multiple layers to define a multi-layer wear-resistant portion of the at least one curved segment.
2. The agricultural application implement of claim 1 , wherein the multi-layer wear-resistant portion of the at least one curved segment includes at least three layers of weld beads.
3. The agricultural application implement of claim 1 , wherein the series of filler metal lines extend across only an inner surface of an outer radius of the curved segment.
4. The agricultural application implement of claim 3 , wherein the curved segment curves to define an angle of direction change of at least 75-degrees.
5. The agricultural application implement of claim 4 , wherein the curved segment curves to define an angle of direction change of at least 90-degrees.
6. The agricultural application implement of claim 5 , wherein the curved segment curves to define an angle of direction change of at least 100-degrees.
7. An agricultural application implement for applying particulate matter comprising:
a plurality of wheels supporting a frame;
a pneumatic conveying system supported by the frame with the pneumatic conveying system comprising:
at least one fan directing air flow through at least one plenum, the air flow being further directed through at least one plenum into at least one primary supply line, wherein the at least one primary supply line including a straight segment and a curved segment defined by a segmented elbow, the segmented elbow comprising:
at least two miter sections, each miter section including an inner miter side extending from a first miter section end to the second miter section end, each miter section further including an outer miter side located and positioned opposite from the inner miter side, the outer miter side being of greater length than the inner miter side;
each miter section being joined to at least one additional miter section, the outer miter side of a first miter section being adjacent to and abutting the outer miter side of a second miter section when joined;
at least one of the miter sections is made from a material with a greater wear resistance value than the straight segment of the primary supply line; and
wherein the segmented elbow curves to define an angle of direction change of at least 75-degrees and wherein adjacent miter sections are externally welded to each other about their respective outer circumferential surfaces.
8. The agricultural application implement of claim 7 , wherein each of the miter sections is made from a material with a greater wear resistance value than the straight segment of the primary supply line.
