Abstract
A sieve for use in an agricultural harvester includes a framework with a pair of opposed side members. A plurality of overlapped louvres extend between the pair of opposed side members and are overlapped relative to each other. The opposed side members are each comprised of an extruded metal side member with a partially open elongate channel having a predefined cross section, and a polymeric strip having a mating cross section carried within the elongate channel.
Claims17
A sieve for use in an agricultural harvester, the sieve comprising:
- a framework including a pair of opposed side members, wherein each of the opposed side members are comprised of (i) an extruded metal side member with a partially open elongate channel having a predefined cross section, and (ii) a strip having a mating cross section carried within the partially open elongate channel, wherein the partially open elongate channel has an open side and an opposing closed side, and the strip includes a hole that is aligned with a hole in the closed side, and wherein the aligned holes extend generally orthogonally from the open side and are spaced apart from each other;
- and
- a plurality of overlapped louvres extending between the pair of opposed side members, being overlapped relative to each other, and facing the open side of the partially open elongate channel, wherein the plurality of louvres each include a wire and a plurality of fingers attached to the wire, wherein one of the wires is rotatably carried within the aligned holes.
A method of assembling a sieve for use in an agricultural harvester comprising the steps of:
- inserting a strip within an elongate channel of an extruded metal side member, wherein the elongate channel has an open side and an opposing closed side, and the strip includes a hole that is aligned with a hole in the closed side, and wherein the aligned holes extend generally orthogonally from the open side and are spaced apart from each other;
- deforming a deformable lip of the extruded side member to fix the strip within the elongate channel;
- drilling holes through both the strip and the extruded side member. wherein the holes are aligned with each other;
- and
- mounting a rotatable louvre to the extruded metal side member by positioning a wire of the louvre through the aligned holes in the closed side and the strip such that the louvre faces the open side of the elongate channel.
