Removable concave threshing bars for an agricultural combine
First Claim
1. A concave for an agricultural combine, comprising:
- a frame assembly, the frame assembly includes a first frame connected to a second frame for movement between an open position and a closed position relative to the second frame;
the first frame includes curved members axially spaced from one another;
threshing bars;
an engagement assembly non-destructively connects each of the threshing bars to the curved members of the first frame, the threshing bars are spaced from one another and extend axially between the curved members forming openings therebetween for grain to pass through;
the threshing bars are non-destructively connected to the first frame via the engagement assemblies, when the first frame is in the open position relative to the second frame and when the first frame is in the closed position relative to the second frame;
the engagement assemblies allow independent non-destructive removal of the threshing bars relative to one another from the first frame, when the first frame is in the open position relative to the second frame; and
the second frame restrains independent non-destructive removal of the threshing bars relative to one another from the first frame via the engagement assemblies, when the first frame is in the closed position relative to the second frame.

Abstract
A concave for an agricultural combine includes first and second frames connected together for movement between closed and open positions. The first frame includes curved members axially spaced from one another, and bars each movable between a first position removably connected to the first frame and a second position detached from the first frame, wherein the bars are spaced from one another and extend axially between the curved members forming openings therebetween for grain to pass through in the first position of each of the bars. The second frame restricts movement of each of the bars between the first and second positions in the closed position of the first and second frames, and the second frame allows movement of each of the bars between the first and second positions in the open position of the first and second frames.

7. A concave for an agricultural combine, comprising:
-
a frame assembly, the frame assembly includes a first frame connected to a second frame for movement between an open position and a closed position relative to the second frame; the first frame includes curved members axially spaced from one another; threshing bars, the threshing bars each include a separating grate; an engagement assembly non-destructively connects each of the threshing bars to the curved members of the first frame, the threshing bars are spaced from one another and extend axially between the curved members forming openings therebetween for grain to pass through, and the separating grate of each one of the threshing bar extends across an adjacent one of the openings for separating grain from threshed crop material; the threshing bars are non-destructively connected to the first frame via the engagement assemblies, when the first frame is in the open position relative to the second frame and when the first frame is in the closed position relative to the second frame; the engagement assemblies allow independent non-destructive removal of the threshing bars from the first frame, when the first frame is in the open position relative to the second frame; and the second frame restrains independent non-destructive removal of the threshing bars relative to one another from the first frame via the engagement assemblies, when the first frame is in the closed position relative to the second frame. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A concave for an agricultural combine, comprising:
-
a first frame includes curved members axially spaced from one another; threshing bars; an engagement assembly non-destructively connects each of the threshing bars to the curved members of the first frame, the threshing bars are spaced from one another and extend axially between the curved members forming openings therebetween for grain to pass through; a second frame; the engagement assemblies allow independent non-destructive removal of the threshing bars relative to one another from the first frame, when the second frame is spaced apart from the first frame; and the second frame restrains independent non-destructive removal of the threshing bars relative to one another from the first frame via the engagement assemblies, when the second frame is juxtaposed relative to the first frame; wherein the threshing bars are non-destructively connected to the first frame via the engagement assemblies, when the second frame is spaced apart from the first frame and when the second frame is juxtaposed relative to the first frame. - View Dependent Claims (15, 16, 17, 18)
