Concaves for an agricultural combine
First Claim
1. A concave for an agricultural combine, comprising:
- a first frame;
a second frame movable between a first position spaced apart from the first frame and a second position juxtaposed on either side of the first frame;
a threshing mat, the threshing mat comprises threshing bars each including a separating grate, and an engagement assembly non-destructively connecting each of the threshing bars to the first frame, wherein the threshing bars form openings therebetween for grain to pass through, the separating grate of each of the threshing bars extends across an adjacent one of the openings for separating grain from threshed crop material, and the separating grate of each of the threshing bars is fixedly connected to an adjacent one of the threshing bars; and
the engagement assemblies allow non-destructive removal of the threshing mat from the first frame, when the second frame is spaced apart from the first frame, and the threshing mat remains non-destructively connected to the first frame via the engagement assemblies and the second frame interacts with the threshing mat on either side of the first frame alone restraining non-destructive removal of the threshing mat from the first frame via the engagement assemblies, when the second frame is in the second position juxtaposed on either side of the first frame.

Abstract
A concave for an agricultural combine includes first and second frames and a threshing mat that includes threshing bars each including a separating grate. An engagement assembly non-destructively connects each of the threshing bars to the first frame, the threshing bars form openings therebetween for grain to pass through, the separating grate of each of the threshing bars extends across an adjacent one of the openings for separating grain from threshed crop material, and the separating grate of each of the threshing bars is fixedly connected to an adjacent one of the threshing bars. The engagement assemblies enable non-destructive removal of the threshing mat from the first frame, when the second frame is spaced apart from the first frame. The second frame restrains non-destructive removal of the threshing mat from the first frame via the engagement assemblies, when the second frame is juxtaposed to the first frame.

9. A method of assembling a concave for an agricultural combine, comprising:
-
providing a first frame, threshing bars each including a separating grate, and a second frame movable between a first position spaced apart from the first frame and a second position juxtaposed on either side of the first frame, the second frame being in the first position; non-destructively connecting each of the threshing bars to the first frame via an engagement assembly thereby allowing non-destructive removal of the threshing bars from the first frame via the engagement assemblies while the second frame is in the first position, the threshing bars being spaced apart forming openings therebetween for grain to pass through, and the separating grate of each of the threshing bars extends across an adjacent one of the openings for separating grain from threshed crop material; and moving the second frame from the first position to the second position on either side of the first frame and fixedly connecting the separating grate of each of the threshing bars to an adjacent one of the threshing bars forming a threshing mat from the threshing bars while leaving the threshing bars of the threshing mat non-destructively connected to the first frame via the engagement assemblies, the second frame thereby interacting with the threshing mat on either side of the first frame alone restraining non-destructive removable of the threshing mat from the first frame via the engagement assemblies. - View Dependent Claims (10, 11, 12)

13. A method of assembling a concave for an agricultural combine, comprising:
-
providing a first frame, threshing bars each including a separating grate, and a second frame movable between a first position spaced apart from the first frame and a second position juxtaposed on either side of the first frame, the second frame being in the first position; non-destructively connecting each of the threshing bars to the first frame via an engagement assembly thereby allowing non-destructive removal of the threshing bars from the first frame via the engagement assemblies while the second frame is in the first position, the threshing bars being spaced apart forming openings therebetween for grain to pass through, and the separating grate of each of the threshing bars extends across an adjacent one of the openings for separating grain from threshed crop material; and moving the second frame from the first position to the second position on either side of the first frame, removably catching the threshing bars to the second frame via non-destructive removable catch connections, and fixedly connecting the separating grate of each of the threshing bars to an adjacent one of the threshing bars forming a threshing mat from the threshing bars while leaving the threshing bars of the threshing mat non-destructively connected to the first frame via the engagement assemblies, the second frame thereby interacting with the threshing mat on either side of the first frame alone restraining non-destructive removable of the threshing from the first frame via the engagement assemblies. - View Dependent Claims (14, 15, 16, 17)

18. A method of assembling a concave for an agricultural combine, comprising:
-
providing a frame, threshing bars each including a separating grate, and stops movable between a first position spaced apart from the frame and a second position juxtaposed on either side of the frame, the stops being in the first position; non-destructively connecting each of the threshing bars to the frame via an engagement assembly thereby allowing non-destructive removal of the threshing bars from the frame via the engagement assemblies while the stops are in the first position, the threshing bars being spaced apart forming openings therebetween for grain to pass through, and the separating grate of each of the threshing bars extends across an adjacent one of the openings for separating grain from threshed crop material; and moving the stops from the first position to the second position juxtaposed on either side of the frame and fixedly connecting the separating grate of each of the threshing bars to an adjacent one of the threshing bars forming a threshing mat from the threshing bars while leaving the threshing bars of the threshing mat non-destructively connected to the frame via the engagement assemblies, the stops thereby interacting with the threshing bars on either side of the frame alone restraining non-destructive removal of the threshing mat from the frame via the engagement assemblies. - View Dependent Claims (19, 20, 21)
