The present invention comprises multiple embodiments of an automated, dynamic cover plate system, which may be quickly attached, detached and adjusted to the exterior of a concave grate of a combine harvester in order to adjust the flow characteristics of the concave or separator grate assemblies. The automated, dynamic cover plate system improves the threshing capability of the rasp bar threshing cylinder while simultaneously capturing additional threshed grain. The automated, dynamic cover plate system of the present invention is designed to be controlled, either manually or automatically, by the operator of the combine harvester or by a computerized or automated intelligence system.

The present application for patent of invention refers to a device designed to thresh agricultural products. The agricultural products it is designed to process include grains in general, particularly peanuts and beans, but not limited thereto, and can be applied to other similar crops. The invention comprises a cylinder (1) that has a larger diameter zone (2) and smaller diameter zone (3), said larger or smaller diameter zones intermediated by a transition zone (4); in the smaller diameter zone (3) the helical path is contoured by rigid scale-like components (6) as far as part of the transition zone (4), where flexible elements are applied (7) following the entire length of the larger diameter zone (2), completing the (1) cylinder or rotor, and the flexible elements (7) can be arranged in consecutive way or interspersed, so that the interval between the flexible elements (7) is intermediated by substantially upside-down U-shaped elements (7B).

A concave grate, concave bar, or concave rod assembly and configuration for threshing operations of a combine harvester is disclosed having concave bars or rods configured at various angles and positions such that they maximize threshing throughput. T concave bar assembly can include an elongated bar having a semi-cylindrical or partially round configuration. Further, the elongated bar can include a partial cut-out, notch, or channel longitudinally extending the length of the elongated bar, and wherein the elongated bar can be configured to be secured to a concave of the combine harvester. Here, the partial cut-out, notch, or channel further can include a first sloped or raised surface. Further, the first sloped or raised surface can be configured to make contact with one or more grains of a crop material, thereby effectively and efficiently separating the the one or more grains from the crop material.

A concave assembly for an agricultural machine includes a frame pivotally connected to a structural component and a concave connected to the frame. The frame includes a trunnion having a front end and a rear end. A front arm and a rear arm are connected to the trunnion. A crossbar extends between the front arm and the rear arm. A rotating member rotatably connected to the crossbar. The concave includes a first outer support and a second outer support. An inner support is positioned between the first outer support and the second outer support. A plurality of separator bars extend between the first outer support and the second outer support.
