When it comes to concaves, there are several options to choose from. Being blessed with a great abundance of various crops throughout all the productive agricultural regions, you may now want that perfect aftermarket combine concaves, which add to the productivity of harvest by reducing grain wastage. You can select a custom matched to best fit a specific application to attain best performance in any weather conditions.
On average, concave are a little heavier than original, and its strength and durability is defined with thicker cross bars, wires, side plates, and back braces. These features provide improved versatility for various applications and last longer. The raw materials that make up concaves for combines are judged by their precision of mechanics and assembly. The manufacturers strive to bring consistent dimensions for adequate installation that gives quality threshing surface.
What are the Different Types of Concave for Combines?
The conventional concaves feature a line bored threshing surface with truly level bar surface from side to side. Here the wire holes also drilled than punched to offer a tight fit to prevent spearing and trapping of straw. The aftermarket combine concave work for crops on any conditions and are usually “one size that fits all” category or at least most of the crops harvested. These can be used for heavy duty harvesting as well for lesser amount of crops, in equally satisfying output.
Wide wire concaves are intended for soybeans, corns and other large grain crops such as rice, sunflowers and sorghum. The wide wire concave for combines are equipped with wires perpendicular to the strong cross bars. These have a wider gap to enable more space for larger material for threshing.
A helical bar concaves the solution for more aggressive threshing. As the wires and cross bars and are diagonal in a helical bar concave, the material going in the rotor strikes the concave at the right angle, preventing un-threshed grains and whiteheads.
What is a Rotary Concave?
Rotary concave are available in different configurations according to particular series of combine they fit. A variety in moisture level, crop type, and desired sample quality will determine which aftermarket combine concave you should purchase. However, you must analyze your needs for a certain combine before buying one. Narrow wire ones are the standard choice for wheat, barley, canola, oats and cereal crops or fine seeds, but not recommended for corn.
Concave Plates, Shock Kits and Inserts
Concave cover plates may be necessary in situations where it is difficult to thresh crops. It will improve distribution of material across the entire width of the shoe augers. Also, it can reduce whiteheads. One or two cover plates need to be installed on the first, second and the third concave, if required. With the extent of options available, you can fine tune the effective operation of these plates and combine concaves.
Concave shock kits reduce damage to pipes, concave, and the rotor. Concave inserts enhance threshing and prevent corn cobs with un-threshed kernels from getting through open areas at the backside of some concaves.
