Case IH 7140 rotary harvester with corn header with cutaway showing rotary threshing mechanism. Case IH axial-flow combines (also known as rotary harvesters) are a type of combine harvester that has been manufactured by International Harvester, and later Case International, Case Corporation, and CNH Global, used by farmers to harvest a wide range of grains around the world.
Case IH history began when, in 1842, Jerome Case founded Racine Threshing Machine Works on the strength of his innovative thresher. In 1869 Case expanded into the steam engine business and, by 1886, Case was the world's largest manufacturer of steam engines.
Case harvester, 20+ mule team Case IH Axial-Flow combine. Combines, some of them quite large, were drawn by mule or horse teams and used a bullwheel to provide power. Later, steam power was used, and George Stockton Berry integrated the combine with a steam engine using straw to heat the boiler. [8]
This machine, produced at East Moline, Illinois, was the first generation of over 30 years of Axial-Flow combines. In 1979 IH introduced two tractors, the 3388 and 3588, known as the 2+2 4WD line. These were built by taking two 1086 rear ends and hooking them together with a transfer case.
August 1911 A Case row-crop model, circa 1940s Case Model 830 Case Model 2090. The Case Corporation was a manufacturer of agricultural machinery and construction equipment. Founded, in 1842, by Jerome Increase Case as the J. I. Case Threshing Machine Company, it operated under that name for most of a century. For another 66 years it was the J ...
So, no work is done. Leakage, and its interaction with other losses in the flow field, is complex; and hence, at the tip, it has a more pronounced effect than secondary flow. Leakage-flow induced three-dimensionality, like the mixing of leakage flow with vortex formation, entrainment process, diffusion and convection.
Axial flow turbomachines - When the path of the through-flow is wholly or mainly parallel to the axis of rotation, the device is termed an axial flow turbomachine. [9] The radial component of the fluid velocity is negligible. Since there is no change in the direction of the fluid, several axial stages can be used to increase power output.
An axial-flow pump for industrial use. An axial-flow pump, or AFP, is a common type of pump that essentially consists of a propeller (an axial impeller) in a pipe.The propeller can be driven directly by a sealed motor in the pipe or by electric motor or petrol/diesel engines mounted to the pipe from the outside or by a right-angle drive shaft that pierces the pipe.
