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.
The rotary converter can be thought of as a motor–generator, where the two machines share a single rotating armature and set of field coils. The basic construction of the rotary converter consists of a DC generator (dynamo) with a set of slip rings tapped into its rotor windings at evenly spaced intervals. When a dynamo is spun the electric ...
In 1977, International Harvester introduced the first Axial-Flow rotary combine. 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.
In 1989, Deere replaced the 6620, 7720, and 8820 with a new line of completely redesigned 'Maximizer' combines that included the 9400, 9500, and 9600 walker combines. These combines featured a center-mounted cab, rear-mounted engine, and more comforts in the cab. Also in 1989, Deere was inducted into the National Inventors Hall of Fame. In 1997 ...
The cam can be seen as a device that converts rotational motion to reciprocating (or sometimes oscillating) motion. [clarification needed] [3] A common example is the camshaft of an automobile, which takes the rotary motion of the engine and converts it into the reciprocating motion necessary to operate the intake and exhaust valves of the cylinders.
It was the disadvantages of the rotary combine (increased power requirements and over-pulverization of the straw by-product) which prompted a resurgence of conventional combines in the late nineties. Perhaps overlooked but nonetheless true, when the large engines that powered the rotary machines were employed in conventional machines, the two ...
Prosecutors said that with the help of an accomplice identified as Sheqir K., Shahraban lured Khadidja into a trap by pretending to offer her a free cosmetic treatment. For a time, authorities ...
A combine harvester combines the reaping (plus or minus binding), threshing, and winnowing functions into one machine, hence the "combine" part of its name. To that list, the Baldwin brothers' Gleaner added self-propulsion. Earlier combines, the so-called pull-type or tractor-drawn combines, were towed by tractors.
