ЗАДАНИЕ № 23 (- выберите один вариант ответа)
Прочитайте текст и выполните задания
1. As the combine moves through the field, the gatherer points are positioned between the cornrows. The stalk rolls pull the cornstalks down so the deck plates will snap off the ears. Trash knives prevent weeds and trash from wrapping around the stalk rolls. The gatherer chains move the ears up to the auger. The auger moves the ears to the front of the feeder house where rubber paddles feed the ears into the feeder house. It costs time and money if the gatherer row components are worn or not properly maintained. Worn gatherer row components may result in: stalk roll wrapping, row unit plugging, feeder house plugging, ear loss, pulling up of cornstalks, kernel damage. Two critical parts that affect productivity on a corn head are the stalk rolls and gatherer chains.
2. The stalk rolls are formed from nodular iron and then placed in an automatic welding machine that hard-faces the surface of the stalk roll flutes. This ensures longer life for the stalk roll, season after season. On a new stalk roll, the flutes are straight. As the flute becomes worn, it becomes concave at the rear of the stalk roll. This concave shape will not allow the roll to aggressively pull the stalk downward and strip the ear from the stalk.
3. The fluted stalk rolls are designed with a more aggressive stalk-stripping action for increased feeding capacity in down or weedy crops. The straight flutes provide a tighter working area (outer edge of flute to body of adjacent stalk roll) to produce a more aggressive feeding action. The full-length flutes also provide a 55 percent longer crop engagement area between the rolls to allow for faster pull-through action.
4. Efficient corn harvesting depends on the strength and capacity of the corn head gatherer chain. The gatherer chain acts as a conveyor system to move the ears into the auger. Embossments in the sidebars and the flight lugs of the chain protect the connecting pinheads. Without these raised areas, the connecting pinheads would be exposed to excessive wear, resulting in premature chain failure. The face of each flight is extended down to create a lip between the sidebars. The lip prevents debris from collecting at the roller, and reduces drag and wear to the chain and sprockets. The flight face slants at a 15-degree angle away from the roller chain. This slight angle creates a self-cleaning effect as the flight moves the ears toward the auger. Every element of the chain-pins, bushings, flights, roller, and sidebars - is heat-treated for strength and long life.
