Forage harvest is an important part in the production of grass industry , to improve the the forage harvesting mechanization level and productivity , harvest is extremely important to ensure grass industry . The cutter is part of the important work of the various forage harvesting machinery . Currently, a variety of forage harvesting machinery commonly used in both reciprocating and rotary cutter . The rotary cutter is no support cutting does not produce clogging simple replacement blade . The research design double disc mower , the choice of a rotary cutter , adaptability forage , particularly adapted to dense lodging and wrapped around the pasture even , steady work , and high productivity. This issue through analysis of domestic and foreign forage harvester research , mechanical design principles and methods to optimize the design , developed dual disc mower several innovative points : First , the equipment before hanging by a small four-wheel tractor job , the main hook , lift , drive , cutting and other institutions , the design is simple , compact , adaptable , and low cost ; Second, the machinery of the lift from the tractor hydraulic handle manipulation by the lift arm , wire ropes , pulleys and other institutions lifting rod, completed equipment level lift ; , power passed by a tractor flywheel Machines pulley arrangement in the middle of the two gearboxes , two pulleys in the same plane , more compact ; equipment front-end to set the fence shield , the cutterhead is made ??into the dish, so that the blade is rotated into a certain angle with the ground , and the fall off or fly without wounding , safe and reliable . The main transmission part of the machinery of mechanical analysis and checking calculation . The experiments show that the equipment has strong applicability , reasonable structure , excellent performance , high production efficiency .
