【 摘 要 】

The chopped roller is the main working part of green fed harvester, of which performance directly affects the cutting effect and power consumption of the machine. A new type hob-type closed chopped roller is designed because of the large cutting resistance of the harvester, and the blade on the roller is arranged in a double row herringbone. It does dynamics analysis for chopped roller and gets three affect parameters, they are cutting speed, sliding cutting angle and grinding blade angle. Under the condition that the blade sharp degree is consistent, take the cutting resistance torque as test aim, the influence of cutting speed, sliding cutting angle and grinding blade angle to cutting resistance torque was studied by using orthogonal test of secondary rotation, the main order of the influence of each factor on the index is cutting speed > grinding blade angle > sliding cutting angle. When the cutting speed is 1200 r/min, sliding cutting angle is 25°, grinding blade angle is 25° which is the best parameter combination for the cutting resistance torque. The experimental results provide data support for further optimization of the chopped roller.
