RESEARCH AND DEVELOPMENT OF POWER DETECTION TECHNOLOGY AND DEVICE FOR KEY PARTS OF GREEN FODDER HARVESTER.

The study focuses on the self-propelled forage harvester and analyzes various parameters such as the working speed and torque of the cutting table, chopped roll, throwing fan, walking parts, and the output flow rate and pressure of the hydraulic pump of the feeding section. Field experiments show that the fan, walking, chopping roller, and grain crushing roller drive powers account for 7-8%, 7-10%, 24-28%, and 13-21% of the engine power, respectively. The driving power of the inner and outer sides of the cutting table, fan, and walking power account for a relatively stable proportion of the engine output power. The study collects and analyzes operation parameters simultaneously to provide a reference for evaluating the performance and optimizing the design of corn forage harvesters. [ABSTRACT FROM AUTHOR]
