Design and Experimental Study of a Mower Conditioner Drive System

Abstract:

According to the forage of mountain region harvesting requirements, a transmission of montanic mower conditioner was designed. The drive system was combined with automatic tension sprocket and double chain wheel of upper and lower crushers, firstly, to realize the automatic regulation and relative motion of two flattening roller, secondly, the power was passed to reel device and achieved forage feeding function; the off-center slider crank mechanism drove the horizontal header to realize the grass cutting function. Through the theoretical analysis and experimental study of the system working performance, applied comprehensive scoring method to obtain the optimal combination of working parameters: the cutting ration was3, the press roller circumferential speed was 4.5m/s, the reel speed ratio was 3. Measured with the optimal combination of operational parameters, the results showed that: the working stubble was 40mm, the recutting rate was 0.8%, the flattening ratio was 42.8% and the crushed grass loss rate was 2.3%, which could meet the demand of forage harvest operation.
