摘要

The efficiency of the reciprocating type cutter bar is influenced by the dynamic cutting force exerted by the cutter bar on the crop. The appropriate crop, machine and operational variables that influence the force required for cutting fodder maize stalks were identified. For recording the dynamic force required for cutting maize stalk, a cutter bar test rig was developed. The investigation was carried out with two levels of stroke length of cutter bar viz., 76.2 and 90.0 mm, three levels of cutter bar speed viz., 1.5, 1.75 and 2.0 ms~(-1), four levels of diameter viz., 10, 15, 20, and 25 mm and three levels of moisture content of maize stalk (completely dry forage, semi dry and green forage). The peak cutting force requirement was directly proportional to diameter and inversely proportional to moisture content of maize stalk and cutter bar speed. The cutter bar with stroke length of 90.0 mm registered 6.3 to 28.7 % reduction in peak cut-rnting force as compared to 76.2 mm stroke length for the selected levels of cutter bar speed, diameter and moisture content of maize stalk. The peak cutting force of 272.4 N was registered for a combination levels of 71.2 % moisture content, 25 mm stalk diameter, 2.0 ms~(-1) cutter bar speed and 90.0 mm stroke length.
