Abstract
The combine is a machine used to harvest, thresh, and clean grains from a variety of crop and field conditions. The main purpose of combine harvesting is to recover grain with a minimum grain loss, grain damage, and power requirement. The objective of this research was to investigate the influence of inertia momentum of threshing cylinder on power consumption. The power required by the threshing drum can be expressed as the summation of power to operate a machine with no material and power to process material. The power required to process material will vary with many variables: volume flow rate of material, concave clearance and length, cylinder speed, number of bars on the cylinder etc. Experimental results shown, that the rotation frequency and momentum of inertia of the threshing cylinder influence to power consumption for its rotation. With the increase the momentum of inertia of the threshing cylinder from I = 8.34 kgm2 to I = 15.73 kgm2, the power requirement for idle running of threshing cylinder increase about 0.1 kW. When the feederate is changes from 4 kgs-1 to 14 kgs-1, the power consumption for threshing of corn cobs increases from 2.5 kW to 7.7 kW.
