EXPERMENTAL STUDY RESULTS ON THE LEAF PEELING COMPONENT

OF THE SUGARCANE COMBINE HARVESTER

Ta Hanh ', Luong Van Vuot ^ Do Huu Khi'

SUMMARY

This paper shows the study results on working regime of a leaf peeling component in the sugarcane

combine harvester. Based on single- and multi-factor experiments, with the control conditions of unpeeled

leaf ratio TI (xO) < 5% and damaged ratio of sugarcane trunk 4' (xO) < 1%, values of parameters are

determined as following: rotation ofthe leaf peeling roller nt = 872.745 rpm; rotation ofthe plant gripping

roller njt = 267.075 rpm; height ofthe peeling ribs lc = 97.791 mm; and load factor q = 4.87515 kg.s"'.

Operating with this regime, the sugarcane leaf peeling component gives minimum specific energy

consumption of Ne = 970.83 W.kg-j. The parameters' values determined shell be the basis for designing of

theleaf peeling component ofthe 15 to 17 tons.h' sugarcane combine harvester.

Keywords: peeling component, combine harvester, peeling roller, peeling ribs.
