Study on Wire Type Sugarcane Stripping Machine (I)

Abstract

Wire type sugarcane stripping machine shown in Fig. 1 was experimented to improve the useful life of stripping wire with changing single wire diameter, fixing method of wire and rotating speed of stripping drum. To evaluate the effect of single wire diameter, rotating speed of stripping drum and stripping pitch on the rate of trash, broken mature stalks and broken immature tops, field tests were done on sugarcane variety Nco 310, The results obtained are as follows.
(1) The useful life of wire was affected mainly by the fixing method of wire, rotating speed and the lap. The fixing method shown in Fig. 2 (b) revealed longer life of wire than Fig. 2 (a).
(2) We can use single wire 1.04mm in diameter without bruising and shredding of cane.
(3) As the rotating speed of stripping drum increased the rate of broken immature tops and broken mature stalks increased, but the rate of trash and the useful life of wire decreased.
(4) An increase in stripping pitch did not affect the rate of broken mature stalks, but decreased the rate of trash.
(5) In this machine, it was not enough to separate trash detached from the stalks.
(6) The wire rapes should be replaced after stripping about 35 tons of cane, and the useful life of wire was about from sixty to seventy hours.
