RAKING IN-DRIVING UNIT OF ROLL BALER

PROBLEM TO BE SOLVED: To provide a raking in-driving unit of a roll baler for reducing a residual culm amount by providing its constitution for intermittently connecting and cutting off the power transmission to the raking-in unit singly, arranging a belt clutch for preventing an inferior action due to dusts between a transmission and a counter shaft and also rotating the raking in unit synchronized with its working speed. SOLUTION: This raking in-driving unit is provided by outputting an input of the raking in unit 1 installed as transversed at the tip of a roll baler from a transmitting shaft 8 of the transmission M, synchronizing the rotation of the raking in unit 1 with a traveling speed, installing belt clutch B 41 between the shafts with a counter shaft 3, linking a clutch lever 6 for intermittently connecting and cutting off singly as connecting to an operating part B, also extending a raking in chain 17 in an upper space H of a crawler 60, and simultaneously installing an automatic tension for absorbing the extension and contraction of the chain caused by the lifting up and down change with an automatic tension arm 70.
