摘要

PPROBLEM TO BE SOLVED: To facilitate exchange of each ditching wheel in a ditching wheel-driving apparatus of a no-tilling direct sowing machine. PSOLUTION: The ditching wheel-driving shaft B constituting the ditching wheel-driving shaft apparatus A is divided into three bodies of a driving shaft body 16 in which many ditching wheels W are externally fitted at prescribed intervals in axial direction, a driving shaft-connecting body 19 inserted into the driving shaft body 16 and a pair of divided bodies 17a and 17b of driving shaft connected to a driving means installed in a machine body K, and large-sized connecting flange parts 18 and 25 larger than the driving body 16 are installed in the end of the driving shaft body 16 and the end of the driving shaft-connecting body 19 and each connecting flange part 32 is installed in the inner ends of a pair of divided bodies 17a and 17b of the driving shaft, and the connecting flange part 18 of the end of the driving shaft body 16 is connected to the connecting flange part 32 of the divided body 17a of the driving shaft on the driving side corresponding to the connecting flange part 18 by each connecting bolt 23, and the connecting flange part 25 of the end of the driving shaft-connecting body 19 is connected to the connecting flange part 32 of the divided body 17b of the driving shaft on the side to be driven corresponding to the connecting flange part 25.
