ツチ装置。[Claims for Utility Model Registration] (1) A hitch frame 5 is attached to the rear of the tractor via a three-point link, and an intermediate shaft 15 is connected to a yoke joint 13 connected to a PTO shaft 12 of the tractor.
is supported on the hitch frame 5 via a bullet 22, a working machine is connected to the hitch frame 5, and the intermediate shaft 15 and the input shaft 27 of the working machine are interlockedly connected. The shaft 15 is formed hollow, and a connecting body 28 is fixed to the input shaft 27, with a centering body having a tapered joint part inside the hollow part that is pushed out and urged by a bullet 22.
A centering body that fits into the tapered joint is provided at the front part of the intermediate shaft 15, and the rear part of the intermediate shaft 15 is connected to an internal gear 31 having a small module and tooth traces in the front-rear direction.
The outer peripheral part of the connecting body 28 is connected to the internal gear 31.
A hitch device for a tractor, characterized in that external gears 32 mesh with each other, and opposing end surfaces of the teeth of these gears are chamfered in a chevron shape. (2) The front outer periphery of the connecting body 28 is divided into a ring-shaped external gear 33 and fixed so as to rotate approximately by the module, and the end of the tooth adjacent to this ring-shaped external gear 33 is fixed. 2. The hitch device for a tractor according to claim 1, wherein the teeth are chamfered into a chevron shape.
