構造を提供することを目的とするものである。 Therefore, in the present invention, the support shaft of the tight pulley arm is constituted by a bolt having a threaded part and a round shaft part under the neck, the boss of the arm is inserted into the round shaft part, and a nut is screwed into the threaded part. The boss is held between the nut and the bolt head, and the threaded portion is passed through the frame and the halved transmission case that make up the machine body, and the nut is tightened. The object of the present invention is to provide a structure for mounting a tight pulley in a mobile agricultural machine that eliminates the above-mentioned drawbacks by fixing the case and fixing the frame and the split transmission case at the same time as attaching the support shaft. It is.

Further, a belt 1 is connected between the output pulley 9 of the engine 5 and a pulley 10 fixed to a shaft protruding from the transmission case 7.
1 is wound around the belt 11, and a tight pulley 12, which constitutes a belt tension clutch, is arranged facing the belt 11. Tight pulley 12
As shown in FIGS. 2 and 3, the arm 13
The arm 13 has a boss 1 at its base end.
5 is fixed, and a pulley 16 is attached to the tip of the
A shaft 14 that rotatably supports the is fixed. The boss 15 is rotatably supported by a support shaft 17 according to the present invention, which includes a threaded portion 17a of a predetermined length and a relatively long round shaft portion 17 under the neck.
It consists of a bolt with b. The arm boss 15 is rotatably inserted into the round shaft portion 17b of the bolt 17, and the nut 19 is screwed into the threaded portion 17a, and the boss 15 is held between the nut 19 and the bolt head 17c. In addition, the threaded portion 17a is passed through the bolt holes formed in one frame 6, the transmission case 7 which is divided into two, and the other frame 6, and the protruding tip is inserted into the spring. A nut 21 is tightened through a washer 20 and held between both nuts 19 and 21 to fix the frame 6 and the split transmission case 7.

つ機体の軽量化を図ることができる。 As explained above, according to the present invention, the support shaft of the tight pulley arm 13 is constituted by the bolt 17 having the threaded portion 7a and the round shaft portion 7b under the neck, so that the support shaft can have an extremely simple structure. is possible,
Further, the boss 15 of the arm 13 was inserted into the round shaft portion 7b, and the nut 19 was screwed into the threaded portion 7a, and the boss 15 was held between the nut and the bolt head 17c, so that the side of the boss 15 such as a collar or flange was inserted. The boss 15 can be easily supported on the support shaft without the need for a member to restrict directional movement, and the nut 19 can be adjusted to prevent the boss 15 from lateral rattling, thereby maintaining smooth rotation of the tight pulley 12. can do. Further, the threaded portion 7a is passed through the frame 6 and the halved transmission case 7 that constitute the machine body, and the nut 21 is tightened, and the halved transmission case 7 is tightened by the nut 21 and the nut 19, and the halved transmission case 7 is tightened. Since the transmission case is fixed to the frame 6, the frame 6 and transmission case 7 can be fixed at the same time as the arm support shaft is installed, reducing the number of parts and assembly man-hours, resulting in a significant cost reduction. In addition, it is possible to reduce the weight of the aircraft.
