The ring gear (42) has inner teeth (42a) that mesh with the planetary gears (41), and the carrier shaft on the same axis as the sun gear shaft (43). (44) is rotatably supported.

  Furthermore, the traveling hydraulic continuously variable transmission mechanism (29) controls forward / reverse rotation of the transmission motor (28) and the number of rotations by adjusting the angle of the rotary swash plate of the transmission pump (27). The rotational output of the transmission motor (28) is fixed to the sun gear shaft (43) from the transmission gear (46) of the output shaft (35) via the gears (47) (48) (49) and the auxiliary transmission mechanism (36).

I will change the running speed and turn the aircraft It is configured to.

  By the way, as shown in FIG. 15, the cab (16) is divided into a central movable table (16A) and a fixed frame base (16B) around the central movable table (16A). 13) and an interlocking mechanism (73) on the lower surface, and the front end side of the movable base (16A) is supported on the fixed frame base (16B) via the pivot point (132) so as to be movable up and down.

  Further, during the forward operation of tilting the main transmission lever (72) forward, the turning rod (94) is pulled by the left turning operation of the handle (15), and the swing link (82) is moved to the left angle (β2) side. By tilting the output portion (82a) of the swing link (82) closer to the turning arm (87) side, and the joint portion (91a) with the turning joint shaft (91) about the third pivot (84). The swing arm (87) is swung in a direction away from the swing link (82) side (counterclockwise in FIG. 7), the control lever (77) is rotated upward, and the steering motor (31 ) In the reverse direction. That is, it is configured to turn the aircraft forward (turn the speed of the traveling crawler (2) large on the right side and small on the left side).

  Further, the rocking link (83) is tilted toward the angle (α2) behind the neutral position by the backward operation of tilting the main transmission lever (72) backward, and the turning rod (94) is moved by the right rotation operation of the handle (15). By pushing rightward and tilting the swing link (82) to the right angle (β1) side, the output portion (82a) of the swing link (82) is brought closer to the swing arm (87) side, and the third pivot ( 84), the joint arm (91a) with the pivot joint shaft (91) is pivoted in the direction away from the swing link (82) (counterclockwise in FIG. 7), and the control is performed. The lever (77) is rotated upward, and the steering motor (31) is reversely rotated. In other words, the vehicle is configured to turn backward (turn the crawler (2) at a higher speed on the left side and lower on the right side).

  In addition, when the main transmission lever (72) is operated backward, the swing link (82) is tilted to the left angle (β2) side by the left turn operation of the handle (19), thereby the swing link (82). The output portion (82a) is moved away from the swivel arm (87), and the swivel link (82) is swung with the swivel link (82) with the swivel joint shaft (91) centered on the third pivot (84). 82) is rotated in a direction approaching the side (clockwise in FIG. 7), the control lever (77) is rotated downward, and the steering motor (31) is rotated forward. That is, the aircraft is configured to turn backward (turn the crawler (2) at a higher speed on the right side and lower on the left side).

  As shown in FIGS. 17, 20, and 21, a radiator (158) is disposed in the left opening of the engine room (11) facing the cooling fan (157) of the engine (12), and the radiator (158). The outer cover is covered with a radiator cover (159). The radiator cover (159) has an oil cooler (160) attached to the inner side surface, and covers the right outer side with the rear fulcrum shaft (161) at the rear end of the cover (159) as the center. (159) is provided to be freely opened.

  The fuel tank (162) of the engine (12) is disposed outside the right threshing side plate (4b) below the engine (12), and the grain tank (8) in front of the vertical discharge auger (149). A hydraulic oil tank (163) for supplying hydraulic oil to the continuously variable transmission mechanism (29) (32) is disposed on the right outer surface of the threshing section (4), grain tank (8), engine ( 12) These tanks (162) and (163) are configured so as to be simply arranged without adversely affecting them. In addition, (164) is an air cleaner and (165) is an exhaust pipe.

  Further, the rear threshing cover (166) behind the engine frame (11) is provided to be freely opened rearward around the left fulcrum shaft (167) on the left side, so that maintenance and inspection of the engine (12) can be easily performed. It is configured to make it.

  Furthermore, a rear guard frame (168) is provided behind the threshing part (4) rear side transmission case (26), and the intermediate part of the gate-shaped guard frame (168) is lowered rearward of the mission case (26). In addition to facing the slope, the left and right base ends of the guard frame (168) are fixed to the left and right side plates (4a) and (4b), so that there are obstacles in the field when the aircraft is moving backwards. The dynamic sorter (7) and the third exit (140) are configured to be protected from obstacles. Then, the shifting and turning wires (74) and (75) are connected to the swinging arms (126) and (127) of the outer shaft (124) and the inner shaft (125). ) Easy to enable from outside, and to enable connecting / disconnecting operation and adjusting operation of each rod (130) (131) and control lever (76) (77) from the rear side of the machine. It is configured as follows.

  On the other hand, as shown in FIGS. 17 and 21, the battery (169), the hydraulic lifting cylinder (19) and the horizontal control are provided on the right side of the feeder house (21) inside the step (16a) of the cab (16). A hydraulic device (170) such as a cylinder switching operation valve is centrally arranged, and a battery (169) and a hydraulic device (in the surplus space (171) formed between the right side of the feeder house (21) and the lower side of the step (16a) ( 170) is compactly and satisfactorily stored and held, and maintenance and inspection are facilitated, so that these performances can be stably maintained.

  As is apparent from the above-described embodiments, the present invention provides an ordinary combine that installs a cutting part (18) that can be moved up and down via a feeder house (21) in front of a threshing part (4). Since various hydraulic devices (170) for raising and lowering control are centrally arranged at the right side position of the feeder house (21), various hydraulic devices (170) are provided in the right surplus space (171) of the feeder house (21). Can be incorporated in a compact manner, and the efficiency of these maintenance and inspection operations can be improved, so that the performance of these hydraulic devices (170) can be maintained stably.

  Furthermore, since the threshing part (4) is provided with left and right outer threshing covers (151) (153) on the upper fulcrum shaft (155) (156) so as to be freely opened upward, the left and right threshing covers (151 ) (153) can be easily opened and the threshing performance can be stably maintained without troublesomeness.

  Further, the engine (12) is disposed on the rear upper side of the threshing section (4), and the grain in the tank (8) is taken out to the right outside of the grain tank (8) in front of the engine (12). Since the discharge auger (149) is disposed, the grain tank (8) and the engine unit are integrated in the rear upper part of the threshing unit (4), and the engine (12) is integrated. And a vertical installation auger (149) that does not adversely affect the threshing section (4) can be made compact.

  Furthermore, since the fuel tank (162) of the engine (12) is disposed at the lower right side of the engine (12) on the right outside of the threshing section (4), the threshing is performed even in the large-capacity fuel tank (162). It can be made compactly installed without adversely affecting the part (4), the grain tank (8) and the engine (12) or taking up space.

  In addition, since the rear guard frame (168) is disposed on the rear side of the threshing part (4) and behind the mission case (26), there is an obstacle in the field scene in the backward direction when the aircraft is moving backward. Even in this case, the guard frame (168) avoids the inconvenience that the mission case (26) or the like directly touches the obstacle, and damages the third exit (140) of the threshing part (4) or the mission case (26). This can be prevented.
