[0102]
By the way, a motor 29 is provided in the vicinity of the vertical pipe 13a of the vertical auger 13 for turning it around the vertical axis J. The specific configuration will be described as follows.
[0117]
That is, the motor 29 is installed at a location between the threshing portion 3 and the vertical auger 13 behind the straw tank 12. For this reason, as shown in FIGS. 4-6, while making the pipe-shaped horizontal overhang | projection flame | frame 30 project from the rear-end part of the threshing part 3 to the side outward, it is the same from the upper side part of the milling cylinder 19 back. The pipe-like rearward extending frame 31 is extended. At this time, the inner end of the laterally projecting frame 30 and the front end 31a of the rearwardly projecting frame 31 are coupled by the coupling piece a and the screw stopper b.
[00118]
Further, as shown in FIG. 1, an auger support frame 32 is erected from the outer end of the rear end portion of the chassis frame 7, and the front end portion 30 a of the laterally extending frame 30 is connected to the vicinity of the upper end of the frame 32. As shown in FIG. 5, the notched portion k of the substantially rectangular groove-shaped vertical coupling plate 33 which is fixed to the upper end portion 32a of the auger support frame 32 is bent in an L shape in plan view. One end 34a of the pipe-shaped coupling rod 34 is fixed by welding or the like, and the other end 34b of the coupling rod 34 and the rear end 31b of the rearward extending frame 31 are coupled by a coupling piece a and a screw stopper b.
[0019]
Further, the groove-shaped horizontal coupling plate 35 is fixed along the lateral side portion of the coupling rod 34, and the upper end portion of the groove-shaped vertical coupling plate 36 fixed in the middle of the laterally extending frame 30 is coupled by the screw fastener b. Further, the outer end of the lateral groove-shaped vertical support plate 37 is fixed with the screw fastener b in the middle of the length of the groove-shaped vertical connection plate 33 between the coupling rod 34 and the laterally extending frame 30.
[0020]
On the other hand, as shown in FIGS. 3 and 5, a bearing body 17 is provided for holding the vertical pipe 13a in a freely rotatable manner. The bearing body 17 is formed by connecting two semicircular members 17a and 17b to the vertical pipe 13a with a screw stopper b, and forming a trapezoidal shape in plan view on the outer peripheral surface of the inner semicircular member 17b. A vertically-oriented connecting plate member 38 bent in the direction is fixed by welding or the like.
[00121]
Then, one surface portion 39a of the motor bracket 39 for fixing the leg member 29a fixed to the motor 29 is fixed to the groove-shaped vertical support plate 37, which is the same body as the auger support frame 32, with a screw stopper b, and this one surface portion 39a In addition to fixing the intersecting other surface portion 39b to the connecting plate member 38 which is the same body as the bearing body 17 with the screw stopper b, the vertical plate member 40 is fixed to the left side of the bracket 39 by welding or the like. The portion 40a and the groove-shaped vertical coupling plate 36 are coupled by the screw stopper b.
[0102]
A large-diameter driven gear 41 is fixed at a specific height position of the vertical pipe 13a, and the gear 41 is engaged with a small-diameter driving gear 42 fixed to the output shaft of the motor 29. The auger cover 14 is formed so as to cover the upper surface and the rear surface of the motor 29, and is fixed so as to be detachable via an auger support frame 32 or the like.
[002]
According to such a motor mounting structure, the motor 29 is surrounded by the threshing portion 3 and the vertical auger 13 on the left and right sides, and the front portion is surrounded by the straw tank 12, and forward of the threshing portion 3 and the rear end of the chassis frame 7. Therefore, these structures 3, 7, and 12 function as a strong protective frame against contact of external objects with the motor 29.
[0024]
At this time, since the motor 29 and its mounting member are located behind the dredge tank 12 or further inside the fuselage tank 12 than the inner side surface 12a (see FIG. 4), the swinging opening / closing of the dredge tank 12 around the vertical pipe is performed. There will be no trouble. In addition, since the structures 3, 7, and 12 effectively prevent the motor 29 from being exposed to rainwater, mud, dust, and the like, the auger cover 14 has an outer surface and a rear surface of the vertical auger 13 and an upper surface of the motor 29. A simple bent plate having almost three planes that can be covered is sufficient, and does not protrude significantly from the chassis frame 7.
[0025]
Further, the laterally extending frame 30 and the backwardly extending frame 31 are fixed to a tough portion of the threshing portion 3, and form a box frame structure together with the threshing portion 3, the auger support frame 32, the chassis frame 7, and the like. The bearing body 17 is fixed very effectively. Further, since the auger support frame 32 and the bearing body 17 are coupled via the two intersecting surfaces 39a and 39b of the motor bracket 39, the coupling structure is formed in a three-dimensional shape and each coupling point is in surface contact, and these couplings are made. Strength will be strong.
[0102]
Under such a structure, when the motor 29 is rotated in an arbitrary direction, the rotation is decelerated by a reduction gear mechanism built in the motor 29 to rotate the driving gear 42, and this rotation is transmitted via the driven gear 41. It is transmitted to the vertical pipe 13a. Thereby, the vertical pipe 13a idles in the tank receiver 18 while being supported by the lower conveyor case 15a and the bearing body 17, and the upper auger 16 is swung in the same body.
[0027]
At this time, the tank receiver 18 and the lower conveyor case 15a are subjected to rotational force due to friction generated by the turning of the vertical pipe 13a. However, the dredge tank 12 is locked by a locking means (not shown). There is no inadvertent opening and closing displacement.
[0028]
Further, when the motor 29 turns the vertical pipe 13a, the mounting force of the motor 29 is microscopically distorted by the reaction force, but this distortion is only transmitted to the motor 29 via the motor bracket 39. Therefore, the influence on the motor 29 is reduced.
[0029]
【The invention's effect】
According to the present invention described above, the bearing body is firmly supported in addition to the vertical auger turning motor, so that the vertical pipe can be smoothly turned by the vertical auger turning motor, and the vertical pipe is further strongly supported. Will be.
[0030]
According to the second aspect of the present invention, since the motor bracket is three-dimensionally supported and effectively fixed to the auger support frame reinforced by the laterally extending frame and the backwardly extending frame and the bearing body, The motor or the like can be firmly supported without exerting a large external force upon the operation of the auger turning motor.
