Stick with etc.

The leg member 29 fixed to the motor 29
One side 3 of motor bracket 39 for fixing a
9a is a grooved vertical support plate 3 which is the same as the auger support frame 32.
7 with a screw fastener b, and the other surface 39b crossing the one surface 39a is connected to the connecting plate member 3
8, a vertical plate member 40 is fixed to the left side of the bracket 39 by welding or the like, and the rear portion 40a of the member 40 and the grooved vertical coupling plate 36 are fixed to the bracket 39 with the screw fastener b. Join.

According to such a motor mounting structure, the motor 29 is surrounded by the threshing unit 3 and the vertical auger 13 on the left and right sides, the paddy tank 12 on the front side, and from the threshing unit 3 and the rear end of the chassis frame 7. Are also located forward and fit completely inside the fuselage, and therefore these structures 3, 7, 12
Functions as a tough protective frame against external objects coming into contact with the motor 29.

At this time, the motor 29 and its mounting member are located behind the paddy tank 12 or on the inner surface 12 of the paddy tank 12.
a (refer to FIG. 4), which does not hinder opening and closing of the paddy tank 12 around the vertical pipe. In addition, the structures 3, 7, and 12 effectively prevent rainwater, mud, dust, and the like from being applied to the motor 29. Therefore, the auger cover 14 covers the outer surface and the rear surface of the vertical auger 13 and the upper surface of the motor 29. A simple bent plate consisting of almost three planes that can be covered is sufficient, and does not protrude greatly from the chassis frame 7.

The horizontal overhanging frame 30 and the rearward overhanging frame 31 are fixed to a strong portion of the threshing unit 3,
Moreover, a box frame structure is formed together with the threshing unit 3, the auger support frame 32, the chassis frame 7, and the like, and the mounting part of the motor 29 and the bearing 17 are fixed very effectively. Further, the crossed two-sided portion 39 of the motor bracket 39
auger support frame 32 and bearing body 1 through a and 39b
The bonding of 7 makes the bonding structure three-dimensional and makes each bonding part a surface contact, thereby increasing the bonding strength.

Under such a structure, when the motor 29 is rotated in an arbitrary direction, the rotation is reduced by a reduction gear mechanism built in the motor 29 to rotate the driving gear 42, and this rotation is performed by the driven gear 41. Through the vertical pipe 13a
Is transmitted to As a result, the vertical pipe 13a idles in the tank receiver 18 while being supported by the lower conveyor case 15a and the bearing member 17, and the upper auger 16
To turn.

At this time, a rotational force due to the friction generated by the turning of the vertical pipe 13a acts on the tank receiver 18 and the lower conveyor case 15a, but the paddy tank 12 is locked and unlocked by locking means (not shown). Therefore, there is no inadvertent opening and closing displacement.

When the motor 29 rotates the vertical pipe 13a, the reaction force causes the mounting member of the motor 29 to be microscopically distorted.
Is transmitted only to the motor 29 via the.
