Therefore, in the transmission gearbox 26 to which the rotation from the engine 20 is input, the rotation is branched and transmitted to each of the three parts of the handling cylinder 7 and the like, the swing sorting shelf 9 and the like, and the front grain supply and transfer device 16 and the like The transmission mechanism can be configured at a low cost and at a low cost.
The transmission gear box 26 is separately provided with an optional external device output shaft 61A, and an external device such as an air conditioner or a hydraulic pump is driven from the external device output shaft 61A.
That is, since the constant rotation is always transmitted to the external device, it is convenient to output the transmission gear box 26 to the external device from the transmission gear box 26 to which the constant rotation from the engine 20 is transmitted. Thus, the transmission gear box 26 can be used in common, and the entire transmission path can be made compact by shortening the transmission path.

Therefore, the body frame 1 is configured by combining a plurality of horizontal frames 62 in the left-right direction and a plurality of vertical frames 63 in the front-rear direction. The transmission gearbox 26 is mounted on the beam (FIGS. 6 and 7).
The tension of the belt 24 with the engine output pulley 22 of the engine 20 is greatly applied to the intermediate input pulley 23 of the transmission gear box 26, but the intermediate input pulley 23 and the engine output pulley 22 are separated by a vertical frame 63 that is long in the overall length of the machine body. The support pitch of the transmission gear box 26 is improved by increasing the mounting pitch in the front-rear direction to provide a strong support structure.
Thus, the threshing output pulley 30 is provided on the front side of the transmission gear box 26 (FIG. 7), and the transmission gear box is located behind the belt 34 wound between the threshing output pulley 30 and the barrel input pulley 31. 26 is located.
Therefore, since the transmission gear box 26 is disposed behind the belt 34, the space between the cutting suspension base (not shown) of the cutting unit 4 and the transmission gear box 26 can be widened, although illustration is omitted. The hot air discharge from 20 is improved, and the heat balance is effective.
Moreover, it becomes easy to fix and support the transmission gear box 26 to the threshing device 3, and a rational configuration is obtained.

For example, when the transmission gear box 26 is attached to the threshing frame 65 provided below the handling cylinder 7 of the threshing device 3 by the attachment member 66 (FIG. 7), the transmission gear box 26 can be attached integrally with the threshing device 3 during assembly. Thus, since the driving test can be performed before the threshing device 3 is mounted on the body frame 1, it becomes easy to find a defect, and the correction man-hours after mounting on the body frame 1 are not required, and the entire operation can be rationalized.
That is, since the distance between the threshing device 3 and the transmission gear box 26 does not change, for example, the inter-axis distance between the threshing output pulley 30 and the handling cylinder input pulley 31 is not changed, and there is little deviation.
Therefore, a tension clutch pulley 67 is brought into contact with and separated from the belt 34, and the tension clutch pulley 67 is provided at the tip of the tension arm 68. The base of the tension arm 68 is attached to the transmission gear box 26 by a shaft 69 (FIG. 9).
In this case, the shaft 69 supports both the base portion and the tip protruding from the tension arm 68 in a so-called both-end supported state by the support portion 70 of the transmission gear box 26.
When the tension clutch pulley 67 is engaged, the handling cylinder 7 has a large starting torque, and a large shocking force may be applied to the shaft 69. Therefore, it is possible to disperse the load, prevent breakage, and reduce the weight.

Further, by attaching the tension clutch pulley 67 of the belt 34 to the transmission gear box 26, the transmission gear box 26 can also be used as an attachment member, and the arrangement accuracy of the threshing output pulley 30, the barrel input pulley 31, and the tension clutch pulley 67 is also improved. And the occurrence of problems such as the belt 34 coming off is prevented.
Thus, the transmission gear box 26 is provided with a lower cylindrical portion 72 projecting to the left (engine 20 side) below the main body case 71 in a front view, and the intermediate input shaft 25 is mounted on the lower cylindrical portion 72 ( FIG. 10). Further, an upper cylindrical portion 73 protruding rightward is provided above the main body case 71, the sorting output shaft 40 is mounted on the upper cylindrical portion 73, and the sorting output pulley 41 is fixed to the sorting output shaft 40. . In addition, a bevel gear 74 that rotates by rotation from the threshing output shaft 27 is mounted at the upper and lower intermediate positions of the main body case 71, and the bevel gear 74 transmits the rotation to the threshing output pulley 30.
Therefore, the transmission gear box 26 is formed in a substantially “Z” shape when viewed from the front (FIG. 10), and has a shape that balances the tension of the belt and a shape that is long in the vertical direction. The overall length of the combine can be shortened, resulting in a rational configuration.

Further, a battery 75 is provided below the upper cylindrical portion 73 (FIGS. 5 and 10). The battery 75 is arranged on the front left side of the threshing device 3, and maintenance such as attachment / detachment / replacement / charging of the battery 75 can be easily performed. In addition, since the upper cylindrical portion 73 is provided above the battery 75 and the sorting output pulley 41 is mounted on the upper cylindrical portion 73, the sorting output pulley 41 can be arranged using the space effectively.
Thus, the transmission gear box 26 has a lower cylindrical portion 72 positioned below the main body case 71 in a side view, and an upper cylindrical portion 73 provided above the main body case 71, and the main body case 71, the lower cylindrical portion 72, The upper cylindrical portion 73 is formed in a vertically long shape with substantially the same width, and the sorting output pulley 41 mounted on the upper cylindrical portion 73 is used to add the cereal to the cereal supply port 79 formed on the front plate 78 of the threshing device 3. It arrange | positions in front of the swing sorting shelf 9 under the entrance funnel (funnel) 76 (FIG. 3) to guide.
In addition, since the transmission gear box 26 is configured to be vertically long, a space between the cutting suspension base (not shown) of the cutting unit 4 and the transmission gear box 26 can be widened, and the hot air discharge from the engine 20 is improved. , Effective in heat balance.

The intermediate input pulley 23 of the lower cylindrical portion 72 of the transmission gear box 26 is positioned below the starting end portion of the swing sorting shelf 9, so that it is between the engine output shaft 21 of the engine 20 and the intermediate input pulley 23 of the transmission gear box 26. The distance can be increased, and troubles such as attachment and detachment of the belt 34 can be prevented.
In this case, when the axial center of the lower cylindrical portion 72 is positioned behind the front plate 78 of the threshing device 3 (FIGS. 7 and 8), an intermediate input pulley between the engine output shaft 21 of the engine 20 and the transmission gear box 26. 23 can be increased, and the durability of the bearings of the engine output shaft 21 and the intermediate input pulley 23 is improved.
Thus, since the threshing output pulley 30 is mounted on the upper and lower and left and right intermediate positions of the main body case 71 of the transmission gear box 26, the transmission gear box 26 also serves as the transmission case of the threshing output pulley 30, It is a rational structure.
That is, the threshing output pulley 30 can be arranged below the handling cylinder input pulley 31 of the handling cylinder 7, and the distance between the axes of the threshing output pulley 30 and the handling cylinder input pulley 31 can be shortened.

Further, when the threshing output pulley 30 is arranged on the left side of the front view from the center of the handling cylinder 7 (FIG. 10), the entrance funnel 76 can be avoided and the belt 34 can be made into a reasonable line, thereby improving durability. , Reduce costs.
In addition, since the line of the belt 34 is avoided by avoiding the entrance funnel 76, an extra counter pulley or the like is unnecessary, and the configuration can be simplified.
Therefore, the transmission gear box 26 of the embodiment is provided with a compressor 80 of an air conditioner (not shown) (FIG. 11), and the transmission gear box 26 is also used as a transmission case of the compressor 80. The compressor 80 is located between the intermediate input pulley 23 and the battery 75 when viewed from the front, and below the threshing output pulley 30.
Therefore, a transmission case dedicated to the compressor 80 is not required, the number of parts is reduced, both cost and weight are reduced, and space can be used effectively.
