You.

The power transmission configuration of the mowing unit 5 is such that the side vertical transmission pipe 33 is provided on the side of the lower horizontal transmission pipe 18, and the side horizontal transmission pipe 33 is provided in the upper and lower middle part of the side vertical transmission pipe 33. 37, the case of the left stock transfer device 10 is mounted on the lower part of the side downward mounting pipe 41 extending downward from the side horizontal transmission pipe 37, and on the right side of the lower horizontal transmission pipe 18 The upper part of the upward mounting pipe 118 is mounted, and the case of the right stock side transport device 10 is fixed to the upper part of the upward mounting pipe 118.

In this case, the stock transfer device 10 and the tip-side transfer device 11 located outside the traveling paths of the left and right outer stocks.
Does not cause the problem of stock catching, but the stock transfer device 10a and the tip side transfer device 11a located inside the traveling path of the left and right outer stocks have the transmission pipe hooking of the stock being transferred. Problem may occur. However, the above-described configuration includes the stock-side transport device 10 and the tip-side transport device 1.
1, the stock-side transport device 10a and the tip-side transport device 11a, which are located inside the traveling path of the left and right outer strains, are respectively provided with the upper horizontal transmission in the left and right direction provided above the side vertical transmission pipe 33. A downward mounting pipe 80 hanging down from the pipe 60 and a downward mounting pipe 85 extending further below the downward mounting pipe 80;
Since the crank-type transmission pipe 87 is attached to the lower part of the downward transmission pipe 105, the stock-side transfer device 10a and the tip-side transfer device 11a have no protrusions below the case as in the conventional case. In addition, since there is nothing protruding upward from the lower horizontal transmission pipe 18, not only there is no adhesion of mud straw debris and the like, but also the grain stalk is smoothly transported.

Since the lower horizontal transmission pipe 18 is not provided with the transmission pipe of the stock-side transfer device 10a,
Even if the left and right width of the lower horizontal transmission pipe 18 is shortened and the transmission mechanism of the cutting blade 9 is provided at the end thereof, the transmission mechanism of the cutting blade 9 can be accommodated within the left and right width of the cutting blade 9, It works well without affecting uncut kernels. Conventionally,
The upper part of the side vertical transmission pipe 33 is directly connected to the upper horizontal transmission pipe 6.
However, in the present embodiment, a box 51 is provided at the upper part of the side vertical transmission pipe 33, and a side part is provided at the lower rear side of the box 51. The vertical transmission pipe 33 is fixed, and the upper part of the downward transmission pipe 52 is fixed to the lower front side of the box 51.
Since the upper horizontal transmission pipe 60 is fixed to the upper part of the box, the area of the box 51 becomes large, and the box 51 of the mounting portion becomes a part of the frame, thereby improving the overall strength and the strength of the mounting portion. .

Thus, the two raising devices 7 of which the non-operating sides are opposed to each other are the two inverted T-type transmission pipes 64 attached to the upper horizontal transmission pipe 60 by one vertical cylindrical portion 65. Further, since the ears of the cereal culm conveyed through the conveying passages on the left and right sides of the pulling device 7 are smoothly conveyed rearward without contacting the vertical cylindrical portion 65 because they are attached to the left and right sides of the cylindrical portion 70. . Further, since the two raising devices 7 are directly mounted by the inverted T-type transmission pipe 64, the mounting strength can be improved and the positioning can be easily performed. That is, the lugs of the right and left raising devices 7 alternately enter the case. However, since the mounting positions are accurate, it is possible to prevent the two lugs from contacting each other and being damaged.

Further, since the raising device 7 located on the inner side of the traveling path of the right outer plant is attached to the crank type transmission pipe 87, the right culm is turned over and the stock transfer system 13 and Even if there is a tendency to be transferred to the tip transfer device 14, the crank-type transmission pipe 8
Since the vertical cylindrical portion 88 of 7 is separated, there is no conveyance resistance.

Since the horizontal cylindrical portion 92 of the crank-type transmission pipe 87 of this embodiment shares the right side of the bifurcated cylindrical portion 70 of the inverted T-type transmission pipe 64, the cost is reduced. . After the mowing operation is completed, the mowing unit 5 is removed from the machine side to perform maintenance, etc.
Since the mowing section input pulley 22 is mounted on the gear case 20 provided on the side of the horizontal cylinder 19 provided on the side opposite to the control section 4, the transmission mechanism can be easily removed.

As described above, conventionally known ones are formed, for example, as shown in FIG. 5 in the form of a five-row type that cuts five rows of stocks, and the five rows of stocks advance as indicated by arrows. When gathering at the takeover part of the location, the stock feeder and the head-side transporter located outside the path of the left and right outer strains do not cause the problem of stock trapping, but the path of the left and right outer stocks There is a problem that the stock is hooked on the transmission shaft located inside.

However, with the above configuration, the stock transfer device 10a and the tip-side transfer device 11a located inside the transfer passage are provided with the transmission shaft 8 hanging down from above.
Since the number is 1,106, the lower part becomes a wide space, and even if straw waste is entangled, it falls and the grain stem is smoothly transported through the transport path.
