A stock-side transfer device for nipping and transferring the stock side of the cereal stem and a head-side transfer device for transferring the head side are provided.

[0003] The tip-side transport device is generally driven by the upper end of a transmission shaft provided upward from below the tip-side transport device. In addition, 56
In the microfilm of No.-107247, there are a plurality of weeds for weeding the cereals, a plurality of raising devices for raising the cereals culled by the weeds, and a mowing for cutting the cereals caused by the raising devices. In a cutting device provided with a blade, a root-side transport device for nipping and transporting the root side of a grain stem cut by the cutting blade, and a tip-side transport device for transporting the tip side, the plurality of raising devices are interlocked. An upper horizontal transmission shaft driven below is disposed below the upper end of the raising device, and the plurality of raising devices are directly driven from the upper horizontal transmission shaft, while the tip-side transport device is moved downward from the upper horizontal transmission shaft. A combine harvester that is configured to be driven via a provided vertical transmission shaft and that supports the vertical transmission shaft on the upper rear side of the raising device is described.

[0004] The microfilm of Japanese Utility Model Application Laid-open No. 63-86727 includes a plurality of weeds for weeding cereal stems, a plurality of raising devices for elevating the cereals culled by the weeds,
A cutting blade for cutting the culm raised by the raising device and a stock-side transfer device for nipping and conveying the stock side of the cereal stem cut by the cutting blade; An upper horizontal transmission shaft driven above and arranged above the upper end of the raising device, wherein the plurality of raising devices are configured to be driven via a vertical transmission shaft provided downward from the upper horizontal transmission shaft, and A combine harvester is described in which a transmission shaft is supported between an upper horizontal transmission shaft and an upper rear side of a raising device and is provided in a steeply inclined posture standing upright from the raising device.

[0005]

In the prior art described above, for example, referring to FIG. 5, in the case of a configuration in which five rows of cereals are cut, the cut culms are represented by arrows as shown by arrows. The sheet is conveyed and joins the transfer section to the rear transfer apparatus. At this time, since the tip-side transport device is configured to be driven by the upper end of the transmission shaft provided upward from below the tip-side transport device, the root side of the transported grain culm interferes with the transmission shaft, There is a problem that straw waste is likely to accumulate around the transmission shaft, hindering the transport of grain stalks, and reducing the efficiency of cutting work.

Further, in the configuration described in the microfilm of Japanese Utility Model Application Laid-Open No. Sho 56-107247, a plurality of raising devices are directly driven by an upper horizontal transmission shaft. Since it is arranged below the upper end of the grain, the raised tip of the grain stem interferes with the upper horizontal power transmission shaft, and there is a problem that the grain is grained and the grain posture is easily disturbed.

[0007] Further, in the configuration described in the microfilm of Japanese Utility Model Application Laid-Open No. 63-86727, since the head-side conveying device for conveying the head side of the harvested grain culm is not provided at an appropriate height, the grain culm posture is not provided.

It has a configuration in which it can be rotated up and down, and there is no suggestion of a technical idea that such a transport device can be driven in conjunction with the upper horizontal transmission shaft that drives the raising device. Therefore, the above-mentioned actual disclosure 56-1072
Technology disclosed in No. 47 microfilm and Shokai 6
Even if an attempt is made to combine the technique disclosed in the microfilm of JP-A-3-86727, the upper horizontal transmission shaft is arranged above the upper end of the raising device, and both the raising device and the tip-side transport device are connected to the upper horizontal portion. It cannot be configured to be driven via a vertical transmission shaft provided downward from the transmission shaft.
Therefore, it is not possible to arrange the upper lateral transmission shaft for driving the spike-side conveying device at an appropriate height while arranging the spike-side conveying device at an appropriate height. The problem remains that the harvested culm cannot be transported smoothly. In addition, the raising device and the tip-side transport device cannot be driven by a series of vertical transmission shafts, and the problem remains that the transmission configurations of the raising device and the tip-side transport device cannot be simplified and provided at low cost. .

Also, since the ears of the cereal culm conveyed through the conveying passages on the left and right sides of the raising device 7 are smoothly conveyed rearward without contacting the vertical cylinder 65 because they are attached to the left and right sides of the cylinder 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 grain 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.

The horizontal tubular portion 92 of the crank-type transmission pipe 87 of this embodiment shares the right side of the bifurcated tubular portion 70 of the inverted T-type transmission pipe 64, thereby reducing costs. . 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, in the case of the conventionally known one, for example, as shown in FIG. 5, when a five-row type is formed by cutting five rows of stocks, 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.
