ンバインも既に知られている。(b) Prior Art Conventionally, grain culms harvested by a reaping device are transported later by a vertical conveyance device, the starting end of the feed chain of the threshing device is made to hang diagonally forward, and this hanging portion overlaps with the conveyance terminal end of the vertical conveyance device. It is already known from Japanese Utility Model Publication No. 17142/1983 that the stem part of the vertically conveyed grain culm is transferred to the hanging part of the feed chain. In conjunction with this, the pre-processing device consisting of the reaping device, vertical conveyance device, etc. is stopped, and the threshing device continues to be driven by the engine separately from the traveling device, etc. to drive the handling cylinder, sorting device, etc. Combine harvesters are already known.

題点を解決した。(d) Means for solving the problem The present invention provides a grain culm lifting system in which the feed chain of the threshing device is used as a driving source between the end of the vertical conveying device and the threshing device and the grain culm is lifted in a horizontal position. A device is provided, and a clutch is interposed in the drive part of the grain culm lifting device to intermittent the power from the feed chain, and this clutch is interlocked with the clutch of the preprocessing device to stop the vertical conveyance device of the processing device. The grain culm lifting device is also stopped, thereby preventing the grain culm lifting device from pulling out the grain culm held obliquely at the end of the vertical conveying device, thereby solving the above-mentioned problem. Settled.

(ホ) 作用 刈取脱穀作業中、縦搬送装置は刈取装置が刈取

る。 Further, the driving sprocket 37 of the stock head lifting body 17 and the driving sprocket 38 of the ear side lifting body 18
As shown in FIG. 5, the driven sprocket 40 of the feed chain 1a is mounted on a shaft 41 which supports the driven sprocket 40, and the clutch 43 in the clutch case 42 is operated by a shifter 44 to engage the clutch carved into the side surface of the driven sprocket 40. The shifter 44 is connected to and disengaged from the claw, and the shifter 44 is connected to the traveling clutch pedal 45 by a wire 46.
Since the clutch pedal 45 for traveling and pretreatment is depressed during work, the grain culm consisting of the clutch for traveling and pretreatment, the stock head lifting body 17 and the ear side lifting body 18 is moved. Lifting device clutch 43
Since they are cut off substantially synchronously, the pre-processing device consisting of the reaping device and the vertical conveyance device 16 etc. are stopped substantially at the same time.

3 is driven by a pulley 84 in front of the submission 57, and its output pulley 85 is interlocked and connected to the pulley 87 of the intermediate shaft 86 by a belt 88 with a clutch pulley, and the sprocket 89 of the intermediate shaft 86 and the rear horizontal shaft case 60 are connected to each other. A sprocket 91 attached to the horizontal shaft 90 is interlocked with a chain 91a, and the bearing 86a of the intermediate shaft 86 has a rear bending arm 92 whose rear part is rotatably fitted into the bearing tube 85a of the output pulley 85. The rear surface is supported by a semicircular receiver provided at the front end of the front bending arm 9.
The upper part of the frame 3 is fixed to the bearing 86a, and the lower part is loosely fitted to the rear horizontal shaft case 60. Therefore, when the preprocessing frame is raised and lowered in a substantially constant posture by the hydraulic cylinder 56, the transmission 82 is connected to the machine base 3. In contrast, the rear horizontal shaft case 60 is a transmission case 73.
The front refraction arm 93 and the rear refraction arm 9 move up and down while changing the relative distance integrally with the
The threshing device 1 is separately driven by the engine E, and the intermediate shaft 86 of the threshing device 1 is bent and extended using the intermediate shaft 86 of the threshing device 1 as a bending point, so that the distance between the shafts does not change and smooth transmission can be performed.
