This is a mounting transmission tube to be mounted. Next, the operation will be described. (Normal work) The rotation of the engine 34 is transmitted to the HST pump 33,
The ST pump 33 speed-changes by continuously increasing or decreasing the oil supply amount to the HST motor 32 to change the transmission case 31
The rotation is transmitted to the axle 35 of the vehicle to make the vehicle travel. On the other hand,
The rotation transmitted to the transmission case 31 via the HST motor 32 is transmitted to the input shaft 37 of the reaping section transmission 30 via the output shaft 36, and the rotation of the input shaft 37 is normally performed by the normally engaged clutch 42. The rotation is transmitted to the standard gear 41, the rotation of the standard gear 41 is transmitted to the transmission input gear 47 via the intermediate large gear 45, and the rotation of the transmission input gear 47 loosely fitted to the switching clutch shaft 46. Is transmitted to the switching clutch shaft 46 by the transmission-side input clutch 48, and the rotation of the switching clutch shaft 46 is transmitted to the output shaft 53 via the gear 55 fixed to the switching clutch shaft 46 and the gear 54 fixed to the output shaft 53. Is transmitted from the standard clutch 42 to the output shaft 53 through the standard transmission path A, and is output from the reaper output pulley 56 to the reaper 4. The reaping unit 4 weeds the plant with a fixed weeding body 5, raises it with a rag rotation type raising device 6, and crushes the culm raised by the rug rotation type raising device 6 with a rag rotation type weeding device. 10 and weed by the scraping device 19 to remove the cutting blade 2
The root of the culm cut and harvested in 1 is conveyed by the cereal culm conveying device 22 on the stock side, and the tip side is conveyed by the cereal culm conveying device 23 on the tip side. Then, the grain is transferred to the grain culm supply / transportation device 27 that supplies the threshing room of the threshing device 3 by the tip-side grain culm transfer / transport device 25, and threshing is performed. in this case,
Since the rotation of the engine 34 is shifted by the HST transmission mechanism 38 and output from the transmission case 31 to the axle 35 and the output shaft 36, the traveling speed of the traveling device 2 and the lug rotation type raising device 6 And the working speed of the cutting section 4 such as the raising of the seed-side grain culm transport device 22 and the transport of the tip-side grain culm transport device 23 can be synchronized, and a smooth operation can be performed. In addition, rotation of the cutting output pulley 56 may be transmitted to the stock side side grain culm transfer device 24, the ear side transfer device 25, the grain culm supply transfer device 27, etc.
The transmission destination is arbitrary. (Lodging Grain Stalk Harvesting Operation) In the lodging grain culm cutting operation, if the raising speed of the grain culm of the raising lug 8 of the lug rotating type raising device 6 of the cutting unit 4 is slow, the lodging grain culm is sufficiently raised. Since the root is cut without cutting, the working speed of the reaper 4 can be made smoother if it is relatively higher than the running speed. Therefore, when the lodging clutch 40 of the mowing unit transmission 30 is engaged, the input shaft 3
7 is transmitted to the lowering gear 39 via the lowering clutch 40 on the lowering transmission path B, and is combined with the lowering gear 39 and the intermediate small gear 44 to transmit the standard transmission path A.
The speed change intermediate shaft 43 rotates faster than the speed change intermediate shaft 4.
The rotation of No. 3 is transmitted to the transmission-side input gear 47 via the intermediate large gear 45 and is output to the reaper 4 from the reaper output pulley 56 in the same manner as described above. Therefore, the reaper 4
The transport speed of not only the rag rotation type raising device 6 but also the scraping device scraping device 19, the stock side grain culm conveying device 22, the tip side grain culm conveying device 23, etc. is increased, and Mowings smoothly. In the above case, the moving (upward) speed of the raising rug 8 of the rag rotation type raising device 6 is increased, so that the grain culm is raised. The pair of upper and lower gears (not shown) causes the raising lug 8 to rotate in a direction intersecting with the body traveling direction to raise the grain culm. The grass may not be enough, and the grain culm may be conveyed with the tip side tangled, but the left and right sides of the mowing part 4 and the raising lug 8 are folded and moved downward in the case 7 by a lug rotating type. Since the lug rotation type weeding device 10 is provided on the non-operating side of the raising device 6, the weeding lug 15 is formed by the gears 12 and 13 that rotate the horizontal axis of the lug rotation type weeding device 10 in the horizontal direction.
Rotates parallel to the advancing direction of the aircraft, so that the culms tangled in the vertical direction are also vegetated and raised. The cutting section frame 57 of the cutting section 4 is
The upper frame 60 is provided with a transmission shaft 67, and the transmission shaft 67
, The transmission engaging member 76 is freely slidable and the transmission gear 77 is provided in a loosely fitted state to form the auxiliary weeding pulling-in / off clutch 75.
When the lodging clutch 40 is turned on, the motor 7 is automatically turned on.
9 is operated to turn on the auxiliary weeding start-off clutch 75 by the shifter 78. Therefore, operability is improved. In this case, if the fall clutch 40 of the mowing unit transmission 30 is configured to be turned on and off by a switch attached to the main transmission lever of the HST transmission mechanism 38 (main transmission), the operation is further facilitated. In the rotation transmission path from the cutting unit input pulley 64 to the lug rotation type raising device 6, a lug raising load detection device 82 for detecting the rotation load of the raising lug 8 is provided. The load detecting device 82 accurately detects the load of raising the lug rotation type raising device 6 and sets the mode to the falling mode.
When the load decreases, the clutch 40 for auxiliary weeding and the clutch 75 for turning off and on the auxiliary weeding can be turned off and the clutch 42 for standard can be turned on. In addition to the improvement, the load applied to the raising lug 8 of the lug rotating type raising device 6 can be accurately detected, so that the correspondence to the falling mode is made accurate. However, if the working speed of the reaper 4 becomes faster than a predetermined speed, it may have an adverse effect. When the rotation of the output shaft 53 reaches the predetermined speed, the engine-side input clutch 50 is automatically turned on. And the constant rotation of the engine 34 is transmitted from the switching clutch shaft 46 to the output shaft 53 via the gear 55 and the gear 54 through the constant speed transmission path C from the engine 34 to the output shaft 53. Therefore, the working speed of the mowing unit 4 is kept constant. In addition,
The structure of the mowing unit transmission 30 and the auxiliary weeding pulling in / out clutch 75, the clutches 40, 42, 48,
The combination of turning on / off 50, the relationship with the auxiliary transmission in the mission case 31, the control order, and the like are arbitrary. According to the present invention, threshing provided above the traveling device 2
