About the. 2. Description of the Related Art In a combine operation, a mowing device is moved forward and backward with respect to a vehicle body.
Or, it is displaced in the left and right directions to facilitate the harvesting work at the ridge or the corner of the field. However, in a mode in which the mowing device is moved with respect to the vehicle body, the upper side of the support connection portion of the mowing device with respect to the vehicle body is difficult to take a complicated configuration because the harvested grain culm is transferred to the rear threshing device. Since the mowing device is heavy, it is difficult to move the mowing device easily.
According to the present invention, in order to solve such a defect, the mowing device is supported by a crank-shaped mowing frame, and the position of the mowing device is changed right and left and back and forth by rotating a crank-shaped portion of the mowing frame.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A combine is equipped with an engine, a control device, a threshing device 7, a paddy tank and the like on a vehicle body 8 having a pair of right and left crawlers 12, and is mounted on a support bracket 13 at a front portion. The rear upper end of the mowing frame 6 is supported around the shaft 14 so as to be vertically rotatable. The transmission case 15 at the front of the vehicle body 8 receives the power from the engine and
A transmission mechanism for transmitting the driving sprocket 16 of the
An input shaft 19 on the elevating shaft 14 is transmitted from a part of the transmission mechanism via a power take-off shaft 17 and a belt 18, and from the input shaft 19 via a transmission mechanism inside the mowing frame 6,
The mowing device 5 is configured to transmit power. In the cutting frame 6, the upper frame 9 and the lower frame 10 are formed in a pipe shape, and the two frames 9, 10 are rotatably connected to each other by a transmission case which is a crank-shaped portion 11. The lower frame 10 side around the axis is rotatable. The transmission shafts 20 and 21 are supported along these frames 9 and 10 and are interlocked with the gears 22 and 23 in the crank-shaped portion 11 so that the transmission shafts 20 and 21 move from the transmission shafts 20 to 21 at any rotation position of the crank-shaped portion 11. Can be transmitted. In the lower frame 10, a cereal stem raising device 2 having a cereal stem raising lug 1, which can work by receiving the transmission from the transmission shaft 21, a cutting blade device 3 in the form of a clipper, and harvested cereal stems are collected at the rear. A feeding device 4 or the like for feeding is provided, and reaping of a predetermined width can be performed. 24 is a weeding frame, 25 is a cutting blade frame integrated with the lower frame 10, and the cutting blade device 3 is provided along the front side of the cutting blade frame 25, and supports the grain stem raising device 2 above. A raising post 26 is provided.
The structure is such that the cereal stem raising rug 1 is driven and rotated via the internal transmission mechanism. The rotation of the crank 11 may be performed by a mechanical operation, but is performed by control motors M1 and M2. Control motor M1 is mounted on the upper frame 9 side, a configuration in which a gear 27 driven by the control motor M 1 into a crank-like portion 11, a crank-shaped portion 1 by driving the control motor M1
1 is pivoted about the upper frame 9. Further, the control motor M2 is provided on the side of the crank-shaped portion 11, and the gear 28 driven by the control motor M2 (may be an operation gear device).
It is provided on the lower frame 10 side, and the mowing device 5 is corrected and maintained in a horizontal position by the rotation of the lower frame 10 with respect to the crank-shaped portion 11 by driving the control motor M2. The rotation position of the crank-shaped portion 11 of the mowing frame 6 can be fixed at a predetermined position such as the left, right, front and rear positions A, B, C, and D. May be provided with a locking mechanism or the like. If the rotational position of the crank-shaped portion 11 is unstable, the mowing device 5 remains in a rotatable state with respect to the upper frame 9 or the lower frame 10 and becomes unstable. The rotation positioning of the crank-shaped portion 11 and the rotation positioning of the lower frame 10 with respect to the crank-shaped portion 11 are performed, or
The structure is such that the cutting blade frame 25 and the like of the mowing device 5 are fixed directly from the vehicle body 8 side. The raising and lowering of the mowing device 5 is performed by the front end of the vehicle body 8 and

9. Reference numeral 30 denotes a feed chain of the threshing device 7, which thresh the ears by rotating the handling cylinder of the threshing device 7 while transferring the culms transferred by the cereal culm transferring device 31 at the rear of the mowing device 5 while transferring. The traveling transmission mechanism of the transmission case 15 is configured to interlock with the sprocket 16 via a combination of a hydraulic continuously variable transmission HST and a differential gear device 33 from an input shaft 32 input from the engine side. In a transmission mechanism that transmits power from the hydraulic continuously variable transmission HST through the differential gear device 33, the differential gear device 33 is switched between high speed H and low speed L, so that the differential gear is used during high-speed traveling such as traveling on a road. Transmission of the continuously variable transmission by the hydraulic continuously variable transmission HST is performed via the high speed H of the device 33, and during low-speed traveling such as combine operation, the continuously variable transmission HST is transmitted via the low speed L of the differential gear device 33. Step transmission is performed. [0013] Thus, the capacity of the hydraulic continuously variable transmission HST may be small, it can be made compact, and the cost can be reduced. Also, the conduction efficiency is improved. Transmission case 15

Forward / reverse switching shaft 4 having forward gear 40 and reverse gear 41 meshed and transmitted from outer shaft 39 meshing with each planetary gear 38
2, a clutch shaft 43 gear-linked from the forward / reverse switching shaft 42, and a left and right clutch gear 4 on the clutch shaft 43.
Intermediate shaft 47 on which an intermediate gear 46 meshing with the gears 4 and 45 is mounted.
And so on. The differential shaft 37 is provided with a switching gear 49 which is always integrally rotated and can directly mesh with the gear 48 of the input shaft 32. The switching gear 49 is moved in the axial direction to mesh with the gear 48. Is removed, the brake claw 50 engages with the brake claw 51 of the transmission case 15 so that the rotation of the differential shaft 37 is not performed. Thus, in a state where the brake claw 50 is engaged with the 51, The outer shaft 39 of the differential gear 33 transmitted from the hydraulic continuously variable transmission HST is interlocked at a low speed L,
When the switching gear 49 is engaged with the gear 48, the differential shaft 3
By the rotation of 7, the rotation of the outer shaft 39 also becomes a high-speed H rotation region. Numeral 52 denotes an intermediate shaft, which comprises an outer shaft 39 and a forward gear 40.
And an intermediate gear 53 interlocking between the two. Forward gear 4
0, and the reverse gear 41 may have a clutch with the shaft 42 to switch to a state in which the rotation of either side can be transmitted. A configuration that can be selected may be adopted. The gear ratio between the forward gear 40 and the reverse gear 41 is different, and the transmission lever 54 and the like for operating the hydraulic continuously variable transmission HST are interlocked with the electromagnetic valve 55 and the like. In the high-speed H transmission range, the reverse R by the reverse gear 41 is made slower than the forward F to provide a safe transmission ratio. The clutch shaft 43 includes a steering clutch gear 4.
By turning off the gears 3 and 44 and further operating in the same direction, the steering brake 55 is applied to prevent the inner crawler 12 from turning around during steering, thereby enabling a sharp turn. 6, the relationship between the forward speed and the reverse speed with respect to the operation angle from the neutral position N to the forward rotation side and the negative rotation side from the neutral position N is as shown in the low speed L range line and the high speed H range line.
