Further, when the operation of the clutch lever 30 to the second working position is detected by the clutch sensor 31, the operation of the clutch motor 28 causes the second cam 41 to rotate to the above-described mowing position, thereby causing the first spring to rotate. The connection state of the cutting clutch 14 against the bias of 69, the connection state of the threshing clutch 19 against the bias of the second spring 70, and the connection state of the feed chain clutch 25 by the bias of the third spring 71 The cutting and conveying unit 3 and the threshing device 5 are driven so as to show a cutting and threshing operation state (see FIG. 13).
[0056]
In this cutting and threshing operation state, when the execution of the automatic clutch control is selected by the operating tool 72, the height sensor 33 detects the rise of the cutting and conveying unit 3 at a predetermined height position or more. By operating the clutch motor 28, the second cam 41 is rotated to the above-described mowing / conveying stop position, so that the mowing clutch 14 is disconnected by the urging of the first spring 69 and the second spring 70 is energized. The connected state of the threshing clutch 19 and the cut-off state of the feed chain clutch 25 against the urging of the third spring 71 appear, and the drive of the feed chain 20 in the mowing transport unit 3 and the threshing device 5 is stopped. (See FIG. 14).
[0057]
In this cutting / transporting stopped state, when the height sensor 33 detects that the cutting / transporting unit 3 is lowered below the predetermined height position, the clutch motor 28 operates to move the second cam 41 to the above-described cutting / removing position. By rotating, the mowing transport unit 3 and the feed chain 20 are driven again to reproduce the above-mentioned mowing and threshing work state (see FIG. 13).
[0058]
Note that, in both the first linkage state and the second linkage state, when the execution stop of the automatic clutch control is selected by the operation tool 72, the cutting and threshing work state based on the detection of the height sensor 33 and the cutting The transfer stop state is not switched to appear.
[0059]
That is, in the first linkage state in which the cam mechanism 27 is equipped with the first cam 40, the control device 29 switches between the work stop state, the cutting work state, and the cutting and threshing work state based on the operating position of the clutch lever 30. And a switch between a cutting and threshing operation state based on the detection of the height sensor 33 and a cutting and conveying stop state, and the second linkage state in which the cam mechanism 27 is equipped with the second cam 41 is possible. Based on the operation position of the clutch lever 30, the state switches between the work stop state, the threshing work state, and the harvesting and threshing work state, and at the same time, switches between the harvesting and threshing work state based on the detection of the height sensor 33 and the cutting and conveying state. Switching appearance is possible.
[0060]
From the above configuration, at the start of the harvesting operation in each field, when the entering harvesting operation (see FIG. 15) for cutting the planted grain culm at the ridge while the aircraft enters the field is performed, the state of the harvesting operation appears. If the state is switched to the first linked state, the harvesting operation state appears, so that the harvesting and transporting unit 3 harvests the planted cereal culm on the ridge as it enters the field, and the rear threshing device In this approach cutting operation, dust such as straw chips and the like generated in the threshing device 5 by the harvesting operation in the previous field is discharged outside the machine while allowing the entry cutting operation to be carried toward the field 5. The inconvenience of scattering to nearby private houses and roads can be avoided.
[0061]
In the case of performing a so-called pillow-handling operation in which the stalks cannot be cut by the cutting and transporting unit 3 and hand-cutted culms are manually supplied to the threshing apparatus 5, the state is switched to the second linkage state in which the threshing operation state can be displayed. When the threshing operation state appears, the feed chain 20 guides the tip side of the hand-cut grain culm into the threshing device 5 with the manual supply of the hand-cut grain culm, and the feed chain 20 moves to the tip side. On the other hand, the threshing device 5 performs threshing and sorting to collect the grains and perform threshing using a pillow for discharging dust such as straw chips outside the machine. It is possible to avoid a power loss due to the driving of the turret 3 and an inconvenience of feeling a sense of fear due to the driving of the reaping transport unit 3 when the operator manually supplies the hand-cutting grain culm to the threshing device 5. .
[0062]
In both the first linked state and the second linked state, the harvesting and threshing work state can be displayed. By displaying the harvesting and threshing work state, the harvesting and transporting is performed as the machine body travels. The section 3 cuts the planted grain culm and conveys it to the rear threshing device 5, and the feed chain 20 receives the cut grain culm from the cutting and conveying section 3 and guides the front end thereof into the threshing device 5. The threshing apparatus 5 performs the threshing and sorting processes on the tip side to collect the kernels and perform the normal operation of discharging dust such as straw chips outside the machine.
[0063]
In this normal work, when the harvesting work on the current work path is completed and a direction change such as a headland turn is performed to move the aircraft to the next work path, execution of the automatic clutch control is selected by the operating tool 72. In this case, the above-described cut-and-conveying stop state appears with the raising operation of the cutting and conveying unit 3 to a height position equal to or higher than a predetermined height position performed at the start of the direction change, and the cutting and cutting operation is performed. While the cutting and conveying of the grain culm by the conveying unit 3 and the feed chain 20 is stopped, the threshing process and the sorting process by the threshing device 5 are continued, and the setting of the cutting and conveying unit 3 performed after the direction change is set in advance. With the lowering operation to the height position lower than the predetermined height position, the above-described cutting and threshing operation state is reproduced, and the cutting and conveying unit 3 and the feed chain 20 cut the culm. Since the transport is resumed, the continuous transport state of the harvested grain culm by the harvesting transport unit 3 and the feed chain 20 is maintained even when the direction change in which the transplanted grain culm that shifts the work route is not performed is performed. It is possible to avoid the occurrence of jamming and threshing failure caused by the disturbance of the conveying posture of the harvested culm due to the interruption of the continuous conveyance, and at the time of the direction change, the handling cylinder 21 of the threshing device 5 and the Karamin 22 This also makes it possible to avoid threshing failure, sorting failure, and the like, which may be caused when driving is stopped.
[0064]
Also, while moving the machine straight toward the ridge, the cutting and conveying unit 3 is raised so that the tip of each weeding tool 18 moves upward along the ridge, and so-called high mowing is performed to cut the planted grain culm at the ridge. In the case of performing, if the execution stop of the automatic clutch control is selected by the operating tool 72, the height of the mowing transport unit 3 can be raised to a height position equal to or higher than a predetermined height position when the high mowing is performed. Accordingly, it is possible to avoid the inconvenience that the planted cereal culm at the ridge is left uncut and pushed down by the cutting and conveying unit 3 which is caused by the appearance of the above-described cutting and conveying stopped state.
[0065]
The cam mechanism 27 has an output gear 73 integrated with the driven gear 39 and a relay gear 74 that meshes with the output gear 73 to rotate the first cam 40 or the second cam 41. Is provided with a rotation sensor 75 composed of a potentiometer that detects the rotation of the first cam 40 or the second cam 41 based on the detection of the rotation sensor 75. It is configured to detect. In addition, the predetermined height position of the mowing transport unit 3 can be changed to a desired height position by rotating a setting device 76 including a potentiometer mounted on the boarding operation unit 7.
[0066]
As shown in FIG. 1 and FIG. 3, the harvesting / transporting unit 3 includes a stock sensor (an example of a grain / crumb sensor) including an on / off switch for detecting the supply of the planted cereal culm to the cutting / transporting unit 3 as the machine body travels. 77, a pair of left and right tip sensors (an example of a grain culm sensor) 78 comprising an on / off switch for detecting the tip position of the harvested grain culm with respect to the threshing device 5, and the grain culm transport device 17 of the reaping transport unit 3 are independently raised and lowered. The control device 29 controls the operation of the lifting / lowering motor 79 based on the detection of the pair of left and right tip sensors 78. The transport start end position of the grain culm transport device 17 with respect to the grain culm before transport is changed so that only the tip sensor 78 located on the stock side detects the harvested grain culm. Culm It is configured to perform the squeezing depth control to maintain the previously positioned in the proper position.
[0067]
In addition, when the cutting sensor 78 (an example of a grain culm sensor) detects a cutting grain culm during the above-described approach and harvesting operation, the control device 29 operates the clutch motor 28 to operate the cutting and conveying unit 3 and the threshing device. 5, the transmission to the left and right crawler-type traveling devices 1 is activated by operating an electric transmission motor 80 for operating the hydrostatic stepless transmission 8 to stop the transmission to the crawler-type traveling device 1. The neutral state of the hydrostatic continuously variable transmission 8 to be shut off is displayed, and an alarm device 81 such as a buzzer or a lamp mounted on the boarding operation unit 7 is operated.
[0068]
Further, the control device 29 detects the driving state of the left and right crawler-type traveling device 1 by the traveling sensor 32, and detects the supply of the planted cereal culm to the cutting and conveying unit 3 by the stock sensor 77, while cutting. When the connected state of the clutch 14 is revealed, the cut-off sensor 82, which is turned on and off by the tension arm 43, detects the drive stop state of the cutting and conveying unit 3 when the cut-off sensor 82 is turned on. In this way, the neutral state of the hydrostatic continuously variable transmission 8 that interrupts the transmission to the left and right crawler-type traveling devices 1 appears, and the alarm device 81 is operated.
[0069]
With this configuration, if the operator forgets to perform the operation of switching from the harvesting operation state to the harvesting and threshing operation state by the clutch lever 30 for changing the operation state from the entering harvesting operation to the normal operation, the operator recognizes that the switching operation has been forgotten. And the culm in the harvesting and transporting unit 3 caused by the fact that the threshing device 5 is stopped driving despite the fact that the harvested cereal culm reaches the threshing device 5 caused by forgetting the switching. Clogging can be avoided beforehand. In addition, since the tip sensor 78 originally provided in the reaping and transporting unit 3 is effectively used to perform the above-described handling depth control, the configuration can be simplified and the manufacturing cost can be reduced.
[0070]
Further, the driving operation of the cutting and conveying unit 3 is performed at the time of the ingress cutting operation, the normal operation, and the high cutting operation in which the left and right crawler type traveling devices 1 are driven and the planted grain culm is supplied to the cutting and conveying unit 3. When the operator forgets to drive, the operator can recognize that the driver has forgotten to drive, and also causes the cutting and transporting unit 3 to push down the planted grain culm or the planting by the left and right crawler-type traveling devices 1 caused by the drive forgetting. Stepping on the cereal stem can be avoided beforehand.
[0071]
As shown in FIG. 3, the speed change motor 80 is operated by a speed change linkage mechanism 83 extending from the speed change lever 11 to the hydrostatic type continuously variable transmission 8, and a manual speed change operation of the hydrostatic type continuously variable transmission 8 is performed by the speed change lever 11.
