The body 21 is moved forward to cut the planted cereal culm by the reaper 1, and at the time of this reaping, one row at the center and five rows of cereal culms at each of the left and right sides are raised to the left, the middle, and the right. Part 1
2 and at the same time, the root side is squeezed by the left, middle and right rake belts 41, and the squeezed root side is pinched by the rake star wheels 42 and cut at the same time. The cutting is performed by the blade portion 13.

The harvested stock side is collected and conveyed by the stock conveyer chain 43 of each of the left, middle and right stock concentrators.
The confluence is taken over to the supply adjusting chain 47 via the handling depth adjusting chain 44 via the handling depth adjusting chain 44, and while the handling depth is being adjusted, it is transported and supplied to the threshing apparatus 2 and the tip side is collected at each of the left, middle and right ear tips. The confluence is collected by the ear tip transport lug 46c and joined to the middle position of the right ear tip transport lug 46c, and further conveyed to the threshing apparatus 2 from the junction by the right ear tip transport lug 46c.

When cutting is performed at the edge of a row in such combine work, first, as shown in the flowchart of FIG. 1, information on various sensors and switches is read, and the row-side control switch 3 is turned on. Then, the cutting height position when the cutting device 1 is raised by operating the power steering lever 59 on the ridge side is detected by the cutting height position sensor 57. (At the time of ridge control, the detection value by the handling depth adaptive sensor 56 is ignored.) The front of the grain culm sensor 53 is ON, the cutting height is, for example, 20 cm or more, and the culm length sensor 5
If the culm length of the mowed grain culm detected by step 5 is, for example, 60 cm or more, the handling depth adjustment chain 44 is adjusted to the deep handling side for a certain time according to the culm length, and the culm length is 60 cm or less. If the handle depth adjusting chain 44 is adjusted to the deepest handling side, the supply adjusting chain 47 is adjusted to the position where it is supplied to the threshing short culm chain 9a. When the cutting automatic stop switch 4 is simultaneously turned on during the ridge control, the automatic stop height of the reaper 1 for stopping the driving of the reaper 1 and the feed chain 9 by this ON is set to the ridge control switch 3. From the reference height position B, which is automatically stopped when is OFF, to the upper height position Ba, which is higher than the predetermined height position A at the time of the ridge control by the operation of the stop position changing means 5, and this condition is set. Is satisfied, the cutting clutch 62 and the chain clutch 63 are cut off and output.

As described above, the O of the automatic cutting stop switch 4 is
When the ridge control switch 3 is turned off, the height at which the mowing device 1 is automatically stopped is set to a relatively low reference height position B when the ridge control switch 3 is turned off. Work efficiency is not hindered, and when the ridge control switch 3 is ON, the drive of the reaper 1 is automatically stopped by changing the reference height position B to the upper height position Ba. Thus, problems such as pushing down the culm can be prevented.

As shown in the flowchart of FIG. 10, information of various sensors and switches is read,
While storing the position of the handling depth position sensor 58,
When the control switch 3 is turned on, the cutting height position sensor 5 is turned on.
When the predetermined height position A of the mowing device 1 is detected by 7, the handle depth adjustment chain 44 is adjusted and controlled to the deep handling side. Next, when the ridge control switch 3 is turned off to terminate the ridge harvesting operation, and when both the front 53 and the rear 54 of the culm sensor are not detected, they are stored before the start of the ridge control. The handling depth adjusting chain 44 is returned and controlled by the handling depth adjusting motor 45 so that the handling depth adjusting chain 44 is located at a position on the handling side with a certain depth from the position of the handling depth position sensor 58.

As described above, at the end of the mowing operation at the ridge, the handling depth adjusting chain 4 which has been adjusted and controlled to the deep handling side.
By returning the return position of No. 4 to a position that is a certain amount deeper than the position stored before the start of the ridgeline control, the position was returned to the position before the start of the ridgeline control as in the related art. It is possible to suppress spilling of the culm at the handover part and unhandled remaining due to shallow handling, which have been caused by thinning of the transported grain culm when re-entering the uncut part due to oblique cutting or the like.

A culm length sensor 55 for detecting the length / shortness of a cereal culm arranged in the cereal culm passage above the raising portion 12 of the mowing apparatus 1 at the time of the ridge control as described above,
As shown in FIG. 11, at the time of raising the grain culm in the raising part 12, in the long culm, the grain culm abuts on the detection rod 55a of the culm length sensor 55, the normally open circuit closes and turns on, and the long culm is detected. In the short culm, the detection rod 55a did not come in contact with the cereal culm, and the circuit remained open and turned off to detect the short culm.

However, in the case where the circuit of the culm length sensor 55 is turned off when a short culm is detected as described above, the off state is maintained in the event of a failure due to disconnection of the circuit, etc. There is a problem that the adjustment chain 47 is fixed while being adjusted on the deep handling side. For this reason, by changing the culm length sensor 55 to a normally closed circuit, the circuit remains closed when the cereal culm does not come into contact with the detection rod 55a, and the circuit stays ON when the culm comes into contact with the long culm. Since the circuit is opened and becomes the OFF state, when the circuit breaks due to disconnection of the circuit or the like, the state becomes the same OFF state as when the long culm is detected, and the work can be continued with the normal handling depth for the time being.

As shown in the flowchart of FIG. 12, when the ridge control switch 3 is ON, the motor limit switch 50 of the supply adjusting motor 49 is ON at the deep handling side of the supply adjusting chain 47, When the main switch 60 is turned on in the ON state after the culm sensor 54, the information of the sensors and switches is read, and the supply adjusting chain 47 is deeply handled by the cereal culm detection information by the culm sensor rear 54. It is configured to be adjusted to the cut side.

With this configuration, the ridge-side control switch 3 is
When the main switch 60 is switched from OFF to ON while the supply adjustment chain 47 is in the deep handling side in the N state,
As in the prior art, the supply adjustment chain 47 and the supply adjustment motor 49 are overloaded because the supply adjustment chain 47 attempts to return from the deep handling side to the standard side while the grain stem remains in the supply adjustment transport unit 15. Phenomenon can be prevented. (See FIG. 2) As shown in the flowchart of FIG. 13, when the ridgeline control switch 3 is ON, the motor limit switch 5
0 is ON state on the deep handling side of the supply adjustment chain 47,
When the main switch 60 is turned on in a state where the tip side detection rod 56a or the base side detection rod 56b of the handling depth adaptation sensor 56 is in the ON state, the information of each sensor / switch is read and the handling depth adaptation is performed. The supply adjusting chain 47 is configured to be adjusted to the deep handling side according to the grain stem detection information from the sensor 56.

With this configuration, the ridge-side control switch 3 is
When the main switch 60 is switched from OFF to ON while the supply adjustment chain 47 is in the deep handling side in the N state, the supply adjustment chain 47 remains in a state where the grain stem remains in the supply adjustment transport unit 15 as in the related art. Attempts to return from the deep handling side to the standard side, it is possible to prevent the supply adjustment chain 47 and the supply adjustment motor 49 from being overloaded. (Refer to FIG. 2) As shown in the flowchart of FIG.
When the main switch 60 is turned on in a state where 0 is in the OFF state and the value detected by the depth-of-hand position sensor 58 is on the deep-hand side, information on each sensor / switch is read and the The supply adjusting chain 47 is adjusted to the deep handling side based on the detection information of the position sensor 58 on the deep handling side.

With this configuration, the ridgeside control switch 3 is
When the main switch 60 is switched from OFF to ON when the supply adjustment chain 47 is in the deep handling side in the N state, the motor limit switch 50 is turned on in a state where the grain stem remains in the supply adjustment transport unit 15 as in the related art. In the OFF state, the supply adjustment chain 47 and the supply adjustment motor 4 are used in order to return the supply adjustment chain 47 from the deep handling side to the standard side.
9 can be prevented from being overloaded.
(See FIG. 2) As shown in the flowchart of FIG. 15, the main switch 60 is turned on in a state where the ridge control switch 3 is in an ON state and the supply adjusting chain 47 is adjusted to the deep handling side. Then, the information of each sensor / switch is read, and the vehicle speed pulse is input by the vehicle speed sensor 61. However, the supply adjustment chain 47 is moved to the deep handling side until the input passes a predetermined time. It is configured to be maintained.

With this configuration, the ridge-side control switch 3 is
When the main switch 60 is switched from OFF to ON while the supply adjustment chain 47 is in the deep handling side in the N state, the supply adjustment chain 47 remains in a state where the grain stem remains in the supply adjustment transport unit 15 as in the related art. Attempts to return from the deep handling side to the standard side, it is possible to prevent the supply adjustment chain 47 and the supply adjustment motor 49 from being overloaded, and to adjust the supply adjustment when the body 21 starts moving forward. It is possible to smoothly return the chain 47 to the standard side without a grain culm. (Refer to FIG. 2) As shown in the flowchart of FIG. 16, the main switch 60 is turned ON while the ridgeline control switch 3 is ON.
In this case, the information of the sensors and switches is read and output to the deep handling side or the standard side of the supply adjusting chain 47 is performed.
If 0 does not turn on even after a predetermined time elapses, the adjustment to the supply adjustment chain 47 is stopped.

With this configuration, the ridge-side control switch 3 is
If the main switch 60 is switched from OFF to ON while the supply adjustment chain 47 is stopped halfway in the N state, another operation such as putting another hand on the supply adjustment transport unit 15 is performed as in the related art. When the motor limit switch 50 is turned on due to an obstacle, there is a danger that the output may be suddenly output to the supply adjustment chain 47 and the hand may be pinched.
It can be avoided because it does not. (See FIG. 2) As shown in FIG. 17, when the combine enters the farm from a farm road or the like and the farm road is at a higher position than the farm, the reaper 1 is raised because the machine body 21 is inclined in the front-rear direction. To avoid collision with the soil surface.

When the ridge control is turned on at a high position due to the ascent of the mowing device 1, the ridge control is activated and the handling depth adjusting chain 44 and the supply adjusting chain 47 handle the transported grain culm in the deepest position. However, since the actual grain culm is cut with a culm length that is almost normal, the load on the threshing device 2 increases, and there is a possibility that threshing work may be hindered.

For this reason, as shown in FIG. 18, the CPU is mainly arranged to control the operation of the automatic circuit and
Of the body 21 by the front-rear inclination sensor 67 provided at an appropriate position
When a certain inclination state is detected, a controller 69 having a built-in ridge control invalidating means 68 for invalidating the ridge control is provided. To the input side of this controller 69,
The ridge control switch 3, the cutting height position sensor 57, the front-rear inclination sensor 67, and the like are connected via the input interface 69a, and the output interface 69 is connected to the output side.
b, the deep handling adjustment relay 65a, the shallow handling adjustment relay 65b, the supply adjustment relay 66 and the like are connected to each other.

As shown in the flowchart of FIG. 19, when the ridge control switch 3 is in the ON state, the information of each sensor / switch is read, and the longitudinal
When the cutting device 1 is at the high cutting position by the detection of the cutting height sensor 57 when the forward leaning state is detected, the ridge control invalidating means 68 stops the ridge control.

With this configuration, when the combiner enters the field, the ridge control is invalidated when the body 21 is in the forwardly inclined posture and the reaper 1 is lifted up, as in the prior art. Even if the stalk rises, the ridge control acts on the grain stalk that is cut with almost the normal stalk length and adjusts the grain stalk to the deep handling side, without increasing the threshing load and hindering the work, Even when the mowing device 1 is at the high cutting position when the machine body 21 is in the forward leaning posture, the grain stalks are not deeply handled, so that efficient threshing work can be performed.

As shown in FIG. 17, a cutting height sensor 70 for detecting a cutting height by an ultrasonic wave reflected from the soil surface is provided at an appropriate position at the lower end of the cutting device 1.
The cutting height sensor 70 is connected to the input side of the controller 69 as shown in FIG. 18 via an input interface 69a. As shown in the flowchart of FIG.
When the ridge control switch 3 is ON, the information of each sensor / switch is read, and the reaper 1
The cutting height sensor 7 when in the high cutting position
When the detection value by 0 is equal to or less than a predetermined constant value α,
The ridge-side control invalidation means 68 is configured to stop the ridge-side control.

With this configuration, when the machine 21 is inclined forward when the combine enters the field, the mowing device 1 is raised, or when the mowing device 1 is raised by the sinking of the machine 21 in a wet field or the like, the cutting is performed. When the detection value of the height sensor 70 is equal to or less than the certain value α, the ridge control is invalidated and the culm is not handled deeply, so that efficient threshing work can be performed.

As shown in FIG. 17, the front of the grain culm sensor 53 arranged at the lower front end of the mowing apparatus 1 is connected to the above-mentioned FIG.
Is connected via the input interface 69a to the input side of the controller 69 as shown in FIG. As shown in the flowchart of FIG. 21, when the ridge control switch 3 is in the ON state, the information of each sensor and switches is read, and when the mowing device 1 is at the high mowing position by the detection of the mowing height sensor 57,
When the cereal stalk sensor front 53 is OFF, the ridge control is invalidated, and adjustment to the deep handling side of the cereal stalk is not performed,
When the cereal culm sensor front 53 is turned ON, the ridge control is performed.

With this configuration, when the combine 21 enters the field, the mowing device 1 is raised with the body 21 in the forward tilted posture, and when the culm sensor front 53 is OFF, there is no culling culm. Therefore, when the ridge control is invalidated by judging that it is before the harvesting work and the cereal culm sensor front 53 is turned on,
By judging as ridge cutting and executing ridge control,
Execution / invalidation of ridge control can be selected accurately.
