<Elevation control of auger device and reaping device>
The control cylinder 100 controls the lifting cylinder 41 that moves the auger device 30 up and down and the lifting cylinder 74 that moves the cutting device 80 up and down. As shown in FIG. 5, on the input side of the control device 100, a head height sensor 70, an auger height sensor 35, and an anti-body height sensor that detects the height of the feeder house 40 and the auger device 30 relative to the body. 101, a pressure sensor 102 for detecting the pressure in the elevating cylinder 74, a load sensor 104 for detecting a driving load of the transport device 10, and the like are connected. Further, on the output side of the control device 100, the lifting cylinder 41, the lifting cylinder 74, the notification device 103 that notifies the operator of various information, the cutting blade device drive unit 105 that drives the cutting blade device 20, A transport device drive unit 106 that drives the transport device 10, an auger drive unit 107 that drives the auger 32, a feeder house drive unit 108 that drives the feeder house 40, and the like are connected.

  As shown in FIG. 6, when the lowering operation of the auger device 30 is detected or the auger device 30 is detected to be lowered by the aircraft height sensor 101 (Step S <b> 1), the control device 100 detects the lowering operation of the auger device 30. The reaping device 80 is set to a predetermined posture (step S2).

  This predetermined posture means that the auger of the reaping device 80 is such that the bottom of the auger device 30 is slightly higher than the lower end of the reaping device 80 when the auger device 30 and the reaping device 80 are lowered to a height for harvesting. For example, the bottom wall of the auger frame 31 is 50 mm away from the ground in a state where the lower end portion of the weed body 56 of the reaping device 80 is installed on the ground. That is, in step S2, the control device 100 operates the elevating cylinder 74 so as to be in the above-described predetermined posture, and raises and lowers the reaping device 80.

  When the auger device 30 is lowered while adjusting the posture of the reaping device 80 as described above and the height sensor 101 detects that the height of the auger device 30 is less than a predetermined value (step S3), control is performed. The apparatus 100 starts automatic height control based on the detection values of the head height sensor 70 and the auger height sensor 35 (step S4). That is, the control device 100 determines that the height detected by each of the head height sensor 70 and the auger height sensor 35 approaches the target value set in advance for each sensor. To control.

  If the auger height sensor 35 is in a state where it does not detect the ground while the automatic height control is being executed, that is, the auger device 30 moves away from the ground beyond the ground detection range by the auger height sensor 35. (Step S5) When the head height sensor 70 is detecting the ground (Step S6), the control device 100 raises the mowing device 80 by a predetermined amount or a predetermined time, and then the auger device 30. The auger device 30 is lowered so that the height of the auger falls within the detection range of the auger height sensor 35 (step S9).

  Further, when both the auger height sensor 35 and the head height sensor 70 do not detect the ground (steps S5 and S6), and the height of the machine body is less than a predetermined level (step S7), the auger device 30. The auger device 30 is lowered so that the height of the auger falls within the detection range of the auger height sensor 35 (step S10).

  In step S7, when the height of the aircraft is greater than or equal to the predetermined value, the control device 100 ends the automatic height control (step S8).

  When the automatic height control is being performed and the pressure detected by the pressure sensor 102 of the elevating cylinder 74 fluctuates beyond a predetermined range, the target height of the reaping device 80 is changed to a higher side. Can be controlled.

  Further, when the pressure sensor 102 detects a pressure exceeding a preset normal pressure range, the operator is notified, automatic height control is interrupted, the reaping device 80 or the auger device 30 is raised. It can also be made.

  With the configuration of the control device 100 described above, when the auger device 30 is lowered to the height at which the harvesting operation is performed, the mowing device 80 is automatically set to a predetermined posture. It is possible to prevent damage, crop damage, and damage to the cutting device 80.

  Further, when the auger height sensor 35 does not detect the ground, the auger device 30 is lowered after the reaping device 80 is raised, so the height detected by the head height sensor 70 as the auger device 30 is lowered. Compared with the case where the mowing device 80 is raised based on the detection signal, the pruning device 80 can be prevented from entering the soil, and damage to the field and crops, and the mowing device 80 can be prevented from being damaged. it can.

  Further, when both the auger height sensor 35 and the head height sensor 70 do not detect the ground, the auger device 30 is lowered, so that the lowering of the reaping device 80 is delayed and crops are lost (so-called head loss). Less likely to occur.

<Driving control of reaping device>
The reaping device 80 and the auger device 30 are controlled to start and stop driving and control the driving speed based on the installation state and the lifted state.

  As shown in FIG. 7, when the cutting device 80 is lowered and the head height sensor 70 detects the ground (step S11), that is, the grounding body 71 is not receiving an external force, and thus is grounded by contact with the ground. When detecting that the body 71 is rotated upward, the control device 100 starts driving the transport device 10 and the feeder house 40 (step S12).

  The control device 100 measures the time from the time when it is grounded. Then, when the measurement time reaches the set time or when the lowering of the cutting device 80 stops (step S13), the cutting blade device 20 and the auger 32 are started to be driven (step S14). In steps S12 and S14, it is also possible to start driving the respective devices at different timings rather than simultaneously.

  In addition, in step S11, it can also be made into the conditions that the distance in the height direction of the grounding body 71 and the cutting device 80 became below the setting value.

  In addition, each device of the pre-cutting processing device 3 is driven at each reference speed determined by the setting based on the type of crop and the traveling speed of the machine body. As shown in FIG. 9, when driving of the pre-cutting processing device 3 is started, first, when driving of the transport device 10 is started (step S31), the second transport device 10B on the right side is driven at a higher speed than the first transport device 10A on the left side. (Step S32). That is, in the transport apparatus 10 having a plurality of transport mechanisms, the leftmost one is driven at the reference speed, and the right one is driven at a higher speed. When the drive of the auger 32 is started (step S33), the auger 32 and the feeder house 40 are driven at a speed higher than the reference speed (step S34).

  Then, when a predetermined time has elapsed from the start of driving of the conveying device 10 (step S35), each device of the pre-cutting processing device 3 is driven at the respective reference speed (step S36). In addition, when the load by the load sensor 104 of the conveyance apparatus 10 is larger than the setting range at the time of acceleration of each apparatus, it can also decelerate.
