  The steering unit 5 has a seat 5b mounted on an upper part of an engine cover that covers the engine inside the cabin 5a, and the right and upper surfaces of the front operation panel disposed in front of the seat 5b And a steering lever 5c which can adjust the reaping device 4 up and down. A handle 5d is provided so as to bypass the rear side of the steering lever 5c, and a wrist pad 5e is attached to the rear side of the steering lever 5c on the handle 5d. Further, on the side of the seat 5b, a main transmission lever that performs a shift operation of a hydrostatic continuously variable transmission that inputs driving force to the transmission case, and an auxiliary transmission lever that switches the transmission of an auxiliary transmission mechanism in the transmission case. A reaping clutch lever for turning on and off the driving of the reaping device; a threshing clutch lever for turning on and off the driving of the threshing device 2; an operation lever for turning and raising and lowering the grain discharging cylinder 3c; An expansion / contraction operation switch for extending / contracting the cylinder 3c and a discharge clutch lever for turning on / off the bottom transfer spiral of the storage part 3b and the discharge spiral in the grain discharge cylinder 3c are provided.

  Thus, electrodes (sweating amount detection means) 6 are provided on the grip portion of the steering lever 5c and the grip portion of the main transmission lever, respectively. The electrode 6 is configured such that an anode and a cathode are arranged at a predetermined interval on a continuous surface of each gripping portion, and when the gripping portion is gripped, the operator's palm is in contact with both poles.

Further, a speaker (generator) 7 for generating sound is attached to a position on the ceiling side of the cabin 5a. The speaker 7 may share a radio / stereo speaker.
Further, in the cabin 5a, an ultrasonic vibrator (generator) 8 for generating aroma is provided inside the air conditioner. The ultrasonic vibrator 8 pulverizes the liquid fragrance stored in the container finely by ultrasonic vibration, and sprays it into the cabin 5a together with the blown air from the air conditioner. As this fragrance | flavor, what contains fragrance components, such as a herb and a flower utilized for what is called aromatherapy, is utilized. With this scent component, nerve sedation and stress reduction can be achieved.

As shown in FIG. 3, the electrode 6 is connected to the input side of the controller (control means) 9, while the speaker 7 and the ultrasonic vibrator 8 are connected to the output side.
As a result, when the operator grips the grip portion of the steering lever 5c or the grip portion of the main transmission lever, the electrode 6 comes into contact with the palm of the pilot and is short-circuited by the sweat of the palm. The energization amount (resistance value) varies depending on the amount of sweating. That is, the amount of sweating is detected by the change in the energization amount.

  When the detected perspiration amount exceeds the reference perspiration amount set in the controller 9, an output is made from the controller 9 to the speaker 7 and the ultrasonic vibrator 8, and the stress relaxation means 8 is activated. To do.

  That is, music that influences the brain and increases the α wave in the brain wave, such as classical music, flows from the speaker 7. This music is stored in the controller 9, but a player may be provided as an external device of the controller 9 and a music CD may be set. Moreover, it is good to comprise so that music selection according to a driver | operator's liking can be performed.

  Further, the ultrasonic vibrator 8 is activated by the output to the ultrasonic vibrator 8, and the fragrance stored in the container is atomized, mixed in the air blow from the air conditioner, and jetted into the cabin 5a. The By sucking this, the driver's nerve is sedated and stress is relieved or reduced.

  Thus, in addition to the above configuration, a temperature sensor (atmosphere temperature detection means) 10 for detecting the outside air temperature and a humidity sensor (atmosphere humidity detection means) 11 for detecting the humidity are further provided in the cabin 5a. The temperature sensor 10 and the humidity sensor 11 are connected to the input side of the controller 9. Thereby, the stress relaxation system shown in FIG. 3 is configured.

  Accordingly, the outside air temperature and humidity in the cabin 5a are detected by the temperature sensor 10 and the humidity sensor 11, and the reference sweating amount is corrected according to the detected outside air temperature and humidity. That is, FIG. 4 shows a graph in which the horizontal axis represents the outside air temperature and the vertical axis represents the perspiration amount. When the perspiration amount change line PO accompanying the outside air temperature change is conceptually represented, from 25 degrees Celsius. In the range up to 35 degrees Celsius, the correction line PO2 is set by doubling the rate of increase in sweating due to stress to the rate of increase in sweating on this line PO1. Then, the difference between the sweating amount obtained from the line PO1 and the sweating amount obtained from the correction line PO2 at the same outside air temperature is calculated, and the reference sweating amount is corrected by this difference. That is, correction is performed to increase the reference sweating amount as the outside air temperature rises.

  FIG. 5 shows a graph in which the horizontal axis represents the outside air humidity and the vertical axis represents the perspiration amount. When the change line PS1 of the perspiration amount accompanying the outside air humidity change is conceptually represented, the humidity is 50%. In the range of up to 100% humidity, the correction line PS2 is set by doubling the rate of increase in sweating due to stress to the rate of increase in sweating on this line PS1. Then, the difference between the sweating amount obtained from the line PS1 and the sweating amount obtained from the correction line PS2 at the same outside air humidity is calculated, and the reference sweating amount is corrected by this difference. That is, correction is performed to increase the reference sweating amount as the outside air humidity increases.

4 and 5 conceptually represent the relationship between the outside air temperature or outside humidity and the amount of sweating, and are determined by actually measuring the amount of sweating and obtaining basic data.
The above has shown a configuration for detecting the operator's stress based on the measurement of the amount of sweating. Next, another means for detecting the operator's stress will be described.

  FIG. 6 shows a front view and a side view of the steering lever 5c. Two limit switches 13L and 13R for detecting the left and right tilt of the steering lever 5c are arranged on the left and right sides of the left and right tilt fulcrum shaft 12 of the steering lever 5c, and the left and right limits are controlled by the left and right tilt operation of the steering lever 5c. When either one of the switches 13L and 13R is turned on, the side clutch in the transmission case is disconnected by the output from the controller, the transmission of the driving force to the wheel sprocket 1a on the operating side is cut off, and the traveling direction of the vehicle body Is configured to be steered to this side. Reference numeral 14 denotes a front / rear tilting fulcrum shaft of the steering lever 5c. By tilting the steering lever 5c in the front / rear direction, oil is fed to the cylinder for driving the lifting / lowering device 4 so that the cutting device 4 can be arbitrarily set. Can be moved up and down.

  Then, as shown in FIG. 7, the left and right limit switches 13L and 13R are connected to the controller 15 on the input side, while the buzzer 16 and the monitor 17 are connected to the output side to detect the fatigue level. -Configure a notification system. The controller 15 includes an operation frequency (limit switches 13L, 13R per unit time or per unit travel distance) of the steering lever 5c during a normal cutting operation in a state where the operator who uses this combine is not tired. The number of ON / OFF times) is always set while being detected. When the operation frequency falls below a predetermined range during the cutting operation, it is determined that the operator is tired, the buzzer 15 is sounded, and the monitor 17 is “tired. Please display a message such as “Please stop.” Or “Dangerous. Please stop” to prompt the user to interrupt or end the work. Thus, by constantly monitoring the number of operations of the steering lever 5c, it is possible to determine the driver's fatigue and to improve the safety of work travel.

  Next, as shown in FIG. 8, an ultrasonic sensor 18 is attached to the upper front portion of the storage portion 3 b in the combine grain storage device 3, and the ultrasonic sensor 18 allows the operator sitting on the front seat 5 b to It is configured so that the distance to the back of the head or back can be measured.

  Then, as shown in FIG. 9, the ultrasonic sensor 18 is connected to the input side of the controller 19, while the buzzer 20 and the monitor 21 are connected to the output side of the controller 19. Configure. In the controller 19, the memory setting is performed while constantly detecting the distance from the front surface of the storage unit 3b to the back of the driver or the back of the driver in a normal cutting operation in a state in which the driver using the combine is not tired. Keep it. And, during the cutting operation, when the operator becomes sleepy and the posture collapses forward, and the measurement distance by the ultrasonic sensor 18 increases beyond a predetermined range, or when this measurement distance repeatedly increases and decreases In addition, it is judged that the pilot is tired, and the buzzer 20 is sounded, and a message such as “I am tired. Please take a break.”, “It is dangerous. To suspend or end the work. Thus, by constantly monitoring the operator's posture, it is possible to determine the operator's fatigue and improve the safety of work travel.

  Further, as shown in FIG. 10, the operator's fatigue degree is detected from the operation frequency of the steering lever 5c and the attitude detection means of the operator by the ultrasonic sensor 18, and the combine body pitching mechanism is operated. It may be configured. That is, the limit switches 13L and 13R as the fatigue degree detecting means and the ultrasonic sensor 18 are connected to the controller 22 on the input side, while the monitor 23 and the pitching cylinder extending solenoid 24U are connected to the output side. A solenoid 24D for shortening the pitching cylinder is connected. When output to the pitching cylinder extension solenoid 24U, the pitching cylinder is forced to perform a pitching operation so that oil is fed to the pitching cylinder and the front part of the vehicle body is raised, and when output to the pitching cylinder shortening solenoid 24D, the pitching cylinder Therefore, the pitching operation is forcibly performed so that the front portion of the vehicle body is lowered after the oil is returned. This is called a fatigue detection / warning system.

  With this configuration, when it is determined that the pilot is tired, a message such as “I am tired. Take a break.”, “Dangerous. The pitching operation is forcibly performed so that the front part of the vehicle body is raised by being output to the cylinder extending solenoid 24U. As a result, in a state where the driver is fatigued and the reaction becomes dull, by raising the front part of the vehicle body to the set height, the weeding body 4a of the cutting device 4 at the front part of the vehicle body is pushed into the field scene and damaged. Such a trouble can be reduced.

  Further, as shown in FIG. 11, a cutting clutch engagement detection switch 26 for detecting that the cutting clutch lever 25 is turned on is provided at a cutting clutch lever 25 portion that turns the driving of the cutting device 4 on and off. A discharge clutch on / off detection switch 28 for detecting that the discharge clutch lever 27 is turned on is provided at a portion of the discharge clutch lever 27 that turns on and off the grain discharge drive of the grain discharge cylinder 3c provided in the apparatus 3. Then, as shown in FIG. 12, while the controller 29 is connected with the cutting clutch entering detection switch 26 and the discharge clutch entering detection switch 28 on its input side, the buzzer 30 and the monitor 31 are connected on its output side. Connect.

  With this configuration, from the start of the cutting operation when the cutting clutch engagement detection switch 26 is turned on, the cutting clutch engagement detection switch 26 is turned OFF and when the discharge clutch engagement detection switch 28 is turned OFF (the cutting operation is completed). The time until the grain discharging operation is completed is measured, and the work cycle of this one stroke is stored in the controller 29. When this work cycle becomes longer, it is determined that the operator is fatigued and the efficiency of the cutting work is reduced, and the buzzer 30 is sounded to notify the state, and the monitor 31 indicates that “the work efficiency is reduced. "Please take a break.", "I am tired. Please take a break." As a result, the operator can recognize his / her fatigue level and can perform an efficient cutting operation.

  Moreover, you may comprise so that alerting | reporting and a message may be performed when the said work cycle changes long and short. This is because, depending on the operator, when the user is tired, the work cycle may be shortened due to the feeling of frustration.

  Further, as shown in FIG. 13, a fingerprint authentication device 32 is installed in the control unit 5 so as to be able to identify the individual driver, so that the notification can be made individually for each pilot by the change in the work cycle. You may comprise. That is, to the controller 33, the cutting clutch entering detection switch 26, the discharging clutch entering detection switch 28, and the fingerprint authentication device 32 are connected to the input side, and the monitor 34 is connected to the output side of the controller 33. An individual notification system based on authentication is configured. When the driver's fatigue is detected as described above, a message such as “Mr. A, X hours have passed since the start of work. Please take a break.” Is displayed on the monitor 34. To do. Thus, for example, when the pilots A, B, C, and D use this combine, the work cycle can be stored for each individual, so that the fatigue level can be notified appropriately.

  Further, as shown in FIG. 14, a gear portion 5g is formed at the front and rear pivot point of the main transmission lever 5f, and an output gear 36 attached to the output shaft of the transmission electric motor 35 is engaged with the gear portion 5g. . Then, as shown in FIG. 15, the controller 37 is connected to the cutting clutch entering detection switch 26 on its input side, and connected to the output electric motor 35 on its output side to constitute an automatic deceleration system. May be. As a result, when a predetermined time has elapsed after the cutting clutch engagement detection switch 26 is turned on and the cutting operation is started, a deceleration output is made from the controller 37 to the shifting electric motor 35, and the vehicle speed of the combine is automatically set. Decelerated to the set speed. As a result, the vehicle speed is automatically decelerated when the operator is tired, so that the cutting operation can be performed safely. In addition, when a predetermined time has elapsed after the cutting clutch engagement detection switch 26 is turned on and the cutting operation is started, a deceleration output is made from the controller 37 to the shifting electric motor 35 and the speed of the combine vehicle is automatically reduced. And may be configured to reach a stop. As a result, the vehicle speed is automatically decelerated and the vehicle stops in a state where the operator has become tired, so that safety can be improved.

  Also, as shown in FIG. 16, the first work cycle is measured and stored as a standard time, and when the work cycle after the next time is shortened, the shortening ratio is displayed on the monitor. Also good. Thereby, since the pilot can confirm the standard of the working speed at the present time, the driver's own fatigue level can be recognized.

  Moreover, as shown in FIG. 17, with respect to the controller 38, the vibration sensor 39 which detects the vibration of the chamber part in the threshing apparatus 2 on the input side, and the potentiometer 40 which detects the operation position of the main transmission lever 5f are provided. On the other hand, the speed change electric motor 35 may be connected to the output side thereof to constitute an automobile speed reduction system. Thus, when an excessive amount of cereal is supplied to the threshing device 2 and the handling chamber is overloaded, and the vibration sensor 39 detects that abnormal vibration has occurred from the handling chamber, the controller 38 uses the speed changer. A deceleration output is made to the electric motor 35, and the main transmission lever 5f is automatically tilted to the deceleration side. In this way, when abnormal vibration occurs from the handling room, the operator senses the abnormal state and this causes stress, but the vehicle speed is automatically reduced to reduce the amount of supply to the handling room. By reducing it, the overload state in the handling room can be eliminated, so the operator's stress can be eliminated automatically. Further, since the operator does not need to manually decelerate the main transmission lever 5f, the operator can concentrate on the operation of the steering lever 5c and the like.

  In addition, as described above, when abnormal vibration is detected from the handling room, the automatic handling depth control device is controlled to the shallow handling side to reduce overload in the handling room and You may comprise so that an automatic handling depth control apparatus may be returned to the control state by a normal saddle length sensor when a vibration is no longer detected. The vibration sensor 39 is attached to a handling cylinder cover at the upper part of the handling chamber. This eliminates the need for manual handling depth adjustment and improves operability.

  As shown in FIG. 18, the normal handling depth control is performed by setting the state where the tip of the cereal is located between the tip side sensor 41 and the stock side sensor 42 to the neutral state, and the tip side sensor When both 41 and the plant side sensor 42 detect the cereal and are turned on, it is determined to be in the deep handling state and is controlled to the shallow handling side, and both the tip side sensor 41 and the stock side sensor 42 are controlled. Is a configuration in which when it is turned off without detecting the cereal, it is determined to be in a shallow handling state and is controlled to the deep handling side. However, as shown in FIG. 19, the vibration sensor 39, the tip side sensor 41, and the stock source side sensor 42 are connected to the controller 43 on the input side, while the handle depth adjustment is performed on the output side thereof. A motor 44 may be connected to constitute a system for relieving stress due to handling room overload. Thus, when abnormal vibration of the handling room is detected by the vibration sensor 39, the output on the shallow handling side is switched from the normal handling depth control state until the stock-source side sensor 42 that has been in the ON state is switched to OFF. Is done. As a result, the amount of grain tip thrusting into the handling room is reduced, the load in the handling room is reduced, abnormal vibration in the handling room is reduced, and the operator's stress is reduced.

  FIG. 20 shows the configuration of the pulling device 4b in the reaping device 4. The pulling device 4b has a drive sprocket 4b3 mounted on the drive shaft 4b2 at the upper part of the pulling case 4b1, and supports the idler roller 4b4 at the lower part thereof. The drive sprocket 4b3 and the idler roller 4b4 And a chain 4b6 around which a large number of lugs 4b5 are axially wound. A torque sensor 45 is provided on the drive shaft 4b2, and the torque sensor 45 causes the load to be detected. This raising load becomes small in the posture in which the planted culm stands up, and increases in the posture in which the planted culm is lying down. As shown in FIG. 21, the torque sensor 45 is connected to the input side of the controller 46 and the monitor 47 is connected to the output side of the controller 46, thereby constituting a stress notification system based on the induced load. As a result, the torque sensor 45 causes the load to be detected, and the monitor 47 displays a message such as “The grain has fallen down. Please decelerate the vehicle speed.” As a result, it is possible to reduce problems such as the operator forcibly performing the cutting operation, clogging the cereals in the cutting device 4 or the handling room, or damaging the cutting device 4.
