Description

The present invention relates to a combine.

  In a conventional combine, a grain tank for storing harvested grains is arranged on the fuselage frame, and a discharge conveyor for discharging grains to one end side is arranged in the lower part of the grain tank, and one end of the discharge conveyor is arranged. A vertical discharge auger is connected to the side, and a horizontal discharge auger connected to the outside is connected to the upper part of the vertical discharge auger. Grains in the grain tank are discharged from the grain tank to a discharge conveyor, a vertical discharge auger, and a horizontal discharge auger. The grain can be discharged to the outside by passing through the auger, and among the devices constituting the conveyor, devices arranged near the Glen tank (for example, a sorting device, a first conveyor, a second conveyor, From the viewpoint of facilitating maintenance of the cereal conveyor etc.), in order to be able to open the glen tank, the glen tank is centered on the vertical discharge auger. It is that to be able to pivot laterally with.

In such a conventional combine, a weight sensor is provided between the grain tank and the body frame that supports the grain tank, and the weight sensor is used to detect a load applied to the weight sensor from the grain tank storing the grain. By doing so, the weight of the grain stored in the grain tank may be measured. In this case, when measuring the weight of the grain in the grain tank, if the vertical discharge auger is involved in the weight measurement, the grain weight cannot be measured accurately, so the vertical discharge auger side of the grain tank is used as a fulcrum. The other side (the side opposite to the vertical discharge auger side) can be slightly swung around an axis along a direction perpendicular to the vertical direction with respect to the combine, and a weight sensor is placed on the other side of the machine frame. When the glen tank is opened (that is, when the glen tank is rotated laterally around the vertical discharge auger), the vertical discharge auger is the glen tank and the other side of the glen tank is based on the weight sensor. In other cases, the other end of the glen tank is lifted above the weight sensor, and the other end is placed on the weight sensor, so that the vertical discharge auto There was a state that is not involved almost the weight measurement, when measuring the weight of the grain in the grain tank is designed so as to measure the 該穀 product weight at this state.

After the threshing portion 12 threshed, the cereal mash (waste) is transported from the feed chain 9 to the shed chain 18 and released to the field as it is, or cut into pieces by the mashing processing portion 19. It is released while being diffused later.

  In addition, a sorting unit 17 is disposed below the threshing unit 12, and the sorting unit 17 sorts the grain from grains, swarf and the like flowing down from the threshing unit 12. Of the grains and swarf, the sorted grain is a grain tank 13 disposed on the machine body frame 2 and is conveyed to the grain tank 13 supported by the machine body frame 2, and sawdust. Etc. are discharged outside the machine. The grain tank 13 is provided with a grain supply port 13 a, and a milling cylinder 80 is interposed between the grain supply port 13 a and the above-described sorting unit 17. The refined grains sorted in the sorting unit 17 are supplied and stored in the grain tank 13 from the grain supply port 13a.

  The grain tank 13 is disposed on the side of the threshing unit 12, and a cab 14 is disposed in front of the grain tank 13, while a grain discharging device 15 is disposed behind and above the grain tank 13. ing. The grain discharge device 15 includes a vertical discharge auger 15 a and a horizontal discharge auger 15 b, and the vertical discharge auger 15 a is erected on the machine frame 2 behind the grain tank 13. The Glen tank 13 is configured to be pivotable laterally about the vertical discharge auger 15a, and the horizontal discharge auger 15b is configured to be pivotable in the vertical direction by a pivot fulcrum provided on the rear portion thereof. Has been.

  A screw-type discharge conveyor 16 is disposed in the front-rear direction at the inner lower portion of the grain tank 13, and one end of the discharge conveyor 16 is connected to the grain discharge device 15. Thus, after being conveyed from the grain tank 13 to the grain discharging device 15 by the grain discharging conveyor 16 in the grain tank 13, it is discharged to the outside from the front end portion of the horizontal discharging auger 15b through the vertical discharging auger 15a. .

In the grain discharging device 15, the base side of the horizontal discharging auger 15b is pivotally attached to the upper end of the vertical discharging auger 15a so as to be vertically rotatable. An auger elevating cylinder 130, which is an elevating actuator in the combine 201, is configured to be expanded and contracted by switching a hydraulic control valve, and is pivotally attached to a bracket 131 having one end projecting from the side surface of the vertical discharge auger 15a. is, the other end is rotatably pivotally attached to a bracket 132 which is butt set from lateral discharge auger 15b side. Thus, by extending and retracting the auger elevating cylinder 130, the horizontal discharge auger 15b is rotated in the vertical direction. The auger elevating cylinder 130, which is an elevating actuator in the combine 201, is a hydraulic cylinder, but may be other electric or hydraulic motors and is not limited.

  A gear 133a is fitted and fixed in the middle of the vertical discharge auger 15a, and a gear 133b fitted on a rotation shaft 134a of an auger turning motor 134 as a turning actuator is meshed with the gear 133a. Thus, by operating the auger turning motor 134, the vertical discharge auger 15a and the horizontal discharge auger 15b are integrally turned. The auger turning motor 134, which is a turning actuator in the combine 201, is an electric motor, but may be a hydraulic motor or other hydraulic cylinder, and is not limited.

  In this combine 201, the front part of the grain tank 13 (the opposite side to the vertical discharge auger 15a, which is a pivotal fulcrum) is moved forward and downward, even if the grain tank 13 pivots to the side and moves away from the rail on the machine body frame 2. When the Glen tank 13 is returned to the original position without being inclined, it is configured not to rotate while lifting the front part.

With further described, the vertical discharge auger 15a of the upper and the rear portion of the grain tank 13, allowing portion 59 (see FIG. 6) and rotate during grain tank fixing mechanism 60 is provided which will be described later, the outer surface lower portion of the grayed Rentanku 13 Is provided with an operation unit 70 for operating the rotating Glen tank fixing mechanism 60, and the rotating Glen tank fixing mechanism 60 and the operating unit 70 are connected to each other by a connecting member such as a wire. In this way, when the Glen tank 13 is rotated to the side for maintenance or the like, the allowance of the allowance portion 59 is removed and the Glen tank 13 is fixed to the vertical discharge auger 15a.

  That is, the rotating Glen tank fixing mechanism 60 is disposed at the upper part of the gear 133a. As shown in FIG. 6, a guide plate 61 having a substantially U shape in plan view is disposed in the horizontal direction and opened. The side end is bent outward in the left-right direction and is fixed to the rear surface of the glen tank 13 as an attachment portion. The notch of the guide plate 61 is formed so as to match the outer shape of the vertical discharge auger 15a, and a substantially M-shaped receiving body 62 straddles both inner surfaces on the open side of the guide plate 61. It is fixed. The left and right central portions of the receiver 62 are also curved in accordance with the outer shape of the vertical discharge auger 15a, and the vertical discharge auger 15a is formed in a space formed between the receiver 62 and the back of the guide plate 61. Further, a fastening band 63 for fixing is disposed between the inner back portion of the guide plate 61 and the vertical discharge auger 15a.

  In the space between the tightening band 63 and the receiving body 62, the Glen tank 13 is configured to be swingable about the combine width direction axis with respect to the vertical discharge auger 15a. That is, gaps are formed between the fastening band 63 and the vertical discharge auger 15a and between the receiving body 62 and the vertical discharge auger 15a to form the permissible portion 59. The allowance unit 59 allows the Glen tank 13 to swing around the combine width direction axis, and when detecting the weight of the grain in the Glen tank 13 by a weight sensor 32 (see FIGS. 5 and 8) described later, The Glen tank 13 can swing around the axis at least between an empty state and a full state. When the Glen tank 13 and the vertical carry-out auger 15a are integrally rotated, the allowance of the allowance portion 59 that becomes a gap is eliminated by pulling and tightening the tightening band 63 toward the receiving body 62 side. Thereby, the Glen tank 13 and the vertical discharge auger 15a can be fixed.

  The fastening band 63 has a predetermined width in the vertical direction and is longer than approximately half of the outer periphery of the vertical discharge auger 15a, and is formed of an elastic plate. One end of the fastening band 63 is formed on the guide plate 61. It is pivotally connected to a pivot shaft 65 provided on one of the left and right sides, and a pin 66 protrudes outward from the other end, and one end of a wire 64 serving as a connecting member is fixed to the pin 66. Further, a pin 67 protrudes in the vicinity of the pin 66, one end of a spring 68 is locked to the pin 67, and the other end of the spring 68 extends in a direction opposite to the wire 64, so that the guide plate 61 Locked in place. In this way, when the tightening band 63 is biased in the direction away from the vertical discharge auger 15a by the biasing force of the spring 68, that is, in the loosening direction, the clearance between the allowance portions 59 is increased, and the grain overlap is measured. The superposition can be accurately measured so that the tightening band 63 does not contact the vertical discharge auger 15a.

  A wire receiver 69 is disposed in the vicinity of the bin 66 connecting the wire 64, and the wire receiver 69 is integrally provided on the outer surface of the open end of the guide plate 61, and supports one end of the outer. It is guided so that the pulling direction by the wire 64 is substantially tangential to the outer periphery of the vertical discharge auger 15a. On the other hand, the other end of the wire 64 is extended to an operation unit 70 disposed on the lower side of the front portion of the Glen tank 13.

  As shown in FIG. 5, the operation unit 70 includes a Glen tank fixing lever 71 and a lock lever 72 that locks the Glen tank fixing lever 71 in a tightening position. In the operation unit 70, the wire 64 is pulled forward by rotating the Glen tank fixing lever 71 outward, and one end of the fastening band 63 connected to the other end of the wire 64 is pulled. The glen tank 13 is fastened and fixed to the vertical discharge auger 15a by pulling the outer periphery of the vertical discharge auger 15a forward and bringing it into contact with the receiving body 62, thereby eliminating the allowable portion of the allowable portion 59. In order to maintain the tightened state, the hook portion 72 b of the lock lever 72 is engaged with the release lever 71. Thereby, when the Glen tank 13 rotates to the side, the vertical discharge auger 15a and the Glen tank 13 are integrated, and the vertical discharge auger 15a can support the Glen tank 13.

  As shown in FIGS. 1 to 4, a discharge case 136 is provided at the tip of the horizontal discharge auger 15b. In the discharge case 136, a bearing portion made up of a ball bearing or the like is formed to pivotally support a lateral feed conveyor (not shown). The lower surface of the discharge case 136 is opened, and a cylindrical sleeve 137 is attached along the edge of the opening. The sleeve 137 is made of a flexible resin or the like, and the lower end of the sleeve 137 is a grain outlet 138. Thereby, the grain dropped from the lower surface of the discharge case 136 can be concentrated and discharged in the vicinity immediately below the grain discharge port 138 without being scattered around.

  The combine 201 further includes a sensor device 50 including a moisture sensor 35, an inclination sensor 135, and an augerest sensor 54 in addition to the weight sensor 32.

  The weight sensor 32 is of a load cell type that detects a load from the Glen tank 13, is disposed below the front of the Glen tank 13 and on the body frame 2, and is electrically connected to the control device 100. ing. Thereby, the signal (information) regarding the grain weight detected by the weight sensor 32 can be transmitted to the control apparatus 100 (refer FIG. 8) mentioned later. As described above, when the weight tank 32 detects the weight of the grains in the grain tank 13 by the allowance unit 59, the grain tank 13 is at least filled from an empty state. Since the weight sensor 32 can measure the grain weight in the glen tank 13, the vertical discharge auger 15b is hardly involved in the weight measurement. The grain weight can be measured.

  The moisture sensor 35 detects moisture of the grain, and is disposed in the vicinity of the grain supply port 13a in the glen tank 13 as shown in FIG. Although not shown, the moisture sensor 35 is provided with a pair of electrode rollers facing each other so that a part of the grain supplied from the grain supply port 13a flows between the rollers. The pair of electrode rollers are rotated so that the grains flowing in from the grain supply port 13a enter between the rollers, and the electric resistance value of the crushed grains is reduced while crushing the grains between the rotating rollers. It detects and outputs the detected electrical resistance value as a signal (information) relating to the moisture content of the grain, and is electrically connected to the control device 100. As a result, a signal (information) related to grain moisture detected by the moisture sensor 35 can be transmitted to the control device 100.

  As shown in FIG. 2, the tilt sensor 135 is disposed at a substantially central portion of the combine on the fuselage frame 2, and detects the tilt in the combine width direction and the first tilt sensor 135 a that detects the tilt in the front-rear direction of the combine. The first and second inclination sensors 135a and 135b are electrically connected to the control device 100. As a result, signals (information) regarding the tilt angle in the front-rear direction of the combine and the tilt angle in the combine width direction detected by the first and second tilt sensors 135a and 135b can be transmitted to the control device 100, respectively.

  Moreover, the combine 201 has the auger rest 52 which accommodates the horizontal discharge auger 15b in an accommodation position, as shown in FIG.1, FIG2 and FIG.4. The augerest 52 is a member that supports the horizontal discharge auger 15b of the grain discharge device 15 when the grain discharge device 15 is not used, and is configured in a substantially Y shape. The augerest sensor 54 for detecting the lateral discharge auger 15b is arranged. This sensor 54 is electrically connected to the control device 100. Thereby, a signal (information) as to whether or not the lateral discharge auger 15 b is placed on the placement portion of the auger rest 52 detected by the sensor 54 can be transmitted to the control device 100.

  Further, the combine 201 can be provided with one or more spirit levels at a position where the operator can visually recognize the work. FIG. 7 is a view of the driving operation unit in the cab 14 as seen from above. For example, as shown in FIG. 7, level levels 21 and 22 can be provided on the left and right of the driver's seat 14a on the left and right, respectively, with the steering handle 31 near the front column 30 as a reference. A level 23 can be provided in the vicinity of 40. A display device 24 is provided at the center of the steering handle 31 of the front column 30, a setting switch 25 is provided on the upper left side of the display device 24, and a display changeover switch 26 is provided on the lower left side of the display device 24. However, a harvest information switch 27 is further provided on the left side of the back of the driver's seat 14a, and both are electrically connected to the control device 100. Thereby, input signals (information) of the setting switch 25, the display changeover switch 26, and the harvest information switch 27 can be sent to the control device 100, and output information is transmitted from the control device 100 to the display device 24 and the printing device 39. can do. The display device 24 is an example of display means, and the setting switch 25, the display changeover switch 26, and the harvest information switch 27 are all examples of operation means that can be manually operated.

  Next, the configuration of the control system of the combine 201 according to the present embodiment will be described with reference to FIGS.

  FIG. 8 is a block diagram showing a schematic configuration of a control system of the combine 201 according to the present embodiment. As shown in FIG. 8, the combine 201 includes a control device 100 that controls the sensor device 50 in addition to the sensor device 50 including the weight sensor 32, the moisture sensor 35, the tilt sensor 135, and the augerest sensor 54 described above. I have. The control device 100 includes a central processing unit 101 (hereinafter referred to as a CPU) including control arithmetic means for executing arithmetic processing based on signals input from various sensors, switches, and the like, a control program for controlling the entire combine 201, and the like. Or a ROM 103 that stores predetermined data relating to an arithmetic expression, which will be described later, and a RAM 103 that temporarily holds data generated during the operation of the CPU 101. The CPU 101 is configured to load and execute a control program stored in the ROM 102 into the RAM 103 as necessary to operate the combine 201. The ROM 102 stores a predetermined factor for displaying an alarm described later. The CPU 101 has a built-in timer for a clock.

  The control program causes the CPU 101 to function as means including grain weight measuring means P1, grain weight correcting means P2, grain weight display means P3, grain weight printing means P4, and grain weight warning means P5.

  The grain weight measuring means P <b> 1 measures the grain weight value based on the information regarding the grain weight sent from the weight sensor 32. Specifically, the grain weight value is converted from the information on the grain weight from the weight sensor 32 using a predetermined grain weight conversion formula. In this example, the grain weight value is converted using an arithmetic expression for grain weight conversion, but may be converted using a corresponding LUT (lookup table). In the grain weight measuring means P1, the zero point setting of the weigh scale is performed to set the measured value from the weight sensor 32 to the zero point.

  In the grain weight correcting means P2, the grain weight value is corrected based on the information on the grain moisture sent from the moisture sensor 35, and / or the combine sent from the first and second inclination sensors 135a and 135b, respectively. The grain weight value is corrected based on information about the tilt angle in the front-rear direction and the tilt angle in the combine width direction. Specifically, the grain weight moisture correction value is converted from the information on the grain moisture from the moisture sensor 35 using a predetermined grain weight moisture correction conversion calculation formula, or / and the first and second inclination sensors 135a, The grain weight inclination correction value is converted from the information about the inclination angle in the longitudinal direction of the combine and the inclination angle in the combine width direction from 135b using a predetermined grain weight inclination correction conversion calculation formula. The grain weight moisture correction value and the grain weight inclination correction value are converted using a correction conversion arithmetic expression in this example, but may be converted using a corresponding LUT (lookup table).

  In the grain weight display means P3, the grain weight value related to the grain yield and / or the grain discharge amount of the weight sensor 32 is displayed on the display device 24 as an output value based on the measurement result of the weight sensor 32. The output value is the value of the weight sensor 32 when the measured value of the weight sensor 32 is corrected based on the measured value of the weight sensor 32 or the measured values of the first and second inclination sensors 135a and 135b or the moisture sensor 35. It is a correction value.

  In the grain weight printing means P4, as an output value based on the measurement result of the weight sensor 32, a grain weight value related to the grain yield and / or the grain discharge amount of the weight sensor 32 is connected to the control device 100. (See FIG. 8). The output value is the weight sensor 32 when the measured value of the weight sensor 32 is corrected based on the measured value of the weight sensor 32 or the measured values of the first and second inclination sensors 135a and 135b and the moisture sensor 35. Is the correction value.

  In the grain weight warning means P5, when the weight sensor 32 is activated in response to an artificial operation, it is determined that the machine body frame 2 is tilted by a predetermined amount or more based on the measured values from the first and second tilt sensors 135a and 135b. In this case, an alarm is issued to the operator, or the weight sensor 32 is operated in accordance with an artificial operation to display the grain weight value related to the grain yield and / or the grain discharge amount on the display device 24 by the means P3. When the grain weight value is out of the predetermined range when the information is displayed on the printing device 39 or printed out by the means P4, an alarm is displayed in addition to the grain weight value. Specifically, the weight sensor 32 is actuated in response to an artificial operation via the setting switch 25, the display changeover switch 26, the harvest information switch 27, etc., and the grain weight value relating to the grain yield and / or the grain discharge amount is obtained. When the measured values of the first and second inclination sensors 135a and 135b or the moisture sensor 35 are outside the predetermined ranges when displayed by the means P3 or printed out by the means P4 (in this example, When the measured value of the weight sensor 32 exceeds a predetermined correction limit value), an alarm is displayed in addition to the grain weight value. In this example, this alarm display is an indication that there is a possibility that the error is large with respect to the grain weight value. As described above, the predetermined factor for the alarm display is stored in the ROM 102. By reading the alarm display factor from the ROM 102, the factor is clearly indicated in the alarm display. By the way, in the means P1, the zero point of the weighing scale is sometimes set. However, when the body frame 2 is inclined, if the zero point setting of the weighing scale is performed, the measurement accuracy is likely to be lowered accordingly. Therefore, in the means P5, when the zero point setting of the weighing scale is performed, the inclination value of the body frame 2 is outside the predetermined zero point setting inclination range based on the measured values from the first and second inclination sensors 135a and 135b. Alarm to the operator or / and prohibit zeroing of the weigh scale.

  Note that the cause of the alarm display (in other words, the cause of the error in the grain weight value) is, in this example, the crop yield when the grain is stored in the Glen tank 13, and the grain is removed from the Glen tank 13. The maximum amount of grain discharged during the discharge, the maximum inclination angle of the fuselage frame 2, and the maximum amount of grain moisture (for example, the amount of grain contained and the amount of water adhering to the surface with much moisture). In this example, the measured values when the alarm is displayed are the minimum values of the grain yield and the amount of grain discharged, both of which are 200 kg or less, and the machine body frame 2 is horizontal with respect to the maximum value of the tilt angle. When the value is 0 °, the tilt in the longitudinal direction of the combine (absolute value) is 10 ° or more, the tilt in the combine width direction (absolute value) is 5 ° or more, and the maximum value of the moisture content is 35% or more. The value is less than 40%, and the maximum value of the surface adhering water amount is 40% or more. Further, in the present example, the zero point setting inclination range is set to ± 5 ° with 0 ° when the body frame is horizontal.

  FIG. 9 is a diagram showing a display screen during the harvesting operation of the display device 24, and FIG. 10 is a diagram showing print contents during the harvesting operation printed by the printing device 39.

  During the harvesting operation, the horizontal discharge auger 15 b is placed on the placement portion of the auger rest 52. At this time, it is detected by the augerrest sensor 54 that the lateral discharge auger 15b is placed on the placement portion of the augerest 52. In this state, when the harvest information switch 27 is pressed and the switch 27 is in the ON state, the weight sensor 32 detects information regarding the grain weight, and the information is sent to the control device 100, and the moisture sensor 35 and The first and second tilt sensors 135a and 135b send information on the grain moisture and information on the tilt angle in the front and rear direction of the combine and the tilt angle in the combine width direction to the control device 100, respectively.

  In the control device 100, the control program is executed, and the CPU 101 functions as each of the means P1 to P5. That is, the grain weight is measured by converting the information on the grain weight sent from the weight sensor 32 into a grain weight value using the predetermined grain weight conversion formula in the means P1. At this time, depending on the information on the grain moisture sent from the moisture sensor 35, the information is converted into the grain weight moisture correction value by using a predetermined grain weight moisture correction conversion calculation formula in the means P2. Further, depending on the information about the tilt angle in the front and rear direction of the combine and the tilt angle in the combine width direction sent from the first and second tilt sensors 135a and 135b, the calculation for predetermined grain weight tilt correction conversion is performed by means P2 from the information. The grain weight may be corrected by converting into a grain weight inclination correction value using an equation. The grain weight value obtained in this way is stored in the RAM 103 together with the grain moisture content based on the grain moisture information and the tilt angle based on the tilt angle information.

  On the other hand, the “normal screen” is displayed on the display screen of the display device 24 as shown in the screen A in FIG. 9. When the setting switch 25 is pressed here, the “normal screen” starts. 9, the screen shifts to a “working harvest information display screen” as shown on the screen B in FIG. 9, and the grain weight (in operation) relating to the grain yield based on the measurement result of the weight sensor 32 by means P3 on this screen. The amount of grain moisture in operation related to the grain yield based on the mass) value and the measurement result of the moisture sensor 35 is displayed. Note that this display is updated as needed every predetermined time (for example, every 2 seconds).

  Thus, the grain weight value related to the grain yield is displayed. At this time, if the measured value of the weight sensor 32 exceeds the predetermined correction limit value in the means P5, the grain weight value is displayed. In addition, an alarm display is made to the effect that there is a possibility of a large error in the grain weight value. Then, by reading the factor of the alarm display from the ROM 102, the factor is clearly shown in the alarm display.

  Specifically, at a predetermined location G on the display screen B, when the crop yield is 200 kg or less, it is clearly indicated that the crop yield is extremely small, and the tilt based on the information on the tilt angle. When the angle is 10 ° or more in the tilt in the front and rear direction of the combine (absolute value) or 5 ° or more in the tilt in the combine width direction (absolute value), it is clearly stated that the maximum of the tilt angle is a factor. When the grain moisture amount based on the information on the grain moisture is 35% or more and less than 40%, the maximum of the contained moisture amount is a factor. It is clearly stated that the local maximum is the factor. When “Return” Q1 is selected on the screen B in FIG. 9, the screen returns to the “normal screen” on the screen A in FIG. 9, and when the setting switch 25 is pressed again, the “work in progress” on the screen B in FIG. Move to “Crop Information Display Screen”.

  Further, during the harvesting operation or after the harvesting operation is finished, when the grain in the grain tank 13 storing the grain is discharged by the discharge device 15, the lateral discharge auger 15 b is rotated and the auger rest 52 is mounted. Separated from the placement part (storage position). At this time, it is detected by the augerrest sensor 54 that the lateral discharge auger 15b is not placed on the placement portion of the augerest 52. In this state, when the cereal is discharged by the discharge device 15, information on the cereal weight is detected by the weight sensor 32, and the discharged cereal weight is determined based on the information on the cereal weight sent from the weight sensor 32. Measured at At this time, the grain moisture stored during the harvesting operation is averaged in advance, and based on this grain average moisture, before and after the combine sent from the first and second inclination sensors 135a and 135b, respectively. The grain weight may be corrected based on information about the tilt angle in the direction and the tilt angle in the combine width direction. The grain weight thus obtained is stored in the RAM 103 together with the grain average moisture content and the tilt angle based on the information on the tilt angle. The grain discharge value is obtained by calculating the difference between the grain weight value before being discharged from the Glen tank 13 and the grain weight value after being discharged from the Glen tank 13.

  After the grain is discharged from the grain tank 13, when the horizontal discharge auger 15b is stored again in the storage position, the grain weight value, grain average moisture content and inclination angle discharged here are read from the RAM 103 and read. The grain weight (mass) value and grain average water content are displayed on the “Crop Information Display Screen for Ejected Grain” as shown in the screen C in FIG. Also in the “harvested grain harvest information display screen (screen C in FIG. 9)”, the measured value of the weight sensor 32 is determined in a predetermined manner, similar to the “working harvest information display screen (screen B in FIG. 9)”. When the correction limit value is exceeded, in addition to the grain weight value, an alarm is displayed to the effect that there is a possibility that the error is large for the grain weight value. Specifically, in a predetermined location G on the display screen C, when the grain discharge amount is 200 kg or less, it is clearly stated that the grain discharge amount is the minimum, and the tilt angle is determined in the longitudinal direction of the combine. When the slope (absolute value) is 10 ° or more or the slope in the combine width direction (absolute value) is 5 ° or more, it is clearly stated that the maximum of the inclination angle is a factor, and the average grain moisture content In the case of 35% or more and less than 40%, it is clearly stated that the maximum of the moisture content is a factor, and in the case of 40% or more, the maximum of the surface adhering water amount is a factor. . The grain discharge amount, the alarm display, and the factors thereof thus obtained are stored in the RAM 103.

  When “Switch” Q2 is selected on the C screen in FIG. 9, the grain discharge amount, grain average moisture amount, inclination angle, alarm display, and its factor are read from the RAM 103 for the grain discharged in the past in this harvesting operation. The grain weight (mass) value obtained by accumulating the read grain discharge amount and the grain average moisture amount are displayed on the “accumulated harvest information display screen of the discharged grain” as shown in the screen D in FIG. . When “switch” Q2 is selected in this state, the screen returns to the “emerged grain harvest information display screen (screen C in FIG. 9)” again. In addition, on the “cumulative harvest information display screen (D screen in FIG. 9)” of this “exhausted cereal”, the alarm display read from the RAM 103 and its factor are clearly shown at a predetermined location G on the display screen D.

  In addition, when “print” Q3 is selected in the “emergency harvest information display screen (C screen in FIG. 9)” and “accumulated harvest information display screen (D screen in FIG. 9)”, FIG. In the case of the middle C screen, as shown on the left side in FIG. 10, the printing content of the harvest information of the A discharged cereal is printed on the recording paper by the printing device 39, and at a predetermined position G on the recording paper, When there is an alarm display, the alarm display and its factor are printed. In the case of the D screen in FIG. 9, printing of the cumulative harvest information of the B discharged cereal is performed by the printer 39 as shown on the right side of FIG. The contents are printed on the recording paper, and when there is an alarm display at a predetermined location G on the recording paper, the alarm display and its factor are printed. In addition, when “return” Q1 is selected in both of the “exhaust grain harvest information display screen (screen C in FIG. 9)” and the “exhaust grain cumulative harvest information display screen (screen D in FIG. 9)”. Return to the “normal screen (screen A in FIG. 9)” or “working harvest information display screen (screen B in FIG. 9)”.

  FIG. 11 is a diagram illustrating a display screen after the harvesting operation is completed on the display device 24, and FIG. 12 is a diagram illustrating print contents of the harvest information of the one-stroke farm field printed by the printing device 39.

  When the harvesting operation is finished and the “normal screen at the end of the operation (A screen in FIG. 11)” or “the harvest information display screen at the end of the operation (B screen in FIG. 11)” is displayed, the harvest information switch When the switch 27 is pressed for a predetermined time and the switch 27 is turned off, the information stored in the RAM 103 is read out, and the read out information is added up to calculate “total of one field work”. In “Crop information display screen (C screen or D screen in FIG. 11)”, the total weight (mass), yield, and working time are shown on the C screen in FIG. 11, and the average moisture, maximum moisture, and minimum are shown on the D screen in FIG. Each moisture is displayed. Note that the C screen and the D screen in FIG. 11 are switched to each other by selecting “switch” Q2 in each screen, and are ended by selecting “end” Q4.

  Furthermore, when “print” Q3 is selected on the C screen or the D screen in FIG. 11, the printing content of the harvest information of the one-stroke field is printed on the recording paper by the printing device 39 as shown in FIG. When there is an alarm display at a predetermined location G on the recording paper, the alarm display and its factor are printed.

  In this example, an alarm is given by displaying character information, but an alarm may be given by, for example, a warning light, a buzzer, a voice output means, or the like. In this way, the operator can be further alerted.

  By the way, in this combine 201, the zero point setting of the weighing scale for setting the measured value from the weight sensor 32 to the zero point can be performed by the means P1, and this will be described below with reference to FIG. .

  When the zero point setting of the weigh scale is performed, first, “Weigh scale zero point adjustment” shown on the screen A in FIG. 13 is selected to enter the zero scale setting mode of the weigh scale. Next, when the inclination of the fuselage frame 2 of the combine 201 is detected by the first and second inclination sensors 135a and 135b and the detected inclination is outside the zero point setting inclination range (± 5 ° in this example). , A message shown on screen B in FIG. 13 is displayed, and zero setting of the weigh scale is prohibited. On the other hand, when the detected inclination is within the zero point setting inclination range, the message shown in screen C in FIG. 13 is displayed, and when “execute” is selected in the screen, zero setting of the weigh scale is executed. Then, the message shown on screen D in FIG. 13 is displayed.

  According to the combine 201 described above, when the weight sensor 32 is activated in response to an artificial operation via the setting switch 25, the display changeover switch 26, the harvest information switch 27, and the like, based on the measurement values from the inclination sensors 135a and 135b. When it is determined that the fuselage frame 2 is tilted more than a predetermined value (in this example, when the measured value of the weight sensor 32 is determined to exceed a predetermined correction limit value), an alarm is issued to the operator. When measuring the weight of the grain in the tank 13, it is possible to inform the operator whether or not the machine body frame 2 is tilted too much, so that the operator moves the combine to a flat place and the weight of the grain. (For example, by measuring the body frame 2 as horizontal as possible within a predetermined allowable tilt angle range) Correspondingly it is possible to obtain a highly accurate measurement.

  In addition, when it is determined that the body frame 2 is inclined more than a predetermined value (in this example, when it is determined that the measured value of the weight sensor 32 exceeds a predetermined correction limit value), the grain weight is unavoidably measured. Even in this case, since alarm display is performed on the display device 24 in addition to the output value, it is possible to easily distinguish an output value in which the error exceeds an allowable range from an output value and an output value that is not.

  Furthermore, in this combine 201, since the zero point of the weighing scale is set, for example, at the time of factory shipment, maintenance, or prior to measuring the grain weight in the grain tank 13, the grain tank 13 is empty. The measured value from the weight sensor 32 can be set to the zero point in advance. Further, when setting the zero point of the weighing scale, an alarm is issued to the operator when the inclination value of the body frame 2 is outside the predetermined zero point setting inclination range based on the measurement values from the inclination sensors 135a and 135b. At the same time, the zero point setting of the weigh scale is prohibited, so that the measurement accuracy can be prevented from being lowered and the reliability of the measurement value can be improved.

  In the combine 201, the level levels 21 to 23 that allow the operator to know the tilted state of the machine body frame 2 are provided at a position that can be visually recognized during work. Therefore, when collecting the harvest information data, At any time, the level of the body frame 2 can be confirmed using the level 21 to 23, and the operator can work with peace of mind.
