Thereby, the tip side of the cereal is transported into the threshing unit 12, and the threshing of the cereal is performed in the threshing unit 12.

  A waste chain 18 is disposed at the rear end of the feed chain 9, and a waste processing unit 19 including a waste cutter device, a diffusion conveyor, and the like is disposed below the rear portion of the waste chain 18. 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 of 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. The other end is pivotally attached to a bracket 132 protruding from the side surface of the horizontal discharge auger 15b. 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.

  More specifically, on the upper part of the vertical discharge auger 15a and the rear part of the grain tank 13, a later-described allowance part 59 (see FIG. 6) and a rotating grain tank fixing mechanism 60 are provided. 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. Thus, when the Glen tank 13 is rotated to the side for maintenance or the like, the allowance of the allowance portion 59 is canceled 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 for connecting the wire 64, and the wire receiver 69 is integrally provided on the outer surface of the open side end portion of the guide plate 61. In addition to supporting, 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 and an augerest sensor 54 in addition to the weight sensor 32 described above.

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 the moisture content 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) related to the moisture content of the grain, and is electrically connected to the control device 100 via a controller C21. Thereby, a signal (information) related to the amount of moisture detected by the moisture sensor 35 can be transmitted to the control device 100.

If there is, information on grain weight is detected by the weight sensor 32 in the means P1, information on grain moisture is detected by the moisture sensor 35, and these information are sent to the control device 100.

  Information on the grain weight and the grain moisture amount sent from the weight sensor 32 and the moisture sensor 35 is obtained by using the weight conversion formula and the moisture conversion formula for each predetermined measurement section. By converting each into a moisture content, the harvest weight and the grain moisture content are respectively measured, and the measured grain weight and the grain moisture content are stored in the RAM 103 as needed for each section. Further, in this means P1, the time integral value of the rack position that is displaced in time when the fuel injection amount of the fuel injection pump 45 is determined is calculated using the fuel consumption conversion arithmetic expression for each predetermined measurement section. By converting to the consumption amount, the fuel consumption amount is measured, and the measured fuel consumption amount is stored in the RAM 103 as needed. Further, other harvest information is also calculated here and stored in the RAM 103.

  Then, the harvested weight, grain moisture content, and the like stored in the RAM 103 are totaled under the first to third output conditions stored in advance in the ROM 102 in the means P2. That is, (1) In the first output condition, the total weight of the grain, the maximum moisture content, the minimum moisture content, the harvested area, the estimated mass when the moisture is 15%, the moisture content distribution, the work time, Fuel consumption, etc. are tabulated. (2) Under the second output condition, the total weight, average moisture content, maximum moisture content, minimum moisture content, harvest area, and 15% moisture estimated for each grain discharge operation The cumulative total of mass, moisture distribution, working time, fuel consumption, etc. is totaled. (3) Under the third output condition, the harvest area harvested by the combine 201 from the start of the harvest of the combine 201 is obtained from the GPS device 200. The total weight of the grain of the one-stroke field set as harvest information until the time when it matches the area of the one-stroke field according to GPS data, or the harvest information from the ON operation to the OFF operation of the predetermined switch by human operation, 10a hit The total yield of the average water content, maximum water content, minimum water content, harvested area, moisture 15% when estimated mass, water content distribution, working time, fuel consumption and the like are aggregated. The totaling results thus totaled are stored in the RAM 103 in the means P3.
