  Next, the structure of each part of the grain discharging apparatus 15 and its operation means will be described with reference to FIGS. 2, 5, and 6.

  As shown in FIG. 5, in the grain discharging apparatus 15, the base side of the horizontal discharge auger 15b is pivotally attached to the upper end of the vertical discharge 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.

  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 in order to pivotally support the transverse feed conveyor 117. 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 grains 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 auger rest 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. As shown in FIG. 1 and FIG. 4, the auger rest 52 is formed in a substantially Y shape, and a sensor 54 for detecting the lateral discharge auger 15 b is arranged in the concave portion of the upper mounting portion and connected to the control means 53. Has been. Thus, when it is detected that the horizontal discharge auger 15b is placed on the placement portion of the auger rest 52, the weight tank 32 measures the weight of the glen tank, and the grain weight, moisture, etc. during the cutting operation are measured. , Stored in the storage unit 55. Further, when the sensor 54 detects that the lateral discharge auger 15b is not in the placing portion, the weight when discharged by the discharge device 15 is measured. Further, the measured grain tank weight, grain moisture, and the like can be printed on a recording sheet by the printing device 39 connected to the control means 53 or displayed on the display device 42. Further, the obtained grain weight can be stored in the storage unit 55, and the grain weight at an arbitrary time such as after the harvesting operation can be printed by the printing device 39 or displayed on the display device 42.

  As shown in FIGS. 12, 13, and 14, the weight sensor 32 is disposed below the front of the glen tank 13, and the weight sensor 32 is a U-shaped bracket 24 in a side view for protection. It is fixed on the fuselage frame 2 via. A spacer 25 is placed and fixed on the upper part of the detection part of the weight sensor 32 according to the size, and a protector 26 is fixed on the upper part of the spacer 25. The protector 26 has a substantially inverted U shape when viewed from the side, extends in the horizontal direction in the direction of travel, and is positioned substantially below the center of the left and right width of the glen tank 13. A pair of front and rear pieces projecting downward from the front and rear of the protector 26 are located outside the bracket 24 so as to cover the entire weight sensor 32, and are provided between the inner side of the protector 26 and the outer side of the bracket 24. It is arranged so as to be fitted with a gap, and the load applied on the protector 26 can be detected by the detection unit of the weight sensor 32 by restricting the movement in the front-rear direction and covers the upper side and the side of the weight sensor 32. To protect it.

  On the other hand, in the front lower part of the Glen tank frame 27 that supports the Glen tank 13 on the side facing the weight sensor 32, the bottom plate is placed on the front bottom surface of the Glen tank 13 at the lower part of the Glen tank frame 27 arranged in the left-right direction with respect to the traveling direction. A mounting plate 29 is fixed via 28, and a round bar-shaped contact body 30 is fixed to the lower surface of the mounting plate 29. The contact body 30 extends in a substantially tangential direction (left and right horizontal direction) with respect to the vertical rotation axis of the Glen tank 13 (the axis of the vertical discharge auger 15a). Then, the left and right sides of the contact body 30 are folded diagonally upward into a “<” shape so that the Glen tank 13 is opened outward or returned to the original position so that it can be smoothly ridden on the body frame 2. I have to. In this way, the contact body 30 has a simple structure and can be easily manufactured at low cost. However, the contact body 30 is not limited to a round bar, and may be formed of a polygonal shape such as a triangle in cross section or a bar material such as a semicircle if the lower surface is linear.

  And it is comprised so that the left-right center part may be horizontal and may contact with the protector 26 on the weight sensor 32 by a line. That is, the detection part of the weight sensor 32 arranged at the lower part of the front and rear other side (front side) with the front and rear one side (rear side) of the Glen tank 13 as a fulcrum is in contact with the linear contact point, and the change of the front and rear support points is changed. Almost no weight measurement with high accuracy is possible. Specifically, as shown in FIG. 10, in order to measure the weight of the Glen tank 13, the vertical discharge auger 15a serving as a fulcrum at the lower part on one side in the front-and-rear direction is used as a fulcrum A, and the weight is arranged at the front part on the other side The supporting part of the sensor 32 is a fulcrum B, and the weight of the grain in the Glen tank 13 is detected by measuring the load at the fulcrum B. When the belt-like or rectangular parallelepiped contact body 31 is disposed on the upper surface of the weight sensor 32 at the fulcrum B and is in contact with the surface, contact is made at the rear end of the contact body 31 due to rattling of the Glen tank 13 or the like. (The distance from the center of gravity G is B1) and the case of contact at the front end of the contact body 31 (the distance from the center of gravity G is B2), and the weight is the difference between the distances from the center of gravity (B2-B1). Changes may occur and accurate weight measurement may not be possible. In the present embodiment, since the contact is made with a line, the distance from the center of gravity G does not change even if there is a wrinkle, and the weight can be accurately measured.

  In this way, the weight of the grain tank 13 is measured by the weight sensor 32, and the grain is put into the grain tank 13 by the cereal conveyor 23 that communicates with the first conveyor. Is connected to the most conveyor, and a spout 23a is provided at the upper end to communicate with the rear part of the Glen tank 13. A discharge conveyor 16 is disposed in the front-rear direction below the grain tank 13, and the rear part communicates with the vertical discharge auger 15a so that the grains in the grain tank 13 can be discharged from the rear part.

  Thus, when the spout 23a is provided on the rear part of the Glen tank 13 and discharged from the rear part of the discharge conveyor 16 provided in the front-rear direction, the output of the weight sensor 32 and the true weight of the input grain As shown in FIG. 9A, the calibration curve is a substantially elliptical curve having a main curve M1 curved upward and curved to the right and a main curve M2 curved downward to the left. Further, when the spout 23a is provided on the front part of the Glen tank 13 and discharged from the front part of the discharge conveyor 16 provided in the front-rear direction, the result is as shown in FIG. 9B. Furthermore, when the operation is completed while the Glen tank 13 is not full, the calibration curve at the time of charging is the same, but the calibration curve at the time of discharge is the dotted line C1 or the alternate long and short dash line C2 in FIG. Thus, the emission calibration curve decreases from the middle of the input calibration curve. The calibration curve discharged from the middle position is a curve that curves upward and converges to the main curve M2 to be discharged. On the contrary, it may be discharged halfway, interrupted, and re-cutted and thrown in again. The calibration curve input from the middle position becomes a curve D1 that curves downward and rises, and converges to the main curve M1 to be input. Therefore, the estimated grain weight obtained by calculating the detected value corresponding to the calibration curve is a substantially accurate grain weight.

  As described above, the relationship between the output of the weight sensor 32 and the weight of the input grain is not directly proportional, and is disposed at the position of the spout, for example, at the rear or front, the front / rear midway, right or left. In this case, the shape of the calibration curve differs depending on the discharge position of the discharge conveyor, for example, the front / rear or left / right arrangement positions. Therefore, in the present invention, in the Glen tank 13 in which the position of the spout and the discharge position of the discharge conveyor are determined in advance, the weight sensor at the time of charging and discharging (including the case of discharging in the middle without being full) A calibration curve indicating the relationship between the output of 32 and the true weight of the input grain is stored in the storage unit 55 as a map, and a detection signal from the weight sensor 32 is input to the control means 53 during a harvesting operation. Then, the detected value is calculated from the calibration curve, converted to a value close to the true grain weight, and the estimated grain weight after calculation corresponding to the map is output from the control means 53. Similarly, at the time of discharging, an estimated grain weight having a value close to the true grain weight is calculated from the detection value of the weight sensor 32 by the control means 53 from the calibration curve. Further, when discharging from the middle when the tank does not become full, it gradually decreases from the calibration curve M1 and converges to the calibration curve M2. It gradually increases from the line M2 and converges to the calibration curve M1. In the control means 53, the judgment at the time of harvesting and discharging is made by the sensor 54 provided on the auger rest on which the horizontal discharging auger is placed. Yes, when the horizontal discharge auger is not located on the auger rest, it can be determined that it is during discharging, but it can also be determined by ON / OFF of the auger clutch or the like of the grain discharging device 15.

  Moreover, the shape of the calibration curve differs depending on the type of grain. For example, rice and wheat have different bulk densities (specific gravity), and wheat has a larger bulk density. Therefore, as shown by calibration curve E in FIG. Therefore, in the present invention, the control means 53 is connected to a correction means 57 having a correction value in accordance with the grain type, and the correction means is switched by the switching means 58 according to the grain type. Thus, the correct weight can be obtained by performing the work by switching the correction means 57 according to the type of grain before the work.
