(Weight detector)
The combine is provided with a weight detection unit 6 on the body frame 1 for measuring the weight of the grains stored in the Glen tank 5.
As shown in FIGS. 3 to 7, the weight detection unit 6 has a load cell 60 (corresponding to a yield sensor) for measuring the weight of the grains stored in the grain tank 5. The body frame 1 is provided so that the weight of the tank 5 can be received and the weight can be measured.
The weight detector 6 is provided with a vertical frame 12 (corresponding to the main frame) and a pedestal bracket 13 as a mounting structure for mounting the load cell 60 on the body frame 1, and the load cell 60. A movable guide member 70 (corresponding to a guide member) is provided to guide the pressure receiving surface 63A so that the weight on the Glen tank 5 side acts. Further, the glen tank 5 is provided with a support leg 80 for loading the load cell 60 with its weight, and a guide leg 90 for smoothly swinging the glen tank 5 on the body frame 1. It is done.

The position on the machine body frame 1 where the load cell 60 is disposed is a position corresponding to a position below the bottom of the Glen tank 5 located at the working posture position, and a support provided on the lower side of the Glen tank 5. This is the position where the weight of the Glen tank 5 acts via the leg 80. That is, as shown in FIGS. 3 and 4, the position where the load cell 60 is disposed on the body frame 1 is close to the center of gravity G of the Glen tank 5 located at the work posture position in the left-right direction. It has been established.
Specifically, a virtual vertical plane yF in the front-rear direction passing through the center of the load cell 60 at the same position as or near the centroid of the projected view of the Glen tank 5 in a state of being located at the work posture position (FIG. 3).

As shown in FIG. 4, in the plan view, the load cell 60 is located far from the vertical axis y <b> 1 that is the swing fulcrum of the Glen tank 5 and in the working posture position. Since this is near the front end of this, an improvement in detection accuracy can also be expected in this respect. That is, if the position of the load cell 60 is far from the vertical axis y1 that is the swing fulcrum of the Glen tank 5, the part of the Glen tank 5 corresponding to the load cell 60 is necessarily far from the vertical axis y1. The amount of deformation of the Glen tank 5 itself due to the grain weight tends to be relatively large at the position corresponding to the load cell 60.
Therefore, for example, when the load cell 60 is located near the rocking fulcrum of the Glen tank 5 and the amount of bending deformation due to the weight of the Glen tank 5 itself tends to be extremely small, the Glen tank 5 itself The load cell 60 can easily detect the weight of the Glen tank 5 using the tendency that the ratio of the deformation amount per weight increases.
