According to this, the information of the electronic tag 45 can be obtained by the receiving unit 20a only by bringing the discharge auger 8 closer to the container 40 after the grain is mowed by the mowing unit 6. Therefore, it is possible to easily grasp which container 40 the grain has been discharged. Further, since the eaves portion 81 is provided, even when light such as the sun is incident on the reading device 20, the eaves portion 81 can prevent light from entering the periphery of the lamp 60, and the lamp 60 is turned on. It is possible to easily grasp the state of the lamp 60 such as whether it is on or off.

The discharge auger 8 is rotatably supported by the machine body 2 between a storage position J10 having a tip portion located within the width of the machine body 2 and a discharge position J11 having a tip portion positioned outside the width of the machine body 2, and a casing. The body 21 has a facing wall where the discharge auger 8 faces the driver seat 4 at the storage position J10, and the lamp 60 is provided on the facing wall of the housing 21. According to this, the operating state of the receiving unit 20a can be easily confirmed from the driver's seat 4. That is, when the discharge auger 8 is at the storage position J10, the operating state of the receiving unit 20a can be confirmed by visually recognizing the lamp 60 provided on the facing wall from the driver's seat 4. Further, as shown in FIGS. 9 and 10, since the discharge auger 8 rotates about the turning axis O1 provided at the rear of the driver's seat 4, the discharge auger 8 faces the discharge position J11 even when the discharge auger 8 is at the discharge position J11. Since the wall faces the driver's seat 4 side, the operating state of the receiver 20a can be confirmed from the driver's seat 4 side even at the discharge position J11.

The discharge auger 8 includes a leading side that is rotated first and a trailing side that is rotated backward when the discharge auger 8 is rotated from the storage position J10 to the discharge position J11. The device 20 is attached to the trailing side of the discharge auger 8. According to this, since the reading device 20 is provided on the rear side of the discharging auger 8, when the discharging auger 8 is rotated from the storage position J10 to the discharging position J11, the reading device 20 causes an object outside the machine body 2 or the like. Can be suppressed.

In the above-described embodiment, the mounting bracket 23 and the eaves portion 81 are integrally formed, but the mounting bracket 23 and the eaves portion 81 may be separately configured. For example, the upper eaves portion 81a may be attached to the first plate 71 having the upper wall portion 71A, or the lower eaves portion 81b may be attached.
The embodiments disclosed this time are to be considered as illustrative in all points and not restrictive. The scope of the present invention is shown not by the above description but by the scope of the claims, and is intended to include meanings equivalent to the scope of the claims and all modifications within the scope. In the above-described embodiment, the container 40 is formed of a rectangular parallelepiped container, but may be formed of a cylindrical flexible container. The communication device 51 of the reading device 20 may wirelessly transmit the container information obtained from the electronic tag 45 from the discharge auger 8 to the machine body 2 side of the harvester 1.
