The grains obtained by the threshing device 11 are carried to the grain tank 12 via the winnowing device 14 and stored in the grain tank 12.

(grain tank and grain discharge device)

As shown in fig. 3, the grain tank 12 is raised and lowered around a horizontal axis P, and specifically, the grain tank 12 is raised and lowered through a rotation locus T (see fig. 2) of the grain discharging device 40. A grain outlet (not shown) is formed on the right lateral side of the grain tank 12, and when the grain tank 12 is in the raised position, the grains stored in the grain tank 12 are discharged outside the machine body.

The grain discharging device 40 is composed of a vertical conveying part 41 and a horizontal conveying part 45 extending in the horizontal direction from the upper end of the vertical conveying part 41, is connected to a lower part of the grain box 12, is at a low position when the grain box 12 is lifted, and is rotated about a vertical axis Y (see fig. 2) to discharge the grains stored in the grain box 12 to the outside of the machine body.

That is, in the present embodiment, the grain stored in the grain tank 12 may be discharged to the outside of the machine body by the grain discharging device 40 or by a grain discharging port (not shown) of the grain tank 12.

(operating parts)

As shown in fig. 1 and 2, the remote controller 8 is removably placed in a sheath body mounted on the rear wall of the cab 70. As shown in fig. 4, a rectangular operation surface 80 is formed on the surface of the remote controller 8, and a cross key 81 as a manual button is disposed in a substantially central portion of the operation surface 80. The vertical first piece 82 (corresponding to a first operation element) of the cross key 81 serves as a lifting operation unit UD for operating the lifting of the grain tank 12, and the horizontal second piece 83 (corresponding to a second operation element) of the cross key 81 serves as a rotation operation unit LR for operating the rotation of the grain discharging device 40.

Pressing the upper end 82U of the first sheet 82 can instruct the grain tank 12 to ascend, and pressing the lower end 82D of the first sheet 82 can instruct the grain tank 12 to descend. Further, by pressing the left end portion 83L of the second piece 83, it is possible to instruct the grain discharging device 40 to rotate leftward (rotate counterclockwise), that is, to instruct the grain discharging device 40 to unfold to the use position, and by pressing the right end portion 83R of the second piece 83, it is possible to instruct the grain discharging device 40 to rotate rightward (rotate clockwise), that is, to instruct the grain discharging device 40 to store.

In addition, an automatic button 84 (corresponding to a third operation element) for operating both the grain tank 12 and the grain discharge device 40 is disposed in an upper region of the operation surface 80, i.e., above the cross key 81. Specifically, the automatic button 84 is used to instruct the lowering of the grain tank 12 and the storage of the grain discharging device 40.

(interference preventing part)

As shown in fig. 4, the combine harvester further includes an interference preventing unit 5, and when the automatic button 84 is operated, the interference preventing unit 5 operates the grain tank 12 and the grain discharging device 40 so that the lowering of the grain tank 12 and the storage of the grain discharging device 40 do not interfere with each other. Specifically, as shown in fig. 5, the interference preventing unit 5 operates the grain tank 12 and the grain discharging device 40 so that the grain discharging device 40 starts to store the grain from the time when the grain tank 12 is lowered to a position in the middle of the lowering operation.

(other embodiments)

(1) In another embodiment, the auto button 84 may be used to instruct not only the lowering of the grain tank 12 and the storage of the grain discharging device 40, but also the raising of the grain tank 12 and the deployment of the grain discharging device 40 to the use position.

At this time, the automatic button 84 selects whether to raise the grain tank 12 and unfold the grain discharge device 40 to the use position, or to lower the grain tank 12 and store the grain discharge device 40, depending on the postures of the grain tank 12 and the grain discharge device 40. For example, when the grain tank 12 is in the lowered position and the grain discharge device 40 is in the storage position, the automatic button 84 selects to raise the grain tank 12 and to unfold the grain discharge device 40 to the use position. When the grain tank 12 is in the raised position and the grain discharge device 40 is in the deployed position, the automatic button 84 selects the lowering of the grain tank 12 and the storage of the grain discharge device 40.

When the automatic button 84 is operated, the interference preventing unit 5 operates the grain box 12 and the grain discharging device 40 so that the lifting of the grain box 12 and the spreading of the grain discharging device 40 to the use position do not interfere with each other. Specifically, as shown in fig. 6, the interference preventing unit 5 operates the grain discharging device 40 and the grain box 12 such that the grain box 12 starts to rise from the time when the grain discharging device 40 rotates to a position in the middle of the unfolding operation.

The interference preventing unit 5 may be configured to operate the grain tank 12 and the grain discharging device 40 so that the lowering of the grain tank 12 and the storage of the grain discharging device 40 do not interfere with each other when the automatic button 84 is operated (see fig. 5).
