  The fuel container stand 18 of the present invention is mainly composed of a simple shaft-like member, and in addition, the side of the fuel container stand 18 is covered with the opening / closing cover 12, There is no loss of appearance.

  Next, a second embodiment of the present invention will be described with reference to an enlarged perspective view of the main part of FIG. 6 and an operation explanatory diagram of the main part of FIG.

  In this example as well, most of the configuration is the same as that of the first embodiment, but the clamp as a stopper when the mounting portion 23 is held in the vertical direction in the storage state of the fuel container stand 18. 28, the opening portion is directed to the side of the traveling machine body 1, and the protrusion 29 formed by the stopper pin at the tip of the support portion 20 protrudes only on the mounting portion 23 standing side of the fuel container stand 18. And the point that a right rotation stopper 17d is provided on the opposite side of the receiving portion 17a.

  Therefore, according to this example, the placement portion 23 is pulled out in the direction of arrow A (arrow G), the placement portion 23 is released from the locking of the clamp 28, and the protrusion 29 at the tip of the support portion 20 is located behind the support member 17. If it is pulled out until it comes into contact with the side wall 17c, and then rotated in the direction of arrow E in FIG. 7, the fuel container mounting base 18 is placed in the mounting state of the fuel container 22 with its mounting portion 23 facing in the horizontal direction. At this time, the protrusion 29 at the tip of the support portion 20 contacts the receiving portion 17a of the support member 17 to form the contact portion 27, and maintains a horizontal posture in which it does not rotate any more.

  In the first and second embodiments, the case where the support member 17 is mounted on the motor base 19 has been described. However, since the support member 17 and the fuel mount 18 are small and simple in configuration, this is not necessarily the case. It is not limited to this, and it may be installed at another position adjacent to the fuel filler opening 9.

  Next, the operation of the present invention will be described. With the above-described configuration, first, at the time of airframe inspection before starting the harvesting and harvesting operation, and when the operator starts the engine 8 to drive each drive unit of the traveling airframe 1. During the harvesting and harvesting work, it is necessary to supply fuel.

  At that time, with the engine 8 stopped, first, the opening / closing cover 12 is opened, and the substantially circular mounting portion 23 of the fuel container mounting base 18 is gripped, and the direction of arrow C in FIG. Is turned, and the holding portion 23 and the clamp 25 are unlocked, and then pulled toward the front in the direction of the arrow A, before the projection 21 contacts the end portion 19a of the motor base 19. When the projection 21 at the tip of the support portion 20 is pulled out until it contacts the rear side wall 17c of the support member 17, the one side of the projection 21 contacts with the receiving portion 17a. The portion 27 is formed, and the fuel container mounting base 18 is positioned in a horizontal state.

  Therefore, as shown in FIG. 5, the fuel container 22 is mounted on the mounting portion 23 and the cap 9a of the fuel filler port 9 is removed, and the fuel in the fuel container 22 is used using a separate pump (not shown). Then, replenishment is made from the fuel filler port 9.

  When refueling is completed, the cap 9a is attached again, and the fuel container 22 is lowered from the fuel container stand 18.

  Next, the holding portion 23 is gripped again and pushed in the direction of the arrow B, and the protrusion 21 is rotated in the direction of the arrow F in FIG. After moving, if it is further pushed in the direction of arrow B and rotated in the direction of arrow D in FIG. 4, the mounting portion 23 is fitted into the clamp 25 and locked.

  Then, after closing the opening / closing cover 12 opened in that state to the original state, the operation may be resumed.

  In the second embodiment, the mounting portion 23 of the fuel container stand 18 is gripped and pulled out in the direction of arrow A (G direction), and the tip side of the mounting portion 23 is released from the locking of the clamp 28. If the projection 29 is pulled out until it contacts the rear side wall 17c of the support member 17 and is rotated in the direction of arrow E in FIG. 7, the projection 29 contacts the receiving portion 17a to form the contact portion 27. Therefore, the fuel container 22 may be placed on the placing portion 23 set in the horizontal state to replenish the fuel.

  And when storing the fuel container mounting stand 18, the mounting part 23 is gripped on the contrary, it rotates in the direction of arrow F, and the mounting part 23 stands up in the direction of arrow B (H direction). And the tip of the mounting portion 23 is locked to the clamp 28.

  Therefore, according to the present invention, in particular, the fuel container stand 18 having the support member 17 fixed to the portion adjacent to the fuel filler port 9 of the fuel tank 15 and having the shaft-like support portion 20 and the fuel container placement portion 23. The support portion 20 is movable in the axial direction with respect to the support member 17 and is pivotally supported around the axis, so that the fuel container mounting base 18 is in the storage position and the mounting portion 20 is directed vertically. When the drawer is pulled out, the mounting portion 20 is positioned so as to face in the horizontal direction, so that the configuration of the fuel container stand 18 is simplified and there is no obstacle in the storage state of the fuel container stand 18. There is no such thing as it, and the fuel refueling posture is high enough to perform a simple pull-out operation, so that fuel replenishment can be performed smoothly.

  In addition, since the fuel container mounting base 18 of the present invention is mainly composed of a simple shaft-like member, it may be provided in another installation location adjacent to the fuel filler port 9 and the appearance in the stored state is impaired. There is no such thing.

  Further, since the mounting portion 20 of the fuel container mounting table 18 also serves as a grip for moving it, the operation is performed when the mounting table 20 is stored or set to the fuel container mounting position. Therefore, it is not necessary to wear a grip for the purpose.

  Furthermore, due to the protrusion 21 (29) provided on the support portion 20 of the fuel container stand 18 and the receiving portion 17 a provided on the support member 17, the placement portion 23 is placed at the placement position of the fuel container stand 18. Since the abutting portion 27 positioned in the horizontal state is configured, the placing portion 23 is surely secured by the abutting portion 27 when the fuel container placing base 18 is set to the placing position where the fuel container 22 is placed. The horizontal state is maintained in the positioned state, and the fuel supply operation can be performed in a stable state.
