  FIG. 5 is an exploded perspective view for explaining a support structure of the refueling tank mounting table 30.

  FIG. 6 is a cross-sectional plan view of the support structure of the refueling tank mounting table 30.

  As shown in FIG. 5, a pair of left and right first notches 61a, 61a and a pair of upper and lower second notches 61b, 61b are provided at an edge 61 of the support member 60 facing the rear side of the traveling vehicle body 1a. A total of four notches are provided, and a rib-shaped convex portion 32 that can be selectively fitted to any one of the notches 61a to 61b has a refueling tank mounting table in an operating posture. It is formed in a direction perpendicular to the axis of the rotating shaft portion 31 from both sides of the root portion of the rotating shaft portion 31 fixed to the rear end side of the rotating shaft portion 30 and parallel to the mounting surface 30a of the refueling tank mounting table 30. I have.

  A first virtual line (not shown) connecting the centers of the notch widths of the pair of left and right first notches 61a, 61a is horizontal to the ground, and the notches of the pair of upper and lower second notches 61b, 61b. It is configured so as to be orthogonal to a second imaginary line (not shown) connecting the centers of the widths and that the intersection point is located on the axis P of the support member 60.

  Note that the axis of the rotating shaft 31 and the axis P of the support member 60 (see FIGS. 5 and 6) match in the assembled state.

  As shown in FIGS. 5 and 6, the support structure of the refueling tank mounting table 30 includes a rotating shaft 31 fixed to an edge of the refueling tank mounting table 30, and the rotating shaft 31 inserted therein. The compression spring 64 is moved to the distal end of the rotation shaft 31 via a cylindrical support member 60 that rotatably supports the rotation shaft 31 and a flat washer 65 and a spring washer 66 inside the support member 60. And a lid member 68 detachably attached so as to cover the front edge portion 69 of the support member 60 to prevent the bolt 67 from coming off.

  Specifically, as shown in FIG. 6, the inside of the cylindrical support member 60 has a first hole 62 having a circular cross section in which the rotation shaft 31 is rotatably supported, and one of the first holes 62 has the first hole 62. The second hole 63 communicates with the hole 62, and the other communicates with the opening of the front end edge 69, and has a larger inner diameter than the first hole 62. The cylindrical compression spring 64 has a maximum outer diameter larger than the inner diameter of the first hole 62 and smaller than the inner diameter of the second hole 63.

  Further, the compression spring 64 inserted into the second hole 63 in a compressed state, the tip of the bolt 67 inserted from the spring washer 66 side through the flat washer 65 and the spring washer 66, and the rotation shaft 31 A structure in which a biasing force (elastic force) always acts on the rotating shaft 31 in the direction of arrow R by being screwed into a bolt mounting hole 33 formed so as to match the axis of the shaft. It is.

  Here, the length of the compression spring 64 inserted into the second hole 63 and held by the bolt 67 is such that the rib-shaped protrusion 32 is fitted to any one of the four notches 61a to 61b. In this case, the bolt 67 is tightened to a length slightly reduced from the natural length, and the rib-shaped protrusion 32 is not fitted with any of the four notches 61a to 61b. In this case, the bolt 67 is pulled in the direction of arrow Q (see FIG. 6) together with the rotating shaft 31, so that the length of the compression spring 64 is further reduced from its natural length by at least the height of the projection 32. .

  Accordingly, when the rib-shaped protrusion 32 is not fitted to any of the four notches 61a to 61b, the rib-shaped protrusion 32 is attached to the compression spring 64. A larger elastic force (stretching force) is generated as compared with the case where any one of the four notches 61a to 61b is fitted, and the rotating shaft 31 is strongly pulled in the direction of arrow R (see FIG. 6). Can be

  Therefore, when the rib-shaped convex portion 32 is fitted with any one of the above-described four notches 61a to 61b, a gentle elastic force in the direction of the arrow R is always applied. When the state where the rotation shaft 31 is locked is maintained and the rotation shaft 31 is rotated to change the attitude of the refueling tank mounting table 30, the rotation shaft is opposed to a stronger elastic force generated by the compression spring 64. By pressing the portion 31, that is, the refueling tank mounting table 30 in the direction of the arrow Q (that is, the rear of the traveling vehicle body 1a in the front-rear direction) (see FIGS. 4 and 6), the rib-shaped convex portion 32 and the above four Any of the notches 61a to 61b (see FIG. 5) is disengaged and unlocked, and a load is applied upward or downward to the refueling tank mounting table 30 to rotate the rotating shaft 31. (See arrows U and D in FIG. 4).

  According to the above configuration, the refueling tank mounting table 30 is configured such that the mounting surface 30a of the refueling tank mounting table 30 is formed by fitting the rib-shaped protrusions 32 with the pair of left and right first notches 61a, 61a. It is locked in a horizontal and upward use posture (see FIGS. 2 and 4).

  As a result, the fuel tank 16 (see FIG. 2) is placed on the fuel tank mounting table 30, and the fuel tank 12 can be refueled.

  The refueling tank mounting table 30 rotated in the direction of arrow D (see FIG. 4) has a mounting surface 30a facing the left, that is, a center portion in the left-right width direction of the traveling vehicle body 1a, and has a rib-like shape. The lubrication tank mounting table 30 is locked in the second storage position (see FIG. 7) by fitting the protrusion 32 into the pair of upper and lower second notches 61b, 61b. FIG. 7 is an enlarged perspective view of a peripheral portion of the refueling tank mounting table 30, and is a diagram illustrating a state where the refueling tank mounting table 30 is in the second storage posture.

  Further, the refueling tank mounting table 30 rotated in the direction of the arrow U (see FIG. 4) has a mounting surface 30a directed rightward, that is, rightward in the width direction of the traveling vehicle body 1a. The lubrication tank mounting table 30 is locked in the first storage position (see FIG. 1) by fitting the protrusion 32 into the pair of upper and lower second notches 61b, 61b. FIG. 1 is a diagram showing a state in which the refueling tank mounting table 30 is in the first storage position in addition to the right side view of the agricultural tractor 1 as described above.

  Accordingly, a sufficient work space can be secured when performing maintenance work inside the hood or maintenance work such as tire replacement of the front wheels 2.

  That is, by rotating the refueling tank mounting table 30 around the longitudinal axis of the traveling vehicle body 1a, a distance is set between the refueling tank mounting table 30 and the bonnet 6 in the storage posture, and the bonnet 6 in the use posture. The refueling tank mounting table 30 can be configured in the vicinity, which facilitates refueling.
