2, the conveyor support members 5a and 5b of the conveyor device 2 are provided upright with respect to the ground surface 205 and support both ends in the conveying direction of the conveyor device 3. The conveyor device 2 is in an inclined position in which the conveying surface 6 of the conveyor device 3 is inclined.
The conveyor device 3 has bottom side wall portions 17 of the frame members 11, 12 placed on the placement plate portions 70 of the conveyor support members 5a, 5b and fixed by fastening elements (not shown).

As shown in FIG. 1, the frame members 11 and 12 are disposed opposite each other with the roller 10 therebetween, with a predetermined gap therebetween in the inward/outward direction Y (a direction perpendicular to the conveying direction and also perpendicular to the height direction).
The rollers 10 are arranged side by side at predetermined intervals in the conveying direction, and are connected to each other by a belt.
When the conveyor device 3 is in a horizontal position, the height of the top of each roller 10 is the same, and the top (top) of each roller 10 forms the conveying surface 6. In other words, the conveying surface 6 is an imaginary surface connecting the tops of the rollers 10, and is an imaginary surface through which the bottom of the conveyed object 200 passes.

As can be seen from FIG. 4, the conveyor side member 30 has the fixing member 41 fixed at the upper end side by the second fastening elements 42a and 42b. That is, the second fastening element 42a passes through the reference hole 75 from the outside of the outer plate portion 55 and engages with the fixing mounting hole 62, and the second fastening element 42b passes through the angle adjustment groove 76 from the outside of the outer plate portion 55 and engages with the fixing mounting hole 63.

As shown in FIG. 5, at the lower end side of the conveyor side member 30, a part of the lower end side of the main body member 40 is arranged within the ground side recess 89 of the ground side member 31, and each conveyor side recess 59 is arranged in the same direction as the ground side recess 89 of each ground side member 31. In other words, in the conveyor side member 30, each plate portion 55-57 of the first main body portion 50 (second main body portion 51) overlaps with each plate portion 85-87 of the ground side main body portion 80 of the ground side members 31, 31.

As shown in Figures 5 and 6, the rotating member 32 has a rotating side shaft portion 101 inserted through the rotating side regulating portion 102 and further inserted through the conveyor side screw hole portion 65 of the conveyor side member 30, and the tip portion abuts against the bottom plate portion 88 of the ground side member 31. That is, the rotating side shaft portion 101 of the rotating member 32 has a rotating side screw portion 105 screwed into the rotating side regulating portion 102 at the middle portion, and further screwed into the conveyor side screw hole portion 65 below the rotating side regulating portion 102.

The conveyor-side insertion groove 60 and the ground-side insertion groove 90 extend in the same direction and overlap in the inward-outward direction Y, forming a communication hole 120 that communicates in the inward-outward direction Y.
The communication hole 120 is a communication groove extending with a vertical component, and the communication hole 120 in this embodiment extends in the vertical direction Z as shown in FIG.

The conveyor-side fixing groove 61 and the ground-side fixing holes 91, 92 overlap in the inward/outward direction Y as shown in FIG.
The shafts 116, 116 of the first fastening members 110, 111 pass through the conveyor side fixing groove 61 and the ground side fixing holes 91, 92 as shown in FIG. 7, and are engaged with shaft holes 117, 118 of the second fastening member 112 within the conveyor side recess 59.

Next, we will explain the recommended procedure for adjusting the height of the conveyor side member 30 using the tool 201.

First, while loosening the first fastening members 110, 111, engage the first fastening members 110, 111 with the second fastening member 112 as shown in FIG. 7, insert the insertion shaft portion 211 of the tool 201 into the communication hole 120, and engage the tool side engagement portion 212 provided at the tip of the insertion shaft portion 211 with the engagement hole 103.

At this time, the insertion shaft portion 211 of the tool 201 is inserted into the communication hole 120 at an angle along the extension direction of the communication hole 120.

Then, the operating part of the tool 201 is operated to rotate the tool side engagement part 212 while maintaining the inclined state of the insertion shaft part 211 of the tool 201, thereby rotating the rotating member 32 via the engagement hole 103.

At this time, as the rotating member 32 rotates, the rotating member 32 moves in the up-down direction Z due to the screw-in relationship between the rotating side screw portion 105 of the rotating member 32 and the conveyor side screw hole portion 65 of the conveyor side member 30, but since the tip of the rotating member 32 abuts against the bottom plate portion 88 of the ground side member 31 relative to the conveyor side member 30, the conveyor side member 30 rises and falls relative to the ground side member 31. That is, when the rotating member 32 is rotated in the forward direction as shown in FIG. 8, the conveyor side member 30 rises relative to the ground side member 31, and when the rotating member 32 is rotated in the reverse direction, the conveyor side member 30 descends relative to the ground side member 31.

When the conveyor side member 30 reaches the desired height, as necessary, as shown in FIG. 9, the second fastening element 42b is loosened and engaged with the fixing mounting hole 63, and the fixing plate portion 71 is moved along the angle adjustment groove 76 to adjust the inclination angle of the loading plate portion 70, thereby adjusting the angle of the conveying surface 6 of the conveyor device 3, and the second fastening element 42b is tightened again to fix it in the fixing mounting hole 63.
