 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an explanatory view of a belt conveyor tranfluor according to the present invention, in which a is a partially cutaway front view, b is a view taken along arrow XX of a, and c is a right side view of a. In the figure, 1 is a horizontal roller, 2 is a roller mounting base for the horizontal roller 1, 3 is an inclined roller, 4 is a roller mounting base for the inclined roller 3, and 5 is a roller mounting frame. The horizontal roller 1 and the inclined roller 3 have the same structure as the conventional one.

The roller mount 2 has a main body 6 made of equilateral angle steel, and support arms 7, 7 for supporting the horizontal roller 1 are welded and fixed to the left and right ends of the main body 6, respectively. A U-shaped groove 9 for supporting the shaft 8 of the horizontal roller 1 by dropping it is formed at the upper end of 7.

The roller mount 4 has the same basic structure as the roller mount 2 described above, and the main body 10 is made of equilateral angle steel, and the left and right ends of the main body 10 support the inclined rollers 3 with different lengths. Arms 11 and 12 are vertically fixed by welding, and a U-shaped groove 14 for dropping and supporting the shaft 13 of the tilt roller 3 is formed at the upper ends of the support arms 11 and 12.

The roller mounting frame 5 is made of equilateral angle steel having a length such that the roller mounting base 2 can be mounted in the center and the roller mounting bases 4 can be mounted on the left and right of the roller mounting frame 5.
