ものを使用している。 A stacker moves a conveyor belt in the opposite direction and releases loose material from the tip of a boom. (Japanese Utility Model Publication No. 56-33222) The carrier roller in the bent portion B has a smaller carrier pitch than the general portion, and the trough angle θ of the carrier roller 2 is made smaller as shown in FIG.

If the belt becomes larger than this, the central part of the conveyor belt 1 at the bending part B will buckle, and the central part will bulge as shown in FIG. 2, which has the disadvantage of impairing its function as a conveyor.

In this belt conveyor, a second carrier roller for supporting the conveyor belt is disposed near the carrier roller at a bent portion of the belt conveyor, and the second carrier roller is arranged at a predetermined interval in the horizontal direction. It is characterized in that it consists of two rollers arranged in a V-shape, with a space provided between the ends of the two rollers.

An embodiment of the present invention will be described below with reference to FIGS. 3 to 7. In Figure 7, 1
The rollers 3 are arranged in a V-shape on the set of brackets 6,
A roller 4 is provided horizontally behind the roller 4 so as to supplement the gap in the center of the roller 3, and rollers 5 are arranged on both sides of the roller 4 so that the trough angle is slightly larger than the trough angle of the roller 3.

ンスする。 If such a combination of carrier rollers is used in the conveyor bending section (B section) of the reclaimer shown in FIG. It is possible to prevent the central part of the belt from bulging.
That is, the reason why the conveyor belt 1 undergoes the deformation shown in FIG. 2 at the conveyor bent portion is because compressive force acts from the belt ends toward the center. Looking at the change in the belt tension C, as shown in FIG. 3, the tension is large at the ends due to the trough angle θ and bending, and is small at the center, resulting in a compressive force toward the center. The deformation of the conveyor belt 1 due to this compressive force is shown in Figure 4.
By arranging the book rollers 3 in a V-shape and providing a gap in the center, a force P that deforms the center portion downward acts on the conveyor belt 1, and the conveyor belt 1 is balanced in the state shown in FIG.

る。 Depending on the size of the gap in the center of the V-shaped roller 3 and the magnitude of the compressive force acting on the belt, the belt may hang downward from the gap in the center. Three rollers 4 and 5 are arranged side by side as shown in Fig. 6 to ensure downward sagging and stability of the belt ends.

点がある。 In particular, if the trough angle θ 2 of the roller 5 is made larger than the trough angle θ 1 of the V-shaped roller 3, the pinching phenomenon of the conveyor belt 1 by the V-shaped roller 3 will be weakened, which has the advantage of reducing the negative effects of the pinching. be.
