DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveyor belt supporting device for conveying powdery and granular materials such as earth and sand, quarry and coal.

[0002]

2. Description of the Related Art Conventionally, in a conveyor belt conveying device, a powdery material such as earth and sand or cement or a massive material such as ore or coal is dropped onto a belt conveyor from a stove or a hopper and the like. A carrier guide for supporting the conveyor belt is used on the lower surface side of the conveyor belt in order to alleviate the impact caused by the falling and throwing of the conveyed object when being conveyed on the conveyor belt. The carrier guide is composed of two groups, a carrier roller horizontally arranged at the center of the conveyor belt and rollers arranged corresponding to the outer slopes on both sides. From above, cushions the impact of falling objects on the conveyor belt, prevents excessive deflection and vibration of the conveyor belt, and provides skirt plates on both sides of the belt in the conveying direction to provide Techniques for preventing falling are well known. However, depending on the load, only the carrier roller has a small supporting area and a long gap is formed between the carrier rollers before and after in the transport direction, so that not only the impact cannot be sufficiently reduced, but also the weight of the transported article can be reduced. In addition, the belt is bent, resulting in a gap between the belt and the skirt plate, and the conveyed material spills out of the gap, resulting in generation of dust. Had become. In order to support the belt conveyor in the gap between the carrier rollers from below, a carrier guide composed of a low-abrasion resin plate and a buffer has been developed, thereby increasing the contact area between the belt conveyor and the carrier guide. It was possible to sufficiently alleviate the impact of falling objects, to prevent the belt from bending or gaps, and to solve the problem of the generation of dust on the conveyed articles from the gaps in the conveyor belt (see FIG. 60). JP-137711, Shokai 62
-183609). However, if the carrier guide is arranged only at the drop point where the conveyed object falls from the guide st, the effect of reducing the impact of the conveyed object can be exhibited. The contact friction between the belt and the carrier guide becomes excessive, so that the conveyance is not performed smoothly, and there is a new problem that the wear and loss of the belt and the carrier guide are large.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a conveyor belt conveying apparatus which drops a conveyed material such as powdery and granular materials onto a belt conveyor and transfers the material on the belt conveyor. To develop means capable of preventing generation of dust due to impact due to injection and generation of dust due to bending of a belt in a conveyance area, smoothly performing conveyance, and reducing abrasion wear of a belt and a carrier guide. It is.

[0004]

In view of the above situation, the present inventor has made intensive studies and as a result, it has been possible to prevent the generation of dust in the conveyor belt conveying device, to carry out the conveyance smoothly, and to wear the belt and the carrier guide. We succeeded in developing means that can reduce losses. The present invention relates to a conveyor device using both a carrier roller and a carrier guide. The present invention basically has the following configuration. (1) The width of the carrier rollers arranged in a trough shape for supporting the conveyor belt is narrowed in the width direction as compared with the normal arrangement, the narrowed portion is used as a space area, and is made of a low-wear resin coating material. A conveyor belt support device having a carrier guide disposed in the space. (2) A conveyor belt supporting device, wherein a carrier guide comprising a low-wear resin coating material and a hollow buffer is disposed in a gap in a conveying direction of a carrier roller arranged in a trough shape. (3) A conveyor belt support device, wherein at least one carrier roller is divided and arranged on at least one flat area of the conveyor belt and on each side wall of the outer high slope on both sides. (4) A conveyor belt support device comprising a total of three carrier rollers, one in a flat area and one on each of outer high side walls on both sides. (5) A conveyor belt supporting device wherein a long hole is provided in a side portion of a hollow buffer of a carrier guide attached to a lower surface of a low-wear resin coating material, and a shaft of a carrier roller is inserted through the long hole. (6) A conveyor belt supporting device, wherein ultra-high molecular weight polyethylene is used as the low friction resin of the carrier guide.

[0005]

According to the conveyor device of the present invention, the width of the conveyer of the carrier roller arranged in a trough shape is made shorter than the normal length, and the shortened width direction end is used as a space area. Since the carrier guide made of a low-wear resin coating material is arranged, the advantage that the conveyor belt can be supported by both the carrier roller and the carrier guide is exerted, and the carrier roller can perform the conveyance without friction. Since the belt is prevented from bending and the low-wear resin coating material sandwiches the conveyor belt between the skirt plate and the skirt plate so as not to form a gap between the belt and the skirt, spills of the conveyed powder and granules occur. Prevents dust from being generated. The low-wear resin coating material has a rectangular shape and a long shape, and a low-wear resin such as ultra-high-molecular-weight polyethylene or abrasion-resistant polyamide is used. High molecular weight polyethylene is suitable from the viewpoint of abrasion resistance. The hollow support has a reinforcing effect and a buffering effect on the low-wear resin coating material, and is preferably a rectangular hollow member, and is joined to the low-wear resin coating material by bolts or the like.
