Description

  The present invention relates to a bucket conveyor that can efficiently convey powdery and granular materials and has a small installation space.

  What is a bucket conveyor? A plurality of buckets are mounted at equal intervals on a conveyor chain that runs in the conveyor case, and powder and granular materials that are thrown from the lower inlet of the conveyor case are put into the bucket. The powdery matter and granular matter in a bucket can be carried out from the discharge port provided in the upper part of the conveyor case. In other words, it is a conveyor that is frequently used to convey powdery and granular materials to high places.

  There are various types of powdered and granular materials to be conveyed. For example, granular materials include limestone, coal, coke, and powdery materials such as cement and incinerated ash. Generally used. By the way, the form of a bucket conveyor is various, and what is generally called an S type | mold bucket conveyor and a Z type | mold bucket conveyor is known as it shows the schematic in FIG. In these bucket conveyors, what is input from the position of the arrow is discharged from the position of the arrow.

A “bucket conveyor” according to Japanese Patent Application Laid-Open No. 11-139525 is a specific example of the Z-type bucket conveyor described above. A bucket conveyor having a chain, a drive source of the chain, and a plurality of buckets fixed to the chain and capable of circulating in the casing integrally with the chain. And a bottom plate that opens and closes the bottom opening of the bucket body. The bucket body is provided with urging means for closing the bottom plate, and the bottom plate is opened near the discharge port of the casing. Is provided with a pressing means. "
The “bucket conveyor” according to Japanese Patent Laid-Open No. 7-291420 is also a conventional example of a Z-type bucket conveyor, and has a shape in which a horizontal conveyor case extends at the upper and lower ends of a vertical conveyor case. The chain is equipped to run. One S-type bucket conveyor has an inclined conveyor case instead of a vertical conveyor case.

  By the way, since the conventional Z-type and S-type bucket conveyors have horizontal conveyor cases at the upper and lower ends of the vertical conveyor case and the inclined conveyor case, a large space is required for installation. In addition, the conveyor chain runs along the conveyor case, and is stored in a bucket such as a powdery material introduced at the inlet and discharged at the outlet, but is stored in comparison with the capacity of the bucket. The amount of objects and granular materials is small, and the conveyance efficiency is low.

FIG. 8 shows the form of a bucket used in a conventional Z-type bucket conveyor and S-type bucket conveyor. The hatched portion in the figure is a granular material to be conveyed, and the amount thereof is smaller than the bucket capacity. In other words, there are many granular materials thrown in from the upper opening, but if the direction changes with the running of the conveyor chain, it will fall to the outside, and finally the powder and granular materials contained in the shaded area Only is transported.
