Description

The present invention relates to a conveyor case of a conveyor that conveys powders and granules.

In a grain processing plant or the like, a transporter suitable for transporting powder or granular material is generally provided. As such a conveyor, there is a chain conveyor (see Patent Document 1). As shown in FIG. 6, the chain conveyor 19 has a transport scraper attached to an endless chain that rotates across a drive-side gear shaft and a driven-side gear, and transports powder or granular material or the like by the scraper. Is.

Then, in adjusting the transport distance for loading and discharging the powder or granular material, it is arbitrarily set by connecting a plurality of conveyor cases 20 and 21 composed of a top plate, a side plate and a bottom plate in the transport direction. is there.

By the way, in the chain conveyor 19, in order to normally and stably operate (rotate) the endless chain inside the conveyor case, the endless chain and the scraper do not come into contact with the inner surfaces of the conveyor cases 20 and 21. As described above, it is necessary to arrange the connected conveyor cases 20 and 21 in a straight line state. However, since the adjacent conveyor cases 20 and 21 are connected via the connecting plate 16 and the bolt 17, the conveyor cases 20 and 21 after assembly do not become linear due to bending or twisting at the connecting portion, and the above There is a concern that energy loss, foreign matter, and abnormal noise may occur due to the endless chain coming into contact with the inner surfaces of the conveyor cases 20 and 21.

For this reason, when connecting and assembling the conveyor case, it is necessary to stretch the piano wire or the like straight and use this as a reference while checking the linear state. Further, even when the piano wire is used, if a large number of conveyor cases are connected, the entire conveyor case may be bent or twisted in the middle after assembly, and it is necessary to rework the conveyor case, which is very difficult to assemble. It took time and effort.

In addition, in the assembled conveyor case, the load is concentrated on the connecting part of the conveyor case, so a reinforcing material is used for the connecting part in advance, and the thickness of the conveyor case is increased in consideration of the tension load during operation. There was also the problem of having to take measures such as doing so.
