Description

[Detailed description of the invention] This invention relates to a device for moving powder and granular materials in a ship's hold.The purpose of this invention is to save power by minimizing the running resistance of the endless rotating body in a device that uses an endless rotating body. The purpose is to facilitate the maintenance and inspection of repairs and inspections.

As shown in FIG.
It has a plurality of chevron structures 3 extending in the bow and stern direction on the top. The powder and granular materials stowed in the holds 1 are first discharged into a space held between each hold 1, and then transferred out of the ship by a vertical screw conveyor or the like. For this reason, an in-hold moving device consisting of an endless rotating body 4 provided with a large number of scrapers between a plurality of chevron-shaped structures 3 is provided.

Conventionally, as is clear from FIG. 1, the endless rotating body 4 is arranged so that its forward path 4A and return path 4B are located above and below each other between a plurality of mountain-shaped structures 3, and the running resistance on the return path 4B is reduced. In order to reduce this, a chevron-shaped cover 5 was attached to the upper part of the return path 4B. However, in the conventional case, not only is an extra cover 5 required in addition to the endless rotating body 4 as the original moving device in the hold, but also the provision of the cover 5 causes the inside of the cover 5 to exist as a dead space. Furthermore, there was a drawback that repairs and inspections of the chains, etc. that constituted the endless rotating body could not be carried out when there was cargo.

The present invention has been devised in view of the above, and embodiments thereof will be described below with reference to FIGS. 2 to 6.

Reference numeral 10 indicates a hold, 11 a plurality of chevron structures provided on the hold bottom plate 12, and 13 a space formed between the hold 10. A passage 14 is formed at one end corner of the inner bottom of the hold 10, and an endless rotating body 15 is disposed between the passage 14 and the space 13. That is, the endless rotating body 15 has its forward path 15A arranged along the valley 16 between the respective chevron-shaped structures 11, and its return path 15B along the upper part of the chevron-shaped structure 11. In addition, each return path 15B of the endless rotating body 15 disposed on the left and right sides of the central mountain-shaped structure 11A is provided. Endless rotating body outward path 15A
The wheel body 17 around which the starting end and the ending end of the endless rotating body return path 15B and the starting end and the ending end of the endless rotating body return path 15B are respectively wound.
A, 17B, 18A, and 18B are installed inside the predetermined space 13 and passage 14, respectively.

The endless rotating body 15 is formed by endlessly connecting unit links 19 as shown in FIGS. 6a to 6c. That is, the unit link 19 is formed by connecting the opposite ends of link plates 20 with pins 21, and fixing a scraper plate 22 projecting laterally to the center of the link plates 20. Also, the outward path 15 of the endless rotating body 15
Since the communication path 15c connecting A and the return path 15B is arranged diagonally, the rotation axes of the wheels 17A, 17B, 18A, and 18B are aligned with the horizontal line, as shown in FIGS. 5a and 5b. It is supported while being inclined at the same angle (45 degrees in the illustrated example). Therefore, the scraping plate 22 is moved to the endless rotating body outward path 1.
5A, the scraper plate 22 is protruded and inclined at the same angle as the above angle (45 degrees in the illustrated example) with respect to the vertical line to the link plate 20. On the other hand, a powder collection section 23 is formed at the end of the outward path of the endless rotating body 15 in the space 13, and this collection section 23 and the deck 24
Vertical lifting screw conveyor 2
5 is provided.

According to the above, the endless rotating body forward path 15A runs in the valley 16 between each mountain-shaped structure 11 as before,
At this time, the scraper plate 22 moves the powder into the collection section 23 within the space 13 . Also, the endless rotating body return path 15B
Since it travels inside the chevron-shaped structure 11, there is no contact with the granular material, and therefore, no increase in running resistance due to the travel of the endless rotating body return path 15B can occur. Repair and inspection of the endless rotating body 15 is performed inside the chevron-shaped structure 11, and the presence or absence of cargo in the hold 10 is not directly relevant at that time.

As is clear from the above explanation, according to the present invention, the return path of the endless rotating body is run inside the chevron structure, which is the hull structure at the bottom of the hold, so that the cargo (powder) and the return path of the endless rotating body are connected. Running resistance is completely eliminated, leading to power savings. Moreover, this configuration reduces the frequency of damage to the endless rotating body, and allows repairs and inspections to be carried out regardless of the presence or absence of cargo in the hold. Furthermore, there is no need to provide an extra cover like in the past, and therefore no dead space is created, so equipment costs can be reduced.
This can prevent a decrease in the loading rate.
