Traditionally, crab bucket type unloaders have been used as machines for unloading bulk materials such as ore and coal from ships, but they generate dust and noise, or cannot reach every corner of a ship's hold with a crab bucket. The disadvantage was that it was inefficient as it required the use of a bulldozer to scrape the water into the center of the hold. As a countermeasure against these problems, various so-called continuous unloaders are being researched and developed, but this type of unloading equipment has a structure that prevents the reaction force caused by the ship's movement from being transmitted to the unloading equipment, and it also prevents loose objects from being scattered in every corner of the ship's hold. It is desirable to have the function of raking. As a continuous type unloading device, (i) the lower part of the bucket elevator g is connected by connecting the bucket e with a wire rope f etc. (Fig. 1a), (ii) a hydraulic cylinder etc. is installed to connect the bucket elevator g with a wire rope f, etc. (Fig. 1b), (iii) provide a device i exclusively for raking in addition to the device h exclusively for vertical transport (Fig. 1c); As a means, a chain conveyor, a conveyor with fins, etc. are formed into an L-shape (FIG. 1d), but each of them has the following drawbacks.

The system shown in FIG. 1A can absorb the reaction force caused by the shaking of the ship, but when the load has a large excavation resistance, the bucket does not dig in, and the wire rope wears out rapidly, making it troublesome to replace the wire rope.
The system shown in Fig. 1b is designed to absorb the reaction force caused by the ship's motion using hydraulic cylinders, etc., but it requires enough force to constantly support the tension of the row of buckets, making it completely free. Can not. Therefore, the structure for removing slack in the upper bucket row, in which a certain amount of thrust force is transmitted to the unloader, becomes complicated. The device shown in FIG. There are problems with spillage, reduced efficiency, and dust generation.
In addition, two systems of drive systems are required, which makes the drive system complicated, and in particular, the drive system k for the raking device must be installed at the bottom of the vertical transport device h, so it is prone to break down due to being covered with loads, and it is not possible to inspect it during work. There are drawbacks.
Moreover, the one shown in FIG. 1d cannot absorb the reaction force caused by the ship's motion. The present invention solves all such problems by supporting a vertically extending cover rotatably around a vertical axis, and pivoting a bendable frame consisting of at least two sections to the lower end of the cover. A bent part holding device is provided at a required position of the cover to freely release each joint of the frame upwardly and hold it downwardly, and the bending angle can be adjusted, and the bent part holding device and each joint are connected to each other. A pair of pulleys connected to each other and facing each other at the lower end of the cover are provided, and pulleys are provided at the tip of the frame and the node of the frame, and scooping tools such as buckets are endlessly connected by a flexible body. The device is characterized in that a row of scooping tools stored in the cover and exposed below the cover is hung around the pulley to form a bent portion that can be bent into two or more stages.

The unloading device 9, which was initially positioned as shown by the two-dot chain line in FIG. 2, is brought into contact with the cargo upper surface of the hold by operating the unloader 1. In this state, if the bucket row 34 is driven in the direction of arrow A, the bulk goods are excavated and unloaded and transported via the belt conveyor 12, chute 11, and belt conveyors 13 and 15. Unloading device 9
When moving the hatch 4, the unloader 1 is moved, the booms 6 and 6' are rotated, the booms 6 and 6' are raised and lowered, and the unloading device 9 is rotated.
It can be moved to any position within 0. In addition, although the hatch 40 of the normal ship 5 is narrower than the hold 39 as shown in FIG. It can be excavated and unloaded. During this unloading operation, the winding devices 28, 2
By driving 9, the lengths of the cables 30 and 31 are adjusted, and the angles of the triangular frame 25 and the swinging frame 26 are changed in accordance with the shape and properties of the accumulated cargo 41. Further, these frames 25 and 26 are limited only at their lower limits by the cables 30 and 31, and can freely rotate upward, so that the frames 25 and 26 can prevent the vertical movement of the ship 5 during unloading operations. The unloading device 9 absorbs the force by the rotational movement of the ship 5, thereby preventing the unloading device 9 from receiving excessive force due to being pushed up from the ship 5. When there is little cargo 41 remaining and it is time to perform the work of digging out the bottom of the ship, the excavated portion 43 of the bucket row 34 supported by the triangular frame 25 and the swinging frame 26 is placed on the ship's bottom 42, and the anchor cables 30 and 31 are loosened. In other words, the excavating portion 43 is in close contact with the ship's bottom 42, and can effectively perform bottom-roughing work while moving up and down in response to the up-and-down movement of the ship 5. In this case, the load acting on the ship's bottom 42 is approximately the weight of the excavated portion 43 and will not damage the ship's bottom. If the cables 30 and 31 are left sufficiently slack in this way, the tip of the triangular frame 25 can freely move by the distance H in the vertical direction, so there is no need for the driver to carefully adjust the excavation height. , and depending on the nature of the cargo, the excavated portion 43
However, by adding the weight of the excavated portion 43, the biting force can be increased. Furthermore, the covers 23 and 38 described above are effective in preventing the generation of dust and in terms of soundproofing.

As described above, according to the present invention, (i) Since the excavation section and the unloading section of the bucket row are continuous, only one set of drive device is required, and there is no spillage or dust generation, resulting in a simple structure. ii) Since the rows of buckets are formed into an approximately L shape,
(iii) The bottom of the L-shaped bucket row is folded and swings in two or more stages, so the inclination of the excavation part can be adjusted according to the piled shape and properties of the cargo. When pushing up, the excavated part rests on top of the load or the bottom of the ship and can rise freely, so no undue force is generated.When the bottom is scraped, the excavated part moves along the bottom of the ship, resulting in good scooping efficiency.
(iv) The overall structure is simple and the device can be made lightweight, so the load on the tip of the unloader is small, and the uplifting force of the ship is not generated, so the unloader It can exhibit excellent effects such as reducing the overall strength and making it lighter.
