【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows an embodiment of the present invention.

Since the entire configuration is the same as that of FIGS. 2 to 4, reference will be made to FIGS. 2 to 4 as necessary.

In the figure, 2 is a ship, 3 is an outer plate of the ship 2, 4 is a hold inside the ship 2, 5 is a rib for reinforcing the outer plate 3 provided on the hold 4 side, 12 is a bucket elevator, Reference numeral 15 is a scraping sprocket for the bucket elevator 12, 16 is a chain suspended on the scraping sprocket 15, 17 is a bucket attached to the chain 16 at a predetermined interval, and 18 is a load on the bucket elevator 12. The scraping unit 28 is a load.

Then, a bifurcated bracket 31 is attached to the rotary shaft 30 of the scraping sprocket 15, and the arm portion 32 below the bracket 31 is loaded with a bucket 17 which is turned over along the scraping sprocket 15. A movable protector 33, which protects from collapse, is pivotally attached to a vertical pin using a horizontal pin 34 so as to be tiltable in the vertical direction.

Then, between the movable protector 33 and the upper arm portion 35 of the bracket 31, the movable protector 33 is tilted in the vertical direction so that the load 28 from the lower portion A of the movable protector 33 to the load scraping portion 18 is loaded. A tilting device 36 such as a cylinder capable of adjusting the flow rate is provided.

Further, a support base 38 is attached to the upper part B of the movable protector 33, a swivel device 39 such as a hydraulic motor or an electric motor is attached to the upper part of the support base 38, and a swivel base is attached to the rotary shaft of the horizontal swivel device 39. 40 is rotatably attached to the left and right, and a high-pressure water jet nozzle 42 is pivotally supported on the upper part of the swivel base 40 via support legs 41 so as to be vertically tiltable, and a cylinder is provided between the swivel base 40 and the high-pressure water jet nozzle 42. The high-pressure water jetting device 44 is configured by interposing the nozzle tilting device 43 such as the above.

Next, the operation will be described.

The process of scraping the load 28 in the hold 4 by the bucket elevator 12 and carrying it to the cable tray 25 using the boom conveyor 23 and the in-machine conveyor 24 is the same as in the case of FIG.

In the present invention, since the high-pressure water jetting device 44 is attached to the upper portion B of the movable protector 33, the load remaining on the periphery of the rib 5 that cannot be scraped off by the bucket 17 or the groove 27 of the partition wall 26 is increased. The scraping work 28 can be performed by injecting high-pressure water from the high-pressure water injection device 44.

At this time, the swivel device 39 swivels the swivel base 40 left and right, and the nozzle tilting device 43 tilts the high-pressure water jet nozzle 42 in the vertical direction, so that the swivel base 40 is swung toward an arbitrary position. High-pressure water can be jetted to scrape the load 28.

Further, according to the present invention, when a load collapse occurs in the hold 4, the tilting device 36 such as a cylinder is contracted and the movable protector 33 is tilted upward as shown by a virtual line a. To do so.

As a result, the collapsed load 28 is prevented from falling along the load scraping portion 18 onto the bucket 17 in the inverted portion and filling the bucket 17 to cause an overload.

When the load is not collapsed, the tilting device 36 such as a cylinder is extended to tilt the movable protector 33 downward to move it to the position indicated by the solid line or the position indicated by the phantom line B. It is positioned so that the flow rate of the load 28 from the lower portion A of the movable protector 33 to the load scraping unit 18 is adjusted.

As a result, when the load 28 has good fluidity, the movable protector 33 is held at the position of the virtual line B and the load is scraped from the lower portion A of the movable protector 33 as shown by the virtual line C. By controlling the flow amount of the load 28 to the portion 18, it is possible to optimize the scraping amount and the scraping resistance of the load 28 by the bucket 17.

On the contrary, when the fluidity of the load 28 is poor, the movable protector 33 is held at the position indicated by the solid line, and the lower portion A of the movable protector 33 moves to the load scraping portion 18 as shown by the solid line D. It is possible to relax the regulation of the flow amount of the load 28 and optimize the scraping amount and the scraping resistance of the load 28 by the bucket 17.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and it goes without saying that various modifications can be made without departing from the gist of the present invention.

[0039]

[Effect of device]

 As described above, according to the continuous unloader of the present invention, it is possible to achieve an excellent effect that the work of scraping off the load on the portion that cannot be scraped by the bucket can be automated.
