As shown in FIG. 2B, the mold board forming the work surface plate 22b on the nozzle side of the double-sided blade 21 has mounting ribs 22b2 integrally on both sides of the lower surface. Since it fits inside the face plates 22c and 22d and is fixed with bolts 22g, if the bolts 22g are removed, the work face plate 22b on the nozzle side can be opened to perform maintenance of the built-in water jet nozzle 27.

FIG. 2C shows the edge fitting portion 23 viewed from the front.
The state in which are juxtaposed is specified. This drawing shows an example in which a thick plate edge 24 made of a synthetic resin is fitted to the edge fitting portion 23.

FIG. 2D shows a thin plate edge 24 made of a steel plate provided as an attachment instead of the thick plate edge 24.
'Is an example of fitting. When this thin plate edge 24 ′ is used, a spacer 29 having a thickness different from that of the thick plate edge 24 is inserted.

The thick plate edge 24 or the thin plate edge 24 'is selectively used depending on the purpose of use. For example, to avoid damage to the aggregate of the ship wall, the synthetic resin edge 24 is used. If the emphasis is on preventing wear or breakage, a steel plate edge 24 'is used. The reason why the steel plate edge 24 'is thin is to reduce the weight.

Next, the operation of this embodiment will be described.

The edge fitting portion 23 of the double-sided blade 21 has an edge.
24, insert the edge fitting portion 23 and the notch portion 28 of the edge 24.
A stopper 28b is fitted into a, and a bolt 28c is screwed into the screw hole of the stopper 28b from outside the distal end side plate portions 23a, 23b and tightened. In this manner, the stopper 28b is
This stopper is fixed to the inner surface of 23a, 23b.
28b locks the left and right cutouts of the edge 24 to prevent the edge 24 from falling off.

If the edge 24 is worn, use two bolts
Remove the stopper 28c and insert the stopper 28b into the notch 28 of the edge fitting part 23.
a, the edge 24 is pulled out from the edge fitting portion 23, and then the worn end of the edge 24 and the non-wear end on the opposite side are reversed, and the worn end of the edge 24 is returned to the edge fitting portion 23. It can be easily replaced by inserting and then inserting the stopper 28b into the notch 28a and fixing it with the bolt 28c as described above.

FIG. 4A shows that the water jet nozzle 27 is connected to the partition plate 22.
FIG. 4B shows the case where the hinge pins 20a and 20b are detached and the two-sided blade 21 is turned upside down so that the water injection nozzle 27 is positioned below the partition plate 22e. This is the case when they are replaced. For example, when the frequency of the scraping or scraping operation is different, the double-sided blade 21 is set so that the water injection nozzle 27 is located on the blade surface side where the operation frequency is low.
Can be inverted and attached, which is effective for effective use of the cutting edge 24 and protection of the water injection nozzle 27. In addition, when the water injection nozzle 27 is actively used, the water injection nozzle is
The water injection nozzle 27 may be positioned on the lower side when the work target portion is at a relatively low level.

Next, the operation of dropping a shelf will be described. For example, when coal is unloaded on the ship of a coal carrier and the first stage shelf comes out, as shown in FIG. Coal or the like deposited between H-section steels is picked up or scraped off by the double-sided blade 21 to perform a shelving operation.

In this case, the double-sided blade 21 is inserted into the coal deposited on a shelf or the like, and the blade 21 is operated by the bucket cylinder 18 using the operation lever of the bucket cylinder 18 (and, if necessary, the operation lever of the arm cylinder 16). By moving the double-sided blade 21 as shown by the dotted small circle in FIG. 3 or by the arm cylinder 16 as shown by the dotted large circle in FIG. Gradually break down as if scraping.

In this blade operation, approximately 80 to 90% of the coal deposited on the shelves and the like is scraped off, but 10 to 20% of the coal remains without being scraped off. The water is completely scraped off by the injected high-pressure water.

As described above, the water injection nozzle 27 is provided on the wall shelf,
Coal deposited between H-beams or on stairs can be washed off cleanly, and in the case of hard coal, water injection can be used as an aid to the edge. Water discharge / stop is operated in the cab.

Next, when refilling the water tank 31 with water,
As shown in FIG. 5, when the water tank unit 30 is integral with the body, at least three or more hanging hooks 35 provided on the body are lifted by an unloader or the like used for cargo handling onboard, and the water tank unit 30 is If it can be attached to or detached from the aircraft, lift at least three or more suspension hooks 36 provided on the water tank 31 and carry out the aircraft or the water tank unit 30 to the water supply base outside the boat, and place it in the water tank 31. Supply water. Further, water may be directly supplied from the water tank prepared in the ship into the water tank without removing the water tank unit 30 mounted on the body. Further, a water supply hose may be extended from a water supply base or the like to supply water into the water tank.

Although the embodiments have been described with reference to an example of a shelving machine operated inside a coal carrier, the present invention is not limited to such a dedicated machine. Also, the water injection nozzle 27 is shown as the fluid injection nozzle,
The fluid is not limited to water, and air may be jetted depending on the material to be handled. In that case, water tank
The 31 and the water pump 32 are not required, and need to be equipped with an air pump.

[0049]

According to the first aspect of the present invention, since the working face plate is formed on one side and the other side of the blade having the built-in injection nozzle, it is possible to provide a combined use of a scraping and scraping blade apparatus, and The removal of materials handled on the shelves on the wall etc. can be carried out efficiently by scraping, scraping or fluid pressure according to the deposition conditions. The nozzle can be reliably protected from handling materials.

According to the second aspect of the present invention, since the blade has a box-shaped structure in which a concave-curved work surface plate is formed on both sides of the box-shaped main body, it is possible to minimize the resistance received from the material to be handled. In combination with the cutting edge protruding from the edge fitting portion at the tip of the box-shaped main body, the scraping or scraping operation can be performed smoothly.

According to the third aspect of the present invention, since the blade is of a reversible type in which the up and down of the blade can be changed, the spray nozzle can be positioned on the blade surface side according to the work, thereby improving the work efficiency and improving the spray nozzle. Effective use can be achieved.

According to the fourth aspect of the present invention, the stopper is inserted into the notch portion of the cutting edge from the notch portion on the working surface side of the edge fitting portion, and the bolt inserted from the left and right side surfaces of the edge fitting portion. By fixing the stopper, the falling off of the cutting edge can be reliably locked, and the positioning of the bolt when screwed in can be performed more easily than when the bolt is directly screwed into the stopper. Then, when the cutting edge is worn, it is possible to easily reverse the edge wear end and the opposite end.

According to the fifth aspect of the present invention, a thin plate edge or a thick plate edge can be fitted to the edge fitting portion of the blade according to the purpose depending on the presence or absence of the spacer.
