Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dispensing machine used to carry out bulk materials such as coal and ore loaded in a storage area.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 5, for example, a bulk 1a such as coal or ore carried in by a ship, a freight car, a conveyor or the like is stored in a storage 2a by a stacker (not shown). This is continuously carried out by a payout machine (reclaimer) 3a.

In this dispensing machine 3a, a scraping portion 6a formed of a bucket wheel is provided at the tip of a boom 5a that is pivotally projected on a base 4a that can travel in the front-rear direction, and the boom 5a travels and swivels. , The loose pieces 1a which are undulated and stacked by the scraping section 6a are sequentially scraped out from the upper stage by, for example, a bench cut method, and are conveyed to the hopper 8a arranged on the base 4a by the boom conveyor 7a arranged in the boom 5a, and It is carried out by a belt conveyor 9a arranged below it.

[0004]

However, in the conventional dispensing machine 3a, when the storage area 2a for loading the loose material 1a is deep digging storage having a depth of several meters, for example, when scraping near the bottom surface. The boom 5a inclines steeply (state shown by a chain line in the drawing).

Therefore, there has been a problem that the loose material 1a on the boom conveyor 7a scraped by the scraping portion 6a slips and cannot be conveyed.

Therefore, it is conceivable to use a belt conveyor for steep inclination as the boom conveyor 7a, but in general, the belt conveyor for steep inclination has a complicated structure and is expensive, and it is not possible to use it for a long boom conveyor 7a. There is a need to deal with the increase in weight and a great financial burden.

[0007]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and an auxiliary boom having a belt conveyor for steep inclination is internally scraped by descending toward an end. It was installed between the section and the boom as a means for solving the problem.

Further, in the above means, when the auxiliary boom is attached to the boom so that it can be hoisted or swung, the hoisting and turning of the boom itself can be reduced, which saves labor and improves work efficiency. Can be realized.

[0009]

Next, an embodiment of the present invention will be described.

FIG. 1 shows one of the preferred embodiments of the present invention, in which the entire structure of the dispensing machine 1 is substantially the same as that of the above-mentioned conventional example, and two storages formed opposite to each other. A rail 5 in which a conveyor belt conveyor 4 is arranged in the center is extended between 2 and 3 in the front-rear direction shown in the drawing, and a base 6 is arranged on the rail 5 so that the base 6 can travel.

A long boom 8 is mounted on the base 6 via a turning device 7 so as to be vertically rotatable at a base end 81 thereof. The boom 8 has a boom conveyor 9 accommodated therein from the tip end 82 to the base end 81, and can be undulated about the base end 81 by loosening the hoisting wire 10 connected to the tip end 82.

Further, the boom 8 is attached in a state in which the auxiliary boom 12 which is shorter than the boom 8 having a scraping portion 11 formed of a bucket wheel at the tip is inclined so as to descend toward the tip. Has been.

Inside the auxiliary boom 12, there are arranged a scraping portion 11 arranged at the tip and a belt conveyor 13 for steep inclination extending over a boom conveyor 9 inside the boom 8 arranged at the rear end.

The steeply inclined belt conveyor 13 is composed of a pair of belt conveyors 131 and 132 which are vertically overlapped with each other. In particular, in the present embodiment, the boom conveyor 9 disposed inside the boom 8 is extended. Then, a part thereof is used as the lower belt conveyor 132.

Reference numeral 14 in the drawing denotes a hopper arranged below the base end of the boom conveyor 9 on the base 6 and above the conveyor belt conveyor 4.

The dispensing machine 1 shown in the present embodiment having the above-mentioned configuration is carried in by a ship, a freight car, a conveyor, etc. and stacked in the storages 2, 3 by a stacker (not shown) as in the conventional example. The loose material 15 such as coal and ore stored together is run on the boom 8, swung, and undulated to scrape out the scraping portion 1
1, for example, it is sequentially scraped out from the upper stage by a bench cut method, sandwiched between two belt conveyors 131 and 132 constituting the steep belt conveyor 13, carried by the boom conveyor 9 and sent to the hopper 14, and further below it. It is carried out by the belt conveyor 4 provided.

At this time, in the present embodiment, an auxiliary boom 12 having a belt conveyor 13 for steep inclination inside is attached to the tip of the boom 8 in an inclined state so as to descend toward the tip.

Therefore, the storage rooms 2 and 3 where the bulk materials 15 are loaded.
In the case of deep digging storage in which the depth of is deeper than the conventional one shown by the chain line in FIG. 1, the inclination becomes steep even when scraping near the bottom surface. Only the part of the long boom conveyor 9 is used, and the bulk conveyor 15 is carried out by using an ordinary belt conveyor for inclining which is simple and inexpensive in construction as compared with the one for steeply inclining. It is economically advantageous because it is possible to increase the weight relatively little.

FIG. 2 shows a different embodiment of the present invention. The overall structure and its operation and effect are almost the same as those of the embodiment shown in FIG. Rotatably attached to the boom 8. That is, the wire 18 attached to the base end of the auxiliary boom 12 is loosened by the hoisting machine 17 provided at the base end of the boom 8 with respect to the boom 8. It is mounted so that it can be undulated.

Therefore, when scraping the bulk material 15 such as coal or ore loaded and stored in the storage areas 2 and 3, the boom 8 is not undulated within a certain range of height and a small force is applied. In addition, the auxiliary boom 12 that can be quickly operated can be scraped just by raising and lowering, and labor saving and speeding up of work can be achieved as compared with the case of raising and lowering the conventional large and heavy boom 8. it can.

Further, even in the case of deep digging storage, the auxiliary boom 12 is raised except when the vicinity of the bottom surface is scraped, that is, the auxiliary boom 12 and the boom 8 are in a linear state by the chain line shown in FIG. By keeping the state shown,
The portion of the steeply inclined belt conveyor 13 is also the boom conveyor 9
The inclination is almost the same as above, and since there is no steep inclination portion, it is possible to save labor without requiring a large driving force.

In the present embodiment, the auxiliary boom 12 attached to the tip of the boom 8 so as to be vertically rotatable,
The hoisting machine 17 provided at the base end of the boom 8 relaxes the wire 18 connected to the base end of the auxiliary boom 12 so that the boom 8 can be raised and lowered. For example, a hydraulic cylinder is used as the boom 8
It goes without saying that other means such as interposing between the auxiliary boom 12 and the auxiliary boom 12 so that the auxiliary boom 12 can be raised and lowered with respect to the boom 8 may be used.

Further, FIG. 3 shows a further different embodiment of the present invention, and the overall structure and its operation and effect are almost the same as those of the embodiment shown in FIG. The boom 12 is mounted on the turning device 19 arranged at the tip of the boom 8, and the steep belt conveyor 1 is arranged inside the auxiliary boom 12.
3 are independent of the boom conveyor 9 arranged in the boom 8, and the base end of the boom conveyor 9 extends to the table feeder 20 arranged above the swivel device 19, and the boom 3 is located below the payout portion of the table feeder 20. The tip of the conveyor 9 is located.

According to the present embodiment, especially the auxiliary boom 1
When scraping the bulk material 15 such as coal and ore stored by stacking 2 in the storage areas 2 and 3 with respect to the boom 8, the boom 8 is not rotated within a certain range in the horizontal direction. Scraping is possible by simply turning the auxiliary boom 12 that can be operated quickly with a small amount of force, and saves labor and speeds up the work compared to the case of turning the conventional large and heavy boom 8. be able to.

In particular, by combining the embodiment shown in FIG. 2 with the present embodiment, it is possible to further save labor and speed up the work.

Further, FIG. 4 shows the embodiment shown in FIG. 1 additionally provided with a tripper 21, and can be used as it is as a stacker.

In the above embodiment, the steeply inclined belt conveyor 13 has a construction in which a loose object is sandwiched between a pair of belt conveyors 131 and 132 which are vertically overlapped with each other. For example, it is possible to use another belt conveyor such as a belt conveyor with a crosspiece that has been conventionally used as a belt conveyor for steep inclination.

[0028]

As described above, according to the present invention, the auxiliary boom having the belt conveyor for steep inclination inside is attached between the raking part and the boom so as to descend toward the tip. When scraping near the bottom in the case of embedded storage, only the auxiliary boom part where the belt conveyor for steep tilting is arranged can be steeply inclined. As compared with the case of using, the bulk can be carried out with a simpler structure and at a lower cost, and the increase in weight is relatively small.

Further, in the case where the auxiliary boom is constructed so as to be capable of undulating with respect to the boom, when scraping bulk materials such as coal and ore stored in the storage area, it is possible to raise the height of the auxiliary boom. In a certain range in the horizontal direction and horizontal direction, the boom can be scraped by simply hoisting or swiveling the auxiliary boom that can be operated quickly and with less force without hoisting or swiveling the boom. The number of times of ups and downs or turns of a boom having a certain amount can be reduced, which can save labor and speed up the work.
