DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 shows a stack of bulk materials (coal,
Ore) is shown from a diagonally above view.

The bulk storage yard 1 is provided with a sheet hanging device for covering the pile 7 of bulk materials stacked thereon and preventing dust from being generated from the pile 7.

This sheet hanging device is provided with a large number of first winches 1 arranged on the road shoulders 10 on both sides of the pile 7 at intervals in the longitudinal direction thereof to stretch the first rope 11 on the top of the pile 7.
2 and a stacker 2 that moves to the side of the pile 7 and is attached to a base 14 at the end of a boom conveyor 13.
The first winch 15 of the adjacent first winch 12 of the multiple first winches 12 on both sides of the pile 7 is connected to the tip of the first winch 15 and pulled to the top of the pile 7 for tension. A sheet suspended in the form of a curtain via suspending fittings 16 such as a shackle so that at least an upper half of the slope of the pile 7 and at least a half of the top of the pile 7 can be covered when the sheet is expanded. And the third winch 18 provided on both sides of the pile 7 to adjust the retaining position of the rear end of the mesh sheet 17, and the sheets on both sides of the pile 7 are drawn into the top of the pile 7 respectively. And a fourth winch 19 attached to the base 14 to expand.

FIG. 2 specifically shows the structure of the mesh sheet 17, and FIG. 3 shows a hanger stand provided on the road shoulder 10 for collecting the mesh sheet 17 in a folded state.

As shown in FIG. 1, a mesh sheet 17 is provided.
Is the right slope (or left slope) of the pile 7 when it is expanded
10 m and a length of 4 m so as to cover at least the upper half of the
It is cut into a rectangle having a length of 0 m, and as shown in FIGS. 1 and 2, the aggregates 20 are attached at intervals in the longitudinal direction so as to be folded in a curtain shape. Then, as shown in FIG. 2, by inserting holes 21 at both ends provided in a portion directly below the aggregate 20 into pole-shaped members, the pole can be hung in a folded state. The U-shaped hanging bracket 16 is integrally attached to both ends of the aggregate 20 (in order to reinforce the hole 21 of the mesh sheet 17, metal around the edge of the hole 21 by caulking or the like). It is also possible to attach a rim ring.)

As shown in FIG. 3, the hanger stand 22
On the upper part of the leg 23 fixed to the road shoulder 10, the third winch 1
8 has a pole 24 which is drawn toward the road shoulder 10 and is inserted into the hole 21 of the mesh sheet 17 to be folded, and has a pulley 26 for guiding the first cable 11 of the first winch 12 smoothly. ing. The third winch 18 is adapted to be operated by air of a pneumatic line provided along the bulk storage yard 1.
The winch 12, the second winch 15, and the fourth winch 19 are hydraulically or electrically driven.

Here, the reason why the mesh sheet 17 is used as the sheet is that, when the sheet is spread and when the sheet is spread, the sowing by the wind is much smaller than that in the case where the entire surface is coated, and the entire surface is coated. This is because a dust generation suppressing effect comparable to that obtained by coating can be obtained. Further, the top surface of the pile 7 and the upper half of both slopes are covered by the mesh sheet 17 forming a pair in the transverse direction of the pile 7 because dust generated by the wind is mostly on the top surface side of the pile 7. This is due to the experience that it hardly occurs on the foot side of the pile 7.

Next, the sheet hanging by the sheet hanging device will be described.

(A) Sheet hanging: After the stacking of the bulk materials by the stacker 2 is completed, FIG.
As shown in the figure, the first winch 12 of the shoulder 10 and the base 1
4 lowers the boom conveyor 13 of the stacker 2 toward the top surface of the pile 7 to a height position where a line connecting the second winch 15 to the slope of the pile 7 is substantially parallel, and drives the second winch 15 to drive the second winch 15 The cable 27 is extended.

A weight (not shown) is attached to the tip of the second rope 27, and the weight is struck by a gun or the like on the road shoulder 10 on both sides of the pile 7.

The fourth winch 19 is driven and the fourth cable 28 is extended.

A weight (not shown) is attached to the tip of the fourth rope, and this is struck by a gun or the like onto the road shoulder 10 on both sides of the pile 7.

The weight is removed from the tip of the second cable 27 at the shoulder 10 and the tip of the second cable 27 and the first cable 11 of the first winch 12 are removed.
To the tip of the cable with a bracket 29 such as a hackle.
The weight is removed from the distal end of 8, and the distal end of the fourth cable 28 is connected to the distal end of the mesh sheet 17 via the metal fitting 30.

The second winch 15 is rewound to tension the first ropes 11 on both sides of the pile 7.

After the tension, the third winch 18 on both sides of the pile 7 is extended until the rear end of the mesh sheet 17 has a length that can move to half the slope, and then the fourth winch 19 is driven. The mesh sheets 17 on both sides of the pile 7 are drawn toward the top surface of the pile 7.

As a result, the mesh sheet 17 is expanded.

After the opening of the pair of left and right mesh sheets 17 is completed, the second cable of the second winch 15 and the fourth cable 28 of the fourth winch 19 are extended, and the mesh sheet 17 is landed on the pile 7.

The distal ends of the left and right mesh sheets 17 are connected to each other by connecting fittings 31.

The second cable 27 of the second winch 15 is connected to the first cable 1
Then, the fourth cable 28 is separated from the tip of the mesh sheet 17, and then the third cable 32 is rewound as appropriate to remove the slack of the mesh sheet 17.

This operation is sequentially repeated in the longitudinal direction of the pile 7 to cover the pile 7 with the mesh sheet 17 to prevent dust from being generated from the surface of the pile 7.

(A) Sheet removal: A connection fitting 3 for connecting the ends of the mesh sheet 17 to each other.
After removing the wires 31, the tip of the second cable 27 and the tip of the first cable 11 are connected by the metal fitting 29, and then the second winch 15 is rewound to tension the first cable 11. Mesh sheet 17
Is naturally slid down along the first cable 11 by its own weight, and is suspended on a pole 24 as shown in FIG.

Thereafter, the third winch 18 is wound up and the storage of the mesh sheet 17 is completed.

In the description of the present embodiment, the use of the stacker 2 as the bulk cargo handling apparatus has been described. However, the reclaimer 3 for cutting bulk materials from the pile 7 has been described.
Alternatively, it is naturally possible to use a stacker reclaimer having both functions of the stacker 2 and the reclaimer. In addition, the second winch 15 and the third winch 18 may be integrally attached to the hanger stand 22.
