Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in an ore storage yard in which relatively large grains and lumps such as coal, ore, and earth and sand are stored outdoors in open piles.

Traditionally, bulk materials such as coal, ore, and earth and sand have been stored and covered outdoors in open piles, where they are exposed to wind and rain and are relatively unlikely to change in quality. .

In this case, a dozer is usually used for loading and discharging the accumulated material, and the discharging is carried out by lifting and raking the accumulated material while spreading it out.

However, with such tree planting and removal, it is difficult to greatly increase h'1-1-gem, and it is difficult to make effective use of the area.
Not only that, but when the bulldozer was used to spread or scrape the area, a large amount of dust was generated, which polluted the surrounding environment.

For this reason, it is called a paddle feeder or rotary discharge 11-, which is surrounded by embankments, retaining walls, etc., and has four parts with an open top, and has an inner arc-shaped arm that is driven to rotate at the bottom. An ore storage yard is provided in which a device and a moving chute are installed, and the stored material is sequentially transferred from the bottom onto the moving chute by a distance of 0-J' (4 m) using a paddle feeder.

However, even in a storage yard with this structure, although the efficiency of unloading work is slightly improved compared to the above-mentioned bulldozer, it is necessary to push out the stored materials with a bulldozer during loading work, and when unloading In this method, it is necessary to scrape up accumulated material outside the drive range of the arm of the paddle feeder, which is inefficient and also leaves the problem of dust unsolved.

This invention was made to solve the technical problems of the conventional ore storage V-do as described above, and the purpose is to automatically load and unload stored minerals. It is an object of the present invention to provide an ore storage yard that can reduce and suppress dust generation, especially during loading work.

In order to achieve this object, the present invention is designed to be installed in a relatively large-scale outdoor ore storage yard along the longitudinal direction of a recess formed by buried earth or a retaining wall, and to be able to expand and contract at both ends. a movable shuttle conveyor device to which telescopic shoes 1 to 1 are attached; a linear dispensing device b' disposed at the bottom of the recess opposite to the shuttle conveyor Kn; A horizontally movable screw conveyor device extending in one direction perpendicular to the direction of It is characterized by (-7).

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figures 1 to 3 show the storage of ore according to the present invention.
This is an example.

The ore storage yard (not shown in the figure) has a recess 12 surrounded by an embankment 10 in a substantially elongated shape, and a granular or lump-like stored material 14 such as ore, coal, etc. is stored in the recess 12. It is meant to accommodate people.

The ore storage yard shown in the figure is different from the conventional one of this type.
(, has the following characteristics).

On top of a plurality of concrete or steel piers 16 erected along the longitudinal axis of the recess 12, the side ends are slightly outward from the piers 16. A protruding garter 17 is fixedly installed to construct a hollow gear rally 18, and a driving device such as an electric motor is used to move a pair of parallel rails 20 installed on the garter 17 in the gear rally 18. Accordingly, an elongated shuttle conveyor device 22 that runs left and right in the longitudinal direction within the recess 12 is disposed, and at both ends of the shuttle conveyor device 22 in the longitudinal direction, hollow bodies having different diameters are combined in layers and wire lobes are arranged. Telescopic chutes 24, which can be expanded and contracted by hanging them from a cable or the like, are attached to each of them.

Further, at the bottom of the recess 12, there is a discharge bit 26 which is hollow inside and open at the upper end, and is disposed along the longitudinal axis so as to face the shuttle conveyor device 22.
An inverted ■-shaped cover 28 is disposed above the upper end opening of the ejection bit 26 at a predetermined distance, and a pair of straight slit-shaped slits are formed between the upper end of the ejection bit 26 and the lower end of the cover 28. While forming the discharge port 30,
Inside the ejection bit 26 is an ejection bell 32 disposed such that one end thereof protrudes outside the recess 12;
It travels on the 1-output conveyor 32 or on the rail suspended from the cover 28, and the arc-shaped arm body projects outward from the slit-like discharge port 30, and the stored material 14 in the vicinity is transported to the discharge pits 1 to 2G. The rotating type dispensing device 34 (
Badol feeder or rotary dimechi 1 fuge 1
/- is called C. ) are installed, and these constitute a discharge device 36 for discharging 1/l of the stored material out of the recess 12.

In this case, the inverted V-shaped cover 28 not only forms the slit-shaped discharge 30 as described above, but also prevents the WE of the storage section 171 from coming into contact with the rotary dispensing device @34, and Mounted 3G j: (j 1Fii space is secured.

Furthermore, in the direction in which the conveyor equipment 22 is mounted, a pair of screw conveyor devices 38 having approximately the same configuration are disposed. The conveyor device 38 has a first rail 4O installed on the outward protrusion of the garter 17 on the pier 1G, and a second rail 42 installed on the upper end surface of the embankment 10. In between, a traveling garter 44 installed to straddle the storage material 14 and a garter traveling device 46 can move along the longitudinal direction so as to cover approximately 1/2 of the area of the recess 12. A screw conveyor 48 equipped with a rotatably driven screw auger is suspended below the traveling garter 44 by a wire 1"-pipe 50, and can be moved up to any position by a hoisting device 52.

The screw conveyor 48 is arranged in single or plural units according to the capacity of loading and unloading, and is driven by a screw drive device 54 in the direction of the embankment 10 during loading and in the direction of the central unloading device 36 during unloading. In, the reservoir 14
are driven to transport each.

On the other hand, 7z of the movement range of the above-mentioned seat 11 conveyor 22
This shuttle conveyor device 22 is located approximately in the center.
A carry-in conveyor 56 and a chute 5 supplying stored material 14 to
8 are arranged.

In order to transport the stored material 14 to the ore storage yard having the above-mentioned structure, first, the stored material 14 is transferred to the conveyor container 22 of the shaft 1 via the transport container 756 and the chute 58, and then transferred to the transport surface. Move the upper part to the right and place the C1 reservoir 14 on the longitudinal axis of the recess 12 through the telescopic seat 24 in the shape of a mountain inclined at an angle of repose (θ). Get piled up soil.

In this case, the above-mentioned Teresu pick 1-1-24 is gradually returned upward depending on the height of the pile.

Then, when j(1vi) of the accumulated material 14 has progressed to a certain extent, the screw conveyor 48 is moved while the J garter 44 is horizontally moved C by the drive of the garter traveling device 46. The stored material 14 is pushed out toward the embankment 10 side by rotational driving, and is rammed (=lf) to a predetermined height.

In this case, the telescope 1 pickshoot 24 and the screw conveyor device 38 can be operated in conjunction with each other, or can be operated separately.

On the other hand, when dispensing, first the rotary dispensing device 3
4, scrape up the stored material 14 from the slit-shaped discharge port 30, and force it upstream of the conveyor conveyor 32.The part where it falls due to gravity is the part A shown in Fig. In the parts (B, C), while horizontally moving the traveling garter 41, the screw conveyor 48 is rotated so that the accumulated material 14 is directed toward the center, and the stored material 14 is scraped up and supplied to the rotary dispensing device 34 and discharged onto the discharge conveyor 32. Demotsu C is carried out.

In this case, when discharging portion C of the stored material 14, the inclination angle of the embankment 10 inward is determined by the repose angle (θ) of the stored material 14.
It is preferable to set the slope U to be approximately the same as or slightly larger than that, so that accumulated materials will not remain on the slope.

Now, the ore storage yard having the above-mentioned configuration is extremely efficient in that it can be stowed in an average condition without requiring any manual labor, compared to the conventional stowage using a bulldozer. Because the materials are stacked while expanding and contracting, dust generation can be greatly reduced.

Also, the screw conveyor device 38
By using this, all of the stored material 14 can be dispensed almost completely automatically.

A3, 10th embodiment, surround the recess 12 #3''L'?J
Although the two embankments 10 are shown as having 14 parts, it is of course possible to use them as retaining walls made of concrete or the like.

Further, depending on the longitudinal length of the recess 12 for storing the stored material 14, it is possible to install a plurality of the shuttle conveyor devices 22 in series, and also in the width direction. Each device in the configuration (Share I ~ Le conveyor device 2
2. Of course, it is possible to install a plurality of "screws" (conveyor devices 38, etc.) in parallel.

The ore storage yard according to the present invention, which has been explained in detail in the embodiments above, automatically performs the dumping and discharging of the stored material, and reduces the generation of dust during the loading operation. can also be significantly suppressed.
