Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an apparatus for loading bulk materials such as coal sent by a belt conveyor into a yard, etc., and for scraping and discharging the bulk materials from a yard, etc. It is related to.

[Background of the invention]

A device that loads bulk materials such as coal sent by a belt conveyor into a yard is called a stacker. Also, a device that scrapes up loose materials piled up in a yard and delivers them to a belt conveyor is called a reclaimer.

The present invention relates to an apparatus having this loading function and unloading function.

This device can be used as a stacker or as a reclaimer, and can also be used as a belt conveyor to bypass bulk materials sent by the belt conveyor and send them to the next yard without loading them into the yard. There are three types of direct shipping.

A device having the three functions of loading, unloading, and direct delivery is shown in the following document.

Book title: Stacking Blendening Reclaiming of Bulk Materials
Materials), issue number; Bulk Materials Handling
Volume 1 of the series (1975/77) No. 5, published;
Trans Tech Publications (Trans
Teach Publications) This type of device is roughly divided into three types, as shown on page 689 of the above-mentioned document. That is, it consists of a tripper, a trailer conveyor, and a transfer machine (stack/reclaimer) having bucket wheels. The three components are arranged in the order of the transfer machine, trailer conveyor, and tripper in the direction of travel, are connected in sequence, and run as one on the rail. A ground conveyor is installed along the rail.

The transfer machine has a bucket wheel at the tip of a horizontally rotating boom. At the time of discharging, the bucket wheel is rotated, and the scraped loose materials are conveyed to the base of the boom via a conveyor placed on the boom, and then dropped onto a ground conveyor via a chute or hopper for discharging. When loading, the boom conveyor is reversed and the boom tip drops into the yard. The bulk material is fed to the boom conveyor via an above ground conveyor, tripper and trailer conveyor.

The tripper lifts the ground conveyor diagonally upward, and has a two-pronged chute at its diagonally upper end, as shown on page 29 of the above-mentioned document. One outlet of the two-pronged chute opens onto the conveyor of the trailer conveyor, and the other outlet opens onto the ground conveyor. The forked chute has a valve to select either outlet.

The trailer conveyor feeds the bulk material fed from the two-pronged chute of the tripper onto the conveyor of the boom of the transfer machine.

During loading, the outlet of the tripper's two-pronged chute is switched to the trailer conveyor side. Loose materials on the above-ground conveyor are transported by trippa, two-pronged chute,
It is dropped onto the boom conveyor of the transfer machine via the trailer conveyor.

During direct delivery, the outlet of the two-pronged chute of the tripper is switched to the ground conveyor side. The bulk materials on the ground conveyor are dropped onto the ground conveyor again via the tripper and the two-pronged chute, and are carried downstream.

In this way, the conventional device consists of three devices,
Equipment is becoming more expensive. Furthermore, since it consists of three devices, the length in the direction of movement is large, which shortens the length of the yard in which bulk materials are stored, reducing the usable area of the yard.

[Purpose of the invention]

An object of the present invention is to provide a device that is inexpensive and short in length.

[Summary of the invention]

The present invention provides a transfer machine with a direct delivery chute used for direct delivery on the same horizontal plane as the loading chute of the transfer machine, a tripper that can be directly supplied to the two chutes, and a gap between the transfer machine and the tripper. The load from the tripper is supplied to the loading chute or direct delivery chute by controlling the distance.

[Embodiments of the invention]

The present invention will be explained below with reference to an embodiment shown in the drawings.

In FIG. 1, numeral 1 is a transfer machine that runs on rails, and includes a boom 2 that is horizontally swingable on a running body that can run on the ground, a boom conveyor 3 arranged along this boom 2, and a boom conveyor 3 that is arranged along the boom 2. It consists of a bucket wheel 4 placed at the tip of a bucket wheel 2, etc. 6 is a loading chute, which is installed above the boom conveyor 3. At the time of delivery, it is dropped onto the ground conveyor 10 via the bucket wheel 4, boom conveyor 3, direct delivery chute 11, relay chute 8, and hopper 9. Said direct delivery chute 1
1 is the same as the upper end of the loading chute 6.

Reference numeral 15 denotes a tripper for supplying bulk materials from the ground conveyor 10 to the loading chute 6 or the direct delivery chute 11, which consists of a guide part that gradually raises the ground conveyor 10 and a chute 16 provided at the upper end of this guide part. . The conveyance direction of loose materials by the ground conveyor 10 is from right to left in FIG. The ground conveyor 10 raised by the guide portion of the hopper 15 passes through the chute 16, then descends to near the ground and passes below the hopper 9. The tripper 15 and the transfer machine 1 can travel in the direction in which the ground conveyor 10 is arranged.

In FIG. 2, reference numeral 17 denotes an insertion/extraction device for moving the tripper 15 back and forth with respect to the transfer machine 1. The insertion/extraction device 17 is installed between the leg part 18 of the tripper 15 and the leg part 19 of the transfer machine 1, and includes a horizontal member 20 that protrudes from the leg part 19 of the transfer machine 1 in the rear horizontal direction, It consists of a piston-cylinder device 21 installed between the end of the horizontal member 20 and the leg 18 of the tripper 15. piston·
The cylinder device 21 is fixed to the horizontal member 20 and the legs 18. Since the tripper 15 is connected by the insertion/extraction device, it is towed by the transfer machine 1.

22 and 23 are respective running wheels.

The ground conveyor 10 climbs the tripper 15 from the ground, turns around at the pulley 31, passes through pulleys 32 and 30, and passes below the hopper 9 of the transfer machine 1.

In this configuration, when performing a dispensing operation, the bucket wheel 4 is rotated and the boom conveyor is operated. The bulk materials in pile 35 are transported by 4 bucket wheels, 3 boom conveyors, and 1 direct delivery chute.
1. It passes through a relay chute 8 and a hopper 9 and is dropped onto a ground conveyor 10.

When carrying out a loading operation, the chute 16 of the tripper 15 is positioned above the loading chute 6, as shown by the broken line in FIG. This positioning is performed using the insertion/extraction device 17. That is, the rod of the piston/cylinder device 20 is contracted and the tripper 15 is advanced from the position shown by the solid line to the position shown by the broken line.

Accordingly, the bulk materials on the ground are lifted upward by the tripper 15, thrown into the loading chute 6 from the chute 16, passed through the boom conveyor 3, and are dropped into the yard through the section of the tip pulley 14.

When performing direct delivery operation after loading operation, operate the piston/cylinder device 21 to release the tripper 1.
5, and move chute 1 as shown by the solid line in Figure 1.
6 is positioned above the direct delivery chute 11. Also, depending on the horizontal rotation angle of the boom 2, the direct feed chute 11 is not located below the chute 16, so the direction of the boom 2 is made to match the traveling direction of the transfer machine 1, and the direct feed and interlock operation of the ground conveyor 10 are performed. Do this. In this state, the bulk materials are dropped onto the ground conveyor 10 through the chute 16, the direct feed chute 11, the relay chute 8, and the hopper 9.

As described above, since the trailer conveyor is no longer necessary, the apparatus can be constructed at low cost.

Furthermore, since there is no trailer conveyor, the length of the device can be shortened and the usable area of the yard can be increased.

Note that if the chute 16 of the tripper 15 is a two-pronged chute, it is not necessary to move the tripper 15 back and forth with respect to the transfer machine 1, but since a two-pronged chute requires a certain height, the tripper The height up to the chute 15 becomes higher, and the height of the transfer machine 1 must also be increased, which requires a new design. Furthermore, as the height increases, the length of the tripper 15 also increases.

On the other hand, in the present invention, the direct delivery chute 11 is arranged in parallel behind the unloading chute 6, and is only provided so that loose items can fall to the relay chute 8 during direct transport and unloading. No changes. The height of the transfer machine 1 and the tripper 15 can be reduced. Since the height of the tripper 15 can be reduced, the length can also be shortened, and the usable area of the yard can be increased.

The means for moving the tripper 15 may be an electric pin rack type or a hydraulic cylinder type.

〔Effect of the invention〕

As described above, according to the present invention, since a trailer conveyor is not required, the cost can be reduced and the usable area of the yard can be increased.
