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 literature.

Book title: Stacking Blendening Reclaiming of
Bulk Materials, Publication date: Bulk Materials
Handling series, Vol.1 (1975/77) No.5,
Edited by RH Wohlbier, published by Trans Tech
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 with 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 are transported 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 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. 1 is a transfer machine that runs on rails, and is composed of a boom 2 that rotates horizontally, a boom conveyor 3 placed along this boom 2, and a bucket wheel 4 placed at the tip of the boom 2. .
6 is a loading chute, which is installed above the boom conveyor 3. When discharging, there is a bucket wheel 4, a boom conveyor 3, a dispensing chute 7,
It is dropped onto a ground conveyor 10 via a relay chute 8 and a hopper 9. These configurations are similar to known configurations. Reference numeral 11 denotes a chute for direct delivery, the upper end of which is the same as the upper end of the chute 6 for loading.
The lower end opens into the relay chute 8 .

Reference numeral 15 denotes a tripper for supplying bulk materials from the ground conveyor 10 to the loading chute 6 or direct delivery chute 11, and has a chute 19 at its upper end. The tripper 15 has a moving device 1 installed on its legs 16.
7 and a connecting member 18, it is connected to the transfer machine 1. The tripper 15 is towed by the transfer machine 1 and transports the rail.

In FIGS. 3 and 4, one end of the connecting member 18 is fixed to a bracket 35 of the transfer machine 1 so as to be rotatable in the vertical direction, and is placed on rollers 20, 20 provided on the legs 16 of the tripper 15. . A pin rack 21 is provided on the end side of the connecting member 17. The pin rack 21 has a pin 2 between the plates 21a and 21b on both sides.
1c are arranged at predetermined intervals. The ends of the connecting members 18, 18 are connected by a connecting member 22. The rollers 20, 20 have legs 16, 16
It is placed on a connecting member 23 that connects the two. The connecting member 23 is located above the ground conveyor 10. In addition, a bracket 2 is attached to the lower part of the legs 16, 16.
5 is provided, a fixed seat 26 is placed thereon, and the moving device 1 is mounted on the fixed seat 26.
7 is listed. The moving device 17 has a pinion 28 which meshes with the pin rack 21. 30
is a pulley of the ground conveyor 10, and the connecting member 2
It is listed in 3.

The ground conveyor 10 climbs the tripper 15 from the ground, reverses itself 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 3 is operated. For loose items, use chute 7 for dispensing;
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 19 of the tripper 15 is positioned above the loading chute 6, as shown in FIG. This positioning is performed using the moving device 17. The bulk items are lifted upward by the tripper 15, thrown into the loading chute 6 from the chute 19, and dropped into the yard via the boom conveyor 3.

When performing a direct operation after the loading operation, the pinion 28 of the moving device 17 is rotated in the backward direction. As a result, the tripper 15 is guided by the connecting member 18 and retreats. As shown in Figure 2, Trippa 1
When the chute 19 of No. 5 is positioned above the direct feed chute 11, the rotation of the pinion 28 is stopped and this state is maintained using a built-in braking device. In this state, the bulk material is dropped onto the ground conveyor 10 through the bulk chute 19, the direct delivery chute 11, the relay chute 8, and the hopper 9.

When changing from direct delivery operation to loading operation, the moving device 17 is used to advance the tripper 15 to position its chute 19 above the loading chute 6. The moving device 17 maintains its state by operating a built-in braking device (not shown). Therefore, when the transfer machine 1 moves forward while rotating the boom 2, it moves forward via the connecting member 18, and the position of the chute 6 with respect to the loading chute 6 does not change.

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.

If the chute 19 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.

In contrast, in the present invention, the direct delivery chute 10 is arranged in parallel behind the dispensing chute 7, and the entrance of the relay chute 8 is only enlarged, and the transfer machine 1 is not changed significantly. The height of the transfer device 1 and the tripper 15 can be reduced. Since the height of the tripper 15 can be reduced, the length can be shortened and the usable area of the yard can be increased.

Further, since the connecting member 18 is vertically movable and its tip is supported by a roller 20 installed on the leg 16 of the tripper 15, it can follow well even if the track on the ground is curved. Furthermore, the connecting member 18 only needs to have strength in the running direction, and can be configured simply. Furthermore, since the tripper 15 is moved relative to this connecting member, the configuration can be simplified.

The moving device 17 can use various means such as a rack type. Further, the transfer device 17 is the transfer device 1
Alternatively, the transfer machine 1 and the tripper 15 may be provided.
It may also be installed on a trolley that runs on rails between the two. The direct delivery chute 11 does not need to be fixed to the boom 2.

〔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. Further, the configuration of the connecting member and the means for moving the tripper can be simplified.
