Abstract

PURPOSE:To provide a coal expelling device not obstructing a mining device moving in a yard, protected by retaining walls, and capable of transferring any coal from both sides of the retaining walls by excavating a ditch opened upward inside the retaining walls and providing an expelling conveyor within said ditch. CONSTITUTION:In a device expelling coal C piled in heaps between retaining walls 1 provided in parallel with each other while forcing a mining device 11 to move, a ditch 1a is excavated opened upward within said retaining walls 1, an expelling conveyor 2 is arranged inside said ditch 1a, and coal taken by the device 11 into it is transferred onto the conveyor 2 and expelled to the end parts of the retaining walls 1. Namely, the conveyor does not obstruct the mining device 11 getting about inside the yard since said conveyor 2 is provided within the retaining walls, so that any damage caused by the mining device is not only prevented but also any coal can be thrown into the retaining walls from both sides of said walls. Accordingly, upon mining coal piled in heaps forming plural rows, the expelling conveyor is proper to be provided only on the walls of alternate rows, enabling installation and operation cost to be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coal dispensing device in a call center, that is, a coal storage and recommendation base.

In recent years, coal has been reevaluated as an alternative to oil energy, and there are plans to establish a national call center, and there is a need to solve environmental issues, land issues, etc., and develop an economical call center.

Conventionally, in order to meet the above requirements, coal piled up between retaining walls installed side by side was moved to coal mining equipment as appropriate and taken in one by one. There was something that was transferred to a conveyor and delivered to the end of the call center.

However, as mentioned above, since the unloading conveyor was installed on the side of the retaining wall, it not only has the drawback that it obstructs the movement of the coal mining equipment and is prone to breakage, but it also has the disadvantage that the above-mentioned wall (m) has three or more walls. In large-scale call centers where multiple rows of coal piles are formed, a delivery conveyor must be installed for each retaining wall or on both sides of the retaining wall, and construction and transport However, there were disadvantages such as high cost, complicated dispensing work, and low efficiency.

The present invention has been made to solve the above-mentioned drawbacks.
The purpose of this is to create a groove with an open top inside the retaining wall, and install the delivery conveyor in this groove so that it does not interfere with the coal mining equipment moving within the yard and is protected by the retaining wall. This allows relocation work to be carried out from both sides of the retaining wall.
We would like to offer a coal dispensing device for call centers that is inexpensive and highly efficient.

An embodiment of the present invention will be described below with reference to the drawings.

In Fig. 1, 1 is a retaining wall, for example 700 to 8
It has a length of about 00 meters, and I has a length of about 50 meters.
II Interval t-! . . . Two or more coals are installed side by side in a call center yard or two or more in a dug-out yard, and coal C is stored in piles on both retaining walls. ing. In at least one of the left and right retaining walls 1, a groove 1a which is open at the top is longitudinally formed, and a delivery conveyor 2 is installed in the groove 1a.

As is clear from FIG. 2, a rail 3 is laid on the top surface of the retaining wall 1, on which wheels 5 rotated by a moving motor 4 roll, and a moving beam 6 is constructed so as to move in parallel along the retaining wall 1 between both retaining walls 1. Two rails 7 are laid on the movable beam 6, and a bogie 9 is mounted on it so as to be freely movable via 111 wheels 8 which are rotationally driven by a suitable drive motor (not shown). There is. An hk turntable 10 is rotatably mounted on the trolley 9, and is turned left and right by a turning motor (not shown). A coal mining apparatus body 11 is fixedly mounted on the turning table 10, and the base of the collecting conveyor arm 12 is pivoted 112a. The collection conveyor arm 12 is also supported by first and second lift arms 13a, 131+, and is operable to be raised and raised from the first and second sills-Il, 4a, 141+j.

A collection conveyor 15 consisting of a rubber conveyor belt is attached to the collection conveyor 19 and 12, and its two sides are configured to move one angle in the direction of arrow A in FIG. ing.

A scraping cutter 16 having a large number of scraping claws IGa is installed at the tip of the collecting conveyor 15, and is rotated by an oil motor 17 to partially break up the piled up coal C and move it to the collecting conveyor. 15.

Pivot joint 12a of the coal mining device, that is, the extraction conveyor arm 12
is located approximately at the center of the height of the pile of coal or further above this, and each cylinder 14a.

141), the collecting conveyor 15 is raised and the scraping cutter 16 at the tip is positioned at an appropriate location on the pile to collect the coal C, and at this time, the turning table 10 is turned as necessary. It is also possible to collect the samples while appropriately shaking the collection conveyor 15 left and right.

In this way, the sampling conveyor 15 of the coal mining equipment is constantly making upward and downward vertical and rotating movements (1), and since the sampling conveyor 15 of this embodiment is made of the flexible conveyor belt made of rubber as described above, it is It is lightweight and can perform the operations mentioned above smoothly and quickly.

As shown in FIG. 2, a moving beam conveyor 19 is disposed inside the moving beam 6, and a conveyor 19 for the moving beam is disposed inside the moving beam 6.
Coal C collected by 5 is dropped from the position of the pivot portion 12a. The conveyor 19 extends to the end of the moving beam 6 and faces the groove 1aJ2 of the catch wall 1. Note that the conveyor 19 may be placed outside and on the side of the moving beam 6.

Referring again to FIG. 1, the retaining wall 1"2 is connected to the
L-ya 21 has been constructed and covers the pile of coal C. A receiving side belt conveyor 22 is arranged at the top of the shed 21, and a tripper 23 drops the coal C into it and piles it up. 24 is a cover for the conveyor 19 and the like.

Since the present embodiment is constructed as described above, when discharging the piled-up coal C, the movable beam 6 and the cart 9 are moved to appropriate positions, the cylinders 14g and 1413 are expanded and contracted, and the collection conveyor 15 is moved. Raise one side and take in coal C from the second part of the pile.

The coal C taken in by the sampling conveyor 15 is dropped into the moving beam conveyor 19''2-2 from its base end pivoting portion 12a, is carried by the conveyor 19 to the end of the moving beam 6, and is placed on the discharging conveyor 2. and is delivered to the end of the retaining wall 1. The collection conveyor 15 includes each cylinder 14a,
``1.411'', it is operated in two parts to raise and lower, and also to rotate by a turning motor,
By appropriately combining these operations and selectively moving the trolley 9, moving beam 6, etc., it is possible to sequentially take in the J, S, 111 from the 142nd direction toward the lower J without collapsing it. I can do it.

Since the present invention is installed within the retaining wall of the collection conveyor as shown in [U], there is no IJC that would obstruct the coal mining equipment moving around in the yard, and therefore there is no possibility of damage caused by the coal mining equipment. In addition, since it is possible to input coal from both sides of the retaining wall, when mining coal from multiple rows of piles, it is only necessary to install a collection conveyor on the thermal retaining wall, which can reduce equipment and operating costs. There is an effect.
