The operation of the present invention configured as described above will be described with reference to FIG.

When the metal and the non-ferrous metal is moved to the belt 110 of the belt conveyor 100 along with the raw coal, the mask metal detector 10 detects this and stops the belt conveyor 100 by an electrical action.

When the belt conveyor 100 is stopped and the movement of the belt 110 is stopped, the apparatus is operated to remove foreign substances.

First, the belt 110 is raised and lowered, and as the operation cylinder 46 installed on the vertical member 40 is contracted and operated, the wire 44 connected to the tip of the piston rod of the operation cylinder 46 is pulled and pulley ( While passing through the wire 44, the tip of the wire 44 is pulled upward, and the lifting roll 42 connected to the tip of the wire 44 rises along the guide hole 41 of the vertical member 40.

As the lifting roll 42 is lifted from the bottom of the belt 110, the belt 110 is pushed up by the lifting roll 42 or lifted to a certain height.

In this way, when the belt 110 is lifted by the lifting roll 42, the belt 110 is almost horizontally unfolded.

When the belt 110 is lifted as described above, the driving motor 26 installed in the base frame 20 is operated to move the moving cart 22.

When the drive motor 26 is operated, the drive sprocket wheel 23 installed on the rotation shaft of the drive motor 26 is rotated, and the chain 25 connecting the drive sprocket wheel 23 and the driven sprocket wheel 24 is moved and the chain moves. The moving cart 22 connected to the 25 is moved to the upper portion of the belt 110 along the guide rail 21 installed in the base frame 20.

When the vertical shaft 30 installed in the lower portion of the mobile trolley 22 is positioned above the belt 110 according to the movement of the mobile trolley 22, the driving motor 26 is stopped and the operating motor installed on the vertical shaft 30. Power is applied to the 36 and the electromagnet 31 to actuate both components.

When the operating motor 36 is driven, power is transmitted through the gear group so that the shaft 35 is lowered in the vertical axis 30. As the shaft 35 descends, the electromagnet 31 installed at the tip of the shaft 35 moves downward to approach the raw coal loaded on the belt 110.

In addition, the bucket 32 connected to the shaft 35 via the link member 34 is opened to both sides by being pushed outward by the link member 34 as the shaft 35 descends.

As described above, the bucket 32 opens to both sides, and the electromagnet 31 descends and moves to the raw coal loaded on the belt 110, so that the magnetic foreign matter contained in the raw coal is attached to the electromagnet 31.

In addition, the non-ferrous metal that does not adhere to the electromagnet 31 is separated as the bucket 32 is pinched.

That is, when driving the operating motor 36 in the reverse direction in the metal attached to the electromagnet 31 as described above, the shaft 35 is moved up from the vertical axis 30 to pull up the foreign matter stuck to the electromagnet 31. In addition, as the link member 34 installed on the shaft 35 is pulled, the bucket 32 is retracted, and the hook bar 33 installed at the tip of the bucket 32 penetrates into the raw coal loaded on the belt 110. They cross and retract.

Therefore, the non-ferrous metal is collected in the hook bar 33 of the bucket 32 to be retracted and is in a state of being caught inside the hook bar 33.

In this state, when the operation cylinder 46 is extended and operated again, the rising roll connected to the wire 44 descends to return the belt 110 to its original position. As the belt 110 is lowered, the raw coal loaded on the belt 110 is Escape through the hook bar 33 is placed on the belt 110 as it is and is separated from the raw coal in a state that only the foreign matter attached to the electromagnet 31 or hanging on the hook bar 33.

When the belt 110 is completely lowered, the driving motor 26 is operated to move the moving cart 22 to the outside of the bat to position the vertical shaft 30 on the collecting box 50 located outside the belt 110. When the pre-operation motor 36 is driven to open the bucket 32 and cut off the power supply to the electromagnet 31, the separated foreign matter is collected into the collection box (50).

As described above, according to the foreign material removing apparatus according to the present invention, if a foreign material (metal iron piece, non-metal material) is detected by the metal detector while transporting the raw coal using the belt conveyor, the device of the present invention operates to remove the foreign material. This prevents damage to the belt conveyor beforehand, which contributes to stable operation.
