Hereinafter, with reference to FIGS. 1 to 3, the operation of the raw material coal charging amount adjusting device according to an embodiment of the present invention will be described.

For the crushing of the crusher, as the raw coal 11, for example, when coal is charged into the vibrating feeder 10, the coal is transported along the charging direction as shown by the arrows inside the vibrating feeder 10.

At this time, if the coal is charged excessively to the inside of the vibration feeder 10 in a set amount or more, the excess coal hits the blocking plate 100, and the blocking plate 100 blocks the charging of raw coal.

That is, when the coal is charged excessively in the vibrating feeder 10, that is, when a lot of coal is charged above a set height from the inner bottom surface of the vibrating feeder 10, the coal is a blocking member 110 of the blocking plate 100 ).

As the blocking member 110 of the blocking plate 100 collides with coal, the blocking plate 100 overcomes the elastic force of the elastic member 220 of the charging amount adjusting device 200 while the upward direction of the blocking plate 100 ( 2 in the Y direction).

On the other hand, when the charge amount of coal is less than the set amount, the blocking plate 100 may be moved in the downward direction (Y direction in FIG. 2) of the blocking plate 100 by the elastic force of the elastic member 220. .

As the blocking plate 100 is moved in the upward or downward direction, the highest position rising prevention plate 230, the guide rod 240, and the elastic support plate 250 coupled to the upper portion of the blocking plate 100 are also blocking plates. Together with the (100) it is moved along the vertical direction of the casing (210).

As described above, the blocking plate 100 may be moved upward or downward in the blocking plate 100 as the amount of coal charged increases or decreases below a predetermined amount.

The moving distance of the blocking plate 100 may be adjusted by adjusting the elastic force of the elastic member 220 elastically supported between the upper surface of the casing 210 and the elastic support plate 250.

In addition, the movement of the blocking plate 100 may be guided by the guide member 130.

The elastic compression and elastic expansion of the elastic member 220 may be guided by the guide rod 240.

In addition, the size of the elastic force of the elastic member 220 may be adjusted by the elastic force adjusting device 260.

That is, the size of the elastic force of the elastic member 220 can be largely or smallly adjusted by adjusting the gap between the top position rising prevention plate 230 and the elastic support plate 250 by tightening or releasing the adjusting nut 263.

And, the upward movement of the blocking plate 100 may be limited by the highest position rising prevention plate 230.

That is, when the coal of the maximum loading amount more than the set amount is charged into the inside of the vibration feeder 10, the highest position rising prevention plate 230 contacts the lower surface of the casing 210 by upward movement of the blocking plate 100. As it is, the upward movement of the blocking plate 100 may be restricted.

In addition, when the top position rising prevention plate 230 is in contact with the lower surface of the casing 210 and the upward movement of the blocking plate 100 is limited, the charge amount that can be adjusted by the charge amount adjusting device 200 is exceeded. Coal is being charged.

In this case, it is possible to temporarily block the charging of coal into the inside of the vibration feeder 10 by the raw material coal blocking device 300.

That is, when a large amount of coal is charged at a time in excess of the charge amount that can be adjusted by the charge amount adjusting device 200, the touch plate 330 centers on the shaft 340 while coal is colliding with the touch plate 330 Is rotated in one direction (for example, clockwise).

When the shaft 340 is rotated by the touch plate 330 at an angle set together with the bearing unit 350, the touch bar 360 is also rotated at an angle set in one direction (eg, clockwise).

Then, when the touch bar 360 is rotated at a set angle, the touch bar 360 comes into contact with the limit switch 370.

When the limit switch 370 comes into contact with the touch bar 360, the operation cylinder 320 is operated to close the blocking gate 310 by a control unit (not shown).

As the blocking gate 310 is closed, the charging passage of coal can be blocked, thereby temporarily blocking the charging of coal.

In addition, when the overload of coal is eliminated, as the touch plate 330 is returned to the original position, the touch bar 360, the shaft 340, and the working cylinder 320 are also returned to the original position while the blocking gate ( 310) is opened, and coal is normally charged through the charging passage.

As the above-described operation is repeatedly performed, the crushing operation of coal by the crusher can be smoothly performed as the amount of coal is controlled in accordance with the size and size of the coal charged into the vibration feeder 10.
