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

When raw coal 11, for example, coal is charged into the vibration feeder 10 for crushing the crusher, the coal is transported along the charging direction as an arrow inside the vibration feeder 10.

At this time, when the coal is excessively charged into the vibration feeder 10 more than the set amount, the excess coal hits the blocking plate 100, the blocking plate 100 to block the charging of the raw coal.

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

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 ( In the Y direction of FIG. 2).

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

As the blocking plate 100 is moved upward or downward, the maximum 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 blocked. It is moved along the vertical direction of the casing 210 with the (100).

As such, the blocking plate 100 may be moved upward or downward of the blocking plate 100 as the amount of coal is charged more than the set amount or less than the set 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, by tightening or releasing the adjusting nut 263, the size of the elastic force of the elastic member 220 may be large or small by adjusting the distance between the highest position preventing prevention plate 230 and the elastic support plate 250.

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

That is, when the maximum amount of coal more than the set amount is charged into the vibrating feeder 10, the highest position preventing prevention plate 230 contacts the bottom surface of the casing 210 by the upward movement of the blocking plate 100. While the upward movement of the blocking plate 100 may be limited.

In addition, when the maximum position rising prevention plate 230 is in contact with the bottom surface of the casing 210 to limit the upward movement of the blocking plate 100, the amount of charge that can be adjusted by the charging amount adjusting device 200 exceeds Coal is charged.

In this case, the charging of coal into the vibration feeder 10 may be temporarily blocked by the raw coal charging blocker 300.

That is, when a large amount of coal is charged at one time in excess of the amount of charge that can be adjusted by the charging amount adjusting device 200, the coal is hit by the touch plate 330 and the touch plate 330 is centered on the shaft 340. Rotate in one direction (eg clockwise).

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

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 is in contact with the touch bar 360, the operation cylinder 320 is operated to close the blocking gate 310 by a controller (not shown).

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

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

As the above operation is repeatedly performed, the amount of coal is controlled in accordance with the particle size and size of the coal charged into the vibrating feeder 10, thereby smoothly crushing the coal by the crusher.
