EXAMPLE

4A is a perspective view and a functional view showing a state when the belt backside fall detection device according to the present invention is installed in the belt backside and there is no fallout entry.

As shown in FIG. 4A, the fall detection device according to the present invention located on the rear surface of the belt 2 is operated without an ore being loaded on the belt 2, or when the belt 2 is stopped. As shown in the figure, the rotating pipe 16 to which the plurality of rotating bars 17 are welded is stopped by the central axis rotating bar 18, and in particular with the left and right detecting light sensors 24 and 24 '. When the through holes 26 of the partitions 27 coincide with each other, the belt conveyor equipment is in a normal state without a signal.

4B is a perspective view and a functional view showing a state when the belt backside fall detection device according to the present invention is installed on the belt backside and there is a fallout entrance.

As shown in FIG. 4B, when the ore 6 is loaded on the return belt 2, the ore 6 is formed by the falling-light inlet 8 formed of a pair of guide plates 7 and 7 ′ formed in a Y shape. When the ore is introduced to guide the ore 6 to the light extraction unit 9 and a large amount of ore 6 is concentrated, as shown in the partially enlarged view of FIG. 4B, the central axis rotating bar 18 is placed on the ore. As the interference hole rotates, the through hole 26 of the partition 27 in the central portion of the rotary pipe 16 also rotates to move the through hole 26 of the partition 27. As a result, the optical signals of the left and right detection light sensors 24 and 24 'are intercepted to each other to block electrical signals, thereby stopping the belt conveyor.

When the ore 6 on the rear surface of the return belt 2 is processed, the rotary pipe 16 is returned to its original position by the central axis rotation bar 18, and the belt conveyor automatically returns to its normal state.

In the belt backside fall detection device according to the present invention, the ore is loaded on the belt backside due to the meandering of the belt by flipping and knitting, thereby preventing the occurrence of overload due to raw light loss and a large amount of accumulated light. It can prevent the occurrence early to maximize the operation rate of the belt conveyor, prevent the loss of manpower and overload of the work handling the fall light, and minimize the fall light to prevent environmental pollution.
