The transfer belt 22 is moved in a state in which a foreign material 28 including iron pieces is mixed with a raw material 26 such as coal or iron ore.

As shown in Figures 1 to 5, the device for preventing damage to the conveying belt 22 according to an embodiment of the present invention, the foreign material contained in the conveying belt 22 for conveying the raw material 26 ( 28 is a foreign body detector 1 for sensing the foreign object, the guide unit 30 and the foreign body sensor 1 is installed on the guide unit 30 to move the foreign matter sensor 1 on the guide unit 30 ).

As shown in Figures 1 to 3, the foreign material detector 1 is a body member 10 is provided with a sensor unit (not shown) for detecting the foreign material 28 made of a metal material, the body member 10 It includes a support member 12 for supporting both sides of the.

The foreign material detector 1 may use various kinds of sensors within the technical concept of detecting the foreign material 28 of the metal component included in the raw material 26.

The foreign object detector 1 according to an embodiment measures the change in the magnetic field that changes when the foreign material 28, which is a metal component, approaches and detects the presence of the foreign material 28.

The sensor unit may be installed in the body member 10 installed across the conveying belt 22, and may be variously modified, such as installed in the body member 10 and the support member 12.

As shown in FIG. 3 and FIG. 5, a driving unit 40 for moving the foreign object sensor 1 is provided below the support member 12. The driving unit 40 includes a roller unit 42 installed in the guide unit 30 and a driving motor 46 for driving the roller unit 42.

The roller portion 42 is rotatably installed on the bracket 14 fixed to the lower side of the support member 12, and a driving motor 46 is installed on one side of the roller portion 42 to provide the roller portion 42. Rotate

A transmission 44 is installed between the drive motor 46 and the roller portion 42 to transmit the power of the drive motor 46 to the roller portion 42.

The roller unit 42 and the driving motor 46 may be installed on the same axis, and may be installed on different axes, and may be variously modified, such as being connected to gears.

3 and 4, the roller-shaped roller portion 42 is inserted into the guide groove 32 formed inside the guide portion 30 is moved. The guide part 30 may be deformed into various shapes within the technical spirit of guiding the movement of the roller part 42.

The foreign material sensor 1 having the roller part 42 detects the position of the foreign material 28 included in the raw material 26 while moving along the guide part 30.

The sensor member 50 for detecting the movement of the roller 42 is installed at both ends of the guide groove 32, and is operated by the contact of the roller 42 to transmit the measurement signal to the controller 60.
