1 to 3, a light blocking device 1 for a belt conveyor according to an embodiment of the present invention includes a supporting portion 30 fixed to a discharge hopper 12 of a continuous unloading machine 10, A movable frame 40 which is vertically movable along the supporting portion 30 and on which a roller member 46 is rotatably installed on the lower side facing the belt member 21, And an elongated member 60 of an elastic material which is detachably attached to the mounting frame 50 and extends in the direction toward the belt member 21. [

A continuous type unloading machine 10 unloading a conveyed matter 15 loaded on a ship is provided with a supply belt conveyor 11 for conveying the conveyed material 15 and a conveying object 15 (Not shown).

The discharge hopper 12 can be formed in various shapes within the technical concept of guiding the drop of the conveyed material 15 moved along the supply belt conveyor 11. [ The discharge hopper 12 according to one embodiment is bent into the letter "a " so as to move as the continuous unloading machine 10, and the first side wall 13 and the second side wall 14 of the discharge hopper 12 are moved downward In the width direction W of the belt member 21 provided at the front side.

The belt conveyor 20 positioned below the discharge hopper 12 transfers the conveyed material 15 falling through the discharge hopper 12 of the continuous unloading machine 10 to a post-process.

The supporting portion 30 may be fixed to the discharge hopper 12 of the continuous unloading machine 10 and may be deformed into various shapes within the technical idea of guiding the vertical movement of the moving frame 40. [ The supporting part 30 according to an embodiment is formed in an opened shape on the upper side and has an inner space 32 in which the moving frame 40 can be moved up and down and supports both sides of the moving frame 40.

The support portion 30 according to an embodiment is formed in a " C "shape in longitudinal section, and is provided on both sides of the first sidewall 13 and on both sides of the second sidewall 14, respectively. The movable frame 40 is inserted into the inner space 32 of the support portion 30 through the upper side of the support portion 30 because the upper side of the support portion 30 is open.

The movable frame 40 is movable up and down along the support portion 30 and can be deformed into various shapes within a technical idea in which a roller member 46 is rotatably installed on the lower side facing the belt member 21 . The movable frame 40 according to one embodiment includes a moving body 42, a supporting member 44, a roller member 46, and a central member 48. [

The moving body 42 extends in the longitudinal direction D of the rail and is supported on both sides of the supporting portion 30. [ The support member 44 extends downward from both sides of the moving body 42, and a roller member 46 is rotatably installed. Therefore, the movable body 42 and the receiving member 44 are formed in a "C" shape in which the opened portion faces downward. The center member 48 is formed in a plate shape and extends downward from the moving body 42 toward the mounting frame 50 and hinged to the mounting frame 50. The roller member 46 is rotated in contact with the belt member 21 or the conveyed article 15 moved along the belt member 21. [

The mounting frame 50 is also formed in a plate shape and is rotatably installed on the lower side of the movable frame 40. In the state in which the mounting frame 50 and the center member 48 of the moving frame 40 are opposed to each other and the hinge-like rotary connection portion 70 is in contact with the center member 48 and the mounting frame 50, (72) is fastened to the rotary connector (70). Accordingly, the mounting frame 50 and the elongated member 60 can be rotated about the rotation connecting portion 70. The extension member 60 is inserted into the mounting groove 52 of the mounting frame 50 and is mounted on the mounting frame 50. The mounting frame 50 is provided with a mounting groove 52 in which the extension member 60 is inserted, .

The extension member (60) is detachably mounted to the mounting frame (50) and extends in the direction toward the belt member (21). The extension member 60 includes an elastic material such as rubber so that damage to the belt member 21 can be minimized when the extension member 60 contacts the belt member 21 of the belt conveyor 20. [ The extending member 60 is formed in a rectangular plate shape and is fixed to the fastening member 72 in a state of being in contact with the mounting frame 50. The extension members 60 are provided on both sides in the width direction W of the belt member 21 and are provided below the first side wall 13 and the second side wall 14 of the discharge hopper 12 respectively.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an operation of a light blocking device 1 for a belt conveyor according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

A plurality of continuous unloading units 10 are installed on the upper side of the belt conveyor 20 for conveying the conveyed objects 15 to the yard. The conveyed material 15 is conveyed along the supply belt conveyor 11 of the continuous unloading machine 10 and falls into the discharge hopper 12. [ The conveyed matter 15 falling onto the discharge hopper 12 is dropped onto the belt member 21 of the belt conveyor 20 and conveyed along the belt member 21. [

4 and 5, when the belt member 21 is moved upward by the abnormal operation, the roller member 46 rotating in contact with the belt member 21 is also moved upward. The supporting member 44 for supporting the roller member 46 and the moving body 42 connected to the supporting member 44 are also moved upward.

The extension member 60 provided in contact with the belt member 21 is also moved upward so that the extension member 60 and the belt member 21 are moved upward, The transported object 15 is moved to block the generation of the falling light.

The extension member 60 is always moved up and down like the belt member 21 to keep the belt member 21 in contact with the belt member 21 so that the conveyed object 15 falls down between the extension member 60 and the belt member 21, Can be prevented. On the other hand, when the maintenance work is required, the operator can rotate the mounting frame 50 and the extension member 60 around the rotary connection portion 70, so that the maintenance work can be performed more easily.

As described above, according to the present invention, as the belt member 21 moves up and down, the extending member 60 facing the belt member 21 is also moved up and down to prevent falling of the conveyed object 15, Can be improved.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the invention as defined by the appended claims. will be.
