The chain 43 is hung by the first teeth 41a and the second teeth 42a to move in an endless track. Therefore, when the first rotary body 41 is rotated, the chain 43 is moved, the second rotary body 42 is rotated by the movement of the chain 43. When the second rotating body 42 is rotated in conjunction with this cleaning bar 22 is rotated.

The belt conveyor 1 according to the embodiment of the present invention is provided with an injection unit 60. The injection unit 60 injects the washing water to the return belt 12 when the return belt 12 is moved. More specifically, the injection unit 60 is operated in conjunction with the second rotating body 42.

The injection unit 60 according to an embodiment of the present invention is provided with a spray pipe 61, a mounting table 62, a swivel table 63, a switch 64, an elastic body 65, and a protrusion 66.

The injection pipe 61 is located below the return belt 12, and a plurality of nozzles 61a for spraying the washing water are formed. The washing water sprayed through the nozzle 61a washes the conveyed material attached to the return belt 12.

The mounting table 62 is installed at one end of the injection pipe 61. More specifically, the mounting table 62 protrudes upward from the upper surface of the injection pipe 61.

The rotating table 63 is rotatably coupled to the mounting table 62. The rotary part 63 is the central portion is coupled to the mounting table 62 and the hinge (63a).

The switch 64 is provided in the injection pipe 61 and protrudes upward from the injection pipe 61. The switch 64 is moved downward as the rotary table 63 is rotated and pressed, and is moved upward by its elastic restoring force when the external force by the rotary table 63 disappears.

The switch 64 controls the valve which opens and closes each nozzle 61a. Therefore, when the switch 64 is moved downward, the valve opens the nozzle 61a to inject the washing water, and when the switch 64 is moved upward, the valve closes the nozzle 61a to stop the washing water injection. .

One end of the elastic body 65 is coupled to the injection pipe 61, and the other end thereof is coupled to the swivel 63 to elastically support the swivel 63.

The projection 66 is coupled to the second rotating body 42 and rotates in conjunction with the second rotating body 42. The protrusion 66 is caught by the rotary table 63 while being rotated. When the projection 66 is caught by the rotary table 63, the rotary table 63 is rotated while being pushed by the rotational force of the projection 66.

Referring to the operation of the belt conveyor 1 according to an embodiment of the present invention having a structure as described above are as follows.

When the driving roller 15 is driven, the conveying belt 11 and the conveying belt 12 moves in an endless track. At this time, the conveying belt 11 carries the conveyed material, and the conveying belt 12 is partially attached to the conveying object.

When the return belt 12 is moved, the return roller 32 in contact with the return belt 12 is rotated, and the first rotating body 41 coupled with the return roller 32 is interlocked with the return roller 32. Is rotated.

When the first rotating body 41 is rotated, the chain 43 winding the first teeth 41a formed on the outer circumferential surface of the first rotating body 41 moves in an endless track. At this time, the second rotary body 42 wound on the chain 43 is also rotated.

When the second rotating body 42 is rotated, the cleaning bar 22 coupled thereto is rotated, and the plurality of cleaning bodies 23 coupled to the outer circumferential surface of the cleaning bar 22 are scraped and attached to the return belt 12. The finished feed.

The transported material attached to the return belt 12 and dropped by the cleaning body 23 is guided to the storage by the guide unit 50.

On the other hand, the projection 66 coupled to the second rotating body 42 is rotated in conjunction with the second rotating body 42 to lift one end of the rotating table (63).

Then, the rotary table 63 is rotated about the hinge 63a, and the other end of the rotary table 63 is moved downward.

The other end of the rotating table 63 moved downward presses the switch 63, and the pressurized switch 63 moves downward to open the nozzle 61a. For this reason, the washing water is sprayed to the return belt 12 to wash the return belt 12.

When the projection 66 pushes up one end of the rotary table 63 and is spaced apart from the rotary table 63 by the rotational trajectory, the other end of the rotary table 63 moved downward by the restoring force of the elastic body 65 is raised.

Then, the swivel 63 releases the pressure on the switch 64, the switch 64 released the pressure is raised by its elastic restoring force.

When the switch 64 is raised, the valve restricts the movement of the washing water, so that the washing water is not sprayed through the nozzle 61a.

Therefore, as the second rotating body 42 is rotated, the protrusion 66 repeatedly pushes the rotating table 63, thereby repeating the process of washing the water return belt 12.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and those skilled in the art to which the art belongs can make various modifications and other equivalent embodiments therefrom. I will understand.
