1. A fodder-feeding disc wire driving device having the tension management unit, the driving device comprising:
a drive motor; a drive sprocket having multiple protrusions on a circumference thereof, the drive sprocket being rotatable by being connected to a drive motor, wherein discs provided on a disc wire engage with the multiple protrusions so that the disc wire conveys fodder; an idle wheel provided at a position adjacent to the drive sprocket such that the disc wire moved by the drive sprocket passes over the idle wheel, wherein the idle wheel is rotated by a rotational force of the drive sprocket transmitted to the idle wheel by the disc wire; a tension adjustment unit connected to a central shaft of the idle wheel, the tension adjustment unit being movably provided on a line extending between a central axis of the drive sprocket and a central axis of the idle wheel, wherein the tension adjustment unit constantly maintains tension of the disc wire by moving the idle wheel away from the drive sprocket by using an elastic force of a spring; a casing having a disc wire inlet and a disc wire outlet so that after the disc wire is introduced into the casing, and passes over both the drive sprocket and the idle wheel, the disc wire is discharged from the casing, with the drive motor, the drive sprocket, the idle wheel, and the tension adjustment unit being put in the casing; and a tension measurement unit mechanically provided between the casing and the tension adjustment unit, the tension measurement unit enabling tension state of the disc wire to be checked by naked eye, and enabling determination of when maintenance of the disc wire and adjustment of the idle wheel are required, wherein the tension measurement unit includes: a gauge hole having a scale and provided at a predetermined position of the casing, the gauge hole being configured in a longitudinal hole shape in the same direction as a moving direction of the idle wheel; and an indication protrusion provided by extending from a moving plate of the tension adjustment unit, the indication protrusion protruding through the gauge hole from the moving plate. |
