The present invention relates to a circular baler having lower driving noises. More specifically, a noise reducing member made of elastic material is equipped on the outer circumferential surfaces of bearing means installed at particular intervals along the length direction of bale forming chains in order to come in contact with a guide rail, so that contact noises generated when the circular baler is operated are reduced and the breakdown of bearings caused by shock from contact with the guide rail can be prevented. The circular baler of the present invention comprises the following parts: a baling room having an accommodating space for fodder crops therein; and a coupling unit which entangles and compresses fodder crops collected in the baling room in order to be circularly coupled. The coupling unit comprises the following: a pair of bale forming chains which are respectively installed at the left and right edges of the baling room and have a partial section which moves along a circular trajectory with a particular radius based on a central line, which is horizontal in respect to the left and right extended direction of the baling room; multiple coupling rollers which have both ends supported by the bale forming chains and are installed to be separated from each other in the length direction of the bale forming chains; multiple bearing means which are installed at particular intervals along the length direction of the bale forming chains; and a guide rail which is respectively installed at the left and right edges of the baling room and comes in contact with the bearing means so that the bale forming chains are guided and moved in a partial section. The bearing means comprise noise reducing members made of elastic material that come into contact with the guide rail. |
