[0014] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.
[0015] Please refer to Figures 1-4 , a pre-pressing roller device of a paving machine in the utility model includes a pre-pressing roller 1 and a cleaning brush roller 8. Side plates 2 are arranged at both ends of the pre-pressing roller 1. The pre-pressing roller 1 rotates on the side plates 2. The side plates 2 are used to fix the pre-pressing roller 1. The roller shaft of the pre-pressing roller 1 rotates on the side plates 2 through bearings. The cleaning brush roller 8 is arranged on the side of the pre-pressing roller 1. The axes of the cleaning brush roller 8 and the pre-pressing roller 1 are parallel. The roller surface of the cleaning brush roller 8 is in contact with the roller surface of the pre-pressing roller 1. Installation brackets are arranged at both ends of the cleaning brush roller 8. The installation brackets are fixed on the side plates 2. A driving mechanism for driving the cleaning brush roller 8 to rotate on the installation brackets is arranged on the installation brackets, that is, the roller shaft of the cleaning brush roller 8 rotates on the installation brackets through bearings. The rotation speeds of the cleaning brush roller 8 and the pre-pressing roller 1 are different, and the rotation directions are the same.
