The driving sprocket 5 and the driven sprocket 42 are connected through a chain transmission.

[0023] The following is a detailed description of the specific settings and functions of this embodiment. When paving materials, the operator shovels the materials into the hopper 21, uses the driving rear wheel 13 to drive the active sprocket 5, and uses the chain to drive the driven sprocket 42 to input power to the gear box 41.
