  • Cement heating and finishing machine
    Patent number: 7674068
    Abstract: The cement finishing machine (10) has adjustable heat generating assemblies (22, 24), affixed to each side of the finishing machine (10). Each of the heat generating assemblies (22, 24) includes a propane burner that extends into an elongate heating tube. The heat generating assemblies (22, 24) also include a vertical adjustment assembly and detachable heat guards. The heat generated by the propane burner is directed through an opening in the bottom of each of the heating tubes and onto the surface of an unfinished cement slab during the cement finishing process. The heat facilitates the evaporation of excess water generated during the cement finishing process.
