The specific embodiment

Can more be expressly understood content of the present utility model and other advantage and effect with the following description in conjunction with the drawings.

Embodiment 1: as shown in Figure 1, in cold season, surface temperature is lower than subsurface temperature, in order to make full use of underground heat, ball mill of the present utility model also comprises one group of such equipment, be about to water pipe 2 and be embedded in undergroundly, soil 1 absorbs underground heat as heat-insulation layer simultaneously, after water pipe 2 elevates above the soil, be covered with water pipe heat-insulating layer 3 in these water pipe 2 outsourcings, through the control of penstock 5, the hot water in the underground heat is flow in the ball mill via hot-water line 25, thereby realization provides the purpose of hot water in ball mill.
