Cooling mechanism for powder elevator

The utility model discloses a cooling mechanism for a powder elevator, which comprises an elevator, the top of the elevator is fixedly connected with a shell, one side of the shell is fixedly connected with a support plate, and the upper end of the support plate is fixedly connected with a shell. The cooling mechanism for the powder elevator is provided with the water receiving rod and the heat dissipation fan, the machine body in the shell is subjected to heat dissipation through the heat dissipation fan, a heat dissipation source and a power source of the heat dissipation fan both come from water in the water tank, the water in the water tank can be pumped into the connecting pipe through the water pump, and therefore heat dissipation is achieved. Then the water is discharged into the water receiving box for repeated use, meanwhile, the discharged water can be changed into a power source for rotation of the heat dissipation fan, the falling water can drive the power wheel to rotate, so that the heat dissipa
