[0011] Preferably, a fan body is installed on the top of the heating device body through a connecting pipe, one side of the fan body is installed in communication with the lower side of the shell through an air inlet pipe, and one side of the heating device body is installed in communication with the upper side of the shell through an air outlet pipe.

[0012] Preferably, a filter screen is fixedly installed on one side of the air inlet pipe and the air outlet pipe close to the shell.

[0013] Preferably, the lower part of one side of the auger conveyor is connected to the lower part of the other side of the shell through a second discharge pipe, the upper part of one side of the auger conveyor is connected to the upper part of the other side of the shell through a return pipe, and the upper part of the other side of the auger conveyor is connected to the first discharge pipe.

[0014] Preferably, the return pipe and the first discharge pipe are respectively provided with flap valves.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] The utility model arranges an auger conveyor so as to turn over the raw materials in the shell. Meanwhile, the arrangement of the heating device body and the fan body can input hot air into the shell. Thus, when the raw materials are in use, the raw materials stored in the shell can be heated and dried, thereby achieving the effect of drying the raw materials when they are ground.
