A driven gear 9 is fixedly sleeved on the output end of the driving motor 7, and the driving gear 10 and the driven gear 9 are meshed with each other.
[0024] The drying box 2 is provided with a rotating plate 11, a dust suction pipe 12, a spray pipe 16 and an air outlet pipe 13, one end of the air outlet pipe 13 is fixedly connected to the fixed pipe 20, and the air outlet pipe 13 is arranged parallel to the extension direction of the drying box 2, and the air outlet pipe 13 is connected to the air pump 4, and the air pump 4 is fixedly arranged on the base 8. The output end of the air pump 4 is connected to a ventilation pipe, which passes through the fixed pipe 20 and extends into the drying box 2 and is connected to the air outlet pipe 13, and the air outlet pipe 13 is provided with air outlets at equal distances along its extension direction.
[0025] A fixed plate is fixedly arranged below the fixed tube 20, one end of the rotating plate 11 passes through the fixed plate and is rotatably connected thereto, a first motor 19 is fixedly arranged on the mounting plate, and the first motor 19 drives the rotating plate 11 to axially rotate.

[0026] The drying box 2 is provided with flaps 14 evenly arranged on the inner wall of the drying box 2, and the flaps 14 are arranged perpendicular to the central axis of the drying box 2. The flaps 14 are made of heat-conducting metal material.
[0027] The dust suction pipe 12 is fixedly arranged above the flip plate 14, and one end of the dust suction pipe 12 is fixedly connected to the fixed pipe 20.

The water inlet end of the water pump can be connected to an external water inlet pipe. Spray heads are arranged on the spray pipe 16 at equal distances along its extension direction.
[0029] When the present invention is in use, the electric heating tube 15 is started to heat the side wall of the drying box 2. The side wall of the drying box 2 can conduct heat to the flip plate 14 and heat the inside of the drying box 2. Then the raw materials to be dried are poured into the feed pipe 1 and then enter the drying box 2. Then start the driving motor 7, the first motor 19 and the air pump 4. The driving motor 7 drives the heating box 18 to rotate axially through the driving gear 10 and the driven gear 9. The heating box 18 drives the drying box 2 to rotate axially. When the drying box 2 rotates, the flip plate 14 arranged on the inner wall can continuously pass through the raw materials piled at the bottom of the drying box 2 to flip the raw materials. The temperature in the drying box 2 can accelerate the drying rate of the raw materials. The flip plate 14 can contact the raw materials more evenly. When the raw materials are in contact with the flip plate 14, the heat on the flip plate 14 can also dry the raw materials. When the drying box 2 rotates axially, the flip plate 14 will drive part of the raw materials to move along the inner wall of the drying box 2 until the flip plate 14 moves to a certain angle, and the raw materials carried by it fall back to the bottom of the drying box 2 again. In this process, the raw materials can be turned over very well.
[0030] At the same time, the first motor 19 drives the rotating plate 11 to rotate axially. The rotating plate 11 drives the rubber column 6 arranged thereon to continuously stir the raw materials at the bottom of the drying box 2 during the rotation process, thereby playing the role of assisting in turning the raw materials. During this process, the air pump 4 is kept in the starting state. When the air pump 4 is started, the dust in the drying box 2 can be sucked into the filter device 5 through the dust suction pipe 12. The dust and impurities carried therein are filtered by the filter device 5 and then enter the air outlet pipe 13 again, and are blown toward the raw materials from the air outlet pipe 13 arranged on the air outlet pipe 13 to dry them.
[0031] When the drying box 2 needs to be cleaned, the water pump and the driving unit can be started, and the drying box 2 can be driven to rotate axially by the driving unit. The water inlet end of the water pump is connected to the water inlet pipe, and then the water is pumped into the spray pipe 16, and sprayed on the inner wall of the drying box 2 from the nozzle on the spray pipe 16 to clean the inner wall of the drying box 2. Since the drying box 2 rotates axially, the inner wall of the drying box 2 can be fully cleaned.
[0032] The present invention provides a drying box 2, and a heating box 18 is provided outside the drying box 2. The heating tube provided in the heating chamber can heat the drying box 2, and the driving unit is provided to drive the drying box 2 to rotate axially, so that the flip plate 14 provided on the inner wall of the drying box 2 can continuously contact the raw materials placed therein. When the flip plate 14 rotates continuously with the drying box 2, it can be well and evenly contacted with the raw materials and can flip the raw materials. The flip plate 14 can not only accelerate the drying effect on the raw materials, but also separate impurities such as dust adhering to the raw materials from the raw materials. In addition, by providing a dust suction pipe 12 and an air outlet pipe 13, the air pump 4 absorbs dust floating in the drying box 2 or adhering to the raw materials through the dust suction pipe 12. The dust-carrying air sucked in enters the blowing pipe after passing through the filtering device 5 to remove the dust, and is sprayed toward the raw materials from the air outlet on the blowing pipe to dry them. The air in the drying box 2 has a certain amount of heat under the heating of the electric heating tube 15, and is pumped into the drying box 2 through the air pump 4 to generate airflow, thereby accelerating the drying of the raw materials. The present invention has a simple structure, is practical and convenient, greatly improves the drying quality and rate of the raw materials, and has good practicality and applicability.
