DETAILED DESCRIPTION

[0026] Embodiment 1

[0027] like Figure 1-Figure 4 As shown, the material turning mechanism proposed in the utility model includes a barrel body, a rotating shaft 5, a rotating roller 8, a gear ring 12 and a driving assembly. A discharge port 201 connected to the inside of the barrel body is provided at the bottom of the barrel body, and a door plate 202 for closing the discharge port 201 is rotatably connected to the barrel body. The barrel body is connected to the feed hopper 4, and a bucket cover for closing its opening is provided on the feed hopper 4. The barrel body includes a storage barrel 2 and an end cover 3, wherein the storage barrel 2 is a columnar tube, and the two end covers 3 are connected to the storage barrel 2 and respectively close the openings on both sides thereof. The rotating shaft 5 is inserted into the barrel body and rotatably connected to the barrel body, the rotating shaft 5 is connected to the bracket 51, the bracket 51 is connected to the scraper 7, and the scraper 7 is slidably connected to the inner wall of the inner cavity of the barrel body. The two ends of the rotating shaft 5 respectively pass through the corresponding side end covers 3 and are rotatably connected thereto. The roller 8 is parallel to the scraper 7, and the roller 8 is rotatably connected to the bracket 51. A spiral plate 9 is arranged on the arc surface of the roller 8 around its axis, and gears A10 are arranged at the ends of the roller 8, and two adjacent gears A10 are meshed and connected. The gear ring 12 is connected to the barrel body, and a gear B11 meshed and connected therewith is arranged on the inner side of the gear ring 12, and the gear B11 is connected to one of the rollers 8. A circular groove 301 is arranged on one side of the end cover 3, and the opening of the circular groove 301 faces the other side end cover 3. The gear ring 12 is located in the circular groove 301 and connected to its inner wall, and the gear B11 is located on the inner side of the gear ring 12 and meshed and connected therewith. The rotating shaft 5 is rotatably connected to the rotating disk 302, and the rotating disk 302 is inserted into the circular groove 301 and slidably connected to its inner wall. The driving component drives the connected rotating shaft 5 to drive the scraper 7 to rotate with the rotating shaft 5. The driving assembly includes but is not limited to the motor 6 and the transmission assembly. The transmission assembly includes a sprocket and a chain. The two sprockets are respectively connected to the output end of the motor 6 and the end of the rotating shaft 5. The chain transmission connects the two sprockets.

[0028] In this embodiment, the motor 6 is started and drives the rotating shaft 5 to rotate through the sprocket and chain structure. The rotation of the rotating shaft 5 drives the bracket 51, the scraper 7 and the roller 8 to rotate around the axis of the rotating shaft 5. The scraper 7 brings up the wet material at the bottom of the inner cavity of the storage barrel 2. When the wet material reaches a certain height, it is thrown downward along the inclined surface of the scraper 7. The agglomerated wet material falls between the rollers 8. Since the rollers 8 are meshed with the gear ring 12 through the gear B11, and the two adjacent rollers 8 are meshed through the two gears A10, the rollers 8 rotate themselves in the process of following the rotation of the rotating shaft 5 under the meshing of the gear B11 and the gear ring 12. At the same time, the rotation directions of the two adjacent rollers 8 are opposite, resulting in the opposite screwing directions of the spiral plate 9. The relatively rotating spiral plate 9 rubs the lumps in the raw material, thereby achieving the purpose of deblocking. In this embodiment, the turntable 302 can effectively prevent the raw material from entering the gap between the gear B11 and the gear ring 12.

[0031] In this embodiment, during the operation of the fan 16, hot air is extracted from the heating box 13, and then the gas in the storage barrel 2 is driven to flow into the heating box 13 along the connecting pipe 14 on one side. The fan 16 then delivers the hot air into the storage barrel 2 to form a circulation. This structure can effectively avoid the waste of hot air and reduce energy consumption while ensuring drying efficiency.
