[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This device uses a stacking structure to stack multiple drying trays. The special-shaped block at the top of the first rotating shaft cooperates with the special-shaped groove of the fixing sleeve inside the drying tray. The drying trays can be plugged into the special-shaped block at the top of the first rotating shaft layer by layer to form a stacked material rack. The cooperation between the special-shaped block and the special-shaped groove facilitates the installation and removal of the drying trays and the loading and unloading of materials. At the same time, when the first rotating shaft rotates, the drying trays can rotate with it, ensuring that the materials are fully exposed to the hot air during the drying process, thereby improving drying efficiency. 2. This device rotates several drying plates through a rotating structure. A motor drives the connected pinions, which mesh with the large gears to achieve synchronous rotation of the three large gears and the first rotating shaft. The first rotating shaft then drives the special-shaped blocks, which, through the cooperation of the special-shaped blocks and the special-shaped slots, drive the drying plates to rotate. This causes the material within the drying plates to continuously rotate horizontally, further improving the uniformity of material heating and preventing local overheating or uneven drying. Compared to traditional static drying, this dynamic rotation method effectively avoids overheating and burning of the material caused by prolonged local heating. 3. The device drives the deflection angle of the flow guide swing piece through the setting of the angle adjusting structure. When the first rotating shaft rotates, the circular rod at the bottom end drives the linkage frame to move. The first through groove and the second through groove inside the linkage frame cooperate with the first protruding column and the second protruding column respectively, so that the movable plate moves periodically inside the fixed base, and then drives the connecting plate and the sliding plate to move reciprocally, thereby realizing the adjustment of the angle of the flow guide swing piece. The change of the angle of the flow guide swing piece can adjust the flow direction of the hot air in the drying compartment, so that the hot air is more evenly distributed in the drying compartment. The uniform distribution of the hot air can reduce the phenomenon of insufficient drying or excessive drying of the material caused by local temperature unevenness, and improve the drying uniformity of the material. 4. The device realizes the stirring operation of the material in the drying disc through the setting of the stirring structure. In the process of rotating the pinion gear driven by the motor, the three gear wheels cooperate with the pinion gear to drive the three pinion gears, the second rotating shaft and the reciprocating screw rod to rotate synchronously, and then drive the threaded sleeve and the second driving rack to move up and down reciprocally. The second driving rack is engaged with the second driven gear, thereby driving the rotating cylinders, the connecting rods and the back-shaped frame to move reciprocally. The back-shaped frame moves reciprocally above the drying disc to stir the material in the drying disc, so that the material is constantly turned over during the drying process, breaking the stationary state of the material during the drying process, further improving the contact area of the material and the hot air, and accelerating the drying speed, while preventing the material from caking or sticking during the drying process.

Embodiment 3

[0038] With reference to Figures 1-10 The embodiment is based on the previous embodiment, and differs from the previous embodiment in that the rotating structure comprises a first rotating shaft 16, a large gear 17, a round rod 18, a linkage frame 19, a first through groove 20, a first protruding column 21, a second through groove 22, a movable plate 23, and a second protruding column 24. The first rotating shaft 16 penetrates through the fixed base 9 and is fixedly connected with the large gear 17 at the bottom. The three large gears 17 are not in contact with each other. The first rotating shaft 16 is fixedly connected with the round rod 18 at the bottom end. The linkage frame 19 is rotatably connected with the round rod 18.

One end of the threaded sleeve 36 is fixedly connected with the second driving rack 37.

[0042] A plurality of rotating cylinders 38 are rotatably connected inside the fixed box 33. The rotating cylinder 38 is fixedly connected with the second driven gear 39. The second driven gears 39 are in meshing connection with the second driving rack 37. One end of the rotating cylinder 38 close to the drying disc 30 penetrates through the fixed box 33 and is threadedly connected with the threaded block 41. The inside of the threaded block 41 is provided with the slot 43. The rotating cylinder 38 is inserted with the plug rod 44. The plug rod 44 is matched with the slot 43.

The bottom end of the connecting rod 40 is fixedly connected with the back-shaped frame 42.

[0043] In use, the motor 28 drives the small gear 27, and the three large gears 17 and the three small gears 27 are matched to drive the three small gears 27 to rotate synchronously, and then drive the three second rotating shafts 26 to rotate synchronously. When the second rotating shaft 26 rotates, it drives the reciprocating screw rod 34 to rotate, and the threaded sleeve 36 moves linearly on the reciprocating screw rod 34, and is guided by the guide rod 35 to ensure stability. The second driving rack 37 at one end of the threaded sleeve 36 is engaged with the second driven gear 39 on the rotating cylinder 38 during reciprocating movement, driving the rotating cylinder 38 to rotate synchronously. When the rotating cylinder 38 rotates, the connecting rod 40 and the back-shaped frame 42 are driven to move through the threaded block 41. The back-shaped frame 42 moves reciprocally above the drying disc 30 to stir the materials in the drying disc 30, so that the materials are continuously turned over during drying, breaking the static state of the materials during drying, further increasing the contact area of the materials and hot air, accelerating the drying speed, and preventing the materials from caking or sticking during drying. The device connects the rotating cylinder 38 and the threaded block 41 in a plug rod 44 and a plug groove 43 matching mode. Before drying starts, after the plurality of drying discs 30 are sequentially installed on the special-shaped block 29, the threaded block 41 is sequentially installed on the rotating cylinder 38, and then the plug rod 44 is inserted into the rotating cylinder 38 and the threaded block 41 to complete the installation of the back-shaped frame 42. When drying is completed, the plug rod 44 is pulled out of the plug groove 43, and the back-shaped frame 42 can be quickly disassembled. The device only needs one motor 28 as a power source, and through gear transmission and connecting rod mechanism, the functions of rotating the drying disc 30, adjusting the angle of the flow guide swing piece 11, and stirring the back-shaped frame 42 are realized. The rotating drying disc 30 rotates the materials in the horizontal direction, the flow guide swing piece 11 adjusts the hot air flow direction, and the back-shaped frame 42 stirs the materials to turn over up and down. The three work together to ensure that the hot air can uniformly and fully contact the materials from multiple dimensions, further improving the drying effect and making the drying process more efficient, uniform and stable.
