[0012] As a further description of the above technical solution:

[0013] The mounting frame has a rotating groove on its inner side, and multiple fan blades are rotatably mounted on the inner side of the rotating groove.

[0014] As a further description of the above technical solution:

[0015] One end of the fan blade is provided with a threaded sleeve, and the traveling wheel is tactilely connected to the conical cover.

[0016] As a further description of the above technical solution:

[0017] The tea leaf turning assembly is equipped with a turbulence-inducing component, which includes a toothed disc. A rotating shaft is provided on the bottom surface of the toothed disc. The rotating shaft is rotatably mounted on the top surface of the turning blades. Turbulence-inducing blades are fixedly installed on the outside of the rotating shaft.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0023] 1. In this utility model, a tea-turning component and a tea-holding component are provided inside. Through this design, a conical material-bearing structure is adopted. After the tea leaves are added, they will accumulate on the surface of the material-bearing structure. With the application of the turning structure, real-time and comprehensive turning of the tea leaves can be achieved during the drying process, which greatly improves the drying uniformity and drying effect of the tea leaves. At the same time, the material-discharging plate close to the surface of the material-bearing structure can also work simultaneously, which can effectively dissipate some tea leaves that are damp and adhered to the surface of the material-bearing structure, further improving the drying effect and comprehensiveness of the tea leaves. It can also complete automatic discharge, which is convenient and fast.

[0024] 2. In this utility model, a turbulence-inducing component is provided. When the turning blades rotate, the turbulence-inducing component on them can rotate. At this time, the toothed disc can mesh with the meshing teeth on the inner wall of the equipment and rotate, synchronously driving the turbulence-inducing blades to rotate. The turbulence-inducing blades can make the hot airflow inside the equipment flow quickly, thus drying the tea leaves. At the same time, when the reciprocating screw is driven to rotate, it can drive the moving disc on it to move up and down, so that the longitudinal stud can move up and down synchronously. When the longitudinal stud meshes with the screw sleeve, it can drive the fan blades to rotate. The fan blades generate airflow at the bottom. The airflow can finally flow to the working area through the air groove at the top of the conical cover, working together with the turbulence-inducing component to further improve the drying effect of the tea leaves.

[0036] The tea leaf turning component 4 and the tea leaf holding component 5 are provided. The tea leaf holding component 5 is located inside the drying cylinder 3, and the tea leaf turning component 4 is located at the output end of the drive motor 7.

[0037] The tea leaf turning assembly 4 includes a reciprocating screw 45, which is fixedly installed on the output end of the drive motor 7. Turning blades 43 are fixedly installed on the outside of the reciprocating screw 45. An installation groove 41 is provided on the inner side of the turning blades 43. An installation shaft is rotatably installed on the inner wall of the installation groove 41. A material-pulling plate 44 is fixedly installed on the outside of the installation shaft.

[0038] The tea-holding assembly 5 includes a conical cover 51, which is fixedly installed inside the drying cylinder 3. An installation cylinder 52 is fixedly installed at the center of the conical cover 51. An electric heating tube is provided inside the shell cavity of the conical cover 51. Several air grooves are provided at the top of the conical cover 51. One end of the reciprocating screw 45 is rotatably installed inside the installation cylinder 52.

[0039] When drying tea leaves, turn on the heating element, remove the top cover 1, and add the tea leaves into the drying cylinder 3. The tea leaves will scatter on the outside of the conical cover 51. At this time, turn on the drive motor 7 to drive the tea leaf turning component 4 to rotate. The turning blades 43 can turn the tea leaves in real time. At the same time, the traveling wheels 42 can roll on the outer surface of the conical cover 51, and the feeding plate 44 can rotate synchronously to further turn the tea leaves that are wet and adhered to the surface of the conical cover 51. After drying, open the discharge port 2 to remove the tea leaves.

[0040] like Figures 3-5 As shown, the tea leaf turning assembly 4 is equipped with a turbulence component 9, which includes a toothed disc 91. A rotating shaft is provided on the bottom surface of the toothed disc 91. The rotating shaft is rotatably mounted on the top surface of the turning blades 43.

When the toothed disc 91 rotates, it can mesh with the meshing teeth 8 on the inner wall of the equipment and rotate, which synchronously drives the turbulence vane 92 to rotate. The turbulence vane 92 can make the hot airflow inside the equipment flow quickly to dry the tea leaves. At the same time, when the reciprocating screw 45 is driven to rotate, it can drive the moving disc 6 on it to move up and down, so that the longitudinal stud 10 moves up and down synchronously. When the longitudinal stud 10 meshes with the screw sleeve 55, it can drive the fan blade 54 to rotate. The fan blade 54 generates bottom airflow. The airflow can finally flow to the working area through the air groove at the top of the conical cover 51 to dry the tea leaves.
