Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

[0025] Please refer to Figure 1 With Figure 2 , the present invention provides a technical solution for a tea dryer that can be graded: a tea dryer that can be graded, including a drying box 1. One side of the top of the drying box 1 is provided with a feed hopper 2, and one side of the top of the drying box 1 is fixedly communicated with an exhaust pipe 3. Through the exhaust pipe 3, the water vapor generated during the tea drying process can be discharged outward, which can improve the drying efficiency of the tea. The upper and lower parts of the inner wall of the drying box 1 are provided with inclined support frames 10. Inside the support frames 10, there is a drying component 5 that can dry the tea. In the middle of the top of the support frames 10, there is a turning component 6 that can turn the tea. At the bottom of one inner wall of the drying box 1, there is a guiding frame 7. At the bottom of the guiding frame 7, there is a guiding pipe 11. At the bottom of the guiding pipe 11, there is a drum sieve 12. The inner bottom wall of the drying box 1 is slidably connected with a collection frame 13. The collection frame 13 is located below the drum sieve 12. Through the collection frame 13, the broken tea sieved by the drum sieve 12 can be collected. On one side of the bottom of the inner cavity of the drying box 1, there are symmetrically arranged fixing plates 8 up and down. Between the two fixing plates 8, there is a driving component 9 that can control the rotation of the drum sieve 12 to remove the broken leaves in the tea. One side of the bottom of the drying box 1 is fixedly connected with a discharge pipe 4. One side of the drum sieve 12 is rotatably connected inside the discharge pipe 4.

[0026] Please refer to Figure 3 , the drying component 5 includes support rollers 51 rotatably connected to both sides of the inner wall of the support frame 10. A conveying plate chain 52 is sleeved on the outer sides of the two support rollers 51. One side of the drying box 1 is fixedly connected with a first motor 53. One side of the output shaft of the first motor 53 is fixedly connected with the support roller 51. In the middle of the inner wall of the support frame 10, there is a fixed frame 54. The fixed frame 54 is located in the middle of the conveying plate chain 52. The inner wall of the fixed frame 54 is fixedly connected with a heating wire 55. By controlling the first motor 53 to start, the support roller 51 is driven to rotate, thereby driving the conveying plate chain 52 to slowly convey the tea on it. By energizing the heating wire 55 inside the fixed frame 54, the heating wire 55 emits heat to dry the tea. The tea is conveyed downward by the action of the conveying plate chain 52 into the next support frame 10, and multi-stage drying of the tea can be carried out.

[0027] Please refer to Figure 4The turning assembly 6 includes a connecting frame 61 fixedly connected to the middle part of the top of the supporting frame 10, and the inner top wall of the connecting frame 61 is fixedly connected with fixed rods 62 arranged at equal distances, and the bottom ends of the fixed rods 62 are fixedly connected with turning plates 63. When the tea leaves pass through the inside of the connecting frame 61, the turning plates 63 can turn the tea leaves on the conveyor plate chain 52 to both sides, so that the tea leaves are heated more evenly, and the number of times the tea leaves are turned is less, which can reduce the breakage rate of the tea leaves.

[0028] See also Figure 5 The driving assembly 9 includes a driving frame 91 fixedly connected between the two fixed plates 8, one side of the drum screen 12 is rotatably connected to the inside of the driving frame 91, and the top of the inner wall of the driving frame 91 is rotatably connected to a worm 93, one side of the driving frame 91 is fixedly connected to a second motor 92, one end of the output shaft of the second motor 92 is fixedly connected to the worm 93, and the outer side of one end of the drum screen 12 is fixedly sleeved with a worm gear 94, which is meshingly connected to the worm 93. By controlling the second motor 92 to drive the worm 93 to rotate, the worm 93 is meshed with the worm gear 94 installed on the outer side of the drum screen 12, which can drive the drum screen 12 to rotate stably, turn the tea leaves therein, and make the broken leaves in the tea fall downward through the sieve holes of the drum screen 12, so that the broken leaves can fall into the inside of the collecting frame 13, thereby completing the screening of the tea leaves.

[0029] The working principle and use process of the utility model are as follows: tea leaves are poured into the drying box 1 through the feed hopper 2, so that the tea leaves fall on the conveyor plate chain 52, and then the first motor 53 is controlled to start, driving the supporting roller 51 to rotate, thereby driving the conveyor plate chain 52 to slowly convey the tea leaves thereon, and when the tea leaves pass through the interior of the connecting frame 61, the tea leaves can be turned to both sides by the turning plate 63, so that the tea leaves at the bottom are turned to the top, and the electric heating wire 55 inside the fixing frame 54 is energized to make the electric heating wire 55 emit heat to dry the tea leaves, and the tea leaves are transported downward to the next supporting frame 54 under the action of the conveyor plate chain 52. Inside the support frame 10, the tea leaves can be subjected to multi-stage drying treatment. After the tea leaves are dried, they enter the inside of the drum screen 12 through the guide frame 7 and the guide pipe 11. The second motor 92 is controlled to drive the worm 93 to rotate, so that the worm 93 and the worm wheel 94 installed on the outside of the drum screen 12 are meshed and transmitted, which can drive the drum screen 12 to rotate stably, turn the tea leaves therein, and make the broken leaves in the tea fall downward through the sieve holes of the drum screen 12, so that the broken leaves can fall into the inside of the collecting frame 13, thereby completing the screening of the tea leaves, and then the tea leaves in the drum screen 12 slide downward and are discharged through the discharge pipe 4.
