[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 This utility model provides a technical solution: a tea withering trough with a uniform heating structure, including a trough body 1, a filter screen 2, a threaded rod 3, a scraper 4, a first conical tooth 5, a second conical tooth 6, a transmission rod 7, a handle 8, a support frame 9, a fixing rod 10, a reciprocating screw 11, a motor 12, a fan 13, a diversion pipe 14, a mounting groove 15, a wheel 16, a fixing block 17, a locking block 18, and a spring 19.

[0027] When using a tea withering trough with a uniform heating structure, for example, with... Figure 1 Appendix Figure 2 and attached Figure 3 As shown, a reciprocating screw 11 is connected to the rear end of the support frame 9, a fan 13 is installed at the upper end of the support frame 9, a diversion pipe 14 is connected to the lower end of the support frame 9, a fixed rod 10 is connected to the lower side of the front end of the support frame 9, and a reciprocating screw 11 is connected to the lower side of the rear end of the support frame 9. A motor 12 is installed at the lower right end of the reciprocating screw 11. When the fan 13 is started, hot air is output downward through the pipe. At this time, the hot air is evenly distributed through the diversion pipe 14. The diversion pipe 14 heats the tea stored in the upper filter screen 2 and the lower mounting slot 15 inside the tank 1. Then, the motor 12 is started to drive the reciprocating screw 11 to rotate, so that the reciprocating screw 11 drives the support frame 9 to move back and forth along the path of the fixed rod 10, which drives the diversion pipe 14 to evenly heat the tea inside the tank 1. This is the usage method of the tea withering tank with a uniform heating structure.

[0028] When turning the tea leaves inside the withering trough, for example, attaching... Figure 1 Appendix Figure 3 Appendix Figure 4 and attached Figure 5As shown, a first bevel tooth 5 is installed at the front end of the threaded rod 3. The left side of the first bevel tooth 5 is connected to the second bevel tooth 6 by meshing. A transmission rod 7 is connected inside the second bevel tooth 6. A handle 8 is installed at the left end of the transmission rod 7. A locking block 18 is connected to the upper end of the fixing block 17. A spring 19 is installed at the upper end of the locking block 18. When a large amount of tea leaves need to be stored in the tank 1 for withering, tea leaves are first placed on the upper end of the filter screen 2, and then some tea leaves are stored in the installation groove 15. The wheels 16 and the fixing block 17 on the left and right sides of the installation groove 15 are inserted into the sliding groove on the inner wall of the filter screen 2. At this time, the installation groove 15 is pushed into the tank 1. The installation groove 15 drives the fixing block 17 to engage with the locking block 19. When block 18 is squeezed, it causes the locking block 18 to press upward against the spring 19. After the fixing block 17 moves the groove to the lower end of the locking block 18, the spring 19 uses its elasticity to lock the locking block 18 into the groove of the fixing block 17, thus fixing the mounting slot 15 in place. After the tea leaves inside the diversion pipe 14 have been heat-treated for a long time, they need to be turned over. At this time, the handle 8 is held and the transmission rod 7 drives the second bevel tooth 6 to rotate. The second bevel tooth 6 meshes with the first bevel tooth 5. The second bevel tooth 6 then drives the threaded rod 3 through the first bevel tooth 5 to move the scraper 4 back and forth along its path. The lower end of the scraper 4 then performs a uniform turning process on the tea leaves, thereby achieving the turning of the tea leaves in the withering trough.
