[0024] 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.
[0025] Reference Figure 1 , Figure 3 , Figure 4This utility model provides an embodiment of a drum-type black tea dryer, comprising a protective shell 1, a base 2 fixedly connected inside the protective shell 1, support frames 13 fixedly connected to both sides of the top of the base 2, a drive shaft 9 rotatably connected inside the support frames 13, rollers 11 fixedly connected to both sides of the outside of the drive shaft 9, a gear 12 fixedly connected to the center of the outside of the drive shaft 9, a fixing block 23 fixedly connected to the top of the base 2, a motor 26 fixedly connected to the top of the fixing block 23, the output end of the motor 26 fixedly connected to one end of one of the drive shafts 9 near the fixing block 23, and a rolling ring 18 provided between two adjacent rollers 11. One of the roller rings 18 has a roller 3 16 fixedly connected inside, and another roller 14 has a roller 1 fixedly connected inside. The roller 2 15 is slidably connected to the left side of the roller 3 16. The roller 2 15 is fixedly connected to the outside of the roller 2 15. The roller 17 meshes with the top of the gear 12. The cylindrical screen 20 is fixedly connected to the right side of the roller 3 16. The rotating plate 28 is slidably connected inside the cylindrical screen 20. The side of the rotating plate 28 away from the cylindrical screen 20 is fixedly connected to the transmission rod 22. The top of the base 2 is fixedly connected to the support column 21. The top of the support column 21 is fixedly connected to the motor 27. The transmission rod 22 is fixedly connected to the output end of the motor 27. By starting the motor 27, the transmission rod 22 is driven to rotate. At this time, the transmission rod 22 drives the turning plate 28 to turn the material. The dried material in the drum 16 is dispersed by the turning plate 28, which avoids clumping. At the same time, with the cooperation of the turning plate 28, the cylindrical screen 20 removes the impurities in the material through the screen holes and falls into the second collection box 25. Larger and better quality materials cannot pass through the screen holes and eventually fall into the first collection box 24.
[0026] Reference Figures 1-5 Two fixed shells 19 are fixedly connected to both sides of the outer side of the roller 15. A limit plate 29 is fixedly connected to the bottom of the fixed shell 19.

A spring 33 is fixedly connected to the side of the sliding block 30 away from the limit plate 29. A fixed plate 31 is fixedly connected to the outside of the fixed shell 19. A sliding plate 32 is slidably connected through the left side of the fixed shell 19. Pulling the pulling plate 35 causes the pin 34 to move away from the limit plate 29. When one side of 9 moves, the sliding block 30 is fixedly connected to the pin 34. The sliding block 30 moves with the pin 34. After the sliding block 30 moves a certain distance, the sliding plate 32 that abuts against the sliding block 30 no longer contacts. Under the action of gravity, the sliding plate 32 locks the sliding block 30. At this time, the roller 14, roller 36 and roller 25 can be disassembled and separated. When installation is required, simply pull the sliding plate 32. At this time, the spring 33 returns the pin 34 to fix the roller 14, roller 36 and roller 25 again.
[0027] Reference Figure 1 , Figure 2 , Figure 5A rotating shaft 7 is fixedly connected to the top right side of the protective shell 1. The protective shell 1 is made of alloy material, providing high support strength. An arc-shaped drying chamber cover 8 is rotatably connected to the top of the rotating shaft 7. The arc-shaped drying chamber cover 8 can be rotated and moved away by the rotating shaft 7. The arc-shaped drying chamber cover 8 is equipped with heating wires inside. A conical cylinder 6 is fixedly connected to the left side of the roller 14. A feeding cylinder 4 is rotatably connected to the left side of the conical cylinder 6. The conical cylinder 6 and the feeding cylinder 4 are made of aluminum alloy material, which reduces weight while providing good material strength. A fan 3 is fixedly connected to the left side of the feeding cylinder 4. A feeding port 5 is fixedly connected through the top of the feeding cylinder 4. A bracket 10 is fixedly connected to the outside of the feeding cylinder 4. 10 is fixedly connected to the outer wall of the protective shell 1. A collection box 1 24 is fixedly connected to the top of the base 2. A support rod 36 is fixedly connected to the top of the base 2. A collection box 25 is fixedly connected to the top of the support rod 36. A pull plate 35 is fixedly connected to the side of the pin 34 away from the limiting plate 29. The pin 34 is made of alloy material to provide high fixing strength. The right pin 34 is slidably connected to the inside of the roller 3 16. The left pin 34 is slidably connected to the inside of the roller 1 14. The spring 33 is fixedly connected to the inside of the fixed shell 19. The spring 33 is sleeved on the outside of the pin 34. The sliding plate 32 is slidably connected to the right side of the fixed plate 31. The sliding plate 32 and the sliding block 30 abut against each other.
[0028] Working principle: When the motor 26 is started, the heating wire inside the arc-shaped drying chamber cover 8 is also activated. The motor 26 drives the transmission shaft 9 to rotate, and the transmission shaft 9 drives the gear 12 to rotate. The gear 12 meshes with the driven gear 17, so the driven gear 17 follows the gear 12 to rotate. The rotation of the driven gear 17 drives the second drum 15 to rotate. The second drum 15 drives the first drum 14, the third drum 16 and the cylindrical screen 20 to rotate. The first drum 14, the second drum 15, the third drum 16 and the cylindrical screen 20 are tilted to a certain extent. At the same time, there are turning plates 28 inside, which can allow the material to move along the tilt angle. Finally, the drying is completed and the material falls into the first collection box 24 and the second collection box 25.
[0029] By starting the motor 27, the transmission rod 22 is connected to the output end of the motor 27, so the transmission rod 22 rotates with the motor 27. At this time, the transmission rod 22 drives the turning plate 28 to turn the material. The dried material in the drum 16 is dispersed by the turning plate 28, avoiding agglomeration. At the same time, with the cooperation of the turning plate 28, the cylindrical screen 20 removes impurities from the material through the screen holes and falls into the second collection box 25. Larger and better quality materials cannot pass through the screen holes and eventually fall into the first collection box 24, thus realizing the screening function of the material.
[0030] By pulling the pull plate 35, the pin 34 moves away from the limit plate 29. The sliding block 30 moves with the pin 34. After the sliding block 30 moves a certain distance, the sliding plate 32 that was in contact with the sliding block 30 no longer contacts it. Under the action of gravity, the sliding plate 32 locks the sliding block 30 in place. At this time, the roller 14, roller 36 and roller 25 can be disassembled and separated. When installation is required, simply pull the sliding plate 32. At this time, the spring 33 returns the pin 34 to fix the roller 14, roller 36 and roller 25 again, thereby realizing the function of quick disassembly and installation.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
