[0002] Drying is an important step in tea processing and a tea dryer is required. A tea dryer for agricultural use disclosed in Chinese Patent No. 2018110987499 has a device for treating waste gas and dust, which is relatively energy-saving and environmentally friendly; the operation of the whole device has little impact on the taste and quality of the tea itself, that is, the drying quality of the dryer is relatively high. A dryer for tea production and processing disclosed in Chinese Patent No. 201921615005X can accelerate the flow of hot air inside the dryer through a jet pipe, and the tea is sprinkled and stirred by a stirrer, thereby promoting the contact area and frequency between the tea and the hot air, ensuring that the tea is evenly heated and fully dried, reducing the time required for tea drying, and improving the production and processing efficiency of the dryer. Through the heat preservation cover equipped with this dryer, the heat loss of the dryer can be effectively reduced, ensuring that the temperature required for tea drying is relatively maintained, and ensuring the quality of tea drying and processing production. A high-efficiency tea baking device for tea processing disclosed in Chinese Patent No. 202111622371X can drive a stirring rod to rotate by air through an extrusion component, so that after the tea is placed, the placement position at the bottom of the tea can be stirred, thereby improving the stirring efficiency of the tea during drying.

[0003] Although the above-mentioned tea dryers can effectively prevent damage to the tea when in use, there are still the following defects: First, the temperature of the hot air generated by the dryer is fixed, and the temperature cannot be flexibly adjusted to protect the tea quality and enhance adaptability; Second, through the stirring action, the friction and collision between the tea leaves and between the tea leaves and the stirrer will cause scratches, breakage or fragmentation on the surface of the tea leaves, thereby affecting the integrity and aesthetics of the tea leaves and unable to effectively prevent damage; Finally, different drying temperatures cannot be set in stages for step-by-step downward drying, but directly dried at a relatively high temperature, resulting in a decline in quality. Summary of the Invention

Detailed implementation manners

[0018] As Figures 1 to 10 shown, an anti-damage tea dryer for tea processing according to the present invention includes a drying box body 1, a first connecting frame 11, a first connecting frame 12, a third connecting frame 15, a mounting rack 8, a drying box 18, a heating component and a driving mechanism. The structure and working principle of the present invention will be described in detail below with reference to the accompanying drawings.

[0019] As Figures 1 to 10 shown, an anti-damage tea dryer for tea processing includes a drying box body 1. The drying box body 1 is of a cuboid structure. A sealing door 2 is provided on the front side of the drying box body 1. The sealing door 2 is hinged to the drying box body 1. To ensure the sealing performance, a sealing gasket is provided on the sealing door 2. Inside the drying box body 1, a plurality of connecting frames are arranged successively from top to bottom. As Figure 3 , Figure 5 shown, the left and right ends of the connecting frame have a rotating shaft 9. The rotating shaft 9 is rotatably connected to the drying box body 1. The rotating shafts 9 between every two adjacent connecting frames up and down are connected by a synchronization mechanism to achieve synchronous rotation. A driving mechanism for driving one of the rotating shafts 9 to swing reciprocally is provided on the drying box body 1. Specifically, there are three connecting frames, as Figure 2As shown, there are a first connecting frame 11, a second connecting frame 12, and a third connecting frame 15 arranged in sequence from top to bottom. Inside the first connecting frame 11, the second connecting frame 12, and the third connecting frame 15, there is a mounting frame 8. The middle part of the mounting frame 8 is hinged to the corresponding connecting frame (the first connecting frame 11, the second connecting frame 12, and the third connecting frame 15), as Figure 5 shown. Between both ends of the mounting frame 8 and the corresponding connecting frame (the first connecting frame 11, the second connecting frame 12, and the third connecting frame 15), there are sets of powerful springs 36. The number of powerful springs 36 in each group is four. The synchronization mechanism is a belt drive mechanism. The belt drive mechanism includes two belt pulleys 10 and a belt 13, as Figure 2 , Figure 3 shown. The belt pulley 10 is fixedly connected to the corresponding rotating shaft 9, and the belt 13 is arranged between the two belt pulleys 10. There is a belt drive mechanism between the rotating shafts 9 on the first connecting frame 11 and the second connecting frame 12, and there is another belt drive mechanism between the rotating shafts 9 on the second connecting frame 12 and the third connecting frame 15. As Figure 3 , Figure 4 shown, the driving mechanism includes a cylinder 6 and a rack 7. The cylinder 6 is fixed on the side wall of the upper part of the drying box body 1, the rack 7 is fixed on the piston rod of the cylinder 6, and the rack 7 is meshed and matched with the gear 4 at the end of the uppermost rotating shaft 9. When the piston rod of the cylinder 6 expands and contracts, the rack 7 reciprocates to drive the reciprocating rotation of the gear 4, and then drives the front and back swinging of the rotating shaft 9 and the connecting frame (the first connecting frame 11, the second connecting frame 12, and the third connecting frame 15). As Figure 8 shown, an ear plate 14 is fixed on the first connecting frame 11, and a rotating seat 35 is fixed in the middle of the mounting frame 8. The rotating seat 35 is rotatably connected to the ear plate 14, thereby realizing the hinge connection between the mounting frame 8 and the first connecting frame 11. Ear plates 14 are also provided on the second connecting frame 12 and the third connecting frame 15. The connection methods between the second connecting frame 12 and the corresponding mounting frame 8, and between the third connecting frame 15 and the corresponding mounting frame 8 are the same as the connection method between the mounting frame 8 and the first connecting frame 11.

[0020] The working principle of the driving mechanism is: when the piston rod of the cylinder 6 expands and contracts, it drives the up and down movement of the rack 7, and then drives the reciprocating rotation of the gear 4, that is, forward and reverse rotation, and then drives the front and back swinging of the connecting frame (the first connecting frame 11, the second connecting frame 12, and the third connecting frame 15). The working principle of the synchronization mechanism is: when the upper rotating shaft 9 rotates, the belt pulley 10 on the upper rotating shaft 9 rotates, and then the belt 13 that cooperates with it moves, and then drives the belt pulley 10 on the lower rotating shaft 9 to rotate, and then the lower rotating shaft 9 rotates synchronously with the upper rotating shaft 9.

[0021] When the first connecting frame 11, the second connecting frame 12, and the third connecting frame 15 swing back and forth, they drive the back-and-forth swing of the mounting frame 8 hinged thereto. While the mounting frame 8 swings back and forth with the connecting frame, the mounting frame 8 also swings back and forth relative to the connecting frame. When the two ends of the mounting frame 8 touch the strong spring 36, the mounting frame 8 undergoes rocking vibration.

[0022] As Figure 6 shown, the inner wall of the mounting frame 8 has a heating plate 5. The heating plate 5 has low-temperature heating tubes 16 and high-temperature hot gas tubes 17 that work independently or / and simultaneously. The low-temperature heating tubes 16 and the high-temperature hot gas tubes 17 constitute a drying assembly. The mounting frame 8 has a drying box 18 for placing tea leaves. A control panel 3 is provided on the sealing door 2. The control panel 3 is electrically connected to the low-temperature heating tubes 16 and the high-temperature hot gas tubes 17 to control the working states of the low-temperature heating tubes 16 and the high-temperature hot gas tubes 17. Both the low-temperature heating tubes 16 and the high-temperature hot gas tubes 17 are in a continuous zigzag shape, and the high-temperature hot gas tubes 17 are located inside the low-temperature heating tubes 16. By operating the control panel 3, the working states of the low-temperature heating tubes 16 and the high-temperature hot gas tubes 17 are controlled. The drying box 18 is made of metal. The bottom of the drying box 18 has air jet nozzles 34. The air jet nozzles 34 are connected to the high-temperature hot gas tubes 17 through connecting pipes. Both ends of the connecting frame (the first connecting frame 11, the second connecting frame 12, and the third connecting frame 15) have air bags 37, as Figure 5 shown, and the air bags 37 are located between four groups of strong springs 36. The air bags 37 are connected to the high-temperature hot gas tubes 17 through connecting pipes. The low-temperature heating tubes 16, the high-temperature hot gas tubes 17, the connecting pipes, the air bags 37, and the air jet nozzles 34 constitute a blowing assembly.

[0023] The working principle of the blowing assembly is as follows: During the process of the driving mechanism driving the connecting frame (the first connecting frame 11, the second connecting frame 12, and the third connecting frame 15) to swing back and forth, the mounting frame 8 swings around the hinge point with the connecting frame (the first connecting frame 11, the second connecting frame 12, and the third connecting frame 15). The two ends of the mounting frame 8 squeeze the air bags 37, forcing the high-temperature gas in the high-temperature hot gas tubes 17 to be ejected through the air jet nozzles 34 into the drying box 18, blowing hot air on the tea leaves in the drying box 18, thereby realizing the drying of the tea leaves.

[0024] To achieve step-by-step drying / sequential drying of the tea leaves, as Figure 5 、 Figure 7 shown, the bottom of the drying box 18 includes two bottom plates 19. One end of the bottom plates 19 is hinged to the drying box 18. The side wall of the drying box 18 has an opening and closing mechanism. The opening and closing mechanism drives the bottom plates 19 to swing relative to the drying box 18. When the other ends of the two bottom plates 19 contact, they form the bottom of the drying box 18. When the other ends of the two bottom plates 19 face downward, the bottom of the drying box 18 opens. As Figure 7 、 Figure 10As shown in the figure, the opening and closing mechanism includes a micro-motor 22, a connecting plate 23, a fixed shaft 24, a moving plate 25, a hinge shaft 26 and a moving wheel 27. The micro-motor 22 is fixed on the side wall of the drying box 18. One end of the connecting plate 23 is fixedly connected to the output shaft of the micro-motor 22 through a coupling. The fixed shaft 24 is rotatably connected to the other end of the connecting plate 23. The moving plate 25 is rotatably connected to the fixed shaft 24 and the moving plate 25 is hinged to the drying box 16 through the hinge shaft 26. The moving wheel 27 is rotatably installed at one end of the moving plate 25. The moving plate 25 is a telescopic structure, that is, the length of the moving plate 25 can be adjusted. A track plate 20 is fixed on the bottom plate 19. The track plate 20 has a limit groove 21. The moving wheel 27 is located in the limit groove 21 and moves along the limit groove 21.

[0025] The working principle of the opening and closing mechanism is as follows: When the micro-motor 22 is started, the connecting plate 23 rotates accordingly. During the rotation of the connecting plate 23, the fixed shaft 24 is driven to rotate, which in turn drives the moving plate 25 to swing around the hinge shaft 26, and the moving plate 25 itself elongates or shortens; during the movement of the moving plate 25, the movement of the moving wheel 27 is driven, and the moving wheel 27 rolls along the limit groove 21, which in turn drives the movement of the track plate 20. The movement of the track plate 20 drives the bottom plate 19 to swing relative to the drying box 18, so that the two bottom plates 19 approach each other until they come into contact, or separate to open the bottom of the drying box 18 to unload the tea. Each drying box 18 is provided with an opening and closing mechanism, and the opening and closing mechanisms on several drying boxes 18 work independently. After the tea in the upper drying box 18 is dried in the first stage / step under the action of the drying component on the corresponding mounting rack 8, the bottom plate 19 at the bottom of the upper drying box 18 is opened through the opening and closing mechanism on the upper drying box 18, so as to unload the tea in the upper drying box 18. At this time, the tea falls into the lower drying box 18. The tea in the lower drying box 18 is dried in the second stage / step under the action of the drying component on the lower mounting rack 8. That is: After the tea in the drying box 18 inside the first connecting frame 11 is dried in the first stage / step under the action of the corresponding drying component, the bottom plate 19 of the corresponding drying box 18 is opened through the opening and closing mechanism, so that the tea in the drying box 18 inside the first connecting frame 11 falls into the drying box 18 inside the second connecting frame 12. The tea in the drying box 18 inside the second connecting frame 12 is dried in the second stage / step under the action of the corresponding drying component. After the second stage / step of drying is completed, the bottom plate 19 of the corresponding drying box 18 is opened through the opening and closing mechanism, so that the tea in the drying box 18 inside the second connecting frame 11 falls into the drying box 18 inside the third connecting frame 15. The tea in the drying box 18 inside the third connecting frame 12 is dried in the third stage / step under the action of the corresponding drying component until the third stage / step of drying is completed, thus realizing staged / step-by-step drying.

[0026] To facilitate the addition of tea leaves into the drying box 18 and the reset of the drying box 18, the mounting frame 8 is slidably connected to the drying box 18 and there is an elastic connecting member between the two. As Figure 5 , Figure 9 shown, the elastic connecting member includes a pulley 29, a collecting seat 31 and a scroll self-rotating spring 33. The collecting seat 31 is fixed on the mounting frame 8. A winding rod 30 is rotatably mounted on the collecting seat 31. There is a scroll self-rotating spring 33 between the winding rod 30 and the collecting seat 31. After an external force drives the winding rod 30 to rotate relative to the collecting seat 31, the scroll self-rotating spring 33 stores energy. After the external force is removed, the scroll self-rotating spring 33 releases elastic potential energy, and the winding rod 30 rotates in the opposite direction relative to the collecting seat 31. A connecting belt 32 is wound around the winding rod 30. One end of the connecting belt 32 is fixedly connected to the outer wall of the winding rod 30, and the other end of the connecting belt 32 is fixedly installed on the pulley 29. The pulley 29 is rotatably mounted on the side wall of the drying box 18 and is in rolling cooperation with the chute 28 on the mounting frame 8, that is, the pulley 29 rolls in the chute 28.

[0027] The working principle of the elastic connecting member is as follows: When the drying box 18 is opened, the drying box 18 is pulled outwards. At this time, the pulley 29 rolls in the chute 28, and the connecting belt 32 is continuously wound around the pulley 29, while the connecting belt 32 on the winding rod 30 gradually decreases. The connecting belt 32 pulls the winding rod 30 to rotate, and the scroll self-rotating spring 33 stores energy. After adding tea leaves into the drying box 18, the drying box 18 is released. At this time, the scroll self-rotating spring 33 releases elastic potential energy, causing the winding rod 30 to rotate and wind the connecting belt 32, thereby driving the pulley 29 to rotate in the opposite direction, and then driving the drying box 18 to retract into the mounting frame 8.

[0028] In the present invention, by providing a low-temperature heating tube and a high-temperature hot gas pipe, the temperature can be flexibly adjusted, the drying efficiency can be improved, the quality of the tea leaves can be protected and the adaptability can be enhanced. Moreover, in cooperation with the setting of the driving mechanism, the tea leaves are dried in a cradle manner to prevent damage to the tea leaves during the drying process. And by setting a rotating seat, a strong spring and an airbag, vibration can be applied to the tea leaves during drying to prevent the tea leaves from piling up. At the same time, a plurality of connecting frames are arranged in a top-down manner, and different drying temperatures are set in stages in the drying boxes of different connecting frames to perform step-by-step downward drying.
