The first hole groove structure 421 is a first through hole provided on the first connecting arm 42, and the second hole groove structure 431 is a second through hole provided on the second connecting arm 43. The installation of the first spring 441 can be facilitated by simply hooking the first hook 442 into the first through hole and the second hook 443 into the second through hole, so that the first connecting arm 42 can be connected to the second connecting arm 43 through the first spring 441 to limit the free rotation of the first connecting arm 42 relative to the second connecting arm 43.

[0041] Please refer to Figure 1 and Figure 2In some embodiments, a first hinge seat 45 is provided at one end of the first connecting arm 42 close to the flip plate 41, and an end of the second connecting arm 43 away from the rotating shaft 31 is rotatably connected to the first hinge seat 45 through a first pivot.

The length direction of the strip buffer sheet 48 is parallel to the axial direction of the rotating shaft 31. The strip buffer sheet 48 is provided with a plurality of strip holes at intervals along its length direction. The length direction of the strip holes is perpendicular to the axial direction of the rotating shaft 31. The position of the strip buffer sheet 48 is adjusted by adjusting the tightness of the fastening bolt 49 and then moving the strip buffer sheet 48 along the length direction of the strip holes, so that the strip buffer sheet 48 maintains sliding contact with the inner wall of the inner body of the pot body 2 without being too tight, which can play a further buffering role and prevent the flip plate 41 from scratching the pot body 2.

[0045] Please refer to Figure 1 and Figure 2In some embodiments, the strip buffer sheet 48 is bent on one side away from the flip plate 41 to form a sliding contact portion for slidingly contacting the inner wall of the pot body 2 of the tea withering machine.

In addition, the plurality of drop openings 7 are arranged at equal intervals along the length direction of the flip plate 41, and the tea leaves scraped up by the flip plate 41 can fall back into the pot body 2 through the plurality of drop openings 7 in a dispersed manner, so that the tea leaves can be fully and evenly spread, so that the tea leaves can be more evenly dehydrated and sterilized. It should be noted that the mouth area of ​​the drop opening 7 is larger than the area of ​​the tea leaves, so that the tea leaves can smoothly fall back into the pot body 2 through the drop opening 7.

[0047] Please refer to Figure 3 and Figure 4 The embodiment of the utility model also provides a tea-tea-fixing machine, which includes the flip-type tea-tea-stirring mechanism provided in any of the above embodiments. Since the tea-tea-fixing machine has all the technical features of the flip-type tea-tea-stirring mechanism provided in any of the above embodiments, it has the same technical effect as the flip-type tea-tea-stirring mechanism.

[0048] Please also read Figure 3 and Figure 4 The tea-withering machine provided by the embodiment of the utility model comprises a frame 1, a pot body 2, a heater and a flip-type tea-leaf stirring mechanism. The pot body 2 is arranged on the frame 1. The pot body 2 and / or the frame 1 are provided with a heater. When the heater is powered on, the pot body 2 can be heated so that the temperature (200°C to 300°C) matching the withering and dehydration of fresh tea leaves is reached in the pot body 2. The pot body 2 is a semicircular groove pot body 2 arranged horizontally. The flip-type tea-leaf stirring mechanism is used to stir and turn over the tea leaves in the pot body 2, solving the problem that the withering and frying at a temperature of 200°C requires a long frying time, and the withering and frying at a temperature of 300°C consumes a lot of energy, effectively shortens the tea-withering and frying time, and improves the tea-withering and frying efficiency. Specifically, the flip-type tea-leaf stirring mechanism is rotatably arranged on the frame 1, the flip-type tea-leaf stirring mechanism is located above the pot body 2, and at least part of the flip-type tea-leaf stirring mechanism 3 extends into the pot body 2, and the temperature in the pot body 2 is controlled at 200°C to 250°C.

When the driving motor drives the rotating shaft 31 to rotate, the rotating shaft 31 can drive the flip plate 41 to flip periodically around the rotating shaft 31, so that the flip plate 41 can flip and stir the tea leaves in the pot body 2, and the stirred tea leaves are thrown up by the flip plate 41 to realize the action of simulating manual leaf throwing. While the tea leaves are withering, the tea leaves can be continuously turned over and stir-fried, thereby achieving the effect of quickly, efficiently and evenly withering and losing water to the tea leaves.

[0050] Please refer to Figure 3 In some embodiments, the tea-withering machine further includes a protective cover 6 covering the mouth of the pot body 2, and the protective cover 6 blocks the tea leaves, so that the tea leaves thrown up by the flipping mechanism can quickly fall back into the pot body 2, and the tea leaves thrown up by the flipping mechanism are prevented from being thrown out of the pot body 2. In addition, the protective cover 6 is provided with an observation port for observing the tea leaves in the pot body 2, and the withering and frying status of the tea leaves can be observed through the observation port.

[0051] Further references Figure 4 and Figure 5The tea-tea-fixing machine provided by the embodiment of the utility model also includes a breaking component 5, which is used to break up the tea balls gathered in the pot body 2 of the tea-tea-breaking machine. Specifically, the breaking component 5 includes a rotating plate 51, a plurality of breaking teeth 52, a third connecting arm 53, a fourth connecting arm 54 and a second elastic member 55, wherein the plurality of breaking teeth 52 are arranged on the rotating plate 51, the third connecting arm 53 is connected to the rotating plate 51, the fourth connecting arm 54 is connected to the rotating shaft 31, the second elastic member 55 is connected to the third connecting arm 53 and the fourth connecting arm 54 respectively, and the second elastic member 55 is in a natural state of neither compression nor extension, the end of the third connecting arm 53 close to the rotating plate 51 is rotationally connected to the end of the fourth connecting arm 54 away from the rotating shaft 31, the first end of the second elastic member 55 is connected to the end of the third connecting arm 53 away from the rotating plate 51, and the second end of the second elastic member 55 is connected to the end of the fourth connecting arm 54 close to the rotating shaft 31. When using the tea withering machine provided in the embodiment of the utility model to break up the tea leaves, the driving motor drives the rotating shaft 31 to rotate at a set speed, and the rotating shaft 31 drives the rotating plate 51 and the breaking teeth 52 on the rotating plate 51 to rotate. The breaking teeth 52 can break up the tea clumps gathered in the pot body 2 during the rotation process. Since one end of the third connecting arm 53 close to the rotating plate 51 is rotationally connected to the end of the fourth connecting arm 54 away from the rotating shaft 31, the first end of the second elastic member 55 is connected to the end of the third connecting arm 53 away from the rotating plate 51, and the second end of the second elastic member 55 is connected to the end of the fourth connecting arm 54 close to the rotating shaft 31, and the second elastic member 55 is in a natural state of neither compression nor extension. At the moment when the breaking teeth 52 hit the agglomerated tea balls, the third connecting arm 53 is rotated by a small angle relative to the fourth connecting arm 54 after being subjected to force, and the elastic member is immediately in a stretched state, which can play a good buffering role and effectively avoid the phenomenon that the breaking teeth 52 violently hit the agglomerated tea balls and the tea leaves are hit too hard, thereby effectively preventing the tea leaves from being damaged or broken, which is beneficial to improving the quality of tea processing.

[0052] The tea withering machine provided by the embodiment of the utility model, compared with the prior art, only needs to drive the rotating shaft 31 to rotate by the driving motor, and the agglomerated tea balls can be broken up by the breaking teeth 52 on the rotating plate 51 during the rotation process. At the moment when the breaking teeth 52 strike the agglomerated tea balls, under the pulling force of the second elastic member 55, the third connecting arm 53 connected to the rotating plate 51 can be rotated by a small angle relative to the fourth connecting arm 54 connected to the rotating shaft 31 after being subjected to force, and the elastic member is in a stretched state, which can play a good buffering role and reduce the instantaneous impulse of the breaking teeth 52 on the tea leaves, effectively avoiding the breaking teeth 52 from violently striking the agglomerated tea balls and causing the tea leaves to strike too hard, thereby effectively preventing the tea leaves from being damaged or broken, which is conducive to improving the quality of tea processing. After the breaking teeth 52 contact the agglomerated tea balls, under the pulling force of the elastic member, the third connecting arm 53 and the fourth connecting arm 54 are restored to the initial position, so that the breaking teeth 52 can evenly break up the tea leaves.

[0053] Please refer to Figure 1 , Figure 4 and Figure 5 In some embodiments, the breaking teeth 52 are breaking pieces arranged on the side of the rotating plate 51 away from the third connecting arm 53. The breaking pieces are rectangular, and the length direction of the breaking pieces is perpendicular to the axial direction of the rotating shaft 31. The agglomerated tea balls are evenly broken up by the serrated breaking pieces distributed on the rotating plate 51. Since the serrated breaking pieces are conducive to reducing the instantaneous impact force on the tea balls, it is conducive to preventing the tea leaves from being damaged or broken. It should be noted that the breaking teeth 52 can be integrally formed with the rotating plate 51.

[0054] In some embodiments, the breaking sheet is an elastic metal sheet, which may be, but is not limited to, a steel sheet or an aluminum sheet. Since the steel sheet or the aluminum sheet has a certain elasticity when it is thin, when the breaking sheet strikes the agglomerated tea balls, it is helpful to reduce the instantaneous impact force on the tea balls, and is helpful to prevent the tea leaves from being damaged or broken.

[0055] Please refer to Figure 1 , Figure 4 and Figure 5 In some of the embodiments, in order to improve the efficiency and uniformity of breaking up the tea balls, a plurality of breaking pieces are arranged at intervals along the axial direction of the rotating shaft 31, and the distance between two adjacent breaking pieces is equal.

[0056] Please refer to Figure 1 , Figure 4 and Figure 5 In some of the embodiments, the width of the breaking up piece is equal to the distance between two adjacent breaking up pieces, which can further improve the efficiency and uniformity of breaking up the tea balls.

[0057] Please refer to Figure 1 , Figure 4 and Figure 5 In some embodiments, the ratio of the length of the breaking piece to the width of the breaking piece is (2-5):1. When the breaking piece strikes the agglomerated tea balls, it is helpful to reduce the instantaneous impact force on the tea balls and prevent the tea leaves from being damaged or broken.

[0058] Please refer to Figure 1 , Figure 4 and Figure 5 In some embodiments, the second elastic member 55 includes a second spring 551, a third hook disposed at a first end of the second spring 551, and a fourth hook disposed at a second end of the second spring 551. The end of the third connecting arm 53 away from the flip plate is provided with a third hole structure for the third hook to hook, and the end of the fourth connecting arm 54 close to the rotating shaft 31 is provided with a fourth hole structure for the fourth hook to hook. The third hole structure is a first through hole disposed on the third connecting arm 53, and the fourth hole structure is a second through hole disposed on the fourth connecting arm 54. The installation of the second spring 551 can be facilitated by simply hooking the third hook into the first through hole and hooking the fourth hook into the second through hole, so that the third connecting arm 53 can be connected to the fourth connecting arm 54 through the second spring 551 to limit the free rotation of the third connecting arm 53 relative to the fourth connecting arm 54.

[0059] Please refer to Figure 1 , Figure 4 and Figure 5 In some embodiments, the end of the third connecting arm 53 close to the flip plate is provided with a second hinge seat 56, and the end of the fourth connecting arm 54 away from the rotating shaft 31 is rotatably connected to the second hinge seat 56 through the first pivot. At the moment when the scattering teeth 52 strike the agglomerated tea balls, under the pulling force of the elastic member, the third connecting arm 53 connected to the rotating plate 51 can be rotated by a small angle relative to the fourth connecting arm 54 connected to the rotating shaft 31 after being subjected to force, which can play a good buffering role and reduce the instantaneous impulse of the scattering teeth 52 on the tea leaves. The end of the third connecting arm 53 away from the flip plate is provided with a second abutting seat 57 for abutting the fourth connecting arm 54, and the middle position of the fourth connecting arm 54 in the length direction abuts against the second abutting seat 57, which can enhance the stability of the connection between the third connecting arm 53 and the fourth connecting arm 54 and prevent the third connecting arm 53 from rotating in the opposite direction of the rotation relative to the fourth connecting arm 54 when striking the tea balls.

[0060] Please refer to Figure 1 , Figure 4 and Figure 5In some embodiments, a second clamp 58 is provided at one end of the fourth connecting arm 54 close to the rotating shaft 31, and the second clamp 58 is used to be detachably connected to the rotating shaft 31. The fourth connecting arm 54 is fixedly connected to the rotating shaft 31 by the second clamp 58, which can enhance the stability of the connection between the fourth connecting arm 54 and the rotating shaft 31 on the one hand, and facilitate the disassembly and replacement of the fourth connecting arm 54 and the rotating shaft 31 on the other hand.
