Description

Technical Field

[0001] This utility model relates to the field of tea picking, specifically a new type of tea picking machine with a zoned cutting and harvesting device and a young bud protection device. Background Technology

[0002] As the world's largest tea-drinking nation, my country's tea industry has extremely stringent requirements for the uniformity of raw materials—from the standard length of buds and leaves to the specifications for their shape, forming a quality control threshold for tea raw materials rarely seen in the world. While traditional manual harvesting can achieve basic grading, differences in individual techniques still lead to inconsistent bud and leaf sizes. Coupled with the reality of rising labor costs year after year, the model relying on precise manual control of bud and leaf length is becoming increasingly unsustainable in large-scale production. The standardization dilemma in tea harvesting is forcing a shift towards mechanization.

[0003] With the development of mechanized tea harvesting, reciprocating tea harvesting machines are now available on the market. For example, the tea harvesting machine disclosed in CN108207313A includes a vehicle body with a walking mechanism at the bottom, a column on the vehicle body, and a shear unit mounted on a shear support. The shear unit is arranged in an arc shape that matches the curved shape of the tea tree crown A. The shear support is connected to the column, and a pneumatic blowing pipe and a tea collection bag are mounted on the shear support. The airflow from the pneumatic blowing pipe is directed towards the opening of the tea collection bag. The shear unit is located between the air outlet of the pneumatic blowing pipe and the opening of the tea collection bag. The tea leaves cut by the shear unit are immediately blown towards the opening of the tea collection bag by the airflow from the pneumatic blowing pipe. In this way, the tea leaves are collected into the tea collection bag in a timely manner while the tea harvesting machine is moving and cutting. After the tea collection bag has collected a suitable amount of tea leaves, it can be replaced or the tea leaves in the bag can be emptied and transferred.

[0004] For example, the electric tea-picking machine disclosed in CN102783309A has a specific structure in which the upper output shaft of the motor is fixed to the impeller of the fan, the lower output shaft of the DC motor is fixed to the central shaft of the crankshaft, the two eccentric pins of the crankshaft are movably connected to the large end of the upper and lower connecting rods respectively, and the small end of the upper and lower connecting rods are movably connected to the upper and lower blades respectively. Alternatively, the lower output shaft of the DC motor is set as an external gear shaft, which meshes with the internal gear of an inner and outer diameter gear, and the external gear of the inner and outer diameter gear meshes with the outer diameter edge gear of the crankshaft.

[0005] The above-mentioned technical solution involves cutting off everything that enters the shearing range and sending it indiscriminately into the leaf collection warehouse. The tea leaves that are trimmed include a mixture of raw materials such as buds, leaves, single leaves, broken pieces, old leaves, and old tea stems. The broken pieces, old leaves, and old tea stems that are trimmed off are not suitable for use and need to be sorted later. This increases the cost of tea processing and also wastes energy.

[0006] Therefore, it is necessary to design a new type of tea-picking machine with a zoned cutting and harvesting and bud protection device to assist in the efficient harvesting of suitable buds and leaves during machine picking, protect unsuitable buds, and help the machine-cut buds and leaves enter the leaf collection bag more effectively along the feeding port, automatically separating cut fragments, broken stems, etc., improving the uniformity of tea picking, and solving the problem of machine cutting damaging buds in the existing equipment. Utility Model Content

[0007] The purpose of this utility model is to provide a new type of tea-picking machine with a partitioned cutting and harvesting and young bud protection device, which can help the tea leaves enter the transport channel of the tea-picking machine better during tea picking, improve the uniformity of bud and leaf picking and the young bud protection rate, so as to solve the existing technical defects and unmet technical requirements.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a novel tea-picking machine with a zoned cutting and harvesting mechanism and a young bud protection device, comprising:

[0009] Several bases, with a conveying channel formed between adjacent bases;

[0010] A swaying leaf assembly is disposed at the front end of the base and is rotatably connected to the base;

[0011] A cutting assembly, wherein the cutting assembly is disposed below and connected to a plurality of bases;

[0012] A bud protection component is connected to a base and is positioned above or below the cutting component. The portion of the bud protection component located below the base extends forward to the front of the cutting component.

[0013] The swinging leaf-picking component swings to comb the tea leaves to both sides, helping them enter the conveying channel. The bud protection component blocks some buds to prevent them from being cut by the cutting component.

[0014] Further explanation is needed regarding the above-mentioned content, in which a transmission component is provided below the base, the transmission component takes the form of a conveyor belt, and the conveying channel is specifically formed between two adjacent transmission components. The front end of the conveying channel has a feed inlet formed by the two transmission components, and the rear end of the conveying channel has a discharge outlet formed between the two transmission components. The bud protection component and the cutting component are located below the transmission components. In addition, regarding the position of the cutting component in this application, the cutting component is provided below several bases, or only below the feed inlet, that is, the cutting component is not provided below the base or the circular blade and cutting teeth described below are not provided.

[0015] Preferably, the bud protection component includes:

[0016] A support frame, which is connected to the base and is positioned above or below the cutting assembly;

[0017] A bud-preserving board is provided at intervals on a support frame and only below each base. One end of the bud-preserving board is connected to the support frame, and the other end extends away from the support frame, extending at least to the front of the cutting component, so as to cover the front end of the cutting component and prevent the buds located below the base from being cut by the cutting component.

[0018] In this application, the statement that the bud-preserving plate is only located below the base can be understood as the bud-preserving plate being located entirely below the base. It can extend in the length direction of the base, or in the vertical direction, or in either of the above two ways to prevent tilting after assembly. However, the bud-preserving plate cannot extend in the width direction of the base, that is, the width of the bud-preserving plate cannot exceed the width of the transmission component, and it does not obstruct tea leaves entering the conveying channel or below the conveying channel.

[0019] Preferably, the cutting assembly includes a blade holder, a first circular blade, and a second circular blade. The blade holder is connected to a base and is located below several bases. The first and second circular blades are periodically distributed on the blade holder along its length, and the first and second circular blades are rotatable on the blade holder.

[0020] The first and second circular blades rotate, cutting the tea leaves that enter the conveying channel.

[0021] In this application, the structure of mounting the blade on the tool holder described above is a common technology in the prior art. For example, the blade can be mounted on a rotating shaft, and the tool holder has a hole for mounting the rotating shaft. The rotating shaft passes through this hole and is mounted on the tool holder. The rotating shaft can rotate on the tool holder, and the rotating shaft is connected to the output end of a drive motor. The rotating shaft is driven to rotate by the drive motor, thereby causing the blade to rotate. This application does not specifically limit the driving of the blade or the connection method between the blade and the tool holder.

[0022] Preferably, the first circular blade and the second circular blade partially overlap in the vertical direction or are tangent in the horizontal direction.

[0023] In this application, the structure of the first and second circular blades can be understood as follows: Firstly, there is partial overlap in the vertical direction. This can be understood as the first and second circular blades being located on different layers in the vertical direction, with some overlap in their cutting edges or contours. In terms of quantity, the two types of blades can have a one-to-one correspondence, a one-to-many relationship, or a many-to-many relationship. In the one-to-many or many-to-many case, the more numerous blades are spaced apart in the vertical direction, and the other type of blade is located in the space between the spaced blades in the vertical direction, with partial overlap. Regarding the tangent contours, this can be understood as the two types of blades being located in the same layer, and their cutting edges being tangent to each other. Furthermore, the layer mentioned above can be understood as the plane on which the blades are located. It should be further noted that the two types of blades mentioned above are "periodically" distributed on the tool holder regarding the vertical overlap. This can be understood as the combination of the two types of blades described above in this paragraph being a cyclical group. Although it is distributed cyclically in the form of groups, the distribution between groups must also conform to the explanation of the cyclical distribution of the two types of blades within the cyclical group in this paragraph. For example, a cyclical group consists of one first circular blade and two second circular blades. The overlapping part in the vertical direction of the group, from top to bottom, is the second circular blade, the first circular blade, and the second circular blade. Then, a first circular blade in an adjacent group must also have an overlapping part between the two second circular blades in the above group. That is, the blades in the cyclical group are arranged in the horizontal direction as one first circular blade and two second circular blades. The connection relationship between the two groups is: the two second circular blades distributed at intervals in the vertical direction have an overlapping part on one side with the first circular blade in the same group, and the other side also has an overlapping part with the first circular blade in the adjacent group.

[0024] Preferably, the cutting assembly is located below the base. The cutting assembly includes a first blade holder and a second blade holder. The first blade holder abuts against the second blade holder. The first blade holder is evenly provided with a plurality of first blade teeth, and the second blade holder is evenly provided with a plurality of second blade teeth. The first blade teeth and the second blade teeth are spaced apart in the horizontal direction. The first blade holder and the second blade holder can slide relative to each other, so that the spaced first blade teeth and the second blade teeth overlap in the vertical direction or exchange positions in the horizontal direction to complete the cutting of the tea leaves.

[0025] Preferably, two transmission components are symmetrically arranged on the lower end face of each base, and a swinging leaf assembly is arranged on the upper end face of each base, forming a feeding channel between the transmission components on adjacent bases.

[0026] Preferably, the transmission assembly includes a transmission belt and a plurality of transmission pulleys. The transmission belt is sleeved on the plurality of transmission pulleys. The transmission pulleys are rotatably connected to the base. When the transmission pulleys rotate, they can drive the transmission belt to rotate.

[0027] A conveying channel is formed between the two belts on the adjacent bases, which can transport tea leaves to the leaf collection bin located at the rear end of the conveying channel.

[0028] Preferably, at least one of the transmission pulleys located at the front end of the base is provided with an eccentric wheel portion.

[0029] In this application, it is necessary to further explain that the eccentric wheel part mentioned above is one type of cam structure, while in this application, the eccentric wheel part is only one type. It can be understood that the oscillation of the oscillating leaf assembly in this application is achieved through a cam structure.

[0030] Preferably, the oscillating leaf assembly includes:

[0031] A swaying blade component, comprising a free end and a rotating end, wherein the rotating end is disposed on the upper surface of the base, and the free end extends away from the base to the front of the base;

[0032] A rotating shaft is mounted on a base, and the free end is sleeved outside the rotating shaft and is capable of rotating relative to the rotating shaft;

[0033] A stopper is disposed between the free end and the rotating end of the oscillating leaf element, and extends downward through the base to abut against the eccentric wheel portion on the transmission belt pulley.

[0034] A reset member is disposed on the base and abuts against the side of the transmission belt pulley on the abutment that is away from the part on which the eccentric wheel is disposed.

[0035] In this application, the above content can be understood as follows: the reset member and the eccentric wheel are located on both sides of the abutment. The reset member can be in the form of a reset member or a cam structure adapted to the eccentric wheel. In addition, as mentioned above, the lower end of the abutment passes through the base. Therefore, it should be further explained that in this application, the swing of the free end is obviously achieved by moving the abutment. Therefore, the hole or groove provided on the base through which the abutment passes is sufficient to provide enough space for the movement of the abutment.

[0036] Preferably, the support frame is located below the cutting assembly, and the bud-preserving plate extends upward at an angle away from the support frame, covering the front end portion of the cutting assembly located directly below the base, and extending to below the oscillating leaf-removing component.

[0037] Alternatively, one end of the bud-preserving plate can be rotatably connected to the support frame, while the other end extends upward at an angle, covering the front part of the cutting assembly located directly below the base, and then connecting to the front end of the swinging leaf-dispensing component, swinging with the swinging leaf-dispensing component.

[0038] Preferably, the leaf collection chamber is located below the rear end of the transmission component, and there is a gap between the leaf collection chamber and the rear end of the transmission component.

[0039] In this application, the distance between the leaf collection chamber and the transmission component is at least greater than or equal to the distance between the bottom of the transmission component and the cutting component.

[0040] Preferably, the base is provided with a swing limiter to prevent the swing amplitude of the free end of the swing blade.

[0041] Compared with the prior art, the beneficial effects of this utility model are:

[0042] 1. In this application, the oscillating leaf-dispersing component is used to comb and move the tea leaves to both sides, which helps to better separate the tea leaves and allow them to enter the conveyor channel along the feeding port during tea picking, thereby improving the efficiency of tea picking and sorting. Furthermore, with the assistance of the oscillating leaf-dispersing component, when the equipment moves forward during use, the tea leaves are prevented from being pushed over or bent, making them easier for the feeding component to hold, thus improving harvesting efficiency and preventing missed picking.

[0043] 2. In this application, the young bud protection component is used to cut and harvest suitable buds and leaves, while avoiding damage to young buds on the tea tree that cannot be picked, thereby shortening the secondary harvesting cycle and reducing the impact on tea yield.

[0062] The following will refer to the appendix in the embodiments of this utility model. Figure 1-17The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0063] In the description of this utility model, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0064] Please see Figure 1-17 Embodiments of this utility model:

[0065] Example 1:

[0066] like Figure 1-2 As shown: including:

[0067] A plurality of bases 4, wherein a conveying channel 1 is formed between adjacent bases 4;

[0068] A swinging leaf assembly is disposed at the front end of the base 4 and is rotatably connected to the base 4.

[0069] A cutting assembly is disposed below and connected to a plurality of bases 4;

[0070] A bud protection component is connected to the base 4 and is positioned above or below the cutting component. The portion of the bud protection component located below the base 4 extends forward to the front of the cutting component.

[0071] The swinging leaf-picking component swings to comb the tea leaves to both sides, helping them enter the conveying channel 1. The bud protection component blocks some buds to prevent them from being cut by the cutting component.

[0072] In this embodiment, by setting up the swing leaf-picking component, the tea leaves can be actively combed to both sides during tea picking, so that the tea leaves can smoothly enter the conveying channel 1 for centralized picking, thereby improving the efficiency of tea picking and sorting. This avoids the phenomenon that the tea leaves are pushed down and bent due to dense tea leaves, making them difficult to be held by the feeding unit, which in turn affects the harvesting and cleaning rate.

[0073] By using a bud protection component, suitable buds and leaves can be cut and harvested, while avoiding damage to buds that cannot be picked from the tea tree, thereby shortening the secondary harvesting cycle and reducing the impact on tea yield.

[0074] The cutting assembly includes a blade holder, a first circular blade 3 and a second circular blade 11. The blade holder is connected to a base 4 and is located below several bases 4. The first circular blade 3 and the second circular blade 11 are periodically distributed on the blade holder along the length direction of the blade holder, and the first circular blade 3 and the second circular blade 11 can rotate on the blade holder.

[0075] The first circular blade 3 and the second circular blade rotate, which can cut the tea leaves that enter the conveying channel 1.

[0076] like Figure 8 As shown: the first circular blade 3 and the second circular blade 11 partially overlap in the vertical direction or are tangent in the horizontal direction.

[0077] In this embodiment, the first circular blade 3 and the second circular blade 11 are arranged such that their horizontal contours are tangent, and the order is first circular blade 3, then second circular blade 11. The connection between groups (smallest cycle units) in the periodic cyclic distribution is also tangent; that is, the right side of the first circular blade 3 is tangent to the left side of the second circular blade 11, and the right side of the second circular blade 11 is tangent to the left side of the first circular blade 3 in the next "cycle group". In this embodiment, the arrangement of the two circular blades can also be understood as follows: each first circular blade 3 is tangent to the second circular blade 11 on both sides, and each second circular blade 11 is tangent to the first circular blade 3 on both sides. The tangent points of the two circular blades are located directly below the conveying channel 1.

[0078] The bud protection component includes:

[0079] A support frame, which is connected to the base 4, is disposed above or below the tool holder;

[0080] The bud preservation board 20 is spaced apart on the support frame and is only located below each base 4. One end of the bud preservation board 20 is connected to the support frame, and the other end extends away from the support frame, extending at least to the front of the cutting component, to prevent the buds located below the base 4 from being cut by the cutting component.

[0081] In this embodiment, the support frame is set above the blade holder. The front end of the bud preservation plate 20 extends to the front of the blade, then bends downward to a position lower than the lower end face of the blade, and then extends towards the support frame to the bottom of the blade. The blade directly below the base 4 is covered in a semi-enclosed manner, which prevents some young buds from being damaged by the cutting component without affecting the tea leaves from entering the conveying channel 1.

[0082] like Figure 1-4As shown: Two transmission components 7 are symmetrically arranged on the lower end face of each base 4, and a swing blade assembly is arranged on the upper end face of each base 4. A feeding channel is formed between the transmission components 7 on adjacent bases 4.

[0083] like Figure 3-5 As shown: The transmission component 7 includes a transmission belt 9 and a plurality of transmission pulleys 8. The transmission belt is sleeved on the plurality of transmission pulleys 8. The transmission pulleys 8 are rotatably connected to the base 4. When the transmission pulleys 8 rotate, they can drive the transmission belt 9 to rotate.

[0084] The two belts on the adjacent base 4 form a conveying channel 1, which can clamp the tea leaves and convey them to the leaf collection bin 12 located at the rear end of the conveying channel 1.

[0085] In this embodiment, three transmission pulleys 8 are specifically set up to form a triangle, and are clamped and transported to a preset position by the transmission belts 9 on two adjacent bases 4.

[0086] like Figure 5 and 7 As shown: At least one of the transmission pulleys 8 located at the front end of the base 4 is provided with an eccentric wheel portion.

[0087] like Figure 2 and 6 As shown: The oscillating leaf assembly includes:

[0088] The oscillating blade component 2 includes a free end 6 and a rotating end 5. The rotating end 5 is disposed on the upper surface of the base 4, and the free end 6 extends away from the base 4 to the front of the base 4.

[0089] The free end 6 is provided with a leaf-pulling part 13. One end of the leaf-pulling part 13 is connected to the free end 6, and the other end is inclined downward in a direction away from the base 4. The width of the leaf-pulling part 13 gradually decreases along the inclined direction.

[0090] In this embodiment, the leaf-picking part 13 is designed such that, firstly, the gradually decreasing width in the vertical direction allows it to better reach into the gaps in the tea leaves, improving the efficiency of the oscillating leaf-picking component in combing the tea leaves, while the decreasing width in the horizontal direction allows the tea leaves to enter the conveying channel 1 more smoothly.

[0091] A rotating shaft is mounted on a base 4, and the free end 6 is sleeved outside the rotating shaft and can rotate relative to the rotating shaft.

[0092] Abutting member 10 is disposed between the free end 6 and the rotating end 5 on the swinging leaf member 2, and extends downward through the base 4 and abuts against the eccentric wheel portion on the transmission belt pulley 8.

[0093] The reset member 15 is disposed on the base 4 and abuts against the side of the transmission belt pulley 8 on the abutment member 10 away from the part of the eccentric wheel.

[0094] In this embodiment, the abutting member 10 abuts against the eccentric wheel portions on the two symmetrically arranged transmission pulleys 8 on the base 4. The two transmission pulleys 8 on the same base 44 rotate synchronously, allowing the free end 6 to swing. It can be understood that the reset member 15 is the eccentric wheel portion on another transmission pulley 8 on the same base 4 that is symmetrical to the eccentric wheel portion of the transmission pulley 8 that abuts against the abutting member 10. That is, the transmission pulley 8 that serves as the reset member 15 is also provided with an eccentric wheel portion.

[0095] In this embodiment, the abutment 10 is placed between two transmission pulleys 8 with eccentric wheel portions on the same base 4. Because the transmission components 7 are symmetrically arranged, this symmetry is both positional and overall shape-based. Specifically, the positions of the two eccentric wheel portions (the eccentric wheel portion on the transmission pulley 8 and the eccentric wheel portion on the reset member 15) are symmetrical, but the eccentric wheel portions deflect in the same direction. Therefore, when the two eccentric wheel portions rotate synchronously, taking the extreme position as an example, when one side of the abutment 10 abuts against the most protruding position (largest radius) of the eccentric wheel portion, the other side abuts against the least protruding position (smallest radius) of the other eccentric wheel portion, and vice versa. Thus, under the relative abutment of the rotational cooperation of the two, the abutment 10 can complete the reciprocating offset, i.e., swinging, and the transmission pulley 8 always abuts against the transmission belt, without the phenomenon of pulley separation. This is a part that can be achieved in the prior art and is not specifically limited in this application. For example, a connecting component to increase stability can be provided at the connection between the two.

[0096] Furthermore, in this embodiment, it should be further explained that, as mentioned above, the abutment 10 needs to abut against the eccentric wheel portion on the transmission pulley of the two symmetrically arranged transmission components 7, and these two transmission pulleys also need to abut against their respective corresponding transmission belts 9. Therefore, in order to ensure that the eccentric wheel portion can complete the above connection, in this embodiment, the abutment position of the eccentric wheel portion and the abutment 10 is set at a different height from the abutment position of the transmission pulley and the transmission belt 9. That is, in this embodiment, the abutment position of the eccentric wheel portion and the abutment 10 is set above the abutment position of the transmission pulley and the transmission belt 9.

[0097] like Figure 3 As shown: The leaf collection chamber 12 is located below the rear end of the transmission component 7, and there is a gap between the leaf collection chamber 12 and the rear end of the transmission component 7.

[0098] In this embodiment, the base 4 is inclined upward from its front end to its rear end relative to the bottom of the leaf collection chamber 12, and the front end of the base 4 is arranged at different lengths and staggered in its horizontal plane.

[0099] The base 4 is provided with a swing limiter to prevent the swing amplitude of the free end 6 on the swing blade 2.

[0100] In this embodiment, a swing limiting groove is provided between the free end 6 of the swing blade 2 and the position where the abutment 10 is provided. This swing limiting groove is a through groove, and the swing limiting member passes through the swing limiting groove and extends to the top of the swing blade 2 or is flush with the upper end surface of the swing blade 2. The swing limiting member is slidably connected to the swing limiting groove. Since the radius of the eccentric wheel is limited, the swing angle of the swing blade 2 can be initially limited, and then the swing angle of the swing blade 2 can be further limited to increase stability. In this embodiment, the specific swing limiting member is in the form of a screw and is connected to the base 4 by threads.

[0101] Example 2: The difference between this example and Example 1 lies in the arrangement between the first circular blade 3 and the second circular blade 11.

[0102] like Figure 9 As shown: In this embodiment, in the smallest unit group of the cyclical distribution, one first circular blade 3 and two second circular blades 11 are sequentially arranged. In the vertical direction, the first circular blade 3 sits on a plane between the planes where the two second circular blades 11 are located, and the first circular blade 3 and the two second circular blades 11 have overlapping parts. The connection between the smallest unit groups arranged cyclically in each periodic distribution also needs to meet the above conditions. That is to say, taking two groups as an example, from left to right, there is one first circular blade 3 (in the first group), two second circular blades 11 (in the first group), one first circular blade 3 (in the second group), and two second circular blades 11. The two circular blades in the first group and the first circular blade 3 in the second group have a vertical structure that requires the first circular blade 3 to sit on a plane between the planes of the two second circular blades 11, and the first circular blade 3 and the two second circular blades 11 have overlapping parts. Therefore, the blade arrangement in this embodiment can be summarized as follows: each first circular blade 3 has two second circular blades 11 on both sides, and they have overlapping parts. It can also be understood that each pair of second circular blades 11 has a first circular blade 3 on both sides, and there is an overlapping part between the second circular blade 11 and the first circular blade 3.

[0103] Example 3: The difference between this example and Example 1 lies in the arrangement between the first circular blade 3 and the second circular blade 11.

[0104] like Figure 10 As shown: In this embodiment, the smallest unit group of the periodic arrangement includes only one first circular blade 3 and one second circular blade 11. There is an overlap between the first circular blade 3 and the second circular blade 11 in the vertical direction. The overall blade arrangement can be understood as follows: each first circular blade 3 has a second circular blade 11 on both sides, and there is an overlap between the first circular blade 3 and the second circular blade 11 in the vertical direction. Alternatively, it can be understood as each second circular blade 11 has a first circular blade 3 on both sides, and there is an overlap between the first circular blade 3 and the second circular blade 11 in the vertical direction.

[0105] Example 4: Difference between this example and Example 1: Setting of reset component 15

[0106] like Figure 11 As shown: In this embodiment, an eccentric wheel (cam) is provided on a transmission pulley 8 located at the front end of the base 4, and the reset member is a spring;

[0107] The swing blade assembly is provided with a stop member 10, which is located between the free end 6 and the rotating end 5 of the swing blade assembly. The stop member 10 abuts against the eccentric wheel portion. The reset member abuts against the side of the stop member 10 away from the eccentric wheel portion. When the transmission pulley 8 rotates, the eccentric wheel portion moves with the stop member, thereby realizing the swing of the free end 6.

[0108] In this embodiment, the abutment 10 abuts only against one of the transmission pulleys 8 in one of the transmission components 7 on its base 4. When this transmission pulley 8 rotates, when its most protruding part pushes the abutment 10 away, there is no other transmission pulley 8 to push it back to its original position, so that the other parts of this transmission pulley 8 cannot abut against the abutment 10. The reset member is specifically set as a spring. The spring can push the abutment 10, which has been pushed away from the transmission pulley 8, towards the transmission pulley 8, so that the abutment 10 can always abut against the eccentric wheel part on this transmission pulley 8. The cooperation between the eccentric wheel part and the reset member, with the rotation of the eccentric wheel part, can complete the swing of the swing blade assembly.

[0109] Example 5: The difference between this example and Example 1 lies in the setting of the bud preservation board.

[0110] In this embodiment, the support frame is located below the cutting assembly (blade holder and circular blade), and the end of the bud-preserving plate below each base 4 extends away from the support frame to the front of the circular blade. This can be understood as the bud-preserving plate extending upwards and tilting towards the front of the overall device, extending to the front and above the circular blade, and located below the leaf-picking section 13.

[0111] Example 6: The difference between this example and Example 1 is the arrangement of the 14 swing limiters.

[0112] like Figure 12-13 As shown: In this embodiment, the swing limiting member 14 is disposed on the upper end surface of the base 4 and is located on both sides of the swing blade member 2, which is used to limit the swing angle of the swing blade member 2.

[0113] Example 7: The difference between this example and Example 1 lies in the arrangement of the cutting component.

[0114] like Figure 14-17 As shown: In this embodiment, the cutting assembly is located below the base. The cutting assembly includes a first blade holder 16 and a second blade holder 17. The first blade holder 16 abuts against the second blade holder 17. A plurality of first blade teeth 18 are evenly arranged on the first blade holder 16, and a plurality of second blade teeth 19 are evenly arranged on the second blade holder 17. The first blade teeth 18 and the second blade teeth 19 are spaced apart in the horizontal direction. The first blade holder 16 and the second blade holder 17 can slide relative to each other, so that the spaced first blade teeth 18 and the second blade teeth 19 overlap in the vertical direction or exchange positions in the horizontal direction to complete the cutting of the tea leaves.

[0115] In this embodiment, the first tool post and the second tool post are equivalent to the tool post in Embodiment 1.

[0116] Example 8: The difference between this example and Example 1 lies in the setting of the bud preservation board.

[0117] In this embodiment, the support frame is located below the blade holder. One end of the bud-preserving plate is rotatably connected to the support frame, and the other end extends upward at an angle to cover the front end of the cutting component directly below the base. It then continues to extend to the lower front position of the leaf-picking swinging component, that is, the bud-preserving plate extends onto the leaf-picking swinging component. When the leaf-picking swinging component swings, the bud-preserving plate swings with the leaf-picking swinging component.

[0118] Example 9: The difference between this example and Example 1 lies in the arrangement of the cutting component.

[0119] In this embodiment, the cutting assembly does not have a circular blade on the blade holder located directly below the base, thus ensuring that some of the young buds are well protected.

[0120] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model.
