Description

Technical Field

[0001] The present invention relates to the field of tea leaf picking, and particularly to a partition cutting and harvesting and young bud protection device for a new type of tea picking machine. Background Art

[0002] As the country with the largest population of tea drinkers in the world, the tea industry in China has extremely strict requirements for the uniformity of raw materials - from the length standard of bud leaves to the morphological norms of bud leaves, which constitute a rare quality control threshold for tea raw materials in the world. Although traditional manual picking can achieve basic grading, the differences in the techniques of different individuals still result in uneven sizes of the picked bud leaves. Coupled with the fact that labor costs are rising year by year, the mode of relying on manual picking to precisely control the length of bud leaves is becoming increasingly unsustainable in large-scale production. The standardization dilemma of tea leaf picking is forcing the transformation of tea leaf picking towards mechanization.

[0003] With the development of mechanized tea leaf picking, reciprocating tea picking machines already exist in the market. For example, the tea picking machine disclosed in CN108207313A includes a vehicle body with a traveling mechanism arranged at the bottom, a column is arranged on the vehicle body, a scissor unit is arranged on a scissor support, the scissor unit is integrally arranged in a curved arc shape that fits the curved surface shape of the tea tree crown A, the scissor support is connected to the column, a pneumatic purging pipe and a tea collection bag are arranged on the scissor support, the air flow discharge direction of the pneumatic purging pipe points to the position of the bag mouth of the tea collection bag, the scissor unit is located between the air outlet of the pneumatic purging pipe and the bag mouth of the tea collection bag, and the tea leaves cut by the scissor unit are immediately blown towards the position of the bag mouth of the tea collection bag by the air flow discharged from the pneumatic purging pipe. In this way, during the process of the tea picking machine walking and cutting at the same time, the tea leaves are timely collected into the tea collection bag. After the tea collection bag collects an appropriate amount of tea leaves, the tea collection bag can be replaced or the tea leaves in the bag can be poured 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 fan impeller, the lower output shaft of the DC motor is fixed to the central shaft of the crankshaft disk, the two eccentric shaft pins of the crankshaft disk are respectively movably connected to the large head ends of the upper and lower connecting rods, and the small head ends of the upper and lower connecting rods are respectively movably connected to the upper and lower blades. Alternatively, the lower output shaft of the DC motor is set as an external gear shaft, which meshes with the internal gear of an internal and external diameter gear, and the external gear of the internal and external diameter gear meshes with the outer diameter edge gear of the crankshaft disk.

[0005] The above technical solutions cut everything that enters the shearing range and send it into the leaf collection bin without discrimination. The tea leaves trimmed by it include a mixture of raw materials such as bud leaves, single leaves, broken pieces, old leaves, and old tea stalks. The cut broken pieces, old leaves, old tea stalks and other materials are not suitable for use and need to be selected later, which increases the tea processing cost and causes waste of energy at the same time.

[0006] Therefore, it is necessary to design a partitioned cutting and harvesting and young bud protection device for a new type of tea picking machine to assist in efficiently harvesting suitable tea buds and leaves during machine picking, protecting young buds that are not suitable for picking, and assisting the tea buds and leaves cut and harvested by the machine to better enter the leaf collection bag along the feeding port, automatically separating cut fragments, broken stalks, etc., improving the evenness of tea leaf picking, and being able to solve the problem of machine cutting damaging young buds existing in the above-mentioned existing equipment. Summary of the Invention

[0007] The purpose of the present invention is to provide a partitioned cutting and harvesting and young bud protection device for a new type of tea picking machine, which can assist in better entering the transportation channel of the tea picking machine during tea picking, improving the evenness of tea bud and leaf picking and the protection rate of young buds, so as to solve the existing technical defects and unachievable technical requirements.

[0008] To achieve the above purpose, the present invention provides the following technical solution: A partitioned cutting and harvesting and young bud protection device for a new type of tea picking machine, comprising:

[0009] A number of bases, with a conveying channel formed between adjacent bases;

[0010] A swinging leaf component, which is arranged at the front end of the base, and the swinging leaf component is rotationally connected to the base;

[0011] A cutting component, which is arranged below a number of bases and is connected to the bases;

[0012] A young bud protection component, which is connected to the base and is arranged above or below the cutting component. The part of the young bud protection component located below the base extends forward to the front of the cutting component;

[0013] When the swinging leaf component swings, it can comb the tea leaves to both sides to assist the tea leaves to enter the conveying channel, and the young bud protection component blocks some young buds to prevent the young buds from being cut by the cutting component.

[0014] It should be further explained in this application that in the above content, a transmission component is arranged below the base. The transmission component adopts the form of a conveyor belt. The conveying channel is specifically formed between adjacent two transmission components. There is a feeding port formed by two transmission components at the front end of the conveying channel, and there is a discharging port formed between two transmission components at the rear end of the conveying channel. The young bud protection component and the cutting component are located below the transmission component. In addition, regarding the position of the cutting component in this application, the cutting component is arranged below a number of bases, or only arranged below the feeding port, that is, there is no cutting component arranged below the base or the circular blade and cutter teeth described below are not arranged.

[0015] Preferably, the young bud protection component includes:

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

[0017] A bud protection plate, which is spacedly disposed on the support frame and is only disposed below each base. One end of the bud protection plate is connected to the support frame, and the other end extends away from the support frame, at least extending to the front of the cutting assembly, capable of covering the front end of the cutting assembly to prevent the young buds located below the base from being cut by the cutting assembly.

[0018] In this application, the content that the bud protection plate is only disposed below the base can be understood as that the whole bud protection plate is located below the base. It can extend in the length direction of the base, or in the vertical direction, or be an inclined extension after combining the above two directions, but the bud protection plate cannot extend in the width direction of the base, that is, the width of the bud protection plate cannot exceed the width of the conveying assembly, and it does not block the tea leaves entering the conveying channel or below the conveying channel.

[0019] Preferably, the cutting assembly includes a tool rest, a first circular blade and a second circular blade. The tool rest is connected to the base and is located below several bases of the base. The first circular blade and the second circular blade are periodically distributed along the length direction of the tool rest on the tool rest, and the first circular blade and the second circular blade can rotate on the tool rest;

[0020] When the first circular blade and the second circular blade rotate, they can cut the tea leaves entering the conveying channel.

[0021] In this application, the structure of installing the blade on the tool rest in the above content belongs to a common technology in the prior art. For example, the blade can be installed on a rotating shaft, and the tool rest is provided with a hole for installing the rotating shaft. The rotating shaft passes through this hole and is installed on the tool rest. The rotating shaft can rotate on the tool rest, and the rotating shaft is connected to the output end of the driving motor. By driving the rotating shaft to rotate through the driving motor, the blade rotates and other methods are realized. This application does not specifically limit the driving of the blade and the connection method between the blade and the tool rest.

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

[0023] In this application, the structures of the first circular blade and the second circular blade can be understood as follows: Firstly, they partially overlap in the vertical direction. It can be understood that in the vertical direction, the first circular blade and the second circular blade are located on different layers respectively, and there is partial overlap between the cutting edges or contours. In terms of quantity, the two types of blades can be in a one-to-one correspondence, or a one-to-many relationship, or a many-to-many relationship. When the quantity is one-to-many or many-to-many, the blades with a larger quantity are arranged at intervals in the vertical direction, and the other type of blade is located within the intervals of the blades arranged at intervals in the vertical direction and partially overlaps. For the contours being tangent, it can be understood that the two types of blades are located within the same layer, and the circles where their cutting edges are located are tangent to each other. Additionally, the "layer" mentioned above can be understood as the plane where the blade is located. It should be additionally noted that for the content overlapping in the vertical direction, the two types of blades mentioned above are "periodically" distributed on the tool holder. This can be understood as the combination of the two types of blades described in this paragraph is a periodically recurring group. Although it is periodically distributed in the form of a group, the groups should also conform to the distribution explanation within the periodically recurring group of the two types of blades in this paragraph. For example, a periodically recurring group consists of one first circular blade and two second circular blades. In the vertical direction of the group, the overlapping parts from top to bottom are the second circular blade, the first circular blade, and the second circular blade in sequence. Then, for a first circular blade in the group adjacent to the above group, it should also have an overlapping part between the two second circular blades in the above group. That is, the arrangement of the blades within the periodically recurring group is one first circular blade and two second circular blades in the horizontal direction. The connection relationship between the two groups is that the sides of the two second circular blades distributed at intervals in the vertical direction overlap with the first circular blade within the same group, and the other sides also overlap 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 tool holder and a second tool holder. The first tool holder abuts against the second tool holder. A plurality of first cutter teeth are evenly arranged on the first tool holder, and a plurality of second cutter teeth are evenly arranged on the second tool holder. The first cutter teeth and the second cutter teeth are distributed at intervals in the horizontal direction. The first tool holder and the second tool holder can slide relative to each other, so that the spaced first cutter teeth and second cutter teeth overlap in the vertical direction or exchange positions in the horizontal direction to complete the shearing of the tea leaves.

[0025] Preferably, two transmission assemblies are symmetrically arranged on the lower end surface of each base, and a swing leaf assembly is arranged on the upper end surface of each base. A feeding channel is formed between the transmission assemblies on adjacent bases.

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

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

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

[0029] In this application, it should be further explained that the above-mentioned eccentric wheel part is a kind of cam structure. In this application, the eccentric wheel part is just one of the ways. It can be understood that the swing of the swing leaf component in this application is realized through the cam structure.

[0030] Preferably, the swing leaf component includes:

[0031] A swing leaf member, which includes a free end and a rotating end. The rotating end is arranged on the upper end surface of the base, and the free end extends away from the base to the front of the base;

[0032] A rotating shaft, which is arranged on the base. The free end is sleeved outside the rotating shaft and can rotate relative to the rotating shaft;

[0033] An abutting member, which is arranged between the free end and the rotating end of the swing leaf member. It extends downward through the base and abuts against the eccentric wheel part on the transmission belt pulley;

[0034] A reset member, which is arranged on the base and abuts against the side of the abutting member away from the transmission belt pulley provided with the eccentric wheel part.

[0035] In this application, the above content can be understood as that the reset member and the eccentric wheel part are respectively located on both sides of the abutting member. The reset member can be in the form of a reset member or a cam structure adapted to the eccentric wheel part. In addition, it is mentioned in the above content that the lower end of the abutting member passes through the base. Therefore, it should be supplemented that in this application, it is obvious that the free end is swung by moving the abutting member. Therefore, the holes or grooves provided on the base for the abutting member to penetrate can provide enough space for the movement of the abutting member.

[0036] Preferably, the support frame is located below the cutting assembly. The bud protection plate extends obliquely upward away from the support frame, covering the front part of the cutting assembly directly below the base and extending to the lower part of the swing leaf member.

[0037] Alternatively, one end of the bud protection plate is rotatably connected to the support frame, and the other end extends obliquely upward. After covering the front part of the cutting assembly directly below the base, it is connected to the front end of the swinging leaf swinging member and swings with the swinging leaf swinging member.

[0038] Preferably, the leaf collecting bin is located below the rear end of the transmission assembly, and there is a spaced space between the leaf collecting bin and the rear end of the transmission assembly.

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

[0040] Preferably, a swinging limiting member is provided on the base to prevent the swinging amplitude of the free end of the swinging leaf member.

[0041] Compared with the prior art, the beneficial effects of the present invention are:

[0042] 1. In this application, through the swinging leaf assembly, the tea leaves are combed and dialed to both sides, which can assist the tea leaves to better enter the conveying channel along the feeding port in different areas during tea leaf picking, improving the efficiency of tea leaf picking and sorting. Moreover, with the assistance of the swinging leaf assembly, when the device moves forward during use, it can prevent the tea leaves from being pushed down and bent, making it easier for the tea leaves to be clamped by the feeding assembly, thereby improving the harvesting efficiency and avoiding the occurrence of missed harvesting.

[0043] 2. In this application, through the young bud protection assembly, the suitable bud leaves are cut and harvested, while avoiding damage to the young buds that cannot be picked on the tea tree, thereby shortening the secondary picking cycle and reducing the impact on tea leaf yield.

Detailed implementation manners

[0062] Next, the appended drawings in the embodiments of the present invention will be combined Figure 1-17, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0063] In the description of the present invention, it should be understood that the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0064] Please refer to Figure 1-17 , the embodiments of the present invention:

[0065] Embodiment 1:

[0066] As Figure 1-2 shown: It includes:

[0067] Several bases 4, and a conveying channel 1 is formed between adjacent bases 4;

[0068] A swinging blade assembly, which is arranged at the front end of the base 4 and is rotationally connected to the base 4;

[0069] A cutting assembly, which is arranged below several bases 4 and is connected to the base 4;

[0070] A young bud protection assembly, which is connected to the base 4 and is arranged above or below the cutting assembly. The part of the young bud protection assembly located below the base 4 extends forward to the front of the cutting assembly;

[0071] When the swinging blade assembly swings, it can comb the tea leaves to both sides to assist the tea leaves to enter the conveying channel 1, and the young bud protection assembly blocks some young buds to prevent the young buds from being cut by the cutting assembly.

[0072] In this embodiment, through the setting of the swinging blade assembly, during tea picking, the tea leaves can be actively combed to both sides, so that the tea leaves can smoothly enter the conveying channel 1 for centralized picking, improving the efficiency of tea leaf picking and sorting, and avoiding the phenomenon that because the tea leaves are dense, the tea leaves are pushed down and bent, making it difficult to be clamped by the feeding unit, thus affecting the harvesting and picking rate.

[0073] And through the young bud protection assembly, the suitable bud leaves are cut and harvested, while avoiding damage to the young buds that cannot be picked on the tea tree, thereby shortening the secondary picking cycle and reducing the impact on the tea leaf yield.

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

[0075] When the first circular blade 3 and the second circular blade rotate, they can cut the tea leaves entering the conveying channel 1.

[0076] As Figure 8 shown: The first circular blade 3 and the second circular blade 11 partially overlap in the vertical direction or are tangential to each other in contour in the horizontal direction.

[0077] In this embodiment, the arrangement of the first circular blade 3 and the second circular blade 11 adopts the contour tangency of the two blades in the horizontal direction, and the order is in the order of the first circular blade 3 and the second circular blade 11. The connection relationship between groups (the smallest cycle unit) in the periodic cycle distribution is also tangency, 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 "periodic cycle group". In this embodiment, the arrangement of the two circular blades can also be understood as that each side of the first circular blade 3 is tangent to the second circular blade 11 on both sides, and each side of the second circular blade 11 is tangent to the first circular blade 3 on both sides. And the tangent points of the two circular blades are located directly below the conveying channel 1.

[0078] The young bud protection assembly includes:

[0079] A support frame, which is connected to the base 4 and is arranged above or below the tool rest;

[0080] A bud protection plate 20, which is spaced on the support frame and is only arranged below each base 4. One end of the bud protection plate 20 is connected to the support frame, and the other end extends away from the support frame, at least extending to the front of the cutting assembly to prevent the young buds located below the base 4 from being cut by the cutting assembly.

[0081] In this embodiment, the support frame is arranged above the tool rest. After the front end of the bud protection plate 20 extends to the front of the blade, it bends downward to a position lower than the lower end face of the blade, and then extends toward the support frame to the lower part of the blade, covering the blade directly below the base 4 in a semi-surrounding manner to prevent some young buds from being damaged by the cutting assembly without affecting the entry of suitable tea leaves into the conveying channel 1.

[0082] As Figure 1-4As shown: On the lower end surface of each base 4, two transmission components 7 are symmetrically arranged. On the upper end surface of each base 4, a swinging flap component is arranged. A feeding channel is formed between the transmission components 7 on adjacent bases 4.

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

[0084] A conveying channel 1 is formed between the two belts on adjacent bases 4, which can clamp the tea leaves and convey the tea leaves to the leaf collecting bin 12 located at the rear end of the conveying channel 1.

[0085] In this embodiment, specifically, three transmission belt pulleys 8 are arranged to form a triangle, and the tea leaves are clamped and conveyed to a preset position through the transmission belts 9 on two adjacent bases 4.

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

[0087] As Figure 2 and 6 shown: The swinging flap component includes:

[0088] A swinging flap member 2, which includes a free end 6 and a rotating end 5. The rotating end 5 is arranged on the upper end surface of the base 4, and the free end 6 extends forward away from the base 4 to the front of the base 4;

[0089] A flap part 13 is arranged on the free end 6. One end of the flap part 13 is connected to the free end 6, and the other end inclines downward away from the base 4, and the width of the flap part 13 gradually becomes smaller along the inclined direction.

[0090] In this embodiment, the setting of the flap part 13, firstly, the gradually decreasing width in the vertical direction can better extend into the gaps between the tea leaves, improving the combing efficiency of the swinging flap component for the tea leaves. And the decreasing width in the horizontal direction enables the tea leaves to enter the conveying channel 1 more smoothly.

[0091] A rotating shaft, which is arranged on the base 4. The free end 6 is sleeved outside the rotating shaft and can rotate relative to the rotating shaft;

[0092] A abutting member 10, which is arranged between the free end 6 and the rotating end 5 of the swinging flap member 2, and extends downward through the base 4 and abuts against the eccentric wheel part on the transmission belt pulley 8;

[0093] A reset member 15 is disposed on the base 4 and abuts against a side of the abutting member 10 away from the transmission pulley 8 provided with the eccentric wheel portion.

[0094] In this embodiment, the abutting member 10 abuts against the eccentric wheel portions on two symmetrically arranged transmission pulleys 8 on the base 4 where it is located. The two transmission pulleys 8 on the same base 4 rotate synchronously, enabling the free end 6 to swing. That is to say, the reset member 15 is the eccentric wheel portion on another transmission pulley 8 that is symmetric to the transmission pulley 8 corresponding to the eccentric wheel portion abutting against the abutting member 10 on the same base 4. That is, the transmission pulley 8 serving as the reset member 15 is also provided with an eccentric wheel portion.

[0095] In this embodiment, the abutting member 10 is abutted between two transmission pulleys 8 provided with eccentric wheel portions. On the same base 4, since the transmission assembly 7 is symmetrically arranged, this symmetrical arrangement is in terms of position and overall shape. 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 symmetric, but the directions of the eccentricities of the eccentric wheel portions are the same. Therefore, when the two eccentric wheel portions rotate synchronously, taking the extreme positions as an example, when one side of the abutting member 10 abuts against the most protruding position (the largest radius) of the eccentric wheel portion, the other side abuts against the least protruding position (the smallest radius) of the other eccentric wheel portion, and vice versa. Therefore, under the relative abutment of the rotational cooperation of the two, the abutting member 10 can complete reciprocating offset, that is, swing, and the transmission pulley 8 always abuts against the transmission belt, and the phenomenon of pulley separation will not occur. This is the part that can be achieved in the prior art and is not specifically limited in this application. For example, connection components for increasing stability are provided at their connection points.

[0096] In addition, in this embodiment, it needs to be further explained that in the above text, the abutting member 10 needs to abut against the eccentric wheel portions on the transmission pulleys in two symmetrically arranged transmission assemblies 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 portions can complete the above connections, in this embodiment, the abutting positions of the eccentric wheel portions and the abutting member 10 are set at different heights from the abutting positions of the transmission pulleys and the transmission belt 9. That is, in this embodiment, the abutting positions of the eccentric wheel portions and the abutting member 10 are set above the abutting positions of the transmission pulleys and the transmission belt 9.

[0097] As Figure 3 shown: The leaf collecting bin 12 is located below the rear end of the transmission assembly 7, and there is an interval space between the leaf collecting bin 12 and the rear end of the transmission assembly 7.

[0098] In this embodiment, the base 4 is inclined upward relative to the bottom of the leaf collecting bin 12 in the extending direction from its front end to its rear end, and the front ends of the base 4 are arranged at uneven intervals in its horizontal plane.

[0099] A swing limiting member is arranged on the base 4 to prevent the swing amplitude of the free end 6 of the swing blade member 2.

[0100] In this embodiment, a swing limiting groove is arranged between the free end 6 of the swing blade member 2 and the position where the abutting member 10 is arranged. This swing limiting groove is a through groove, and the swing limiting member passes through the swing limiting groove and extends above the swing blade member 2 or is flush with the upper end surface of the swing blade member 2. The swing limiting member is slidably connected with the swing limiting groove. After the radius of the eccentric wheel part is limited and the swing angle of the swing blade member 2 can be preliminarily limited, the swing angle of the swing blade member 2 is further limited to increase stability. In this embodiment, specifically, the swing limiting member adopts the form of a screw and is connected to the base 4 through a thread.

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

[0102] As Figure 9 shown: In this embodiment, in the smallest unit group that circulates in the periodic distribution, one first circular blade 3 and two second circular blades 11 are arranged in sequence. In the vertical direction, the plane where the first circular blade 3 is located is between the planes where the two second circular blades 11 are located, and the first circular blade 3 overlaps with both of the two second circular blades 11; and the connection between the smallest unit groups arranged in a cyclic manner 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 (in the second group). And the structure of the two circular blades in the first group and the first circular blade 3 in the second group in the vertical direction also needs to meet the condition that "the plane where the first circular blade 3 is located is between the planes where the two second circular blades 11 are located, and the first circular blade 3 overlaps with both of the two second circular blades 11". Therefore, the blade arrangement method in this embodiment can be summarized as that two second circular blades 11 are arranged on both sides of each first circular blade 3 and there is an overlapping part, or it can also be understood that one first circular blade 3 is arranged on both sides of every two second circular blades 11, and there is an overlapping part between the second circular blade 11 and the first circular blade 3.

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

[0104] AsFigure 10 As shown: In this embodiment, the minimum unit group of the periodic arrangement includes only one first circular blade 3 and one second circular blade 11, and there is an overlapping part between the first circular blade 3 and the second circular blade 11 in the vertical direction; the overall blade arrangement can be understood as, each first circular blade 3 is provided with a second circular blade 11 on both sides, and there is an overlapping part between the first circular blade 3 and the second circular blade 11 in the vertical direction, and it can also be understood as, each second circular blade 11 is provided with a first circular blade 3 on both sides, and there is an overlapping part between the first circular blade 3 and the second circular blade 11 in the vertical direction.

[0105] Example 4: The difference between this example and example 1 is the setting of the reset member 15

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

[0107] The swinging blade assembly is provided with a supporting member 10, which is located between the free end 6 and the rotating end 5 of the swinging blade assembly, and the supporting member 10 is in abutment with the eccentric wheel part. The reset member is in abutment with the side of the supporting member 10 away from the eccentric wheel part. When the transmission pulley 8 rotates, the eccentric wheel part can move with the supporting member to realize the swing of the free end 6.

[0108] In this embodiment, the abutment 10 only abuts against one of the transmission pulleys 8 in one of the transmission assemblies 7 on the base 4 where it is located. When this transmission pulley 8 rotates, when its most protruding part pushes the abutment 10 to a distance, 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 complete the abutment with the abutment 10. The setting of the reset member, specifically, the reset member is set as a spring. The spring can push the abutment 10 that is away from the transmission pulley 8 after being abutted to approach this transmission pulley 8, so that the abutment 10 can always abut against the eccentric wheel part on this transmission pulley 8. The cooperation of the eccentric wheel part and the reset member can complete the swinging of the swinging blade assembly as the eccentric wheel part rotates.

[0109] Example 5: The difference between this example and example 1 is the setting of the sprout protection board

[0110] In this embodiment, the support frame is arranged below the cutting assembly (the knife holder and the circular blade), and the end of the bud-protecting plate below each base 4 away from the support frame extends to the front of the circular blade. It can be understood that the bud-protecting plate extends upward and tilted toward the front of the entire device, extends to the front and upper part of the circular blade, and is located below the leaf-picking part 13.

[0111] Example 6: The difference between this example and Example 1 lies in the setting of the swing limiting member 14.

[0112] As Figure 12-13 shown: In this example, the swing limiting member 14 is arranged on the upper end surface of the base 4 and is located on both sides of the swing blade member 2 respectively, for limiting the swing angle of the swing blade member 2.

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

[0114] As Figure 14-17 shown: In this example, the cutting assembly is located below the base. The cutting assembly includes a first tool rest 16 and a second tool rest 17. The first tool rest 16 abuts against the second tool rest 17. A number of first cutter teeth 18 are evenly arranged on the first tool rest 16, and a number of second cutter teeth 19 are evenly arranged on the second tool rest 17. The first cutter teeth 18 and the second cutter teeth 19 are distributed at intervals in the horizontal direction. The first tool rest 16 and the second tool rest 17 can slide relative to each other, so that the spaced first cutter teeth 18 and second cutter teeth 19 overlap in the vertical direction or exchange positions in the horizontal direction to complete the shearing of the tea leaves.

[0115] In this example, the first tool rest and the second tool rest are equivalent to the tool rest in Example 1.

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

[0117] In this example, the support frame is arranged below the tool rest. One end of the bud protection plate is rotatably connected to the support frame, and the other end extends obliquely upward to be able to cover the front end of the cutting assembly directly below the base and then continues to extend to a position in front of the lower end of the leaf swinging member, that is, the bud protection plate extends to the leaf swinging member. When the leaf swinging member swings, the bud protection plate swings with the leaf swinging member.

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

[0119] In this example, in the cutting assembly, circular blades are not arranged on the tool rest directly below the base, so that better protection of some young buds can be ensured.
