Description

Technical Field

[0001] This utility model relates to the field of tea picking, specifically to a tea picking and collecting device. Background Technology

[0002] Tea, as a healthy beverage, has many beneficial components and effects on the human body, and is gradually becoming more and more popular.

[0003] During the tea picking process, the tender buds of each tea leaf are in uneven positions. Although manual tea picking can ensure the quality of tea to a certain extent, it has problems such as high labor intensity, harsh working environment, low picking efficiency, and large labor demand, which cannot meet the needs of large-scale tea picking. Therefore, mechanical tea picking will be gradually used in the tea industry.

[0004] Some existing tea-picking machines operate similarly to "scissors," where multiple cutting blades move and cut the tea stems through compression. For example, Chinese utility model patent CN215601984U discloses a handheld tea-picking device. Its technical solution includes a turntable 41 on the output shaft of a drive motor 4, a cutting blade 2 hinged to a transmission rod 21, and the transmission rod 21 and turntable 41 hinged together by a rotating shaft 22 parallel to the axis of the drive motor 4. The drive motor 4 drives the cutting blade 2 to reciprocate along the width of the support frame 1, thereby cutting the tea leaves.

[0005] The "scissors" cutting method has the following problems: When multiple cutting blades move to cut, the cut will gradually decrease because one end of the cutting blade has an angular structure. When the tea stem is hard or has a large diameter, the cutting blade is prone to slipping with the tea stem during the cutting process. This results in the tea stem and tea leaves not being cut quickly or the tea stem not being completely cut off, which cannot meet the requirements for picking tender tea buds. Summary of the Invention

[0006] The purpose of this utility model is to provide a tea picking and collecting device with a simple and compact structure. It enables the blades on a pair of cutting blades to move closer or further apart, allowing for rapid cutting and picking of tea stems. This avoids the phenomenon that thicker or harder tea stems may slide relative to the blades, resulting in the tea stems not being cut quickly or not being completely severed.

[0007] To achieve the above objectives, this tea leaf picking and collecting device includes:

[0008] The supporting cylinder has a through-passage inside for the tea leaves to pass through after picking;

[0009] The cutting component, located at the bottom of the support cylinder, includes:

[0010] A pair of cutting blades, each cutting blade has a cutting edge in the middle at the channel, and has a first end head and a second end head on both sides respectively;

[0011] The cutting edges in the pair of cutting blades are parallel to each other;

[0012] The first end heads in the pair of cutting blades are arranged symmetrically with the channel center and are rotationally connected to the supporting cylinder;

[0013] The second end heads in the pair of cutting blades are arranged symmetrically with the channel center and are movably connected to the supporting disc;

[0014] The supporting disc is driven by the driving component to rotate in both directions, so that the cutting edges of the pair of cutting blades are close to each other to close the channel, and are away from each other to open the channel.

[0015] In some examples of the utility model, the supporting disc is provided with external teeth on the periphery;

[0016] The driving component comprises a driving piece and a main gear;

[0017] The driving piece is installed on the supporting cylinder through a fixing seat, and the output end is fixedly connected with the main gear; the main gear is meshingly connected with the external teeth.

[0018] In some examples of the utility model, a pair of limiting grooves are arranged radially on the supporting disc;

[0019] The pair of cutting blades are arranged staggeredly, and the corresponding second end heads are slidably and rotationally arranged in the limiting grooves;

[0020] The supporting cylinder is provided with a positioning hole at the bottom end, and the first end head is rotationally arranged in the positioning hole.

[0021] In some examples of the utility model, a pair of limiting grooves are arranged radially on the supporting disc;

[0022] The second end head of the cutting blade is connected with one end of an elastic rod, and the other end of the elastic rod is slidably and rotationally arranged in the limiting groove;

[0023] The supporting cylinder is provided with a positioning hole at the bottom end, and the first end head is rotationally arranged in the positioning hole.

[0024] In some examples of the utility model, the supporting disc is provided with an annular boss structure in the middle and is rotationally connected to a fixing disc body through a bearing;

[0025] The supporting cylinder is provided with a sleeve penetrating from top to bottom in the middle, and the sleeve and the supporting disc form a channel for tea leaves;

[0026] The fixing disc body is detachably installed on the sleeve, and the upper end of the sleeve is connected with an output pipeline capable of generating negative pressure.

[0027] In some examples of the utility model, the support cylinder is provided with a strip-shaped groove; the main gear or the support disc can pass through the strip-shaped groove;

[0028] The driving part is provided with a protective shell outside.

[0029] In some examples of the utility model, the support cylinder moves up and down through the lifting part;

[0030] The support cylinder is provided with a sensor for identifying the position of tea leaves at this time, and the controller controls the driving part to act after receiving the signal of the sensor.

[0031] In some examples of the utility model, the output pipeline is provided with a negative pressure fan connected with the controller;

[0032] The controller controls the action of the negative pressure fan.

[0033] Compared with the prior art, the tea leaf picking and collecting device drives the middle blade of the cutting piece to rotate around the first end head through the forward and reverse rotation of the support disc, at this time, the blades on the pair of cutting pieces are parallel to each other and approach or move away from each other, the tea stem is quickly cut and picked, the phenomenon that the tea stem cannot be quickly cut off and the tea stem is not completely disconnected due to the sliding of the relatively thick and hard tea stem relative to the blade is avoided, and the picked tea leaves are collected.

[0034] Since the second end head of the cutting piece is movably located in the limiting groove of the support disc through the elastic rod, when the pair of cutting pieces contact and cut the tea stem, the elastic member can buffer a certain amount, realizing the elastic cutting of the tea stem and avoiding damage when the pair of cutting pieces collide;

[0035] Since the lifting part drives the support cylinder to move up and down, the cutting part at the lower end of the support cylinder can "single" pick tea leaves, effectively avoiding the problem that the "one-cut" picking mode causes the tea leaves and tea stems to be completely cut off due to the uneven length of the tea leaves, the damage of the tea leaves, and the mixing of new and old leaves.

[0056] As shown in Figures 1 to 6 The tea leaf picking and collecting device comprises:

[0057] The support cylinder 10 has an internal passage 11 that runs vertically and through which the picked tea leaves pass.

[0058] The cutting component is located at the bottom of the support cylinder 10 and comprises:

[0059] The pair of cutting blades 60 each has a cutting edge at the middle part thereof, which is located at the passage 11, and has a first end 61 and a second end 63 on both sides thereof.

[0060] The cutting edges of the pair of cutting blades 60 are parallel to each other.

[0061] The first ends 61 of the pair of cutting blades 60 are symmetrically arranged with respect to the center of the passage 11 and are rotationally connected to the support cylinder 10.

[0062] The second ends 63 of the pair of cutting blades 60 are symmetrically arranged with respect to the center of the passage 11 and are movably connected to the support disc 50.

[0063] The support disc 50 is driven by the driving component 30 to rotate in both directions, so that the cutting edges of the pair of cutting blades 60 are close to each other to close the passage 11 or away from each other to open the passage 11.

[0064] Specifically, the support cylinder 10 can be installed on a moving component or a lifting component to cooperate with the tea leaf picking and collecting system for picking and processing. The lower end of the support cylinder 10 is closed, the upper end is closed by a threadedly installed end cover 20, and the inside has a vertically running passage 11, which can facilitate the upward conveying and discharge of the picked tea leaves.

[0065] The cutting component is configured to cut and pick tea leaves, i.e. the middle part of each cutting piece 60 is located below the channel 11 and matches to act on the tea stem, the first end 61 and the second end 63 are located on both sides of the cutting edge of the cutting piece 60, the second end 63 can be extended by a support arm 62 away from the cutting edge by a certain length to facilitate assembly and movement of the cutting piece 60; the first end 61 and the second end 63 of the cutting piece 60 are arranged symmetrically with the center of the channel 11, i.e. the first end 61 of the cutting piece 60 is located on both sides of the channel 11, and the second end 63 is located on both sides of the channel 11; the cutting edges of the cutting piece 60 are parallel to each other;

[0066] The support disc 50 is connected with the driving component 30 and is configured to rotate forward and reverse at a certain angle, and under the action of the rotation of the support disc 50, the middle parts of the cutting pieces 60 are driven to move close to and away from each other, so that the continuous cutting action is completed;

[0067] As shown in the figure, Figure 7 When the tea leaf picking and collecting device is used in the initial stage, the cutting edges of the middle parts of the cutting pieces 60 are away from each other to open the channel 11;

[0068] The support cylinder 10 is moved so that the stem of the tea leaf is located below the channel 11, and whether the tea leaf is located in the channel 11 can be determined by a visual sensor;

[0069] The driving component 30 is started to drive the support disc 50 to rotate clockwise, because the first end 61 of the cutting piece 60 is rotationally connected to the support cylinder 10 and the second end 63 is movably connected to the support disc 50, the degree of freedom of the cutting piece 60 is limited, so that the cutting pieces 60 are rotated relative to each other under the action of the support disc 50, i.e. the cutting edges of the middle parts of the cutting pieces 60 are parallel to each other and close to each other to close the channel 11, complete the cutting and picking of the tea leaf, and the cut / picked tea leaf is discharged from the channel 11 for collection;

[0070] The support disc 50 is rotated counterclockwise again, the degree of freedom of the cutting piece 60 is limited, so that the cutting pieces 60 are rotated relative to each other under the action of the support disc 50, i.e. the cutting edges of the middle parts of the cutting pieces 60 are parallel to each other and away from each other to open the channel 11 for the next cutting action;

[0071] The tea leaf picking and collecting device rotates the cutting edges of the middle parts of the cutting pieces 60 around the first end 61 through the second end 63 under the action of the forward and reverse rotation of the support disc 50, so that the cutting edges of the cutting pieces 60 are close to or away from each other to quickly cut and pick the tea stem, avoid the phenomenon that the tea stem cannot be quickly cut off and the tea stem is not completely disconnected due to the sliding of the relatively thick and hard tea stem relative to the cutting edge, and collect the picked tea leaf.

[0072] In some examples of the present application,Figure 2 、 Figure 6 The support disc 50 is provided with external teeth on the side thereof;

[0073] The driving component 30 comprises a driving member 32 and a main gear 31;

[0074] The driving member 32 is installed on the support cylinder 10 through the fixing seat 15, and the output end is fixedly connected with the main gear 31;

[0075] The main gear 31 is in meshing connection with the external teeth;

[0076] Specifically, the fixing seat 15 can be tightly arranged on the side of the support cylinder 10 in an integral structure by welding, and a part thereof can be extended from the side of the support cylinder 10, and the fixing seat 15 can be reinforced by using a reinforcing rib to improve the stability of installation;

[0077] The driving member 32 can be a rudder, and left and right ear seats on the rudder can be installed on the fixing seat 15 through bolts, so that the rudder is closely adjacent to and connected with the support cylinder 10, and the negative influence caused by vibration during operation of the rudder is eliminated; the output end of the rudder is a transmission shaft, a connecting disc is installed at the end of the transmission shaft, and close connection with the main gear 31 is facilitated; eight connecting holes are arranged on the connecting disc, and the connecting disc is connected with the connecting holes on the main gear 31 through bolts in a corresponding manner, and under the close connection of the eight bolts, the rotation of the rudder is transmitted to the main gear 31 in real time and accurately; the main gear 31 is in meshing connection with the external teeth on the support disc 50 at the bottom of the support cylinder 10, so that the rotational potential energy generated by the rudder is transmitted to the support disc 50, and the rotation drives a pair of cutting blades 60 to move correspondingly, thereby realizing cutting of the tender bud part of tea leaves;

[0078] Alternatively, the output end of the rudder is connected with the support disc 50 through a crank rocker mechanism, that is, the rudder rotates circumferentially, the support disc 50 reciprocates at a certain angle through the crank rocker mechanism, and the picking action of the pair of cutting blades 60 on tea leaves is completed correspondingly; in this state, the continuous circumferential action of the rudder can be ensured, and the continuous reciprocating action of the support disc 50 is realized through the crank rocker mechanism, so that the efficiency is higher.

[0079] In some examples of the present application, as shown in Figure 4 、 Figure 6 A pair of radial limiting grooves 51 are arranged on the support disc 50;

[0080] The pair of cutting blades 60 are arranged in an up-down staggered manner, and the second end 63 slides and rotates in the limiting groove 51 correspondingly;

[0081] The bottom end of the support cylinder 10 is provided with a positioning hole 12, and the first end 61 rotates in the positioning hole 12;

[0082] Specifically, the pair of limiting grooves 51 are symmetrically arranged with the passage 11 as the center, that is, the second end head 63 is slid and appropriately rotated in the limiting groove 51, and when the support disc 50 is rotated, the second end head 63 is driven to rotate and slide in the limiting groove 51, so that the pair of cutting blades 60 are close to or away from each other;

[0083] The pair of cutting blades 60 can be in the same plane, and preferably, the pair of cutting blades 60 are slightly staggered in height, so as to avoid collision of the middle blades when they are close to each other;

[0084] The positioning hole 12 at the bottom end of the support cylinder 10 is used for placing the first end head 61, that is, the first end head 61 is installed on the support cylinder 10 and the relative position does not change, and the second end head 63 can be a cylindrical head and is assembled with the positioning hole 12 through a bearing and a circlip.

[0085] In some examples of the utility model, a pair of limiting grooves 51 are arranged on the support disc 50 in a radial direction;

[0086] The second end head 63 of the cutting blade 60 is connected with one end of an elastic rod, and the other end of the elastic rod is slid and rotated in the limiting groove 51;

[0087] The bottom end of the support cylinder 10 is provided with the positioning hole 12, and the first end head 61 is rotated in the positioning hole 12;

[0088] Specifically, the elastic rod is configured to appropriately buffer the cutting blade 60, so as to avoid damage of the cutting blade 60 when colliding; when the support disc 50 is rotated, the second end head 63 is driven to rotate around the corresponding first end head 61 through the elastic member, and when the pair of cutting blades 60 contact and cut the tea stems, the elastic member can buffer a certain amount, so as to realize elastic cutting of the tea stems.

[0089] In some examples of the utility model, as shown in Figure 3 The middle part of the support disc 50 is an annular boss structure and is rotationally connected to the fixed disc body 70 through a bearing;

[0090] The middle part of the support cylinder 10 is provided with a sleeve 13 which penetrates up and down, and the sleeve 13 and the support disc 50 form a passage 11 through which tea passes;

[0091] The fixed disc body 70 is detachably mounted on the sleeve 13, and the upper end of the sleeve 13 is connected with the output pipeline 40 which can generate negative pressure;

[0092] Specifically, the support disc 50 and the fixed disc body 70 can form a 2mm interval, which is used for relieving up and down vibration generated when the support disc 50 is rotated, so as to reduce resistance in the movement process and guarantee precise transmission of the driving part 30 and the support disc 50;

[0093] The fixed disc body 70 can be disassembled and installed on the sleeve 13 through positioning pins to facilitate disassembly of the cutting part;

[0094] The sleeve 13 and the middle part of the support disc 50 are formed with a channel 11, which facilitates the conveying of tea leaves, that is, the output pipeline 40 is provided with a negative pressure part such as a negative pressure fan, and in this state, the conveying pipeline can convey and collect the picked tea leaves.

[0095] Preferably, the negative pressure fan is connected with a controller, and the controller controls the action of the negative pressure fan; the action includes starting, stopping and negative pressure power adjustment of the negative pressure fan to meet different use requirements.

[0096] In some examples of the present application, as shown in Figure 2 、 Figure 4 The support cylinder 10 is provided with a strip-shaped groove 14;

[0097] The main gear 31 or the support disc 50 can pass through the strip-shaped groove 14;

[0098] The driving part 30 is provided with a protective shell on the outside;

[0099] Specifically, since the steering wheel is arranged outside the support cylinder 10, the strip-shaped groove 14 can ensure that the main gear 31 and the support disc 50 are engaged with each other;

[0100] In the working condition, sand, branches, leaves and the like can affect the engagement of the main gear 31 and the support disc 50, and therefore the protective shell is arranged on the outside of the driving part 30.

[0101] In some examples of the present application, the support cylinder 10 moves up and down through the lifting part;

[0102] At this time, the support cylinder 10 is provided with a sensor for identifying the position of tea leaves, and the controller controls the action of the driving part 30 after receiving the signal of the sensor;

[0103] Specifically, the support cylinder 10 is installed on the output end of the lifting part, and the lifting part can be located on a moving trolley, that is, the moving trolley moves along the direction of the tea ridge, the lifting part drives the support cylinder 10 to move downward, and the position of the tea leaves is positioned through the sensor; it is explained that the sensor can be a visual sensor, a distance sensor or the like; when the tea leaves are located in the channel 11, the controller receives the signal of the sensor and controls the driving part 30 to start, drives the support disc 50 and a pair of cutting blades 60 to act, completes the picking of the tea leaves, and at the same time, the controller controls the negative pressure of the output pipeline 40 to collect the picked tea leaves;

[0104] The present example drives the supporting cylinder 10 to move up and down through the lifting component, so that the cutting component at the lower end of the supporting cylinder 10 can "single" pick tea, effectively avoiding the problem that the "one-cut" picking mode causes tea and tea stems to be cut off due to uneven length of tea, tea damage, and new and old leaves mixed.

[0105] The tea picking and collecting device exemplary embodiment proposed by the present application is described in detail above with reference to the preferred embodiments, however, those skilled in the art can understand that various modifications and improvements can be made to the above specific embodiments without departing from the concept of the present application, and various technical features and structures proposed by the present application can be combined without exceeding the protection scope of the present application, and the protection scope of the present application is determined by the appended claims.
