[0023] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Figure 1-Figure 7 .

[0024] The tea leaf trimmer with a telescopic adjustment mechanism comprises a gripping portion 1 arranged on one side, through which an operator holds the tea leaf trimmer, and control components such as a switch assembly are arranged on the gripping portion 1, so that when in use, the operator controls and holds the entire trimmer through the gripping portion 1.

[0025] The gripping part 1 comprises a frame 101, one end of which is fixedly connected to the gripping part 1, and the other end of which extends to one side of the gripping part 1 to form a narrow and long frame. A trimming tool 3 is arranged on the frame 101, and the trimming tool 3 is arranged on one side of the frame 101 in the direction of travel when the trimmer is in operation. Figure 1shown.

[0026] The pruning tool 3 is connected to the driving unit 2 in a transmission manner. The pruning tool 2 is a reciprocating shearing tool, which is a conventional setting in the field and will not be elaborated on here. The driving unit 2 drives the pruning tool 2 to reciprocate and shear, thereby achieving pruning of tea tree branches and leaves.

[0027] The front end of the frame 101 is provided with a pruning tool 3, and the bottom is provided with a support plate 102 for supporting the upper surface of the pruned tea tree. The support plate 102 is laterally provided with a plurality of groups of lateral telescopically adjustable walking units 4, such as Figure 1 As shown, the walking unit 4 includes a first walking wheel 401 and a second walking wheel 402, and the first walking wheel 401 and the second walking wheel 402 are connected by a walking belt 403; the frame 101 is provided with a driving shaft 103 for installing the first walking wheel 401 and a driven shaft 104 for installing the second walking wheel 402.

[0028] The two ends of the driving shaft 103 and the driven shaft 104 are rotatably arranged on both sides of the frame 101, and the inner hole of the first walking wheel 401 is slidably arranged on the driving shaft 103. Preferably, the cooperation adopts the cooperation of non-circular hole and non-circular shaft, so that the driving shaft 103 drives the first walking wheel 401 to rotate, and the first walking wheel 401 can also slide laterally relative to the driving shaft 103; specifically, the driving shaft 103 and the first walking wheel 401 cooperate with each other. The section adopts a non-circular shaft, such as a hexagonal shaft, and the inner hole of the first walking wheel 401 is provided with a non-circular hole, such as a hexagonal hole, so as to achieve the above effect; the cooperation between the second walking wheel 402 and the driven shaft 104 is the same as the cooperation between the first walking wheel 401 and the driving shaft 103, and no further details are given; through the above cooperation, the walking unit 4 as a whole can realize sliding adjustment relative to the driving shaft 103 and the driven shaft 104.

[0029] The driving shaft 103 is in transmission connection with the driving unit 2, so that the driving unit 2 synchronously drives the driving shaft 103 to rotate when working, thereby realizing the walking of the walking unit 4; the supporting plate 102 is provided with a notch 105 which matches the walking unit 4, and the lower bottom surface of the walking unit 4 is placed in the notch 105, and the surface of the walking belt 403 at the lower bottom surface of the walking unit 4 is lower than the lower end surface of the supporting plate 102, so that when the trimmer is trimming, the walking belt 403 is in direct contact with the upper surface of the pruned tea tree, so as to realize the action of the walking unit 4 driving the trimmer to crawl on the tea tree.

[0030] The two sides of the slot 105 are wider than the two sides of the walking unit 4, providing a certain space for the lateral movement of the walking unit 4. After the lateral movement of the walking unit 4 is adjusted, the distance between adjacent walking units 4 can be adjusted. When the overall width of the tea tree is wider, the spacing between adjacent walking units 4 can be increased to make the entire trimmer walk more stably on the upper surface of the tea tree; in addition, multiple walking units 4 can also be added to achieve the stability of the trimmer's walking. In this embodiment, taking the setting of 4 groups of walking units 4 as an example, the specific adaptive adjustment can be made according to the overall length and mass of the trimmer.

[0031] like Figure 5 As shown, in order to achieve lightweight of the whole machine, the middle wall of the first running wheel 401 and the second running wheel 402 is hollowed out and reinforced with ribs, so as to reduce the weight while ensuring the strength, and is made of lightweight materials such as ABS or engineering plastics; in addition, in this embodiment, the support plate 102 is also made of wear-resistant plastics such as engineering plastics, and the specific material can be adaptively adjusted according to the conventional selection of technicians in this field, and no further limitation is made here.

[0032] The driving unit 2 includes an output shaft 201 and an intermediate shaft 202 disposed on the frame 101 and drivingly connected to the output shaft 201. Figure 1-Figure 3 and Figure 6 As shown, the output shaft 201 and the intermediate shaft 202 are connected by a transmission belt 503. The intermediate shaft 202 is rotatably arranged on the frame 101, and a first bevel gear is arranged after the lower end of the intermediate shaft 202 passes through the mounting plate of the frame 101. The end of the drive shaft 103 placed on one side of the intermediate shaft 202 is fixed with a second bevel gear meshing with the first bevel gear, so that the power of the output shaft 201 is transmitted to the drive shaft 103 through the intermediate shaft 202, so that the drive shaft 103 can rotate along the intermediate shaft 202. Figure 1 The direction shown is counterclockwise rotation, so that the travel unit 4 moves in the direction of the trimmer.

[0033] The first bevel gear and the second bevel gear constitute a gear unit 203. The first bevel gear is fixed to the lower end of the intermediate shaft 202. After the trimmer is started normally, the output shaft 201 rotates to transmit power to the drive shaft 103, so that it moves in the direction of the trimmer. When the output shaft 201 is reversed, the drive shaft 103 drives the walking unit 4 to move in the direction of the trimmer. Figure 1 The direction shown is clockwise, so that the mower moves backward in the direction of travel.

[0034] To achieve lightweight of the whole machine, the gear unit 203, the driving shaft 103 and the driven shaft 104 can all be made of lightweight materials, such as aluminum, engineering plastics and other metal or non-metal lightweight materials.

[0035] In this embodiment, when the tea leaves and branches pruned by the trimmer are deeper, that is, the deeper they are below the surface of the tea leaves, the thicker the pruned branches are, the greater the pruning resistance is. At this time, the trimming speed of the trimmer needs to be appropriately reduced. In order to appropriately reduce the walking speed of the walking unit 4 when pruned thicker branches, a speed change assembly 5 is arranged on the intermediate shaft 202 in this embodiment. Specifically, the speed change assembly 5 includes a first speed change wheel 501 and a second speed change wheel 502 rotatably mounted on the intermediate shaft 202; the first speed change wheel 501 and the second speed change wheel 502 are connected to the output shaft 201 through a transmission belt 503, the wheel diameter of the first speed change wheel 501 is larger than that of the second speed change wheel 502, and the transmission belt 503 includes a large wheel belt connected to the first speed change wheel 501 and a small wheel belt connected to the second speed change wheel 502. The above-mentioned transmission connection can be connected by a belt and pulley, or by a synchronous wheel and synchronous belt, which will not be described in detail here.

[0036] The intermediate shaft 202 is provided with a sliding key 504, and the intermediate shaft 202 is provided with a long key groove, and the sliding member 504 is slidably arranged on the long key groove; the inner holes of the first speed change wheel 501 and the second speed change wheel 502 are both provided with key holes that can be matched with the sliding member 504, and the upper end of the sliding member 504 is provided with a convex key 506 that reciprocates with the above-mentioned key hole, that is, by sliding the sliding key 504 in the long key groove, the convex key 506 is respectively matched with the first speed change wheel 501 and the second speed change wheel 502, as shown in FIG. Figure 3 As shown; when the convex key 506 cooperates with the first speed wheel 501, the output shaft 201 transmits power to the intermediate shaft 202 through the first speed wheel 501. At this time, the transmission speed of the intermediate shaft 202 is relatively low, thereby reducing the traveling speed of the walking unit 4; when the convex key 506 cooperates with the second speed wheel 502, the output shaft 201 transmits power to the intermediate shaft 202 through the second speed wheel 502. At this time, the transmission speed of the intermediate shaft 202 is relatively high, thereby increasing the traveling speed of the walking unit 4; initially, the convex key 506 is in a state of cooperating with the second speed wheel 502.

[0037] The frame body 101 is provided with a driving push rod 505 for driving the sliding key 504 to slide. The driving push rod 505 adopts a miniature electric push rod. Specifically, the upper end of the sliding key 504 is provided with a convex key 506, and the lower end is provided with a driving groove 507. A driving plate 508 is rotatably sleeved on the intermediate shaft 202, and the inner hole of the driving plate 508 is rotatably engaged with the driving groove 507; the driving rod end of the driving push rod 505 is fixedly connected with the driving plate 508, and the driving rod seat is fixed on the frame body 101. After the driving push rod 505 is started, the driving sliding key 504 slides to make the convex key 506 on it cooperate with the first speed change wheel 501, thereby reducing the speed of the intermediate shaft 202.

[0038] The frame 101 is provided with a detection unit 6 extending forward at the forward end of the trimmer. The detection unit 6 includes a detection frame 602 fixed on the frame 101. The lower end of the detection frame 602 is fixed on the frame 101 and extends upward for a distance and then extends toward the forward end of the trimmer. A distance detector 601 is installed at the end of its front end. Figure 4 As shown, the distance detector 601 is used to detect the distance between it and the upper surface of the unpruned tea tree. When it receives the signal from the surface of the tea tree, the pruning depth of the surface at this time has reached the speed reduction depth, thereby triggering the drive push rod 505 to start and drive the sliding key 504 to a state of matching with the first speed change wheel 501.

[0039] The distance detector 601 is slidably arranged on the detection frame 602, and sliding rods are symmetrically arranged on both sides of the upper end surface of the distance detector 601. The sliding rods are slidably arranged through the front end plate of the detection frame 602, and a button 603 matching the upper end surface of the distance detector 601 is arranged on the lower end surface of the front end plate of the detection frame 602. The button 603 is electrically connected to the driving unit 2. When the distance detector 601 is touched by the upper surface of the tea tree, the button can be triggered to reverse the output shaft 201. At this time, the walking unit 4 drives the trimmer to move in the reverse direction to prompt the operator to prevent the trimmer from trimming too deep.

[0040] In this embodiment, the pruned branches and leaves are placed above the support plate 102, and fall directly onto the pruned tea tree after being piled up, thereby affecting the pruning efficiency and the subsequent collection of the pruned branches and leaves. In order to improve the collection efficiency of the pruned branches and leaves, in this embodiment, a conveying component 7 is provided on the frame 101, such as Figure 7 As shown, the conveying assembly 7 includes a conveying plate 701 , which is rotatably disposed above the walking unit 4 and covers the entire upper area of ​​the support plate 102 .

[0041] The end of the conveying plate 701 away from the holding part 1 is rotatably set on one side of the frame 101 through a pin shaft 703, and is matched with the driving shaft 103 near the holding part 1. A cam 702 is fixedly arranged at the end of the driving shaft 103 near the holding part 1. After the cam 702 rotates with the driving shaft 103, it intermittently contacts and lifts the conveying plate 701, so that one end of the conveying plate 701 rotates and the other end is reciprocatedly lifted, so that the conveying plate 701 tilts downward from the lifted end to the end of the pin shaft 703, and the branches and leaves fallen on the conveying plate 701 are slid and transported to the end away from the holding part 1, and after sliding out of the conveying plate 701, they are placed in the open space between the tea trees for easy collection.

[0042] In this embodiment, in order to achieve stability of the conveying plate 701 at one end of the lifting, a cam 702 can be synchronously set on the driven shaft 104. Since the driven shaft 104 and the driving shaft 103 are in a synchronous rotation state, the rotation state of the cam 702 is also the same, thereby achieving synchronous lifting of both sides of the conveying plate 701 and improving stability.

[0043] In this example, the axes of the driving shaft 103 and the driven shaft 104 are arranged in parallel, which is a conventional arrangement method used by those skilled in the art and will not be described in detail herein. In addition, a power supply for providing weak electricity may be arranged on the gripping portion 1, and a small DC power generation component may be driven by the driving unit 2 to generate electricity, thereby providing weak electricity for the micro push rod, distance detector 601 and buttons, etc. This is also a conventional arrangement and will not be described further herein.

[0044] The pruning process of pruning tea leaves using the tea pruning machine with the telescopic adjustment mechanism as described above is as follows: S1: The operator holds the tea leaf trimmer through the gripping part 1 and trims the branches and leaves of the tea leaves through the trimming tool 3; S2: After the pruning tool 3 prunes the tea leaves, the walking unit 4 is placed on the upper surface of the pruned tea tree. While the pruning tool 3 continues to prune, the walking unit 4 allows the pruning machine as a whole to crawl on the upper surface of the tea tree, thereby saving the labor of the operator; S3: The distance detector 601 on the detection unit 6 detects the distance from the upper surface of the unpruned tea tree, thereby adjusting the matching relationship between the intermediate shaft 202 and the speed change assembly 5 through the driving push rod 505 to adjust the rotation speed of the driving shaft 103 and change the walking speed of the walking unit 4; S4: According to the width of the tea trees, the distance between adjacent traveling units 4 is adjusted by telescopically sliding the traveling unit 4 relative to the driving shaft 103 and the driven shaft 104 to adapt to tea trees of different widths.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
