Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 A pruning device for tea cultivation includes a handle 1, with a mounting shell 2 fixedly connected to the upper end of the handle 1. A cover 3 is provided at the right end of the mounting shell 2. Multiple heat dissipation holes 4 are provided on the surface of the cover 3, arranged in a circular array on the cover 3. The heat dissipation holes 4 ensure good heat dissipation of the servo motor 5. The servo motor 5 is fixedly installed at the left end of the cover 3. The output shaft of the servo motor 5 is rotatably connected to the mounting shell 2. A pruning blade 6 is fixedly connected to the output shaft of the servo motor 5.

[0025] Please see Figure 1 , Figure 2, Figure 5 A protective mechanism 7 is provided on the side of the mounting shell 2. The protective mechanism 7 includes a fixing plate 71. The fixing plate 71 is fixedly connected to the side of the mounting shell 2. An insert plate 72 is slidably connected to the inner wall of the fixing plate 71. An insert rod 73 is slidably connected to the end piece of the fixing plate 71. The insert rod 73 is slidably connected to the insert plate 72. An end ring 74 is fixedly connected to the upper end of the insert rod 73. An elastic rope 75 is glued to the lower side of the end ring 74. The other end of the elastic rope 75 is glued to the end piece of the fixing plate 71. A protective cover 76 is fixedly connected to the left end of the insert plate 72. The protective cover 76 is in contact with the trimmer 6. The protective cover 76 can protect the trimmer 6 when it is not in use. The protective cover 76 can be stabilized by the insert rod 73, insert plate 72 and other structures, and is used to protect the trimmer 6.

[0026] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 A guide mechanism 8 is provided on both the mounting housing 2 and the output shaft of the servo motor 5. The guide mechanism 8 includes an annular groove 81. An annular groove 81 is provided on the inner side wall of the mounting housing 2. A guide block 82 is fixedly connected to the output shaft of the servo motor 5. A guide plate 83 is slidably connected to the inner wall of the guide block 82. The guide plate 83 is slidably connected to the mounting housing 2. A guide ball 84 is fixedly connected to the vertical part of the guide plate 83. The guide ball 84 is slidably connected to the annular groove 81. A spring 85 is provided on the outer side of the vertical part of the guide plate 83. Through the combined use of the annular groove 81, the guide ball 84 and other structures, the output shaft of the servo motor 5 can be rotated and guided to ensure the rotational stability of the output shaft, the trimming tool 6 and other structural components.

[0027] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 There are two guide blocks 82, which are symmetrically distributed on the output shaft of the servo motor 5. The guide blocks 82 can be used to install the guide plate 83. One end of the spring 85 is welded to the guide block 82, and the other end of the spring 85 is welded to the horizontal part of the guide plate 83. The guide plate 83 can be connected by the spring 85.

[0028] The specific implementation process of this utility model is as follows: In use, the output shaft is driven to rotate by the servo motor 5, which in turn drives the pruning blade 6 to rotate, so as to prune the branches and leaves of the tea tree. When the output shaft of the servo motor 5 rotates, it can drive the guide block 82 to rotate, which in turn drives the guide plate 83 to rotate, and then drives the guide ball 84 to slide along the inner wall of the annular groove 81, so as to guide and limit the output shaft of the servo motor 5. Under the deformation of the spring 85, the guide plate 83 can be pushed to drive the guide ball 84 to always be in contact with the annular groove 81 to ensure a good guiding effect.

[0029] When the trimmer 6 is idle, the end ring 74 can be pulled upward to move the insert rod 73. The elastic rope 75 deforms and pushes the protective cover 76 to contact the trimmer 6, thus blocking the trimmer 6 and allowing the insert plate 72 to pass through the fixed plate 71. Then, the end ring 74 is released to allow the elastic rope 75 to return to its original shape, so that the insert rod 73 can be pulled to insert into the insert plate 72, limiting the position of the insert plate 72 and keeping the protective cover 76 stable, thus achieving a good protective effect.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
