[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the utility model will now be described in further detail with reference to the accompanying drawings and the following embodiments, so that the public can better understand the implementation method of this utility model. The specific implementation scheme of this utility model is as follows: A fixed-width multi-angle pruning machine includes a carrier 1. The carrier 1 is hinged to a support 2 and a telescopic component A3. The two ends of the telescopic component A3 are hinged to the carrier 1 and the support 2, respectively, to drive the support 2 to rotate around the hinge point with the carrier 1. The support 2 is connected to a boom 4 through a telescopic structure 5, and the boom 4 can extend to the left or right side of the carrier 1 with the help of the telescopic mechanism 5. The boom 4 is rotatably connected to a connecting frame 6, which is hinged to a pruning mechanism 7. A telescopic component B8 is connected between the pruning mechanism 7 and the connecting frame 6, and the two ends of the telescopic component B8 are hinged to the pruning mechanism 7 and the connecting frame 6, respectively. First, the height of the pruning mechanism 7 is adjusted by the bracket 2. The bracket 2 is connected to the boom 4 through the telescopic structure 5, so that the boom 4 can extend to the side of the carrier vehicle 1. Then, the pruning mechanism is adjusted by the telescopic component B, so that the pruning mechanism can prune the top, side and other positions of the green plants at multiple angles. When not in operation, the pruning mechanism 7 can be retracted to the side of the bracket 2 to reduce the obstruction of the front view. The bracket 2 can also play a certain protective role when the branches fall, thus improving safety.

[0018] Specifically, the support 2 includes a connecting beam 21 and two parallel longitudinal fixed beams 22. The two longitudinal fixed beams 22 are connected by the connecting beam 21 to form a frame structure. The rear end of the frame is hinged to the carrier vehicle 1. The longitudinal fixed beams 22 extend along the straight running direction of the carrier vehicle 1, and the support 2 can cover the lower part of the carrier vehicle 1, playing a certain protective role and preventing large tree branches from pressing on the carrier vehicle. The longitudinal fixed beams 22 are hollow, and a movable beam 23 is slidably fitted inside the longitudinal fixed beams 22. A telescopic component C9 is also provided to drive the movable beam 23 to move. The two ends of the telescopic component C9 are hinged to the movable beam 23 and the longitudinal fixed beam 22 respectively. Under the drive of the telescopic component C9, the movable beam 23 can extend, and thus can be adjusted according to the height of the green plants.

[0019] It should be noted that the telescopic structure 5 includes a telescopic component D51 and a hollow transverse fixed beam 52 fixedly connected to the moving beam 23. The transverse fixed beam 52 is supported by two moving beams 23, making the structure more stable. The two transverse fixed beams 52 are arranged in parallel. The boom 4 is telescopically fitted inside the transverse fixed beam 52. A rotary drive 13 is fixedly installed at the end of the boom 4 away from the transverse fixed beam 52. The boom 4 is connected to the connecting frame 6 through the rotary drive 13, so that the pruning mechanism can prune the green plants at different positions at multiple angles.

[0020] A protective net 10 is provided on the upper part of the carrier vehicle 1 and on the side near the trimming mechanism 7. The protective net 10 is welded from crisscrossing rods. It can be connected between two longitudinal fixed beams 22 to reduce space occupation, or it can be directly installed on the roof of the carrier vehicle 1 to provide effective protection for the vehicle and the driver. In this embodiment, the carrier vehicle 1 is a tractor.

[0021] The longitudinal fixed beam 22 is fixedly equipped with a support rod 11 that supports the mounting beam 71. The support rod 11 is equipped with a stop 12, which supports and limits the trimming mechanism 7 that is retracted to one side of the bracket 2 when not in operation, thereby improving safety during movement.

[0022] It should be noted that telescopic components A3, B8, C9, and D51 are all hydraulic cylinders.

[0023] Specifically, the pruning mechanism 7 includes a cutting blade 72 and a mounting beam 71 hinged to the boom 4. The mounting beam 71 has several rotating shafts evenly arranged in a rotating manner. The rotating shafts are fixedly connected to the cutting blade 72. The cutting blades 72 are arranged at linear intervals. A triangular partition plate 73 is provided at two adjacent cutting blades 72. The partition plate 73 is fixedly connected to the mounting beam 71. The partition plate can play a guiding role and can divide the branches to the cutting blade 72 for pruning to avoid omissions.

[0024] It is also provided with a power mechanism for driving the rotating shaft to rotate. The power mechanism includes a rotary motor 74 fixedly connected to the mounting beam 71. The output shaft of the rotary motor 74 is connected to a rotating shaft. A pulley 75 is connected to the outside of the rotating shaft by a key. Adjacent pulleys 75 are connected by a belt 76.

[0025] The working principle and process of this utility model are as follows: First, move the carrier vehicle 1 to the predetermined location. Start the hydraulic cylinder 3 to drive the bracket 2 to rotate around the hinge point with the carrier vehicle 1. Start the hydraulic cylinder 9 to push the moving beam 23 out of the longitudinal fixed beam 22 until the front of the bracket 1 is raised to the predetermined height. Start the hydraulic cylinder 51 to push the boom 4 out of the transverse fixed beam 52 to one side of the carrier vehicle 1. Start the rotary motor 74. The rotary motor 74 drives a rotating shaft to rotate. The rotating shaft drives a pulley 75 to rotate. The pulley 75 drives other rotating shafts to rotate through the belt 76, which in turn drives the cutting blade 72 to rotate. The rotary drive 13 drives the connecting frame 6 to rotate the pruning mechanism 7, and the hydraulic cylinder 8 drives the pruning mechanism 7 to prune the green plant crown from multiple angles.
