Technical Field

[0001] This utility model relates to the technical field of fruit planting branch and leaf pruning devices, and in particular to a fruit planting branch and leaf pruning device with an extension and adjustment structure. Background Technology

[0002] In fruit cultivation, some branches and leaves need to be pruned, and pruning requires a fruit cultivation branch and leaf pruning device. Publication number CN219803090U discloses a branch and leaf pruning device for fruit cultivation. This device includes a support rod and a pruning mechanism. A fixing ring is fixedly connected to the outer side of the support rod, and an arm is provided on the outer side of the support rod. The pruning mechanism is located at one end of the support rod and includes a motor, a rotating shaft, and a rotating handle. The motor is located at one end of the support rod, and the rotating shaft is located at the output end of the motor. A rotating handle is fixedly connected to the side of the rotating shaft away from the motor. A first rotating rod is hinged to one side of the rotating handle, and a second rotating rod is hinged to the side of the first rotating rod away from the rotating handle. The fruit pruning equipment provided by this utility model solves the problem of low pruning efficiency caused by the need for manual pruning in existing devices. However, in actual pruning, tall branches are often encountered, and using a ladder is unsafe. Furthermore, the cutting parts are frequently worn due to cutting hard branches. Traditional pruning devices have integrated blades and handles that are difficult to replace when damaged, making maintenance cumbersome. This device does not offer effective solutions to these issues and needs improvement. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems mentioned in the background art.

[0004] This utility model adopts the following technical solution: a fruit planting branch and leaf pruning device with an extension and adjustment structure, including a main rod, a middle rod slidably connected to the inner wall of the main rod, a turntable rotatably connected to the side of the main rod, a lead screw fixedly connected to the top of the turntable, a first sliding groove formed on the surface of the middle rod, a constraint block fixedly connected to the inner wall of the main rod, a fixed blade slidably connected to one end of the main rod, a rotating blade slidably connected to the side of the fixed blade, a pin slidably connected to the through groove of the main rod, a handle slidably connected to one end of the rotating blade, an electric cylinder bracket fixedly connected to the surface of the middle rod, an electric cylinder fixedly connected to the surface of the electric cylinder bracket, a second sliding groove formed on the surface of the handle, and a slider slidably connected to the surface of the second sliding groove.

[0005] Preferably, the surface of the lead screw is threadedly connected to the middle rod, and the surface of the constraint block is slidably connected to the first slide groove. This allows the lead screw to rotate by rotating the turntable, thereby causing the middle rod to extend and retract under the action of the constraint block and the slide groove.

[0006] Preferably, the surface of the pin is rotatably connected to both the fixed blade and the rotating blade. This allows the fixed blade and the rotating blade to rotate on the pin.

[0007] Preferably, the surface of the turntable is engraved with anti-slip texture, and the groove of the knife handle is slidably connected to the pin. Here, the anti-slip texture makes the turntable easier to rotate, and the pin can fix the knife handle and the rotating blade in place.

[0008] Preferably, the output end of the electric cylinder is rotatably connected to the slider. This ensures that the slider does not affect the extension and retraction of the electric cylinder's output end.

[0009] Preferably, a camera bracket is fixedly connected to the surface of the central pole, a camera is fixedly connected to the surface of the camera bracket, a screen bracket is fixedly connected to the surface of the main pole, and a display screen is fixedly connected to the surface of the screen bracket. Here, the camera is fixed to the central pole, and the screen is fixed to the main pole.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. In this utility model, the rotating turntable drives the lead screw to rotate, thereby allowing the middle rod to extend and retract within the main rod. This allows the overall length of the device to be adjusted according to the location of the branches and leaves. The pin can be quickly removed by pinching it, so that the device can be quickly disassembled when the blade is severely worn or even damaged, facilitating the maintenance of the device.

[0012] 2. In this utility model, the camera bracket, camera, screen bracket and display screen enable the device to observe the pruning of branches and leaves using the camera and display screen, thereby replacing some of the time that needs to be spent looking up, making the pruning operation easier.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1

[0024] Please see Figure 1-6This utility model provides a technical solution: a fruit planting branch and leaf pruning device with an extension and adjustment structure, including a main rod 1, a middle rod 2 slidably connected to the inner wall of the main rod 1, allowing the middle rod 2 to slide within the main rod 1 to adjust the length of the device, a turntable 3 rotatably connected to the side of the main rod 1, and a lead screw 4 fixedly connected to the top of the turntable 3, so that rotating the turntable 3 drives the lead screw 4 to rotate, a first sliding groove 5 is formed on the surface of the middle rod 2, and a constraint block 6 is fixedly connected to the inner wall of the main rod 1, so that the middle rod 2 can only move and extend linearly and prevent it from sliding out of the main rod 1, a fixed blade 7 is slidably connected to one end of the main rod 1, and a rotating blade 8 is slidably connected to the side of the fixed blade 7, so that the fixed blade 7 and the rotating blade 8 can cut off branches and leaves, a pin 9 is slidably connected to the through groove of the main rod 1, a handle 10 is slidably connected to one end of the rotating blade 8, and an electric cylinder 12 bracket 11 is fixedly connected to the surface of the middle rod 2. An electric cylinder 12 is fixedly connected to the surface, thus fixing the electric cylinder 12 to the middle rod 2. A second sliding groove 17 is opened on the surface of the tool holder 10, and a slider 18 is slidably connected to the surface of the second sliding groove 17. The surface of the lead screw 4 is threadedly connected to the middle rod 2. The surface of the constraint block 6 is slidably connected to the first sliding groove 5, so that the lead screw 4 is rotated by rotating the turntable 3, thereby allowing the middle rod 2 to extend and retract under the action of the constraint block 6 and the sliding groove. The surface of the pin 9 is rotatably connected to the fixed blade 7 and the rotating blade 8, so that the fixed blade 7 and the rotating blade 8 can rotate on the pin 9. The surface of the turntable 3 is engraved with anti-slip texture 19. The groove of the tool holder 10 is slidably connected to the pin 9, so that the anti-slip texture 19 makes the turntable 3 easier to rotate. The pin 9 can fix the tool holder 10 and the rotating blade 8. The output end of the electric cylinder 12 is rotatably connected to the slider 18, so that the slider 18 will not affect the extension and retraction of the output end of the electric cylinder 12.

[0025] Example 2

[0026] Please see Figure 1-6 A camera bracket 13 is fixedly connected to the surface of the middle pole 2, and a camera 14 is fixedly connected to the surface of the camera bracket 13. A screen bracket 15 is fixedly connected to the surface of the main pole 1, and a display screen 16 is fixedly connected to the surface of the screen bracket 15. This allows the camera 14 to be fixed on the middle pole 2 and the screen to be fixed on the main pole 1. The trimming can be observed through the camera 14 and the screen without having to keep looking up.

[0027] Working principle: The device achieves length extension adjustment through the sliding connection between the main rod 1 and the middle rod 2. Rotating the turntable 3 with anti-slip texture 19 drives the lead screw 4 to rotate. Since the lead screw 4 and the middle rod 2 are threadedly connected, and the middle rod 2 is restricted by the sliding of the constraint block 6 in the first slide groove 5, it can only move linearly. Therefore, the rotation of the lead screw 4 will cause the middle rod 2 to extend and retract along the inner wall of the main rod 1 under the combined action of the constraint block 6 and the slide groove, thereby adjusting the working length of the entire device. When pruning is needed, the fixed blade 7 and the rotating blade 8 are connected by a pin 9 and can rotate on the pin 9. The electric cylinder 12 is fixed on the electric cylinder 12 bracket 11 of the middle rod 2, and its output end is rotatably connected to the slider 18. The slider 18 slides in the second groove 17 of the handle 10. When the electric cylinder 12 works, it pushes the handle 10 through the slider 18, which in turn drives the rotating blade 8 to slide relative to the fixed blade 7, thus achieving the cutting of branches and leaves. In addition, a camera 14 is fixed on the camera bracket 13 on the middle rod 2, and a display screen 16 is fixed on the screen bracket 15 on the main rod 1. Users can observe the pruning situation in real time through the camera 14 and the display screen 16 without having to constantly look up, which improves the accuracy of pruning and the convenience of operation. Through this series of ingenious designs, the entire device achieves the function of pruning branches and leaves with adjustable length, flexible angle, simple operation, and visual assistance.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
