Description

Technical Field

[0001] This utility model relates to the field of chestnut tree planting technology, specifically a high-altitude branch cutter for chestnut tree pruning. Background Technology

[0002] In the process of chestnut tree planting and management, proper pruning of high branches is an important step in ensuring the healthy growth of trees and improving fruit yield and quality. A branch cutter is needed in the pruning process.

[0003] Patent CN216452051U discloses a high-branch pruning device, including a sleeve rod. An extension rod is provided at the top of the sleeve rod, and a mounting base is fixedly connected to the top of the extension rod. Sleeves are fixedly connected to both sides of the top of the mounting base. A spring is fixedly connected to the bottom of the inner cavity of the sleeve. A movable block is fixedly connected to the top of the spring. A buffer rod is fixedly connected to the top of the movable block. The top of the buffer rod extends to the outside of the sleeve. An electric push rod is fixedly connected to the top of the mounting base.

[0004] Although this device, through the coordinated use of a sleeve, extension rod, mounting base, sleeve, spring, movable block, buffer rod, electric push rod, fixing plate, blade, mounting plate, and saw teeth, can effectively solve the problem of the relatively simple structure and inefficiency of traditional high-branch pruning devices, it still requires manual pruning of branches. This method is labor-intensive and inefficient. Furthermore, the device has limitations in adjusting the height and angle of the saw teeth, failing to meet diverse pruning needs and resulting in poor pruning effects, which negatively impacts the subsequent growth of chestnut trees. Therefore, we propose a high-altitude branch cutter for chestnut tree pruning. Utility Model Content

By setting up a lifting plate, a flipping mechanism, a rotating mechanism, and an electric cylinder, it solves the problems of adjusting the cutting height, horizontal angle, and angle with the ground of the circular saw blade, thereby effectively dealing with chestnut tree branches in different growth stages, reducing the risk of manual climbing and pruning, and improving the safety and efficiency of pruning operations.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-altitude branch cutter for chestnut tree pruning includes a working board with several support columns fixed to its bottom end.

The device also includes:

[0008] A flipping mechanism is installed on the top surface of the work plate and is used to drive the lifting plate to flip. The flipping mechanism includes a flipping plate rotatably connected to the top surface of the work plate and an electric push rod installed on the bottom surface of the work plate for driving the flipping plate to flip.

[0010] In a preferred embodiment, L-shaped push-pull rods are fixed on both the front and rear surfaces of the work plate, and a handle is installed on the right side surface of the crossbar end of the push-pull rod.

[0011] This design gives the device mobility and stability, making it easy to transport and position. The L-shaped push-pull rod and handle allow operators to push and control the device more easily and effortlessly.

The flipping plate is rotatably connected to the two upright plates via a rotating rod. The rod body of the electric push rod is installed on the bottom surface of the working plate. The piston rod of the electric push rod passes through the bottom surface of the working plate and extends to the top of the working plate. A limiting groove is provided on the bottom surface of the flipping plate in a horizontally arranged manner. The flipping mechanism also includes a limiting block hinged to the top surface of the piston rod of the electric push rod and slidably connected to the limiting groove on the bottom surface of the flipping plate.

[0015] In a preferred embodiment, the longitudinal cross-sectional shape of the upper limit groove on the bottom surface of the flip plate is I-shaped, and the shape of the limiting block is I-shaped to match the shape of the upper limit groove on the bottom surface of the flip plate.

[0016] These two features enable the lifting plate to be flipped, adjusting the angle between the circular saw blade and the ground to accommodate tree branch trimming at different angles, making the flipping process more stable and ensuring operational safety.

[0017] In a preferred embodiment, the rotating mechanism further includes two gears located between the turntable and the lifting plate and meshing with each other, a rotating shaft coaxially connected to the output shaft of the rotating motor, and the two gears are respectively coaxially fixed on the outer circumferential wall of the rotating shaft and the rotating roller.

[0020] In a preferred embodiment, the cylinder body of the electric cylinder is installed at the middle position of the top surface of the tilting plate, and the piston rod of the electric cylinder is fixed at the middle position of the bottom surface of the lifting plate.

[0033] 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.

[0034] Please see Figure 1 The present invention provides a technical solution: a high-altitude branch cutter for chestnut tree pruning, including a working plate 1, a number of support columns 11 fixed at the bottom of the working plate 1, a support plate 12 fixed at the bottom of the support columns 11, a universal wheel 13 installed at the bottom of the support plate 12, and a lifting plate 2 provided above the working plate 1.

[0035] The device is equipped with good mobility and stability through the working plate 1, support column 11, support plate 12 and casters 13. The staff can easily push the device to move between different work locations and quickly reach the chestnut tree pruning position, saving manpower and time costs and facilitating the transportation and positioning of the device.

[0036] The front and rear surfaces of the work plate 1 are both fixed with L-shaped push-pull rods 14, and a handle 15 is installed on the right side surface of the cross bar end of the push-pull rod 14.

[0037] The L-shaped push-pull rod 14 and handle 15 make it more comfortable for operators to hold and easier to apply force. They can better control the direction and force when pushing the device, especially in narrow or complex terrain, which greatly improves the convenience and flexibility of device operation.

[0038] In this embodiment, as Figures 1-2 As shown, a cutting mechanism 3 is provided above the work plate 1. The cutting mechanism 3 includes a mounting block 31 located above the work plate 1 and a circular saw blade 33 mounted on the outer wall of the mounting block 31 for cutting branches.

[0039] The cutting mechanism 3 also includes a cutting roller 32 rotatably connected to the mounting block 31, a cutting motor 34 mounted on the right side surface of the mounting block 31 and whose output shaft is coaxially connected to the cutting roller 32, and a circular saw blade 33 coaxially fixed to the outer circumferential wall of the cutting roller 32 near the left end.

[0040] Through the mounting block 31, cutting roller 32, circular saw blade 33 and cutting motor 34 in the cutting mechanism 3, the cutting motor 34 provides power to the cutting roller 32, driving the circular saw blade 33 to rotate at high speed, thereby achieving efficient and precise cutting of chestnut tree branches and ensuring the quality of pruning operations.

[0041] In addition, such as Figure 1 , Figures 3-4As shown, it also includes: a flipping mechanism 4, which is set on the top surface of the work plate 1 and is used to drive the lifting plate 2 to flip. The flipping mechanism 4 includes a flipping plate 42 rotatably connected to the top surface of the work plate 1 and an electric push rod 44 installed on the bottom surface of the work plate 1 and used to drive the flipping plate 42 to flip.

[0042] The flipping mechanism 4 also includes two upright plates 41 fixed on the top surface of the working plate 1 near the right end. The flipping plate 42 is rotatably connected to the two upright plates 41 through the rotating rod 43. The rod body of the electric push rod 44 is installed on the bottom surface of the working plate 1. The piston rod of the electric push rod 44 passes through the bottom surface of the working plate 1 and extends to the top of the working plate 1. The bottom surface of the flipping plate 42 is provided with a horizontally arranged limiting groove. The flipping mechanism 4 also includes a limiting block 45 hinged to the top surface of the piston rod of the electric push rod 44 and slidably connected to the limiting groove on the bottom surface of the flipping plate 42.

[0043] Through the upright plate 41, flip plate 42, rotating rod 43, electric push rod 44 and limit block 45 in the flipping mechanism 4, when the electric push rod 44 extends and retracts, it drives the flip plate 42 to flip around the rotating rod 43, thereby adjusting the angle between the circular saw blade 33 and the ground to meet the pruning needs of branches with different inclination angles.

[0044] The longitudinal cross-sectional shape of the upper limit groove on the bottom surface of the flip plate 42 is I-shaped, and the shape of the limiting block 45 is I-shaped to match the shape of the upper limit groove on the bottom surface of the flip plate 42.

[0045] Through the matching structure of the I-shaped limiting groove and the limiting block 45, the limiting block 45 slides stably in the limiting groove during the flipping process of the flipping plate 42, effectively preventing the flipping plate 42 from shifting or shaking, and ensuring the smoothness and safety of the flipping operation.

[0046] Furthermore, such as Figure 1 , Figures 5-6 As shown, it also includes: a rotating mechanism 5, which is disposed on the top surface of the lifting plate 2 and is used to drive the mounting block 31 to rotate. The rotating mechanism 5 includes a rotating roller 52 rotatably connected to the top surface of the lifting plate 2, a turntable 51 coaxially fixed on the top surface of the rotating roller 52, and a rotating motor 53 installed on the top surface of the lifting plate 2 and used to drive the turntable 51 to rotate. The mounting block 31 is fixed at the middle position on the top surface of the turntable 51.

[0047] The rotating mechanism 5 also includes two gears 54 located between the turntable 51 and the lifting plate 2 and meshing with each other, and a rotating shaft 55 coaxially connected to the output shaft of the rotating motor 53. The two gears 54 are respectively coaxially fixed on the outer circumference of the rotating shaft 55 and the rotating roller 52.

[0048] The rotating mechanism 5 consists of a rotating roller 52, a turntable 51, a rotating motor 53, a gear 54, and a rotating shaft 55. The rotating motor 53 drives the rotating shaft 55 to rotate, and the rotating roller 52 and the turntable 51 are driven to rotate through the meshing transmission of the gear 54, thereby realizing the horizontal rotation of the mounting block 31 and the circular saw blade 33 and expanding the trimming range.

[0049] The top surface of the lifting plate 2 is provided with an annular guide groove, and several guide rods 56 are fixed on the bottom surface of the turntable 51. Guide blocks 57 that are slidably connected to the guide groove on the top surface of the lifting plate 2 are fixed on the bottom surface of the guide rods 56.

[0050] The guide groove on the top surface of the lifting plate 2, the guide rod 56 on the bottom surface of the turntable 51, and the guide block 57 allow the turntable 51 to rotate. The guide block 57 slides in the guide groove to provide guidance and support for the turntable 51, ensuring that the turntable 51 rotates smoothly and improving the accuracy and stability of the circular saw blade 33 rotation.

[0051] Specifically, such as Figure 1 , Figure 5 As shown, an electric cylinder 6 is provided above the working plate 1 to drive the lifting plate 2 to move up and down. The cylinder body of the electric cylinder 6 is installed at the middle position of the top surface of the flip plate 42, and the piston rod of the electric cylinder 6 is fixed at the middle position of the bottom surface of the lifting plate 2.

[0052] The cylinder body and piston rod of the electric cylinder 6 are connected to the tilting plate 42 and the lifting plate 2 respectively. When the piston rod of the electric cylinder 6 extends and retracts, the lifting height of the lifting plate 2 can be precisely controlled, thereby flexibly adjusting the trimming height of the circular saw blade 33 to adapt to the trimming work of chestnut tree branches of different heights.

[0053] It should be added that the cutting motor 34, electric push rod 44, rotary motor 53, and electric cylinder 6 are all electrically connected to the external PLC via wires, and the cutting motor 34, electric push rod 44, rotary motor 53, and electric cylinder 6 are all electrically connected to the external power supply via wires, and the external PLC is also electrically connected to the external power supply via wires.

[0054] Finally, it should be noted that the cutting motor 34, electric push rod 44, rotary motor 53, electric cylinder 6 and other components involved in this utility model are all general standard parts or components known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle of this utility model. The electrical connection between each electrical component is completed in the order of operation. The detailed connection method is a technology known in the art.

[0055] In this embodiment, during actual use, the operator moves the device to the chestnut tree pruning position using the push-pull rod 14 and handle 15, with the help of the casters 13. Then, the external PLC sends a command to start the electric cylinder 6. The piston rod of the electric cylinder 6 extends and retracts, driving the lifting plate 2 to rise and fall, adjusting the cutting mechanism 3 to a suitable height. Then, the electric push rod 44 is controlled to extend and retract, pushing the flipping plate 42 to flip around the rotating rod 43, adjusting the angle between the circular saw blade 33 and the ground.

[0056] Once the height and angle are adjusted to the correct position, the external PLC controls the start of the rotary motor 53, which, through the meshing transmission of the gear 54, drives the rotating roller 52 and the turntable 51 to rotate, causing the mounting block 31 and the circular saw blade 33 to rotate horizontally and align with the branches to be pruned. Finally, the external PLC controls the start of the cutting motor 34, which drives the cutting roller 32 to rotate the circular saw blade 33 at high speed, completing the cutting of the chestnut tree branches.

[0057] Throughout the trimming process, the guide groove, guide rod 56, and guide block 57 ensure that the turntable 51 rotates smoothly, while the I-shaped limiting groove and limiting block 45 ensure that the flipping plate 42 flips stably, thus ensuring that the trimming operation is carried out efficiently and safely.

[0058] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
