Description

Technical Field

[0001] This utility model relates to the field of forestry tool technology, and in particular to a portable forestry pruning and positioning device. Background Technology

[0002] Forestry serves as a vital pillar for ecological protection and economic development, and pruning is a crucial operation for maintaining healthy tree growth and optimizing forestry resource output. Portable pruning equipment, with its flexibility and convenience, is widely used in various scenarios such as mountainous areas, orchards, and urban greening. The accuracy of pruning positioning directly impacts the quality of forest maintenance and operational efficiency, driving the development of portable positioning devices towards high efficiency and adaptability to complex working environments.

[0003] In actual forestry pruning operations, when facing high pruning heights, existing portable positioning devices are limited by operating distance and posture. Operators holding the equipment are prone to swaying due to arm fatigue and external interference. This swaying is directly transmitted to the positioning mechanism, leading to decreased positioning accuracy. This not only affects pruning results but may also cause unnecessary damage to the healthy growth of trees. Furthermore, existing devices lack guidance and control mechanisms for the direction of falling branches. The trajectory of falling branches is entirely influenced by gravity and wind, making it difficult for operators to predict the landing point. This can easily injure on-site personnel and damage surrounding seedlings and equipment, posing significant safety hazards.

[0004] Therefore, it is necessary to invent a portable forestry pruning positioning device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the problems of existing devices, such as operator fatigue due to arm support and external interference, which cause shaking when the device is held at high pruning heights. This shaking is directly transmitted to the positioning mechanism, resulting in decreased positioning accuracy, affecting pruning results, and the lack of a guidance and control mechanism for the falling direction of pruned branches, posing a safety hazard. Therefore, this invention provides a portable forestry pruning positioning device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a portable forestry pruning and positioning device, comprising a connecting rod, an extension rod, and a pruning rod connected sequentially from bottom to top by threads. One end of the connecting rod is fixedly connected to a screw rod, one end of the extension rod is provided with a connecting screw hole, and the other end is fixedly connected to a connector. One end of the pruning rod is threadedly connected to the connector through a threaded hole. Threaded sleeves are fixedly connected to both sides of the top of the pruning rod. One threaded sleeve is threadedly connected to a support component for preliminary positioning and support of the pruning rod, and the other threaded sleeve is threadedly connected to a positioning component for fixing the position of the pruning rod. A pruning component for pruning branches is also provided at the top of the pruning rod.

[0007] As a further description of the above technical solution: the positioning component includes a fixed block that is threadedly connected to a threaded sleeve via a first threaded rod. A sliding limiting groove is provided on the surface of the fixed block. A bidirectional lead screw is rotatably connected in the sliding limiting groove. A servo motor with its output end fixedly connected to one end of the bidirectional lead screw is also provided at one end of the fixed block. Two L-shaped rods are threadedly sleeved on the outer side of the bidirectional lead screw. An arc-shaped positioning plate is fixedly connected to the top of the L-shaped rods.

[0008] As a further description of the above technical solution: the support assembly includes a fixed plate that is threadedly connected to a threaded sleeve via a second threaded rod, and an arc-shaped support plate is fixedly connected to the top of the fixed plate.

[0009] As a further description of the above technical solution: both the arc-shaped positioning plate and the arc-shaped support plate are provided with anti-slip rubber sheets.

[0010] As a further description of the above technical solution: the pruning assembly includes a fixed pruning blade fixedly connected to the top of the pruning rod, and a rotating pruning blade is rotatably connected to the fixed pruning blade via a first rotating shaft, and a clearance groove is provided at the bottom of the rotating pruning blade.

[0011] As a further description of the above technical solution: the pruning assembly also includes a mounting plate fixedly connected to the inner wall of the pruning rod, an electric push rod is provided on the mounting plate, the output end of the electric push rod is fixedly connected to a drive rod through a connecting block, and a sliding rod with one end passing through the relief groove (44) is fixedly connected to the top of the drive rod.

[0012] As a further description of the above technical solution: a control rod is fixedly connected to the other end of the connecting rod. The control rod has an integrated control circuit board inside and a control button embedded on its surface. A handle is fixedly connected to one end of the control rod. A battery cavity is provided inside the handle. A cover plate is threadedly connected to one end of the handle.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. This utility model incorporates a support component and a positioning component. During actual use, the operator can control the movement of the fixing plate and the arc-shaped support plate to the branch to be pruned using the handle, extension rod, and pruning rod. Then, the positions of the arc-shaped support plate, the pruning component, and the positioning component are adjusted to the pruning position. The arc-shaped support plate is then pressed against the branch for initial positioning. The operator then activates the servo motor to rotate the bidirectional lead screw. The rotation of the bidirectional lead screw causes two L-shaped rods to move in opposite directions, thereby moving the two arc-shaped support plates and clamping and fixing the branch. This completes the pruning positioning, preventing shaking caused by operator fatigue or external interference when holding the equipment, which could lead to a shift in the pruning position. Simultaneously, the clamping mechanism controls the falling direction of the pruned branch, preventing it from falling and injuring the operator or the equipment.

[0017] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-6 This utility model provides a technical solution: a portable forestry pruning and positioning device, comprising a connecting rod 1, an extension rod 2, and a pruning rod 3 connected sequentially from bottom to top by threads. One end of the connecting rod 1 is fixedly connected to a screw 11, and the other end is fixedly connected to a control rod 12. The control rod 12 integrates a control circuit board and has control buttons embedded on its surface. One end of the control rod 12 is fixedly connected to a handle 13, which contains a battery cavity. One end of the handle 13 is threadedly connected to a cover plate 14. The extension rod 2... One end is provided with a connecting screw hole 21, and the other end is fixedly connected with a connector 22. One end of the pruning rod 3 is threadedly connected to the connector 22 through a threaded hole. Threaded sleeves 31 are fixedly connected to both sides of the top of the pruning rod 3. One threaded sleeve 31 is threadedly connected to a support component 6 for initial positioning and support of the pruning rod 3, and the other threaded sleeve 31 is threadedly connected to a positioning component 5 for fixing the position of the pruning rod 3. A pruning component 4 for pruning branches is also provided at the top of the pruning rod 3.

[0019] Therefore, when performing shearing operations at different heights, operators can adjust the overall length of the device by increasing the number of extension rods 2 to adapt to shearing operations at different heights. At the same time, by setting up detachable connecting rods 1, extension rods 2 and pruning rods 3, the device can be quickly disassembled and stored after use, making it convenient for operators to carry and transport the device.

[0020] Specifically, such as Figures 4-6As shown, in order to achieve precise positioning of the pruning position, the pruning assembly 4 of this utility model includes a fixed pruning blade 42 fixedly connected to the top of the pruning rod 3. A rotating pruning blade 41 is rotatably connected to the fixed pruning blade 42 via a first rotating shaft 43. A clearance groove 44 is provided at the bottom of the rotating pruning blade 41. The pruning assembly 4 also includes a mounting plate 46 fixedly connected to the inner wall of the pruning rod 3. An electric push rod 47 is provided on the mounting plate 46. A drive rod 45 is fixedly connected to the output end of the electric push rod 47 via a connecting block 48. A sliding rod 49 with one end passing through the clearance groove 44 is fixedly connected to the top of the drive rod 45. The positioning assembly 5 includes a first threaded rod 5 2. A fixing block 51 is threadedly connected to the threaded sleeve 31. A sliding limit groove 53 is provided on the surface of the fixing block 51. A bidirectional lead screw 54 is rotatably connected in the sliding limit groove 53. A servo motor 55 with its output end fixedly connected to one end of the bidirectional lead screw 54 is also provided at one end of the fixing block 51. Two L-shaped rods 56 are threadedly sleeved on the outside of the bidirectional lead screw 54. An arc-shaped positioning plate 57 is fixedly connected to the top of the L-shaped rods 56. The support assembly 6 includes a fixing plate 62 threadedly connected to the threaded sleeve 31 through a second threaded rod 61. An arc-shaped support plate 63 is fixedly connected to the top of the fixing plate 62. Anti-slip rubber sheets are provided on the surfaces of the arc-shaped positioning plate 57 and the arc-shaped support plate 63.

[0021] Therefore, in actual use, the operator controls the fixed plate 62 and the arc-shaped support plate 63 to move under the branch to be pruned by gripping the handle 13, the extension rod 2, and the pruning rod 3. Then, the operator adjusts the positions of the arc-shaped support plate 63, the pruning assembly, and the positioning assembly 5 to the pruning position. The arc-shaped support plate 63 is then pressed against the branch for initial positioning. The operator then activates the servo motor 55 to rotate the bidirectional lead screw 54. The rotation of the bidirectional lead screw 54 causes the two L-shaped rods 56 to move in opposite directions, thereby moving the two arc-shaped support plates 63 and clamping and fixing the branch. At this point, the pruning positioning is completed, avoiding the need for manual intervention. When the operator holds the equipment, the shaking caused by arm fatigue and external interference can lead to a shift in the cutting position. The operator then presses the button on the control lever 12 to activate the electric push rod 47. The electric push rod 47 drives the drive rod 45 to move. The drive rod 45 moves the slide rod 49 to slide in the relief groove 44, and drives the rotating shearing blade 41 to rotate around the first rotating shaft 43 to cut the branches. The fixed mechanism clamps the branches and connects the rod 1, the extension rod 2, and the pruning rod 3 to control the falling direction of the cut branches, preventing them from falling randomly and injuring the operator and the equipment.

[0022] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
