[0002] Southwest my country is an important distribution area for bamboo resources, with extremely rich bamboo resources. However, traditional equipment used in bamboo harvesting operations suffers from numerous problems, severely impacting harvesting efficiency. Firstly, the insufficient power cord length of traditional equipment limits the operating range, making localized harvesting difficult. Secondly, equipment relocation is extremely inconvenient, especially in areas with complex terrain and uneven bamboo distribution, where equipment cannot be flexibly moved to bamboo forests far from power sources. Furthermore, the short power cords of harvesting equipment further restrict the range of movement and increase the difficulty of relocation. To complete harvesting tasks, it is often necessary to frequently move harvesting and transport equipment, and to frequently plug and unplug power cords and reconnect them. These problems not only increase the input of manpower and resources but also increase the complexity of operations. More seriously, these problems lead to a reduction in the amount of bamboo harvested per unit time and a longer harvesting cycle, thus reducing the overall efficiency of bamboo harvesting operations.

Detailed Implementation

[0023] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] In the description of this utility model, it should be understood that the terms "longitudinal," "radial," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] like Figures 1 to 7 As shown, one embodiment of this utility model provides a winding mechanism for a bamboo-cutting shears power cord, including a mounting frame 1, a winding assembly 2, a cable laying assembly 3, and a locking assembly 4 mounted on the mounting frame 1. The winding assembly 2 and the cable laying assembly 3 are sequentially mounted on the mounting frame 1 along the axial direction of the mounting frame 1. The winding assembly 2 includes a winding limit member 21. The locking assembly 4 controls the rotation state of the winding limit member 21 through mechanical limiting, thereby switching between the locked and unlocked states of the winding mechanism. The winding assembly 2 is used to wind the bamboo-cutting shears power cord, and the bamboo-cutting shears power cord wound on the winding assembly 2 passes through the cable laying assembly 3 to prevent tangling. When the locking assembly 4 controls the winding limit member 21 to be in a stationary state through mechanical limiting, the winding mechanism is in the locked state; conversely, the winding mechanism is in the unlocked state.

[0027] This invention achieves efficient, safe, and convenient power cord management through its unique structural design. The winding assembly 2 is used to wind the power cord of the bamboo felling shears, ensuring the orderly use and storage of the power cord. The cable routing assembly 3 effectively prevents the power cord from tangling and knotting during winding, thereby improving the safety and reliability of the operation. The locking assembly 4 controls the rotation state of the winding limiter 21 through mechanical limit control, realizing the locking and unlocking functions of the winding mechanism. In the locked state, the winding mechanism remains stationary, ensuring the stability and reliability of the equipment during transportation or when not in operation; while in the unlocked state, the winding assembly 2 can rotate freely, facilitating the rapid winding and unwinding of the power cord, improving operational efficiency. Furthermore, this winding mechanism is compact, lightweight, portable, and flexible in installation. It can be installed on forestry machinery or carried manually, making it particularly suitable for forestry operations in complex terrains such as hilly and mountainous areas. Overall, the winding mechanism effectively extends the range of power cord usage, reduces the frequency of equipment handling, and enhances the applicability and practicality of electric bamboo felling shears in forestry operations, providing a more efficient, safe, and convenient solution for forestry operations.

[0028] In one embodiment, such as Figure 2 As shown, the winding limiter 21 includes a first baffle 211 and a second baffle 212; the winding assembly 2 also includes at least two winding tubes 22 connected between the first baffle 211 and the second baffle 212, a first connecting tube 23 connecting the first baffle 211 away from the end face of the winding tube 22, a second connecting tube 24 connecting the second baffle 212 away from the end face of the winding tube 22, and a handle 25 coaxially arranged with the second connecting tube 24. Understandably, the number of winding tubes 22 can be set according to requirements. The winding tubes 22 are used to wind the power cord of the bamboo felling shears, ensuring the orderliness of the power cord during use and storage, avoiding messiness and tangling, thereby improving the safety and reliability of the operation. The installation methods between the winding tubes 22 and the first baffle 211 and the second baffle 212 include, but are not limited to, fixed connection, plug-in, and snap-fit. The first connecting tube 23 and the second connecting tube 24 are coaxially arranged, and the first baffle 211 and the second baffle 212 are connected to both ends of the winding tube 22, forming a closed limiting frame. This prevents the power cord from shifting and protects the cord by evenly distributing the winding tension. The handle 25, coaxially arranged with the second connecting tube 24, provides the operator with a convenient rotation operation method. When the operator turns the handle 25, the winding assembly 2 rotates accordingly, thereby realizing the rapid winding and unwinding of the power cord.

[0029] In one embodiment, such as Figures 2 to 3As shown, both the first baffle 211 and the second baffle 212 are provided with mounting holes 26 and locking holes 27. Understandably, the mounting holes 26 adopt a symmetrically distributed through-hole design, and the winding tube 22 is axially fixed between the first baffle 211 and the second baffle 212 by bolts or pins for mounting the winding tube 2. The locking holes 27 are used for dynamic linkage connection with the locking assembly 4. Through the cooperation of the limiting component in the locking assembly 4 with the locking holes 27, the rotation state of the winding limit member 21 can be precisely controlled. When the limiting component of the locking assembly is inserted into the locking hole 27, the winding limit member 21 is fixed, and the winding assembly 2 is in a stationary state. The number and arrangement of the mounting holes 26 and locking holes 27 can be set according to requirements. Specifically, a multi-number layout of the locking holes 27 can provide multiple locking positions to meet the fixing requirements of different scenarios.

[0030] In one embodiment, such as Figure 4 As shown, the mounting frame 1 includes a frame 13 formed by connecting a horizontal plate 11 and a vertical plate 12, reinforcing plates 14 installed on opposite sides of the frame 13, and a mounting base 15 for mounting bearings 5 ​​installed at the top of the horizontal plate 11; the first connecting pipe 23 and the second connecting pipe 24 are respectively connected to one of the bearings 5. Understandably, the mounting base 15 is installed at the top of the horizontal plate 11 to fix the bearings 5, so that the rotating part of the winding assembly 2 can be precisely positioned and supported. The first connecting pipe 23 and the second connecting pipe 24 are respectively interference-fitted with the bearings 5. This fit ensures a tight connection between the two connecting pipes and the bearings 5, thereby ensuring the stability and reliability of the winding assembly 2 during rotation.

[0031] In one embodiment, such as Figures 5 to 7As shown, the locking assembly 4 includes a locking plate 41 with a U-shaped groove 411, a locking seat 42, and a locking pin 43. The locking seat 42 has a first insertion hole 421 and a second insertion hole. The locking pin 43 includes an operating part 431 and a mounting part 432 connected to the operating part 431. A nut 44 and a spring 45 are threaded onto the mounting part 432. The spring 45 is sleeved on the locking pin 43 and abuts against the nut 44 and the second insertion hole (not shown). The locking plate 41 is connected to the side wall of the horizontal plate 11, and the top end of the locking seat 42 is connected to the bottom wall of the horizontal plate 11. Understandably, the locking assembly 4, through the coordinated action of the locking plate 41, the locking seat 42, and the locking pin 43, achieves the locking and unlocking functions of the winding limiter 21. The U-shaped groove 411 on the locking plate 41 provides a limiting and guiding function for the locking pin 43, ensuring that it can accurately insert into or withdraw from the locking hole 27 during operation, thereby fixing or releasing the cable reel assembly 2. The first and second insertion holes on the locking seat 42 provide space for the installation and movement of the locking pin 43, while the combination of the nut 44 and the spring 45 provides elastic support for the locking pin 43, allowing it to extend and retract smoothly during operation and maintain a certain preload under the action of the spring, enhancing the reliability of the locking. This design not only effectively prevents the cable reel assembly 2 from accidentally rotating during transportation or in a non-working state, avoiding the power cord from becoming loose or tangled, but also allows for quick unlocking when needed, facilitating the winding and unwinding of the power cord.

[0032] In one embodiment, such as Figure 1 As shown, the cable assembly 3 includes a first cable mounting side plate 31, a second cable mounting side plate 32, and a plurality of limiting tubes 33 connecting the first cable mounting side plate 31 and the second cable mounting side plate 32; the first cable mounting side plate 31 and the second cable mounting side plate 32 are respectively fixedly mounted on the vertical plates 12 on opposite sides of the frame 13. Understandably, the cable assembly 3 consists of the first cable mounting side plate 31, the second cable mounting side plate 32, and a plurality of limiting tubes 33 connecting the two. This design physically restricts the movement range of the power cord, ensuring that the power cord can only move up and down between the limiting tubes 33, while the left and right movement range is limited between the first cable mounting side plate 31 and the second cable mounting side plate 32. This dual restriction mechanism allows the power cord to be evenly distributed on the winding tube 22 during winding, avoiding tangling problems caused by messy power cords, thereby improving the service life and safety of the power cord.

[0033] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
