[0016] Please refer to the following: Figure 1 and Figure 2In one embodiment of this application, a logging device 100 is provided. The logging device 100 includes a frame 20, a clamping mechanism 30 connected to the frame 20, and a felling mechanism 40. The frame 20 is a supporting structure of the logging device 100, used to support the clamping mechanism 30 and the felling mechanism 40. The clamping mechanism 30 is used to clamp the target 10 to be felled, so that during the felling process, it is not necessary to manually hold the target 10. The felling mechanism 40 is used to fell the target 10. In one embodiment, the target 10 to be felled can be bamboo or wood.

[0017] The clamping mechanism 30 includes an airbag 31 and pneumatic components (not shown). The pneumatic components are used to supply or deflate the airbag 31, which is used to clamp the target 10 to be felled when inflated. Typically, the surface of the target 10, such as bamboo or wood, is uneven. During inflation, the airbag 31 can gradually and completely conform to the surface of the target 10, improving the stability of the clamping mechanism 30 when clamping the bamboo or wood.

[0018] When it is necessary to cut down the target 10, the target 10 is first placed in the airbag 31. Then, the pneumatic components inflate the airbag 31. By adjusting the air pressure of the airbag 31, the inflation amount is changed to clamp the target 10 of different thicknesses. Finally, the cutting mechanism 40 starts to operate and begins to saw the target 10.

[0019] In the aforementioned logging device 100, by setting up a clamping mechanism 30, the pneumatic components control the airbag 31 to inflate, so that the airbag 31 clamps the target to be cut 10 in the inflated state, thereby improving the stability of the target to be cut 10 during the logging process, thereby reducing the risk that the logging position of the target to be cut 10 will be unstable due to the inability to hold it tightly during the logging process, and improving the efficiency of the logging mechanism 40 in cutting the target to be cut 10.

[0020] Please continue reading. Figure 1 and Figure 2 In one embodiment, the frame 20 includes a frame 21 and support legs 22 supporting the frame 21, and a clamping mechanism 30 is mounted on the frame 21. The frame 20 serves as the support base for the entire logging device 100, and the frame 21 and support legs 22 can be made of high-strength materials to ensure the overall stability and durability of the logging device 100.

[0021] Please continue reading. Figure 1 and Figure 2In one embodiment, the end of the support foot 22 away from the frame 21 is a pointed structure, which makes it easy to insert and pull out the support foot 22 when fixing the position of the logging device 100. The pointed structure can be more easily inserted into soft ground, such as soil, sand or snow, or find a more stable foothold on irregular terrain, thereby providing better grip and flexibility for the logging device 100 and effectively reducing the shaking and tipping of the logging device 100 during the felling process.

[0022] Please refer to the following: Figure 2 and Figure 3 In one embodiment, the support foot 22 can be designed as a telescopic structure, that is, the support foot 22 includes a first support portion 221 and a second support portion 222. One end of the first support portion 221 is fixedly connected to the frame 21, and the other end of the first support portion 221 is movably connected to the second support portion 222, and the second support portion 222 is telescopic. The end of the second support portion 222 furthest from the first support portion 221 is a pointed structure. The telescopic structure of the support foot 22 can be used to adjust the height of the clamping mechanism 30 and the felling mechanism 40, so that the clamping mechanism 30 can clamp bamboo and wood of different heights, and the felling mechanism 40 can fell bamboo and wood of different heights, thereby improving the versatility of the logging device 100.

[0023] In one embodiment, the telescopic structure between the first support portion 221 and the second support portion 222 can be a threaded adjustment method. The interior of the second support portion 222 may have one or more internal threaded areas, and the exterior of the first support portion 221 may have one or more corresponding external threaded areas. Telescopic adjustment is achieved by rotating the second support portion 222 relative to the first support portion 221. A handle or knob can be provided on the second support portion 222 to serve as a fulcrum for rotation, allowing the internal thread of the second support portion 222 to move along the external thread of the first support portion 221.

[0024] In another embodiment, the telescopic structure between the first support portion 221 and the second support portion 222 can be a button-locking mechanism. The second support portion 222 can be equipped with a spring-loaded button or latch. Pressing the button unlocks the telescopic function, and releasing the button after adjusting to the desired position automatically locks it, thus realizing the telescopic function between the first support portion 221 and the second support portion 222.

[0025] In another embodiment, the telescopic structure between the first support portion 221 and the second support portion 222 can be a slide rail locking method. For example, a slide rail is provided on the outer wall of the first support portion 221, and the second support portion 222 can smoothly extend and retract on the slide rail. At the same time, a locking screw or a buckle is provided on the second support portion 222, and the position of the second support portion 222 is fixed by tightening the screw or pressing the buckle.

[0026] In other embodiments, the telescopic structure between the first support portion 221 and the second support portion 222 can also be configured as a hydraulic telescopic mechanism or an electric telescopic mechanism.

[0027] Please refer to the following: Figure 1 and Figure 4 In one embodiment, there are two airbags 31, namely a first airbag 311 and a second airbag 312. The first airbag 311 and the second airbag 312 are arranged at a distance from each other to form a receiving space 313 for accommodating the target 10 to be cut. In the inflated state, the first airbag 311 and the second airbag 312 squeeze the target 10 to be cut from both sides, thereby holding the target 10 tightly. The dual airbag design can quickly surround and lock the target 10 to be cut in a short time. By applying pressure to both sides of the target 10 to be cut, the target 10 to be cut is effectively fixed, reducing unnecessary movement or swinging of the target 10 during the cutting process, and improving the stability and safety of the cutting.

[0028] Please refer to the following: Figure 1 and Figure 5 In another embodiment, there is one airbag 31. The airbag 31 is semi-circular to form a semi-enclosed space 313 for accommodating the target to be felled 10. When inflated, the semi-circular airbag 31 can hold the target to be felled 10 tightly. The pressure of the evenly distributed airbag 31 provides stable support, reducing the risk of the target to be felled 10 shaking or suddenly falling during the felling process, and improving the safety and controllability of the logging process.

[0029] Please refer to it again. Figure 1 and Figure 4 In one embodiment, the airbag 31 is an arc-shaped airbag 31 when inflated. The arc-shaped airbag 31 can better adapt to the target 10 to be cut down in different shapes and sizes. Its arc design can provide uniform contact and wrapping for the target 10 to be cut down, thereby improving the effect of fixing or supporting the target 10 to be cut down.

[0030] In one embodiment, the material of the airbag 31 includes at least one of rubber and silicone.

[0031] Please continue reading. Figure 1 and Figure 4 In one embodiment, each airbag 31 may include multiple interconnected airbag portions 314, and pneumatic components are used to supply and deflate the multiple first airbag portions 311. The multiple interconnected airbag portions 314 can cooperate together when inflated to form a continuous and uniform covering layer that surrounds and holds the target 10 to be cut down. This helps to evenly distribute pressure across the entire contact surface, reduce local stress concentration, avoid damage to the target 10 to be cut down, and improve the clamping effect of the airbag 31.

[0032] Please continue reading. Figure 1 and Figure 4 In one embodiment, the airbag 31 further includes multiple switching valves and multiple pressure sensors. The multiple switching valves are connected to multiple airbag sections 314 in a one-to-one correspondence to control the air intake and exhaust of each airbag section 314. The multiple pressure sensors are connected to multiple airbag sections 314 in a one-to-one correspondence to sense the air pressure of each airbag section 314. Each airbag section 314 is equipped with an independent switching valve and pressure sensor, which can precisely control the inflation volume and internal air pressure of each airbag section 314. This allows the clamping mechanism 30 to adjust the inflation volume of each airbag section 314 according to the diameter and surface morphology of the target 10 when clamping it, flexibly adapting to various clamping requirements to ensure that the target 10 is uniformly and securely fixed.

[0033] During actual clamping, if an abnormal pressure (too high or too low) is detected in a certain airbag section 314, the corresponding pressure sensor will immediately provide feedback. The control system will then quickly adjust the working state of the corresponding switch valve to replenish or release gas, thereby restoring the set optimal air pressure value and improving the safety and efficiency of the clamping process.

[0034] In one embodiment, the airbag 31 in the clamping mechanism 30 can also achieve the function of adaptive contraction through other hydraulic methods such as water pressure or oil pressure.

[0035] Please continue reading. Figure 1 and Figure 4 In one embodiment, the clamping mechanism 30 further includes a base 32 and connecting arm assemblies 33. The base 32 is mounted on the frame 21 of the frame 20. There are two connecting arm assemblies 33: a first connecting arm assembly 331 and a second connecting arm assembly 332. Both the first connecting arm assembly 331 and the second connecting arm assembly 332 are connected to the base 32. The first connecting arm assembly 331 is connected to the first airbag 311, and the second connecting arm assembly 332 is connected to the second airbag 312. This design with two connecting arm assemblies 33 allows the first airbag 311 and the second airbag 312 to simultaneously apply balanced pressure to the target 10 from both sides, reducing the risk of slippage during clamping and improving the gripping effect.

[0036] Please continue reading. Figure 1 and Figure 4In one embodiment, the first connecting arm assembly 331 and the second connecting arm assembly 332 are rotatably connected to the base 32 so as to adjust the distance between the first connecting arm assembly 331 and the second connecting arm assembly 332, thereby increasing the adjustment space of the clamping mechanism 30. This allows the clamping mechanism 30 to adapt to different sizes, shapes and positions of the target to be felled 10. By adjusting the inflation amount of the first airbag 311 and the second airbag 312, the extension length and clamping force of the first connecting arm assembly 331 and the second connecting arm assembly 332 can be adjusted, thereby improving the clamping force of the clamping mechanism 30 and also improving the versatility of the logging device 100.

[0037] Please continue reading. Figure 1 and Figure 4 In one embodiment, the first connecting arm assembly 331 includes at least one first connecting arm 3311 connected to the first airbag 311, and the second connecting arm assembly 332 includes at least one second connecting arm 3321 connected to the second airbag 312. Both the first connecting arm 3311 and the second connecting arm 3321 are arc-shaped connecting arms, which can fit more closely to the contour of the target 10 to be cut. No matter how the diameter or shape of the target 10 to be cut changes, the first connecting arm 3311 and the second connecting arm 3321 with arc-shaped structure can be adjusted to apply force evenly, thereby achieving a more effective grip and reducing damage to the surface of the target 10 to be cut.

[0038] Please continue reading. Figure 1 and Figure 4 In one embodiment, a clearance space 333 is formed between the first connecting arm 3311 and the second connecting arm 3321, which communicates with the accommodating space 313. This space provides a path for the logging mechanism 40 to enter and exit, thus avoiding tool jamming or work interruption due to insufficient space during the logging process.

[0039] Please continue reading. Figure 1 and Figure 4 In one embodiment, the side of the frame 21 is provided with an avoidance opening 211 that communicates with the avoidance space 333, reducing the risk that the clamping mechanism 30 cannot fully hold the target to be cut due to the side of the frame 21 resisting the target to be cut 10.

[0040] Please continue reading. Figure 1 and Figure 4 In one embodiment, the first airbag 311 and the first connecting arm 3311, and the second airbag 312 and the second connecting arm 3321 are all detachable structures. In the event of damage or leakage of the first airbag 311 or the second airbag 312, only the first airbag 311 or the second airbag 312 needs to be replaced, thereby reducing maintenance costs and improving the long-term efficiency of the logging device 100.

[0041] Please see Figure 1 In one embodiment, the logging device 100 further includes a reinforcing member 50, one end of which is connected to the frame 20, and the other end of which is connected to the base 32. The reinforcing member 50 improves the stability and rigidity of the entire logging device 100, effectively reducing deformation between the frame 20 and the base 32. During logging, the reinforcing member 50 can effectively disperse the stress generated by the felling mechanism 40, preventing overload on parts of the frame 20 and the base 32, thereby extending the lifespan of the logging device 100.

[0042] Please see Figure 2 In one embodiment, the felling mechanism 40 includes a drive member 41 and an electric saw 42. The drive member 41 is connected to the frame 20, and drives the electric saw 42 to move, thereby causing the electric saw 42 to fell the target 10. The drive member 41 is directly connected to the electric saw 42, and drives the electric saw 42 to rotate at high speed by electricity, thereby improving felling efficiency.

[0043] Please continue reading. Figure 2 In one embodiment, the felling mechanism 40 further includes a guide member 43, the extension direction of which is the same as the extension direction of the output shaft of the drive member 41. The guide member 43 is slidably connected to the frame 20, and the chainsaw 42 is connected to the guide member 43. Under the drive of the drive member 41, the chainsaw 42 and the guide member 43 move synchronously in the extension direction of the guide member 43. The connection between the guide member 43 and the chainsaw 42 ensures that the chainsaw 42 moves along the extension direction of the guide member 43 during felling, reducing the risk of disordered cutting caused by the chainsaw 42 deviating from its movement trajectory under the drive of the drive member 41, and improving the accuracy of felling.

[0044] Please refer to the following: Figure 2 and Figure 6 In one embodiment, the guide member 43 includes a guide rail 431 and a guide slider 432. The guide rail 431 is connected to the frame 20, and the guide slider 432 is slidably connected to the guide rail 431. The chainsaw 42 is connected to the side of the guide slider 432 opposite to the guide rail 431. When the drive member 41 drives the chainsaw 42 to move, the chainsaw 42 causes the guide slider 432 to slide relative to the guide rail 431, improving the stability of the chainsaw 42 during the logging process.

[0045] Please continue reading. Figure 2 and Figure 6 In one embodiment, the felling mechanism 40 further includes two stops 44, which are spaced apart at both ends of the guide rail 431 along the extension direction of the guide member 43. The stops 44 are used to reduce the risk of the guide slider 432 disengaging from the guide rail 431 when it slides on the guide rail 431.

[0046] Understandably, the surface of the two stops 44 on opposite sides can be covered by the buffer 45, which plays a buffering role when the guide slider 432 impacts the stop 44, thereby improving the service life of the guide 43.

[0047] Please continue reading. Figure 2 and Figure 6 In one embodiment, there are two guide members 43, spaced apart, with the chainsaw 42 connected to both guide members 43 simultaneously. Driven by the drive member 41, the chainsaw 42 moves synchronously with the two guide members 43 in the extending direction of the guide members 43. The spacing between the two guide members 43 provides dual guidance and support for the chainsaw 42, ensuring more stable linear movement of the chainsaw 42 during felling, reducing chainsaw deviation and vibration, thereby improving felling accuracy.

[0048] Please refer to the following: Figure 1 , Figure 2 and Figure 4 The process of the logging device 100 cutting down the target 10 to be logged includes the following:

[0049] First, the target to be felled, such as bamboo or trees, is placed between the first airbag 311 and the second airbag 312 of the clamping mechanism 30, and the support foot 22 with a pointed structure is fixed to the ground to fix the entire frame 20.

[0050] Next, the logging device 100 is powered on, causing the pneumatic components to inflate the first airbag 311 and the second airbag 312. By adjusting the air pressure of the first airbag 311 and the second airbag 312, the inflation amount of the first airbag 311 and the second airbag 312 is changed, so as to clamp bamboo and wood of different thicknesses.

[0051] Next, after the first airbag 311 and the second airbag 312 clamp the target 10 to be cut, the operator retreats to a safe area, the cutting mechanism 40 starts to operate, and the drive component 41 drives the electric saw 42 to move slowly forward to cut the target 10 to be cut.

[0052] Finally, after the sawing is completed, the electric saw 42 stops operating, and the pneumatic components depress the first airbag 311 and the second airbag 312, causing the first airbag 311 and the second airbag 312 to contract, thereby opening the first airbag 311 and the second airbag 312 to lay down the target 10 to be cut down, and the sawing work is completed.

[0053] The above are merely embodiments of this application and do not limit the scope of this patent application. Any equivalent structural or procedural changes made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
