In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0028] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0029] like Figures 1 to 6As shown, an embodiment of the present invention provides an extended-range forest multifunctional power work platform, including a work platform 1, wherein the work platform 1 includes a bottom frame 11 and an upper frame 12 connected to the top of the bottom frame 11, and the bottom of the bottom frame 11 is connected to a transport mechanism 2; it also includes a travel drive 3 and a range-extending component 4 sequentially installed on the bottom frame 11 for driving the transport mechanism 2; the travel drive 3 is located at the starting end of the work path direction of the work platform 1; the side of the upper frame 12 is flipped to connect the branch picking mechanism 5, and the branch picking mechanism 5 is arranged opposite to the travel drive 3, and the bottom end of the branch picking mechanism 5 is connected to the support extension platform 6; when the branch picking mechanism 5 completes the branch picking operation, the branch picking mechanism 5 flips to the support extension platform 6 and the upper frame 12 to be on the same horizontal plane. Among them, the front refers to the front of the work path direction, the rear refers to the rear of the work path direction, and the top refers to Figure 1 The upper part of the vertical workbench 1 and the lower part refer to Figure 1 Below the vertical working platform 1. The travel drive 3 and the range extension component 4 are both arranged on the bottom frame 11 and arranged opposite to each other. The pruning mechanism 5 is installed on the side of the upper frame 12 and is on the same side as the range extension component 4. The range extension component 4 can be detachably installed on the bottom frame 11 and is used to extend the battery life by charging the battery system of the device without the need for frequent charging or battery replacement. The travel drive 3 is used to drive the transportation mechanism 2 to drive the working platform 1 and the entire harvesting and transportation composite operation device. It can be understood that the pruning mechanism 5 is used for felling operations. After completing the felling operation, the pruning mechanism 5 can be turned 180° on the side of the upper frame 12, turned so that the pruning mechanism 5 faces the ground and the support extension platform 6 faces away from the ground. At this time, the support extension platform 6 and the upper frame 12 are almost in the same horizontal plane. In this way, the transportation platform on the upper frame 12 for transporting bamboo is extended to ensure the stability of the transportation of very long bamboo.

[0030] In the present invention, the device achieves efficient integration of felling and transportation functions and improved endurance through modular structural design: the layered frame structure of the work platform 1 provides a reasonable layout space for functional components, the front-end walking drive 3 directly drives the transportation mechanism 2, ensuring that the device can move stably in complex terrain, and the rear-end extended-range component 4 flexibly supplements power through a detachable installation method, solving the problem of insufficient endurance of traditional electric equipment; the branch picking mechanism 5 on the side of the upper frame 12 has a 180° flip function, which undertakes the task of felling and picking branches during operation. After completion, it flips to the support extension platform 6 to be coplanar with the upper frame 12, seamlessly extending the originally independent transportation platform, which not only meets the stability requirements of long bamboo transportation, but also avoids the space occupied by additional transportation devices through space reuse. It not only realizes on-site processing of bamboo, but also can quickly switch to transportation mode after felling, expands the transportation platform area, enhances stability when transporting long bamboo, reduces the risk of shaking or falling due to excessive length of bamboo, and improves the overall safety and efficiency of the operation. The entire system improves forestry operation efficiency while taking into account endurance and transportation reliability through power layout optimization, functional component linkage and structural adaptive adjustment.

[0031] In one embodiment, if Figure 1 、 Figure 3 、 Figure 4 and Figure 6 As shown, the number of the transport mechanisms 2 and the number of the travel drive members 3 corresponds one-to-one, and both are set to two. The transport mechanism 2 includes a travel track 21, a drive wheel 22, a supporting roller 23, and a track roller 24. The drive wheel 22 is engaged with the internal teeth of the travel track 21; the drive wheel 22 is connected to the travel drive member 3. It is understandable that the number of transport mechanisms 2 of this extended-range forestry multi-functional power work platform can be set according to demand. Specifically, two can be symmetrically arranged below the bottom frame 11; that is, two travel tracks 21 are provided below the bottom frame 11, and each travel track 21 is equipped with corresponding drive wheels 22, supporting rollers 23, and track rollers 24, as well as a travel drive member 3. The two symmetrically arranged tracks 21 evenly distribute the device's weight, reducing ground pressure and enhancing grip and stability in complex terrain. This design effectively prevents the device from tipping over or sliding, particularly in hilly and mountainous terrain. The drive wheels 22 mesh with the tracks 21 to provide strong traction, the track rollers 23 evenly bear the weight and cushion bumps, and the support rollers 24 maintain the tension of the tracks 21. Together, these three ensure driving stability. This transport mechanism 2 and frame design enhance the platform's terrain maneuverability, enabling stable operation in rugged mountainous environments.

[0032] In one embodiment, if Figures 1 to 7As shown, the travel drive member 3 includes a drive motor 31, a first reducer 33 and a support bearing 32. The drive motor 31 and the first reducer 33 are both mounted on the end of the upper frame 12 away from the branch picking mechanism 5 through a mounting seat 7. It can be understood that the output shaft of the drive motor 31 is connected to the first reducer 33, and one side of the first reducer 33 is connected to a group (two) of the support bearings 32. In this way, the two symmetrically arranged travel shoes are respectively connected to a drive member, and the two drive motors 31 are each connected and installed using two support bearings 32 to carry a larger torque and improve the machine's ability to pass on slopes. In addition, this structure achieves efficient power transmission and improved stability under complex terrain through the coordinated optimization of the split drive layout and the rigid support design: the support bearings 32 disperse the torque of the drive motor 31, and combined with the differential control of the symmetrical dual-drive system, it effectively copes with the risks of slipping on steep slopes and vehicle overturning.

[0033] In one embodiment, if Figure 3 So and Figure 5 The extended-range forestry multifunctional power work platform also includes a flip assembly 8, through which the pruning mechanism 5 is connected to the side of the upper frame 12. The flip assembly 8 includes a slewing bearing 81, a second reducer 82 connected to the slewing bearing 81, and a rotating shaft 83 connected to the slewing bearing 81. The rotating shaft 83 is fixedly connected to the side wall of the pruning mechanism 5. It is understood that the slewing bearing 81 includes but is not limited to a UCP series bearing. The configuration of the second reducer 82 (which can be an NRV series second reducer 82) can assist in the pruning machine's flipping, improving the convenience of manual operation. The second reducer 82 is a worm gear series second reducer 82 with a self-locking reverse stroke, which can improve the safety of the operation process. It is understood that the pruning mechanism 5 is connected to the flip assembly 8 via the rotating shaft 83. The rotating shaft 83 is connected to the slewing bearing 81, and the slewing bearing 81 is connected to the second reducer 82. When the pruning mechanism 5 needs to be flipped, the operator activates the second reducer 82 by driving the operating components. This in turn rotates the slewing bearing 81, ultimately causing the pruning mechanism 5 to flip around the rotation axis 83. This allows the pruning mechanism 5 to be quickly adjusted to suit different operational needs, enabling it to quickly switch to the optimal operating state, whether for bamboo felling or transportation. This flexibility enables the device to efficiently complete multiple tasks, reducing downtime caused by adjustments, and significantly improving the overall efficiency of forestry operations.

[0034] In one embodiment, if Figure 3As shown, a support seat 9 is provided on the side of the upper frame 12, and the second reducer 82 is mounted on the support seat 9; the flip assembly 8 also includes a handwheel 84 connected to the slewing bearing 81. It is understandable that the driving operating component can use a handwheel 84 to drive the second reducer 82. The support seat 9 provides a rigid mounting base for the second reducer 82, which can be anchored to the side of the upper frame 12 by bolts, providing stable mechanical support and precise positioning for the flip assembly 8; it not only ensures the stability of the second reducer 82 during operation, but also optimizes the spatial layout of the entire flip assembly 8, effectively disperses the concentrated load generated during the flip operation, and avoids local deformation of the workbench 1. As a human-machine interaction component, the handwheel 84 converts the operator's manual rotation action into precise power output for driving the slewing bearing 81 through the low-speed and high-torque amplification characteristics of the worm gear second reducer 82.

[0035] In one embodiment, if Figure 3 So and Figure 5 As shown, the pruning mechanism 5 includes a pruning knife 51, a transport roller 52 and a drive motor 53 connected to the transport roller 52. It is understandable that the number of transport rollers 52 can be set to multiple, and multiple transport rollers 52 can share a drive motor 53 using the solution of the existing technology. When the drive motor 53 rotates, it drives the transport roller 52 to rotate, thereby achieving continuous traction of bamboo or other slender objects. In forestry operations, the application scope of the pruning mechanism 5 is not limited to bamboo, but can also be extended to other slender objects similar to bamboo, such as wood, branches, vines, etc. The pruning knife 51 is located at the front end of the pruning path. When the bamboo or other objects enter the cutting area of the pruning knife 51, the continuous traction force of the transport roller 52 ensures that the objects pass through the pruning knife 51 stably. This design ensures that the side branches are evenly stressed when colliding with the pruning knife 51, which not only effectively removes small branches, but also reduces damage to the main stem, ensuring the integrity of the object. In addition, by adjusting the shape of the pruning knife 51 and the spacing of the transport rollers 52, the pruning mechanism 5 can adapt to objects of different diameters and lengths, further improving its applicability and flexibility in various forestry operation scenarios.

[0036] In one embodiment, if Figure 1 、 Figure 4 and Figure 6As shown, the extended-range forest multifunctional power work platform also includes baffles 121 provided on opposite sides of the upper frame 12, and a plurality of rope rings 122 provided on the peripheral side walls of the upper frame 12. It is understandable that after the felling operation is completed by the pruning mechanism 5, it is flipped 180° to the supporting extension platform 6 to be coplanar with the upper frame 12 to expand the transportation platform area and provide sufficient space for transporting bamboo, wood, etc. At this time, the baffle 121 can be taken out from the accommodating cavity provided in the upper frame 12. The baffle 121 can be installed on the upper frame 12 by a detachable installation method (such as a latch), and the felled bamboo and wood are laterally limited, effectively preventing the bamboo or wood from sliding or overturning due to bumps on the slope, and is particularly suitable for the transportation stability requirements of long materials. The rope ring 122 and the baffle 121 form a dual fixing system of "rigid limitation + flexible binding". The operator can use the rope to anchor the material to the work platform 1 at multiple points in the longitudinal and transverse directions. Even when making sharp turns on steep slopes, the material can be ensured to have almost zero displacement, and the material will not become loose, shake or fall due to vibration, further enhancing the stability of the transportation process.

[0037] In one embodiment, if Figure 1 As shown, the extended-range forestry multifunctional power work platform also includes a power source 10 that is detachably mounted in the middle of the base frame 11, and the range extender assembly 4 that is detachably mounted at the rear of the base frame 11. The range extender assembly 4 is electrically connected to the power source 10 via an electrical circuit. As can be appreciated, by designing the power source 10 and the range extender assembly 4 to be detachably mounted in the middle and rear of the base frame 11, the flexibility and ease of maintenance of the extended-range forestry multifunctional power work platform are significantly improved. Furthermore, the detachable design facilitates separate maintenance and repair of the power source 10 and the range extender assembly 4, reducing equipment downtime and lowering maintenance costs.

[0038] In one embodiment, if Figure 2 As shown, the extended-range forestry multifunctional power work platform also includes a step-down module 123 mounted at the front end of the underlying frame 11. As can be understood, the main function of the step-down module 123 is to reduce the voltage of the power source 10 (such as a battery or a high-voltage power source provided by a range extender) to a voltage level suitable for use by the various components within the device, thereby reducing energy loss during transmission. This voltage conversion not only improves energy utilization efficiency but also reduces energy consumption during system operation, thereby extending the device's battery life.

[0039] The present invention also provides an extended-range forest multifunctional power operation equipment, including the above-mentioned extended-range forest multifunctional power operation platform. In the equipment in the above-mentioned embodiment of the present invention, the extended-range forest multifunctional power operation platform includes an operation platform 1, the operation platform 1 includes a bottom frame 11 and an upper frame 12 connected to the top of the bottom frame 11, and the bottom of the bottom frame 11 is connected to a transport mechanism 2; it also includes a travel drive 3 and an extended-range component 4 for driving the transport mechanism 2, which are sequentially installed on the bottom frame 11; the travel drive 3 is located at the starting end of the operation path direction of the operation platform 1; the side of the upper frame 12 is flipped to connect the branch picking mechanism 5, and the branch picking mechanism 5 is arranged opposite to the travel drive 3, and the bottom end of the branch picking mechanism 5 is connected to the support extension platform 6; when the branch picking mechanism 5 completes the branch picking operation, the branch picking mechanism 5 flips to the support extension platform 6 and the upper frame 12 are located at the same horizontal plane.

[0040] In the equipment of the above-mentioned embodiment of the present invention, the efficiency and adaptability of forestry operations in hilly and mountainous areas are significantly improved through modular structural design and functional integration innovation: its dual-track drive system combined with a split motor layout effectively disperses the load and enhances the passability on complex terrain; the range-extending component 4 and the detachable power supply 10 design solve the bottleneck of electric equipment endurance and support long-term field operations; the 180° flip function of the delimbing mechanism 5 realizes seamless switching between felling and transportation modes, and cooperates with the support extension platform 6 and the baffle 121 rope ring 122 system to ensure the stability of long bamboo transportation and reduce the complexity of the equipment through space reuse.

[0041] The embodiments described above are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
