[0002] In fields such as garden maintenance, agricultural operations, and engineering construction, multi-functional robotic arms are frequently required, such as those for mowing, drilling, pruning, and digging. Traditional actuators typically have a single function, requiring specialized equipment for different tasks, resulting in low equipment utilization, cumbersome replacement, and high costs. Furthermore, existing robotic arms have limited range of motion and flexibility, making them unsuitable for complex terrain or multi-angle operations. Instability in support or low power transmission efficiency can also affect work accuracy and safety during operation. Therefore, there is an urgent need for a multi-functional long-arm actuator combination mechanism that allows for flexible replacement of actuators, multi-dimensional motion adjustment capabilities, and stable and reliable operation to improve work efficiency and reduce operating costs.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort in accordance with the embodiments of the basic utility model are within the scope of protection of this utility model.

[0040] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A multifunctional long-arm hydraulic actuator includes a load-bearing mechanism, which serves as the basic support for the entire device. A swing seat 8, an oil supply mechanism, and a tilting mechanism are mounted on the swing seat 8. The swing seat 8 is rotatably mounted at the front end of the load-bearing mechanism and plays a key role in connecting and transmitting power. The tilting mechanism is connected to the swing seat 8 and drives the swing seat 8 to rotate left and right by providing power, thereby changing the working direction of the entire actuator 1 and meeting the working needs of different positions.

[0041] The actuator 1 is detachably mounted on the rotating connecting seat 10, which allows the combined mechanism to flexibly replace the actuator 1 according to different work tasks. The actuator 1 has various types to adapt to different working scenarios.

[0042] The upper arm 5 is rotatably connected at its lower end to the lower part of the swing base 8 and at its upper end to the upper end of the forearm 4. The lower end of the forearm 4 is rotatably connected to the rotating connecting seat 10. This connection method creates a flexible robotic arm structure. A large hydraulic cylinder 6 is rotatably connected between the rear side of the upper arm 5 and the upper part of the swing base 8. The large hydraulic cylinder 6 drives the upper arm 5 to rotate around the rotation connection point between the upper arm 5 and the swing base 8, thereby adjusting the extension angle of the upper arm 5 and realizing the adjustment of the working range at different heights and distances. A small hydraulic cylinder 3 is rotatably connected between the middle front side of the upper arm 5 and the rear side of the forearm 4. The small hydraulic cylinder 3 drives the forearm 4 to rotate, further precisely adjusting the position and angle of the actuator 1 at the front end of the robotic arm and improving the accuracy of the operation.

[0043] The working cylinder 2 has one end rotatably connected to the front side of the forearm 4 and the other end rotatably connected to the second rotating arm 11 and the rotating connecting seat 10 in sequence. The working cylinder 2 drives the actuator 1 to rotate through the second rotating arm 11, so that the actuator 1 can work at different angles and adapt to various complex working environments and operation requirements.

[0044] The first rotating arm 9 has one end rotatably connected to the forearm 4 and the other end coaxially connected to the connection between the working cylinder 2 and the second rotating arm 11, so that the three rotate around the same axis. It plays a role in force transmission and motion coordination between the working cylinder 2 and the rotating connecting seat 10, ensuring that the power of the working cylinder 2 can be effectively transmitted to the rotating connecting seat 10, thereby driving the actuator 1 to run smoothly.

[0045] The oil supply mechanism is connected to the large oil cylinder 6, the small oil cylinder 3 and the working oil cylinder 2 respectively. Its main function is to supply hydraulic power oil to these oil cylinders. By providing stable hydraulic power, it ensures that each oil cylinder can work normally and drive the corresponding components to move, so that the entire multi-functional long-arm actuator can operate efficiently and stably.

[0046] In this embodiment, the oscillation mechanism is preferably an oscillation cylinder 7.

[0047] In this embodiment, reference Figure 6 , Figure 7 and Figure 8The actuator 1 is a mowing mechanism, which includes a cover 1203, a blade shaft 1202, a roller 1201, and a mowing motor 1205. The cover 1203 protects the internal components and prevents debris from splashing during mowing. The roller 1201 and the blade shaft 1202 are rotatably mounted inside the cover 1203, and the mowing motor 1205 is mounted outside the cover 1203. The output end of the mowing motor 1205 is coaxially connected to the blade shaft 1202. When the mowing motor 1205 is started, it drives the blade shaft 1202 to rotate at high speed. The Y-shaped blade 1204, which is circumferentially detachable from the blade shaft 1202, rotates accordingly. The high-speed rotating Y-shaped blade 1204 cuts the grass to achieve the mowing function.

[0048] In this embodiment, reference Figure 9 The actuator 1 is a drilling mechanism, which includes a drilling bracket 1105 and a gearbox 1102 mounted on the drilling bracket 1105. The gearbox 1102 has a drilling motor 1104 on its upper part and a drilling drill bit 1103 connected to its lower part. After the drilling motor 1104 is started, the power is transmitted to the drilling drill bit 1103 through the gearbox 1102, driving the drilling drill bit 1103 to rotate, thereby performing drilling operations on the ground or other working objects. The drilling bracket 1105 is connected to the drilling seat 1101, and the drilling seat 1101 is mounted on the rotating connecting seat 10.

[0049] In this embodiment, reference Figure 10 , Figure 11 and Figure 12The actuator 1 is a pruning mechanism, which includes an extension arm 1307, a bearing seat 1311, a frame plate 1303, and a blade mounting bracket 1302. A pruning motor 1306 mounted on the bearing seat 1311 provides power for the entire pruning action. The output end of the pruning motor 1306 is connected to an eccentric wheel 1312. Multiple blades 1304 are radially detachably mounted on the blade mounting bracket 1302. The extension arm 1307 is connected to the frame plate 1303 via the bearing seat 1311. Multiple pressure plates 1301 are arranged side-by-side on the upper side of the frame plate 1303, and multiple comb teeth 1305 corresponding to the blades 1304 are arranged radially side-by-side on the lower side. A blade mounting bracket is positioned between the pressure plates 1301 and the comb teeth 1305. A mounting bracket 1302 is used to hold the blade 1304 within the opening formed on the comb teeth 1305. The handle moves radially along the comb teeth 1305, causing the comb teeth 1305 and the blade 1304 to move out of alignment, thus pruning the branches. A hinge seat 1308 on the blade mounting bracket 1302 is rotatably connected to a rotating arm 1309. The rotating arm 1309 is connected to a connecting rod 1310. The end of the connecting rod 1310 is rotatably connected to a handle on an eccentric wheel 1312. When the pruning motor 1306 drives the eccentric wheel 1312 to rotate, the handle on the eccentric wheel 1312 drives the blade mounting bracket 1302 to reciprocate through the connecting rod 1310, causing the comb teeth 1305 and the blade 1304 to move out of alignment, thus pruning the branches.

[0050] In this embodiment, reference Figure 13 The actuator 1 is a bucket mechanism, which includes a bucket base 1401 and a bucket body 1402. At least two digging teeth 1403 are detachably provided on the bucket body 1402.

[0051] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
