[0035] like Figures 1 to 6As shown, this embodiment provides a multi-functional cleaning vehicle, which includes a vehicle body 1, a working arm 2, a trimming mechanism 4, and a cleaning mechanism 5. The working arm 2 is rotatably mounted on the vehicle body 1, and a first rotating mechanism 3 is provided at the drive end of the working arm 2. The trimming mechanism 4 includes a trimming connecting seat 41 and a trimming component 42. The trimming component 42 includes a trimming mounting seat 421 and a trimming scissors 422 rotatably mounted on the trimming mounting seat 421. The trimming connecting seat 41 is connected to the trimming mounting seat 421 and is detachably connected to the first rotating mechanism 3. The cleaning mechanism 5 includes a cleaning connecting seat 51 and a cleaning component 52. The cleaning component 52 includes a cleaning mounting seat 521 and a cleaning roller brush 522 rotatably mounted on the cleaning mounting seat 521. The cleaning connecting seat 51 is connected to the cleaning mounting seat 521 and is detachably connected to the first rotating mechanism 3. When roadside green belts need to be trimmed, the trimming mechanism 4 is assembled by connecting it to the first rotary mechanism 3 via the trimming connector 41. The working arm 2 and the first rotary mechanism 3 drive the trimming mechanism 4 to the position to be trimmed and move it according to a preset path. The trimming shears 422 rotate to trim the green belt. When it is necessary to clean the surface waiting to be cleaned, the trimming mechanism 4 is detached and the cleaning mechanism 5 is assembled by connecting it to the first rotary mechanism 3 via the cleaning connector 51. The working arm 2 and the rotary mechanism then drive the trimming mechanism 4 to the position to be cleaned and move it according to a preset path. The cleaning roller brush 522 cleans the surface to be cleaned. This multi-functional cleaning vehicle can perform both trimming and cleaning operations as needed, eliminating the need for separate trimming and cleaning vehicles, effectively improving work efficiency and saving costs.

[0036] Specifically, such as Figures 1 to 4 As shown, the vehicle body 1 includes a front end 11, a platform, and a cargo box 12. The cargo box 12 is mounted on the platform, and the working arm 2 is mounted on the platform and located outside the cargo box 12. Preferably, the platform has a protrusion 13, for example, near the front end 11. The cargo box 12 is located next to the protrusion 13, and the working arm 2 is mounted on the protrusion 13, raising the height of the working arm 2 and preventing interference between the working arm 2 and the cargo box 12. More preferably, guardrails 14 are provided on both sides of the protrusion 13, making it easier for workers to climb onto the protrusion 13 and the top of the cargo box 12 for maintenance and replacement of parts. The guardrails 14 effectively improve safety when climbing. The interior of the cargo box 12 is used to house the power source module, which provides power to the working arm 2, the first rotating mechanism 3, the trimming mechanism 4, and the cleaning mechanism 5. Optionally, the cargo box 12 can also house the disassembled trimming mechanism 4 or the cleaning mechanism 5, facilitating easy switching of the multi-functional cleaning vehicle's operation type and improving operational efficiency and practicality.

[0037] In this embodiment, a telescopic support leg is provided under the vehicle platform. The telescopic support leg can extend to support the ground or retract to leave the ground, thereby improving the stability of the vehicle body 1 during operation. The telescopic support leg can be, but is not limited to, a hydraulic cylinder.

[0038] More specifically, the working arm 2 includes a first arm section 21, a second arm section 22, and a third arm section 23. The first arm section 21 is rotatably mounted on the vehicle body 1, for example, by means of a third slewing mechanism mounted on a boss 13 to achieve rotation around the Z direction, where the Z direction is perpendicular to the ground. One end of the second arm section 22 is hinged to the first arm section 21 around a first axis perpendicular to the Z direction. The third arm section 23 is hinged to the other end of the second arm section 22 around a second axis perpendicular to the Z direction. The first slewing mechanism 3 is located at the end of the third arm section 23 opposite to the second arm section 22. Through the sequential hinged arrangement of the first arm section 21, the second arm section 22, and the third arm section 23, the cleaning mechanism 5 or the trimming mechanism 4 at the end can be flexibly lifted to the work position, and it is not easy for it to interfere with the vehicle body 12 during the lifting process.

[0039] Preferably, such as Figure 5 and Figure 6 As shown, the multi-functional cleaning vehicle also includes a second rotating mechanism 6, which is positioned between the third arm section 23 and the first rotating mechanism 3. The rotation axis of the first rotating mechanism 3 is perpendicular to the rotation axis of the second rotating mechanism 6. The arrangement of the first rotating mechanism 3 and the second rotating mechanism 6 allows the cleaning mechanism 5 or the trimming mechanism 4 to rotate in multiple directions, covering a wide range of working angles. This enables timely and flexible adjustment of the working position and angle according to actual conditions, reducing the overall space occupied by the multi-functional cleaning vehicle and avoiding interference with other vehicles.

[0040] More specifically, refer again Figures 1 to 4 A first drive member 24 is hinged between the first arm section 21 and the second arm section 22, and a second drive member 25 is hinged between the second arm section 22 and the third arm section 23. The first drive member 24 drives the second arm section 22 to rotate relative to the first arm section 21, and the second drive member 25 drives the third arm section 23 to rotate relative to the second arm section 22. Both the first drive member 24 and the second drive member 25 are connected to a power source module. During operation, the power source module drives the first drive member 24 and the second drive member 25 as needed, thereby driving the second arm section 22 and the third arm section 23 to rotate, thus lifting the trimming mechanism 4 or the cleaning mechanism 5 to the position to be operated.

[0041] Preferably, both the first driving component 24 and the second driving component 25 are hydraulic cylinders, which have better working stability and higher structural strength.

[0042] Furthermore, such as Figure 5 and Figure 6As shown, the first rotating mechanism 3 includes a first rotating bearing 31 and a first rotating platform 32 connected to the first rotating bearing 31. A trimming connecting seat 41 is detachably connected to the first rotating platform 32, and a cleaning connecting seat 51 is also detachably connected to the first rotating platform 32. Specifically, the first rotating mechanism 3 further includes a first connecting seat 33 and a first drive module 34. The first drive module 34 and the first rotating bearing are mounted on the first connecting seat 33. The first drive module 34 includes, for example, a motor and a worm gear reducer. The worm gear reducer drives the first rotating bearing 31, which includes an inner ring and an outer ring. Ball bearings are disposed between the inner and outer rings. The worm gear reducer drives the outer ring to rotate relative to the inner ring. The first rotating platform 32 is fixed to the outer ring and rotates with it. The motor is preferably a hydraulic motor.

[0043] It should be noted that the specific structure of the second slewing mechanism 6 is the same as that of the first slewing mechanism 3. The second slewing mechanism 6 also includes a second connecting seat, a second drive module, a second slewing bearing, and a second slewing platform connected to the second slewing bearing. The second connecting seat is connected to one end of the third arm 23. The second drive module and the second slewing bearing are disposed on the second connecting seat, and the first connecting seat 33 is mounted on the second slewing platform, thereby enabling the second slewing mechanism 6 to rotate relative to the first slewing mechanism 3. The second drive module has the same structure as the first drive module 34, and will not be described in detail here.

[0044] In this embodiment, the multi-functional cleaning vehicle also includes multiple connectors. The first rotating platform 32 is provided with multiple first connecting parts, the trimming connecting seat 41 is provided with multiple second connecting parts, and the cleaning connecting seat 51 is provided with multiple third connecting parts. Each connector can be detachably connected to one first connecting part and one second connecting part, or each connector can be detachably connected to one first connecting part and one third connecting part. The connectors allow for selective assembly of the cleaning mechanism 5 and the trimming mechanism 4, thereby adapting to different operational needs.

[0045] For example, the first connecting part is a first connecting hole formed on the first rotating platform 32, the second connecting part is a second connecting hole formed on the trimming connecting seat 41, and the third connecting part is a third connecting hole formed on the cleaning connecting seat 51. The connecting element is a bolt, and each bolt is threadedly connected to one first connecting hole and one second connecting hole, or each bolt is threadedly connected to one first connecting hole and one third connecting hole. The above structure is simple, easy to assemble and disassemble, has good structural strength, and low cost.

[0046] Furthermore, the cleaning assembly 52 also includes a roller brush driver 523, which drives the cleaning roller brush 522 to rotate. The trimming assembly 42 also includes a trimming driver 423, which drives the trimmer 422 to rotate. Both the roller brush driver 523 and the trimming driver 423 are hydraulic motors.

[0047] Preferably, multiple trimming shears 422 and trimming drive units 423 are provided, for example, three each. The three trimming shears 422 are mounted side by side and rotated at intervals on the trimming mounting base 421. The three trimming drive units 423 drive one trimming shear 422 in turn, which makes the working range of the trimming mechanism 4 larger, which is beneficial to improving trimming efficiency. Moreover, each trimming shear 422 can operate independently and can be started and stopped according to actual working conditions, saving power. Of course, in other embodiments, the number of trimming shears 422 and trimming drive units 423 can also be other, such as four or five.

[0048] Specifically, a water supply tank is installed inside the carriage 12, and a water supply pipe is connected to the water supply tank. The cleaning component 52 also includes a water spray pipe, which is mounted on the cleaning mounting base 521. The water spray pipe has a water inlet and multiple water outlets, and the water inlet is connected to the water supply pipe via a first quick-connect coupling. Each water outlet is equipped with a nozzle. The water supply tank provides cleaning fluid, such as water, to the water spray pipe, allowing the cleaning mechanism 5 to spray cleaning fluid onto the surface to be cleaned, effectively improving the cleaning effect and efficiency. Furthermore, the quick-connect coupling facilitates the assembly and disassembly of the cleaning mechanism 5, saving assembly and disassembly time.

[0049] In this embodiment, the first drive component 24, the second drive component 25, the first rotary mechanism 3, the cleaning component 52, and the trimming component 42 are all connected to the power source module, that is, the hydraulic motor and the hydraulic cylinder are all connected to the power source module. The power source module is used to provide power to the first drive component 24, the second drive component 25, the first rotary mechanism 3, the cleaning component 52, and the trimming component 42.

[0050] The power source module has a hydraulic oil supply pipe, and the hydraulic motor and hydraulic cylinder are connected to the hydraulic oil supply pipe through a second quick-connect connector, which facilitates the assembly and disassembly of the cleaning mechanism 5 and the trimming mechanism 4, saving assembly and disassembly time.

[0051] Specifically, the power source module includes a hydraulic oil tank, a power source, multiple oil pumps and a high-pressure plunger pump. The power source provides power to the multiple oil pumps and the high-pressure plunger. The multiple oil pumps are connected to the hydraulic oil tank and to multiple hydraulic cylinders and hydraulic motors respectively to pump hydraulic oil. The high-pressure plunger pump is connected to the water supply pipe and the water spray pipe through pipelines to pump cleaning fluid to the water spray pipe.

[0052] Preferably, the power unit also includes a transfer case, which is connected to the power source. Multiple oil pumps and a high-pressure plunger pump are connected to the power output end of the transfer case. For example, one oil pump and a dual oil pump are connected to the transfer case, and the high-pressure plunger pump is connected to the transfer case via a universal joint. The power source is an engine, which uses air cooling. Since air-cooled engines are a relatively mature existing technology, they will not be described in detail here.

[0053] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
