[0026] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings.

[0027] Example:

[0028] Please see the appendix Figure 1 - Appendix Figure 6 This utility model provides an intelligent greening pruning robot, including a crushing and collecting mechanism 1, a shearing mechanism 2, a lifting and weeding mechanism 3, a maintenance and irrigation mechanism 4, and a transport vehicle 5. The transport vehicle 5 is provided with a cargo box frame 51 on the upper part and a battery pack 52 in the middle part. The crushing and collecting mechanism 1 is located at the upper front end of the transport vehicle 5, the shearing mechanism 2 is located at the lower front end of the transport vehicle 5, the lifting and weeding mechanism 3 is located at the bottom of the transport vehicle 5, and the maintenance and irrigation mechanism 4 is located at the rear of the transport vehicle 5.

[0029] In this embodiment, the battery pack 52 is installed on the transport vehicle body 5 and connected to the motors and control systems of each mechanism via wires to ensure stable power supply. Photovoltaic panels 18 are installed on top of the vacuum power collection frame 17 to absorb solar energy and supplement the battery pack 52 with power.

[0030] The crushing and collecting mechanism 1 includes a plow blade 11 and a housing 12. The plow blade 11 is installed inside the housing 12. A mechanical arm 13 is fixedly connected to the housing 12. The mechanical arm 13 has a flange 14 at its tail end, and the flange 14 is fixedly connected to the upper front end of the transport vehicle body 5. A blower 15 is fixedly connected to the tail end of the housing 12, and a ventilation pipe 16 is fixedly connected to the blower 15. A vacuum pressure collecting frame 17 is connected to the end of the ventilation pipe 16 away from the blower 15. The vacuum pressure collecting frame 17 is installed inside the cargo bucket frame 51. A photovoltaic panel 18 is installed on the top outer wall of the vacuum pressure collecting frame 17.

[0031] In this embodiment, the robotic arm 13 is fixed to the upper front of the vehicle body via flange 14, and the distance between the plow blade 11 and the housing 12 is adjusted to ensure efficient leaf and branch crushing. One end of the ventilation pipe 16 is connected to the exhaust fan 15, and the other end is connected to the vacuum collection frame 17 inside the cargo bucket frame 51 to form a closed collection channel.

[0032] The shearing mechanism 2 includes an electric push rod 21, which is fixedly connected to the lower front end of the transport vehicle body 5. The piston rod of the electric push rod 21 is fixedly connected to a connector 22, and a guillotine frame 23 is fixedly connected to the outer wall of one end of the connector 22. A first shearing guillotine 24 is fixedly connected to the bottom outer wall of the guillotine frame 23 by screws, and a first stepper motor 25 is fixedly connected to one side outer wall of the guillotine frame 23 by screws. The output shaft of the first stepper motor 25 is fixedly connected to a centrifugal disc 26 by a coupling, and a rack and pinion belt 27 is connected to the outer wall of the centrifugal disc 26. The centrifugal disc 26 and the rack and pinion belt 27 mesh with each other, and a second shearing guillotine 28 is fixedly connected to the outer wall of the rack and pinion belt 27.

[0033] In this embodiment, when performing greening operations on the branches of high-strength hedge plants in different regions, the extension rod of the electric push rod 21 can pull the connector 22 when it retracts. The connector 22 pulls the guillotine frame 23 upward, thereby adjusting the height of the first shearing guillotine 24. At this time, when the first stepper motor 25 starts, the centrifugal disc 26 will rotate. The centrifugal disc 26 drives the rack and belt 27 to move, so that the second shearing guillotine 28 and the first shearing guillotine 24 are staggered at a certain angle to cut and prune the high-strength branches.

[0034] The lifting and weeding mechanism 3 includes a second stepper motor 31. The output shaft of the second stepper motor 31 is fixedly connected to a lead screw 32 via a coupling. A cross lifting rod 33 is screwed onto the outer wall of the lead screw 32. The upper end of the cross lifting rod 33 is fixedly connected to the lower middle part of the transport vehicle body 5, and the lower end of the cross lifting rod 33 is fixedly connected to a wrapping disc 34. A high-speed rotating blade 35 is installed on the inner top wall of the wrapping disc 34.

[0035] The second stepper motor 31 starts, driving the lead screw 32 to rotate, causing the slider of the cross lifting rod 33 to move along the lead screw 32, thus achieving height adjustment. When the specified height is reached, the power source drives the transmission system, causing the high-speed rotating blade 35 to rotate at high speed to achieve cutting. The high-speed rotating blade 35 installed inside the enclosing disc 34 can cause the trimmed and broken branches and leaves to be splashed around under the action of centrifugal force and then controlled to be on the ground after hitting the inner wall of the enclosing disc 34.

[0036] The maintenance and irrigation mechanism 4 includes a swing motor 41, which is mounted on the top outer wall of the cargo bucket frame 51. The output shaft of the swing motor 41 is fixedly connected to a sprinkler pipe 42. A water inlet pipe 43 is fixedly connected to the bottom outer wall of the sprinkler pipe 42, and a water tank 44 is fixedly connected to one end of the water inlet pipe 43. The maintenance and irrigation mechanism 4 also includes a servo motor 45, which is fixedly connected to the outer wall of the cargo bucket frame 51 by screws. A pressure pump 46 is fixedly connected to the output end of the servo motor 45. A cartridge 47 is fixedly connected to the input end of the pressure pump 46, and a spray pipe 48 is fixedly connected to the output end of the pressure pump 46, with the spray pipe 48 located at the rear of the cargo bucket frame 51.

[0037] The swing motor 41 operates to make the water jet from the sprinkler pipe 42 swing horizontally within a range of ±100°. The water inlet pipe 43 connects to the water tank 44 to supply water to the sprinkler pipe 42. The servo motor 45 starts and drives the pressure pump 46 to work. The solution in the cartridge 47 flows into the solution chamber of the pressure pump 46 through the input end. The high-pressure solution flows out from the output end of the pressure pump 46 and enters the spray pipe 48. The spray pipe 48 sprays the solution to meet the pesticide application requirements. The swing motor 41 and the servo motor 45 respectively control the swing range of the sprinkler pipe 42 and the spraying pressure of the pressure pump 46 to ensure uniform irrigation and pesticide coverage.

[0038] Working principle:

[0039] Pruning and Crushing: After the equipment is started, the robotic arm 13 adjusts the working posture of the plow blade 11 according to the preset program to cut and crush the branches and leaves. The high-speed rotating blade 35 is adjusted to the vegetation pruning height by the lifting and weeding mechanism 3 for precise cutting.

[0040] Vacuum collection: After the exhaust fan 15 is started, negative pressure is generated, and the broken branches and leaves are sucked into the vacuum collection frame 17 through the ventilation pipe 16 for temporary storage, so as to avoid the debris from flying and polluting the environment.

[0041] High-intensity shearing: When encountering thick branches, the electric push rod 21 drives the guillotine frame 23 to press down, the first stepper motor 25 drives the centrifugal disc 26 to rotate, and the first shearing guillotine 24 and the second shearing guillotine 28 are linked by the rack and pinion belt 27 to cut in an alternating manner, thus completing the high-intensity branch treatment.

[0042] Irrigation and spraying: Water in water tank 44 is transported to sprinkler pipe 42 through inlet pipe 43, and swing motor 41 drives it to swing left and right to achieve wide-angle irrigation. The liquid pesticide in pesticide cylinder 47 is pressurized by pressure pump 46 and then atomized and sprayed out through spray pipe 48 to complete precise pesticide application.

[0043] Energy Management: Photovoltaic panels 18 convert solar energy into electrical energy and store it in battery packs 52 to ensure continuous operation of the equipment.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
