[0052] An operation method of a landscaping maintenance device includes:

[0053] S100. On the premise of clarifying the position of the waterweeds in the water and ensuring that there are no aquatic ornamental plants near the waterweeds, use the control system 8 to control the height adjustment mechanism 5 to adjust the heights of the waterweed cleaning mechanism 3 and the repair fluid spraying part 4. It should be noted that the position of the repair fluid spraying part 4 is always higher than the highest position of the waterweeds to prevent the waterweeds from entangling the repair fluid spraying part 4. When the position of the waterweeds in the water is relatively deep, the repair fluid spraying part 4 will enter the water;

[0054] S200, using the driving unit 11 to control the rotation of the circular tube 12, the rotating circular tube 12 not only achieves the purpose of controlling the reciprocating lifting and lowering motion of the shaped frame 21, the fixing rod 22 and the sleeve ring 32 by means of the sliding connection between the curved guide rail 13 and the ball head 23 and the limiting hole 511 to limit the shaped frame 21, but also uses the square tube 15 to drive the waterweed cleaning mechanism 3 to rotate with the circular tube 12 as the axis, and the sleeve ring 32 moving up and down along the square tube 15 not only controls the two main blades 361 to swing towards or away from each other with the fixing pin 17 as the axis through the active connection between the first connecting rod 33 and the second connecting rod 34, but also can control the third connecting rod 37 and the rigid tube 42 to make reciprocating horizontal movements along the three-way pipe 18;

[0055] S300, using the control system 8 to control the hull 7 to move on the water surface, the two main blades 361 rotating with the circular tube 12 as the axis are used to entangle the waterweeds, and the two main blades 361 swinging in the direction of approaching or moving away from each other with the fixed pin 17 as the axis can not only expand the scope of entanglement of the waterweeds, but also can use the two main blades 361 and a plurality of auxiliary blades 362 to cut the waterweeds into a plurality of sections, which is convenient for later collection;

[0056] S400. When there is pollution in the water and it needs to be purified, the control system 8 is used to control the repair liquid conveying component 6 to spray the repair liquid through the circular tube 12, the square tube 15, the three-way pipe 18, the rigid tube 42 and the spray valve 41. The spray valve 41 achieves the purpose of adjusting the spray radius by following the third connecting rod 37 and the rigid tube 42 to make reciprocating horizontal movements along the three-way pipe 18. In combination with the stirring effect of the two main blade bodies 361 rotating with the circular tube 12 and the fixed pin 17 as the axis, the repair liquid can be fully mixed with the water.

[0057] 3500. When only the aquatic ornamental plants on the water surface need to be maintained, the water grass cleaning part 36 is removed from the end of the second connecting rod 34, and then the height of the repair liquid spraying part 4 is adjusted according to the position of the aquatic ornamental plants using the S100 method, and then the repair liquid is sprayed on the surface of the aquatic ornamental plants using the S400 method.

[0058] To sum up, by utilizing the design of the combination of the driving mechanism 1, the transmission mechanism 2, the aquatic plant cleaning mechanism 3 and the repair liquid spraying part 4, the two main blades 361 rotating with the circular tube 12 as the axis entangle the aquatic plants, while the two main blades 361 swinging in the direction of approaching or moving away from each other with the fixed pin 17 as the axis can not only expand the range of entangled aquatic plants, but also can use the two main blades 361 and a plurality of auxiliary blades 362 to cut the aquatic plants into several sections. When there is pollution in the water that needs to be purified, the spray valve 41 achieves the purpose of adjusting the spraying radius by following the third connecting rod 37 and the rigid tube 42 to make reciprocating horizontal movements along the three-way pipe 18. With the stirring effect of the two main blades 361 rotating with the circular tube 12 and the fixed pin 17 as the axis, the repair liquid can be fully mixed with the water, which has the characteristics of efficiently cleaning aquatic plants in the water and efficiently purifying water quality, thereby improving the quality of aquatic plant maintenance and water environment maintenance.

An operating method of a garden greening maintenance device, applied to a garden greening maintenance device according to any one of claims 1 to 7, characterized in that: include: S100, on the premise of clarifying the position of the waterweed in the water, using the control system (8) to control the height adjustment mechanism (5) to adjust the height of the waterweed cleaning mechanism (3) and the repair liquid spraying unit (4); S200, using the driving unit (11) to control the rotation of the circular tube (12), the rotating circular tube (12) not only uses the curved guide rail (13) and the transmission mechanism (2) to control the sleeve (32) to move up and down along the square tube (15), but also uses the square tube (15) to drive the waterweed cleaning mechanism (3) to rotate around the circular tube (12) as the axis, the sleeve (32) moving up and down along the square tube (15) not only controls the two main blades (361) to swing towards or away from each other around the fixed pin (17) as the axis through the movable connection between the first connecting rod (33) and the second connecting rod (34), but also can control the third connecting rod (37) and the rigid tube (42) to make reciprocating horizontal movements along the three-way tube (18); S300, using the control system (8) to control the hull (7) to move on the water surface, the two main blades (361) rotating with the circular tube (12) as the axis are used to entangle the waterweeds, and the two main blades (361) swinging in the direction of approaching or moving away from each other with the fixed pin (17) as the axis can not only expand the range of entanglement of the waterweeds, but also use the two main blades (361) and the plurality of auxiliary blades (362) to cut the waterweeds into a plurality of sections, so as to facilitate later collection; S400, using a control system (8) to control the repair liquid delivery assembly (6) to spray the repair liquid through the circular tube (12), the square tube (15), the three-way tube (18), the rigid tube (42) and the spray valve (41), and cooperating with the stirring effect of the two main blade bodies (361) rotating with the circular tube (12) and the fixed pin (17) as the axis on the water, the repair liquid can be fully mixed with the water.
