[0033] The following is combined with Figure 1-6 This application is described in further detail.

[0034] Example 1:

[0035] The embodiment of the present application discloses a high-efficiency weeding device for landscaping.

[0036] Reference Figure 1 A high-efficiency weeding device for landscaping includes a mounting base 1, a shell 2 and a cutting assembly 3, the cutting assembly 3 is mounted on the shell 2, and the shell 2 is mounted on the mounting base 1; the mounting base 1 is provided with a universal wheel 13, and the universal wheel 13 is used to abut against the ground to move the position of the mounting base 1; a movable rod 12 is tiltedly provided on one side of the mounting base 1, and the staff holds the movable rod 12 to facilitate pushing the mounting base 1.

[0037] The outer wall of the shell 2 is provided with multiple dovetail blocks 21. In this embodiment, three groups of dovetail blocks 21 are provided, and the three groups of dovetail blocks 21 are arranged at intervals along the outer wall of the shell 2; the mounting seat 1 is provided with a dovetail groove 11 for the dovetail blocks 21 to slide. The cooperation between the dovetail blocks 21 and the dovetail groove 11 can ensure the stability of the sliding of the shell 2 on the mounting seat 1.

[0038] Reference Figure 2An extension portion 22 is integrally formed at one end of the dovetail block 21 in the middle. The staff pulls the extension portion 22 to change the position of the dovetail block 21 in the dovetail groove 11 to adjust the height position of the cutting assembly 3; the dovetail block 21 is provided with a plurality of mounting grooves 24, all of which are arranged at intervals along the length direction of the dovetail block 21, and one of the mounting grooves 24 is arranged on the extension portion 22.

[0039] A mounting block 4 is provided on the upper surface of the mounting seat 1, and the mounting block 4 abuts against one side of the extension portion 22. The mounting block 4 is provided with a mounting hole 41, and the two ends of the mounting hole 41 are respectively connected to the opposite side walls of the mounting block 4; when the shell 2 is fixed to the mounting seat 1, the mounting hole 41 is arranged opposite to one of the mounting grooves 24, and a plug rod 44 is passed through the mounting hole 41 and the mounting groove 24, and the plug rod 44 is fixed to the inner wall of the mounting groove 24 by the anti-slip component 5.

[0040] In this embodiment, the anti-slip member 5 includes a first threaded portion 51 and a second threaded portion 52 that cooperates with the first threaded portion 51. The first threaded portion 51 is disposed on the outer wall of the plug rod 44, and the second threaded portion 52 is disposed on the inner wall of the mounting groove 24. The cooperation between the first threaded portion 51 and the second threaded portion 52 can connect the plug rod 44 to the inner wall of the mounting groove 24. This installation method is more stable and can reduce the possibility of the plug rod 44 loosening during operation of the weeding device.

[0041] Reference Figure 1 and Figure 3 The cutting assembly 3 includes a mounting portion 33, a motor 31 and a plurality of cutting ropes 32. The mounting portion 33 is rotatably mounted on the housing 2. The motor 31 is mounted on the housing 2 to drive the mounting portion 33 to rotate. All cutting ropes 32 are mounted on the mounting portion 33 and are spaced apart along the outer peripheral wall of the mounting portion 33.

[0042] When the motor 31 is started, it can drive the mounting portion 33 to rotate. As the mounting portion 33 rotates, all the cutting ropes 32 are swung and generate centrifugal force, so that they can quickly and effectively contact the grass, making it easy to cut into the grass blades and cut them off.

[0043] Reference Figure 4 The mounting portion 33 includes a rotating rod 332 and a mounting sleeve 331. The rotating rod 332 is rotatably mounted on the housing 2, and the output shaft of the motor 31 is connected to the rotating rod 332; movable grooves 34 are opened on the opposite side walls of the rotating rod 332, and a fixed rod 35 is movably mounted in the movable groove 34; a hemispherical head 36 is integrally formed on the side of the fixed rod 35 away from the movable groove 34; a second spring 37 is provided between the fixed rod 35 and the inner wall of the telescopic groove, and the elastic force of the second spring 37 is used to drive the fixed rod 35 to move toward the side away from the movable groove 34.

[0044] All cutting ropes 32 are installed with a mounting sleeve 331. In this embodiment, the mounting sleeve 331 has an opening with a wall thickness on one side that is smaller than the radius of the hemispherical head 36. A fixing groove 38 is provided on the outer wall of the mounting sleeve 331, and one side of the fixing groove 38 is connected to the inner wall of the mounting sleeve 331.

[0045] When the mounting sleeve 331 is sleeved on the outer wall of the connecting rod and the movable groove 34 is arranged opposite to the fixed groove 38, the hemispherical head 36 is passed through the fixed groove 38 under the elastic force of the second spring 37 and exposed to the outside; that is, the connection between the mounting sleeve 331 and the connecting rod is completed, so that when the motor 31 drives the connecting rod to rotate, the cutting rope 32 swings.

[0046] When the cutting rope 32 needs to be disassembled for inspection, the staff first presses the hemispherical head 36 so that the hemispherical head 36 enters the fixed groove 38; then the staff pulls the installation sleeve 331 to make the outer wall of the hemispherical head 36 abut against the inner wall of the fixed groove 38, so that the hemispherical head 36 enters the movable groove 34 under the guidance of the outer wall of the hemispherical head 36, so that the installation sleeve 331 can be removed from the connecting rod.

[0047] The implementation principle of Example 1 of the present application is:

[0048] The outer shell 2 is slidably installed on the mounting base 1, thereby changing the distance between the cutting component 3 and the ground, so as to change the cutting height of the grass; and the first threaded portion 51 and the second threaded portion 52 cooperate to firmly connect the plug-in rod 44 with the inner wall of the mounting groove 24. This installation method is more convenient, so as to fix the outer shell 2 and the mounting base 1, thereby improving the convenience of adjusting the height position of the cutting component 3.

[0049] Example 2:

[0050] The embodiment of the present application discloses a high-efficiency weeding device for landscaping.

[0051] Reference Figure 5 and Figure 6 The difference between Example 2 of the present application and Example 1 is that the anti-slip component 5 includes a rubber layer 53, a first spring 55 and an anti-slip plate 54, and the rubber layer 53 is arranged on the outer wall of the plug-in rod 44; so that the plug-in rod 44 is inserted into the installation groove 24 by interference fit, thereby reducing the possibility of the plug-in rod 44 detaching from the installation groove 24.

[0052] Reference Figure 5A removal groove 42 connected to the mounting hole 41 is opened on one side of the mounting block 4, and the inner diameter of the removal groove 42 is larger than the inner diameter of the mounting hole 41; when the plug-in rod 44 is inserted into the mounting hole 41 and inserted into the mounting groove 24, the plug-in rod 44 is partially located in the removal groove 42; because there is a gap between the outer wall of the plug-in rod 44 and the inner wall of the removal groove 42, it is convenient for the staff to pull the plug-in rod 44 out of the removal groove 42.

[0053] Reference Figure 6 The mounting block 4 has an anti-slip groove 43 on one side of the removal groove 42, and the extension direction of the anti-slip measure is perpendicular to the sliding direction of the dovetail block 21; an anti-slip block 56 is provided on one side of the anti-slip plate 54, and the anti-slip block 56 is slidably installed in the anti-slip groove 43; the two ends of the second spring 37 are respectively connected to the anti-slip block 56 and the inner wall of the anti-slip groove 43; the elastic force of the second spring 37 is used to drive the anti-slip block 56 to cover the surface of the mounting port under normal conditions.

[0054] By making the extension direction of the anti-slip groove 43 perpendicular to the extension direction of the dovetail block 21, the anti-slip plate 54 can be reduced from jumping during operation of the weeding device, and the stability of the anti-slip plate 54 covering the surface of the removal groove 42 can be increased.

[0055] The implementation principle of Example 2 of this application is:

[0056] Under normal circumstances, the anti-slip plate 54 is driven by the elastic force of the first spring 55 to cover the surface of the mounting hole 41. When the plug-in rod 44 is inserted into the mounting hole 41 and the mounting groove 24, the plug-in rod 44 can abut against the anti-slip plate 54; thereby ensuring that the plug-in rod 44 is not easily dislodged from the mounting hole 41 when subjected to external force, thereby improving the stable height effect.

[0057] The above are preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
