DETAILED DESCRIPTION

[0031] The preferred technical solutions of the present invention are described in detail below with reference to the accompanying drawings.

[0032] Example 1

[0033] A garden lawn electric weeder, such as Figure 1-Figure 4 As shown, it includes a connecting rod 1, a servo motor 11, a protective plate 1101, a rotating rope 12, a rotating disk 1201, a first connecting frame 13, a mounting block 1301, a pressure ring 14, a screw rod 15, a connector 16, a spring 17 and a guide block 18. The servo motor 11 is fixedly connected to the right side of the connecting rod 1, the protective plate 1101 is fixedly connected to the bottom of the connecting rod 1, the output end of the servo motor 11 is fixedly connected to the rotating disk 1201, the rotating rope 12 is fixedly connected to the left and right sides of the rotating disk 1201, the connector 16 is clamped at the bottom of the connecting rod 1, and the connector The right side of 16 is rotatably connected to the first connecting frame 13 through a damping ring, and the right end of the first connecting frame 13 is rotatably connected to the mounting block 1301 through a damping ring. The mounting block 1301 is slidably connected to guide blocks 18 on both the front and rear sides, and a pressure ring 14 is fixedly connected between the bottom ends of the front and rear guide blocks 18, and the pressure ring 14 is pressed and fitted with the rotating rope 12. A spring piece 17 is fixedly connected to the left side of the pressure ring 14, and the spring piece 17 is pressed and fitted with the output shaft of the servo motor 11. A screw rod 15 is threadedly connected to the middle part of the mounting block 1301, and the screw rod 15 is rotatably connected to the pressure ring 14.

[0034] When a worker needs to trim the lawn of a garden, he can hold the connecting rod 1 and start the servo motor 11. The servo motor 11 will drive the turntable 1201 and the rotating rope 12 to rotate at high speed and cut the grass. The cutting height can usually be adjusted by changing the worker's holding position. When the required cutting height is low and the protective plate 1101 cannot meet the demand by being close to the lawn, the connector 16 can be installed on the connecting rod 1 first, and the first connecting frame 13 and the mounting block 1301 can be rotated to adjust so that the mounting block 1301 is close to the right side of the servo motor 11. During this period, the spring piece 17 will first contact the output shaft of the servo motor 11 as the mounting block 1301 moves. and is squeezed, the spring piece 17 is deformed and deflected to the right. When the spring piece 17 moves to separate from the output shaft of the servo motor 11, the spring piece 17 will return to its original state under the action of its own elasticity. Thereafter, the screw rod 15 can be rotated as needed to adjust the guide block 18, the pressure ring 14, the spring piece 17 and other components to a suitable height. At this time, when the servo motor 11 is started again and the turntable 1201 and the rotating rope 12 are driven to rotate at high speed, the outer side of the rotating rope 12 will be deformed and deflected downward under the restriction of the pressure ring 14 and the spring piece 17, thereby changing the cutting height of the outermost end of the rotating rope 12, so that the cutting height of the rotating rope 12 can be adjusted as needed to meet the needs of different cutting heights.

[0035] Example 2

[0036] On the basis of Example 1, Figure 5 and Figure 6 As shown, it also includes a leveling mechanism, which is arranged on the guide block 18. The leveling mechanism includes a limit frame 2, a weight block 21, a guide frame 22, a slide rod 23 and a spring 24. The guide frame 22 is fixed between the tops of the front and rear guide blocks 18. The middle part of the guide frame 22 is fixed with a slide rod 23. The right side of the guide frame 22 is slidably connected to the limit frame 2. The front and rear sides of the limit frame 2 are fixed with weight blocks 21. The outside of the slide rod 23 is provided with a spring 24. The two ends of the spring 24 are respectively fixed to the guide frame 22 and the limit frame 2.

[0037] like Figure 5 and Figure 6 As shown, the limiting frame 2 is cylindrical on both the front and rear sides.

[0038] When the screw rod 15 rotates and drives the guide block 18, the pressure ring 14 and the spring 17 to move downward, the guide frame 22 and the slide bar 23 will also move downward with the guide block 18, and the limit frame 2 and the weight block 21 will always keep close to the lawn under the action of their own gravity, so the limit frame 2 will slide relative to the guide block 18, and the spring 24 will be compressed immediately. At this time, the bottom of the limit frame 2 and the top of the rotating rope 12 are at the same horizontal plane. When the user's holding posture changes and the protective When the right ends of the plate 1101, the turntable 1201 and the rotating rope 12 are tilted upward, the limit frame 2 and the weight block 21 will move downward and stick to the ground under the action of their own gravity and the elastic force of the spring 24. At this time, when the servo motor 11 is started and drives the turntable 1201 and the rotating rope 12 to rotate at high speed, the right side of the rotating rope 12 will be deformed and deflected downward under the restriction of the limit frame 2, thereby preventing the cutting height of the right end of the rotating rope 12 from changing and affecting the cutting flatness of the lawn by this electric weed cutter.

[0039] like Figure 7 and Figure 8 As shown, a protective mechanism is also included, which is arranged on the mounting block 1301. The protective mechanism includes a protective cloth 3, a first mounting frame 31, a second connecting frame 32 and a folding frame 33. The two second connecting frames 32 are respectively fixed to the front and rear parts of the right side of the mounting block 1301. The second connecting frame 32 is rotatably connected to the folding frame 33 on the right side, and the folding frame 33 is rotatably connected to the first mounting frame 31 on the right side. The protective cloth 3 is fixed between the front and rear folding frames 33, and the protective cloth 3 is also fixed between the folding frame 33 and the adjacent first mounting frame 31.

[0040] like Figure 7 and Figure 8 As shown, the protective cloth 3 is made of transparent plastic material.

[0041] When the rotating rope 12 cuts the grass and causes a lot of grass debris to splash everywhere, the first mounting frame 31 and the folding frame 33 can be rotated and unfolded, and the protective cloth 3 is also unfolded to cover the right side of the rotating rope 12 to prevent grass debris from splashing, and the protective cloth 3 made of transparent plastic will not block the user's line of sight. In this way, the protection area and protection effect of this electric weed cutter for the user can be improved without blocking the user's field of vision. When not needed, the folding frame 33 and the first mounting frame 31 and other components can be folded up to reduce the floor space and facilitate storage.

[0042] like Fig. 9As shown, a supporting mechanism is also included, which is arranged on the connector 16. The supporting mechanism includes a second mounting frame 4, a threaded rod 41, a top frame 42, a pull rope 43 and a rotating sleeve 44. The two second mounting frames 4 are rotatably connected to the front and rear sides of the connector 16 respectively. The bottom of the second mounting frame 4 is fixedly connected to the threaded rod 41, the external threaded connection of the threaded rod 41 is connected to the top frame 42, the external rotatable connection of the top frame 42 is connected to the rotating sleeve 44, and a pull rope 43 is fixedly connected between the rotating sleeve 44 and the protective cloth 3.

[0043] like Fig. 9 As shown, the bottom end of the top frame 42 is spherical.

[0044] Before cutting the grass by the rotating rope 12, the worker can also rotate the top frame 42 in the forward direction according to the required cutting height. Under the action of the threaded rod 41, the top frame 42 will rotate and move downward until it contacts the lawn. At this time, the worker can use the top frame 42 to support the connecting rod 1 and other components to relieve the grip pressure, thereby avoiding the worker's hand shaking due to long-term grip and affecting the cutting flatness of the lawn by this electric weed cutter. The downward movement of the top frame 42 will also drive the rotating sleeve 44 to move downward and will gradually straighten the pull rope 43. The straightened pull rope 43 can pull the protective cloth 3 to keep the protective cloth 3 taut, thereby improving the protection effect and avoiding the folding frame 33 from being accidentally folded. When not needed, the top frame 42 can be reversed, and the top frame 42 will rotate and move upward to reset, and the pull rope 43 will be loosened immediately. After that, the second mounting frames 4 on the front and rear sides can be rotated to the right and folded, so that subsequent workers can store this electric weed cutter.

[0045] like Fig.10 and Fig.11 As shown, a spraying mechanism is also included, which is arranged on the connecting rod 1. The spraying mechanism includes a liquid storage tank 5, a liquid pump 51, a connecting pipe 52, a spray plate 53, a liquid guide pipe 54 and a bracket 55. The liquid storage tank 5 is clamped on the lower part of the connecting rod 1, and the liquid pump 51 is clamped on the top of the connector 16. The liquid pump 51 and the liquid storage tank 5 are fixedly connected and connected with the liquid guide pipe 54. The bracket 55 is clamped on the top of the second mounting frame 4. The spray plate 53 is rotatably connected to the left side of the bracket 55 through a damping ring. The spray plate 53 and the liquid pump 51 are fixedly connected and connected with the connecting pipe 52.

[0046] When workers need to inhibit the growth of grass, they can also install the bracket 55, the liquid storage tank 5 and the liquid pump 51 on the second mounting frame 4, the connecting rod 1 and the connector 16 respectively, and the liquid pump 51 can be started when the grass is cut by the rotating rope 12. The liquid pump 51 will make the weed killer retarder in the liquid storage tank 5 pass through the liquid guide tube 54 and the connecting tube 52 and enter the spray plate 53, and finally spray out from the spray plate 53. During this period, the workers can adjust the inclination angle of the spray plate 53 as needed to adjust the spraying range of the spray plate 53. The sprayed weed killer retarder can not only inhibit the growth of grass, but also reduce the dust generated by weeding. The liquid pump 51 can be turned off when not needed.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
