DETAILED DESCRIPTION
[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] Reference Figure 1 , Figure 2 and Figure 3The utility model provides an embodiment: a lawn mower suitable for multiple scenes, including a shell 1 and two side cover plates 9, a plurality of adjustment slots 2 are equidistantly provided on the left and right sides of the shell 1, a fixing seat 3 is fixedly installed on the front side of the top wall of the shell 1, a hydraulic motor 4 is fixedly connected to the inner wall of the fixing seat 3, a gearbox 5 is fixedly connected to the output end of the hydraulic motor 4, a cutting knife 6 is rotatably installed on the bottom of the gearbox 5, a rotating column 7 is rotatably connected to the left and right sides of the cutting knife 6, a swinging blade 8 is fixedly connected to the outer walls of the two rotating columns 7, vertical slots 10 are provided on the left and right sides of the inner walls of the two side cover plates 9, two adjusting bolts 11 are equidistantly threaded through the far side of the two side cover plates 9, and the adjacent sides of the plurality of adjusting bolts 11 are threadedly connected to the inside of the corresponding adjusting slots 2;
[0031] Specifically, by rotating multiple adjustment bolts 11, the user can accurately adjust the height of the side cover plate 9. The adjustment bolts 11 are tightly combined with the corresponding adjustment slots 2 to ensure that the height of the two side cover plates 9 can be stably fixed on both sides of the shell 1. This design allows the lawn mower to adjust the mowing height according to different usage requirements, thereby adapting to mowing work in different scenarios. During the specific operation process, when the hydraulic motor 4 is started, the gearbox 5 will switch the speed as needed, thereby driving the cutting knife 6 to rotate. Under the action of centrifugal force, the two swing blades 8 can rotate synchronously to form a larger cutting area, which enables the lawn mower to cover a wider area when mowing, thereby improving work efficiency. It is worth mentioning that the design of the side cover plate 9 also fully considers the stability and ground contact of the lawn mower. When the lower part of the side cover plate 9 is level with the ground, the entire lawn mower can slide smoothly on the grass to start mowing.
[0032] Reference Figure 2 The left and right rear ends of the top wall of the shell 1 are fixedly connected with locking plates 13, the inner walls of the two locking plates 13 are threadedly connected with threaded knobs 14, the adjacent sides of the two threaded knobs 14 are fixedly connected with connecting plates 15, the tops of the two connecting plates 15 are fixedly connected with hanging plates 16, the front and rear ends of the right sides of the hanging plates 16 are fixedly installed with tensioning chains 17, the right sides of the two tensioning chains 17 are fixedly connected with fixing plates 18, and the bottom of the fixing plate 18 is fixedly connected to the right side of the shell 1;
[0033] Specifically, the connecting plate 15 and the locking plate 13 are connected to each other by two threaded knobs 14, and the hanging plate 16 is fixed on the locking plate 13. This design makes it easy to adjust the tightness between the connecting plate 15 and the locking plate 13 by turning the threaded knob 14, thereby adjusting the inclination angle of the hanging plate 16. The importance of adjusting the inclination angle of the hanging plate 16 is self-evident. By adjusting the inclination angle, the blade of the lawn mower can maintain the same height when mowing, thereby improving the cutting effect. In addition, a reasonable inclination angle can also help avoid uneven cutting during mowing.
[0034] Reference Figure 1 A curtain 19 is fixedly installed on the right side of the fixed plate 18, and a square groove is opened in the middle of the curtain 19; the left and right bottoms of the two side cover plates 9 are both provided with arc surfaces, and the outer sides of the two side cover plates 9 are both designed to be smooth;
[0035] Specifically, the chain curtain 18 can prevent cutting debris from splashing and filter out some debris, gravel, etc. in the grass to protect the swing knife. The left and right bottoms of the two side cover plates 9 are provided with curved surfaces, and the outer sides of the two side cover plates 9 are rounded, making it smoother to push the lawn mower.
[0036] Reference Figure 2 and Figure 3 , the middle parts of the plurality of threaded knobs 14 are fixedly connected with gaskets 12; the middle part of the cutting knife 6 is provided with a groove 21, and the groove 21 is designed in a trapezoidal shape; the front and rear ends of the left bottom of the hanging plate 16 are fixedly connected with hanging pieces 20; the appearance of the two swinging blades 8 is designed in a Z shape;
[0037] Specifically, the gasket 12 can protect the left and right sides of the housing 1 and reduce the rotation damage of the threaded knob 14. The hanging piece 20 makes it easy to install and fix the hanging plate 16. The Z-shaped design of the two swing blades 8 improves the cutting effect of the swing blades 8.
[0038] Working principle: When starting to mow the lawn, the height of the side cover plate 9 can be adjusted by turning a plurality of adjusting bolts 11, so that the adjusting bolts 11 are fixed in the corresponding adjusting slots 2, thereby ensuring that the two side cover plates 9 can adjust the mowing height according to the use requirements, which is convenient for use in different scenes. By starting the hydraulic motor 4, the cutting knife 6 is rotated at the switching speed of the gearbox 5, so that under the action of centrifugal force, the two swinging blades 8 can rotate synchronously, thereby increasing the cutting range, making the lower part of the side cover plate 9 flat against the ground, so that the entire lawn mower slides on the grass, and then starts mowing, thereby increasing the application range of the lawn mower, avoiding the situation of its flexibility being reduced, and achieving the purpose of using it in multiple scenes, and by turning the two threaded knobs 14, the connection plate 15 and the locking plate 13 are loosened, so that the inclination angle of the hanging plate 16 can be adjusted, so that the mowing work can be kept at the same height in cooperation with the two tensioning chains 17, thereby improving the cutting effect and avoiding the situation of uneven cutting during mowing.
[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
