Description

Technical Field

[0001] This utility model relates to the field of lawnmower technology, specifically to an easily adjustable lawnmower. Background Technology

[0002] A lawnmower, also known as a lawn mower, lawn trimmer, or lawn mower, is a mechanical tool used for trimming lawns and vegetation. It consists of a cutter head, engine, wheels, a walking mechanism, blades, a handle, and a control unit. The cutter head is mounted on the wheels, and the engine is mounted on the cutter head. The blades are mounted on the output shaft of the engine. The high-speed rotation of the blades by the engine greatly increases the speed, saving lawnmower workers' working time and reducing a lot of manpower.

[0003] Existing lawnmowers have the drawback of not being able to adjust the trimming height, making them time-consuming, laborious, and inconvenient to use. Moreover, lawnmowers often encounter situations where the weeds are too deep, preventing them from passing smoothly and resulting in some weeds not being cut. Utility Model Content

[0013] Furthermore, an improvement of this utility model is that the rack plate and the sliding plate are fixedly connected.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides an easily adjustable lawnmower with the following advantages:

[0016] This easily adjustable lawnmower allows for easy adjustment of the cutting blade height. Simply activate the third motor, which drives the driven wheel via a drive wheel and belt. The driven wheel then drives a threaded rod, which in turn drives a threaded tube. The threaded tube then moves the fixed frame, thus adjusting the cutting blade height. This makes adjustment more convenient, time-saving, and labor-saving, and highly practical. Furthermore, the second motor and drive gear rotate, driving a rack plate. The rack plate then drives a sliding plate, which in turn moves the cutting blade forward, allowing even deep weeds to be cut, further improving the device's effectiveness.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 An easily adjustable lawnmower includes a mounting box 1. A push rod 2 is located on one side of the mounting box 1. Rollers 3 are located on both sides of the bottom of the mounting box 1. A fixing frame 4 is located on the top of the mounting box 1. A sliding plate 5 is slidably mounted inside the fixing frame 4. A rack plate 11 is located on one side of the top of the sliding plate 5. A mounting bracket is located on one side of the top of the fixing frame 4. A second motor 9 is located on the top of the mounting bracket. A drive gear 10 is located at the output end of the second motor 9. The drive gear 10 is located on the side of the rack plate 11 and is meshed with the rack plate 11. The sliding plate 10... A first motor 6 is provided on one side of the top of plate 5. A transmission rod 7 is provided at the output end of the first motor 6. A cutting blade 8 is provided at one end of the transmission rod 7. Threaded rods 15 are provided on both sides inside the mounting box 1. Threaded tubes 17 are provided on the threaded rods 15. The top end of the threaded tubes 17 passes through the mounting box 1 and connects to the fixing frame 4. A driven wheel 16 is provided at the bottom end of the threaded rods 15. A belt 14 is provided on the driven wheel 16. A third motor 12 is provided in the middle of the mounting box 1. A driving wheel 13 is provided at the output end of the third motor 12. One end of the belt 14 is provided on the driving wheel 13.

[0024] In actual use, the above structure first pushes the mounting box 1 through the push rod 2 and roller 3. The first motor 6 drives the transmission rod 7 to rotate, which in turn drives the cutting blade 8 to rotate, cutting the weeds. When the height of the cutting blade 8 needs to be adjusted, the third motor 12 is activated. The third motor 12 drives the drive wheel 13, which in turn drives the driven wheel 16 through the belt 14. The driven wheel 16 drives the threaded rod 15, which in turn drives the threaded tube 17. The threaded tube 17 then drives the fixing frame 4. The fixed frame 4 drives the cutting blade 8 to adjust its height. Operation is simple. When the position of the cutting blade 8 needs adjustment, the second motor 9 is activated. The second motor 9 drives the drive gear 10 to rotate. The rotation of the drive gear 10 drives the rack plate 11 through meshing. The rack plate 11 drives the sliding plate 5, which slides within the fixed frame 4 and drives the cutting blade 8 forward, thus completely adjusting the position of the cutting blade 8. When the mounting box 1 is moved to a position where it is difficult to push, adjusting the position of the cutting blade 8 allows even deep weeds to be cut, further improving the device's effectiveness.

[0025] In this embodiment, slide bars are provided on both sides of the threaded tube 17. The slide bars are slidably connected to the mounting box 1 and fixedly connected to the threaded tube 17, which improves the stability of the threaded tube 17 when sliding up and down.

[0026] In this embodiment, the push rod 2 is welded to the mounting box 1, and an anti-slip sleeve is provided on the push rod 2. The anti-slip sleeve is made of rubber, which improves the performance of the push rod 2.

[0027] In this embodiment, the fixing frame 4 and the threaded tube 17 are connected by bolts, which facilitates the disassembly and maintenance of the fixing frame 4.

[0028] In this embodiment, an inspection door is provided on the side of the installation box 1. The inspection door is detachably connected to the installation box 1, which facilitates the inspection of the interior of the installation box 1.

[0029] In this embodiment, the rack plate 11 and the sliding plate 5 are fixedly connected, which improves the stability of the rack plate 11.

[0030] 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.
