Description

Technical Field

[0001] This utility model relates to the field of lawnmower technology, and in particular to a width-adjustable lawnmower. Background Technology

[0002] A lawnmower, also known as a lawn mower, lawn trimmer, or lawn trimmer, is a mechanical tool used to trim lawns, vegetation, and other vegetation. Lawn mowers are widely used for clearing weeds in the wild.

[0003] In wild grasslands, complex terrain such as uphill or downhill slopes may be encountered. Existing lawnmowers often have a fixed mowing part that is difficult to use to cut weeds in complex terrain. The fixed mowing part is also prone to collision with the ground at the junction of the slope, which can easily lead to damage to the mowing part.

[0004] Existing lawnmowers have several mowing blades fixedly connected to the edge of the turntable. The fixed setting of the mowing blades makes it difficult to adjust the length of the cutting part of the blade, and it is also difficult to replace the damaged blades. There are also mowing blades that are bolted to the turntable. The mowing blades need to be fixed with at least two through holes. The setting of multiple through holes affects the strength of the mowing blades, and the back side of the mowing blades lacks support. Utility Model Content

[0005] To address the aforementioned shortcomings, the purpose of this utility model is to provide a width-adjustable lawnmower that can remove weeds, effectively clear weeds in complex terrain, and allows for easy adjustment of the cutting length of the mowing blade. The drive mechanism allows for adjustment of the mounting frame angle, preventing the mowing section from colliding with the ground when facing uphill or downhill slopes. Multiple mounting threaded holes facilitate adjustment of the connection position between the mowing blade and the turntable, thereby adjusting the cutting width. The mounting groove restricts the portion of the mowing blade that overlaps with the turntable and also provides support for the back of the mowing blade.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0019] See Figure 1 , Figure 2 , Figure 3 , Figure 4 This utility model provides a width-adjustable lawn mower, which includes a vehicle body 1. The vehicle body 1 is designed to facilitate driver operation and propel components such as the mounting frame 5 forward. One end of the mounting frame 5 is rotatably connected to the front of the vehicle body 1, and the other end of the mounting frame 5 is equipped with a support roller 9. The support roller 9 and the vehicle body 1 can respectively support both ends of the mounting frame 5. A driver 6 is installed in the middle of the mounting bracket 5. A turntable 7 is located below the driver 6. The driver 6 drives the turntable 7 to rotate. The turntable 7 has several sets of threaded holes, each set of which has several mounting threaded holes 14. The turntable 7 has several grass cutters 8. The grass cutters 8 are connected to the turntable 7 by mounting bolts 11. Each set of threaded holes corresponds to one grass cutter 8. The mounting bolts 11 can cooperate with the mounting threaded holes 14 to install one end of the grass cutter 8 onto the turntable 7. During installation, the grass cutters 8 extend out of the turntable 7 by an equal length (the grass cutter 8 for weeds that are easy to cut extends out of the turntable 7 by a longer length, which can improve the cutting efficiency while ensuring the cutting quality; the grass cutter 8 for weeds that are difficult to cut extends out of the turntable 7 by a shorter length, which avoids the grass cutter 8 extending too far out, resulting in poor cutting effect. When cutting grass in the trench, the position of the grass cutter 8 can be adjusted according to the width of the trench to avoid the grass cutter 8 colliding with the ground). The vehicle body 1 is equipped with a drive device to rotate the mounting frame 5. When the mounting frame 5 rotates, it can change its own angle. When it is at the intersection of the slope, it can change its own angle in advance to cooperate with the slope and avoid the grass cutter 8 from colliding with the ground during the rotation.

[0020] See Figure 1Furthermore, the driving device of this utility model includes a rope body 2, a support frame 3, and an electric reel (not shown in the figure). The electric reel is fixedly installed on the vehicle body 1 and is used to wind up the rope body 2. One end of the rope body 2 is connected to the electric reel, and the other end of the rope body 2 is fixedly connected to the end of the mounting frame 5 away from the vehicle body 1. The support frame 3 is fixedly connected to the vehicle body 1 and is located between the electric reel and the mounting frame 5. A V-shaped wheel 4 is rotatably connected above the support frame 3. The V-shaped wheel 4 is used to support the rope body 2. The setting of the V-shaped wheel 4 can always limit the rope body 2 to the middle groove position of the V-shaped wheel 4, preventing the rope body 2 from detaching from the V-shaped wheel 4. The setting of the support frame 3 can make the height of the connection end between the rope body 2 and the mounting frame 5 lower than the height of the V-shaped wheel 4 when the mounting frame 5 is rotated to the vertical position, preventing the rope body 2 from detaching from the V-shaped wheel 4 and ensuring that the V-shaped wheel 4 can provide stable support for the rope body 2.

[0021] See Figure 1 , Figure 2 , Figure 3 , Figure 4 Furthermore, the various threaded hole groups of this invention are evenly distributed around the center of the turntable 7. This even distribution of threaded hole groups allows the mower blades 8 to be evenly installed on the turntable 7. At least three sets of threaded hole groups are provided. The various mounting threaded holes 14 within each threaded hole group are distributed along a straight line, with their extension lines passing through the center of the turntable 7. By installing the mounting bolts 11 into different mounting threaded holes 14 within one threaded hole group, the length of the mower blades 8 extending out of the turntable 7 can be adjusted. The turntable 7 is fixedly connected to several mounting slots 10 that restrict the rotation of the mower 8. The mounting slots 10 are provided with several first through holes 12 that mate with the mounting threaded holes 14. One end of the mower 8 is provided with a second through hole 13. The mounting slots 10 can restrict the mower and provide support for the back of the mower and the handle at one end, avoiding the need for bolts to resist the reaction force on the mower during mowing, thus helping to prevent the mower from breaking. After passing the stud part of the mounting bolt 11 through the first through holes 12 and the second through holes 13 respectively, the mounting bolt 11 is tightened into the mounting threaded holes 14 to complete the installation of the mower 8.

[0022] Operating principle: When going uphill, the angle of the mounting frame 5 is adjusted before the mower blade 8 collides with the ground (so that the mounting frame 5 is parallel to the uphill slope; the angle of the mounting frame 5 can also be adjusted according to the actual situation. After adjustment, the vehicle body 1 can continue to move forward). The electric reel winds up the rope 2, causing the mounting frame 5 to rotate upward, preventing the mower blade 8 from colliding with the ground. When going downhill, the electric reel does not work (the electric reel can adjust the angle of the mounting frame 5 according to the actual situation), keeping the mounting frame 5 in a horizontal state. The vehicle body 1 moves forward until the mower blade 8 no longer collides with the ground. Then, the electric reel releases the rope to support the roller 9 to contact the ground. When weeds are easy to cut, the mounting bolt 11 is installed in the mounting threaded hole 14 located away from the center of the turntable 7. The mower blade 8 has a larger cutting width, which can improve cutting efficiency. When weeds are difficult to cut, the mounting bolt 11 is installed in the mounting threaded hole 14 located near the center of the turntable 7. The mower blade 8 is shorter, which can avoid cutting too many weeds at the same time and improve the cutting effect.

[0023] In summary, this utility model provides a width-adjustable lawnmower, including a vehicle body. The vehicle body is designed to facilitate operator control, thereby enabling the mowing component to move forward and clear weeds. A mounting frame is rotatably connected to one end of the vehicle body, and a support roller is mounted on the other end of the mounting frame. The support roller provides support to one end of the mounting frame, ensuring it remains parallel to the ground. A driver is mounted in the middle of the mounting frame, and a turntable is positioned below the driver. The driver drives the turntable to rotate, causing the mowing blades to rotate around the turntable to cut weeds. The turntable has several sets of threaded holes, each capable of housing a mowing blade. Each set of threaded holes has several mounting threaded holes, and the turntable has several mowing blades connected to the turntable by mounting bolts. The mowing width of the blades can be adjusted by mounting them in different threaded holes. The vehicle body includes a drive device that rotates the mounting frame, preventing the mowing component from colliding with the ground at the slope boundary.
