Description

Technical Field

[0001] This utility model relates to the field of lawn mowing, and in particular to a multi-wheel combined contour lawn mowing machine. Background Technology

[0002] A lawn is a mowed and managed ground cover consisting of one or more herbaceous plants. It is typically used to beautify the environment, provide recreational space, and improve soil quality. A lawn mower is a mechanical device specifically designed for mowing and maintaining lawns. It uses rotating blades or other cutting devices to cut grass blades to a set height to keep the lawn neat, beautiful, and flat.

[0003] Current lawn mowers are typically operated by a person pushing the machine to mow the lawn. However, when mowing uneven lawns, current lawn mowers cannot adjust their angle according to the undulations of the ground, making it difficult to adapt to different terrains. Because they cannot flexibly handle differences in ground height, they are prone to mowing some areas too short or too long, resulting in uneven mowing, affecting the quality and efficiency of the mowing. They are also inconvenient to use due to their poor adaptability.

[0004] Therefore, there is a need to design a multi-wheel combination contour lawn mower that can adjust the mowing height and angle to mow uneven lawns, has a wider mowing range, is easy to adapt to different terrains, improves the quality and efficiency of mowing, is flexible and convenient to use, and has strong adaptability. Utility Model Content

[0005] To overcome the shortcomings of current lawn mowers, such as their inability to adjust angles according to ground undulations, difficulty in adapting to different terrains, tendency to cut some areas too short or too long, uneven cutting, affecting the quality and efficiency of mowing, poor adaptability, and inconvenience of use, this utility model provides a multi-wheel combination contour-following lawn mower that can adjust the cutting height and angle to cut uneven lawns, has a wider cutting range, is easy to adapt to different terrains, improves the quality and efficiency of mowing, and is flexible, convenient, and highly adaptable.

[0006] The technical solution is as follows: A multi-wheel combination contour lawn mower includes a mounting plate, a housing, wheels, a push rod, a mowing component, and a storage component. The housing is connected to the upper side of the mounting plate, and two wheels, one in front and one behind, are rotatably connected to the left and right sides of the mounting plate. A push rod is connected to the left side of the mounting plate. The mounting plate is equipped with a mowing component for mowing uneven lawns, and the housing is equipped with a storage component for fixing and storing the mowing component.

[0007] As a further preferred embodiment, the trimming assembly includes a rotating plate, a fixed plate, a motor, a mowing rope, a hydraulic cylinder, and driven wheels. The mounting plate has rotating plates rotatably connected to both the front and rear parts. Two identical rotating plates are rotatably connected to the opposite sides of the rotating plates. The right side of the mounting plate is connected to two fixed plates, each with a motor connected to it. The left and right sides of the rotating plates are also connected to motors. The output shafts of the motors are connected to the mowing ropes. The lower center of each rotating plate is connected to a hydraulic cylinder. Each hydraulic cylinder has a connecting piece on its telescopic end. Driven wheels are rotatably connected to both the front and rear sides of the connecting piece.

[0008] As a further preferred option, the diameter of each wheel is larger than the diameter of the driven wheel.

[0009] As a further preferred embodiment, the storage assembly includes a telescopic storage rack, locking blocks, fixing blocks, springs, and pins. The telescopic storage rack is connected to the upper side of the chassis. Damping is provided between the telescopic end and the fixing end of the telescopic storage rack. Locking blocks are connected to the upper middle part of the two outermost rotating plates. Two fixing blocks are connected to the telescopic end of the telescopic storage rack. Pins are slidably connected to the fixing blocks. Springs are connected between the pins and the fixing blocks on the same side.

[0010] As a further preferred option, the upper part of the locking block is provided with a mating hole.

[0011] As a further preferred option, the fixing block is U-shaped.

[0012] Beneficial effects: 1. This utility model raises the entire device by moving the connecting parts. By pushing the device to move, the grass cutting rope rotates and trims the lawn. The rotating plate will rotate to continue trimming according to the terrain, thereby adjusting the trimming height and angle to trim uneven lawns. The trimming range is wider, making it easier to adapt to lawns on different terrains, improving the quality and efficiency of trimming. It is flexible, convenient, and highly adaptable.

[0013] 2. This utility model extends the telescopic storage rack, and then the rotating plate is rotated by hand, so that the locking block and the fixing block come into contact. Then the pin moves and engages with the fixing block, thereby fixing the corresponding rotating plate. Then the rotating plate is retracted, and the device is pushed away for storage. This allows the rotating plate to be retracted and stored after trimming, making the device easy to store and reducing storage space. Attached Figure Description

[0021] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0022] A multi-wheel combination contour-following lawn mower, such as Figures 1-6 As shown, the assembly includes a mounting plate 1, a housing 2, wheels 3, a push rod 4, a telescopic storage rack 5, a rotating plate 6, a fixed plate 7, a motor 8, a mowing rope 9, a hydraulic cylinder 10, a driven wheel 11, a locking block 12, a fixing block 13, a spring 14, and a pin 15. The housing 2 is connected to the upper side of the mounting plate 1. Two wheels 3 are rotatably connected to the left and right sides of the mounting plate 1. A push rod 4 is connected to the left side of the mounting plate 1. A telescopic storage rack 5 is connected to the upper side of the housing 2. Damping is provided between the telescopic end and the fixed end of the telescopic storage rack 5. Rotating plates 6 are rotatably connected to the front and rear sides of the mounting plate 1. Two identical rotating plates 6 are rotatably connected to the opposite sides of the rotating plates 6. Two fixed plates 7 are connected to the right side of the mounting plate 1. Motors 8 are connected to each plate 7, and motors 8 are also connected to the left and right sides of the rotating plate 6. A grass-cutting rope 9 is connected to the output shaft of each motor 8. A hydraulic cylinder 10 is connected to the lower middle part of each rotating plate 6. A connecting piece is provided on the telescopic end of each hydraulic cylinder 10. Driven wheels 11 are rotatably connected to the front and rear sides of the connecting piece. The diameter of each wheel 3 is larger than the diameter of the driven wheel 11. Locking blocks 12 are connected to the upper middle part of the two outermost rotating plates 6. The upper part of each locking block 12 has a mating hole for easy fixing. Two fixing blocks 13 are connected to the telescopic end of the telescopic storage rack 5. The fixing blocks 13 are U-shaped. Pins 15 are slidably connected to each fixing block 13. A spring 14 is connected between each pin 15 and the fixing block 13 on the same side.

[0023] When lawn mowing is needed, this device can be used. The wheel 3 contacts the lawn, then the pin 15 is pulled, stretching the spring 14 and disengaging the pin 15 from the locking block 12. The rotating plate 6 is then rotated down, bringing the driven wheel 11 into contact with the ground. The pin 15 is then released, the spring 14 returns, and the pin 15 moves back to its original position, causing the telescopic storage rack 5 to retract. Next, depending on the desired mowing length, the hydraulic cylinder 10 is activated, moving the connecting parts and thus the driven wheel 11, raising the entire device. Once the desired height is reached, the hydraulic cylinder 10 is deactivated. The device is then moved by hand using the push rod 4, causing the wheel 3 and driven wheel 11 to rotate. The diameter of the wheel 3 is larger than that of the driven wheel 11. During movement, the motor 8 is activated, driving the mowing rope 9 to mow the lawn. When the lawn surface is uneven... The rotating plate 6 rotates according to the terrain, which in turn drives the corresponding mowing rope 9 and driven wheel 11 to continue mowing. This allows for adjustment of the mowing height and angle to trim uneven lawns, providing a wider mowing range and adaptability to different terrains. It improves the quality and efficiency of mowing, is flexible and convenient to use, and is highly adaptable. After mowing, the motor 8 is turned off, and the telescopic storage rack 5 is extended. The rotating plate 6 is then pulled to rotate, causing the locking block 12 to contact the fixing block 13 (which is U-shaped). The pin 15 is then pulled to move, stretching the spring 14. The pin 15 is then released, the spring 14 rebounds, and the pin 15 moves back to its original position and engages with the fixing block 13, thus fixing the rotating plate 6. The rotating plate 6 is then retracted, and the device is pushed away for storage. This allows the rotating plate 6 to be retracted and stored after mowing, facilitating the storage of the device and reducing storage space.
