Description

Technical Field

[0001] This utility model belongs to the technical field of backpack lawnmowers, specifically relating to a garden lawnmower. Background Technology

[0002] Lawn mowers are a common tool in garden maintenance. Among them, backpack lawn mowers are widely used because they allow users to move and operate them flexibly in large garden areas. The fuel tank and engine are carried on a shoulder strap, while the user holds the handles and control levers with both hands to control the mowing direction, height, and the angle and position of the mowing head.

[0003] However, with the diversification of landscape design, gardens now include not only large lawns but also numerous shrubs. When trimming shrubs, especially when the tops need to be trimmed evenly, existing backpack lawnmowers reveal significant limitations. Because shrub tops are often quite high, operators must hold the lever high for extended periods to reach the appropriate height for trimming. During this process, the operator's arms bear the weight of the lever and the mowing head for a considerable time, which is extremely physically demanding. Prolonged arm strain not only easily leads to operator fatigue and reduced efficiency but may also cause decreased precision due to exhaustion, making it impossible to ensure the neatness and consistency of the shrub top trimming, thus affecting the overall landscape quality of the garden. Utility Model Content

[0004] This utility model provides a garden lawn mower that solves the problem of excessive physical exertion caused by raising the lawn mower control lever for extended periods.

[0005] This utility model provides the following technical solution: It includes a backpack, a flexible shaft outer tube, an operating lever, a handle, and a grip. A mounting bracket is installed on the side wall of the operating lever. A turntable is rotatably connected to the inner wall of the mounting bracket. An inner groove is formed on the inner wall of the turntable. A limiting rod is slidably connected to the inner wall of the inner groove. A first limiting slot is formed on the inner wall of the mounting bracket. The limiting rod is inserted into the inner wall of the first limiting slot. A telescopic rod is provided at the bottom of the turntable. The telescopic rod includes a main tube and a sliding rod. The main tube is installed at the bottom end of the turntable. The sliding rod is slidably connected to the inner wall of the main tube. A connecting plate and a foot are installed at one end of the sliding rod. The foot is rotatably connected to one end of the connecting plate. Two casters are installed on the foot.

[0006] The limiting rod is equipped with a reset spring and a traction rope at one end. The reset spring is sleeved on the outside of the traction rope, and the traction rope is slidably connected to the inner wall of the main tube.

[0007] The main tube has a strip-shaped hole, and a slide plate is slidably connected to the inner wall of the strip-shaped hole. An outer ring is installed on the outer side of the slide plate, and the outer ring is slidably connected to the side wall of the main tube. One end of the traction rope is installed on one side of the slide plate.

[0008] The mounting bracket has a baffle plate fixedly connected to one side, the baffle plate is in contact with the side wall of the main pipe, and a second limiting slot is provided on one side of the baffle plate, and the limiting rod is inserted into the inner wall of the baffle plate.

[0009] The sliding rod has several third limiting slots on its side wall, and the inner wall of the main tube is threaded with limiting screws, which are inserted into the inner wall of the third limiting slots.

[0010] The beneficial effects of this utility model are: by supporting the operating rod with a telescopic rod, the load on the operating rod when it is raised is reduced, thus facilitating the top trimming of shrubs. This solves the problem that the operator's arm has to bear the weight of the operating rod and the mower head for a long time, which is a great test of the operator's physical strength. Prolonged arm load not only easily causes the operator to feel fatigued quickly and reduces work efficiency, but may also lead to a decrease in operating accuracy due to physical exhaustion, making it impossible to ensure the neatness and consistency of the shrub top trimming, thereby affecting the overall landscape quality of the garden.

[0011] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0018] Please see Figures 1-5 The present invention provides the following technical solution: including a backpack 1, a flexible shaft outer tube 11, an operating rod 12, a handle 121 and a grip 122. A mounting frame 2 is installed on the side wall of the operating rod 12. A turntable 21 is rotatably connected to the inner wall of the mounting frame 2. An inner groove 211 is opened on the inner wall of the turntable 21. A limiting rod 22 is slidably connected to the inner wall of the inner groove 211. A first limiting slot 23 is opened on the inner wall of the mounting frame 2. The limiting rod 22 is inserted into the inner wall of the first limiting slot 23. A telescopic rod 3 is provided at the bottom of the turntable 21. The telescopic rod 3 includes a main tube 31 and a sliding rod 32. The main tube 31 is installed at the bottom of the turntable 21. The sliding rod 32 is slidably connected to the inner wall of the main tube 31. A connecting plate 321 and a foot 33 are installed at one end of the sliding rod 32. The foot 33 is rotatably connected to one end of the connecting plate 321. Two casters 331 are installed on the foot 33.

[0019] In this implementation plan: The carrying case 1 is carried on the worker's body via a shoulder strap. The carrying case 1 contains a drive motor and an oil tank. The carrying case 1 drives the cutting component at the end of the operating rod 12 via a flexible shaft inside the flexible shaft outer tube 11 and a transmission shaft inside the operating rod 12, enabling pruning of the garden. The handle 121 and grip 122 facilitate control of the operating rod 12. The mounting frame 2 has its opening facing downwards. The upper and lower parts of the mounting frame 2 are bolted to the side wall of the operating rod 12. When pruning vegetation at specific angles or heights, the mounting frame 2 and the telescopic rod 3 can be detached from the operating rod 12. The mounting frame 2 houses and supports the turntable 21, which in turn supports the telescopic rod 3. By controlling the telescopic rod 3 to change from a parallel angle to a vertical angle at the bottom of the operating rod 12, the telescopic rod 3 can connect to the ground. The telescopic rod 3, supported by the mounting frame 2, reduces the load when the operating rod 12 is raised, thus facilitating the pruning of shrubs. The top trimming work solves the problem that the operator's arms need to bear the weight of the operating rod and the mowing head for a long time, which is a great test of the operator's physical strength. The long-term arm load can not only easily cause the operator to feel fatigued quickly and reduce work efficiency, but may also lead to a decrease in operating accuracy due to physical exhaustion, making it impossible to ensure the neatness and consistency of the top trimming of the shrubs, thus affecting the overall landscape quality of the garden. The turntable 21 accommodates the limiting rod 22 through the inner sliding groove 211. The limiting rod 22 is inserted into the first limiting slot 23, so that the telescopic rod 3 is locked in the vertical direction, ensuring the stability during operation. When moving and trimming the top of the shrubs, it moves on the ground through the foot 33 and the driving wheel 331 at the bottom of the sliding rod 32, which makes it easy for the device to follow the operator to move laterally. It is more convenient, simple and labor-saving to use. The sliding rod 32 rotates with the foot 33 through the connecting plate 321, which facilitates the turning action of the foot 33 and makes it more flexible to use.

[0020] One end of the limiting rod 22 is equipped with a return spring 221 and a traction rope 222. The return spring 221 is sleeved on the outside of the traction rope 222, and the traction rope 222 is slidably connected to the inner wall of the main tube 31. The return spring 221 pushes the limiting rod 22, making the locking of the limiting rod 22 and the first limiting slot 23 more stable. The traction rope 222 pulls the limiting rod 22 in the opposite direction, thereby unlocking the turntable 21 and the mounting bracket 2, which facilitates the angle adjustment of the telescopic rod 3.

[0021] The main pipe 31 has a strip-shaped hole 311, and a slide plate 312 is slidably connected to the inner wall of the strip-shaped hole 311. An outer ring 313 is installed on the outer side of the slide plate 312 and is slidably connected to the side wall of the main pipe 31. One end of the traction rope 222 is installed on one side of the slide plate 312. The strip-shaped hole 311 makes way for the slide plate 312, and the slide plate 312 pulls and controls the traction rope 222. The outer ring 313 facilitates the sliding adjustment of the slide plate 312 by personnel. By pulling the outer ring 313, the retraction control of the limit rod 22 is realized, thereby completing the unlocking between the mounting frame 2 and the turntable 21.

[0022] A baffle plate 24 is fixedly connected to one side of the mounting bracket 2. The baffle plate 24 contacts the side wall of the main pipe 31. A second limiting slot 241 is provided on one side of the baffle plate 24. The limiting rod 22 is inserted into the inner wall of the baffle plate 24. The mounting bracket 2 limits the main pipe 31 through the baffle plate 24 to prevent the main pipe 31 from approaching the cutting mechanism at the end of the operating rod 12. When the turntable 21 drives the telescopic rod 3 to a horizontal state, the telescopic rod 3 and the operating rod 12 are folded together. The limiting rod 22 is inserted into the second limiting slot 241 to lock it, thereby maintaining the storage stability between the telescopic rod 3 and the operating rod 12.

[0023] The sliding rod 32 has several third limiting slots 322 on its side wall. The inner wall of the main pipe 31 is threaded with limiting screws 34, which are inserted into the inner wall of the third limiting slots 322. By adjusting the combined length between the sliding rod 32 and the main pipe 31, the device can be adjusted to accommodate bushes of different heights, increasing its flexibility. After adjusting the length, tightening the limiting screws 34 allows them to be stably inserted into the third limiting slots 322, locking the main pipe 31 and the sliding rod 32 together, ensuring that the telescopic rod 3 can maintain a stable length.

[0024] The working principle and usage process of this utility model are as follows: When pruning tall vegetation such as shrubs in a garden, the sliding rod 32 is pulled out so that the length of the telescopic rod 3 matches the pruning height. Then, by tightening the limiting screw 34, the limiting screw 34 can be stably inserted into the third limiting slot 322, completing the locking between the main tube 31 and the sliding rod 32, so that the telescopic rod 3 can maintain a stable length for use. Then, the outer ring 313 is pulled to unlock the mounting bracket 2 and the turntable 21. The telescopic rod 3 is rotated to an angle perpendicular to the ground. The return spring 221 pushes the limiting insert 22 into the first limiting slot 23, so that the operating rod 12 and the telescopic rod 3 remain stable. The telescopic rod 3 supports the operating rod 12, reducing the load when the operating rod 12 is raised, thus facilitating the pruning of the top surface of the shrubs. This solves the problem that the operator's arm has to bear the weight of the operating rod and the grass cutter head for a long time, which is a great test of the operator's physical strength. Prolonged arm-loaded work can easily cause fatigue and reduce work efficiency for operators. It can also lead to decreased operational precision due to physical exhaustion, making it impossible to ensure the neatness and consistency of the shrub top trimming, thus affecting the overall landscape quality of the garden.
