Description

Technical Field

[0001] This utility model relates to the technical field of lawn mowing, and in particular to a lawn trimming shear. Background Technology

[0002] Lawns are typically laid out in unpaved areas of gardens or playgrounds to enhance the environment. However, as the grass grows, it often needs to be mowed regularly. When using a lawnmower, the large size of the machine makes it difficult to reach the edges and corners of the lawn, affecting its overall appearance.

[0003] Existing lawn trimmers mainly use high-speed motors or diesel engines to drive the cutting discs or wires to rotate and break up the grass at high speed. Most lawn mowers are horizontal blades. Bermuda grass has a strong ability to grow horizontally. When the horizontal grass stems extend to the top of the hard paving, the horizontal blades cannot cut and trim them, and manual cutting is often required, which is time-consuming and labor-intensive.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1 like Figures 1 to 6 As shown, this embodiment provides a lawn trimmer, including a grip 1, a fixed blade 2, a movable blade 3, and a drive mechanism. The grip 1 is equipped with a drive mechanism and a controller 13. The lower end of the grip 1 is fixedly connected to the fixed blade 2 and hinged to the movable blade 3. One end of the movable blade 3 matches the fixed blade 2 in the vertical plane, and the other end is connected to the drive mechanism. The drive mechanism enables the movable blade 3 to swing relative to the fixed blade 2 to achieve an opening and closing action. The drive mechanism is communicatively connected to the controller 13. This embodiment achieves the trimming of horizontal grass branches in the lawn by matching the movable blade 3 with the fixed blade 2 in the vertical plane. The operation is convenient and quick, and the trimming is neat and beautiful.

[0024] As an optional solution, in this embodiment, the driving mechanism is a winch, the rope 9 on the winch is connected to the end of the movable shear 3, and the gripping part 1 is provided with a sliding sleeve for the rope 9 to limit its movement.

[0025] As an optional solution, in this embodiment, the winch includes a motor 8, a bevel gear 10, and a winch 11. A bevel gear 10 is connected to the shaft of the winch 11 and the shaft of the motor 8, respectively. The bevel gears 10 mesh and drive each other. A rope 9 is wound on the winch 11. Through the reciprocating motion of the motor 8, the rope 9 is driven to pull the movable shear blade 3, causing it to swing, thereby achieving the trimming of grass blades.

[0026] As an optional solution, in this embodiment, the rope 9 is a steel wire rope, and the motor 8 and bevel gear 10 are both located inside the grip 1. The motor 8 is communicatively connected to the controller 13. In this embodiment, the winch 11 is also located inside the grip 1, which facilitates integration and overall mechanical lightweighting. Wear-resistant pads can be provided at the contact points between the steel wire rope and the outer shell. The battery compartment is located near 2 / 3 of the grip, and the battery compartment contains the battery 10, which is used to provide power to the motor 8. This saves space and avoids the loss of equipment balance due to the battery 10, which would increase the difficulty of one-handed operation. In other words, this design can achieve one-handed operation.

[0027] As an optional solution, in this embodiment, the grip part 1 is an inclined grip rod. The top of the grip rod is the handle area, and the bottom is provided with two connecting pieces. The two connecting pieces are respectively connected (hinged) to the fixed scissor 2 and the movable scissor 3. The controller 13 is located in the handle area for easy manual control.

[0028] As an optional solution, in this embodiment, the movable shearing blade 3 includes an integrally formed blade and a swing arm, which are V-shaped with an included angle of 100°-170°.

[0029] As an alternative, in this embodiment, the middle part of the movable scissor 3 is hinged to the gripping part 1, and an elastic element 4 is provided between the swing arm and the gripping part 1. The elastic element 4 can open the blade relative to the fixed scissor 2. The elastic element 4 is preferably a spring, which can push the swing arm to return to its original position, causing the blade to open.

[0030] As an optional solution, in this embodiment, the blade of the movable shearing blade 3 is provided below the blade, and the fixed shearing blade 2 includes a vertical limiting plate 5 and a receiving platform 6. The receiving platform 6 is provided above the vertical limiting plate 5. The receiving platform 6 receives the blade and grass leaves. The blade of the movable shearing blade 3 can also form a staggered upper and lower shearing structure with the vertical limiting plate 5. At the same time, the receiving platform 6 can be attached to the curb or paving bricks for positioning, so as to stabilize the trimming line.

[0031] As an optional solution, in this embodiment, a pair of rollers 7 are movably connected to one side of the vertical limiting plate 5. The rollers 7 are used to move on the top surface of the steps. A vertical waist-shaped hole is provided on the vertical limiting plate 5. The central axis of the roller 7 passes through the waist-shaped hole and is connected to the locking nut. It can adapt to curbs and paving bricks of different heights. The roller 7 can easily slide and follow the shape of the curb and stone to complete the lawn trimming. The receiving platform 6 is set horizontally and extends outward from the fixed shearing blade 2 to form a horizontal limit. If the overall height difference between the lawn and the curb or stone is very small, or if the soil surface is flush with the curb, the roller 7 can be removed, allowing the vertical limiting plate 5 to be inserted into the brick joint. The limiting plate protruding from one side of the receiving platform 6 slides close to the curb or stone for height positioning. Among them, the roller 7 can ensure that the blade is close to the curb or paving during the trimming process and moves with its edge line, ensuring a stable and straight trimming line.

[0032] As an optional solution, in this embodiment, the vertical limiting plate 5 is provided with a protrusion lower than the roller 7. The vertical limiting plate 5 is used to conform to the side of the step for guidance. By limiting the edge, the trimming accuracy is improved, the operation is convenient, and labor is saved.
