Description

Technical Field

[0001] The present invention relates to the technical field of grass trimmer equipment, and in particular to a grass trimmer with a shock absorbing function and a shock absorbing method. Background Art

[0002] A lawn mower, also known as a lawn mower or weed cutter, is a garden tool used to trim lawns and remove weeds. It helps maintain the beauty and tidiness of lawns by using rotating blades or nylon ropes (in some models) to cut grass and other vegetation. There are three main types of lawn mowers: manual, electric and fuel-powered. The working principle of the electric lawn mower is that the motor is powered by a power supply, and the coil inside the motor generates a magnetic field. When the power is turned on, the current passes through the coil, and the generated magnetic field interacts with the permanent magnet in the motor, driving the rotor in the motor to rotate, and the rotor drives the axial coupling in the motor to rotate. A blade is installed on the coupling. As the rotor rotates, the blade also rotates, thereby cutting the grass and trees on the lawn. In the process of maintaining the beauty and tidiness of the lawn, the lawn mower is an indispensable tool. Its efficiency and stability are directly related to the work effect and operational safety. However, it is worth noting that when the generator of the lawn mower shakes during operation, this vibration will often be transmitted to the entire equipment, causing the lawn mower to shake unstablely as a whole.

7. The grass trimmer with shock absorption function according to claim 1, Features: The upper and lower ends of the shock absorber (75) are respectively hinged to the first V-shaped seat (72) and the second V-shaped seat (74); a circular plate (76) is fixedly provided on the side of the fixed seat (73); the other end of the circular plate (76) is connected to the bearing of the wheel (77).

8. A grass trimmer with a shock absorbing function according to claim 7, Features: Telescopic rods (78) are hingedly provided at both left and right ends of the lower end of the shock absorber (75), and a rotating rod is hingedly provided at the other end of the telescopic rod (78). The rotating rod is sleeved at the center of the fixed seat (73) and connected to the bearing of the fixed seat (73).

9. The grass trimmer with shock absorption function according to claim 1, Features: A plurality of placement buckets (8) are fixedly mounted on the top surface of the mower body (1); the plurality of placement buckets (8) are evenly distributed around the top surface of the mower body (1); counterweight blocks are arranged inside the placement buckets (8); and the number of counterweight blocks inside each placement bucket (8) is different.

10. A method for reducing shock of a lawn mower with a shock-absorbing function, Features: Includes the following: S1: At the beginning of the start-up process, the operator places different numbers of counterweights in a plurality of placement buckets (8) to adjust the center of gravity of the machine, thereby improving the stability of the machine and reducing vibration; S2: When the generator (67) is installed, the threaded rod (69) is rotated to drive the movable frame (68) to move downward, so that the movable frame (68) and the placement frame (66) are respectively in contact with the upper and lower ends of the generator (67). The movable frame (68) and the placement frame (66) position the generator (67) to reduce unnecessary friction and collision, thereby reducing the source of vibration and reducing the shaking amplitude of the generator (67). When the generator (67) is running, since the upper and lower ends of the generator (67) are positioned, the generator (67) can only shake forward and backward. When the generator (67) shakes, it drives the limit frame (610) and the damping rod (617) to move. The damping rod (617) and the spring on the damping rod (617) reduce the vibration of the second ventilation plate (620). At the same time, the sound-absorbing cotton (615) absorbs the sound generated by the vibration of the generator (67) to reduce the noise of the generator (67); S3: After confirming that the generator (67) is started, the mowing roller (51) is powered, and the mowing roller (51) starts to work, pushing the push handle (4) to drive the device to move. A rubber sleeve (53) is provided at the connection between the mowing roller (51) and the connecting plate (52). The rubber sleeve (53) can quickly restore its deformation when the mowing roller (51) is impacted, absorb and disperse vibration energy, and a support roller (54) is installed at the right end of the connecting plate (52) to increase the support area of ​​the device and improve the overall stability of the device. Hydraulic rods (57) are installed on both sides of the support roller (54) to disperse the vibration of the support roller (54); S4: When the push handle (4) drives the device to move on an uneven road surface, the first V-shaped seat (72) and the second V-shaped seat (74) drive the fixed seat (73) to move, and the fixed seat (73) drives the circular plate (76) and the wheel (77) to move in a vertical direction, thereby ensuring that the grass trimmer body (1) can move smoothly, and the shock absorber (75) can absorb and disperse vibration, thereby reducing the vibration transmitted to the operator and other parts of the machine.
