Description

Technical Field

[0001] The present invention relates to the technical field of lawn mower equipment, and particularly relates to a lawn mower with a shock absorption function and a shock absorption method. Background Art

[0002] A lawn mower, also known as a grass cutter or weeding machine, is a gardening tool used for trimming lawns and removing weeds. It cuts grass and other vegetation by using a rotating blade or nylon string (in some models), thereby helping to maintain the beauty and neatness of the lawn. Lawn mowers are mainly divided into three types: manual, electric, and fuel-powered.

[0003] Among them, the working principle of an electric lawn mower is that the electric motor provides power by connecting to a power source. A coil inside the electric motor generates a magnetic field. When powered on, an electric current passes through the coil, and the generated magnetic field interacts with the permanent magnet in the electric motor to drive the rotor in the electric motor to rotate. The rotor drives the axial coupling in the electric motor to rotate. A blade is installed on the coupling. As the rotor rotates, the blade also rotates accordingly, thereby cutting the grass and vegetation on the lawn.

[0004] In the process of maintaining the beauty and neatness of the lawn, as an indispensable tool, the efficiency and stability of the lawn mower are directly related to the operation effect and operation safety. However, it is worth noting that when the generator of the lawn mower shakes during operation, this vibration often transmits to the entire device, resulting in an unstable shaking phenomenon of the whole lawn mower. Summary of the Invention

[0005] The purpose of this part is to outline some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this part, as well as in the abstract and title of the specification of this application, to avoid obscuring the purpose of this part, the abstract, and the title.

Connecting rods are fixedly arranged on both the front and rear side surfaces of the support roller. The other ends of the connecting rods penetrate through and are rotatably connected to the adjacent connecting plate. A blocking plate is fixedly sleeved on the outer side surface of the connecting rod. There are two blocking plates arranged front and rear. The front and rear blocking plates are located on both sides of the connecting plate. A hydraulic rod is arranged on the other side of the connecting plate. The hydraulic rod is rotatably connected to the connecting rod. The other end of the hydraulic rod is hinged to the lawn mower main body.

The other end of a support rod hinged on the side surface of the positioning plate is located inside the moving groove and is slidably connected with the inner wall of the moving groove. A sound-absorbing cotton is fixedly arranged between the positioning plate and the moving plate. The sound-absorbing cotton absorbs the sound generated when the generator vibrates, reducing the noise of the generator.

[0016] Preferably, fixing rods are arranged at both the upper and lower ends of the moving plate. A damping rod is fixedly arranged between the fixing rod and the first ventilation plate. The two ends of the fixing rod are hinged with a handle rod. The other end of the handle rod is provided with a positioning frame.

The rotating rod is sleeved on the center of the fixing seat and is rotationally connected with the fixing seat through a bearing. The shock absorber can absorb and disperse vibrations, reducing the vibrations transmitted to the operator and other parts of the machine.

[0019] Preferably, a plurality of placement hoppers are fixedly installed on the top surface of the lawn mower main body. The plurality of placement hoppers are evenly distributed around the top surface of the lawn mower main body. Counterweight blocks are arranged inside the placement hoppers. The number of counterweight blocks in each placement hopper is different. Different numbers of counterweight blocks are respectively placed in the plurality of placement hoppers to adjust the center of gravity position of the machine, improving the stability of the machine and reducing vibrations.

[0020] A shock-absorbing method for a lawn mower with shock-absorbing function, the steps are as follows:

[0021] S1: At the beginning of the startup process, the operator places different numbers of counterweight blocks in multiple placement hoppers respectively, adjusts the center of gravity position of the machine, improves the stability of the machine and reduces vibration;

[0022] S2: When installing the generator, rotate the threaded rod to drive the moving frame to move downward, so that the moving frame and the placement frame are respectively in contact with the upper and lower ends of the generator. The moving frame and the placement frame position the generator, reduce unnecessary friction and collision, thereby reducing the source of vibration generation, reducing the swaying amplitude of the generator. When the generator is running, due to the positioning of the upper and lower ends of the generator, the generator can only sway back and forth. When the generator sways, it drives the limit frame and the damping rod to move. The damping rod and the spring on the damping rod reduce the vibration received by the second ventilation plate. At the same time, the sound-absorbing cotton absorbs the sound generated when the generator vibrates, and reduces the noise of the generator;

[0023] S3: After confirming that the generator is started, power is supplied to the mowing roller, and the mowing roller starts to work. Push the push handle to drive the device to move. There is a rubber sleeve at the connection between the mowing roller and the connecting plate. The rubber sleeve can quickly recover its deformation when the mowing roller is impacted, absorb and disperse the vibration energy. A support roller is installed at the right end of the connecting plate to increase the support area of the device, improve the overall stability of the device, and hydraulic rods are installed on both sides of the support roller to disperse the vibration received by the support roller;

[0024] S4: When the push handle drives the device to move on an uneven road surface, the first V-shaped seat and the second V-shaped seat drive the fixed seat to move, and the fixed seat drives the circular plate and the wheel to be able to move in the vertical direction, ensuring that the main body of the lawn mower can move smoothly. The shock absorber can absorb and disperse vibration, and reduce the vibration transmitted to the operator and other parts of the machine.

[0025] The beneficial effects of the present invention:

[0026] (1) In the present invention, by rotating the threaded rod to drive the moving frame to move downward, the moving frame and the placement frame are respectively in contact with the upper and lower ends of the generator.

[0027] (2) In the present invention, when the generator sways, it drives the limit frame and the damping rod to move. The damping rod and the spring on the damping rod reduce the vibration received by the second ventilation plate, reduce the swaying amplitude of the generator. At the same time, the sound-absorbing cotton absorbs the sound generated when the generator vibrates, and reduces the noise of the generator, achieving the effect of reducing the noise of the generator.

[0028] (3) In the present invention, a rubber sleeve is provided at the connection between the mowing roller and the connecting plate. The rubber sleeve can quickly recover its deformation when the mowing roller is impacted, absorb and disperse the vibration energy. A support roller is installed at the right end of the connecting plate to increase the support area of the device. Hydraulic rods are installed on both sides of the support roller to disperse the vibration received by the support roller, achieving the effect of improving the stability of the device.

[0029] (4) In the present invention, the first V-shaped seat and the second V-shaped seat drive the fixed seat to move. The fixed seat drives the circular plate and the wheels to move in the vertical direction, ensuring that the main body of the lawn mower can move smoothly.
