[0019] The following describes the specific implementation of the present utility model in detail with reference to specific embodiments.

[0020] As Figures 1 to 3 shown, a kind of anti-entangling and environment-friendly grass cutting blade provided by an embodiment of the present utility model includes the main body of the grass cutting blade 1, the mounting hole 11 integrally formed with the middle part of the main body of the grass cutting blade 1 of the main body of the grass cutting blade 1, and further includes:

[0021] The secondary blade unit 2, multiple groups of the secondary blade units 2 are arranged in a ring shape in the middle of the mowing blade main body 1. The secondary blade unit 2 is integrally formed with the mowing blade main body 1. The secondary blade unit 2 includes a secondary blade 3 formed by cutting and bending the mowing blade main body 1. The secondary blade unit 2 further includes a sound-absorbing groove 4 formed by the cut gap.

[0022] The primary blade unit 5, multiple groups of the primary blade units 5 are arranged in a ring shape on the outer edge of the mowing blade main body 1. The primary blade unit 5 includes a primary blade 6 for cutting. A chip groove 7 is fixedly arranged on one side of the primary blade 6. A cutter head 8 is also welded inside the primary blade 6. A cutter head groove 61 is arranged at the position corresponding to the cutter head 8 on the primary blade 6.

[0023] In an embodiment of the present invention, through the provided secondary blade 3, it can be used to cut the grass that has been wound around the device. By setting the secondary blade 3 as a helically bent structure, when the mowing blade rotates at a high speed, a certain lifting force can also be generated to offset a part of the gravity of the mowing blade. By setting the mowing blade main body 1 as a disk-shaped structure with a thin middle part, the self-weight of the mowing blade is reduced. Cooperating with the provided retaining ring 12, the grass can be pressed down, reducing the contact friction between the grass stem and the surface of the mowing blade, playing a certain anti-winding effect, and reducing the useless work loss of the motor, achieving the effect of energy conservation and environmental protection.

[0024] As Figure 3 shown, as a preferred embodiment of the present invention, the mowing blade main body 1 is set as a disk-shaped structure with a thin center and a thick outer side.

[0025] Furthermore, a retaining ring 12 integrally formed with the mowing blade main body 1 is also arranged on one side of the mowing blade main body 1. The retaining ring 12 is set as a ring-shaped structure with a semi-circular cross-section.

[0026] In an example of the present invention, cooperating with the provided retaining ring 12, the grass can be pressed down, reducing the contact friction between the grass stem and the surface of the mowing blade, playing a certain anti-winding effect, and reducing the useless work loss of the motor, achieving the effect of energy conservation and environmental protection.

[0027] As Figures 1 to 2 shown, as a preferred embodiment of the present invention, the secondary blade 3 is set as a blade-shaped structure with a helical bend. The sound-absorbing groove 4 is similar to the overall shape of the secondary blade 3. An auxiliary hole 41 is fixedly arranged at the intersection of the sound-absorbing groove 4 and the secondary blade 3. The auxiliary hole 41 is set as a circular through hole.

[0028] In an example of the present utility model, by setting the secondary blade 3 to a helically bent structure, when the mowing blade rotates at a high speed, a certain lifting force can also be generated to offset a part of the gravity of the mowing blade, which can reduce the motor loss. Through the provided auxiliary hole 41, it is convenient for the bending process of the secondary blade 3, reducing the deformation damage at the folding angle and improving the service life of the mowing blade. In addition, the sound absorption groove 4 can also be used as a sound absorption hole to reduce the noise during operation and improve the comfort of the operator.

[0029] As a preferred embodiment of the present utility model, the cutter head 8 is made of a high-hardness wear-resistant material, and the thickness of the cutter head 8 is greater than that of the main blade 6.

[0030] In an example of the present utility model, through the cutter head 8 welded in the cutter head groove 61, during operation, the cutter head 8 serves as the main worn area. By setting the cutter head 8 to a high-hardness wear-resistant material, on the one hand, it can improve the sharpness of the mowing blade, and on the other hand, it can improve the service life. Setting the thickness of the cutter head 8 to be greater than that of the main blade 6 can reduce the friction on the main blade 6 during cutting, thereby reducing the wear of the main blade 6.
