[0023] In the following, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present invention. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0024] The embodiments of the present invention will be described in detail below with reference to the drawings.

[0025] As Figures 1-4 shown, an embodiment of the present invention provides a double - edge mowing blade, including an anti - entanglement grass component 101, a main body component 201 and a mounting rod 30;

[0026] The anti - entanglement grass component 101 includes a first anti - entanglement grass blade 10, a second anti - entanglement grass blade 11, an edge groove 12 and a first mounting hole 13;

[0027] The bottoms of a plurality of second anti - entanglement grass blades 11 are all mounted on the top of the first anti - entanglement grass blade 10. The edge groove 12 is opened on one side of the second anti - entanglement grass blade 11, and the first mounting hole 13 is opened on the top of the first anti - entanglement grass blade 10.

[0028] In one embodiment, the included angle between the first anti - entanglement grass blade 10 and the second anti - entanglement grass blade 11 is 90 degrees. Through the settings of the first anti - entanglement grass blade 10 and the second anti - entanglement grass blade 11, the weeds cut by the double - edge blade 21 are further shredded by the first anti - entanglement grass blade 10 and the second anti - entanglement grass blade 11, avoiding the phenomenon that the weeds are wound around the mounting rod 30, which leads to a decrease in the machine speed and an increase in the heating speed, thereby improving the working efficiency. Through the setting of the edge groove 12, the strength of the second anti - entanglement grass blade 11 is increased, and the efficiency of chip removal treatment is improved.

[0029] In one embodiment, the main body assembly 201 includes a base body 20, a double-edge blade 21, a fixing bolt 22, a drag reduction hole 23, a second mounting hole 24, and a through hole 25; the bottom of the first anti-entangling grass blade 10 is mounted on the bottom of the base body 20, one side of the double-edge blade 21 is mounted on one side of the base body 20 through the fixing bolt 22, the drag reduction hole 23 is opened at the top of the base body 20, the shape of the drag reduction hole 23 is a water droplet shape, the second mounting hole 24 is opened at the top of the base body 20, the through hole 25 is opened at the top of the base body 20, and the layout of the drag reduction holes 23 is arranged in ascending order from the center outwards. By providing the drag reduction holes 23, while reducing the weight of the device itself, the air resistance during cutting is reduced, and the working difficulty of the staff is reduced.

[0030] In one embodiment, both the first anti-entangling grass blade 10 and the base body 20 are mounted on the outer side wall of the mounting rod 30. By providing the mounting rod 30, the first anti-entangling grass blade 10 and the base body 20 are fixed.

[0031] When the present utility model is working: First, the double-edge blade 21 is clamped on the base body 20, and then the double-edge blade 21 is fixed on the base body 20 through the fixing bolt 22. When the double-edge blade 21 needs to be replaced, only the fixing bolt 22 needs to be loosened, and the double-edge blade 21 can be removed from the base body 20, so as to facilitate the staff to replace the blade. Then, both the first anti-entangling grass blade 10 and the base body 20 are mounted on the outer side wall of the mounting rod 30. During use, by providing the drag reduction holes 23, while reducing the weight of the device itself, the air resistance during cutting is reduced, and the working difficulty of the staff is reduced. The weeds cut by the double-edge blade 21 are further shredded by the first anti-entangling grass blade 10 and the second anti-entangling grass blade 11, avoiding the phenomenon that the weeds are wound around the mounting rod 30, resulting in a decrease in the machine speed and an increase in the heating rate, thereby improving the working efficiency.
