Description

Technical Field

[0001] This utility model relates to the field of lawnmower technology, and in particular to a lawnmower blade. Background Technology

[0002] Currently, backpack lawnmower blades on the market fall into three categories: metal serrated blades, plastic blades, and trimmer heads equipped with trimming ropes. When using a trimmer head, the trimming rope needs to be wound around it, and the high-speed rotation of the head cuts the weeds through the rope. However, the current winding method for the trimming rope is quite complex, and the rope's high stiffness makes it difficult for workers to wind. Each time the rope needs to be replaced, it takes a considerable amount of time for workers to wind it back onto the trimmer head, affecting the lawnmower's cutting efficiency. Summary of the Invention

Detailed Implementation

[0029] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0030] First, combine Figures 1-5 This invention describes a lawnmower blade according to an embodiment of the present invention, used for fixing a mowing rope.

[0031] like Figures 1-5 As shown, a lawnmower blade of this utility model embodiment is used to fix the mowing rope, including: blade assembly 1 and fixing assembly 2;

[0032] The cutter head assembly 1 includes: a cutter head body 11 and a reinforcing mechanism 12;

[0033] The reinforcing mechanism 12 is provided on the blade body 11. The reinforcing mechanism 12 is used to increase the structural strength of the blade body 11. The blade body 11 is used to connect with the lawnmower. The fixing component 2 is provided on the blade body 11.

[0034] The fixing component 2 includes: a rope threading component 21 and a positioning plate 22;

[0035] The rope threading component 21 is fixed to the cutter head body 11. The rope threading component 21 has a positioning groove and at least two rope threading holes. The rope threading holes are located on the outer side wall of the rope threading component 21 and connect the positioning groove to the outside. The positioning plate 22 is located in the positioning groove and between the two rope threading holes. The positioning plate 22 is used to position the grass cutting rope that passes through the two rope threading holes.

[0036] This application first passes one end of the mowing rope through a rope hole, and then passes the same end of the mowing rope through another rope hole. The lengths of both ends of the mowing rope are adjusted to make them the same. At the same time, both ends of the mowing rope are pulled so that the part of the mowing rope located in the positioning groove is stuck between the inner wall of the positioning groove and the positioning plate 22. This allows the mowing rope to be quickly wound around the mower blade, saving the time of the mower blade winding the mowing rope and improving the mowing efficiency of the mower.

[0037] like Figures 2-5As shown, the blade body 11 has a connecting part 13 and a fixing part 14. The fixing part 14 is located on the outside of the connecting part 13. The connecting part 13 is used to connect with a lawnmower. The rope threading part 21 is located on the fixing part 14.

[0038] The connecting part 13 is cylindrical, and the top surface of the connecting part 13 is flat. A connecting hole is provided on the top surface of the connecting part 13 for connecting with a lawnmower. The cross-sectional diameter of the connecting part 13 gradually increases from top to bottom.

[0039] The fixing part 14 is sleeved on the outside of the connecting part 13, and the fixing part 14 includes: an inclined end and a horizontal end;

[0040] The inner end of the inclined end is connected to the bottom end of the connecting part 13. The inclined end is inclined to the outside. One end of the horizontal end is connected to the outer end of the inclined end. The rope threading part 21 is located on the horizontal end.

[0041] The shape design of the connecting part 13 and the fixing part 14 makes the rotation of the blade body 11 more stable when the mower drives the blade head to rotate, thus ensuring the mowing effect of the mowing rope.

[0042] like Figures 2-5 As shown, the reinforcing mechanism 12 includes: a first reinforcing part 15 and a second reinforcing part 16;

[0043] The first reinforcing part 15 is provided on the connecting part 13, and the second reinforcing part 16 is provided on the fixing part 14 and the connecting part 13.

[0044] The first reinforcing part 15 is characterized in that it includes: a first reinforcing plate;

[0045] The first reinforcing plate is located inside the connecting part 13, and the first reinforcing plates are arranged at equal intervals around the connecting holes on the connecting part 13.

[0046] The second reinforcing part 16 includes: a second reinforcing plate;

[0047] The second reinforcing plate is located on the outside of the connecting part 13. The second reinforcing plate is fixed on the connecting part 13 and the fixing part 14. The second reinforcing plates are arranged at equal intervals around the top surface of the connecting part 13.

[0048] The structural strength of the blade body 11 is improved by the reinforcing mechanism 12, so as to avoid damage to the blade body 11 when cutting grass. The first and second reinforcing plates, which are circumferentially equidistant, can improve the structural strength while ensuring the stability of the rotation of the blade body 11.

[0049] like Figures 4-5 As shown, the bottom of the positioning groove of the rope threading component 21 is provided with an arc-shaped guide plate, which is used to guide the direction of the grass cutting rope passing through the rope threading hole.

[0050] The fixing component 2 includes a reinforcing side plate 23; the reinforcing side plate 23 is disposed on the cutter head body 11 and is located on both sides of the rope threading component 21.

[0051] The curved guide plate directs the mowing rope through the rope hole to the top of the positioning groove, facilitating the worker's next threading. The reinforced side plate 23 enhances the structural strength of the rope threading component 21, preventing damage during mowing.

[0052] Above, refer to Figures 1-5 This application describes a lawnmower cutter head according to an embodiment of the present invention. First, one end of the cutting rope is passed through a rope-passing hole, and then the same end of the cutting rope is passed through another rope-passing hole. The lengths of both ends of the cutting rope are adjusted to make them equal. Simultaneously, both ends of the cutting rope are pulled, causing the portion of the cutting rope located in the positioning groove to be engaged between the inner wall of the positioning groove and the positioning plate 22. This allows the cutting rope to be quickly wound around the lawnmower cutter head, saving time and improving the cutting efficiency of the lawnmower.
