Technical Field

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

[0002] A lawnmower is a mechanical tool used for trimming lawns, vegetation, etc. Its high-speed engine output greatly increases output speed, saving lawnmower workers' time and reducing manpower. However, current lawnmowers still have some problems. When operating a lawnmower, while completing the mowing task, it is essential to effectively avoid damage to seedlings and hard objects such as stones. In existing lawnmowers, there is a gap between the main blade and the protective cover. This causes the lawnmower to become entangled in weeds during operation, increasing the load on the main blade components, reducing its speed, or even preventing it from rotating, thus affecting work efficiency and shortening the lawnmower's lifespan.

[0003] Therefore, there is an urgent need for a lawnmower accessory that can avoid damage to seedlings and hard objects such as stones, and effectively prevent weeds from getting tangled, so as to improve the working efficiency and service life of lawnmowers. Utility Model Content

[0004] This utility model provides a lawnmower protector that is lightweight, inexpensive, easy to operate, and can avoid damage to seedlings and hard objects such as stones, effectively prevent weeds from getting tangled, and extend the service life of the lawnmower.

[0005] The technical solution adopted by this utility model is: a protector for a lawnmower, including a protective ring and an anti-tangle cover, wherein the protective ring is detachably connected to the working head, the anti-tangle cover is detachably connected to the working head, and the anti-tangle cover is located between the protective ring and the main blade head.

[0006] With the above technical solution, when encountering seedlings or stones, the protective ring can effectively avoid hard objects such as seedlings or stones. The anti-tangling cover is located between the protective ring and the main blade head, which can effectively prevent weeds from tangling. The structure is simple, the operation is easy, and the working efficiency and service life of the lawnmower are improved.

[0007] As a further improvement of this utility model, the axial height of the anti-winding cover is adapted to the axial height of the operating gap between the protective ring and the main cutter head.

[0008] Through the above technical solution, the anti-tangle cover fills the operating gap between the protective ring and the main blade head, and more effectively prevents weeds from getting tangled.

[0009] As a further improvement of this utility model, the axial height of the anti-winding cover is equal to the axial height of the operating gap between the protective ring and the main cutter head.

[0010] Through the above technical solutions, the anti-tangle cover achieves the optimal filling operation gap effect, which can better prevent weeds from getting tangled.

[0011] As a further improvement of this utility model, the protective ring is provided with a fixing part at its center, the body of the fixing part forms a first groove, the body of the anti-winding cover forms a second groove corresponding to the first groove, the edge of the protective ring is provided with a frame, the outer periphery of the frame extends beyond the outer periphery of the main blade, and a plurality of support parts are provided between the fixing part and the frame.

[0012] The above technical solution can avoid stones and seedlings, protect the main blade, and has a simple structure and is easy to operate.

[0013] As a further improvement of this utility model, the protective ring is provided with a blade, and the orientation of the blade is at a non-zero angle with the rotation plane of the main blade head.

[0014] The above technical solution can effectively utilize the blade to cut tangled weeds.

[0015] As a further improvement of this utility model, the protective ring is provided with a mounting part for mounting the blade.

[0016] The above technical solution facilitates the installation of the blade onto the protective ring.

[0017] As a further improvement of this utility model, the blade is vertically arranged in the mounting part.

[0018] With the above technical solution, the blade is vertically fixed to the mounting part so that the blade can cut weeds and prevent weeds from getting tangled.

[0019] As a further improvement of this utility model, the blade is inclinedly disposed on the mounting portion.

[0020] With the above technical solution, the blade is tilted and fixed to the mounting part so that the blade can slide and cut weeds, which can better prevent weeds from getting tangled again.

[0021] As a further improvement of this utility model, the mounting part is an elongated through groove extending radially along the support part; the blade includes a mounting end and a cutting part; the cutting part passes through the elongated through groove, and the mounting end overlaps the support part and covers at least a portion of the opening of the elongated through groove.

[0022] The above technical solution facilitates the installation of the blade onto the support.

[0023] As a further improvement of this utility model, the cross-section of the first groove is circular, and the cross-section of the second groove is also circular.

[0024] With the above technical solution, when foreign objects such as grass and vines come into contact with this smooth curved surface, they have nowhere to "grab" and are not easily hooked or wrapped around it. In contrast, grooves with sharp edges (such as square or trapezoidal shapes) are more likely to trap and accumulate weeds. Attached Figure Description
