Description

Mowing line structure

The creation is related to a cutting device, in particular to a mowing line mounted on a rotatable mowing disc of a lawn mower.

A mower having a mowing line is used for fixing a part of a wire body of an appropriate length, such as flattening or screw pressing, on a rotatable mowing disc of the lawn mower. The other part of the body is exposed to the mowing tray to form a cutting portion for cutting.

Generally, the cutting portion is solid, and the cross-sectional shape is mostly quadrangular, and the outer side bending portion is formed with a cutting edge for cutting, but the angle formed by the bending between the two sides is formed. Still not sharp, the cutting force is still insufficient.

Moreover, how to increase the service life of the mowing line is also a subject of consideration by the industry.

The main purpose of this creation is to provide a mowing line structure with better cutting efficiency.

The secondary purpose of this creation is to provide a mowing line structure that has a better service life.

Another object of the present invention is to provide a mowing line structure that is lightweight.

Therefore, in order to achieve the foregoing objectives, the present invention provides a mowing line structure comprising at least one wire body having a suitable length, a portion of which is attached to a mowing mower of a lawn mower And another part is exposed to the mowing disk to form a cutting portion, the cutting portion is a hollow body or the cross-sectional outer edge shape of the cutting portion is at least three blade edges having a transverse shape like a ridge Further, the cutting portion having at least three blades arranged in an annular shape on the outer side is a hollow body, which has a better resistance structure and better cutting efficiency, and has a better service life.

Please refer to the first to fifth figures. The mowing line structure of the present invention includes at least one wire body (12), and a part thereof is fixed such as flattening or screw pressing on a lawn mower (60). One of the rotatable mowing trays (62) is exposed to the mowing tray (62) to form a cutting portion (22).

The wire body (12) is injection-molded or extruded by a plastic such as nylon or other flexible material, and the cross-sectional outer edge shape of the cutting portion (22) can be quadrangular or pentagonal (such as the second and Three figures) or hexagons (not shown), and the cutting part (22) is a hollow body, and has better resistance and service life, wherein the empty sectional shape can be set to a circular shape (such as Second and third figures), should be cut The cross-sectional outer edge shape of the cut portion (22) (such as Figures 4 and 5) or other shapes.

Referring to Figures 6 and 7, the wire body (12) is injection molded or extruded by a plastic such as nylon or other flexible material, and the cross-sectional outer edge shape of the cutting portion (22) is formed into five. The Ridge's cross-cutting edge (221) is arranged in an annular interval; the meaning of the Ridge refers to the combination of two slopes with opposite slopes or the same slope or curved slope. A ridge-like convex landform.

Wherein the bottom surface (222) of the concave portion (valley) between the five cutting edges (221), the bottom surface (222) may form a flat surface as shown in the sixth figure due to the cooling contraction in the process, or In any case, the convex surface shown in the seventh figure is formed. In any case, the focus of this creation is on the ridged blade edge arrangement and the better cutting effect.

Referring to the eighth figure, the grass cutting line structure of the present invention is disclosed, wherein the five cutting edges (221) are arranged adjacent to each other without a bottom surface, and a better cutting effect can be achieved.

Referring to the ninth and tenth drawings, the grass cutting line structure of the present invention has a cross-sectional outer edge shape of the cutting portion (22), which respectively represents six blade edges (221) arranged annularly and without a bottom surface therebetween. The annular adjacent array, wherein the tenth figure shows that the bottom surface (222) of the concave (satellite) between the six cutting edges (221) is concave.

The cutting portion (22) of the mowing line structure according to the sixth to tenth aspects of the present invention is a solid outer body. Referring to the eleventh to fifteenth drawings, the cutting portion (22) may also be hollow. The body has a better resistance structure and has better cutting efficiency, and has a better service life, wherein the hollow section shape can be set to a circular shape (such as the eleventh to fifteenth figures), corresponding to the cutting portion ( 22) Cross-sectional outer edge shape or other shape.

Please refer to the sixteenth to nineteenth, the cut of the grass line structure disclosed in the above-mentioned creation. The shape of the cross-section outer edge of the cutting portion (22) is set to seven cutting edges, and a better cutting effect can be achieved. The cutting portion (22) shown in the eighteenth and nineteenth views can also be hollow. The body has a better resistance structure and service life.

Please refer to the twentieth to twenty-third figure. The cross-sectional outer edge shape of the cutting portion (22) of the mowing line structure disclosed in the above-mentioned creation is set to three and four cutting edges respectively, and the same can be achieved. The cutting effect, wherein the cutting portion (22) shown in the twenty-first and twenty-third figures can also be set as a hollow body, and has a better resistance structure and a service life.
