By adopting the scheme, the first cutting edge can be used for cutting common shrubs, when the large shrubs need to be cut, the direction of the blade is changed, the blade is cut by the bevel edge, the bevel edge has a guiding effect when the bevel edge is used for cutting, the stress is not vertical stress during cutting, and the vibration is smaller when the large shrubs are cut.

Preferably, the two cutting edges are located on the same plane of the blade.

By adopting the scheme, the cutting edge is positioned on the same plane of the blade, so that the cutting edge is convenient to process.

Preferably, the two second cutting edges are both positioned on a plane of the blade away from the cutting edges.

By adopting the scheme, the two cutting edges are positioned on the same plane of the blade, and the two cutting edges are convenient to process.

Preferably, the oblique side is rounded.

By adopting the scheme, the bevel edge is arc-shaped, the arc-shaped guiding effect is optimal, when large shrubs are cut, the brush cutter vibrates less, and the damage of the brush cutter to hands is greatly reduced.

Preferably, the oblique edges are obliquely transited from the cutting section away from the blade to the end of the blade away from the mounting section.

By adopting the scheme, the length of the bevel edge is longer when the bevel edge is inclined to one side of the cutting section away from the installation section, and the efficiency is higher when shrubs are cut.

Preferably, the bevel edge is provided with a saw-toothed section.

By adopting the scheme, the sawtooth section arranged on the bevel edge has higher cutting efficiency when cutting large shrubs.

The utility model discloses owing to adopted above technical scheme, have apparent technological effect: the first cutting edge and the second cutting edge are respectively located on two planes, the processing is more convenient, the first cutting edge can be used for cutting common shrubs, when large shrubs need to be cut, the blade is changed in direction, the bevel edge is used for cutting on one side, the bevel edge is arc-shaped, the arc-shaped guiding effect is optimal, when the bevel edge is used for cutting, the stress direction of the second cutting edge of the blade is not vertical stress when the blade is used for cutting, the vibration of the second cutting edge is smaller when the blade is used for cutting large shrubs, and the injury of the brush cutter to the hands of an operator is greatly reduced.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

The first embodiment is as follows:

referring to fig. 1 and 2, a brush cutter blade comprises a mounting section 1 for mounting and cutting sections 2 positioned on two sides of the mounting section 1, a mounting hole 3 for mounting is formed in the center of the mounting section 1, a first cutting edge 4 is respectively arranged on one side edge of the cutting section 2 along the length direction, the first cutting edges 4 are arranged in opposite directions relative to the blade, the first cutting edges 4 are positioned on the same plane of the blade, when the blade rotates around the center of the mounting hole 3, the first cutting edges 4 rotate towards one direction, two inclined edges 5 are respectively arranged on the two cutting sections 2, the inclined edges 5 are obliquely transited from one side of the cutting section 2 far from the first cutting edges 4 to one side of the cutting section 2 far from the mounting section 1, the first cutting edges 4 are far from one end of the mounting section 1, the two inclined edges 5 are arranged in opposite directions relative to the blade, the arc-shaped inclined edges 5 are circular arc-shaped, and two cutting edges 6 are arranged, the second blades 6 of the two end cutting sections 2 are positioned on the same plane.

Example two:

referring to fig. 3 and 4, the difference between this embodiment and the first embodiment is that in this embodiment, the oblique edge 5 is completely transited from the side of the cutting section 2 away from the blade-4 to the end of the blade-4 away from the mounting section 1 by inclining, so as to increase the length of the blade-4 and improve the cutting efficiency.

Example three:

referring to fig. 5, the present embodiment is different from the first embodiment in that the oblique side 5 in the present embodiment is linear.

Example four:

referring to fig. 6, the present embodiment is different from the second embodiment in that the second embodiment has a second blade 6 and a saw tooth section 7 with a saw tooth shape on the oblique edge 5, and the saw tooth section 7 is located on the side of the oblique edge 5 facing the first blade 4.
