Description

Mower blade Technical Field The utility model relates to a mower, in particular to a mower blade. Background Mower is widely applied to garden maintenance, agriculture and public greening as mechanical equipment, and the core function of mower depends on efficient cutting of vegetation by blade design. Conventional mower blades mostly adopt flat metal blades, and cutting is achieved through rotation or reciprocating motion. However, as user requirements for mowing efficiency, safety, and environmental compatibility continue to increase, existing blade designs increasingly expose the following technical drawbacks: 1. Poor durability and impact resistance When the flat blade encounters hard objects (such as stones and tree roots), impact force is concentrated on the edge or fixed point of the blade, and the blade is easy to curl, crack or integrally deform. Meanwhile, the continuous friction between the blade and the ground and the grass stem accelerates passivation of the cutting edge, frequent replacement or polishing is needed, and maintenance cost is increased. 2. Insufficient cutting efficiency and quality Traditional flat blades rely on simple rotational kinetic energy to cut grass blades, and lack effective utilization of air flow. In the operation process, stable ascending air flow cannot be formed when the blade rotates, so that grass blades are overwhelmed instead of cut vertically, and the cutting effect on lodging grass or soft vegetation is poor. In addition, the cutting angle of the straight blade is single, repeated mowing or missed mowing is easy to cause uneven lawn surface, and the lawn needs to be reworked for multiple times. Disclosure of Invention The utility model aims to solve the technical problem of providing the mower blade which is simple and compact in structure, high in strength, good in impact resistance effect and good in mowing effect. The present utility model provides a mower blade comprising: a base 11 as a mounting carrier, wherein a mounting hole 110 is formed in the base 11; The blade body is formed by outwards extending the end part of the base part 11, the edge of the blade body is provided with a cutting edge, the end part of the blade body is upwards bent to form a first connecting part 12, the end part of the first connecting part 12 is reversely bent to form a first blade body 13, the end part of the first blade body 13 is downwards bent to form a second connecting part 14, and the end part of the second connecting part 14 is reversely bent to form a second blade body 15; The tilted portion 16 is formed by bending the rear end and/or the end portion of the second blade body 15 obliquely upward. Further, the first cutter body 13 is parallel to the length direction of the second cutter body 15. Further, the plane of the first connecting portion 12 and/or the second connecting portion 14 is inclined to the base portion 11. Further, the length of the blade side of the first blade body 13 is greater than the length of the back side of the first blade body 13. Further, the level of the blade side of the first blade body 13 is higher than the level of the back side of the first blade body 13. Further, the included angle between the plane of the first cutter body 13 and the rotation direction of the cutter body is greater than or equal to 1 degree and less than or equal to 10 degrees. Further, the level of the blade side of the second blade body 15 is lower than the level of the back side of the second blade body 15. Further, the included angle between the plane of the second cutter body 15 and the rotation direction of the cutter body is greater than or equal to 1 degree and less than or equal to 10 degrees. Further, the tilting portion 16 is bent upward in an arc shape around a bending line, and the length direction of the bending line is inclined to the length direction of the second cutter body 15. Further, an included angle between the tilting portion 16 and the second cutter body 15 is greater than or equal to 10 degrees and less than or equal to 45 degrees. Further, the length of the second cutter body 15 is greater than or equal to the length of the first cutter body 13. The mower blade can improve the overall structural strength of the blade by bending to form two cutter bodies positioned on different planes, avoid the risks of edge rolling, chipping or overall deformation when encountering hard objects, reduce the relative length of the cutter edge relative to the plane where each cutter body is positioned on different planes, improve the cutting force, facilitate the cutting of harder grass stems, simultaneously realize alternate cutting of two sections of cutter edges, improve the mowing efficiency, realize high mowing efficiency and good effect, and simultaneously, the tilting part structure can improve the overall structural strength of the blade, generate upward air flow in the high-speed rotating process, guide the grass stems to stand towards the cutter edg
