Abstract

Provided is a cutting blade of a mower. The cutting blade comprises a cutting blade body in the shape of a long strip. Two cutting edges, in proximity to the end portion of the cutting blade body, are arranged in a central symmetry manner. The end portions, opposite to end corners of side edges of the cutting edges, of the cutting blade body bend towards the direction away from the cutting blade body in order to from bending parts. Each bending part has an arc-shaped bending surface and is tangent to the cutting blade body in a transitional mode in order to form a tangent line. The connecting line for the center of the cutting blade body and pointed ends of the cutting edges runs parallel to the tangent line. When the cutting blade body of the mower rotatably works, the bending part drives the air to generate additional turbulent flow moving from the position below the cutting blade body to the upward part such that upper ends of grass mowed rapidly enter a cutting region of the mower under the suction effect of turbulent flow. As a result, the cutting blade of the mower performs cutting operation. Accordingly, grass needed to be cut can be rapidly sucked into the cutting region of the mower in order to finish pruning operation. The advance speed of the mower is improved. The cutting blade of the mower has advantages such as large turbulent flow for suction, smoother cutting and fine quality of broken grass.

Description

technical field [0001] The invention relates to the technical field of lawn treatment machinery, in particular to a lawnmower cutting blade. Background technique [0002] With the development of society and economy, people's environmental awareness is getting stronger and stronger, and a large number of lawns and grasslands have entered our daily life. A lawn mower is a semi-automatic mechanical tool for cutting grass, vegetation, etc., trimming weeds and treating flat green lawns. Lawn mowers are widely used because they are easy to operate and save manpower and time. For example, they can be used for lawn trimming and weed removal in parks, green belts, factory grass, golf courses and other places. [0003] The cutting blade of the lawn mower is the core component of the lawn mower, and the cutting speed and cutting efficiency of the lawn mower are related to the structure of the cutting blade of the lawn mower. At present, the cutting blades of lawn mowers on the market...
