Mowing blade and mower nose provided with mowing blade

Abstract

A mowing blade comprises a middle mounting part and extension parts extending to the two ends from the mounting part, wherein a cutting edge part is arranged on one side of each end extension part, and the other side of the extension part is bent and extends toward the rear upper part to form a fin part for producing exhaust air current; and each fin part comprises three wings arranged at an interval at least, the wings are formed by gradually rising and bending outward along the long direction of the blade, sharp teeth are arranged on the outer edges of the wings, the wings and the cutting edge part are arranged on the same sides of the extension parts, and gaps allowing air current to pass are arranged between adjacent wings. The invention also discloses a mower nose. The wings not only can be used for producing the air current, but also can be used for the secondary cutting of grass mowed by the cutting edge part, so that the cutting effect is improved. The gaps between the wings can also be used for holding grass stems, roots and leaves besides allowing the air current to pass, so that the grass stems, roots and leaves can be discharged in order.

Description

technical field [0001] The invention relates to a blade, which is applied to a lawnmower. The invention also relates to a lawnmower head with the blade applied thereto. Background technique [0002] At present, in the garden management, there are two forms of trimming the garden lawn: one is the reciprocating mower, which uses a reciprocating cutter like a hair clipper to cut the grass. This method is simple, but it is not easy to remove the mow This reciprocating lawn mower is suitable for cutting short coniferous lawns. It does not need to pick up the grass blades. The grass blades are scattered on the lawn and land on the ground by themselves, thus dying out naturally. The other is a rotary lawn mower, which uses a high-speed rotating mower. This type of lawn mower can not only cut coniferous grasses, but also leafy grasses, and small shrubs. Grass, the working part of this type of lawn mower is often made into a relatively closed working shield around it, and an openin...

Problems solved by technology

[0005] The blades of the above-mentioned existing rotary lawn mowers can only be used on small-leaved grasslands due to structural limitations, and the mowing effect on grasslands with small shrubs and weeds is not very good, and it is difficult to have a good and orderly discharge of grassland. leaves, resulting in poor harvesting effect
