Preferably, the left and right sides in the portion of beating the grass are formed with the cutting edge of outer thin interior thickness, the sawtooth is molded over this
On cutting edge.For the cutting edge of this zigzag fashion compared with straight cutting edge, cutting line is longer, and has bending angle, does not allow when in use
It is also easy to produce and allows careless phenomenon, improve mowing efficiency.
Preferably, the cross section of the cutting edge is in isosceles triangle shape, i.e., cutting edge ecto-entad is respectively towards upper and lower two
Direction progressive additive.This cutting edge is easy to process, and the blade with the cutting edge is when in use, is more uniformly stressed, does not allow
Easily passivation is mowed more efficient.
Preferably, the outer edge of the cutting edge is towards the mounting portion direction gradually inclined bevel edge in two sides to the left and right;?
Just refer to that the width self installation portion between the cutting edge of the portion two sides of beating the grass of blade becomes narrow gradually outward.
Preferably, bevel edge of the sawtooth towards mounting portion side is the arc-shaped side being inwardly recessed.With arc-shaped
The sawtooth of bevel edge, the structure setting for not only increasing the length of cutting edge, and being inwardly recessed can be carried out more effectively hugging grass, kept away
Exempt to allow careless phenomenon.
Preferably, being provided with mounting hole on the mounting portion.
Preferably, the mounting hole is hardy hole, the central axes of the hardy hole are overlapped with the center line of knife ontology, and big
Hole portion is compared to small hole portion closer to the portion of beating the grass.Cucurbit hole machined is more convenient, and blade integrated molding is also more easier, and drops significantly
Low production cost.
The utility model solves technical solution used by second technical problem are as follows: a kind of cutterhead, including turntable, it is described
The periphery of turntable is equipped at least two fixation holes to the fixation blade;The fixation hole passes through connector and the blade
Mounting hole connection.
Preferably, the connector is the connecting column being anchored in fixation hole, which is equipped with and the hardy hole
The compatible groove of small hole portion, which manifests the surface of turntable, and the big hole portion of hardy hole is passed through for connecting column, hardy hole
Small hole portion then to be caught in groove.
Further preferably, the two sides of the fixation hole are additionally provided with the abutment to limit the blade rotation.This is kept out
Part is caught in cutterhead when can prevent blade in use by larger resistance, causes equipment fault.
Compared with prior art, the utility model provides a kind of integrally formed blades for mower, and this blade is easy
Processing and lower production costs;The two sides of the blade form the cutting edge comprising multiple sawtooth, especially in preferred embodiment
In, bevel edge of the sawtooth towards mounting portion side is the arc-shaped side being inwardly recessed, the sawtooth with this arc-shaped bevel edge,
The cutting edge for not only increasing the length of cutting edge, and being inwardly recessed can more effectively carry out hugging grass, avoid allowing careless phenomenon, significantly
Improve mowing efficiency.Cutterhead described in the utility model is attached by connecting column and the blade with hardy hole, this
Kind connection type makes the installation of blades for mower, disassembly simpler, saves the replacing construction of blade, also correspondingly improves
The efficiency of beating the grass of grass-mowing machine.
Detailed description of the invention
Fig. 1 is the schematic perspective view of the blade of the utility model embodiment;
Fig. 2 is the cross-sectional view of the blade of the utility model embodiment;
Fig. 3 is the schematic perspective view of the cutterhead of the utility model embodiment;
Fig. 4 is the cross-sectional view and partial structurtes exploded view of the cutterhead of the utility model embodiment.
Specific embodiment
The utility model is described in further detail below in conjunction with figure embodiment.
As shown in FIG. 1 to FIG. 2, a kind of blades for mower, including knife ontology 1, knife ontology 1 have mounting portion 2 and portion of beating the grass
