Disclosure of Invention

The blade of the mower is provided aiming at the defects of the prior art, the cutting blade edge and the cutting sawteeth are arranged on the blade body, and the cutting blade edge cuts weeds and then cuts the weeds for multiple times through the cutting sawteeth, so that the weeds are crushed and then directly discharged to a lawn, the discharged weeds are not required to be treated with effort, and the use is convenient.

In order to achieve the above object, the present invention provides the following technical solutions.

The blade of the mower comprises a blade body, wherein the blade body comprises a central portion and cutting portions, the central portion extends towards two ends respectively, a connecting hole is formed in the central portion, a cutting edge is formed in each side edge of each cutting portion, and a cutting saw tooth is further arranged on one side, opposite to the cutting edge, of each cutting portion.

Furthermore, one side of each cutting part, which is opposite to the cutting edge, is provided with cutting sawteeth.

Furthermore, the cutting part is provided with a cutting knife edge which is folded upwards, so that the position of the cutting knife edge is higher than that of the central part.

Furthermore, the cutting part is provided with cutting sawteeth, and the cutting sawteeth are turned upwards, so that the positions of the cutting sawteeth are higher than the position of the central part.

Further, the connecting holes are asymmetric holes.

The utility model has the advantages that: the blade of the mower comprises a blade body, wherein the blade body comprises a central portion and cutting portions, the central portion extends towards two ends respectively, a connecting hole is formed in the central portion, a cutting edge is formed in each side edge of each cutting portion, and a cutting saw tooth is further arranged on one side, opposite to the cutting edge, of each cutting portion. The utility model discloses a set up the cutting edge of a knife and cutting sawtooth on the blade body, the during operation, the blade body rotates, and through the cutting edge of a knife with weeds cutting back, weeds after the cutting are carried out a lot of cutting by the cutting sawtooth again to smash weeds, directly discharge to the lawn with weeds after smashing again on, need not to spend effort and handle discharged weeds, convenient to use, weeds after smashing moreover can also regard as the fertilizer on lawn.
