Description

Rotary cutter for mower

Technical Field

The utility model relates to the field of mower cutters, in particular to a rotary cutter for a mower.

Background

The mower is also called a weeding machine, a grass mower, a lawn trimmer and the like, is a mechanical tool for trimming lawns, vegetation and the like, and has a cart type and a hand type;

in its handheld lawn mower, when using, rotary blade high-speed rotation, the blade does not adopt metal blade, adopts materials such as plastics, can cut the grass when rotating at a high speed, does not adopt metal blade can produce danger when preventing to splash, and its cutter structure is single, generally just nylon plastic strip etc. can not adjust the cutting scope of cutter, and when plane cutting, cutting radius can improve efficiency greatly, when vertical cutting, like road both sides gap department, and rotary radius just obstructs the cutting greatly, and flexibility is not good when the adjustable cutting.

Disclosure of Invention

Aiming at the problems in the prior art, the utility model aims to provide the rotary cutter for the mower, which can enable the cutter bar to be bent, fastened and fixed by arranging the fastening component on the inner side of the cutter bar, can bend and adjust the rotating radius of the cutter bar, adjusts the rotating cutting range, is convenient to adjust and use, and is flexible and convenient to cut and use.

In order to solve the problems, the utility model adopts the following technical scheme.

The utility model provides a rotary cutter for lawn mower, includes the lawn mower, the lower extreme drive shaft department external surface fixation of lawn mower has the supporting ring, the both ends of supporting ring are provided with the sword strip, one side of sword strip is fixed with the supporting shoe, the supporting shoe surface sets up the lug, the inboard fixed surface of sword strip has the buckling seat, the convex buckling hole is seted up on the surface of buckling seat, through setting up the lock joint subassembly in the sword strip inboard, can make the crooked lock joint of sword strip fixed, can bend the radius of rotation of adjusting the sword strip, adjusts the scope of rotatory cutting, and the regulation is used conveniently, and is nimble convenient when cutting is used.

Further, the supporting ring and the knife bar are made of nylon materials.

Further, the lower end of the driving shaft is provided with a protruding shaft, and the supporting ring is sleeved outside the protruding shaft.

Further, the outer surface of the protruding shaft is connected with a nut through threads.

Further, the cross section of the cutter bar is of a triangular structure.

Further, the buckling seats are uniformly distributed on the inner side surface of the cutter bar.

Further, the length of the knife bar is twenty centimeters.

Compared with the prior art, the utility model has the advantages that:

(1) Through setting up the lock joint subassembly in the blade inboard, can make the crooked lock joint of blade fixed, but the radius of rotation of bending regulation blade, adjust the scope of rotatory cutting, convenient to adjust and use, nimble convenience when cutting the use.
