Abstract
The invention relates to a cutting knife component for a grass cutter. The cutting knife component comprises cutting blades mounted on a knife shaft; a supporting ring is mounted on the outer wall of each of the two ends of the knife shaft by means of supporting rods, the cutting blades are fixedly connected between the two supporting rods, are symmetrically arranged opposite to a center shaft of the knife shaft and are obliquely arranged opposite to the center shaft of the knife shaft, and a plurality of cutting teeth are arranged on each of the cutting blade. When the cutting knife component works, an engine drives the knife shaft to rotate at a high speed; when in rolling, the cutting blades perform continuous cutting on weeds, so that the effect is good, and the efficiency is high; as the plurality of cutting teeth are arranged to cut weeds, the long weeds are prevented from winding the cutting blades, so that the resistance is reduced; as the cutting blades are obliquely arranged opposite to the knife shaft, the one-time contact areas between the cutting blades and the weeds are smaller, so that the grass cutting resistance is reduced, and the cutting efficiency is improved.
Description
Technical field
The present invention relates to technical field of agricultural machinery, especially a kind of hand-held rotary cultivator.
Background technology
Hay mover be a kind of for cutting the grass on a lawn, the machine tool of vegetation etc., it be by cutterhead, electromotor,
Road wheel, walking mechanism, blade, handrail, control part form.Cutterhead is contained on live axle, cutterhead
On equipped with electromotor, equipped with blade on the output shaft of electromotor, blade utilizes the high speed rotating of electromotor to carry out
Mowing and operate, its speed is fast, save the activity duration, decrease substantial amounts of human resources.
In existing hay mover, the design of the structure of its hay knife is not reasonable, mow inefficient, blade is easy
Damage.
Summary of the invention
The applicant is for the above-mentioned medium shortcoming of existing production technology, it is provided that a kind of rational in infrastructure, work efficiency
The cutter assembly of high hay mover.
The technical solution adopted in the present invention is as follows:
The cutter assembly of a kind of hay mover, including the cutting blade being installed on cutter shaft, outside the two ends of described cutter shaft
Wall is provided with bracing ring by support bar respectively, and be connected between two bracing rings described cutting blade, multiple cutting blade phases
Layout substantially symmetrical about its central axis to cutter shaft, cutting blade relative to cutter shaft inclined arrange, on cutting blade with
Multiple cutting teeths.
Further improvement as technique scheme:
The cross section of described cutting teeth is triangle.
Described cutting blade includes four pieces.
Beneficial effects of the present invention is as follows:
When the present invention works, driven by engine cutter shaft high speed rotating, weeds are carried out when rolling continuously by cutting blade
Cutting, it is effective；Multiple cutting teeth structure is set, weeds are cut, it is to avoid long weeds are wound around and cut
Blade, reduces resistance；Cutting blade is obliquely installed relative to cutter shaft, and it is once less with the contact area of weeds,
Thus reduce Cutting Drag, improve cutting speed.
Accompanying drawing explanation
Fig. 1 is the three-dimensional structure diagram of the present invention.
Fig. 2 is the front view of the present invention.
Wherein: 1, cutter shaft；2, bracing ring；3, support bar；4, cutting blade；41, cutting teeth.
Detailed description of the invention
Below in conjunction with the accompanying drawings, the detailed description of the invention of the present invention is described.
As shown in Figure 1 and Figure 2, the cutter assembly of the hay mover of the present embodiment, including being installed on cutter shaft 1
Cutting blade 4, the two ends outer wall of cutter shaft 1 is provided with bracing ring 2, two bracing rings 2 by support bar 3 respectively
Between be connected cutting blade 4, cutting blade 4 includes the layout substantially symmetrical about its central axis of four pieces and relative cutter shafts 1, cutting blade
The inclined of 4 relative cutter shafts 1 is arranged, i.e. cutting blade 4 entirety is connected to bracing ring in encircling shape structure
On 2；For improving cutter dynamics and efficiency, with multiple cutting teeths 41 on cutting blade 4, cutting teeth 41
Cross section is triangle.
When the present invention works, driven by engine cutter shaft high speed rotating, weeds are carried out when rolling continuously by cutting blade
Cutting, it is effective；Multiple cutting teeth structure is set, weeds are cut, it is to avoid long weeds are wound around and cut
Blade, reduces resistance；Cutting blade is obliquely installed relative to cutter shaft, and it is once less with the contact area of weeds,
Thus reduce Cutting Drag, improve cutting speed.
Above description is explanation of the invention, is not the restriction to invention, and limited range of the present invention is joined
See claim, within protection scope of the present invention, any type of amendment can be made.
