Abstract
The invention relates to a high-efficiency cutting knife structure of a grass cutter. The high-efficiency cutting knife structure comprises a drive shaft, wherein a knife shaft is mounted at one end of the drive shaft, cutting blades are mounted on the 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 rings and are symmetrically arranged opposite to a center shaft of the knife shaft, and a cutting groove is formed in each of the cutting blade; inner reamers are symmetrically mounted on the outer walls of the two ends of the knife shaft, and an end reamer positioned on the outer end side of the knife shaft is mounted on each of the supporting rods. When the high-efficiency cutting knife structure 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 cutting blades provided with the cutting grooves are arranged, the cutting efficiency is improved; 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 cutting resistance is reduced, and the cutting speed is improved; as the inner reamers and the end reamers are arranged on the knife shaft, 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 efficient cutter structure of high hay mover.
The technical solution adopted in the present invention is as follows:
The efficient cutter structure of a kind of hay mover, including drive shaft, cutter shaft, cutter shaft are installed in one end of drive shaft
Upper installation cutting blade, the two ends outer wall of described cutter shaft is provided with bracing ring by support bar respectively, two bracing rings
Between be connected described cutting blade, multiple cutting blades are relative to the layout substantially symmetrical about its central axis of cutter shaft, with cutting on cutting blade
Cutter groove；
The two ends outer wall of described cutter shaft is symmetrically installed with interior reamer, support bar is provided with and is positioned at the outer side of cutter shaft
End reamer.
Further improvement as technique scheme:
Described cutting blade inclined peripheral is arranged around the central shaft of cutter shaft.
One end of described interior reamer is connected with the outer wall of cutter shaft, and the other end sticks up laterally away from the center of cutter shaft
Rise.
Described interior reamer with the angular range of cutter shaft is: 30 degree of-60 degree.
Described end reamer is drawn close to the center of cutter shaft with arcuate structure, its end.
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, efficiency is high；It is provided with the cutting blade of cutter groove, improves segmentation efficiency；Cutting blade
Cutter shaft relatively is obliquely installed, and it is once less with the contact area of weeds, thus reduces Cutting Drag, improves
Cutting speed；Interior reamer and end reamer are set on cutter shaft, reduce mowing resistance, improve cutting efficiency.
Accompanying drawing explanation
Fig. 1 is the three-dimensional structure diagram of the present invention.
Fig. 2 is another three-dimensional structure diagram of the present invention.
Fig. 3 is the front view of the present invention.
Wherein: 1, drive shaft；2, cutter shaft；3, support bar；4, bracing ring；5, cutting blade；51、
Cutter groove；6, end reamer；7, interior reamer.
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 to Figure 3, the efficient cutter structure of the hay mover of the present embodiment, including drive shaft 1,
Cutter shaft 2 is installed in one end of drive shaft 1, and cutter shaft 2 is installed cutting blade 5, and the two ends outer wall of cutter shaft 2 is respectively
Being provided with bracing ring 4 by support bar 3, be connected between two bracing rings 4 cutting blade 5, cutting blade 5 inclined peripheral
Around the layout substantially symmetrical about its central axis of cutter shaft 2, with cutter groove 51 on cutting blade 5, cutter groove 51 is by cutting blade
5 are separated into two parts so that fall into the weeds in cutter groove 51 and can continue divided, improve segmentation efficiency.
The two ends outer wall of cutter shaft 2 is symmetrically installed with interior reamer 7, one end of interior reamer 7 and the outer wall of cutter shaft 2
Being connected, the other end tilts laterally away from the center of cutter shaft 2, and interior reamer 7 with the angular range of cutter shaft 2 is:
30 degree of-60 degree.The weeds of cutter shaft 2 lateral wall circumference are cut by the interior reamer 7 tilted, and by after cutting
Weeds derive, it is to avoid its be wound around, reduce resistance.
Being provided with the end reamer 6 being positioned at the outer side of cutter shaft 2 on support bar 3, end reamer 6 is tied with arc
Structure, its end is drawn close to the center of cutter shaft 2.End reamer 6 is easy to the cutting of the weeds to cutter shaft 2 end,
Prevent end weeds from screwing in cutting blade 5.
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, efficiency is high；It is provided with the cutting blade of cutter groove, improves segmentation efficiency；Cutting blade
Cutter shaft relatively is obliquely installed, and it is once less with the contact area of weeds, thus reduces Cutting Drag, improves
Cutting speed；Interior reamer and end reamer are set on cutter shaft, reduce mowing resistance, improve cutting efficiency.
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.
