Abstract
The utility model relates to a kind of four sword flail knives of disc type, including disk, multiple blades, axial screw, nut, the blade both ends respectively open up a circular hole, the blade is rotatably arranged on disk by axial screw, axial screw one end attaching nut, the blade two sides respectively open up 2 blades, two sides totally 4 blades.The beneficial effects of the utility model are: disc type flail knife can cut off general grass; when encountering the hard object of stone one kind; has the function of certain yielding; it can be effectively protected the unlikely damage of blade, the impact kinetic energy that cutter and hard object are generated by high velocity impact can be also partially absorbed and protect cutter, mechanical connecting device, dynamic power machine not damaged or mitigate damage.Blade has four swords, can be equivalent to the use of four knives with positive and negative and u-turn installation, a knife.It is very convenient using installing, the service efficiency of cutter has been doubled up, to material is saved, has saved the energy, protection environment all has realistic meaning.
Description
Technical field
The utility model relates to grass trimmer accessory technical field, specifically a kind of four sword flail knife of disc type.
Background technique
Currently, grass trimmer, according to different mowing objects and purposes, cutter used has following form: straight knife, flail knife (steely
Matter, nylon rope matter, chain matter etc.), hobboing cutter, scissors, hang down knife etc..Respectively there are its advantage and purposes.The invention patent system is to a kind of flail knife
Improvement, improvement and expanded application.
The straight knife that grass trimmer usually configures has general delicate grass cuts off effect well.But for falling in
Thick grass in stone or when the more sturdy shrub that cannot be cut off, often will cause internecine as a result, and dynamic to output
The engine spindle of power torque generates unfavorable percussion.
Utility model content
Insufficient for the above-mentioned prior art, the utility model provides a kind of four sword flail knife of disc type.
Four sword flail knife of a kind of disc type provided by the utility model is achieved through the following technical solutions:
A kind of four sword flail knife of disc type, including disk, multiple blades, axial screw, nut, the blade both ends respectively open up
One circular hole, the blade are rotatably arranged on disk by axial screw, axial screw one end attaching nut, the knife
Piece two sides respectively open up 2 blades, two sides totally 4 blades.
Two ipsilateral edge lengths of the blade are identical.
The inclined-plane of two ipsilateral blades of the blade is opposite.
The beneficial effects of the utility model are: disc type flail knife can cut off general grass, the hard of stone one kind is being encountered
When object, have the function of certain yielding, the unlikely damage of blade can be effectively protected, can also partially absorb cutter and hard object because of high speed
The impact kinetic energy for colliding and generating protects cutter, mechanical connecting device, dynamic power machine not damaged or mitigates damage.Blade has
Four swords can be equivalent to the use of four knives with positive and negative and u-turn installation, a knife.It is very convenient using installing, double up knife
The service efficiency of tool saves the energy to material is saved, and protection environment all has realistic meaning.
Detailed description of the invention
Fig. 1 is the utility model structure diagram；
Fig. 2 is blade structure schematic diagram.
Specific embodiment
The technical solution of the utility model will be clearly and completely described by embodiment below, it is clear that described
Embodiment be only the utility model a part of the embodiment, instead of all the embodiments.Based on the reality in the utility model
Apply example, those skilled in the art's every other embodiment obtained without making creative work belongs to this
The range of utility model protection.
Four sword flail knife of a kind of disc type as depicted in figs. 1 and 2, including disk 1, multiple blades 2, axial screw 3, nut
4,2 both ends of blade respectively open up a circular hole a, and axial screw passes through circular hole a, and the blade 2 is set by the rotation of axial screw 3
It sets on disk, 3 one end attaching nut 4 of axial screw, 2 two sides of blade respectively open up 2 blade b, two sides totally 4 knives
Sword.
Further, two ipsilateral edge lengths of the blade are identical.
Further, the inclined-plane of two ipsilateral blades of the blade is opposite.
When the utility model is used, by being connect by multiple screws 5 with engine output end in the middle part of disk.Engine work
When making, disk 1 is driven to rotate, blade 2 is thrown away due to the effect of centrifugal force, and blade has mowing as general cutter
Function.
Embodiment described above only indicates the embodiments of the present invention, and the description thereof is more specific and detailed, but not
It can be interpreted as the limitation to the scope of the utility model.It should be pointed out that for those skilled in the art, not departing from
Under the premise of the utility model is conceived, various modifications and improvements can be made, these belong to scope of protection of the utility model.
