The blade fast-changing mechanism of the grass cutting machine comprises blades and a blade disc, wherein the side faces of the blade disc are provided with blade guide grooves which are mutually communicated, and foot buckling guide grooves which are mutually communicated are arranged on upper ends of the blade guide grooves. The upper portion of the blade disc is provided with two symmetrical locating tables, and two symmetrical foot buckling locating tables are arranged on the inner side of the blade disc. The middle portion of each blade is provided with a first foot buckle and a second foot buckle. The blades are installed inside the blade guide grooves, and the first foot buckle and the second foot buckle are arranged tightly close to the foot buckling locating tables. The blade fast-changing mechanism of the grass cutting machine has the advantages of being simple, compact and reasonable in structure, capable of quickly and conveniently changing the blades on the grass cutting machine, capable of bringing convenience to people, and capable of increasing working efficiency.
Description
Technical field
The utility model relates to a kind of blades for mower quick-changing mechanism, specifically is used for the blade on the quick and convenient replacing mower, belongs to the electric tool technical field.
Background technology
At present, mower cuts general employing plastic blade to vegetation.Plastic knife sector-meeting fracture or wearing and tearing in long-term use procedure cause losing efficacy.After the former because blade of fracture was run into hard thing, the elasticity of itself was inadequate, causes fracture.The main cause of wearing and tearing is that the wearability of blade is inadequate, in use serious wear.Therefore, the service life of the blades for mower that uses at present is shorter, need to often change.The mechanism that designs a kind of quick-replaceable blades for mower just seems very important.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of blades for mower quick-changing mechanism is provided, and can change quickly and easily the blade on the mower, has brought convenience to people, has improved operating efficiency.
According to the technical scheme that the utility model provides, the blades for mower quick-changing mechanism comprises blade and cutterhead, it is characterized in that: the cutterhead side is provided with the blade gathering sill of perforation, and what blade gathering sill upper end was provided with perforation buckles the pin gathering sill.Described cutterhead upper end is provided with the positioning table of two symmetries, and what the cutterhead inboard was provided with two symmetries buckles the pin positioning table.Blade middle part is provided with first and buckles pin and second and buckle pin.Described blade is installed in the blade gathering sill, and the first button pin and the second button pin are near button pin positioning table.
The cross section of described blade gathering sill is wide at the top and narrow at the bottom trapezoidal.
The cross sectional shape of described blade is corresponding with blade gathering sill cross sectional shape.
Described the first button pin one end is connected with blade, is provided with the gap between the first button other three ends of pin and the blade, and the first button pin upper surface is a level and smooth inclined-plane.
Described the second button pin is identical with the first button leg structure, and symmetrical.
Described button pin gathering sill is communicated with the blade gathering sill.
Described positioning table tightly suppresses blade.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Can change quickly and easily the blade on the mower, bring convenience to people; Improved operating efficiency.

Embodiment
Following the utility model is further described in connection with the embodiment in the accompanying drawing:
Shown in Fig. 1 ~ 2, the utility model comprises blade 1 and cutterhead 2, and cutterhead 2 sides are provided with the blade gathering sill 5 of perforation, and the cross section of blade gathering sill 5 is wide at the top and narrow at the bottom trapezoidal, and is anti-loaded when the design of trapezoid cross section has avoided blade 1 to install.What described blade gathering sill 5 upper ends were provided with perforation buckles pin gathering sill 6, and button pin gathering sill 6 is communicated with blade gathering sill 5.Described cutterhead 2 upper ends are provided with the positioning table 7 of two symmetries, and what cutterhead 2 inboards were provided with two symmetries buckles pin positioning table 8.
The cross sectional shape of blade 1 is corresponding with blade gathering sill 5 cross sectional shapes.Described blade 1 middle part is provided with first and buckles pin 3 and second and buckle pin 4.Described the first button pin 3 one ends are connected with blade 1, are provided with the gap between the first button pin 3 other three ends and the blade 1, and the first button pin 3 upper surfaces are a level and smooth inclined-plane.Described the second button pin 4 is identical with the first button pin 3 structures, and symmetrical.
Described blade 1 is installed in the blade gathering sill 5, and positioning table 7 tightly suppresses blade 1, so that blade 1 location is more reliable, avoids the axial runout of blade 1.The first button pin 3 and the second button pin 4 are near button pin positioning table 8, so that blade 1 can't circular runout.
The utility model buckle blade 1, first first pin 3 and is pushed blade gathering sill 5, buckle in the pin gathering sill 6 in when work, and first detains pin 3 compressive deformations so that blade 1, first is buckled pin 3 can pass through blade gathering sill 5, buckle among the pin gathering sill 6 insertion cutterheads 2.When blade 1 during in the suitable installation site of cutterhead 2 interior arrival, the first button pin 3 and the second button pin 4 respectively near cutterhead 2 inboards buckle pin positioning table 8, the radial position of blade 1 is stuck.Simultaneously, positioning table 7 is stuck with the axial location of blade 1, avoids blade 1 that axial runout occurs.At this moment, blade 1 and cutterhead 2 are finished installation, when blade 1 damage needs to change, only need depress the first button pin 3 or second and detain pin 4, and pulling blade 1 breaks away from cutterhead 2.Installation and removal are all very easy to be quick.
