Description
Technical field
The present invention relates to a kind of grass-mowing machine, more particularly to a kind of grass-mowing machine with dismountable shield.
Background technology
In prior art, in order to prevent grass-mowing machine, the debris such as grass cuttings splash when in use, on the work head of grass-mowing machine all
Meeting mounting strap, is directed to debris away from the side of user by shield, the centrifugal force produced by the rotation of the head that works
Debris are thrown away into user, it is ensured that the safety of user；As long-time is contacted with debris, shield needs periodic cleaning, because
This shield needs to be designed to dismountable annexation with work head, so will result in a problem：General shield is all logical
Cross the relation of being rigidly connected and work head be connected, it is this no matter how accurate to be rigidly connected, must be apertured, and work head
Have when beating the grass it is very strong rock, this gap of long duration can be increasing, until shield loosens, causes potential safety hazard；
There is a kind of technical scheme to be shield to be fastened on work head by screw, but after work head work a period of time, screw
Still inevitably loosen, need commonly used other instruments of user to tighten screw, increased the burden of user,
User can also produce certain potential safety hazard also it is easy to forget that tighten.
The content of the invention
It is an object of the invention to provide a kind of grass-mowing machine, the grass-mowing machine can be such that shield hardly produces when the head that works is beaten the grass
Life is rocked, and significantly reduces potential safety hazard.
In order to overcome the defect of prior art, the invention provides a kind of grass-mowing machine, including fuselage, it is fixed on the fuselage
The detachably connected shield of the work head with function of beating the grass of one end and the work, the work head are provided with company
Joint, the shield are provided with the link slot that can be engaged with the union joint, and the union joint is detachably inserted to institute
State in link slot, the side wall of the link slot is provided with and the union joint can be pressed on the elastic component in the link slot.
Preferably, the elastic component is symmetrically disposed on the side wall of the link slot both sides.
It is further preferred that the elastic component is metal clips, offer on the shield with the link slot by connecting
The mounting groove that logical portion is connected, the metal clips are fixed in the mounting groove by securing member, are had on the metal clips
There is the bossing that the elastic-restoring force perpendicular to the link slot bearing of trend can be provided, the bossing is by described
Interconnecting part is extended in the link slot.
It is further preferred that the metal clips is L shapes, the bossing is at the knuckle of L shapes.
It is further preferred that the securing member is screw.
Connection between work head and shield is changed into being flexible coupling by grass-mowing machine of the present invention by elastic component, and elastic component is absorbed
The position deviation that work head and shield are operationally produced, enables each part smooth working, and shield will not be because of loosening and work
Make head disengaging, reduce potential safety hazard；This mounting means need not additionally use other instruments simultaneously, bring to user
It is convenient.

Specific embodiment
Below in conjunction with the accompanying drawings the preferred implementation of grass-mowing machine of the present invention is described in detail.
Referring to accompanying drawing 1-5, grass-mowing machine of the present invention includes fuselage 1, and fuselage 1 is generally elongated rod shape, and its one end is provided with work
2, work 2 mainly is made up of with element of beating the grass motor, shield 3 with work 2 detachably connected, specifically,
Work 2 is provided with union joint 21, and link slot 31 is provided with shield 3, and union joint 21 can be plugged in link slot 31,
Elastic component 32 is provided with the side wall of link slot 31, the elastic component 32 can be pressed on union joint 21 in link slot 31.
Tool
For body, the mounting groove 34 that can accommodate elastic component 32, mounting groove 34 and link slot are offered on shield 3
Connected by an interconnecting part between 31, there is bossing, when elastic component 32 is housed in mounting groove 34 on elastic component 32
When, bossing is extended in link slot 31, in the present embodiment by above-mentioned interconnecting part, and elastic component 32 is by union joint 21
Apply the power perpendicular to 31 bearing of trend of link slot, head clamping will be connected, realize the connection of shield 3 and work 2.
Used as a preferred version, elastic component 32 can be symmetrical arranged in the both sides of link slot 31, and for example left and right respectively sets
Put an identical elastic component 32 so that it is two power in opposite direction equal in magnitude to be applied on union joint 21, so press from both sides
Tight effect is more preferable；Meanwhile, elastic component 32 uses metal clips, such as, with steel disc after bending, shape is L-shaped, L shapes
It is exactly above-mentioned bossing at knuckle, the bossing is extended to by the interconnecting part between mounting groove 34 and link slot 31
In link slot 31, when in the insertion link slot 31 of union joint 21, will contact with the bossing.
In order that elastic component 32 preferably can be fixed in mounting groove 34, used in the present embodiment, securing member 33 will
Elastic component 32 is pressed in mounting groove 34, specifically, and as elastic component 32 employs metal clips, therefore securing member 33 is adopted
With screw, some pads on screw, can be arranged, so when metal clips is housed in mounting groove 34, screw is together with pad
Piece pushes down metal clips from top to bottom, so, even if work 2 is operationally generated rocking, due to screw not with work
2 directly contacts, therefore loosening will not be produced, such user additionally need not carry screwdriver etc. when using grass-mowing machine
Instrument is in case loosened screw.
When grass-mowing machine works, work 2 is generated rocks, but as union joint 21 is in close contact with elastic component 32,
Work 2 position deviation for rocking generation are absorbed by elastic component 32, therefore gap, work will not be produced after working long hours
Work is between 2 and shield 3 still in close-connected state.
The present invention compared to prior art, by the elasticity of elastic component 32 sponge between work 2 and shield 3 because
The position deviation rocked and produce so that the structure connection of whole grass-mowing machine is compact, and shield 3 will not be loose long because of use time
Dynamic, while the mounting means of this union joint-link slot is more convenient, user does not need any instrument just complete to install,
Both the burden of user had been alleviated, potential safety hazard had been also eliminated.
Above-described embodiment technology design only to illustrate the invention and feature, its object is to allow person skilled in the art
Scholar will appreciate that present disclosure and implement according to this, can not be limited the scope of the invention with this, all according to the present invention
Equivalence changes or modification that spirit is made, should all be included within the scope of the present invention.
