Description
Technical field
The present invention relates to mower art fields, especially design a kind of protective cover.
Background technology
Grass trimmer be it is a kind of for cutting the grass on a lawn, the machine tool of the green vegetations such as weeds, it includes driving motor, operation
Bar, cutter head, blade achieve the purpose that cut the grass on a lawn using the high speed rotation that driving motor provides, it can improve the labor of labourer
Efficiency of movement and reduction labor intensity, but the weeds meeting splashes cut during trimming, high-speed rotating blade exist
If fracture occurs in the course of work to fly out under effect of inertia, easily the body of operator is caused to seriously endanger, in existing skill
In art, accident occurs in order to prevent, a protective cover can be installed on grass trimmer, be fixed in operating lever, fan-shaped protective cover is only
It can prevent weeds from splashing, there is no any safeguard procedures, disc protective cover energy disposition but waste material in the top of cutter head
Material, and it is inconvenient, need user to dismantle when in use.
Invention content
It is an object of the invention to provide a kind of simple in structure, angle adjustable, the high grass cutter protection caps of safety coefficient.
In order to solve the above technical problems, the technical scheme is that：A kind of protective roof structure of grass trimmer, including be in round
The master shield of shape and side shield in semi-cylindrical, are equipped with mounting base on main file plate, and above-mentioned is used in fan-shaped master shield
It blocks the weeds splashed upwards, and is used for blocking damaging because encountering the hard object such as small stone in the side shield of semi-cylindrical and fly out
Blade, which is to protect the safety of user, and material, above-mentioned mounting base are saved again relative to disc protective cover
It is equipped with an angle adjusting mechanism, the angle adjusting mechanism can be adjusted according to the demand of user relative to fixed operating lever
The angle of operation sense.
In above-mentioned protective cover, mounting base is equipped with bolt hole, and operating lever is bolted on bolt in mounting base
The position in hole.
In above-mentioned protective cover, the angle of regulation range of the bolt connecting mechanism in mounting base is between 30 °~80 °.
In above-mentioned protective cover, mounting hole is provided on master shield, operating lever may pass through master shield and completely include cutter head
Inside.
In above-mentioned protective cover, master shield is equipped with mounting hole, is located at center.
In above-mentioned protective cover, mounting base is integral type with master shield, and structural strength is high.
In above-mentioned protective cover, master shield and side shield are all made of transparent plastic material, and quality is lighter, and user can
Intuitively to see the working order of tool bit part in the case where not removing protective cover.
Description of the drawings
Fig. 1 is a kind of protective roof structure schematic diagram of grass trimmer of the present invention.
Fig. 2 is a kind of protective cover vertical view of grass trimmer of the present invention.
Fig. 3 is the angle adjusting mechanism schematic diagram of the present invention.
Figure label：1, cover body 2, master shield 3, mounting base 4, mounting hole 5, bolt hole 6, side shield 7, operating lever 8, cutter head

Beneficial effects of the present invention：The combination of master shield and side shield more fully ensure that the safety of user, main gear
Plate and side shield are all made of transparent plastic material, and quality is lighter, and user can be intuitive in the case where not removing cover body
See the working order of tool bit part.
Compared with prior art, it is the advantages of this protective cover：Reliable not easily to fall off, the structural strength of installation section fastening
Height, operating lever are set including mounting hole can completely include tool bit part using angle adjustable master shield, are effectively prevented miscellaneous
It is careless to splash upwards.Side shield can prevent the blade of fracture from flying out, simple in structure, and the transparent plastic material of material selection uses
Person can be subjective the service condition for judging blade, also avoid the hard object under blades impact to weeds.
Specific implementation mode
With reference to the accompanying drawings of the specification, the present invention is described in more detail.
A kind of protective cover of grass trimmer as shown in Figure 1, 2, including cover body 1, above-mentioned cover body include rounded master shield
