Description

Lawn trimmer

Technical field

The utility model is related to graden machine, and in particular to a kind of lawn trimmer.

Background technology

Lawn trimmer is used for the trimming that side is carried out to the grass on lawn border or plant.Deburring body of the prior art Product is huge, it is impossible to dismantle, not readily transportable and storage.Because cutter is non-adjustable relative to the distance on ground, when apart from ground too When near, easily there is the situation that barrier breaks cutter, simultaneously because cutter can not be adjusted or adjusted relative to the height on ground Section is very inconvenient, after blade is used long, the edge-neatening efffct that can not have been obtained due to the change of working depth.In addition, existing Trimmer in technology is in deburring operation, and the broken grass cut disorderly flies, the use of healthy and equipment in itself to operator Life-span brings hidden danger.

The content of the invention

The purpose of this utility model be to provide it is a kind of can conveniently in regulation cutter ground height, while again light and handy and real With laborsaving easy to disassemble, and will not occur in operation the lawn trimmer of the random winged phenomenon of broken grass.

To realize that the technical scheme that the purpose of this utility model is used is：A kind of lawn trimmer, including chassis, the bottom of with Handrail, the engine on chassis and the front wheels and rear wheels of disk connection；It is characterized in that：Knife is installed in the side on chassis Box, the cutter in knife box is fixed on one end of rotating shaft, and the power by reducing gear and engine of the rotating shaft other end is defeated Go out connection；The installation axle of the front-wheel is connected by adjustable rotary pivoted arm with chassis, and by adjustable rotary pivoted arm, regulation is fixed on Height of the knife cassette bottom portion far from ground of chassis side.

The utility model is obvious due to the good effect taken said structure and produced：I.e.

1. because distance of the knife box away from ground is adjustable, deburring height can be adjusted, except obtaining more preferable edge-neatening efffct, Cutting-tool's used life can be extended.

2. compact integral structure is light and handy, except being easy to dismounting to store, using also very dexterous.

3rd, due to the structure of knife box, the horizontal winged phenomenon of broken grass never occurs in operation.

Specific embodiment

Referring to accompanying drawing, the lawn trimmer in figure, including chassis 2, the handrail 1 being connected with chassis 2, on chassis Engine 3 and front-wheel 6 and trailing wheel 5；It is characterized in that：Knife box 4 is installed in the side on chassis, the cutter 7 in knife box is fixed In one end of rotating shaft 8, the power output by reducing gear and engine of the rotating shaft other end is connected；The installation axle of the front-wheel 10b is connected by adjustable rotary pivoted arm 10 with chassis, and by adjustable rotary pivoted arm 10, regulation is fixed on the knife box 4 of chassis side Height of the bottom far from ground.

Further, the knife box 4 is top and is a part of open of closing, bottom and outside close to the one side of engine Arc cavity.The structure ensure that broken grass upwards or will not think that engine side is flown upward.

The rotating shaft 8 is supported by bearing 4a by bearing holder (housing, cover) 4b, and bearing holder (housing, cover) 4b is arranged on knife box by spacing fixed plate 4c On.

The reducing gear includes deceleration belt pulley or gear 9, by output of the deceleration belt pulley by belt and engine Belt wheel connects special delivery power；Or transmission power is engaged with the output shaft gear of engine by reduction gearing.

Further, the installation axle 10b of the front-wheel is fixed on the off-centered one end of adjustable rotary pivoted arm 10, adjustable The mounting hole site on turning arm 10 and chassis 2 is in the off-centered other end of adjustable rotary pivoted arm；Adjustable rotary pivoted arm 10 passes through lock Tight screw is fixed through mounting hole with chassis.

Preferably, being set with lock screw can drive what adjustable rotary pivoted arm rotated by center of rotation of lock screw There is hook on regulation handle 10a, the regulation handle 10a, can mount, realize with the spacing hole being arranged on the connecting plate of chassis The postrotational positioning of adjustable rotary pivoted arm 10.When needing regulation knife box height, regulation handle is outwards moved, hook thereon is taken off From spacing hole, regulation handle is moved forward or backward, while being raised and lowered front-wheel, also makes knife box and cutter away from ground Level Change.

Preferably, the handrail is divided into after handrail lower end is connected to two by engaging lug 1a under handrail 1c and lower handrail 1b On chassis between wheel；The upper end of lower handrail and the lower end of handrail are connected；In junction, pass through removable butterfly nut 1e It is fixed.The very convenient dismounting of handrail, storage does not also take up space

The controlling switch 1d of the above-mentioned setting engine on handrail.Make manipulation very convenient.

Further, connecting plate 2a is vertically arranged on the chassis 2, the outside of knife box 4 and the connecting plate is fixed, front-wheel leads to The installation axle 10b for crossing front-wheel is connected by adjustable rotary pivoted arm 10 with the leading portion of the opposite side of the connecting plate.

Above example is interpreted as being merely to illustrate the utility model and being different from limiting protection model of the present utility model Enclose.After the content of record of the present utility model has been read, technical staff can be by making various changes to the utility model Or modification, these equivalence changes and modification equally fall into the utility model claim limited range.
