Technical field
The present invention relates to greening lawn pruning tool field, specifically, it is that one kind is used for pruning greening lawn hand push row
Formula trimmer.
Background technology
Afforestation is not only used for increasing a kind of mode of green coverage, purify air now, even more embodies gardens
The engineering of design, garden, cell, or even city image, now current greening is widely used in urban construction, roadside greening and high speed
The isolation strip greening of highway.Species with present greening and the continuous expansion of area, work gardens repaired and safeguards
Amount is also increasing, and in order to reach high efficiency, high-quality garden maintenance purpose, present pruning maintenance service is from the initial stage
Hand-operated tools prune be transitioned into electric tool, the semi-automatic pruning of internal combustion engine instrument.
Greening maintenance is pruned the most frequent, and the pruning on what area was maximum surely belong to lawn is safeguarded, such as, urban road lawn every
From band, golf course etc..Existing turf-mown instrument is mainly carried out using vane type blade, and that is, existing pruning car is
By arranging the vane type blade of a high-speed rotation in go-cart bottom, lawn is cut by the high-speed rotation using vane type blade
Fall, because the blade of high-speed rotation is arranged on the bottom of go-cart, therefore, safety is higher, but there is also following defect, its
One, because the rotary speed of blade is very big, usually more than thousand turns, if encountering hard thing during pruning, such as stone etc. can be straight
Connect and cause the damage of blade even to fracture；Second, the lawn width of this kind of go-cart pruning is relatively small, general impeller blade is
Large radius at 60-70 centimetre, the limited efficacy of pruning；Third, the blade of high-speed rotation during cutting the grass on a lawn, noise is relatively
Greatly.
Content of the invention
It is an object of the invention to provide one kind is used for pruning greening lawn hand push row's formula trimmer, existing for solving
The following problem that hand propelled impeller blade lawn mower exists：First, because the rotary speed of blade is very big, usually more than
Thousand turns, if encountering hard thing during pruning, such as stone etc. can directly contribute the damage of blade or even fracture；Second, this kind pushes away
Car prune lawn width relatively small, general impeller blade maximum radius at 60-70 centimetre, the limited efficacy of pruning；Its
Three, the blade of high-speed rotation noise during cutting the grass on a lawn is larger.Impeller is pruned and is changed to dislocation type pruning dress by the present invention
Put, have that shearing width is big, efficiency high, noiselessness, safe and practical advantage.
In order to realize above-mentioned technique effect, the present invention is achieved through the following technical solutions：

Preferably, described quiet cutter head is identical with the shape of dynamic cutter head and is isosceles triangle.
Preferably, eccentric shaft has wear resistant alloy material to make.
The present invention compared with prior art, has advantages below and beneficial effect：
（1）The present invention passes through to substitute the shearing of existing impeller blade using sawtooth dislocation type shear, solves impeller knife
The noise problem that the high-speed rotation that chip grass mower exists produces；Run into damage or the breakage problem that hard thing can cause blade；
And the width limitation problem that single shearing cuts the grass on a lawn；Blade of the present invention（Top cutter and bottom knife）Can actual need
Length to be arranged, to improve the lawn width of single shearing, improves the pruning efficiency.
（2）The present invention drives the linear reciprocating motion of top cutter by eccentric shaft structure, thus realizing and bottom knife
Cooperation shearing, it is huge to have noiselessness, power, the high feature of shearing frequency, and further, eccentric shaft is made using antifriction alloy,
Long service life.
（3）Compressed by retaining mechanism between top cutter in the present invention and bottom knife, eliminate because top cutter with
The gap existing between bottom knife is cut during leading to turf-mown and continuous problem exists, and has thoroughly eradicated turf-mown not
Equal problem.
