Description
Technical field
The present invention relates to garden instrument fields, are to be related to one kind from garden shearer particularly.
Background technology
In afforestation maintenance process, it is often necessary to use garden shearer pollard;And floristics is various in gardens,
Often difference is larger for the limb of various types of plant, then when being trimmed using fixed garden shearer, encounters more bruly wood
Branch, trimming process are often more painstaking.
Invention content
In view of the above-mentioned problems, the purpose of the present invention is to provide a kind of adaptive garden shearer, which can trim
In the case that resistance is larger, the arm of force is stretched automatically, to reduce trimming difficulty, keeps trimming process more laborsaving.
The technical solution adopted by the present invention to solve the technical problems is:The adaptive garden shearer is hinged including two
Scissors half portion;Each scissors half portion includes cutter head, handle of a knife;The handle of a knife includes and the fixed negative winding stem of cutter head, the negative winding stem
Inside extend downwardly one section of downward section parallel with handle of a knife axis, downward section of the lower inside sets that there are one elastic hydraulics
Chamber;The handle of a knife further includes handle body, the upper end of the handle body upwardly extend one section it is parallel with handle of a knife axis on prolong section, it is described on
The upper end for prolonging section is articulated with the negative winding stem so that the elastic hydraulic chamber be sandwiched in described downward section, on prolong section between, and by
Downward section, on prolong the extruding of section and shrink;Set along axis that there are one the hydraulic pressure being connected to the elastic hydraulic chamber in the handle body
Slideway;The sliding plug being fixed to each other, slide bar are equipped in the hydraulic pressure slide track;The slide bar extends downwardly out the hydraulic pressure slide track, and
It is connected to grip part.
Preferably, the elastic hydraulic chamber is an elastic glueballs for being full of hydraulic oil, and outside the elastic glueballs
Also be nested with a both ends be supported in described downward section, on prolong the compression spring of section.
Preferably, the elastic hydraulic chamber is a telescopic hydraulic cylinder, and the axis of the telescopic hydraulic cylinder is perpendicular to institute
State downward section;It is equipped with returning spring in the telescopic hydraulic cylinder, so that after it is compressed, can again be stretched under returning spring effect
Exhibition.
Preferably, the radial fit gap between the slide bar and the hydraulic pressure slide track is not more than 0.2mm;To prevent on-slip
Bar radially shakes.
Preferably, the grip part is in long barrel shape, the slide bar is connected to the bucket bottom of the grip part, and in the cunning
Bar slides up and down in range, and the inner wall of the grip part is placed on the surface of the handle body always, to make grip part and handle
There is rock-steady structure between body, prevent from radially loosening between grip part and handle body.
The beneficial effects of the present invention are:In poll, handle of a knife gradually closes up the adaptive garden shearer, during this,
Prolong section and negative winding stem on the handle body downward section gradually squeezes the elastic hydraulic chamber, and shearing resistance is bigger, then elastic liquid
Press the compression degree of chamber bigger, then elastic hydraulic chamber is filled with more hydraulic oil to the hydraulic pressure slide track, and the slide bar is protruding
It is more;I.e. as the increase of shearing resistance, the length of entire handle of a knife gradually increase, so that the arm of force is increased, to reduce trimming difficulty, make
User keeps more labour-saving to trim operation process.
Description of the drawings
Fig. 1 is one embodiment schematic diagram of this adaptive garden shearer.
Fig. 2 is the structural schematic diagram of handle of a knife in Fig. 1 embodiments.
Specific implementation mode
In Fig. 1, embodiment shown in Fig. 2, the adaptive garden shearer include two scissors half portion 1a being hinged,
1b;Each scissors half portion includes cutter head, handle of a knife;The handle of a knife include with the fixed negative winding stem 11 of cutter head, the negative winding stem 11 it is interior
Side extends downwardly one section of downward section 111 parallel with handle of a knife axis, and downward section 111 of the lower inside sets that there are one elastic liquid
Press chamber 12;The handle of a knife further includes handle body 13, the upper end of the handle body 13 upwardly extend one section it is parallel with handle of a knife axis on prolong
Section 131, it is described on prolong the upper end of section 131 negative winding stem 11 be articulated with by shaft 110 so that 12 quilt of elastic hydraulic chamber
Be clipped in described downward section 111, on prolong section 131 between, and by downward section 111, on prolong the extruding of section 131 and shrink;The handle body
Set along axis that there are one the hydraulic pressure slide tracks 130 being connected to the elastic hydraulic chamber 12 in 13;Phase is equipped in the hydraulic pressure slide track 130
Mutual fixed sliding plug 14, slide bar 15;The slide bar 14 extends downwardly out the hydraulic pressure slide track 130, and is connected to grip part 16.
Above-mentioned adaptive garden shearer, the elastic hydraulic chamber 12 can be an elastic glueballs for being full of hydraulic oil, and
Also be nested with outside the elasticity glueballs both ends be supported in described downward section 111, on prolong the compression spring of section 131.This kind design
12 structure of elastic hydraulic chamber is relatively simple, and cost is relatively low.Alternatively, the elastic hydraulic chamber 12 can also be by a telescopic hydraulic
Cylinder, and the axis of the telescopic hydraulic cylinder is perpendicular to described downward section 111;Returning spring is equipped in the telescopic hydraulic cylinder, so that its
After compressing, it can be re-expanded under returning spring effect.It is more steady using the elastic hydraulic cavity configuration of telescopic hydraulic cylinder form
Gu it is reliable, it is durable.
In addition, the radial fit gap between the slide bar 15 and the hydraulic pressure slide track 130 is not more than 0.2mm;To prevent
Slide bar 15 is radial to be shaken.In the present embodiment, the grip part 16 is in long barrel shape, and the slide bar 15 is connected to the grip part 16
Bucket bottom, and sliding up and down in range in the slide bar 15, the inner wall of the grip part 16 are placed on the handle body 13 always
Surface prevents from radially loosening between grip part 16 and handle body 13 to make have rock-steady structure between grip part 16 and handle body 13.
In poll, handle of a knife gradually closes up above-mentioned adaptive garden shearer, during this, prolongs section on the handle body 13
131 gradually squeeze the elastic hydraulic chamber 12 with downward section 111 of negative winding stem 11, and shearing resistance is bigger, then elastic hydraulic chamber 12
Compression degree it is bigger, then elastic hydraulic chamber 12 is filled with more hydraulic oil to the hydraulic pressure slide track 130, and the slide bar 14 is to overhanging
Go out more;I.e. as the increase of shearing resistance, the length of entire handle of a knife gradually increase, the arm of force is made to increase, to reduce trimming difficulty,
User is set to keep more labour-saving trimming operation process.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention.
