Abstract
The invention relates to an improved structure of a high-branch hedge trimmer. The improved structure comprises a power mechanism, a transmission mechanism, a handle, a switch and a blade structure, a desultory oval opening is arranged in the middle of the blade structure, two guide rails are arranged on outer sides of two blades respectively and fixed by bolts penetrating through sliders, and beveling portions are arranged on two faces of the opening. By arranging the blades with different lengths of the openings provided with the sliders and unequal intervals among the openings, when the blades are in reciprocating cutting motion under driving of an eccentric gear, vibration force generated at joints of the blades and the transmission mechanism cannot be transmitted to end portions of the blades, so that overlarge moving of the end portions of the blades cannot be caused due to vibration force of the vertical blade, and increase of friction force between the two blades and possible impact among sawteeth of the two blades can be avoided.
Description
Technical field
The invention belongs to garden instrument field, mainly refer to and a kind ofly for the GREEB HEDGE MACHINE that eminence branch etc. is repaired, improve structure.
Background technology
GREEB HEDGE MACHINE is mainly applicable to the specialty of the afforestation aspects such as tealeaves pruning, park, flower garden, roadside hedge and prunes, and for relatively high hedge etc., directly uses branches of tall trees GREEB HEDGE MACHINE, and staff does not need to carry out operation aloft just can realize pruning.
The basic structure of GREEB HEDGE MACHINE mainly comprises engine, transmission mechanism, handle, switch and blade structure etc.Its basic functional principle is that engine drives blade structure to carry out work through transmission mechanism.
The branches of tall trees GREEB HEDGE MACHINE now using is because its startup is light, simple to operate, the little lightweight feature of volume is widely used.But the existing branches of tall trees GREEB HEDGE MACHINE using, because need to use aloft, in use, need to lift cutter head or lift machine, can cause operator's physical demands.Therefore guaranteeing under the prerequisite of blade structure intensity, alleviating blade weight is the method that reduces user's physical demands, and in the existing blade structure using, two blades are all thinner, and two blades are that slide block by being arranged in guide rail moves.Such structure causes abrasion condition serious, in order to reduce wear, need between slide block and blade, be provided with gap, such interstitial structure can cause the eccentric gear of transmission mechanism in promoting two blade processes, to occur the appearance with the vertical chatter power of blade work direction, such power is the main cause that causes blade to fracture, on the other hand, the appearance of chatter power can cause producing and clashing between cutter tooth adjoint in two blades, causes cutter tooth to fracture.
Summary of the invention
The object of the invention is to improve structure technology scheme by branches of tall trees GREEB HEDGE MACHINE, reduce the defect of the blade structure of existing GREEB HEDGE MACHINE, reduce the wearing and tearing of blade structure, reduce the shock causing because of two blade chatters, improve the service life of blade structure.
The present invention is achieved by the following technical solutions:
Branches of tall trees GREEB HEDGE MACHINE improves a structure, includes:
Actuating unit, for providing power resources;
Transmission mechanism, for by the transmission of power of actuating unit to blade structure;
Handle, for operating machine and controlling the direction of machine;
Switch, for controlling the unlatching of engine or cutting out;
Blade structure, for acting on object to be sheared by the merit through engine transmission; Described blade structure includes two serrate blades of both sides band, in the middle part of blade structure, be provided with and do not connect the elliptical openings of being used to, this opening is used for arranging slide block, two guide rails are arranged at respectively the outside of two blades, by the bolt through slide block, fix, two faces of described opening are provided with an oblique cutting part.
The length of described oblique cutting part vertical blades thickness is blade thickness 1/5th to 1/3rd.
Each is unequal for the length of described opening, for reducing gradually to blade end direction length from transmission mechanism.
Spacing between described adjacent two openings is all unequal, for reducing gradually to blade end direction length from transmission mechanism.
Described slide block is fixed structure with one of them guide rail.
The present invention's beneficial effect is compared with the existing technology:
1, blade openings place is provided with oblique cutting part, has reduced with the coefficient of friction between slide block.
2, the different setting of length of the opening of slide block be set by blade, and the unequal setting of spacing between opening, while carrying out reciprocal shearing motion under the drive of blade at eccentric gear, the chatter power producing with transmission mechanism junction at blade can not transmitted to the end of blade, the end of such two blades not be because the chatter power of vertical blades can cause excessive motion, and increases frictional force between two blades and the shock between issuable two blade sawtooth.
