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 the garden instrument field, refer to that mainly a kind of GREEB HEDGE MACHINE for eminence branch etc. is repaired improves structure.
Background technology
GREEB HEDGE MACHINE mainly is applicable to the specialty of the afforestation such as tealeaves pruning, park, flower garden, roadside hedge aspect and prunes, and for relatively high hedge etc., directly uses the branches of tall trees GREEB HEDGE MACHINE, and the 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 carries out work through transmission mechanism drive blade structure.
The branches of tall trees GREEB HEDGE MACHINE that now uses is light, simple to operate because of its startup, the little lightweight characteristics of volume are widely used.But the existing branches of tall trees GREEB HEDGE MACHINE that uses in use, need to lift cutter head or lift machine because need to use aloft, can cause operator's physical demands.Therefore under the prerequisite that guarantees blade structure intensity, alleviating blade weight is the method that reduces user's physical demands, and in the existing blade structure that uses, two blades are all thinner, and two blades are to move by the slide block that is arranged in guide rail.Such structure causes abrasion condition serious, need to be provided with the gap between slide block and blade in order to reduce wear, appearance with the chatter power of blade work perpendicular direction appears in the eccentric gear that such interstitial structure can cause transmission mechanism in promoting two blade processes, such power is the main cause that causes blade to fracture, on the other hand, the appearance of chatter power can cause producing between cutter tooth adjoint in two blades clashes into, and causes cutter tooth to fracture.
Summary of the invention
The objective of the invention is to improve the structure technology scheme by the branches of tall trees GREEB HEDGE MACHINE, reduce the defective of the blade structure of existing GREEB HEDGE MACHINE, reduce the wearing and tearing of blade structure, reduce the shock that causes because of two blade chatters, improve the service life of blade structure.
The present invention is achieved by the following technical solutions:
A kind of branches of tall trees GREEB HEDGE MACHINE improves structure, includes:
Actuating unit is used for providing power resources;
Transmission mechanism is used for transmission of power with actuating unit to blade structure;
Handle is used for operating machine and controls the direction of machine;
Switch is used for controlling the unlatching of engine or cutting out;
Blade structure is used for acting on through the merit of engine transmission object to be sheared; Described blade structure includes two serrate blades of both sides band, be provided with in the middle part of blade structure 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, fix by the bolt that passes slide block, two faces of described opening are provided with an oblique cutting part.
The length of described oblique cutting part vertical blades thickness is 1/5th to 1/3rd of blade thickness.
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 beneficial effect that the present invention compares with prior art is:
1, the 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, reach the unequal setting of spacing between opening, when carrying out reciprocal shearing motion under the drive of blade at eccentric gear, can not transmit to the end of blade with the chatter power of transmission mechanism junction generation at 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.
