Abstract

The utility model provides a multifunction tree pruner which is a tool of plant shaping and pruning and is driven by a pure soft shaft and a pure soft pipe. An operating rod has a limited bending radius or a limited bending angle degree and can realize the operation of straightness, verticality and an optional angle degree. The multifunction tree pruner is suitable for the pruning of the branch forks of perennial tall trees and the pruning of the branch forks of the trees under an electric wire. The multifunction tree pruner is suitable for the pruning of the branch forks and the root stumps of obstacle trees and the pruning of hedges, turf and tree shapes of offices, enterprises, yards, etc.

Description

Multifunction tree pruner

The invention belongs to a plant species shaping, prune facility.

Before the present invention, the branch fork of domestic each perennial tall and big trees in city is pruned, and complete in heavy hand labour, not only labour intensity is big, speed is slow, and very dangerous.For low position path branch, generally be to adopt averruncator to repair, but this cutting use very inconveniently, cuts off the branch footpath only about 3Cm, labour intensity is big, efficient is low.

Abroad, (the Europe number of patent application is 84810093.9 to the hand-held power beta pruning instrument of Yamada, Sahuji invention, the applying date is on February 27th, 1984), be characterized in by light-duty motor by the transmission of rigidity pipe fitting flexible axle front end bevel gear, cutting tool is a circular saw, body is connected with the rigidity pipe is rigid, and engine, action bars, blade are integral.Though this beta pruning machine has improved beta pruning speed, portion of the handle is overweight during operation, and function singleness produces when circular saw is eaten saw and beats, and is difficult for realizing safety work.JerZy JancZ-aK has invented a kind of beta pruning instrument, and (BP: application number is 8113691) this machine is with the gasoline engine source that is used as power, and drives hydraulic pump, and hydraulic oil drives hydraulic motor by the road, and hydraulic motor drives saw chain work.This beta pruning machine complex structure, cost height, human body bears a heavy burden bigger.

The purpose of this invention is to provide a kind of by the engine source that is used as power, multiple degrees of freedom, multi-functional motor-driven branches of tall trees trimmer.This trimmer is simple in structure, easily manufactured, machine vibration does not act directly on the human body, the human body loading weight is little, when operation, can operate by two people, one people hands action bars, one people pushes driving, any branch that it can make the operator stand in the sawed-off 3.3 meters height in ground is pitched, and eats saw steadily, and trees can not produce the tear fracture phenomenon.

Multi-functional branches of tall trees trimmer job area of the present invention is extensive, not only can prune tall and big trees branch fork; Also can realize hedgerow, tree-like, turf pruning after changing cutter, the root of the trees of tree-walk within 30Cm cuts down; When with the crane supporting operation, go back the tall and big trees in the sectional felling city.The present invention has also noted safety work angle and sight angle, can realize safety work.

Fig. 1 is the structural representation of multi-functional branches of tall trees trimmer.Wherein 1 for operation car, 2 be engine, 3 for fuel tank, 4 for throttle and electric switch, 5 for the engine wobble hanger, 6 for engine positioning control pin, 7 for flexible pipe, 8 for hose coupling, 9 for the internal thread overcoat, 10 for metallic pipe coupling, 11 for the flexible pipe lower contact, 12 for the action bars lower handle, 13 for the action bars upper handle, 14 for metal tube, 15 for flexible axle centering pilot cover location larynx hoop, 17 for housing, 18 for splined shaft, 19 be that saw chain, 24 is the housing locking nut.

Fig. 2 is metal tube, flexible pipe cutaway view.Wherein 16 is that flexible axle top connection, 21 is that flexible axle, 22 is that straight centering pilot cover, 23 is curved surface centering pilot cover; Fig. 3 is the work rod member and the diagram of gears.Wherein 20 is that flexible axle lower contact, 31 is the centrifugal clutch output shaft; Fig. 4 is the chain saw front view.Wherein 26 are the saw plate; Fig. 5 is a chain saw working portion structural representation.Wherein 25 is sprocket wheel; Fig. 6 is a trimming tool structure side view.Wherein 29 is that ledger-plate, 30 is knife section; Fig. 7 is a trimming tool structure vertical view.Wherein 27 is that eccentric wheel, 28 is bearing.

The operation part of multi-functional branches of tall trees trimmer of the present invention, by metal tube (14), action bars upper handle (13), action bars lower handle (12), centering pilot cover larynx hoop (15), metallic pipe coupling (10), internal thread overcoat (9), flexible axle (21), straight centering pilot cover (22), curved surface centering pilot cover (23) constitutes, its main points are that flexible axle (21) is in metal tube (14), felt relieved with curved surface centering pilot cover (23) and straight centering pilot cover (22), therefore when flexible axle rotates, radially depart from controlledly, the hard grind of having eliminated between flexible axle and metal tube is wiped and vibration.The top of flexible axle is connected with centrifugal clutch output shaft (31), and terminal is connected with splined shaft (18), and splined shaft is assemblied in the housing (17), drives saw chain (19) by sprocket wheel (25), or driving eccentric wheel, to drag knife section reciprocating; Metal tube (14) is connected with housing (17), and the front end of metal tube has certain bending radius or angle of bend, and metallic pipe coupling (10) can rotate along hose coupling (8) boss with after the internal thread overcoat is connected.Like this, when stretching on the action bars, can realize sawing straight operation of plate and arbitrarily angled, direction operation.When stretching under the action bars, can realize sawing straight operation of plate and scissors in level, vertical direction operation.

The casing of multi-functional branches of tall trees trimmer of the present invention (17) can connect saw plate (26), also can connect knife section (30), ledger-plate (29).Knife section (30), ledger-plate (29) are the two sides tooth, and the profile of tooth angle is 25 °～35 °.

The mitigation flexible axle tightening device of multi-functional branches of tall trees trimmer of the present invention is made of hose coupling (8) and metallic pipe coupling (10) and internal thread overcoat (9).When this machine was worked, flexible axle (21) produced axial shrinkage, relaxed the axial length variation that the flexible axle constriction device can be regulated flexible axle automatically, reduced the axial tension of flexible axle.The engine of this machine (2) by hanger (5) and the engine positioning control pin (6) of controlling its swing, is installed on the operation car (1).

Multi-functional branches of tall trees trimmer is applicable to the obstacle branch of the tall and big trees of afforestation, withered branch, the pruning of giving birth to branch more, and trees do surely; Electric industry department guarantees that communication quality, safe power supply carried out, and trees branch fork is pruned under the electric wire; The root that may examine the obstacle tree of measurement department in road, sight line are opened cuts down and the pruning of branch fork; Exchange also is applicable to the hedgerow, turf, tree-like pruning in office, enterprise and institute front yard etc. behind the trimming tool.
