Description
Technical field
Garden maintenance field of tool, more particularly to relevant gardens pruning tool equipment field are the utility model is related to, specifically
Say, be a kind of pneumatic type long-handled pruner.
Background technology
Hand-bill is a kind of equipment of the most commonly used a kind of pruning trees in landscape design, plant, is to be used to make
One of indispensable instrument of excellent plant art, but existing hand-bill is also in more traditional old state, according to operation side
The difference of formula, manual and motor-driven two kinds can be divided into.The manual hand-bill of the first kind is simple in construction, similar to scissors, only
It is size many bigger than common scissors, handle is longer, more laborsaving.The power of motor-driven hand-bill is generally carried by internal combustion engine
For typically from small-sized gasoline engine, its weight is small, and rotating speed is fast, for the existing enough power of trees beta pruning, is also convenient for taking
Band；But the existing hand-bill of above two operation when must hand-held, therefore can not the ornamental trees and shrubs higher to position enter
Row trimming.
Prior art 1：Application number 201610164351.5, the A of publication No. CN 105706754 disclose a kind of trees beta pruning
Device, solves branch pruning saw of the prior art without safe insulation measure, the deficiency that potential safety hazard during use be present.The present invention
A kind of trees hand-bill provided, insulating bar is fixed with electric saw, the control that control electric saw is fixed with the lower end of insulating bar is opened
Close, when operating personnel carries out branch pruning using electric saw, operating personnel operates electric saw by insulating bar, even if so that electric saw
Operating personnel will not also be injured by being contacted with live wire, improve the security performance of hand-bill when in use；It is also solid on electric saw
Surely there are the detection means of detection saw blade running status, and the detection means and controller communication, controller, which can control, to be located at
The alarm of insulating bar lower end, after controlling switch is opened during operating personnel's pollard, when electric saw failure saw blade is not transported
When dynamic, detection means makes alarm equipment alarm to prompt operating personnel by controller, optimizes the performance of hand-bill.
Prior art 2：Application number 201410792934.3, the A of publication No. CN 104472242 disclose a kind of telescopic electricity
Dynamic hand-bill, the machine are arranged on the top of hand-bill by the power-driven saw of DC motor Driver, are reliably connected with expansion link；
Branch imports the top side that bar is arranged on expansion link, and branch feeding mouth is formed with power-driven saw；Blade shroud is arranged on electronic
The outside of saw blade；One end of spiral conducting line penetrates expansion link below expansion link, and connects with the direct current generator in power-driven saw
Connect, the plug of the other end is flexibly connected with the socket of batteries；Batteries are behind vest type knapsack.Battery
When group needs charging, the plug access power supply on spiral conducting line is pulled up.Power switch is arranged on expansion link, expansion link
When length needs regulation, spiral set lever can be unclamped, outer bar carries out length adjustment in pulling, set and locking screw again after regulation
Set lever.
Utility model content
The purpose of this utility model is to provide a kind of pneumatic type long-handled pruner, for solving what is mentioned in background technology
The problem of higher branch in position is trimmed in existing hand-bill inconvenience.
The utility model is achieved through the following technical solutions：
A kind of pneumatic type long-handled pruner, include for trimming in high-order tree limb, including for cutting limb
Chopping disk, the wind turbine of chopping disk rotation at a high speed is driven by rotating shaft, is fixedly connected with the shell body of the wind turbine

The high-pressure air pipe that high pressure draught is passed through in wind turbine is respectively provided with position；The shell body of the wind turbine is relative to high-pressure air pipe
Side be provided with for pressure release and exhaust steam vent.
Operation principle：The high pressure draught into stock is formed after pressure-air enters wind turbine by high-pressure air pipe, in high pressure
Impeller high-speed rotation is promoted in the presence of air-flow, impeller drives rotating shaft, then drives chopping disk to be rotated coaxially with rotating shaft, chopping disk profit
Directly acted on the high-speed driving and inertia of impeller and be trimmed to about branch, branch is accurately cut, reaches the purpose of trimming.
The utility model is also specially provided with both stage impellers, and impeller to increase the moment of torsion of chopping disk under identical speed conditions
On blade setting in curved surface, because the direction that the blade of impeller is bent enters with high pressure draught in opposite direction, work as high pressure gas
Stream enter wind turbine after, air-flow enter two neighboring blade between, under the guide functions of the bending of blade in itself, air-flow from
The point of impeller flows to root, because root does not have any pod apertures that pressure release can be carried out to air-flow, therefore in height
Under the constant impingement of pressure gas stream, impeller just generates a powerful eccentric moment, so as to drive shaft high-speed rotation, reaches and cuts
The purpose cut.
In order to preferably realize the utility model, further, the chopping disk outer rim is connected with multiple in unified
The cutting teeth of direction bending, the cutting teeth are less than from root to gradual thinning and cutting teeth the cutting face thickness of thickness at tip
1 millimeter, the ultimate range at root to the tip of cutting teeth is no more than 8 millimeters.It is to avoid to small straight using the purpose of the setting
The problem of clamping stagnation is easily produced when footpath branch is cut, and being cut to major diameter branch, if cutting teeth it is too small and
The cutting efficiency of appearance is low, and speed is slow, while when depth of cut is larger, easily causes the depth of parallelism of chopping disk because holding shakiness
Blessing power that is not high and making chopping disk 2 and branch is excessive and is not easy to take, the problem of causing clamping stagnation.
In order to preferably realize the utility model, further, the expansion link is using more hollow pipes being mutually inserted
Composition, and adjacent two hollow pipe ends are provided with adaptable anticreep bulge loop and neck, and the spiral is placed with hollow pipe
Tracheae, the maximum tension length of the spiral tube are more than the maximum extension length of the expansion link.Due to the utility model solution
Subject matter certainly is can freely to be carried out not by the length change of expansion link in the case where not utilizing aid
Level branch pruning, therefore, in order to evade taking into account for the length change of expansion link and power output, the utility model
The uninterrupted conveying of gases at high pressure is realized using spiral tube, while and can meets that the state of the different length of expansion link is carried out
Work.
In order to preferably realize the utility model, further, the spiral tube is close to the expansion link away from wind wheel
One end end of machine is connected with the ball valve for being turned on or off gas in spiral tube, the ball valve it is outer
Housing is fixedly connected with expansion link and opening and closing is realized in the driving of the spanner by being connected with ball valve.
The utility model compared with prior art, has advantages below and beneficial effect：
（1）The utility model avoids biography by setting up expansion link and hand-bill being driven with reference to pneumatic mode
Dynamic manual hand-bill and oil-engine driven hand-bill place one's entire reliance upon effective beta pruning height model that the hand-held of people is brought
The limitation enclosed, independently the gardens branch of higher position effectively can be trimmed.
（2）The peace that the utility model can effectively avoid easily occurring by internal combustion engine or electronic mode using pneumatic mode
Full hidden danger and failure is set, this only only has wind wheel using the core component of the pneumatic wind turbine of new use, belongs to purely mechanic knot
Structure, the problem of being substantially not present failure, practicality and reliability it is very high.
