Tool, two cutters of dredging are symmetrically fixed in rotating shaft through cutter mounting frame and connecting rod, and the cutter of dredging is oblique by drilling cutter head
Outwards arrangement, the mud discharging mechanism include the upward blade of two edge rotating shaft spirals upwards.
Above-mentioned prior art is coordinated using drilling cutter head dredges cutter and helical blade is digged pit, and helical blade is used for will
The soil agitation of plane pine separates drilling cutter head, but helical blade can be made cutter by very big resistance during digging pit
Easily because the resistance that is subject to and rubbing or even damages excessive and rust, cutting-tool's used life is reduced.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of knife for Tree Planting Earthdrill
Tool, the resistance and friction that cutter is subject to during being digged pit with reduction, makes cutter be not easy rust and damage, improves the use of cutter
The advantages of life-span.
To achieve the above object, the utility model provides following technical scheme：A kind of cutter for Tree Planting Earthdrill,
The helical blade of the drilling rod is connected to including drilling rod and spiral surrounding, the drilling rod is connected with drill bit, the helical blade bag
The native blade that send close to the native blade of plane of the drill bit and away from the drill bit is included, the native blade of plane send native blade to exist with described
The diameter of junction is equal and the diameter of the native blade of the plane is gradually reduced towards close to the drill bit direction.
Using above-mentioned technical proposal, because the native blade of plane is equal with sending diameter of the native blade in junction and digs native blade
Diameter is gradually reduced towards close to drill bit direction, is reduced resistance and the friction dug suffered by native blade, helical blade is not easy rust
And damage, cutting-tool's used life is improved,.
The utility model is further set, and the one side of the native blade of plane towards the drill bit, which is provided with, digs native knife.
Using above-mentioned technical proposal, dig the plane soil knife on native blade and be used to dig loose soil, make the mud for being sent native blade transmission
Soil is looser, is advantageous to the transmission for sending native blade to soil；And the native knife of plane can also reduce the resistance dug suffered by native blade
And friction, the process for making to dig pit become more smooth, deepen depth of digging pit, improve the operating efficiency of Tree Planting Earthdrill.
The utility model is further set, and the one side of plane native blade towards the drill bit is provided with geometrical clamp, the plane
Native knife is removably mounted on the geometrical clamp.
Using above-mentioned technical proposal, be advantageous to dig the dismounting and replacing of native knife, and the native knife of plane can be pulled down when not in use,
Avoid digging native knife accident scratch in the handling process to people or thing.
The utility model is further set, and the native knife of the plane by bolt connection at two with being fixed on the geometrical clamp.
Using above-mentioned technical proposal, dig bolt connection increase at two on native knife and dig stable connection of the native knife on geometrical clamp
Property, and dig native knife and be not easy to loosen on geometrical clamp when digging native.
The utility model is further set, and the thickness of the helical blade inwardly gradually increases from outward flange.
Using above-mentioned technical proposal, the structural strength of helical blade is added, helical blade is not in quick rotation for cutter
Easily deform upon and damage, further increase cutting-tool's used life.
The utility model is further set, and the helical blade is connected with the junction of the drilling rod for fillet.
Using above-mentioned technical proposal, due to cutter, the junction of drilling rod and helical blade produces ten in quick rotary course
Divide big stress, fillet connects the concentrated stress that can effectively alleviate drilling rod and helical blade junction, makes drilling rod and helical-blade
Piece is hardly damaged, and further increases cutting-tool's used life.
The utility model is further set, and the drill bit thread is connected to the drilling rod.
Using above-mentioned technical proposal, facilitate the dismounting of drilling rod and drill bit, and bit wear speed ratio under normal conditions
Drilling rod is fast, and only drill bit need to be changed when bit wear rust, and the miscellaneous part of drilling rod and cutter can be continuing with,
Improve the utilization rate of cutter.
In summary, the utility model send native blade and diameter gradually to reduce towards drill bit direction by the way that helical blade is divided into
Plane soil blade, and dig native knife in the one side installation for digging native blade towards drill bit, the process for making to dig pit becomes more smoothly, to deepen
Dig pit depth, and the resistance suffered by helical blade and friction can also be reduced, helical blade is not easy rust and damage, improve
Cutting-tool's used life.
