It is rotatably arranged at pole 9 and the telescopic cylinder 101 collected on jib 3, wherein auxiliary at telescopic cylinder 101 and directive wheel 100
Help down, the front portion of pole 9 with landing ground fluctuating around rotating shaft a fluctuate regulation arrange.
Concrete, by fluctuating of pole 9 leading section, so that circular cutting soil disk 41 being uneven with landing ground
Carrying out automatic up-down adjustment, it is ensured that the degree of depth cut is identical, the shovel being further easy to scraper device 5 takes work.
Again by, the setting of directive wheel 100 can effectively overcome the problems such as straight line or the inclination on ridge, it is ensured that Herba Alii fistulosi is in two
The middle part of individual directive wheel 100, thus the quality of Herba Alii fistulosi after improving results.
Scraper device 5 includes being positioned at the profiling grafter 50 collecting jib 3 leading section.
Tremble soil device 7 and include being positioned at that to collect jib 3 internal for being connected with longitudinal conveying device 6 phase by profiling grafter 50
Annular conveyer chain 51, it is arranged on the convergence part that profiling grafter 50 is connected by the rearward end of profiling grafter 50 with annular conveyer chain 51 phase
52 and for regulation by annular conveyer chain 51 degree of tightness strainer 53, wherein convergence part 52 is in comb teeth-shaped, through convergence part
The Herba Alii fistulosi of 52, the part earth of its root can come off at comb.
Concrete, this annular conveyer chain 51 include the drive sprocket 51a being positioned at both sides and driven sprocket 51b, distinguish the most sheathed
The driving-chain 51c on the drive sprocket 51a and driven sprocket 51b of homonymy, be horizontally set with between the conveyer chain 51c of both sides many
The cross bar 51d that root is arranged in parallel, the space between the most adjacent two cross bar 51d is less than the external diameter of Herba Alii fistulosi root.This example
In, by the comb of convergence part 52 and the setting of annular conveyer chain 51, it is possible to preliminary removes the earth of Herba Alii fistulosi root.
Further, the both ends of cross bar 51d are rotatably arranged on the chain link of driving-chain 51c respectively.
Meanwhile, device 7 also includes mounting bracket 70 to the soil of trembling in this example, being positioned at the Herba Alii fistulosi root left and right sides can be with Herba Alii fistulosi
Sidepiece earth touch first tremble soil unit 711 and second tremble soil unit；Being positioned at bottom Herba Alii fistulosi root can be with mud bottom Herba Alii fistulosi
Soil touch the 3rd tremble soil unit 712；And drive first to tremble soil unit 711 respectively, second tremble soil unit and the 3rd to tremble soil single
The drive mechanism 72 that unit 712 rotates, wherein mounting bracket 70 includes side stand 701, lower supporter 702, and first trembles soil unit 711 He
Two tremble soil unit can be movably arranged on side stand 701 respectively along left and right directions, and the 3rd trembles soil unit 712 can be along
Vertical direction away from or be movably arranged on lower supporter 702 near Herba Alii fistulosi root.
Concrete, first trembles soil unit 711 and second trembles soil unit and is symmetrical arranged and (therefore, second trembles native unit and save mark
Number).
Concrete, first tremble soil unit 711, second tremble soil unit and the 3rd and tremble the setting of soil unit 712 and constitute and tremble
Soil wheel assembly 71.
Further, first tremble soil unit 711 include horizontally disposed power transmission shaft 711a, be arranged on power transmission shaft 711a
Wheel disc 711b, multiple trembling soil blade 711c around the circumference of wheel disc 711b is equally distributed, wherein wheel disc 711b can be along biography
The bearing of trend of moving axis 711a moves and is adjustably arranged on power transmission shaft 711a, trembles soil blade 711c and includes in wheel disc 711b
The heart is outward extending tremble soil handle of a knife 711d, certainly tremble that the outer end of soil handle of a knife 711d bends inwards tremble soil cutter head 711e.
In this example, trembling soil blade 711c has 4, and circumferentially distributed, by according to wheel disc 711b energy around wheel disc 711b
The setting of enough mobile regulations, it is possible to moving left and right of soil blade 711c is trembled in regulation, can meet different work requirements.
Meanwhile, in Herba Alii fistulosi course of conveying, power transmission shaft 711a drive wheel disc 711b and tremble soil blade 711c rotation so that
Tremble soil cutter head 711c to touch with the earth of Herba Alii fistulosi root both sides so that earth comes off.
Concrete, the 3rd trembles soil unit 712 includes the cylinder 712a that can rotate around horizontal axis direction, around cylinder
The equally distributed multiple blade 712b of circumference of 712a.
Cylinder 712a is arranged on the leading section of lower supporter 702, and what the rearward end of lower supporter 702 can rotate is arranged on frame
On 1.Such that it is able to regulate the distance bottom cylinder 712a and Herba Alii fistulosi, it is simple to blade 712b and touching bottom Herba Alii fistulosi so that mud
Soil comes off.
In this example, by both sides tremble soil blade 711c and the blade 712b of bottom, it is achieved the removal of earth bottom Herba Alii fistulosi,
Reducing the earth of Herba Alii fistulosi root after gathering further, the work bundled for follow-up piling brings convenience.
Meanwhile, drive mechanism 72 include being respectively used to driving both sides power transmission shaft 711a rotate the first gear unit 720, for
Drive the second delivery unit 721 that cylinder 712a rotates.
Concrete, the first gear unit 720 include drivewheel, be set in the driven pulley of end part of driving shaft, transmission band, for
Drive motor and for regulating the tensioner of conveyer belt.
Second delivery unit 721 is identical with the first gear unit 720 structure, is not detailed at this.
Above-described embodiment, only for technology design and the feature of the explanation present invention, its object is to allow person skilled in the art
Scholar will appreciate that present disclosure and implements according to this, can not limit the scope of the invention with this, all according to the present invention
The equivalence that spirit is made changes or modifies, and all should contain within protection scope of the present invention.
