Detailed description of the invention
Novel for the ease of understanding this, it is described more fully the most novel below with reference to relevant drawings.Accompanying drawing gives this novel preferred embodiment.But, basis is the most novel can be realized in many different forms, however it is not limited to embodiment described herein.On the contrary, providing the purpose of these embodiments is to make the understanding to this novel disclosure more thorough comprehensively.
Unless otherwise defined, the implication that the those skilled in the art that all technology used herein are novel with belonging to this with scientific terminology are generally understood that is identical.It is intended merely to describe the purpose of specific embodiment at this novel term used in the description herein, it is not intended that this is novel in limiting.
As it is shown in figure 1, a kind of milling combined type nursery seedling circumference of boring of this novel offer cuts out root cutter head, including drill bit 1, blade and rotation mandrel 4, wherein blade is made up of milling cutter section.Drill bit 1 be connected with the milling cutter section of blade after integral installation in rotation mandrel 4, drill bit 1 can rotate around rotation mandrel 4.Whole cutter head uses fabricated structure, it is simple to mounting or dismounting.
As shown in Figure 2, the outline 5 of drill bit 1 is arc taper, and it is consistent with the incidence curve of Squama Manis, i.e. designs by measuring its incidence curve size, it can be made to pierce underground more rapidly.Axially it is machined with the first chip area 6 on drill bit 1 along it, in order to carry out chip removal, and squeezes the first-class foreign material of gravelstone.The tip of drill bit 1 is machined with chisel edge 7, so contributes to drilling hard stratum or sand stone layer.The end of drill bit 1 is threaded hole 8, radially fixed for carrying out threadeding with rotation mandrel 4 realizing.Using pairing on castellated connection, i.e. both joint faces to be machined with 10 ~ 20 strip dovetail grooves 9 between drill bit 1 and the lower milling cutter section 2 of blade, the described mutual tabling of dovetail groove 9 realizes castellated connection, thus realizes the axial restraint of lower milling cutter section 2 and drill bit 1.In the present embodiment, in order to ensure the reliability coupled, the quantity of dovetail groove 9 is 20.Described first chip area 6 is cone in the shape of a spiral, and its helical angle rises to 20.4 ° from 12.8 °, uses the conical tip sharpness that can ensure whole drill bit 1, can effectively reduce drilling drag.
As shown in accompanying drawing 3 and accompanying drawing 4, in order to ensure the rigidity of whole cutter head, lower milling cutter section 2 uses three sections of compositions, between adjacent lower milling cutter section 2, is also respectively adopted castellated connection forms between lower milling cutter section 2 and upper milling cutter section 3.Whole blade i.e. descends and is machined with 16 ~ 32 cutter grooves 12 along two imitative DNA helixes 11 respectively in milling cutter section 2 and upper milling cutter section 3.In the present embodiment, cutter groove 12 has 64, and its width is 11 ~ 25mm, preferably 25mm, and the helical angle that imitative DNA helix 11 is formed is 30 ° ~ 40 °, preferably 36 °.Kapok thorn shape cutter 10 is installed in described cutter groove 12.
As shown in Figure 5, kapok thorn shape cutter 10 uses combinative structure, taper its tapering of handle of a knife 14(used is 7:24) it is fixed on the cutter groove 12 of blade by screw and conical surface transition cooperation, the upper end shape of kapok thorn shape cutter 10 is consistent with the spine shape (being i.e. covered with spine on the trunk of silk cotton tree) in silk cotton tree, the drift angle of kapok thorn shape cutter 10 is 40 ° ~ 50 °, it is preferably 44 °, head is that fillet is to reduce tipping, kapok thorn shape cutter 10 upper end is symmetrily processed with two corrugated second chip areas 13, and employing waveform can be with more convenient chip breaking and chip removal.
As shown in Figure 6, rotation mandrel 4 uses hollow axle 16 to be welded on mandrel flange 17, hollow in the middle part of it, to alleviate the gross weight of overall cutter head.In order to reduce difficulty of processing, hollow axle 16 uses pipe, mandrel flange 17 to be connected with the upper surface of upper milling cutter section 3 by screw.Being threaded step 15 on the end periphery of hollow axle 16, can facilitate and threaded with drill bit 1, hollow axle 16 can stretch into 20mm in drill bit 1, it is ensured that drill bit 1 radially fixed.
In the present embodiment, the total length cutting out root cutter head is about 1m, the wherein a length of 800mm of blade, the a length of 240mm of drill bit 1, the thickness of mandrel flange 17 is 10mm, a diameter of φ 80mm of blade, kapok stings a diameter of φ 117mm on shape cutter 10 at point of a knife, and the entire length of rotation mandrel 4 is 830mm.
Work process: before cutter head carries out seedling circumference sanction root, power drive cutter head high speed rotating, drill bit 1 drives whole cutter head to pierce under soil layer and bores under stopping behind about 1m depths, complete the feeding process that cutter head is downward.Owing to drill bit 1 forms according to the incidence Curve Design of Squama Manis so that it is bore soil and casting is the most smooth.During cutting out root, Manual-pushing is mounted with the wheeled cart of this sanction root cutter head, walks circle or square trace around seedling periphery, and the kapok thorn shape cutter 10 on blade will participate in circumference by sword and cut out root, complete circular or square cutting.Owing to kapok thorn shape cutter 10 is in DNA spiral distribution, on the basis of realizing circumference sanction root functionality, there is reduction and bore milling noise, power consumption and the beneficial effect of tool wear.Kapok thorn shape cutter 10 is consistent with the spine shape in silk cotton tree, and has two corrugated second chip areas 13, it is ensured that kapok thorn shape cutter 10 sharp firm while, it is to avoid tipping or soil are considered to be worth doing and are blocked blade problem.It addition, blade end face axial is connected by castellated connection, and with rotation mandrel 4, blade is carried out radially fixed, the bonding strength of kapok thorn shape cutter 10 can be improved, it is ensured that the stable operation of kapok thorn shape cutter 10.Thus achieve and carry out cutting out the process of root with a kind of milling combined type nursery seedling circumference sanction root cutter head that bores.
Above-described embodiment is this utility model preferably embodiment; but this novel embodiment is also not restricted to the described embodiments; other any without departing from the change made under this most novel spirit and principle, modify, substitute, combine, simplify; all should be the substitute mode of equivalence, within being included in this novel protection domain.
