Abstract
The utility model discloses a screw type cutterhead for a planting pit digging machine, and the screw type cutterhead mainly consists of a disk composed of three screw blades, a locating drill bit and a cutting edge, wherein the locating drill bit is fixed at the center of the disk, and the cutting edge and the screw blades are integral; the screw blades are in variable helix lift angle types, the disk is integrally small in the diameter of the upper part and large in the diameter of the lower part, and the locating drill bit is in a taper cone shape. The cutterhead is simple in structure to save the space, high-quality, quick, safe and reliable in pit digging, and can be used for efficiently improving the planting efficiency and reducing the pit digging cost. The screw type cutterhead for the planting pit digging machine can adapt to the conditions of different pit depth requirements, topographical change, soil hardness and the like without being limited by use places, and can be widely applied to the aspects of mountain forest development, urban landscaping, road construction and the like.
Description
Technical field
Basis is practical to relate to agricultural with machinery, the spiral cutterhead of especially a kind of Tree Planting Earthdrill.
Background technology
Improve forest coverage, preserve the ecological environment, check winds and fix drifting sand and to begin from afforestation.Since the reform and opening-up, whole nation voluntary afforestation has surpassed 475.7 hundred million strains, and forest coverage is increased to present 18.21% by 12% of early 1980s; The afforestation coverage rate in urban construction district, city by 1981 10.1% rise to of today 31.66%.Green has been improved our ecotope, has also planted green shade in the heart people.
Utilize afforestation equipment to realize the mechanization tree planting, can quicken afforestation.Wherein, cutterhead is the important mechanism of Tree Planting Earthdrill, and its performance directly influences the speed and the quality of afforestation.At present, the cutterhead of domestic and international Tree Planting Earthdrill adopts spiral basically, though overall structure is simple, has defectives such as volume is big, weight is big.
The utility model content
This practical technical problem that will solve provides a kind of reasonable in design, simple in structure, conserve space, working stability, adaptability is strong, with low cost and keep in repair the spiral cutterhead of Tree Planting Earthdrill easily.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: the spiral cutterhead of Tree Planting Earthdrill; The disk that mainly is made up of three helical blades, location drill bit and cutting edge are formed, and the location drill bit is fixed on disc centre, and cutting edge and helical blade are one; Helical blade is for becoming the lead angle formula, and disk integral body is that the little lower diameter of upper diameter is big, and the location drill bit is that taper is conical.
The location drill bit is made up of the axis on top and the drill bit of bottom, and axis is provided with keyway and dowel hole.
Three helical blades are evenly distributed on the circumference of axis, and the difference of disk upper diameter and lower diameter is 10～20 millimeters.
The helical blade in the vertical direction is four lead angles of distribution evenly, and each lead angle is respectively from top to bottom
145～65 degree,
235～45 degree,
325～35 degree,
415～25 degree.
Cutting edge is zigzag and has the basil that a plurality of cutting edges closely are arranged on the straight line of helical blade bottom.
The spiral cutterhead of the Tree Planting Earthdrill of the utility model mainly comprises disk, location drill bit and the cutting edge that three helical blades constitute, and its plane formula structure has been practiced thrift the space and has been convenient to store up, and total quality gently reduced power consumption, also maintains easily and keeps in repair.When spiral cutterhead is worked; Under moment of torsion and responsive to axial force, cutterhead rotation and the soil of motion cutting vertically downward, the location drill bit is at first located; Cutting edge cuts soil then; Soil under the cutting is thrown to hole along helical blade, thus realize high-quality fast, dig pit safely and reliably, improve tree planting efficient and the reduction cost of digging pit effectively.The utility model does not receive the restriction of place to use, can adapt to conditions such as the dark requirement in different holes, landform variation and soil hardness, can be widely used in aspects such as mountain forest exploitation, urban afforestation, highway construction.

Embodiment
Extremely shown in Figure 4 like Fig. 1, the spiral cutterhead of the Tree Planting Earthdrill of the utility model, the disk that mainly is made up of three helical blades 1, location drill bit and cutting edge 2 are formed, and the location drill bit is fixed on disc centre, and cutting edge 2 is an one with helical blade 1; The location drill bit is that taper is conical, is made up of the axis 3 on top and the drill bit 4 of bottom, and axis 3 is provided with keyway 5 and dowel hole 6; Helical blade 1 is for becoming the lead angle formula, and three helical blades 1 are evenly distributed on the circumference of axis 3 (every fan angle 11 is 110 degree), helical blade 1 in the vertical direction four lead angles 7,8,9,10 that evenly distribute, and each lead angle is respectively from top to bottom
145～65 degree,
235～45 degree,
325～35 degree,
415～25 degree; Disk integral body is that the little lower diameter of upper diameter (D1) (D2) is big, and difference (Δ D) is 10～20 millimeters; Cutting edge 2 is for zigzag and have the basil, and a plurality of cutting edges 2 closely are arranged on the straight line of helical blade 1 bottom.
Wherein, keyway 5 is used for carry-over moment and fixation cutter head with dowel hole 6, and cutting edge 2 is used to cut soil, helical blade 1 soil of cutting is taken out of and the hole of dishing out outside.Lead angle (the of helical blade 1
1,
2,
3And
4) having determined the shape and the casting performance of helical blade 1, can choose according to the concrete condition of local soil.Drill bit 4 is located when being used to dig pit below axis 3.
When using the spiral cutterhead of Tree Planting Earthdrill; Through axis 3 it is connected with Tree Planting Earthdrill; Hole digger drives the cutterhead spiral and moves downward, and the location drill bit is at first located, under the effect of moment of torsion and axial force; The cutterhead rotation is also moved by cutting edge 2 cutting soil vertically downward, and the soil under the cutting is thrown to hole along helical blade 1.
