Description
Technical field
The invention belongs to bore indigenous equipment technical field, and in particular to a kind of pit-picker double helix brill earth boring auger head.
Background technique
Pit-picker is mountainous region, and Qiu Ling, Gullied afforestation, apply fertilizer the special-purpose machinery quickly digged pit.Pit-picker allows people
Freed from heavy manual labor, be widely used in planting trees, plantation fruit-bearing forest, hedge and autumn to applying fruit trees with fertilizer etc.,
The digging apparatus of pit-picker is drill bit, and drill bit lateral wall is spiral, and bottom is tip, and tip matches injection ground with spiral, into
Row is digged pit.
Existing technology has the following problems:
1, the head of existing pit-picker is flat structure, and drill bit is the same similar to nail, can only be drilled out when boring soil small
Hole, no normal direction depth of soils are bored dynamic, and causing the head of pit-picker to be beaten not, into boring in frozen soil depth is limited, and drill bit easily occurs
It skids, influences to bore native efficiency；
2, not in same axis, blade is led with using the time to increase vulnerable to abrasion for existing pit-picker drill bit and blade
Native low efficiency is beaten in cause；
3, existing pit-picker is not unearthed outward during digging pit, and stays in soil in hole always, can not directly transplant.
Summary of the invention
To solve the problems mentioned above in the background art.The present invention provides a kind of pit-picker double helixs to bore earth boring auger
Head has the characteristics that bore native high-efficient and takes soil convenient.
To achieve the above object, the invention provides the following technical scheme: a kind of pit-picker bores earth boring auger head with double helix, including
Drill bit column, the lateral wall of the drill bit column are fixed with single-screw blade, and the bottom of the upper single-screw blade is interleaved with
The lateral wall of lower list helical blade, lower single helical blade and the drill bit column is integrally formed, the upper single-screw blade
The band soil square position fixed there are two same size corresponding with lower single bottom of helical blade, the bottom of two band soil square positions
Fixed there are two boring the blade in portion, and two same axis for boring ground blades are equipped with drill bit, the drill bit and the brill
The bottom of head column is fixedly connected.
Preferably, the upper single-screw blade between the upper and lower away from for 200mm.
Preferably, lower single helical blade between the upper and lower away from for 100mm.
Preferably, the length of lower single helical blade is the one third of the upper single-screw blade.
Preferably, the spiral gradient of the upper single-screw blade and lower single helical blade is respectively less than 15 degree.
The top of the upper single-screw blade and the junction of the drill bit column are welded with baffle.
The lateral wall of the drill bit offers screw thread.
Compared with prior art, the beneficial effects of the present invention are:
1, drill bit is helical structure, and on brill ground, process drill bit bores ground depth and increases, and the native efficiency of brill is fast, upper single-screw blade
The lower single helical blade rotation of cooperation, upper single-screw blade is not in get rid of soil during rotation, and lower list helical blade has
The fast effect of soil, mating band soil square position can will bore the soil in hole and propose, keep boring the cleaning in hole, facilitate brill hole subsequent
It uses；
2, the spiral part gradient of upper single-screw blade and lower single helical blade is small, plane is similar to, during boring soil
Eased off soil will not be fallen into hole, and it is big to solve the existing earth borer material spiral part gradient, and soil falls when boring soil
It drops down onto hole, increases the problem of boring native difficulty；
3, the matched brill ground blade of drill bit is fixed on same axis, and when boring ground, the rotation that ground blade is subject to is bored in dispersion
Turn the stress impact in direction, reduces the abrasion for boring ground blade.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Embodiment 1
Fig. 1-6 is please referred to, the present invention is the following technical schemes are provided: a kind of pit-picker bores earth boring auger head with double helix, including bores
Head column 1, the lateral wall of drill bit column 1 are welded with single-screw blade 2, and the bottom of upper single-screw blade 2 is interleaved with lower single spiral shell
The lateral wall of vane piece 3, lower list helical blade 3 and drill bit column 1 is welded and fixed, upper single-screw blade 2 and lower single helical blade 3
The corresponding native square position 5 of band for being welded with two same sizes in bottom, fixed there are two boring the blade in the bottoms of the native square position 5 of two bands
6, and two same axis for boring ground blade 6 are equipped with drill bit 4, drill bit 4 is fixedly connected with the bottom of drill bit column 1, bores earthing knife-switch
Piece 6 and drill bit 4 are in same axis, and when boring ground, the axial stress impact that ground blade 6 is subject to is bored in dispersion, reduce and bore ground blade 6
Abrasion.
In the present embodiment: when boring soil, drill bit 4 contacts ground, and drill bit 4 is pierced with bench drill earthing knife-switch piece 6 to underground, upper list
The lower single helical blade 3 of the cooperation of helical blade 2 rotates, and upper single-screw blade 2 is not in get rid of soil during rotation, lower single-screw
Blade 3 has the effect of being unearthed fast, terminates after boring soil, lifts drill bit column 1, the native square position 5 of band will bore the soil in hole and propose, guarantor
The cleaning bored in hole is held, brill hole subsequent use is facilitated.
Specifically, upper single-screw blade 2 between the upper and lower away from for 200mm；Between the upper and lower away from the upper single-screw blade 2 for 200mm,
Be not in get rid of soil during boring soil, effectively reduce soil and loosen, prevents from boring and cheat internal soil accumulation, be conducive to mention
Height bores hole depth.
Specifically, lower list helical blade 3 between the upper and lower away from for 100mm；Lower single helical blade 3 that spacing is 100mm is turning
During dynamic, soil is deposited in the wall of lower single helical blade 3, and can promote lower single helical blade 3 mentions native efficiency, side
Just the soil bored in hole is carried out mentioning soil after boring soil.
Specifically, the length of lower list helical blade 3 is the one third of upper single-screw blade 2；Lower list helical blade 3 is used for
Quick drill is native and mentions soil, and upper single-screw blade 2 loosens the soil for boring soil, and the two cooperation carries out boring soil and proposes the work of soil.
Specifically, the spiral gradient of upper single-screw blade 2 and lower single helical blade 3 is ten degree；Upper 2 He of single-screw blade
The spiral part gradient of lower list helical blade 3 is small, is similar to plane, and eased off soil will not be fallen into hole during boring soil,
It is big to solve the existing earth borer material spiral part gradient, soil is fallen in hole when boring soil, is increased and is bored native difficulty
Problem.
Specifically, the top of upper single-screw blade 2 and the junction of drill bit column 1 are welded with baffle 7；Upper single-screw blade
