Rotary digging drill bit is a kind of construction technology of pore-forming operation in suitable building foundation engineering.It is widely used in the ground foundation construction work such as urban construction, highway bridge, skyscraper, the different drilling tool of cooperation, it is adapted to dry type（Short spiral）, or wet type（Rotary bucket）And rock stratum（Rock core drill）Pore-forming operation, rotary drilling rig has that installed power is big, output torque is big, axial compressive force is big, maneuverability, and efficiency of construction is high and multifunctional characteristics.Rotary drilling rig adapts to the soil-geological condition of China's most area, and range is wide, substantially can meet bridge construction, the use of the engineering such as tall building foundation plinth. and at present, rotary drilling rig has been widely popularized in various Grouting Pile Engineering of Drilling Hole.Therefore highly important meaning has technically been inquired in preparation of construction and conventional plain construction technology to rotary drilling rig.During construction, different drill bits are selected by following regulation according to different soil, geological conditions：Short spiral drill it is adaptable to more than level of ground water cohesive soil, silt, banket, medium closely knit above sand, weathered rock formation.Rock core augers is it is adaptable to gravelly soil, medium-hard rock and weathered rock formation.Rock core rotary bucket is it is adaptable to weathered rock formation and the rock having crackle.The rotary digging drill bit of current practice, pick is enclosed within the outside of blade although easy for installation, but easily comes off, thus affecting the normal work of equipment when using.
Content of the invention
The present invention provides and a kind of armored concrete rotary digging drill bit, holds caducous problem with the pick solving to propose in above-mentioned background technology.
Technical problem solved by the invention employs the following technical solutions to realize：The present invention provide and a kind of armored concrete with rotary digging drill bit it is characterised in that：Including auger spindle，The top of described auger spindle is provided with connection ring，It is provided with connecting post above described connection ring，It is provided with connecting hole in described connecting post，The bottom surface of described connection ring is provided with reinforcing plate，The opposite side of described reinforcing plate is fixed on auger spindle，Described auger spindle outer wall is provided with blade，Described blade is provided with positive stop lug boss，Described positive stop lug boss is annular，It is provided with pick in described positive stop lug boss，It is additionally provided with spacing block set on described blade，Described spacing block set is located in the middle of positive stop lug boss，The bottom surface of described pick is provided with the limited impression matching with spacing block set，Described pick outer wall is provided with spacing ring，Described spacing ring is located above positive stop lug boss，Described pick and positive stop lug boss are bolted，The bottom of described auger spindle is connected with stud，Described stud screw head is arranged below，The top of described screw head is provided with locating slot，The bottom of described stud is located in locating slot，It is cased with protection cylinder outside described auger spindle bottom，Described protection cylinder inner hollow，Described stud、The top of screw head is located in protection cylinder，Described protection cylinder inwall is provided with convex tendon，Described auger spindle is located at the top of convex tendon，Described screw head is located at the lower section of convex tendon.
The quantity of described reinforcing plate is 4, and circumference is equally spaced.
Described spacing ring is with diameter greater than positive stop lug boss diameter.
Beneficial effects of the present invention are：The technical program passes through to arrange positive stop lug boss on blade; and pick is placed in positive stop lug boss; effectively pick can be protected; prevent landing; positive stop lug boss can carry out quick location and installation with the cooperation of limited impression; spacing ring acts primarily as position-limiting action; pick is bolted on positive stop lug boss; fastening structure, and do not expose, handsome in appearance; the protective jacket of bottom can prevent screw head from coming off; implementation result is good, the connection acting as reinforcement connection ring and auger spindle of reinforcing plate, and structure is more firm.
