Abstract
The utility model relates to the technical field of engineering machinery belonging to the drilling tool of an auger driller, particularly a spiral percussion drill. The conventional auger is only suitable for the construction on softer geology due to auger drilling, when harder rock is met during the construction, the drilling cannot be continued, the application range and operating efficiency of the auger are seriously influenced. The spiral percussion drill comprises a rotary main shaft, a main shaft joint, an auger stem body, an impactor joint, a spiral sheath and an impactor; the rotary main shaft is connected to the external thread at the top of the main shaft joint at the top of the auger stem body via the internal thread at the connection end; the tail end of the auger stem body is connected to the external thread at the top of the impactor joint at the top of the impactor via the internal thread, the spiral sheath is welded on the stem body of the impactor, the spiral blade on the auger stem body and the spiral sheath of the impactor are in a butt joint; both of the rotary main shaft and the auger stem body are in a hollow structure, the impactor is assembled with a flat impact drill bit. The drill is wide in application and can be used in pile hole construction in various geological conditions.
Description
Technical field
The utility model relates to technical field of engineering machinery, belongs to the drilling tool of spiral drilling machine, specifically a kind of spiral Churn drill.
Technical background
Spiral drilling machine is base and based process equipment, is applicable to the pile foundation construction of all kinds of object of construction production such as preformed pile, castinplace pile, underground connection wall, reinforcing soft foundation.Traditional spiral drilling machine because the working position of drilling tool is a helical blade type, adopts spiral to creep into, and only is applicable to softer geology construction, in case run in the work progress than hard rock then blade wear is serious, can't creep into.This defective has seriously influenced the scope of application and the operating efficiency of spiral drilling machine.
Summary of the invention
The purpose of this utility model provides a kind of spiral Churn drill, with solve inefficiency, parts that spiral drilling machine occurs under than hard place matter condition easy to wear, meet problems such as hard formation can't creep into.
The technical solution of the utility model is: the spiral Churn drill is made up of rotary main shaft, main shaft joint, the auger body of rod, impactor joint, spiral sheath, impactor; Rotary main shaft is connected with the external screw thread at the main shaft joint top at auger body of rod top by the link internal thread; Auger body of rod afterbody is connected by the external screw thread of internal thread with the impactor joint top at impactor top, and spiral sheath is welded on the impactor body of rod, and the helical blade on the auger body of rod docks with the spiral sheath of impactor; Rotary main shaft, the auger body of rod all are hollow structures; Impactor is fitted with flat formula and impacts bore bit.
The utility model has the advantages that comparing the working position with the conventional helical drilling rod is down-the-hole air hammer, adopt down-the-hole to creep into, can't creep into when having avoided meeting rock and problem that parts are easy to wear.Easy accessibility, simple in structure; Broken rock deslagging is effective, can effectively improve construction quality; The pore-forming efficiency height is not prone to problems such as boring the hole of collapsing; Applied widely, be convenient to the pile hole construction of rig under various geological conditionss.
Description of drawings

Fig. 2 is a work schematic diagram of the present utility model
The specific embodiment
1 rotary main shaft, 2 main shaft joints, the 3 auger bodies of rod, 4 impactor joints, 5 spiral sheath, 6 impactors among the figure.
From Fig. 1, Fig. 2 as can be known, the spiral Churn drill is made up of rotary main shaft 1, main shaft joint 2, the auger body of rod 3, impactor joint 4, spiral sheath 5, impactor 6; Rotary main shaft 1 is connected with the external screw thread at main shaft joint 2 tops at the auger body of rod 3 tops by the link internal thread; The auger body of rod 3 afterbodys are connected by the external screw thread of internal thread with impactor joint 4 tops at impactor 6 tops, and spiral sheath 5 is welded on impactor 6 bodies of rod, and the helical blade on the auger body of rod 3 docks with the spiral sheath 5 of impactor 6; Rotary main shaft 1, the auger body of rod 3 all are hollow structures; The flat formula of impactor 6 equipped (routine) is impacted bore bit; The auger stem external diameter is 400～800mm, and pitch is 330～695mm.
When creeping into operation, utilize top down-the-hole air hammer impact energy fractured rock, rotary main shaft 1 revolution, the high pressure wind energy enters in the impactor 6 by each parts hollow structure, and broken waste residue is discharged outside the boring by the blade and spiral sheath 5 revolutions of auger stem 3.
