Abstract

The utility model relates to a water well drilling machine which is provided with a chassis frame, wherein the front part of the chassis frame is provided with a well drilling bracket and a driving box, the middle part is provided with a diesel engine and a winch, and the rear part is provided with a slurry pump. The well drilling machine is provided with a plurality of hollow drill rods which can be connected through screw threads, one end of each hollow drill rod is connected with a hose which is connected with the slurry pump, and the other end is connected with a hollow drill bit. When a well is drilled, water is infused into a drilled hole, soil which is drilled out by the drill bit is mixed with the water into slurry, and the slurry can be pumped out by the slurry pump through the hollow drill rod, so that the drill bit can quickly descend. When the utility model is used for drilling a well, the well is drilled by the drill bit, the mixture of slurry which is drilled out and water can be pumped out to the ground by the slurry pump in time, so that the efficiency for drilling wells is high, and one well can be drilled in a short period.

Description

A kind of well well sinker

The utility model relates to a kind of civilian well well sinker.

Will be at the ground sink wells to the underground deep hole of getting.In the prior art, at the used well sinker of the place of silt particle soil property well-digging the short tubular big and heavy stone head close with the diameter of well head arranged, there is cutting edge big and heavy stone head lower end, and one way valve is arranged at the bottom in the big and heavy stone head.During well-digging, with the big and heavy stone head intermittently to underground big and heavy stone, big and heavy stone head of every big and heavy stone advances one section to the degree of depth, silt particle soil enters in the short pipe of big and heavy stone head by one way valve, and repeatedly behind the big and heavy stone, deepen gradually in the hole, silt particle soil can be filled the short pipe of big and heavy stone head, propose the big and heavy stone head and draw off the interior silt particle soil of big and heavy stone head, continue again to the depths big and heavy stone, up to the degree of depth of water outlet.This well sinker well-digging efficient is low, and it is longer to beat the used time of a bite well.

The purpose of this utility model is in order to overcome above-mentioned deficiency, to propose a kind of high civilian well well sinker of well-digging efficient that is applicable to silt particle soil property ground.

The utility model is realized with the following method.

Invention scheme of the present utility model is to connect a hollow drill bit with hollow drilling rod, drive hollow boring bit with hollow drill during well-digging and rotate drilling bore hole on the ground, water filling in the hole in the time of boring, allow the earth under the bit drills and the water of injection be mixed into mud, by hollow boring bit and hollow drill mud is extracted out ground with slush pump, it is underground that drill bit is pierced fast, reaches the degree of depth of water outlet.

For realizing the foregoing invention scheme, the well well sinker has square frame shape that the sole of road wheel is arranged, there is driving box the sole front portion and vertically stands on the drilling well support of the top of driving box, the sole and also has diesel engine, winch and reciprocating type mud pump with plunger, and the well well sinker also has many available tubular hollow drill and the hollow boring bits that are threaded.The slush pump inlet is connected with mud hose, and there is pulley the upper end of drilling well support, the steel wire penetrating pulley of winch, and wire rope one end has suspension hook.The outer wall of hollow drill axially has key pin, there is one to be to drive drilling rod in the hollow drill, an end that drives drilling rod has external screw thread, the other end that drives drilling rod links to each other with the other end of mud hose with the rotary dynamic seal device, one end of other hollow drills has the internal thread that matches with the external screw thread that drives the drilling rod lower end, the other end has the external screw thread that matches with the internal thread of one end, have the outer wall of internal thread one end to have outside the annular at other hollow drills and bind round, hollow drill can connect together with the screw thread at two ends.Driving box is the lineal hexahedral case, the through hole that can insert hollow drill is arranged on the vertical axis of driving box, the driving tube coaxial with through hole arranged in the through hole, the driving tube inwall axially has the key pin that matches with the axial key pin of hollow drill outer wall, the dynamic power shaft in the driving box outside, power input shaft links to each other with driving tube in the driving box by the transmission device in the driving box, when power input shaft rotates, can drive the driving tube rotation in the driving box.When the driving drilling rod is inserted in the driving tube,, when driving tube rotates, can drives and drive the drilling rod rotation because the outer wall of driving tube inwall and driving drilling rod all has axial key pin.One end of hollow boring bit has the internal thread that matches with the external screw thread of hollow drill.The power output shaft of diesel engine can drive winch by clutch and transmission device respectively, and driving box and slush pump rotate respectively.

During use, the sole support on the ground, the suspension hook of winch is hung in the junction that drives between drilling rod and the mud hose, rise suspension hook, the driving drilling rod of slinging, make and drive the driving tube that drilling rod passes driving box, on the external screw thread that drives the drilling rod lower end, link to each other with the internal thread of drill bit with screw thread, with winch drilling rod is put down, make drill bit support ground, drive driving box and slush pump rotation work with diesel engine, drill bit can get out circular hole on ground, to the hole water filling, slowly putting winch descends by deadweight by hollow drill, drill bit gets out with silt particle soil and the water that injects and is mixed into mud in the hole, mud passes through hollow boring bit, drive drilling rod and mud hose and be retracted to ground with slush pump, drill bit can descend to the depths rapidly because of the silt particle soil that extraction gets out and get out wellhole, in the time of near the upper end that drives drilling rod drops to driving box, can not descending again, stopping driving box rotating, mention the drill bit that drives hollow drill and connect together with winch, unload hollow boring bit, another root hollow drill is connected between driving drilling rod and the hollow boring bit with screw thread, slowly putting winch again descends by deadweight by hollow drill, allow driving box drive and drive the drilling rod rotation, continue to the wellhole water filling, drill bit can continue deeply, increase the radical of hollow drill as stated above one by one, can make wellhole deepen the degree of depth gradually up to water outlet.

The utility model the time is to get out wellhole with drill bit in well-digging, and the silt particle that gets out mixes in time with water extracts ground out with slush pump, makes drill bit deep easily, so the speed of digging a well is fast, efficient is high, it is very short to beat the used time of a bite well.
