Abstract
The invention relates to a positive circulation simple drilling machine. A drill is positioned at the lowermost end of a drill rod; a triangular cage is made of section steel and is welded with a tooth tip; a water injection nozzle is arranged at the lowermost end of the drill rod; each section of drill rod is provided with a quick connector, and the drill rod is lengthened section by section with the increase of drilling depth; a twisting lever is screwed on the drill rod through a screw and moves upwards section by section with the increase of the drilling depth; the upper end of the drill rod is provided with a sealing rotating device; the drill rod in the upper section of the rotating device does not rotate, and the drill rod in the lower section of the rotating device rotates; and a hand winch hoists the drill rod through an oil silk rope and a pulley. The invention provides a drilling machine special for well drilling.
Description
One, technical field
The present invention relates to a kind of rig, the simple and easy rig of direct circulation that particularly a kind of drilling well is used.
Two, background technology
In the place of some poor transports, general drilling equipment fortune is not pass by, and at this moment, has a kind of light and handy artificial simple and easy rig that can lift just more convenient.
Three, summary of the invention
The present invention just provides so simple and easy rig of direct circulation
The present invention is achieved through the following technical solutions.
The simple and easy rig of a kind of direct circulation, drill bit is positioned at drilling rod bottom, makes the triangle cage type by shaped steel, is welded with crown on the triangle cage, and drilling rod is provided with water spout bottom; Every joint drilling rod is provided with snap joint, extends by joint along with the increase of drilling depth; On drilling rod, the strand thick stick moves up along with the increase of drilling depth strand thick stick piecemeal by screw tightening; The drilling rod upper end is provided with the sealed rotational device, and the joint drilling rod does not rotate on the rot, and following joint drilling rod rotates, and hand winch is by oil thread rope, and pulley lifts drilling rod.
Four, description of drawings
The invention will be further described below in conjunction with accompanying drawing:
Accompanying drawing is a structural representation of the present invention.
Among the figure: 1, drill bit, 2, drilling rod, 3, the strand thick stick, 4, snap joint, 5, the sealed rotational device, 6, flexible pipe, 7, slush pump, 8, tripod, 9, pulley, 10, hand winch.
Five, the specific embodiment
Accompanying drawing is a kind of specific embodiment of the present invention, and this embodiment drill bit 1 is positioned at drilling rod bottom, makes the triangle cage type by shaped steel, is welded with crown on the triangle cage, and drilling rod is provided with water spout bottom; Every joint drilling rod is provided with snap joint 4, extends by joint along with the increase of drilling depth; On drilling rod, strand thick stick 3 moves up along with the increase of drilling depth strand thick stick piecemeal by screw tightening; The drilling rod upper end is provided with sealed rotational device 5, and the joint drilling rod does not rotate on the rot, and following joint drilling rod rotates, and hand winch 10 is by oil thread rope, and pulley lifts drilling rod.
The present invention at first opens slush pump 7 in use, and jetting is sprayed from bit nozzle, and the artificial thereafter strand thick stick that rotates sinks drill bit, the mud flow mud pit in the hole, and post precipitation is sent in the hole by slush pump again, so repeatedly.
