Portable well-digging machine

Abstract

The invention relates to a well-digging device in soil or general rock geology, especially the light well drill. It mainly solves problems that the prior well drill is provided with large occupied space, large labor consumption, large occupied area and high cost; the driving main drilling bar transmitting power is needed so that the height of construction space is demanded highly and the well-digging work can not be accomplished in door. The invention comprises a rack. On the rack a hydraulic mechanism is set and a slide lifting rack is connected with the hydraulic mechanism. On the rack there is a slide rail, in which the slide lifting rack is connected. A gearbox is connected on the slide lifting rack and on the gearbox a double-seat sleeve is set. At the bottom of double-seat sleeve a spline shaft is set and on the spline shaft a locking cap is fixed with the gearbox. In the double-seat sleeve a straight-tooth arc hug is set. A drill bar is set between straight-tooth arc hugs actively and a screw for straight-tooth locking hug passes through the double-seat sleeve. In the double-seat sleeve a reversed circle platform is set, which is connected with a protective ring actively. On the ring body of protective ring the locking body of drill bar can be fixed.

Description

technical field [0001] The invention relates to a well drilling device for soil and general rock geology, in particular to an improvement on the structure of a portable well drilling machine used in a narrow space. Background technique [0002] In the vast rural areas of our country, drinking water for people and livestock mainly depends on machine-driven wells, which are also sources of water for non-gravity irrigation of farmland. In addition, water for urban and rural civil engineering projects generally relies on machine-driven wells. At present, the well-drilling tools used for well drilling are mostly composed of a derrick, a motor, a mud pump, and a drill pipe. It is necessary to add a large amount of water to make mud, and then pump out the mud, so that the work goes round and round to complete the well drilling operation. But there is the well-drilling equipment volume heavy in the way of this drilling machine well, the drawback of moving difficulty. Chinese paten...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a portable well drilling machine, which mainly solves the problems of the space occupied by the well drilling machine in the prior art, the labor cost and the large floor area, resulting in an increase in the comprehensive cost of well completion; It solves the technical problems that all drilling rigs need to transmit the driving force to drive the main drill pipe, so that the height of the construction space is high, and it is impossible to complete the drilling operation indoors.
