The invention relates to a well drilling device for soil and general rock geology, in particular to a portable well drilling machine. It is mainly to solve the problems of space occupied by drilling rigs, labor consumption, large floor area, high cost, and the need to transmit the driving force to drive the main drill pipe, which makes the height of the construction space high, and it is impossible to complete drilling operations indoors. technical problem. The present invention comprises frame, and is provided with hydraulic mechanism on frame, and hydraulic mechanism is connected with sliding lifting frame, and frame is provided with slide rail, and sliding lifting frame is slidably connected in slide rail; There is a double seat cover on the box, the bottom of the double seat cover is connected with a spline shaft, and there is a locking cap on the spline shaft to lock with the gearbox; Drill pipes are movably connected between them, and the double-seat cover is threaded with a straight tooth lock holding top wire; the inside of the double-seat cover is provided with a rounded table, which is movably connected with a retainer, and the ring body of the retainer can fix the locking of the drill pipe. body.
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...
