Abstract

The invention discloses a free-falling body type well drilling machine. The free-falling body type well drilling machine comprises a power rod, a hollow hammer, a rotary plate, a power mechanism, a power arm and a well tube, wherein the lower end of the power rod is bulged with an impact boss; an impact hole is formed in the lower part of the impact boss; the hollow hammer is arranged on the power rod in a up-down sliding manner in a sleeving mode; the rotary plate is I-shaped, and arranged at the upper end of the power rod; the power mechanism is used for driving the rotary plate to rotate; the upper end of the power arm is hinged in a groove of the rotary plate, and fixedly provided with a push rod which is positioned at the rear side, along a rotary direction of the rotary plate, of the power arm; the lower end of the power arm is connected with the hollow hammer by a stay cord; a stay cord guide plate is further arranged on the power rod in the sleeving mode; two guide devices are symmetrically arranged at the two sides of the stay cord guide plate; the upper part of the well tube is movably arranged in the impact hole in the sleeving mode; and the lower end of the well tube is pointed, and a plurality of water inlets are formed in the lower part of the well tube. The free-falling body type well drilling machine is simple in structure, convenient to assemble and carry, firm and durable in use, convenient to open, and labor-saving.

Description

technical field [0001] The invention relates to the field of excavating devices, in particular to a free-fall well drilling machine. Background technique [0002] Drinking water for people and animals in the vast rural areas of my country is mainly obtained by digging wells. Currently known well drilling machines are large in size, heavy in weight, complex in structure, troublesome in disassembly and assembly, and often require tractors, cranes, etc. to be transported. Trouble, thereby greatly reducing the flexibility of drilling machine use. Therefore, most places in rural areas can only dig wells by manpower, which has high labor intensity and low work efficiency. [0003] The information disclosed in this Background section is only for enhancing the understanding of the general background of the present invention and should not be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in...
