A Mechanism for Shallow Well Drilling

Abstract

The invention belongs to the technical field of well drilling, and particularly relates to a mechanism used for shallow well drilling. The mechanism comprises a ground soil pushing mechanism, a drill bit with a soil discharging function and an on-well pressure applying mechanism, wherein the ground soil pushing mechanism is mounted on the ground, the on-well pressure applying mechanism is mounted on the ground, and the drill bit with the soil discharging function is mounted on the on-well pressure applying mechanism. The on-well pressure applying mechanism applies pressure on a drill stem through the action of a threaded pressure applying mechanism, and the drill stem drives the drill bit to rotate; through the special design of drill bit blades, the drill bit can throw soil and gravels to the upper side of the drill bit, the soil and the gravels are transported by a soil discharging plate, the soil is conveyed outside a well mouth, and then the soil is manually transferred from the soil discharging plate to a soil heaping bucket; the sliding effect of guide rails is used for conveying the soil heaping bucket containing the soil to a place away from the well mouth, and then a swing arm swings to turn the soil to a soil heap. The whole process of the overall mechanism is semi-automatic, and a certain practical effect is achieved.

Description

Technical field [0001] The invention belongs to the technical field of drilling, and in particular relates to a mechanism for shallow well drilling. Background technique [0002] At present, when drilling deep wells, the crushed rock and soil drilled by the drill bit are impacted by water to form a mixture of water, soil and crushed rock, and then sucked away by the pipeline through the pump; when drilling shallower wells, the integrated drill pipe and drill bit are used. equipment, its drill pipe is like a thread, and the mud and broken rock can be discharged with the "thread" during the rotation of the drill bit, but for drilling shallower and larger diameter wells, it is difficult to find as mentioned above If the drilling equipment uses a pump to suck the drilled earth and broken rock, then the equipment used will be a great waste for drilling shallow wells, and the relative cost is very high, which is very uneconomical. [0003] The present invention designs a mechanis...
