Abstract
The utility model relates to a down-the-hole drill, comprising a connecting pipe, a pipe joint, an upper mud chamber, a lower mud chamber, a shell body and a drill bit. A submersible electric motor and a speed changing driving device are arranged between an upper mud chamber and a lower mud chamber, the drill bit is driven by the submersible electric motor directly, the drill bit is provided with a flow guiding rotary wing, and the lower end of a driving shaft arranged between the speed changing driving device is provided with a mud inlet channel and a mud spraying channel. When the utility model is in the drill operation time, dynamic force is submerged in a bottom hole directly to work, and material is saved, dynamic force consumption is reduced, and accidents of hole deviation and collapse are prevented, and thereby, the quality and the efficiency of well drilling are improved.
Description
The utility model relates to a kind of driller capable of diving in well.
It is many that existing drilling machinery generally all exists the equipment of taking, power drain is big, bit speed is slow, and phenomenons such as hole deviation and landslide easily take place in the well-digging process, this is because conventional drilling machinery generally drives kelly bar by the brill dish, link to each other with round bur bar machine by kelly bar again and drive drill bit then and execute brill, increase with well depth, required round bur bar increases, the also corresponding increasing of driving force that the brill dish consumes, the growth of power transmission line simultaneously, the drill pipe wobbling scope strengthens, may cause the generation of hole deviation even landslide phenomenon, this has just directly influenced drilling quality and drilling efficiency.
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and operation is reliable, and economical with materials can improve the driller capable of diving in well of drilling quality and drilling efficiency.
The purpose of this utility model is achieved in that it comprises tube connector, union, upper and lower slurry chamber, housing and drill bit, it is characterized in that between upper and lower slurry chamber, being provided with the submersible electric motor and the speed-changing driving device of direct driving drill bit, drill bit is provided with the water conservancy diversion rotor, the passage that is provided with into, whitewashes of the driving shaft lower end between speed-changing driving device and the drill bit.
The utility model drives drill bit indirectly with brill dish in the existing equipment and executes the brill mode and change into and directly drive drill bit by submersible electric motor and speed-changing driving device and execute brill, eliminated the drill bit swing, make unbearable being consistent, hole deviation and landslide accident have been avoided, again because saved brill dish and kelly bar, thereby saved material, reduced power consumption, simultaneously, drill bit is provided with the water conservancy diversion rotor, can dredge mud effectively, and the passage work that makes into, whitewashes is smooth and easy, the assurance drill bit is executed brill smoothly, thereby has improved the quality and the efficient of drilling well.
Below in conjunction with accompanying drawing embodiment of the present utility model is done to describe:
Fig. 1 is the structural representation of the utility model embodiment.
With reference to Fig. 1, the utility model comprises tube connector (1), union (2), upper and lower slurry chamber (3,6), housing (13) and drill bit (9), at upper and lower slurry chamber (3,6) be provided with the submersible electric motor (4) and the speed-changing driving device (5) of direct driving drill bit (9) between, drill bit (9) is provided with water conservancy diversion rotor (10), the lower end of driving shaft (14) passage (11 that is provided with into, whitewashes, 7,8).
During drillng operation, introduce submersible electric motor (4) from ground with three-phase power line (15), drive drill bit (9) through speed-changing driving device (5) by driving shaft (14) and execute brill, meanwhile, ground slush pump enters slurry chamber (3) from tube connector (1) through union (2) with mud, passes through feed pipe for mortar (12) again mud is delivered to down slurry chamber (6), and mud enters slurry channel (7) by the stock inlet (11) of driving shaft (14) lower end, by mouth spray (8) ejection, cooperate drill bit (9) operation again.Water conservancy diversion rotor (10) on the drill bit (9) can be dredged mud effectively, and the passage (11,7,8) that makes into, whitewashes work is smooth and easy, and assurance drill bit (9) is executed brill smoothly, thereby has improved the quality and the efficient of drilling well.The utility model is rational in infrastructure, and dependable performance is with low cost, can be widely used in the drilling well industry.
