Generally, pipes are buried underground for various underground facilities, and for this purpose, drilling equipment according to various construction methods is used.

Conventional propulsion methods include a terra rudder method and a hydraulic jack method. The terra rudder method is a method of injecting steel pipes by squeezing with compressed air, and suitable for propulsion of small diameter steel pipes. The propulsion post-excavation method, the hydraulic jack (JACK) method is a small diameter, large diameter steel pipe when the propulsion construction of earth and earth excavation, earth excavation by manpower in the steel pipe as the basic process, the post drilling, pre-excavation after-parallel parallel method to be.

However, the propulsion method according to the prior art as described above is no longer propelled by the excavation ground conditions such as rock extrusion during the propulsion process, and the long-distance excavation propulsion is impossible because the steel pipe propulsion direction can not be adjusted when excavating more than 60M There is a problem.

In addition, there are risk factors such as subsidence and cracking of the ground because soil excavation and excavation of earth and sand are carried out by manpower in the steel pipe during the excavation and promotion. There is also a problem.

The present invention was devised to solve the above problems of the prior art, it is possible to adjust the direction of propulsion of the head portion by grasping the working state of the head portion in front of the cutter mounted during excavation and propulsion, which enables more precise long-distance excavation construction. Its purpose is to provide an excavator that can adjust the tip to simultaneously carry out excavation and promotion, such as labor reduction and risk removal, by automating the entire process from excavation to excavation of soil.

Preferably, in consideration of the connection structure and the propulsion process of the hinge 10 ', the head portion 10 can be rotated up and down 6cm.

In addition, when the up and down slope of the steel pipe portion 20 changes during excavation and propulsion, the scale of the Dutch level 53 is changed by the water pipe 52 connected to the tip of the steel pipe portion 20, and thus the propulsion direction needs to be adjusted. There is also this, by turning the adjustment lever 62 in the same manner as above to adjust the propulsion direction by rotating the head portion 10 up and down.

The auger screw 31 is rotated by a driving motor built in the driving main body 30 to move forward during the excavation propulsion, and the excavation propulsion is performed while the cutter 11 of the head part 10 connected thereto rotates. Water is sprayed onto the cutter 11 through a nozzle installed inside the steel pipe 20 during propulsion to prevent a temperature increase of the cutter 11.

In addition, during excavation and propulsion, the lubricant is supplied through the lubrication hole 21a of the lubricating oil supply pipe 21 installed on the outside of the steel pipe 20 to reduce friction between the outer surface of the steel pipe 20 and the excavation ground. .

On the other hand, the earth and sand according to the excavation is introduced into the steel pipe portion 20 through the soil inlet opening (10a, 10b) of the head portion 10 and transported to the rear in the steel pipe portion 20 by the rotation of the auger screw 31, the earth and sand It is discharged to the outside through the discharge port 32a.

Then, the excavated excavated soil is conveyed to the rear of the drive main body 30 by the horizontal belt conveyor 71, and again by the inclined belt conveyor 72 to the dump truck (3) outside the work tool (1) The earth and sand are taken out in parallel with the excavation and propulsion (S106).

Of course, a plurality of steel pipes are continuously joined and connected according to the excavation propulsion length, and a plurality of screws are connected to adjust the length of the auger screws 31 (S107).

As described above, the excavation propulsion operation and the connection of the steel pipe are repeated (S108), when the head portion 10 penetrates the reaching opening 2, the head portion 10 is pulled out of the reaching opening 2 (S109), and in the drilling opening The steel pipe part 20 is connected to a plurality of steel pipes in series.

As described above with reference to the drawings illustrating an excavator capable of adjusting the tip according to the present invention, the present invention is not limited by the embodiments and drawings disclosed in the present specification and various modifications by those skilled in the art within the scope of the technical spirit of the design Of course, modifications can be made.
