Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-5 is please referred to, a kind of embodiment provided by the utility model: a kind of push pipe rotary drilling device, including pipe laying
1, described 1 one end of pipe laying is provided with spoke shape support frame 2, and positioning drill bit 3 is provided at 2 center of support frame, described fixed
Position drill bit 3 is structure as a whole with support frame 2, and 2 Right vertical of support frame is located in the pipe laying 1 and is provided with for laterally solid
Determine the mounting rack 4 of motor 5, the central axis of 5 output shaft of motor and pipe laying 1 is located along the same line, and pipe laying 1
Interior 5 left vertical of motor that is located at is provided with the mounting plate 6 for longitudinally fixed motor, and 5 output shaft of motor passes through mounting plate 6
It is connect by shaft coupling 7 with line shaft 8, the motor 5 is the variable-frequency motor with retarder, and the shaft coupling 7 is elastic shaft coupling
Device 7 can effectively weaken the impact force that motor 5 is subject to and play the role of protecting motor 5, and be provided with the shaft shoulder on line shaft 8
9, power shaft supporting frame 14 is provided between the shaft shoulder 9 and shaft coupling 7, and power shaft supporting frame 14 is spoke-like, line shaft
Support frame 14 can effectively support line shaft 8, prevent line shaft 8 from bent by impact force, in the power shaft supporting frame 14
It is equipped with self-lubricating copper sheathing 15 between 8 outer wall of wall and line shaft, there is good wearability, the 9 surface spaced set of the shaft shoulder
There are at least four gussets with holes 10 for being used to fix rotary digging blade 11, and gusset with holes 10 and rotary digging blade 11 are hinged, the rotation
