Set is internal to have thread bush internal thread hole, and external screw thread shaft part is threadedly coupled with thread bush internal thread hole, the power transmission shaft bottom tool
There is power transmission shaft external screw thread shaft part, power transmission shaft external screw thread shaft part is threadedly coupled with thread bush internal thread hole, is had inside the power transmission shaft
There is an interior post holes, there is cylinder plush copper at the top of the drill bit, in the insertion of cylinder plush copper in post holes, the drill bit middle part is uniformly distributed flat
Key, the drill bit middle part are uniformly distributed triangular key, have key connection groove inside the power transmission shaft, and flat key, triangular key insert key connect
In access slot, there is No.1 clasp internal thread hole inside the No.1 internal thread clasp, have inside No. two internal thread clasps
No. two clasp internal thread holes, No.1 clasp internal thread hole are threadedly coupled with power transmission shaft external screw thread shaft part, No. two clasp internal thread holes
It is threadedly coupled with power transmission shaft external screw thread shaft part, drill bit and transmission axis connection.
The drill bit bottom has optical axis section, and the optical axis pars infrasegmentalis welds knife rest, knife rest right side uniform welding knife
Head, the power transmission shaft top are connected with the chute in portal frame, in the drill bit insertion sandstone ground.
Beneficial effect：
In the insertion of cylinder plush copper in post holes, while playing positioning action, horizontal direction play, triangular key are also prevented from
In insert key link slot, contact surface is inclined-plane, and this can effectively disperse to rotate load, make stable connection, flat key is inserted as taper
Enter in key connection groove, contact surface is plane, consistency of thickness, bonding strength is become big, makes stable connection, and load is divided equally, and connects spiral shell
Line set is internal to have thread bush internal thread hole, has power transmission shaft external screw thread shaft part outside power transmission shaft, drill bit bottom has external screw thread
Shaft part, with being respectively provided with external screw thread outside thread bush internal thread hole, the internal thread hole covered by connection screw thread connects external screw thread shaft part
Together, there is No.1 clasp internal thread hole inside No.1 internal thread clasp, there are No. two clasps inside No. two internal thread clasps
Internal thread hole, No.1 clasp internal thread hole, No. two clasp internal thread holes and power transmission shaft external screw thread shaft part coordinate, and form double nut lock
Tightly, prevent connection screw thread set from vertical direction play occurs, make stable connection.
