So I improved the previous mining machine design with more structural stability and power.

011.png = Do you see the diamond superman shaped horizontal pole extending from the main vertical pole? That pole is retractable.

Do you see the grey circle below the horizontal drill? That is how the drill should be. Bigger in diameter.

Do you see the blue line vertical? That's actually just a rope.

 

So carrying that over to 022.png,

 

Let's say the moving machine with wheels is really moving a vertical scaffold. Like you see in construction sites.

The diamond horizontal pole follows up the scaffold by use of gears. So the height can be controlled vertically.

Then when it is fixed on a certain height, it can push horizontally the drill, so it creates friction, eats away at the protruding surface from the ground level.

 

And the blue line in a slope is actually the powerline/rope.

It should be much higher. But it just adjusts itself as the  drill moves up and down,

by a roller on the back. Which I forgot to draw. (It just rolls/winds the rope back and forth as is required)

Why is that needed when the protruding machine can handle the weight of the drill?

Because if to use induction motors, it would make the drill independent from power source and heavy.

So the rope can be just used as a weight alleviator,

or if to be feeding electricity to run the induction motors, then it could be a powerline.

 

Either way, it takes the load off the drill so the horizontal mechanism can focus on amplifying the power of the drill by pushing.

 

 

This is better than the last design because...

That has too many joints. It's inheritantly weak.

This is not limited by moving parts. Both in durability and control system adaptation.

It's a solid rigid piece that relies on a push.
