Design a prototype device for unblocking drill holes in mining

Job ID: 36273481

Budget: $750 – $1,500 AUD

I would like an prototype design for a device for unblocking drill holes in underground mining. The device is deployed into a drill hole where it utilizes a small light weight hydraulic cylinder to fee up holes blocked by rocks.

I would like a first pass design made up based on some drawings I have attached. CAD drawings, possibly 3D renders also.

I need a talented Engineer/Designer that has some creative ideas on how this product could work. Will require some research or prior knowledge on different types of hydraulic cylinders
