Abstract
The present invention provides a drill assembly that includes a drill for drilling rock, a support for supporting the drill, and a valve for releasably securing the support and drill together. The valve is adapted to receive a fluid from a pump means and controllably provide the drill and the support with the fluid for operation of the drill and the support.
Claims19
A drill assembly comprising a drill for drilling rock, a support for supporting the drill, a valve for releasably securing the support and drill together, whereby, in use, the valve receives a fluid from a pump that supplies fluid to the drill assembly and receives fluid from the drill assembly and controllably provides the drill and the support with the fluid for operation of the drill and the support, wherein the pump is in fluid communication with the valve, the valve is in fluid communication with the drill, the valve is in fluid communication with the support, and the drill is in fluid communication with the pump, wherein the drill has three modes of operation, a forward mode wherein a force exerted through a drill bit drives the drill bit forward, a neutral mode wherein no force is exerted through the drill bit, and a reverse mode wherein the drill is rotated in a reverse direction to decouple the drill from the drill bit.
A drill assembly comprising:
- a drill for drilling rock;
- a support for supporting the drill;
- a valve for releasably securing the support and drill together;
- and
- a pump to deliver fluid to, and receive the fluid from the drill;
- wherein while in use the valve receives a fluid from the pump and controllably provides the drill and the support with the fluid for operation of the drill and the support;
- and
- wherein the pump is in fluid communication with the valve, the valve is in fluid communication with the drill, the valve is in fluid communication with the support, and the drill is in fluid communication with the pump;
- and
- wherein the drill has three modes of operation, a forward mode wherein a force exerted through a drill bit drives the drill bit forward, a neutral mode wherein no force is exerted through the drill bit, and a reverse mode wherein the drill is rotated in a reverse direction to decouple the drill from the drill bit.
A drill assembly comprising:
- a drill for drilling rock and having a drill inlet and a drill outlet;
- a support for supporting the drill;
- a valve for releasably securing the support and the drill together such that they value operably supplies a fluid to the drill and the support and receives fluid from the drill and the support and wherein the valve comprises a three way joiner, wherein a first branch provides a first valve outlet in fluid communication with the drill inlet to allow fluid into the drill, a second branch, which is connected to a fluid source, and a third branch that includes a first valve inlet;
- wherein the drill outlet is in fluid communication with the fluid source such that the fluid flows through the drill outlet back to the fluid source;
- and
- wherein the drill has three modes of operation, a forward mode wherein a force exerted through a drill bit drives the drill bit forward, a neutral mode wherein no force is exerted through the drill bit, and a reverse mode wherein the drill is rotated in a reverse direction to decouple the drill from the drill bit.
