Dust collection system for a machine
A dust collection tube arrangement is provided. The tube arrangement includes an outer tube and an inner tube. The outer tube and the inner tube have a hollow configuration. The inner tube has a diameter lesser than that of the outer tube. The inner tube moves fore and aft with respect to the outer tube. The outer and inner tubes provide a passage for dust and airflow along with adjustable length of tube arrangement based on a position of the inner tube with respect to the outer tube.
1. A dust collection tube arrangement, the tube arrangement comprising:
an outer tube having a hollow configuration; and
an inner tube having a hollow configuration, the inner tube having a diameter lesser than that of the outer tube, the inner tube configured to move fore and aft with respect to the outer tube;
wherein the outer and inner tubes are configured to provide a passage for dust and airflow, such that a length of the tube arrangement is adjustable based on a position of the inner tube with respect to the outer tube;
wherein the tube arrangement is associated with a drill mast of a roof bolter, the outer tube being attached to the drill mast and the inner tube being attached to an extendable portion; and
wherein the movement of the inner tube within the outer tube is based on a movement of the drill mast.
2. The tube arrangement of claim 1 further comprising a sealing means provided at an interface of the inner tube and the outer tube.
3. The tube arrangement of claim 2 , wherein the outer and inner tubes are made of a first material and the sealing means is made of a second material, the second material being different from that of the first material.
4. The tube arrangement of claim 1 , wherein one end of each of the inner and outer tubes includes a nozzle for connection with a dust inlet hose and a dust outlet hose.
5. The tube arrangement of claim 1 , wherein the tube arrangement is associated with a drill boom segment of a roof bolter, the outer tube being attached to a main drill boom and the inner tube being attached to an extendable portion.
6. The tube arrangement of claim 5 , wherein the movement of the inner tube within the outer tube is based on a movement of the main drill boom.
7. The tube arrangement of claim 1 , wherein a length of the inner tube is equal to or greater than a length of the outer tube.
8. A dust collection system comprising:
an inner tube having a hollow configuration;
an outer tube having a hollow configuration, a diameter of the outer tube being more than that of the inner tube; and
a sealing means positioned at an interface of the inner tube and the outer tube, the sealing means being provided such that the inner tube is slidable within the outer tube;
wherein a combination of the inner and outer tubes provides a contiguous passage having a variable length for dust and airflow;
wherein the dust collection system is associated with a drill mast of a roof bolter, the outer tube being attached to the drill mast and the inner tube being attached to an extendable portion; and
wherein the sliding of the inner tube within the outer tube is based on a movement of the drill mast.
9. The system of claim 8 , wherein the outer and inner tubes are made of a first material and the sealing means is made of a second material, the second material being different from that of the first material.
10. The system of claim 8 , wherein one end of each of the inner and outer tubes includes a nozzle for connection with a dust inlet hose and a dust outlet hose.
11. The system of claim 8 , wherein the dust collection system is associated with a drill boom segment of a roof bolter, the outer tube being attached to a main drill boom and the inner tube being attached to an extendable portion.
12. The system of claim 11 , wherein the sliding of the inner tube within the outer tube is based on a movement of the main drill boom.
13. The system of claim 8 , wherein a length of the inner tube is equal to or greater than a length of the outer tube.
