Abstract

A drilling unit, comprising a chassis (3, 4) and a drilling machine (1, 2) arranged in front of the same, the chassis encasing an engine-house (8), in which an engine (9) is arranged as well as at least one cooler (14) and at least one fan (15), the drilling unit comprising at least one partition wall (17) that divides the engine house (8) into a first part (18), which accommodates the engine (9), and a second part, which accommodates said cooler (14) and fan (15), and that the partition wall (17) extends transverse to the longitudinal direction of the chassis and divides the engine house (8) into a front part (18) and a rear part (19). The first part (18) of the engine house (8) forms the front part and the second part (19) of the engine house (8) forms the rear part.

Claims

1. Drilling unit, comprising a chassis (3, 4) and a drilling machine (1, 2) arranged in front of the same, the chassis encasing an engine house (8), in which an engine (9) is arranged as well as at least one cooler (14) and at least one fan (15), the drilling unit comprising at least one partition wall (17) that divides the engine house (8) into a first part (18), which accommodates the engine (9), and a second part, which accommodates said cooler (14) and fan (15), and that the partition wall (17) extends transverse to the longitudinal direction of the chassis and divides the engine house (8) into a front part (18) and a rear part (19), characterized in that the first part (18) of the engine house (8) forms the front part and that the second part (19) of the engine house (8) forms the rear part.

2. Drilling unit according to claim 1, characterized in that the partition wall (17) is at least partly air-proof.

3. Drilling unit according to claim 1, characterized in that the partition wall (17) is completely air-proof.

4. Drilling unit according to claim 1, characterized in that the partition wall (17) forms a substantially air-proof bulkhead between the first and second parts (18, 19) of the engine house (8).

5. Drilling unit according to claim 1, characterized in that the partition wall (17) abuts closely against the chassis along the inner circumference thereof.

6. Drilling unit according to claim 1, characterized in that the chassis (3, 4) in the part that encases the second part (19) of the engine house (8) is provided with at least one air inlet opening (20).

7. Drilling unit according to claim 6, characterized in that said at least one air inlet opening (20) is arranged in at least one of the side walls or roof of the chassis (4).

8. Drilling unit according to claim 7, characterized in that said air inlet opening (20) is arranged both in the side walls and the roof.

9. Drilling unit according to claim 1, characterized in that it comprises means for the ventilation of the first part of the engine house.

10. Drilling unit according to claim 9, characterized in that said means comprises an exhaust-gas-driven ejector.

11. Drilling unit according to claim 9, characterized in that said means comprises a fan.

12. Drilling unit according to claim 2, characterized in that the partition wall (17) is completely air-proof.

13. Drilling unit according to claim 10, characterized in that said means comprises a fan.

14. Drilling unit according to claim 2, characterized in that the partition wall (17) forms a substantially air-proof bulkhead between the first and second parts (18, 19) of the engine house (8).

15. Drilling unit according to claim 3, characterized in that the partition wall (17) forms a substantially air-proof bulkhead between the first and second parts (18, 19) of the engine house (8).

16. Drilling unit according to claim 2, characterized in that the partition wall (17) abuts closely against the chassis along the inner circumference thereof.

17. Drilling unit according to claim 3, characterized in that the partition wall (17) abuts closely against the chassis along the inner circumference thereof.

18. Drilling unit according to claim 4, characterized in that the partition wall (17) abuts closely against the chassis along the inner circumference thereof.

19. Drilling unit according to claim 2, characterized in that the chassis (3, 4) in the part that encases the second part (19) of the engine house (8) is provided with at least one air inlet opening (20).

20. Drilling unit according to claim 3, characterized in that the chassis (3, 4) in the part that encases the second part (19) of the engine house (8) is provided with at least one air inlet opening (20).
