A cutoff saw and filtration system provides convenient multi-stage filtration for a cutoff saw. The filters are effective in capturing the dust and debris created by the saw without becoming clogged. The filters may be easily cleaned and serviced.
대표청구항▼
1. A cutoff saw dust collection system comprising: a base;a table attached to the top of the base;a saw motor assembly pivotably attached to a back of the table and disposed above the table, the saw motor assembly having an arm extending forwards, a motor, a saw blade and a blade guard;a blade slot
1. A cutoff saw dust collection system comprising: a base;a table attached to the top of the base;a saw motor assembly pivotably attached to a back of the table and disposed above the table, the saw motor assembly having an arm extending forwards, a motor, a saw blade and a blade guard;a blade slot in the table aligned with the blade for receiving the blade therethrough, the blade slot having a back disposed adjacent to the back of the table and a front disposed away from the back of the table;a dust deflector attached to the table adjacent the back of the blade slot and extending upwardly from the surface of the table for directing dust through the blade slot, and wherein the dust deflector is pivotably mounted to the table such that the dust deflector is pivotable downwardly through a deflector slot in the table and wherein the dust deflector is biased to pivot upwardly to extend above the table. 2. The system of claim 1, wherein the dust deflector directs dust through the blade slot and into a plenum, the plenum being attached to the bottom of the table. 3. The system of claim 2, wherein dust is directed out of the base and into a vacuum. 4. The system of claim 2, further comprising a filter cloth, said filter cloth defining a debris collection chamber, and wherein dust moves out of the plenum, through a plenum port, and into said debris collection chamber. 5. The system of claim 4, wherein said debris collection chamber is defined by a filter bag. 6. The system of claim 4, wherein said filter cloth is attached to a drawer which is extendable from the base to thereby empty the debris collection chamber. 7. The system of claim 4, further comprising a canister filter, and wherein air flows through the blade slot, into the plenum, into the debris collection chamber, through the filter cloth, through the canister filter, and out of the base. 8. The system of claim 2, further comprising a canister filter, and wherein air flows through the blade slot, into the plenum, through the canister filter, and out of the base. 9. The system of claim 1, wherein the dust deflector has a side plate generally parallel to the saw blade and a curved rear channel attached to the side plate and extending behind the blade, the curved rear channel extending upwardly and forwards from the table. 10. The system of claim 1, wherein the dust deflector passes through the table between a first position where the dust deflector extends above the surface of the table and a second position where the dust deflector is disposed beneath the surface of the table. 11. A cutoff saw dust collection system comprising: a base;a table attached to the top of the base;a blade slot formed through the table for receiving a saw blade therethrough;a saw motor and saw blade mounted above the table adjacent a back of the table such that the saw motor is pivotable down towards the table to cut an object; anda dust deflector attached to the table via a pivot which is disposed beneath the table such that the dust deflector is disposed adjacent a back of the blade slot to direct dust from the saw blade through the blade slot and into the base, the dust deflector being movable through an opening in the table upwardly to a first position above the table and downwardly to a second position beneath the table. 12. The system of claim 11, wherein the dust deflector moves through a deflector slot formed in the table to pivot between the first position where the dust deflector is disposed above the table and the second position where the dust deflector is disposed below the surface of the table. 13. The system of claim 12, further comprising a biasing member attached to the dust deflector and the table to bias the dust deflector upwardly into the first position. 14. The system of claim 12, wherein a front edge of the dust deflector is angled upwardly relative to an upper surface of the table such that sliding an object rearwardly along the table against the dust deflector pushes the dust deflector beneath the table into the second position. 15. The system of claim 11, wherein the dust deflector comprises a side plate extending parallel to the blade slot and a curved rear channel which curves around a back of the blade slot. 16. The system of claim 11, wherein a front edge of the dust deflector is angled upwardly relative to an upper surface of the table such that sliding an object rearwardly across the surface of the table against the dust deflector pushes the dust deflector downwardly into the second position. 17. The system of claim 11, further comprising a biasing element attached to the dust deflector and the table to bias the dust deflector upwardly to the first position. 18. The system of claim 11, wherein the dust deflector comprises a curved rear channel which curves around a back of the blade slot and which is angled forwardly relative to the table to deflect dust downwardly and through the blade slot. 19. The system of claim 18, wherein the dust deflector further comprises a side plate attached to the rear channel, the side plate extending forward from the rear channel and upwardly from an upper surface of the table in a direction parallel to the blade slot.
