Abstract

A debris collecting system comprises a debris collecting assembly including an air-flow generating device and a debris body. The system further comprises an intermediate debris collecting container connected to the debris collecting assembly such that the collected debris is by-passing the debris body of the assembly.

Claims (14)

1. A debris collecting system comprising:

an assembly including an air-flow generating device configured to apply debris conveying air to the system and a debris body configured to collect debris;

a debris collecting container placed in close proximity to the assembly;

a first conveying pipe having a debris-receiving portion and a debris body portion, the debris-receiving portion being configured to receive debris to be removed and the debris body portion being connected to the debris body;

a second conveying pipe having a first end portion connected to the debris body portion of the first conveying pipe and a second end portion connected to the debris collecting container, wherein airborne debris is caused to travel through the first and second conveying pipes and is separated from the conveying air and collected in the debris collecting container; and

a third conveying pipe arranged with a first end portion in the debris collecting container and a second end portion connected to a filtration system configured to receive the conveying air and filtrate remaining debris from the conveying air.

2. The debris collecting system of claim 1 , wherein the debris body comprises a first opening through which the debris body portion of the first conveying pipe is introduced and a second opening through which the first end portion of the second conveying pipe is introduced such that the first end portion of the second conveying pipe is connected to the debris body portion of the first conveying pipe inside the debris body.

3. The debris collecting system of claim 2 , wherein the first end portion of the second conveying pipe is connected to the debris body portion of the first conveying pipe with a compression seal.

4. The debris collecting system of claim 1 , further comprising a conveying pipe adapter connecting the first end portion of the second conveying pipe to the debris body portion of the first conveying pipe.

5. The debris collecting system of claim 4 , wherein the adapter is coaxially slidable attached on the debris body portion of the first conveying pipe.

6. The debris collecting system of claim 1 , wherein the debris body portion of the first conveying pipe is connected to a top of the debris body such that the first end portion of the second conveying pipe is connected to the debris body portion of the first conveying pipe outside the debris body.

7. The debris collecting system of claim 1 , wherein the system is configured to collect debris in front of the assembly.

8. The debris collecting system of claim 1 , wherein the system is configured to collect debris behind the assembly.

9. The debris collecting system of claim 1 , wherein the air-flow generating device is a vacuum source.
