Problems solved by technology
[0004] A large amount of iron filings will be generated during the milling operation of the rail. If the iron filings are left directly on the track, it will not only cause waste, but may also affect the normal operation of the locomotive on the track. Therefore, it is necessary to collect the iron filings
At present, the existing orbital milling and grinding vehicles mainly perform milling and collecting operations, and there is no effective overall solution for the subsequent transportation of iron filings

The invention discloses a chip collecting system. One end of a chip collecting pipe is connected to a chip collecting opening in the top of chip collecting box, and the other end of the chip collecting pipe extends into the working surface of a milling device. An induced draft fan is arranged at the front end of the chip collecting box and exhausts air in the chip collecting box, so that a negative pressure environment is formed in the chip collecting box. The air forms an air current in the chip collecting pipe, and the air current drives iron chips to move into the chip collecting box. A spiral conveying device is arranged at the bottom of the chip collecting box and comprises a chip conveying channel and a spiral conveying rod. One end of the spiral conveying rod is provided with a discharging motor which is in transmission connection with the spiral conveying rod through a gearbox, and the other end of the spiral conveying rod is provided with a discharging door. A conveying belt is arranged below a vehicle frame. The iron chips discharged from the discharging door is carried and conveyed through the conveying belt. The chip collecting system comprises collecting, storing, discharging and further transferring of the iron chips, the iron chips are collected and processed in a centralized mode, and all aspects of requirements of track milling and grinding maintenance can be met. The invention further provides a milling and grinding vehicle which can achieve the same technical effect.
Description
technical field [0001] The present invention relates to the technical field of track maintenance equipment, and more specifically relates to an airborne debris collection system. The invention also relates to a milling and grinding machine provided with said onboard chip collection system. Background technique [0002] The rail milling and grinding train is a new type of rail repair equipment, which removes rail surface materials by means of forming milling through several groups of milling cutters, eliminates rail defects, and improves ride comfort. The rail milling and grinding train has a large milling depth in one pass, and the operation can be completed in one pass, and the operation speed can reach 2500m / h. There is no spark, dust, etc. during the working process, iron filings can be collected, and the environment is friendly. Horizontal and longitudinal repairs have high precision, low maintenance cost, good line adaptability, no need to dismantle guard rails and si...
