[0055] The key technical points and innovations of the technical solution of this embodiment are as follows:

[0056] 1. The railway drainage ditch dredging vehicle needs to be equipped with its own power source and is towed by a traction locomotive during transportation and movement.

[0058] When stopping the dredging operation, the robotic arm is retracted and locked onto the railway flatcar. The rectification device is within the railway locomotive clearance and can be towed to the next operation area by a traction locomotive.

[0059] 2. The working device is integrated onto the railway flatcar and can be loaded and unloaded integrally, which is convenient, flexible, and low-cost. A complete set of working devices including suction dredging, pipeline pneumatic conveying, collection, filtration, and conveyor belt discharging are integrated, integrating heavy manual operations and realizing mechanized operations.

[0060] Mechanizing the dredging of railway drainage ditches improves the operation efficiency, reduces the labor intensity, improves the quality of railway drainage ditch dredging, saves costs, and makes the operation more simple and fast.

[0061] Performing high-quality dredging operations on railway drainage ditches eliminates the hidden dangers to railway flood control and potential hazards to railway transportation caused by drainage ditch blockages.

[0062] Collecting and transporting the dirt to the designated area for unloading reduces secondary damage.

[0063] Through program control, the automated operation of railway drainage ditch dredging can be further realized.

[0064] On the basis of this embodiment, a PLC controller is added to control the automated operation of railway drainage ditch dredging through programming, further improving the operation efficiency.

[0065] In addition, for the railway drainage ditch dredging vehicle and its dredging method described in this embodiment, the railway flatcar can be replaced with a road transportation flatcar to meet the demand for non-railway drainage ditch dredging.
