Abstract:
Provided are an anti-blocking device, a concrete conveying pipe, a concrete pump truck, and an anti-blocking control method. The anti-blocking device comprises: a vibration device (100) and a pressure measurement device (600); the vibration device (100) is connected to a pipeline (200) and can be switched between a vibration state and a stationary state; and the pressure measurement device (600) is connected to the pipeline (200) and used for measuring a pressure value in the pipeline (200). The anti-blocking device for the concrete conveying pipe can adjust the operation state and vibration frequency of the vibration device according to the measured pressure value in the pipeline. The anti-blocking device is simple in structure, not only can effectively prevent the pipeline from being blocked, but also can quickly unblock the blocked pipeline.
