The invention relates to the technical field of concrete recycling equipment, in particular to a cleaning and recycling device and method for a concrete transport vehicle. The cleaning and recycling device for the concrete transport vehicle comprises a water storage tank, a vehicle washing device, a sand and stone separating screen, a wet concrete recycling machine, a silt tank and a cyclone separator, wherein water is supplied to the vehicle washing device by the water storage tank, the sand and stone separating screen undertakes muddy water drained by the vehicle washing deice and separate stone out from muddy water, the wet concrete recycling machine separates out sand, the silt tank undertakes muddy water drained by the wet concrete recycling machine, the cyclone separator extracts muddy water in the silt tank to separate out fine mud sand materials and sends the fine mud sand materials back to the wet concrete recycling machine, and recycled water formed after treatment is sent tothe water storage tank. Materials for cleaning the concrete transport vehicle are gradually classified and recycled through the multi-stage device, water resource recycling is realized, the device has large treatment capacity, and simultaneous cleaning of multiple concrete transport vehicles can be realized.
