By using the outlet pipe cover 901, the staff can better discharge the water inside the outlet pipe 9. By setting a valve, it is more convenient for the staff to discharge the heated asphalt cold material. By setting the feed cover 501, foreign matter can be prevented from entering from the inside of the feed port 5 to affect the use of the device.
